Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.

As shown in fig. 1 and fig. 2, a first embodiment of the present invention mainly discloses an auxiliary meshing system 10 for a multi-stage gear set of an intelligent gas meter gearbox, which at least includes:

a moving member 101 for moving in a direction perpendicular to a rotational plane of the gear in the transmission multi-stage gearset 20;

the self-resetting deformation piece 102 is connected to the moving piece 101 and moves along with the moving piece 101, and the self-resetting deformation piece 102 moves to the upper end face of a gear in the gearbox multi-stage gear set 20 along with the moving piece 101 and is pressed downwards;

an air blowing member 103 provided on one side of the moving member 101 for continuously or intermittently blowing air to generate an air flow directed to one or more gears in the transmission multi-stage gear set 20;

the air flow generated by pressing down the self-resetting deformation piece 102 and the air blowing piece 103 drives the gears of the gearbox multi-stage gear set 20 to mesh.

The auxiliary meshing system 10 for the multi-stage gear set of the intelligent gas meter gearbox is mainly used for meshing the multi-stage gears after the multi-stage gear set of the auxiliary gearbox is installed, and can be arranged after the installation process of the multi-stage gear set 20 of the gearbox.

When the auxiliary meshing system 10 of the gearbox multi-stage gear set of the intelligent gas meter is used, the gearbox multi-stage gear set 20 is conveyed on a conveying track and is installed, when the auxiliary meshing system 10 of the gearbox multi-stage gear set of the intelligent gas meter is reached, conveying is stopped, at the moment, the moving piece 101 drives the self-resetting deformation piece 102 to move, the self-resetting deformation piece 102 moves to the upper end face of an internal gear of the gearbox multi-stage gear set 20 along the direction perpendicular to the rotating face of the internal gear of the gearbox multi-stage gear set 20, the self-resetting deformation piece 102 is continuously pressed down until the self-resetting deformation piece is contacted with the upper end face of the internal gear of the gearbox multi-stage gear set 20, after the self-resetting deformation piece 102 is contacted, the internal gear of the gearbox multi-stage gear set 20 is driven to axially translate along respective gear shafts based on the pressing force of the self-resetting deformation piece 102 or the self-resetting deformation force of the self-resetting deformation, so that the dimensional error that the gears are not installed in place during assembly can be compensated, and each gear can be installed to a proper position on a shaft, the assembly precision of the gears is improved, secondly, when the gears axially translate along respective gear shafts, the gears synchronously generate actions under the driving of the pressure of the self-resetting deformation piece 102 or the self-resetting deformation force thereof, the action can be slight shaking, floating, inclining or rotating, when the gears act, the gear teeth and the gear grooves between the gears can better form inserting matching, thereby realizing the meshing effect mutually, ensuring the meshing position and precision of the gears in the gear set, playing a good auxiliary effect of gear meshing, and the self-resetting deformation piece 102 of the present embodiment has a self-resetting deformation effect, when the gear is pressed, which can be deformed to reduce the rigidity effect on the gear and can increase the contact area with the gear after being deformed, the extrusion force or the self-resetting deformation force can be uniformly dispersed to the contact surface of the gear, the gear deformation caused by local extrusion is avoided, and the integrity of the gear is further ensured; meanwhile, the air flow generated by the air blowing of the air blowing piece 103 is used as the driving force of the gearbox multistage gear set 20, the thrust generated by the air flow drives one or more gears in the gearbox multistage gear set 20 to rotate, in the rotating process, due to the air flow, the acting force between the gears, the gravity action of the gears and the like, the gears can not only rotate under the action of the air flow, but also slightly shake, float, incline or rotate and the like.

It should be noted that:

the self-resetting deformation piece 102 is pressed down and the air blowing piece 103 blows air, and belongs to two actions, wherein the two actions can realize the auxiliary effect of gear engagement, and when the self-resetting deformation piece is used specifically: the two can be separated in sequence, namely the self-resetting deformation piece 102 is pressed down and then the air blowing piece 103 blows air, or the air blowing piece 103 blows air and then the self-resetting deformation piece 102 is pressed down; the two can also operate simultaneously, but because the two can interact with each other, in this embodiment, in order to reduce the interaction, it is preferable that the downward pressure or deformation force of the reset deformation member 102 is much greater than or less than the airflow thrust of the blowing member 103, and one of the two acts is used as the main action, and the other acts as the auxiliary action.

Secondly, in continuous or intermittent blowing: continuous blowing means continuous blowing at a fixed flow rate; or the flow rate is gradually increased or decreased at a fixed rate to continue blowing.

Firstly, the air is continuously blown at a fixed flow rate, namely the air blowing piece 103 continuously blows air at a fixed flow rate, so that continuous and stable air flow can be provided for the gearbox multi-stage gear set 20, further, the action generated by the gears is stable, the gears are more stable in meshing, the meshing speed is high, and the effect is good. Further, the fixed flow rate can be 500-1000 ml/min. Further, the fixed flow rate may be 500ml/min, 550ml/min, 600ml/min, 650ml/min, 700ml/min, 750ml/min, 800ml/min, 850ml/min, 900ml/min, 950ml/min, 1000 ml/min. Specifically, the fixed flow rate is 750 ml/min.

Secondly, the flow is gradually increased or decreased at a fixed rate for continuous blowing, which means that the blowing amount of the blowing piece 103 is gradually increased at a fixed rate for blowing; or the air blowing member 103 blows air by gradually reducing the amount of blown air at a fixed rate.

Wherein, the air blowing piece 103 blows according to a fixed speed gradual increase blowing volume, the air blowing piece 103 blows from zero or an initial blowing volume, and according to fixed speed gradual increase blowing volume until increasing to the maximum blowing volume and stopping or repeating, this mode utilizes the method of gradual increase blowing volume, can blow the gear to unable rotation earlier, but can rock slightly or float, and then mesh the gear of easy meshing in advance, then after the blowing volume increases the gear and begins to rotate, the rotation of adjacent gear is realized through gear rotation to combine above action realization all gears's meshing, this mode gear meshing success rate is higher, but the consuming time is longer.

The air blowing part 103 gradually reduces the air blowing amount according to a fixed speed to blow air, namely the air blowing part 103 blows air from an initial air blowing amount, gradually reduces the air blowing amount according to the fixed speed until the air blowing amount is reduced to the minimum air blowing amount, namely the air blowing part stops or repeats, the method firstly utilizes large air flow to drive the gears to be meshed, the meshing of the gears can be realized on a large scale or the gears with larger dislocation are driven to be meshed, then the air blowing amount is gradually reduced, further, the gears are driven to slightly shake or float through fluctuation caused by air reduction, all the gears are further driven to be meshed, the method has the advantages of high gear meshing success rate and short time consumption, but the gears are easily damaged due to the fact that the initial air blowing amount is large, and the gears are easily damaged, and the gears are damaged.

The fixed rate is a fixed value, which may be 50-300 ml/min. Further, the fixed rate may be 50ml/min, 100ml/min, 150ml/min, 200ml/min, 250ml/min, 300 ml/min. Specifically, the fixed rate is 150 ml/min. The maximum air blowing amount is an upper limit value of the air blowing amount, so that excessive extrusion or deformation of the gear caused by excessive air blowing amount is avoided, and the maximum air blowing amount is preferably not more than 1000 ml/min; similarly, the minimum air blowing amount is a lower limit value of the air blowing amount, so that the situation that all gears cannot be driven to move due to too small air blowing amount and the auxiliary effect is lost is avoided, and the minimum air blowing amount is preferably not less than 500 ml/min.

Immediately above, intermittent blowing means: the air blowing member 103 continuously blows air with a fixed time interval. The interval of the fixed time is that the air blowing piece 101 blows intermittently according to the fixed time as the air blowing interval, and the air blowing mode can be the continuous air blowing mode. Further, the fixed time can be 0.5-2.5 seconds. Further, the fixed time may be 0.5 second, 1 second, 1.5 seconds, 2 seconds, 2.5 seconds. Specifically, the fixed time is 1.5 seconds.

Based on the above blowing modes, the multistage gear set auxiliary meshing system 10 of the intelligent gas meter gearbox of the embodiment can reasonably select the above blowing modes or the combination of any modes to perform gear meshing assistance.

Thirdly, the air flow directed to one or more gears in the gearbox multi-stage gear set 20, i.e. the blowing direction of the blowing element 103, may be: the air flow is relatively concentrated in the blowing direction, all the gears can be driven to move and further meshed in sequence based on the motion of one gear, and the gears are meshed more completely and completely from local to overall and have sequence, and the meshing degree of the gears is high. The first stage or last stage gear is a gear located at the first stage or the last stage of the gearbox multi-stage gear set 20, or in terms of transmission mode, the first stage or last stage gear is a driving transmission gear or an output transmission gear in the gearbox multi-stage gear set 20; the blowing direction may also be: to any number of gears in the transmission multi-stage gearset 20, such as any two gears that need to be meshed. This mode of blowing can drive the action of two at least gears simultaneously, and then utilizes the action of two at least gears to drive a plurality of gear engagement simultaneously, and gear engagement is more quick, but gear engagement unordered nature, the unable engaged condition of screens each other easily appears, and the meshing effect is relatively poor. Furthermore, the blowing direction of the blowing element 103 is directed towards the tooth flanks of one gear of the gearbox multi-stage gearset 20 or towards the meshing of any two gears of the gearbox multi-stage gearset 20. Specifically, the blowing direction of the blowing member 103 is directed to the tooth surfaces on the inner side of the gear grooves of the first stage or the last stage of the gear set 20 of the transmission.

Based on the blowing direction, in practical application, any one mode or a combination mode of the two modes can be selected according to requirements to limit the blowing direction.

Referring to fig. 2, the moving member 101 serves as a moving mechanism, and the moving direction thereof includes at least one direction control structure and a conveying mechanism which move along a direction perpendicular to the rotation plane of the gear in the multi-stage gear set 20 of the transmission, and mainly serves as a self-resetting deformable member 102.

As an optional mode, when the rotation plane direction of the gear in the gearbox multi-stage gear set 20 is the horizontal direction, the moving part 101 can be lifted along the direction perpendicular to the rotation plane direction of the gear in the gearbox multi-stage gear set 20 by using a vertical lifting screw rod, and then the self-resetting deformation part 102 can be directly driven to be pressed down to the upper end face of the gear in the gearbox multi-stage gear set 20 after being lowered. Furthermore, in order to realize the lifting action of the vertical lifting screw rod, the vertical lifting screw rod can be connected with a lifting driving mechanism, and then the automatic lifting of the vertical lifting screw rod is realized. The lifting drive mechanism may be a drive motor, a robot arm, a robot, or the like in this embodiment.

With continued reference to fig. 2, the self-resetting deformable element 102 is an auxiliary element having a deforming force and capable of automatically restoring its shape to an original state, and is driven by the moving element 101 to move so as to press down on the upper end surface of one or more gears in the multi-stage gear set 20 of the transmission, and it may be an inelastic element, and only depends on the pressing force and its own gravity to press the gears, such as cotton, cloth, plastic, blocking pieces, etc., in the multi-stage gear set 20 of the transmission; the elastic element can be a metal or nonmetal sheet, strip or wire, the metal or nonmetal can be plastic, rubber, sponge, memory alloy and the like, and the elastic element can also be an elastic reset structure consisting of a plurality of deformation elements and other mechanisms, such as a spring shifting piece mechanism consisting of a spring and a shifting piece, a brush consisting of elastic bristles and a brush handle and the like.

It should be noted that, for convenience of replacement, the self-resetting deformable element 102 may be detachably connected to the self-resetting deformable element 102, such as by bonding, fastening, clamping, or screwing.

As a preferred structure, the self-resetting deformable element 102 can be selected from self-resetting soft elastic elements, and by virtue of the soft characteristic, when the self-resetting deformable element is in contact deformation with the gearbox multi-stage gear set 20, the self-resetting soft elastic element can be prevented from being rigidly extruded with the gear to damage the gear, the integrity of the gear is well protected, the deformation also belongs to flexible deformation, the deformation force cannot be increased greatly due to the increase of the deformation amount, the gear can be prevented from being damaged due to the excessive extrusion of the gear by the deformation force, and due to the soft characteristic, the deformation can be dispersed to the whole contact surface of the gear by the downward pressure, the gravity or the deformation force after the deformation, so that the local stress is dispersed, the deformation and the distortion caused by the stress concentration are avoided, and the gear is further protected.

Specifically, the self-resetting flexible elastic piece is a brush. The brush hair of brush warp with gear contact back, because the brush head of brush comprises a plurality of tiny brush hairs, and then its and gearbox multistage gear set 20 contact back, can correspond gear structure and gear position and carry out local self-adaptation deformation, thereby can contact and produce different deformation direction with different gears, the deflection, the action that not only can be fine drive corresponds the gear, make different gears produce different action or displacement volume, improve the meshing probability, the reduction that can also maximize is to the damage and the extrusion of gear, fabulous protection gear structure.

As shown in fig. 3, the blowing member 103 is mainly used for blowing air to drive one or more gears in the gearbox multi-stage gear set 20 to engage, and the blowing direction of the blowing member 103 is preferably parallel to the side surfaces of the gears in the gearbox multi-stage gear set 20, that is, the blowing direction is parallel to the side surface of any gear in the gearbox multi-stage gear set 20 and has no included angle, so that the air flow generated by blowing air by the blowing member 103 horizontally points to the gears in the gearbox multi-stage gear set 20, thereby preventing the gears in the gearbox multi-stage gear set 20 from being axially moved and locked with each other due to component forces in other directions caused by the air flow, and avoiding affecting the assembly precision and the engagement effect. The side surfaces of the gear refer to side surfaces on both sides of the gear perpendicular to the central axis of the gear.

As the air blowing structure of the embodiment, the air blowing member 103 preferably uses a capillary tube for blowing air to ensure that the blowing direction and speed can be maintained for a long time after the air is blown out. Further, the capillary tube may be made of a gooseneck to facilitate adjustment of the blowing direction.

In order to better realize the blowing effect of the blowing member 103, the blowing member 103 of the present embodiment is further connected to an air supply system with a flow control assembly. The gas supply system (not shown) of the present embodiment can continuously supply gas to the blowing member 103 and control the flow rate, etc. of the supplied gas by the flow control assembly. Specifically, the flow control component can be a flow valve, a flow rate valve, a regulating valve and the like, and the gas supply system can be a gas pump, a gas cylinder, a gas bag and the like.

As shown in fig. 4, the intelligent gas meter gearbox multistage gear set auxiliary meshing system 10 of the embodiment further includes a lifting assembly 104, and the gas blowing piece 103 is disposed on the lifting assembly 104. The lifting assembly 104 of the embodiment is used for driving the air blowing piece 103 to lift, and then the height of the air blowing piece 103 can be adjusted as required, so that the gear driving requirement can be met.

Specifically, the lifting assembly 104 includes a bracket 1041, a lifting block 1042 connected to the bracket 1041, and the blowing unit 103 is disposed on the lifting block 1042.
