Description

Technical Field

[0001] The utility model relates to the technical field of reduction box gears, in particular to an anti - tooth - breakage structure for reduction box gears. Background Art

[0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. Gears are toothed mechanical parts that can mesh with each other, and the application of gears in transmission has appeared very early. Gears are widely used on reduction boxes.

[0003] Common reduction box gears only include tooth teeth. The driving gear and the driven gear can mesh through the tooth teeth, but lack the functions of anti - tooth - breakage and positioning, cannot ensure the integrity of the tooth teeth and the positioning effect of the driving gear, and are prone to long - term friction and force between the tooth teeth when the driving gear rotates, resulting in tooth - breakage of the tooth teeth, and it is also easy for the driving gear to displace on the driving shaft during rotation and cannot mesh with the driven gear, affecting the service life and normal operation of the driving gear.

[0004] Therefore, aiming at the problem that the above - mentioned reduction box gears lack the functions of anti - tooth - breakage and positioning, and cannot ensure the integrity of the tooth teeth and the positioning effect of the driving gear, it is urgently needed to be solved to improve the use scenario of reduction box gears. Summary of the Utility Model

[0005] In order to overcome the problems of common reduction box gears that lack the functions of anti - tooth - breakage and positioning, cannot ensure the integrity of the tooth teeth and the positioning effect of the driving gear, are prone to long - term friction and force between the tooth teeth when the driving gear rotates, resulting in tooth - breakage of the tooth teeth, and it is also easy for the driving gear to displace on the driving shaft during rotation and cannot mesh with the driven gear, affecting the service life and normal operation of the driving gear.

[0006] The technical solution of the utility model is: an anti - tooth - breakage structure for reduction box gears, including a driving component. The driving component is composed of a driving shaft, a fixing strip and a limiting groove. A fixing strip is welded around the driving shaft. An anti - displacement component is arranged in the middle of the driving component. The anti - displacement component is composed of a driving gear body, a connecting groove, a fixing groove, a connecting rod, a buckle strip, a slot, tooth teeth and an installation groove. The driving gear body is sleeved on the driving shaft, and a number of limiting grooves are equidistantly arranged around the driving shaft corresponding to the position of the driving gear body.

[0007] Preferably, by setting the functions of preventing tooth breakage and positioning, the integrity of the teeth and the positioning effect of the driving gear can be ensured, so as to solve the problems of common reduction box gears. The common reduction box gears only include teeth, and the driving gear and the driven gear can be meshed through the teeth, but lack the functions of preventing tooth breakage and positioning, and cannot ensure the integrity of the teeth and the positioning effect of the driving gear. It is easy to cause long-term friction between the teeth when the driving gear rotates and the teeth are damaged due to force, and it is also easy for the driving gear to displace on the driving shaft during rotation and cannot be meshed with the driven gear, affecting the service life and normal operation of the driving gear.

[0008] Preferably, a connection groove is provided on the side of the driving gear body corresponding to the position of the driving shaft, and a fixing groove is provided on the side of the driving gear body corresponding to the position of the fixing strip. One end of the driving shaft penetrates through the connection groove, and the fixing strip is snapped into the inside of the fixing groove. When the driving shaft rotates, since the fixing strip is snapped into the inside of the fixing groove, the driving gear body is driven to rotate.

[0009] Preferably, four connecting rods are symmetrically arranged on both sides of the driving gear body corresponding to the position of the connection groove. One end of the connecting rod is welded with a buckle strip corresponding to the position of the limiting groove, and a slot is provided at one end of the buckle strip. The buckle strip is snapped into the inside of the limiting groove. When positioning the driving gear body, the inserting rod is inserted into the inside of the slot, and then the buckle strip is pulled to both sides of the driving shaft by the inserting rod. Then, after pushing the driving gear body to the specified position, the inserting rod is pulled out from the inside of the slot. At this time, the buckle strip will reset due to its own elasticity and be snapped into the inside of the fixing groove, realizing the positioning function of the driving gear body and preventing the problem that the driving gear body cannot be meshed with the driven gear due to displacement on the driving shaft during rotation, affecting the normal operation of the driving gear body.

[0010] Preferably, a number of teeth are welded at equal intervals around the driving gear body, and an anti-tooth-breakage component is arranged inside the installation groove. After the driving gear body is installed, the teeth of the driving gear body are meshed with the teeth of the driven gear. When the driving gear body rotates, the driving gear body drives the driven gear to rotate through the meshing between the teeth.

[0011] Preferably, installation grooves are symmetrically provided on both sides of the teeth. The anti-tooth-breakage component is composed of a spring, a connecting strip, a rotating roller, a rubber sleeve and a rounded head. A rounded head is welded at the top of the tooth. When the teeth between the driving gear body and the driven gear are separated, the rounded head at the top of the tooth of the driving gear body will contact the outer wall of the tooth of the driven gear instead of the top of the tooth, reducing friction.

[0012] Preferably, a number of springs are symmetrically welded at equal intervals on both sides of the inner wall of the installation groove. One end of the spring is welded with a connecting strip, and the teeth of the driving gear body are supported by the springs so that the rotating roller can fit with the outer wall of the teeth of the driven gear.

[0013] Preferably, a rotating roller is arranged in the middle of the two connecting bars. The two ends of the rotating roller are respectively movably connected to the sides of the two connecting bars. A rubber sleeve is sleeved on the whole body of the rotating roller. When the teeth of the driving gear body and the driven gear mesh, the teeth on the driving gear body slide on the outer wall of the teeth of the driven gear through the rotating roller, reducing friction and the intensity of force, realizing the function of preventing tooth breakage, and preventing the problem that the teeth of the driving gear are damaged due to long-term friction and force between the teeth during rotation, affecting the service life of the driving gear body.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By setting the functions of preventing tooth breakage and positioning, the integrity of the teeth and the positioning effect of the driving gear can be ensured, so as to solve the problems of common reduction gearbox gears, which only include teeth, the driving gear and the driven gear can mesh through the teeth, but lack the functions of preventing tooth breakage and positioning, and cannot ensure the integrity of the teeth and the positioning effect of the driving gear. It is easy to occur that the teeth of the driving gear are damaged due to long-term friction and force between the teeth during rotation, and it is easy to occur that the driving gear is displaced on the driving shaft during rotation and cannot mesh with the driven gear, affecting the service life and normal operation of the driving gear.

[0016] 2. When positioning the driving gear body, insert the insertion rod into the inside of the insertion slot, then use the insertion rod to pull the buckle strip to both sides of the driving shaft, and then push the driving gear body to the specified position. After that, pull out the insertion rod from the inside of the insertion slot. At this time, the buckle strip will reset due to its own elasticity and snap into the inside of the fixing slot, realizing the positioning function of the driving gear body.

[0017] 3. When the teeth between the driving gear body and the driven gear are separated, the rounded head at the top of the teeth of the driving gear body will contact the outer wall of the teeth of the driven gear instead of the top of the teeth, reducing friction. When the teeth between the driving gear body and the driven gear mesh, the teeth of the driving gear body are supported by the spring so that the rotating roller can fit with the outer wall of the teeth of the driven gear. The teeth on the driving gear body slide on the outer wall of the teeth of the driven gear through the rotating roller, reducing friction and the intensity of force, realizing the function of preventing tooth breakage.

[0023] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Please refer to Figures 1-4 , the present utility model provides an embodiment: an anti-tooth-breaking structure for a reduction gearbox gear, including a driving component 1, the driving component 1 is composed of a driving rotating shaft 11, a fixed strip 12 and a limiting groove 13.

The anti-shifting component 2 is composed of a driving gear body 21, a connecting groove 22, a fixed groove 23, a connecting rod 24, a buckle strip 25, a slot 26, a tooth 27 and an installation groove 28. The driving gear body 21 is sleeved on the driving rotating shaft 11, and a number of limiting grooves 13 are arranged at equal intervals around the driving rotating shaft 11 corresponding to the position of the driving gear body 21.

[0025] Please refer to Figures 1-4, in this embodiment, a connection groove 22 is provided on the side of the driving gear body 21 corresponding to the position of the driving rotating shaft 11, and a fixing groove 23 is provided on the side of the driving gear body 21 corresponding to the position of the fixing strip 12. One end of the driving rotating shaft 11 penetrates through the connection groove 22, and the fixing strip 12 is snapped into the inside of the fixing groove 23. When positioning the driving gear body 21, the insertion rod is inserted into the inside of the insertion slot 26, and then the snap strip 25 is pulled towards both sides of the driving rotating shaft 11 through the insertion rod. Then, after pushing the driving gear body 21 to the designated position, the insertion rod is withdrawn from the inside of the insertion slot 26. At this time, the snap strip 25 will reset due to its own elasticity and snap into the inside of the fixing groove 23. When the teeth 27 between the driving gear body 21 and the driven gear are separated, the rounded head 35 at the top of the teeth 27 of the driving gear body 21 will contact the outer wall of the teeth 27 of the driven gear instead of the top of the teeth 27, reducing friction. When the teeth 27 between the driving gear body 21 and the driven gear are engaged, the teeth 27 of the driving gear body 21 enable the rotating roller 33 to fit with the outer wall of the teeth 27 of the driven gear through the support of the spring 31. The teeth 27 on the driving gear body 21 slide on the outer wall of the teeth 27 of the driven gear through the rotating roller 33, reducing friction and the force intensity, and completing the work of preventing tooth breakage and positioning the driving gear body 21.

[0026] Please refer to Figures 1-4, in this embodiment, four connecting rods 24 are symmetrically arranged at positions on both sides of the driving gear body 21 corresponding to the connecting grooves 22. A snap strip 25 is welded at one end of the connecting rod 24 corresponding to the position of the limiting groove 13. A slot 26 is formed at one end of the snap strip 25. The snap strip 25 is snapped into the inside of the limiting groove 13. A number of teeth 27 are welded at equal intervals around the driving gear body 21. An anti-tooth-breakage component 3 is arranged inside the installation groove 28. Installation grooves 28 are symmetrically formed on both sides of the teeth 27. The anti-tooth-breakage component 3 is composed of a spring 31, a connecting strip 32, a rotating roller 33, a rubber sleeve 34 and a rounded head 35. A rounded head 35 is welded at the top of the tooth 27. A number of springs 31 are symmetrically welded at equal intervals on both sides of the inner wall of the installation groove 28. One end of the spring 31 is welded with a connecting strip 32. A rotating roller 33 is arranged between the two connecting strips 32. Both ends of the rotating roller 33 are movably connected to the sides of the two connecting strips 32. A rubber sleeve 34 is sleeved around the rotating roller 33. When positioning the driving gear body 21, the insertion rod is inserted into the slot 26, and then the snap strip 25 is pulled to both sides of the driving rotating shaft 11 through the insertion rod. Then, after pushing the driving gear body 21 to the designated position, the insertion rod is pulled out of the slot 26. At this time, the snap strip 25 will reset due to its own elasticity and snap into the inside of the fixing groove 23. When the teeth 27 between the driving gear body 21 and the driven gear are separated, the rounded head 35 at the top of the tooth 27 of the driving gear body 21 will contact the outer wall of the tooth 27 of the driven gear instead of the top of the tooth 27, reducing friction. When the teeth 27 between the driving gear body 21 and the driven gear are engaged, the teeth 27 of the driving gear body 21 make the rotating roller 33 able to fit the outer wall of the teeth 27 of the driven gear through the support of the spring 31. The teeth 27 on the driving gear body 21 slide on the outer wall of the teeth 27 of the driven gear through the rotating roller 33, reducing friction and the stress intensity, realizing the functions of anti-tooth-breakage and positioning of the driving gear body 21, preventing the driving gear body 21 from shifting on the driving rotating shaft 11 and being unable to mesh with the driven gear when the driving gear body 21 rotates, and preventing the teeth 27 from being damaged due to long-term friction and stress between the teeth 27 when the driving gear rotates, which affects the normal operation and service life of the driving gear body 21.

[0027] When working, insert the insertion rod into the inside of the slot 26, use the insertion rod to pull the buckle strip 25 to both sides of the driving rotating shaft 11, penetrate one end of the driving rotating shaft 11 through the connecting slot 22, and snap the fixing strip 12 into the inside of the fixing slot 23. Then, after pushing the driving gear body 21 to the designated position, pull out the insertion rod from the inside of the slot 26. At this time, the buckle strip 25 will reset due to its own elasticity and snap into the inside of the fixing slot 23. After the driving gear body 21 is installed, mesh the teeth 27 of the driving gear body 21 with the teeth 27 of the driven gear. When the driving gear body 21 rotates, the driving gear body 21 drives the driven gear to rotate through the meshing between the teeth 27. When the teeth 27 between the driving gear body 21 and the driven gear are separated, the rounded head 35 at the top of the teeth 27 of the driving gear body 21 will contact the outer wall of the teeth 27 of the driven gear instead of the top of the teeth 27 to reduce friction. When the teeth 27 between the driving gear body 21 and the driven gear are meshed, the teeth 27 of the driving gear body 21 enable the rotating roller 33 to fit against the outer wall of the teeth 27 of the driven gear through the support of the spring 31. The teeth 27 on the driving gear body 21 slide on the outer wall of the teeth 27 of the driven gear through the rotating roller 33, reducing friction and the stress intensity, and achieving the functions of preventing tooth breakage and positioning the driving gear body 21.

[0028] Through the above steps, by setting the functions of preventing tooth breakage and positioning, the integrity of the teeth 27 and the positioning effect of the driving gear can be ensured, so as to solve the problems of common reduction gearbox gears that only include the teeth 27, the driving gear and the driven gear can be meshed through the teeth 27, but lack the functions of preventing tooth breakage and positioning, cannot ensure the integrity of the teeth 27 and the positioning effect of the driving gear, and are prone to long-term friction and stress between the teeth 27 when the driving gear rotates, resulting in tooth breakage of the teeth 27, and it is also easy for the driving gear to displace on the driving rotating shaft 11 during rotation and fail to mesh with the driven gear, affecting the service life and normal operation of the driving gear.

[0029] The above has described in detail the embodiments of the present invention in conjunction with the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
