Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to 6, it is a schematic structural diagram of a gear with individually detachable teeth according to the present invention. The gear with individually detachable teeth includes a toothed plate 10 and a toothed ring 20 disposed on an outer side wall of the toothed plate 10, and the gear with individually detachable teeth further includes other functional modules, such as lubricating oil, etc., which should be known to those skilled in the art, and will not be described in detail herein.

The fluted disc 10 includes a fluted disc main body 11, and a first mounting hole 12 disposed on an outer side wall of the fluted disc main body 11. The outer contour of the fluted disc main body 11 is circular, and the first mounting holes 12 are arranged on the outer side wall of the fluted disc main body 11 at intervals. A first thread 121 is arranged in the first mounting hole 12, and the first thread 121 is used for improving self-locking performance when being connected with the tooth ring 20.

The tooth ring 20 includes a plurality of convex teeth 21 disposed on the outer sidewall of the fluted disc main body 11, a plurality of concave teeth 22 disposed on the outer sidewall of the fluted disc main body 11, and reinforcing teeth 23 also disposed on the outer sidewall of the fluted disc main body 11. Two buckling strips 211 are arranged on two sides of the length direction of the convex teeth 21, and the length of each buckling strip 211 is the same as that of each convex tooth 21. Two buckling grooves 221 are formed in two sides of the concave tooth 22 in the length direction, and the length of each buckling groove 221 is the same as that of the concave tooth 21. The fastening strips 211 are coupled with the fastening grooves 221, and chamfers are arranged at the edges of the fastening strips, so that the fastening strips are more smooth during assembly. The fastening strips 211 and the fastening grooves 221 are respectively disposed on two sides of the reinforcing teeth 23 in the length direction.

The reinforcing teeth 23 are used for being matched with the convex teeth 21 and the concave teeth 22 to be installed when the sum of the number of the convex teeth 21 and the number of the concave teeth 22 is even and only one tooth vacancy is reserved. It is conceivable that the reinforcing teeth 23 may not be installed in the case where the sum of the numbers of the male teeth 21 and the female teeth 22 is an even number. Specifically, when the sum of the number of the male teeth 21 and the number of the female teeth 22 is even, the tooth ring 20 can be assembled by the male teeth 21 and the female teeth 22 via the snap strips 211 and the snap grooves 221 provided in the male teeth 21 and the female teeth 22. The male, female and stiffening teeth 21, 22, 23 all have a tip end 24 of the same gauge. And the radian of the convex teeth 21, the concave teeth 22 and the reinforcing teeth 23 facing the end surface of the fluted disc main body 11 is the same as the radian of the outer side wall of the fluted disc main body 11. So that both end faces can be completely attached to each other after being assembled with the fluted disc main body 11.

The tooth tip end portion 24 is provided with a plurality of second mounting holes 25 arranged at intervals. The second mounting hole 25 is provided with a second thread 251, and the second mounting hole 25 and the second thread 251 have the same specifications as the first mounting hole 12 and the first thread 121. So that it can be fixed by a long screw. The end of the second mounting hole 25 is provided with a counter bore 252, and when the second mounting hole 25 is fixed with the first mounting hole 12 through a screw, the counter bore 252 enables the nut part of the screw to be flush with or lower than the tooth tip end part 24, and direct meshing of gears cannot be influenced. The second mounting holes 25 are identical to the first mounting holes 12 in specification and number, so that the male teeth, the female teeth and the reinforcing teeth 21, 22 and 23 can be mounted on the fluted disc main body 11, the strength of the fluted disc main body 11 after being mounted is improved through the plurality of second mounting holes 25 arranged in the same row, and the bearable maximum torque range is improved.

When the gear is used, the teeth of the gear which can be independently disassembled and assembled are fixed with the fluted disc main body 11 through the screw connection of the convex teeth 21 and the concave teeth 22, and the buckling strips 211 are matched with the buckling grooves 221 to form the tooth ring 20. When the sum of the total number of the convex teeth 21 and the concave teeth 22 is an even number and only one tooth vacancy is left, the reinforcing teeth 23 can be simultaneously matched with the convex teeth 21 and the concave teeth 22 to be respectively fixed with the buckling strips 211 and the buckling grooves 221, so that the reinforcing teeth and the fluted disc main body 11 form a whole. When one of the teeth of the gear with the separately detachable teeth is damaged and needs to be replaced, a technician only needs to dismount the fastening screw with the damaged tooth, pull the fastening screw out of the tooth ring 20 and insert the replaced tooth with the same specification.

Compared with the prior art, the gear with the independently detachable teeth provided by the invention has the advantages that the teeth on the gear are modularized and are divided into three types of teeth, namely the convex teeth 21, the concave teeth 22 and the reinforcing teeth 23, and the effect of multiple fixation is achieved through the matching of the buckling strip 211 and the buckling groove 221 and the corresponding arrangement of the first mounting hole 12 and the second mounting hole 25. The convex teeth 21 and the concave teeth 22 are matched with each other and arranged on the outer side wall of the fluted disc main body 11, and the reinforcing teeth 23 are used for being matched with the convex teeth 21 and the concave teeth 22 when the sum of the number of the convex teeth 21 and the number of the concave teeth 22 is an even number and only one tooth vacancy is reserved. The gear ring 20 is connected and fixed through the matching of the buckling strips 211 and the buckling grooves 221 and a plurality of mounting holes, so that the bearable torque range is further improved. The gear with the independently-detachable teeth can be used for independently replacing one or more teeth needing to be replaced on the premise of not detaching unnecessary parts, is convenient to detach and high in bearable torque, improves the working efficiency and reduces the maintenance cost.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
