Technical Field

The invention relates to a gear shaft System (zahnville-System) with the features of patent claim 1 and to a method for assembling a gear shaft System with the features of patent claim 12.

Background

The functional element with the internal toothing (Innenverzahnung), such as, for example, a sensor wheel (Geberrad) for a crankshaft position signal, and/or a cam, can be fixed at the toothed shaft by pressing the functional element onto the toothed shaft in an overlapping manner or by pushing the functional element onto the toothed shaft with play, so that the subsequent fixing of the functional element at the toothed shaft is fixed by means of additional connecting elements and/or by means of elements for axial support.

DE 102016111029 a1 describes a gear shaft system and a method for the production thereof. The toothed shaft system comprises a toothed shaft with an external toothing and a functional element with an internal toothing, which can be fixed or fastened to the toothed shaft. The external toothing has two adjacent toothing sections.

Furthermore, the assembly is at least significantly difficult, in particular if it does not even become impossible, for example via the pushing up of an automated force displacement control (Kraft-Weg-gesteuertes) or the incorporation of a high splicing force (F ü gekraft) for the sensor wheel and a low search force (Suchkraft) for the cam part, for example, and, if not even impossible.

Disclosure of Invention

The invention is therefore based on the object of designing and improving the previously mentioned gear shaft system and the assembly method in such a way that a simple assembly is possible.

The object on which the invention is based is achieved by a gear shaft system having the features of patent claim 1 and by an assembly method having the features of patent claim 12.

The toothed shaft system here comprises a toothed shaft and a functional element that can be fixed or fixed to the toothed shaft. The toothed shaft has an outer toothing which extends in particular parallel to the axis of rotation of the toothed shaft. The functional element has an internal toothing, which can also be designed in particular to extend parallel to the axis of rotation of the toothed shaft. The external toothing of the toothed shaft and the internal toothing of the functional element can be in engagement or can be designed to be in engagement with each other.

In particular, one of the teeth that can be engaged or meshed with each other has a first tooth recess and a second tooth recess, and the other of the teeth that can be engaged or meshed with each other has a press-fit tooth (Pressverzahnung). In this case, a particularly free mating toothing (Passverzahnung) can be formed or formed by engaging the press-fit teeth in the first toothing recesses. By engaging the press-fit toothing in the second toothing recess, in particular the press-fit toothing or the free mating toothing can be formed or formed. In particular, a section without teeth can be formed adjacent to the first and second tooth recesses. In this case, the toothless section can be arranged and/or configured in particular adjacent to both the first and the second tooth recess.

In an assembly method for a gear spindle system of this type, for example, in method step a), the internal toothing of the functional element is pushed onto the external toothing of the gear spindle in such a way that the press-fit teeth engage in the first toothing recesses and form a clearance counter toothing. The internal toothing of the functional element is then pushed, for example, in method step b), in particular via the external toothing of the toothed shaft, onto one or the toothless segments. Via the toothless section, the internal toothing of the functional element is then rotated about the external toothing of the toothed shaft, for example in method step c). In this case, the internal toothing of the functional element can be rotated about the external toothing of the toothed shaft, for example, by an odd number of recesses and/or teeth, for example by one recess and/or one tooth. After the rotation, for example in method step d), the internal toothing of the functional element is pushed up, in particular pressed onto the external toothing of the toothed shaft, in such a way that the press-fit toothing engages into the second toothing recess and forms a press-fit toothing or a mating toothing without play.

In the case of an initial pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft, the angle of the functional element is oriented and the functional element is guided with play on the toothed shaft by engaging the press-fit toothing into the first toothing recess and the mating toothing, which is formed with play. This makes it possible for the functional element to be pushed approximately without force via the toothed shaft, also over a relatively long meshing region. Furthermore, by engaging the press-fit teeth in the first tooth recesses, damage to the second tooth recesses can be avoided in the event of pushing the functional element onto the gear shaft. In this way, a high meshing quality can be achieved, in particular by means of a designed pressing toothing which engages behind the pressing toothing in the second toothing recess. After the internal toothing of the functional element has been pushed onto the external toothing of the toothed shaft, the internal toothing of the functional element can then be rotated about the external toothing of the toothed shaft via the section without toothing adjacent to the region of meshing. The possibility of rotation of the internal toothing of the functional element relative to the external toothing of the gear shaft by the toothless section can in turn make it possible for the press-on toothing which initially engages in the first toothing recess to engage in the second toothing recess after rotation. Since the toothless section can likewise adjoin the second tooth gap, the internal toothing of the functional element can be pushed up, in particular pressed onto the external toothing of the toothed shaft, for example directly after the rotation, in such a way that the pressing toothing engages into the second tooth gap and the pressing toothing or the mating toothing without play is formed. Alternatively, there may also be only one tooth segment which is completely passed through, then the functional element is rotated and thereafter the inner tooth is moved back into one of the other tooth gaps of the toothed shaft. By engaging the press-fit toothing in the second toothing recess and forming the press-fit toothing or the mating toothing without play, the functional element can be fastened to the toothed shaft, where an additional working step and/or an additional connecting element and/or an axial support are necessary. In this way, the system can be assembled in a simple manner. In particular, this likewise makes it possible to push the functional element onto the gear shaft, for example, with an automated force distance control. Furthermore, the toothed shaft can be provided in a simple manner, for example by providing such an external toothing and the functional element with such an internal toothing in the axial shape (Axialform) of the die (Matrix), in particular during operation (Arbeitsgang).

The toothless section can be formed after the toothed section equipped with the first toothing recess, in particular with regard to the initial push-up direction (on which the internal toothing of the functional element begins to be pushed up onto the external toothing of the toothed shaft).

In one embodiment, the outer toothing of the toothed shaft has a first and a second toothing recess and the inner toothing of the functional element has a press-fit toothing. The toothed shaft can have (among other things) a section without teeth. In this case, the toothless sections can be formed in particular at the tooth axis, for example in the form of first and second tooth recesses adjacent to the outer teeth of the tooth axis. In particular, the toothless section can be formed in this case after the tooth section of the outer tooth of the toothed shaft, which section is equipped with tooth gaps, with respect to the initial push-up direction (on which the inner tooth of the functional element begins to be pushed up onto the outer tooth of the toothed shaft).

In a further embodiment, the internal toothing of the functional element has a first and a second toothing recess and the external toothing of the toothed shaft has a press-fit toothing. In particular, the functional element can have (in addition) a section without teeth. In this case, the toothless section can be formed in particular at the functional element, for example adjacent to the first and second tooth gaps of the internal toothing of the functional element. In particular, the toothless section can be formed here in relation to the initial push-up direction (on which the internal toothing of the functional element begins to be pushed up onto the external toothing of the toothed shaft) after the toothing section of the internal toothing of the functional element which is equipped with the first toothing system recess.

In a further embodiment, the first tooth recess and the second tooth recess are formed in a particularly common tooth section of the tooth, for example the outer tooth of the toothed shaft or the inner tooth of the functional element, and are arranged in a distributed manner, in particular on their circumference. In particular, the first and second tooth recesses can be formed in the same tooth section of the tooth, for example the outer tooth of the toothed shaft or the inner tooth of the functional element, and are arranged distributed, in particular distributed, over the circumference thereof. This makes it possible to minimize the axial length of the teeth for fastening the functional element, for example the outer teeth of the toothed shaft or the inner teeth of the functional element. In this way, for example, the axial length of the toothed shaft can be shortened and/or construction space, for example, for a plurality of such fixed functional elements and/or other components, can be made available. In this case, the toothless section can be arranged and/or formed adjacent to a, in particular common, toothed section equipped with a first and a second toothing recess of the toothing, for example the outer toothing of the toothed shaft or the inner toothing of the functional element. In particular, the toothless section can be formed in this case with respect to the initial push-up direction (on which the internal toothing of the functional element begins to be pushed up onto the external toothing of the toothed shaft) after an especially common toothing section of the toothing, for example of the external toothing of the toothed shaft or of the internal toothing of the functional element, which is equipped with the first and second toothing recesses.

In the context of the assembly method, as already explained, first of all, for example in method step a), the inner toothing of the functional element can be pushed onto the outer toothing of the toothed shaft in such a way that the press-fit teeth engage in the first toothing recesses, and then for example in method step b), the inner toothing of the functional element is pushed via the outer toothing of the toothed shaft up to the section without toothing and then for example in method step c) is rotated about the outer toothing of the toothed shaft via the section without toothing of the inner toothing of the functional element. After the rotation, for example in method step c), the internal toothing of the functional element can then be pushed back, for example in method step d), in a direction which is in particular opposite to the starting direction of movement (which can also be referred to as the push-up direction of the press-fit toothing), in particular onto the external toothing of the toothed shaft, in such a way that the press-fit toothing engages into the second toothing recess and forms a press-fit toothing or a mating toothing without play.

If appropriate, the first and second tooth recesses can be formed in a single tooth section of the tooth and arranged distributed over the circumference thereof.

In particular, the toothed shaft may however also have two or more such, in particular common, toothed segments, each of which has a first and a second toothed recess arranged distributed over their circumference and, respectively, a section arranged behind and/or between them and/or formed without teeth. In this way, two or more functional elements can be fixed at the gear shaft and/or in different positions, for example by means of an assembly method.

In a further embodiment, the first tooth recess is formed in a first tooth section of the tooth, for example the outer tooth of the toothed shaft or the inner tooth of the functional element, and the second tooth recess is formed in a second tooth section of the tooth, for example the outer tooth of the toothed shaft or the inner tooth of the functional element. This makes it possible to push the functional element approximately onto the larger axial path of the gear shaft without force. In this case, the toothless section can be arranged and/or formed in particular between a first tooth section of a tooth, for example an outer tooth of a toothed shaft or an inner tooth of a functional element, which is equipped with first tooth recesses, and a second tooth section, which is equipped with second tooth recesses. In this case, the toothless section makes it possible to rotate the internal toothing of the functional element relative to the external toothing of the toothed shaft, which in turn makes it possible to utilize installation space in different radial spatial directions in the case of an initial push-up and in the case of a subsequent push-up with press-fit engagement and in this way simplifies assembly and in particular also makes it possible to assemble complex systems and/or systems with complex installation space conditions.

In this case, for example, the toothless section can be formed between a first tooth section, equipped with first tooth recesses, of a tooth, for example an outer tooth of a tooth shaft or an inner tooth of a functional element, and a second tooth section, equipped with second tooth recesses, for example at the tooth shaft or at the functional element. In particular, the toothless section can be formed here, with respect to the initial push-up direction (on which the internal toothing of the functional element begins to be pushed up onto the external toothing of the toothed shaft), after the first toothing section equipped with the first toothing recesses of the toothing, for example the external toothing of the toothed shaft or the internal toothing of the functional element, and before the second toothing section equipped with the second toothing recesses.

In this case, the radial positions of the first tooth recess of the first tooth section and the second tooth recess of the second tooth section can coincide with one another or in particular differ from one another, for example be twisted at a defined angle.

In the context of the assembly method, as already explained, first of all, for example in method step a), the inner toothing of the functional element can be pushed onto the outer toothing of the toothed shaft in such a way that the press-fit teeth engage in the first toothing recesses of the first toothing section, and then for example in method step b), the inner toothing of the functional element is pushed via the outer toothing of the toothed shaft, in particular via the first toothing section, onto the section without toothing, and then for example in method step c), the inner toothing of the functional element is rotated about the outer toothing of the toothed shaft on the section without toothing. After the rotation, for example in method step c), the internal toothing of the functional element can then be pushed on, in particular onto the external toothing of the toothed shaft, in the same direction or in the initial push-on direction (which can also be referred to as the push-on direction of the press-on toothing, for example, at this time), in such a way that the press-on toothing engages into the second toothing recess of the second toothing section and forms a press-on toothing or a mating toothing without play.

In particular, the first tooth recess and the second tooth recess can be arranged and/or formed symmetrically, for example rotationally symmetrically, distributed over the circumference of the tooth, for example the outer tooth of the tooth shaft or the inner tooth of the functional element.

In a special embodiment, the first tooth recesses and the second tooth recesses are arranged and/or formed alternately with one another. In this case, in the context of the assembly method, the internal toothing of the functional element can be rotated relative to the external toothing of the toothed shaft, in particular by an odd number of recesses and/or teeth, for example by one recess and/or one tooth. For example, the toothing provided with the first and second tooth gaps, for example the outer toothing of the toothed shaft or the inner toothing of the functional element, may be designed in the form of a double-tooth profile (doppelzahnprofile) with first and second tooth gaps arranged alternately one with the other. In this way, not only a particularly easy pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft can be achieved, but also a particularly high mechanical stability of the fixing of the functional element at the toothed shaft can be achieved.

In a further embodiment, another of the toothed sections that can be or can be engaged with each other (for example the internal toothed section of the functional element or the external toothed section of the toothed shaft) additionally has guide toothing, i.e. press toothing and guide toothing. By engaging the guide toothing in the first toothing recess and/or in the second toothing recess, in particular a free mating toothing can be formed or formed.

For example, the outer toothing of the toothed shaft can have a first and a second toothing recess and the inner toothing of the functional element can have a press toothing and a guide toothing or the inner toothing of the functional element can have a first and a second toothing recess and the outer toothing of the toothed shaft can have a press toothing and a guide toothing.

In the context of this assembly method, for example in method step a), the internal toothing of the functional element can be pushed onto the external toothing of the toothed shaft in such a way that the pressing toothing engages in the first toothing recess and the guide toothing engages in the second toothing recess and forms a free mating toothing. As already explained, then, for example in method step b), the internal toothing of the functional element can be pushed over the external toothing of the toothed shaft onto the section without toothing, and for example in method step c), the internal toothing of the functional element is rotated about the external toothing of the toothed shaft on the section without toothing. After the rotation, for example in method step c), the internal toothing of the functional element can then be pushed up, for example in method step d), in particular onto the external toothing of the toothed shaft in such a way that the pressing toothing engages into the second toothing recess and forms a pressing toothing or a mating toothing without play, and the guide toothing engages into the first toothing recess and forms a mating toothing with play.

In the case of an initial pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft, the angle of the functional element can be oriented and the functional element can be guided with play on the toothed shaft by engaging the guide toothing into the second toothing recess and configuring the clearance of the mating toothing. This also makes it possible for the functional element to be pushed approximately onto the toothed shaft without force, also over a relatively long meshing region. Furthermore, by engaging the guide toothing in the second toothing recess, damage to the pressing toothing in the event of pushing the functional element onto the toothed shaft can be avoided. In this way, a high meshing quality of the toothed press-on part, which is formed in particular by the engagement of the press-on toothing into the second toothing recess after the pressing of the toothed press-on toothing, can be achieved. After the internal toothing of the functional element has been pushed onto the external toothing of the toothed shaft, the internal toothing of the functional element can then be rotated about the external toothing of the toothed shaft in the section without toothing adjacent to the first and second toothing recesses. The possibility of rotation of the internal toothing of the functional element relative to the external toothing of the gear shaft by the toothless section can in turn make it possible for the guide toothing which initially engages in the second toothing recess to engage in the first toothing recess after rotation. Since the section without toothing can likewise adjoin the first toothing recess, the internal toothing of the functional element can then be pushed onto the external toothing of the toothed shaft, for example directly after the rotation, in such a way that the press-fit toothing engages into the second toothing recess and forms the press-fit toothing or the spaced mating toothing and the guide-fit toothing engages into the first toothing recess and also forms the spaced mating toothing. In this way, the system can be assembled in a simple manner. In particular, this also makes it possible to push the functional element onto the gear shaft, for example, with an automated force displacement control. Furthermore, the toothed shaft can be provided in a simple manner, for example by providing such an external toothing and the functional element with such an internal toothing in the axial shape of the die, in particular during operation.

The pressing toothing and the guide toothing can be formed, for example, in a particularly common toothing section of the toothing, for example the internal toothing of the functional element or the external toothing of the toothed shaft, and arranged, in particular, distributed over the circumference thereof. In particular, the press toothing and the guide toothing can be formed in the same tooth section, if appropriate in a single tooth section of the tooth, for example the internal tooth of a functional element or the external tooth of a toothed shaft, and arranged distributed over their circumference. This makes it possible to minimize the axial length of the toothing (for example the internal toothing of the functional element or the external toothing of the toothed shaft) for fixing the functional element. In this way, for example, the axial length of the toothed shaft can be shortened and/or a construction space can be made available, for example, for a plurality of such fixed functional elements and/or other components.

In particular, the press toothing and the guide toothing can be arranged and/or formed symmetrically, for example rotationally symmetrically, distributed over the circumference of a toothing, for example an internal toothing of a functional element or an external toothing of a toothed shaft.

In a special embodiment, the pressing toothing and the guiding toothing are arranged and/or formed alternately with respect to one another. In this case, in the context of the assembly method, the internal toothing of the functional element is rotated with respect to the external toothing of the toothed shaft, in particular with an odd number of recesses and/or teeth, for example with one recess and/or one tooth. For example, the toothing system equipped with the press toothing and the guide toothing, for example the internal toothing system of a functional element or the external toothing system of a toothed shaft, can be designed in the form of a double-tooth profile with alternately arranged press toothing and guide toothing. In this way, not only a particularly easy pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft can be achieved, but also a particularly high mechanical stability of the fastening of the functional element at the toothed shaft can be achieved.

Furthermore, the toothing provided with the first and second toothing recesses, for example the outer toothing of the toothed shaft or the inner toothing of the functional element, can have a spacing between the first and/or second toothing recesses and/or meshing teeth which delimit the first and/or second toothing recesses.

Similarly, the toothing system equipped with the press-fit teeth and optionally the guide toothing, for example the internal toothing system of the functional element or the external toothing system of the toothed shaft, has spaces between the press-fit teeth and/or optionally the guide toothing system teeth and/or defines the toothing system recesses of the press-fit teeth and/or optionally the guide toothing system teeth.

In this case, the spacing of one tooth (for example the outer tooth of the toothed shaft or the inner tooth of the functional element) and/or the spacing of the meshing teeth defining the first and/or second tooth spaces and the spacing of the other tooth (for example the inner tooth of the functional element or the outer tooth of the toothed shaft) and/or the tooth spaces defining the pressing meshing teeth and/or, if appropriate, the guide meshing teeth can mesh or mesh with one another. In this case, a gap-forming counter toothing can be formed or embodied in particular by the spacing of one toothing system (for example the outer toothing system of the toothed shaft or the inner toothing system of the functional element) and/or the meshing teeth defining the first and/or second toothing system recesses engaging into the spacing of the other toothing system (for example the inner toothing system of the functional element or the outer toothing system of the toothed shaft) and/or the teeth recesses defining the pressing mesh and/or, if appropriate, the guiding mesh.

In the context of the assembly method, the inner toothing of the functional element can be pushed onto the outer toothing of the toothed shaft in such a way that the press-fit toothing engages into the first toothing recess (and if appropriate the guide toothing engages into the second toothing recess) and the spaced-apart and/or toothing teeth defining the first and/or second toothing recesses engage into the spaced-apart and/or toothing recesses defining the press-fit toothing and/or if appropriate the guide toothing, and in particular a gapped mating toothing is formed in each case. After the rotation, the inner toothing of this functional element can be pushed up, in particular pressed onto the outer toothing of the toothed shaft, in particular in such a way that the pressing toothing engages into the second toothing recess and forms the pressing toothing (and if appropriate the guide toothing engages into the first toothing recess and forms a free mating toothing) and spaces and/or the toothing defining the first and/or second toothing recesses engages into the spaces and/or the toothing recesses defining the pressing toothing and/or if appropriate the guide toothing and forms a free mating toothing.

The formation of the spaced mating teeth by engaging the press-fit teeth in the first tooth recesses or the formation of the press-fit teeth or the spaced mating teeth by engaging the press-fit teeth in the second tooth recesses or the formation of the spaced mating teeth by engaging the guide tooth recesses in the first and/or second tooth recesses or the formation of the spaced mating teeth by engaging the spaced and/or defined first and/or second tooth recesses in the spaced and/or defined press-fit teeth and/or, if appropriate, guide tooth recesses of the guide tooth system can be controlled by adjusting a number of different parameters of the teeth which can be engaged or engaged with one another, for example by adjusting the root circle diameter (Fu kreisduchmeater) and/or the gap width and/or the tip circle diameter (kopfkreisduchmeater) and/or the tooth height and/or the tooth thickness and/or the tooth flank angle (flankenkel) and/or the gap and/or the tooth thickness and/or the tooth flank angle (flankenkel) of the teeth The shape of the teeth.

In a special embodiment, for this purpose, the first tooth recesses of the external toothing of the toothed shaft have a smaller root circle diameter than the second tooth recesses of the external toothing of the toothed shaft. In this case, the press-fit teeth of the internal toothing of the functional element can have, in particular, a tip circle diameter which is greater than a root circle diameter of a first tooth recess of the external toothing of the toothed shaft and which is less than or equal to a root circle diameter of a second tooth recess of the external toothing of the toothed shaft. In this way, it is possible to bring about the press-fit toothing engaging with play in the first toothing recess in the case of an initial pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft and to form a fitted toothing with play, and in the case of an subsequent pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft, after rotation, without play, into the second toothing recess and to form a press-fit toothing and to fix the functional element at the toothed shaft in this way. The guide toothing of the internal toothing of the functional element may have, for example, a tip circle diameter which is greater than a tip circle diameter of the press toothing of the internal toothing of the functional element and/or greater than a root circle diameter of a first tooth recess of the external toothing of the toothed shaft and/or greater than a root circle diameter of a second tooth recess of the external toothing of the toothed shaft. This can be brought about in that the guide toothing engages with play in the second toothing recess both in the case of initial pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft and in the case of subsequent pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft into the first toothing recess after rotation and can be formed as a mating toothing with play.

In a further special embodiment, which is configured in particular in contrast to the previous special embodiment, for this purpose the first tooth recesses of the internal toothing of the functional element have a larger root circle diameter than the second tooth recesses of the internal toothing of the functional element. The press-fit teeth of the external toothing of the toothed shaft can have a tip circle diameter which is smaller than the root circle diameter of the first tooth recesses of the internal toothing of the functional element and which is greater than or equal to the root circle diameter of the second tooth recesses of the internal toothing of the functional element. This also makes it possible for the press-fit teeth to engage with play in the first tooth recesses and to form a mating tooth with play in the case of an initial pushing-up of the internal tooth of the functional element onto the external tooth of the toothed shaft, and to engage without play in the second tooth recesses and to form a press-fit tooth after rotation in the case of a subsequent pushing-up of the internal tooth of the functional element onto the external tooth of the toothed shaft and to fix the functional element on the toothed shaft in this way. The guide toothing of the external toothing of the toothed shaft may have, for example, a tip circle diameter which is smaller than a tip circle diameter of the press toothing of the external toothing of the toothed shaft and/or smaller than a root circle diameter of the first tooth recess of the internal toothing of the functional element and/or smaller than a root circle diameter of the second tooth recess of the internal toothing of the functional element. This can likewise be brought about in that the guide toothing can engage with play into the second toothing recess both in the case of an initial pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft and in the case of a subsequent pushing-up of the internal toothing of the functional element onto the external toothing of the toothed shaft can engage with play into the first toothing recess after rotation and can be designed as a mating toothing with play.

The functional element may for example comprise or be a sensor wheel and/or a cam and/or a hub, in particular a sensor wheel, for example for a sensor, for example for a camshaft position signal.

The toothed shaft system can be designed, for example, for a motor vehicle. For example, the gear shaft system can be designed for a motor vehicle with an internal combustion engine, for example with a gasoline engine or a diesel engine.

The disadvantages mentioned at the outset are thus avoided and corresponding advantages are achieved.

Detailed Description

Fig. 1 to 6 show various embodiments of a toothed shaft system 100, for example for a motor vehicle, for example with an internal combustion engine, comprising a toothed shaft 10 and a functional element 20, for example a sensor wheel and/or a cam and/or a hub, for example for a sensor, which is fastened to the toothed shaft 10. In this case, the toothed shafts 10 each have an external toothing 11 running parallel to the axis of rotation of the toothed shafts 10 and the functional elements 11 each have an internal toothing 21, wherein the external toothing 11 of the toothed shafts 10 and the internal toothing 21 of the functional elements 20 can mesh or mesh with one another.

In the embodiment shown in fig. 1 to 6, the teeth 11,21 that can mesh with one another or with one another each have a first tooth recess 11a,21a and a second tooth recess 11b,21 b. In this case, the other of the toothed sections 21, 11, which can be or can be engaged with one another, has at least one pressing toothing 21a,11 a. By engaging the press- fit teeth 21a,11a into the first tooth recesses 11a,21a, the mating teeth with play can be formed or formed, wherein by engaging the press- fit teeth 21a,11a into the second tooth recesses 11b,21b, the press-fit teeth or the mating teeth without play can be formed or formed.

Fig. 1 and 6 show that the segment 12 is arranged and/or formed adjacent to the first tooth recess 11a,21a and the second tooth recess 11b,21 b.

The gear shaft system 100 shown in fig. 1 to 6 can be assembled in particular in that the internal toothing 21 of the functional element 20 is pushed onto the external toothing 11 of the gear shaft 10 in such a way that the press- fit teeth 21a,11a engage in the first toothing recesses 11a,21a and form a gap-free mating toothing. The inner toothing 21 of the functional element 20 is then pushed via the outer toothing 11 of the toothed shaft 10 up to the toothless section 12. Via the toothless section 12, the internal toothing 21 of the functional element 20 then rotates about the external toothing 11 of the gear shaft 10. After this rotation, the internal toothing 21 of the functional element 20 is pushed onto the external toothing 11 of the toothed shaft 10 in such a way that the press-fit toothing 21a;11a is engaged in the second toothing recess 11b;21b and is formed as a press-fit toothing or as a mating toothing without play.

In the embodiment shown in fig. 1 to 5b, the first tooth recesses 11a,21a and the second tooth recesses 11b,21b are formed in an in particular common tooth section V of the teeth 11,21 and are distributed over the circumference of the teeth 11,21 and in particular are arranged alternately with one another.

Fig. 1 illustrates that the toothless section 12 is arranged and/or formed adjacent to the particularly common toothing section V of the toothing 11, which is equipped with the first and second toothing recesses 11a,11b, in particular with regard to the initial push-up direction a (on which the inner toothing 21 of the functional element 20 begins to be pushed up onto the outer toothing 11 of the toothed shaft 10).

In the context of the assembly method, the embodiment shown in fig. 1 to 5b can be assembled in particular by pushing the internal toothing 21 of the functional element 20 after rotation in a push-up direction P of the press-fit engagement, in particular opposite to the starting push-up direction a, in such a way, in particular onto the external toothing 11 of the toothed shaft 10, that the press- fit engagement 21a,11a engages in the second toothing recess 11b,21b and that the press-fit or clearance-free mating toothing is formed.

In the context of the embodiments shown in fig. 1 to 3b and 6, the external toothing system 11 of the toothed shaft 10 has a first and a second toothing system recess 11a,11b, and the internal toothing system 21 of the functional element 20 has a press-fit toothing system 21 a. The toothless section 12 can be formed here at the tooth axis 10, in particular adjacent to the first tooth recess 11a and the second tooth recess 11b of the outer tooth 11 of the tooth axis 10.

In contrast, in the context of the embodiment shown in fig. 4a to 5b, the inner toothing 21 of the functional element 20 has a first and a second toothing recess 21a,21b, and the outer toothing 11 of the toothed shaft 10 has a press-fit toothing 11 a. In this case, the toothless section (not shown) can be formed in particular at the functional element 20, in particular adjacent to the first and second tooth recesses 21a,21b of the inner toothing 21 of the functional element 20.

In the context of the embodiment shown in fig. 2a,2b, 5a and 5b, the toothing 21 is equipped with pressing toothing 21a,11a additionally has guiding toothing 21b,11b, which can be designed with a gap as a mating toothing by engaging into the first toothing recess 11a,21a and by engaging into the second toothing recess 11b,21 b. The pressing toothing 21a,11a and the guide toothing 21b,11b are designed and symmetrically distributed over the circumference of the toothing 21, 11, in particular in a common toothing section of the toothing 21, 11, and are arranged alternately with one another, for example in the form of a double-tooth profile. In the context of the assembly method, in the case of these embodiments, the internal toothing 21 of the functional element 20 can be pushed onto the external toothing 11 of the toothed shaft 10, in particular, in such a way that the press toothing 21a,11a engages in the first toothing recess 11a,21a and the guide toothing 21b,11b engages in the second toothing recess 11b,21b and forms a clearance counter toothing. After the rotation, the internal toothing 21 of the functional element 20 can then be pushed up, in particular onto the external toothing 11 of the toothed shaft 10, in such a way that the press toothing 21a,11a engages in the second toothing recess 11b,21b and forms the press toothing and the guide toothing 21b,11b engages in the first toothing recess 11a,21a and forms a clearance counter toothing.

Fig. 1 to 6 furthermore show that the toothing 11,21 provided with the first and second toothing system recesses 11a,11b,21a,21 b has a spacing between the first and second toothing system recesses 11a,11b,21a,21 b and is provided with a pressing toothing 21a,11a and, if appropriate, a toothing 21 leading to the toothing 21b,11b, and that the toothing 21 provided with the pressing toothing 21a,11a and, if appropriate, a spacing between the pressing toothing 21a,11a and, if appropriate, the guiding toothing 21b,11b has a spacing between the pressing toothing 21a,11a and, if appropriate, the guiding toothing 21b,11b and is provided with a pressing toothing 21a,11a and, if appropriate, a toothing 21b,11b, and that the toothing system provided with the pressing toothing 21a,11a and, if appropriate, a toothing 21b,11 c, and in particular, after the external toothing system 20 of the functional element 20 has been pushed onto the shaft 21, and is pushed onto the shaft 20 10 can mesh with one another or with one another after rotation, and in particular in both cases form a mating toothing with play.

Fig. 1 shows a first embodiment of the gear shaft system 100 in the assembled state and illustrates that in the assembled state of the gear shaft system 100, the press-on toothing 21a of the functional element 20 engages into the second toothing system recess 11b of the gear shaft 10 and forms a press-on toothing. The assembled gear shaft system 100 shown in figure 1 can be assembled in particular in that, that is, the press-fit engaging teeth 21a engage in the first tooth gaps 11a and form a gap mating tooth in the case of starting the pushing-up of the internal tooth 21 of the functional element 20 onto the external tooth 11 of the gear shaft 10, the inner toothing 21 of the functional element 20 is then pushed in the initial push-up direction a via the outer toothing 11 of the toothed shaft 10 up to the toothless section 12 and is rotated via the toothless section 12, for example, by one tooth 21a,11c and/or one recess 11a,11b,21c and is pushed again after rotation in the push-up direction P of the pressing toothing opposite the initial push-up direction a onto the outer toothing 11 of the toothed shaft 10, so that the pressing toothing 21a engages into the second tooth recess 11b and forms a pressing toothing.

In the context of the first embodiment shown in fig. 1, the guide toothing 21a of the functional element 10 is respectively missing, so that the guide toothing recess 21c overlaps the two teeth 11c accordingly. Fig. 1 also shows that the first tooth recess 11a of the toothed shaft 10 has a smaller root circle diameter than the second tooth recess 11b of the toothed shaft 10. Fig. 1 furthermore shows that the section without toothing adjoins a first tooth recess 11a and a second tooth recess 11b of the outer toothing 11 of the toothed shaft 10 at the toothed shaft 10. Fig. 1 shows that the functional element 20 can also have an external toothing 22, for example for the output of a further component and/or for the output of a signal.

The embodiment of the toothed shaft system 100 shown in fig. 2a and 2b differs from the embodiment shown in fig. 1 essentially by the tooth height and shape of the pressure toothing 21a and the guide toothing 21a of the functional element 20. In this way, the guide toothing 21b of the functional element 10 in the case of the embodiment shown in fig. 2a and 2b protrudes more and is formed with a greater tooth height than the guide toothing 21a of the functional element 20 of the embodiment shown in fig. 1. In this way, in the case of the embodiment shown in fig. 2a and 2b, the guide toothing 21b of the functional element 20 has a tooth height and a tip circle diameter in the order of magnitude of the tooth height and tip circle diameter of the press toothing 21a of the functional element 20, wherein the guide toothing 21b of the functional element 20 has a smaller tooth height and a larger tip circle diameter than the press toothing 21a of the functional element 20.

Fig. 2a, which shows the gear shaft system 100 during assembly, illustrates the engagement of the pressing toothing 21a into the first toothing recess 11a and the engagement of the guide toothing 21b into the second toothing recess 11b in the case of the initial pushing-up of the internal toothing 21 of the functional element 20 onto the external toothing 11 of the gear shaft 10, and the formation of a free mating toothing. In this case, the force acting on the pressing tooth 21a in the event of the start of pushing up and pushing in can be advantageously reduced by the guide tooth 21b, and thus the resulting damage at the pressing tooth 21a can be reduced and in this way the engagement quality of the pressing tooth system, which is formed in particular by engaging the pressing tooth 21a into the second tooth recess 11b, can be increased.

Fig. 2b shows the gear shaft system 100 shown in fig. 2a after assembly, in particular after the internal toothing 21 of the functional element 20 has been rotated about the external toothing 11 of the gear shaft 100, for example, with one tooth or with a gap on a toothless section (not shown), and after the internal toothing 21 of the functional element 20 has been pushed up again and in particular onto the external toothing 11 of the gear shaft 10, and illustrates that the press-on toothing 21a engages into the second toothing gap 11b and forms a press-on toothing, wherein the guide toothing 21b engages into the first toothing gap 11a and forms a gap counter toothing.

The second embodiment of the gear shaft system 100 shown in fig. 3a and 3b differs from the embodiment shown in fig. 1 and 2a and 2b essentially in that the internal toothing 21 of the functional element 20 has only the press toothing 21a, but not the guide toothing 21 b. In the embodiment shown in fig. 3a and 3b, the internal toothing 21 of the functional element 20 has half as many teeth, namely press-fit teeth 21a (e.g. the external toothing 11 of the toothed shaft 10), i.e. teeth 11c which are spaced apart and/or define the first and/or second toothing recesses 11a,11b, and/or two teeth, i.e. two teeth each, of the external toothing 11 of the toothed shaft 10 which are spaced apart and/or define the first and/or second toothing recesses 11a,11b engage in the recesses 21c of the internal toothing 21 of the functional element 20, i.e. in the toothing recesses 21c which are spaced apart and/or define the press-fit teeth 21 a.

Fig. 3a, which shows the gear shaft system 100 during assembly, illustrates that the guidance of the internal toothing 21 of the functional element 20 on the external toothing 11 of the gear shaft 10, in the case of an initial pushing-up of the internal toothing 21 of the functional element 20 onto the external toothing 11 of the gear shaft 10, can already be achieved only by the gap-free mating toothing or toothings which are formed by engaging the press-on toothing 21a into the first toothing space 11a (and by engaging the meshing teeth 11c which are spaced apart and/or define the first and/or second toothing spaces 11a,11b into the tooth spaces 21c which are spaced apart and/or define the press-on toothing). In this manner, the gear shaft system 100 and its assembly may be simplified.

Fig. 3b shows the gear shaft system 100 already shown in fig. 3a after assembly, in particular after a rotation of the inner toothing 21 of the functional element 20 relative to the outer toothing 11 of the gear shaft 10 on a toothless section (not shown) and after the inner toothing 21 of the functional element 20 has been pushed up again and in particular onto the outer toothing 11 of the gear shaft 10, and illustrates the case in which the press-on toothing 21a engages into the second toothing recess 11b and forms a press-on toothing, wherein the meshing teeth 11c, which are spaced apart and/or define the first and/or second toothing recesses 11a,11b, additionally engage into the spacing and/or the toothing recesses 21c, which define the press-on toothing, and form a gap mating toothing.

Fig. 2a and 3a illustrate that the configuration of the spaced mating and pressing toothing can be realized, for example, in that the first toothing recess 11a of the outer toothing 11 of the toothed shaft 10 is formed by a first toothing recess 11aHas a smaller root circle diameter f than a second tooth space 11b of the outer tooth 11 of the gear shaft 10_11aAnd the press-engaging teeth 21a of the internal toothing 21 of the functional element 20 have a tip circle diameter k_21aLarger than the root circle diameter f of the first tooth space 11a of the external tooth portion 11 of the gear shaft 10_11aAnd is less than or equal to the root circle diameter f of the second tooth space 11b of the external tooth portion 11 of the gear shaft 10_11b. Fig. 2a also shows that the guide toothing 21b of the internal toothing 21 of the functional element 20 may have a tip circle diameter k in this case_21bLarger than the tip circle diameter k of the press tooth 21a of the internal tooth system 21 of the functional element 10_21aAnd/or is larger than the root circle diameter f of the first tooth space 11a of the external tooth 11 of the gear shaft 10_11aAnd/or a root circle diameter f of the second tooth space 11b larger than the external tooth portion 11 of the gear shaft 10_11b。

The third embodiment of the gear shaft system 100 shown in fig. 4a and 4b differs from the embodiment shown in fig. 3a and 3b essentially in that the inner toothing 21 of the functional element 20 has a first and a second toothing recess 21a,21b and the outer toothing 11 of the gear shaft 10 has a press-fit toothing 11 a. In the embodiment shown in fig. 4a and 4b, the inner toothing 21 of the functional element 20 has twice as many teeth 21c, i.e., meshing teeth 21c which are spaced apart and/or define the first and/or second toothing recesses 21a,21b, such as the outer toothing 11 of the toothed shaft 10, i.e., the pressing toothing 11a, and/or two respective teeth, i.e., two respective spaced apart and/or meshing teeth 21c which define the first and/or second toothing recesses 21a,21b, of the inner toothing 21 of the functional element engage in the recess 11c, i.e., in the spacing of the outer toothing 11 of the toothed shaft 10 and/or in the toothing recess 11c which defines the pressing toothing 11 a.

Fig. 4a, which shows the gear shaft system 100 during assembly, illustrates that the guidance of the internal toothing 21 of the functional element 20 on the external toothing 11 of the gear shaft 10, in the event of an initial pushing of the internal toothing 21 of the functional element 20 onto the external toothing 11 of the gear shaft 10, can already be achieved only by the spaced, one or more mating toothing(s) which are formed by engaging the press-on toothing 11a into the first toothing recess 21a (and by engaging the spaced and/or defined first and/or second toothing recesses 21a,21b into the spaced and/or defined toothing recesses 11c of the press-on toothing 11 a). In this way, the gear shaft system 100 and its assembly can likewise be simplified.

Fig. 4b shows the gear shaft system 100 already shown in fig. 4a after assembly, in particular after a rotation of the inner toothing 21 of the functional element 20 relative to the outer toothing 11 of the gear shaft 10 on a toothless section (not shown) and after the inner toothing 21 of the functional element 20 has been pushed up again and in particular onto the outer toothing 11 of the gear shaft 10, and illustrates that the pressing toothing 11a now engages into the second toothing recess 21b and forms a pressing toothing, wherein the meshing teeth 21c, which are spaced and/or define the first and/or second toothing recesses 21a,21b, additionally engage into the tooth recesses 11c, which are spaced and/or define the pressing toothing 11a, and form a fitting toothing with play.

The fourth embodiment of the gear shaft system 100 shown in fig. 5a and 5b differs from the embodiment shown in fig. 1, 2a and 2b essentially in that the inner toothing 21 of the functional element 20 has a first and a second toothing recess 21a,21b and the outer toothing 11 of the gear shaft 10 has a pressing toothing 11a and a guide toothing 11 b.

Fig. 5a, which shows the gear spindle system 100 during assembly, illustrates that the guidance of the internal toothing 21 of the functional element 20 on the external toothing 11 of the gear spindle 10, in the case of an initial pushing of the internal toothing 21 of the functional element 20 onto the external toothing 11 of the gear spindle 10, can be achieved not only by one or more fitting toothings with play which are formed by engaging the press-on toothing 11a into the first toothing recess 21a (and by engaging the toothing 21c which is spaced apart and/or defines the first and/or second toothing recesses 21a,21b into the toothing recesses 11c which are spaced apart and/or define the press-on toothing 11a and/or the guide toothing 11b), but also by fitting toothings with play which are formed by engaging the guide toothing 11b into the second toothing recess 21 b. In this case, the guide toothing 11b advantageously reduces the forces acting on the pressure toothing 11a in the event of initial pushing up and shifting, and thus reduces the damage occurring at the pressure toothing 11a and in this way increases the engagement quality of the pressure toothing, which is formed in particular by engaging the pressure toothing 11a into the second toothing recess 21b later.

Fig. 5b shows the gear spindle system 100 shown in fig. 5a after assembly, in particular after a rotation of the internal toothing 21 of the functional element 20 relative to the external toothing 11 of the gear spindle 10, for example with one tooth or with a gap on a toothless section (not shown), and after the internal toothing 21 of the functional element 20 has been pushed up again and in particular onto the external toothing 11 of the gear spindle 10, and illustrates that the pressing toothing 11a now engages into the second toothing gap 21b and forms a pressing toothing, wherein the guide toothing 11b engages into the first toothing gap 21a and forms a gap-carrying counter toothing in addition, and wherein the spaced and/or gap-carrying teeth 21c of the first and/or second toothing gaps 21a,21b additionally engage into the space and/or define the pressing toothing 11a and/or the gap-carrying toothing 11c of the guide toothing 11b and forms a gap in addition .

Fig. 4a and 5a illustrate that the formation of the spaced mating and pressing teeth can be achieved, for example, in that a first tooth gap 21a of the internal tooth 21 of the functional element 20 has a larger root circle diameter f than a second tooth gap 21b of the internal tooth 21 of the functional element 21_21a*And the pressing mesh teeth 11a of the external tooth portion 11 of the gear shaft 10 have a tip circle diameter k_11a*Smaller than a root circle diameter f of a first tooth gap 21a of the internal tooth 21 of the functional element 20_21a*And which is greater than or equal to the root circle diameter f of the second tooth gap 21b of the internal tooth 21 of the functional element 20_21b*. Fig. 5a also shows that the guide toothing 11b of the external toothing system 11 of the gear shaft 10 may have an addendum circle diameter k_11b*Smaller than the tip circle diameter k of the pressing teeth 11a of the external tooth system 11 of the gear shaft 10_11a*And/or a root circle diameter f that is smaller than a first tooth gap 21a of the internal tooth 21 of the functional element 10_21a*And/or a root circle diameter f that is smaller than a second tooth gap 21b of the internal tooth 21 of the functional element 20_21b*。

Fig. 6 shows a fifth embodiment of the gear shaft system 100 during assembly.

The embodiment shown in fig. 6 differs from the embodiment shown in fig. 1 to 5b in that the first and second tooth gaps 11a,11b,21a,21 b are not formed in a particularly common tooth section V of the tooth 11,21, but in two different tooth sections V1, V2 of the tooth 11.

In this way, in the case of the embodiment shown in fig. 6, the first tooth recesses 11a are formed in the first tooth section V1 of the external teeth of the toothed shaft 10 and the second tooth recesses 11b are formed in the second tooth section V2 of the external teeth 11 of the toothed shaft 10. The toothless section 12 is arranged between the first tooth section V1 and the second tooth section V2 of the outer toothing 11 of the toothed shaft 10 and in this way likewise adjoins both the first tooth recess 11a and the second tooth recess 11 b.

Similar to the embodiment shown in fig. 3a and 3b, the functional element 20 in the case of the embodiment shown in fig. 6 only has a press-fit toothing 21 a. In contrast to the embodiment shown in fig. 3a and 3b, in the case of the embodiment shown in fig. 6 the number of teeth of the inner toothing 21 of the functional element 20 (i.e. the press-fit toothing 21a) corresponds to the number of first tooth recesses 11a of the first tooth section V1 of the outer toothing 11 of the toothed shaft 10 and likewise to the number of second tooth recesses 11b of the second tooth section V2 of the outer toothing 11 of the toothed shaft 10 and/or the teeth of the inner toothing 21 of the functional element 20 (i.e. the press-fit toothing 11a, respectively) engage in the respective tooth recesses 11a,11b of the outer toothing 11 of the toothed shaft 10, for example in the first tooth recesses 11a of the first tooth section V1 or in the second tooth recesses 11b of the second tooth section V2.

Fig. 6 illustrates that such a gear shaft system 100 can be assembled by first pushing the inner toothing 21 of the functional element 20 onto the outer toothing 11 of the gear shaft 10 in such a way that the press-fit toothing 21a engages into the first toothing recess 11a of the first toothing section V1 of the outer toothing 11 of the gear shaft 10 with a gap-formed mating toothing, and the inner toothing 21 of the functional element 20 can then be pushed up to the toothless section 12 via the outer toothing 11 of the gear shaft 10, in particular via the first toothing section V1 of the outer toothing 11 of the gear shaft 10. Via the toothless section 12, the internal toothing 21 of the functional element 20 can then be rotated about the external toothing 11 of the toothed shaft 10. After the rotation, the inner toothing 21 of the functional element 20 can then be pushed on, in particular onto the outer toothing 11 of the toothed shaft 10, in particular onto the second toothing section V2 of the outer toothing 11 of the toothed shaft 10, in such a way that the press-fit toothing 21a engages in the second toothing recess 11b of the second toothing section V2 of the outer toothing 11 of the toothed shaft 10 and forms a press-fit toothing or a mating toothing without play, in the same direction or in the initial push-up direction a (which can also be referred to as the push-up direction P of the press-fit toothing at this time). The radial positions of the first tooth recess 11a and the second tooth recess 11b can be matched to one another or in particular can be different from one another. By means of this rotation, the installation space can be utilized in different radial spatial directions in the case of the initial push-up and in the case of the subsequent push-up with pressing engagement, as a result of which the assembly can be simplified and in particular also complex systems and/or systems with complex installation space conditions can be assembled.
