Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and in particular to a speed reducer with a detachable cover plate. Background Technology

[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is mainly used to match the speed and transmit torque between the prime mover and the working machine or actuator.

[0003] The internal structure of the speed reducer is compact. When manual maintenance is required, disassembling the cover plate is time-consuming and labor-intensive. Traditional speed reducer end covers are usually installed on the top of the speed reducer. For structures located at the bottom of the speed reducer, workers must first disassemble the top structure, making direct maintenance difficult. Furthermore, traditional speed reducers inevitably vibrate during operation. This vibration can easily damage the internal structure and cause the cover plate to collide, generating noise.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-4 The illustrated reducer with a detachable cover includes a housing 1, a first cover 5, a snap-fit ​​mechanism, and a shock-absorbing mechanism. A reduction gear mechanism 10 is housed inside the housing 1. The reduction gear mechanism 10 comprises gears, rolling bearings, and sliding bearings. It achieves speed reduction through multi-stage gear transmission. During gear transmission, according to the law of conservation of energy, the input power and output power are approximately equal. When the speed decreases due to the gear ratio, the torque increases proportionally. Reversal is achieved through the gear type and the arrangement of the transmission shaft. The reduction gear mechanism 10 is used for speed reduction, torque increase, and changing the direction of power. The first cover 5 is movably mounted outside the housing 1. A second cover plate 6 is movably connected to the top of the housing 1. Bolts 11 are threadedly connected between the second cover plate 6 and the housing 1. A snap-fit ​​mechanism is set outside the first cover plate 5 to fix the first cover plate 5. A damping mechanism is set at the bottom of the housing 1 to reduce the damage of vibration to the reduction gear mechanism 10. The damping mechanism protects the housing 1, reduces the vibration amplitude of the reducer, protects the internal structure of the reducer, and reduces noise. Workers can use the snap-fit ​​mechanism to directly remove the first cover plates 5 located on both sides of the housing 1 without removing the second cover plate 6. When the bottom parts of the reducer are damaged, workers can directly perform maintenance without first disassembling the top structure.

[0024] In one aspect, the snap-fit ​​mechanism includes a trapezoidal block 15. A deep groove 8 is formed at the top of the first cover plate 5. A second circular rod 16 is rotatably connected to the inner cavity of the deep groove 8. The trapezoidal block 15 is fixedly sleeved on the middle of the outer wall of the second circular rod 16. A torsion spring 17 is fixedly connected between the outer wall of the trapezoidal block 15 and the inner cavity of the deep groove 8. A second limiting groove 18 is formed at the bottom of the second cover plate 6. The trapezoidal block 15 snaps into the inner wall of the second limiting groove 18. A resilient switch 19 is slidably connected to the top of the second cover plate 6. The resilient switch 19 extends into the second limiting groove 18. The resilient switch 19 can use a spring and a sliding rod; after being pressed, the spring can move... The sliding rod automatically resets. The outer wall of the first cover plate 5 has a pull groove 9. There are two first cover plates 5, which are symmetrically arranged. When installing the first cover plate 5, the worker first installs the first cover plate 5 at the designated positions on both sides of the box body 1. The second cover plate 6 is fixedly connected to the top of the box body 1 by bolts 11. At this time, the trapezoidal block 15 is engaged in the second limiting groove 18. When it is necessary to remove the first cover plate 5, the worker presses the elastic switch 19. The elastic switch 19 pushes the trapezoidal block 15 to move downward until the engagement between the trapezoidal block 15 and the second limiting groove 18 is released. Then, the first cover plate 5 is moved through the pull groove 9 until the first cover plate 5 is removed.

[0025] On the other hand, an elastic mechanism is fixedly provided between the second cover plate 6 and the clamping plate 14. The top of the first cover plate 5 is provided with a first limiting groove 7. The outer wall of the clamping plate 14 abuts against the inner cavity of the first limiting groove 7. The elastic mechanism includes a first circular rod 13, which is fixedly connected to the bottom of the second cover plate 6. The clamping plate 14 is slidably sleeved on the outer wall of the first circular rod 13. A second spring 12 is movably sleeved on the outer wall of the first circular rod 13. After the first cover plate 5 and the second cover plate 6 are fixed, the second spring 12 presses the clamping plate 14, and the outer wall of the clamping plate 14 abuts against the inner wall of the first limiting groove 7. When the reduction gear mechanism 10 vibrates, the collision force between the first cover plate 5 and the second cover plate 6 is reduced under the action of the second spring 12, thus reducing noise.

[0026] Preferably, the damping mechanism includes a hydraulic damper 3, which is fixedly connected to the bottom of the housing 1. A base 2 is fixedly connected to the bottom of the hydraulic damper 3, and a first spring 4 is fixedly connected between the base 2 and the housing 1. When the reducer body is working, the hydraulic damper 3 works with the first spring 4 to dampen the housing 1, greatly reducing the vibration amplitude of the housing 1.

[0027] In specific operation: When installing the first cover plate 5, the worker first installs the first cover plate 5 at the designated positions on both sides of the housing 1, and fixes the second cover plate 6 to the top of the housing 1 with bolts 11. At this time, the trapezoidal block 15 is engaged inside the second limiting groove 18. When it is necessary to remove the first cover plate 5, the worker presses the elastic switch 19. The elastic switch 19 pushes the trapezoidal block 15 to move downward until the engagement between the trapezoidal block 15 and the second limiting groove 18 is released. Then, the first cover plate 5 is moved by the pull groove 9 until it is removed. The second spring 12 squeezes the clamping plate 14. The outer wall of the clamping plate 14 abuts against the inner wall of the first limiting groove 7. When the reduction gear mechanism 10 vibrates, the force of the first cover plate 5 colliding with the second cover plate 6 is reduced under the action of the second spring 12, reducing noise. When the reducer body is working, the hydraulic damping 3 works with the first spring 4 to dampen the vibration of the housing 1, greatly reducing the vibration amplitude of the housing 1.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
