Abstract
Description
Technical Field
[0001] This utility model relates to the field of speed reducer technology, specifically a right-angle speed reducer with a shock absorption mechanism. 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 commonly used as a speed reduction transmission device between the prime mover and the working machine, and plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.
[0003] A Chinese patent (publication number CN220791997U) discloses a speed reducer with a protective structure. When the speed reducer is running and generates vibration, the impact force generated by the vibration is transmitted to the buffer spring rod through an arc-shaped plate on the outer surface of the speed reducer. At this time, the buffer spring rod undergoes elastic deformation, and the buffer spring rod absorbs energy and buffers the transmitted impact force.
[0004] However, the aforementioned design of a speed reducer with a protective structure still has some drawbacks in actual use: when the speed reducer generates strong vibrations, the buffer spring rod may not be able to absorb all the impact force in a timely and effective manner, resulting in the remaining impact force acting between the protective cover and the fixed base. After long-term use, the buffer spring rod has limited buffering capacity, and the connection between the protective cover and the fixed base is affected and prone to cracks, which is not conducive to the stable operation of the speed reducer. Utility Model Content
[0005] The purpose of this invention is to provide a right-angle speed reducer with a shock-absorbing mechanism to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the present invention provides a base and a right-angle reducer disposed on the base. The top of the base is provided with a longitudinal damping component, which includes a first slider slidably disposed on the top of the base. A round rod is fixedly installed on one side of the first slider. There are two first sliders, which are symmetrically disposed on the base with the vertical axis of the base as the center. The two first sliders are fixedly connected by the round rod. A second slider is slidably sleeved on the round rod. A compression spring is fixedly connected to one end of the second slider. There are two second sliders, one of which is fixedly connected to the other end of the compression spring. A mounting plate is fixedly installed at the bottom of the right-angle reducer, and the top of the second slider is movably connected to the bottom of the mounting plate.
[0007] Furthermore, a first damper is fixedly installed on the top of the first slider, the driving end of the first damper is fixedly connected to the bottom of the mounting plate, a first damping spring is sleeved on the outside of the first damper, one end of the first damping spring is fixedly connected to the first slider, and the other end of the first damping spring is fixedly connected to the bottom of the mounting plate.
[0008] Furthermore, the base is also provided with a lateral shock absorption component, which includes a mounting seat disposed on one side of the inner wall of the base, an airbag fixedly installed in the mounting seat, and a push block slidably connected to one side of the mounting seat, the push block being slidably connected to the mounting seat.
[0009] Furthermore, a second damper is fixedly installed on the side of the press block near the first slider, and a second damping spring is sleeved on the outside of the second damper. One end of the second damping spring is fixedly connected to the press block, and the other end of the second damping spring is fixedly connected to the first slider.
[0010] Furthermore, a connecting rod is movably connected to one side of the second slider, a connecting block is fixedly connected to the bottom of the mounting plate, and the other end of the connecting rod is movably connected to the connecting block.
[0011] Furthermore, a groove is provided on the top of the base, and a guide slider is provided at the bottom of the first slider, with the guide slider slidably connected to the groove.
[0012] Furthermore, a fixing plate is fixedly installed on one side of the right-angle reducer, and a bolt is provided on the top side of the fixing plate. The fixing plate is fixedly connected to the mounting plate by the bolt.
[0013] Furthermore, a buffer pad is provided on the side of the fixing plate near the right-angle reducer, and the buffer pad is made of rubber.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the right-angle reducer generates vibration during operation, when buffering longitudinal vibration, the mounting plate is subjected to longitudinal impact force, which drives the connecting block to press down, and the connecting rod causes the second slider to slide and compress the spring. At the same time, the first damping spring deforms and the first damper generates damping force to reduce vibration. When buffering lateral vibration, the first slider slides along the slide groove, and the pressing block compresses the airbag to rebound and reset, thus buffering the lateral vibration energy. By improving the damping and buffering effect in both the lateral and longitudinal directions, the vibration reduction of the right-angle reducer is achieved. Attached Figure Description

[0020] 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.
[0021] Please see Figure 1-4 This utility model provides a technical solution: it includes a base 3 and a right-angle reducer 1 disposed above the base 3. A longitudinal damping component is provided on the top of the base 3. The longitudinal damping component includes a first slider 9 slidably disposed on the top of the base 3. A round rod 4 is fixedly installed on one side of the first slider 9. There are two first sliders 9. The two first sliders 9 are symmetrically disposed on the base 3 with the vertical axis of the base 3 as the center. The two first sliders 9 are fixedly connected by the round rod 4. A second slider 6 is slidably sleeved on the round rod 4. A compression spring 5 is fixedly connected to one end of the second slider 6. There are two second sliders 6. One of the second sliders 6 is fixedly connected to the other end of the compression spring 5. A mounting plate 2 is fixedly installed on the bottom of the right-angle reducer 1. The top of the second slider 6 is movably connected to the bottom of the mounting plate 2.
[0022] In practice, the right-angle reducer 1 is fixed to the top of the mounting plate 2 by the fixing plate 18. When the right-angle reducer 1 is running, the right-angle reducer 1 generates vibration. The longitudinal vibration generated by the right-angle reducer 1 is buffered by the longitudinal vibration damping component. The mounting plate 2 is subjected to longitudinal vibration impact force, which drives the connecting block 8 to press down, causing the ends of the two connecting rods 7 away from the connecting block 8 to move closer to each other. The two second sliders 6 are driven by the connecting rods 7 to slide on the round rod 4. The compression spring 5 between the second sliders 6 is squeezed, and the elastic deformation of the compression spring 5 absorbs and buffers the vibration energy.
[0023] See Figure 3 A first damper 10 is fixedly installed on the top of the first slider 9. The driving end of the first damper 10 is fixedly connected to the bottom of the mounting plate 2. A first damping spring 11 is sleeved on the outside of the first damper 10. One end of the first damping spring 11 is fixedly connected to the first slider 9, and the other end of the first damping spring 11 is fixedly connected to the bottom of the mounting plate 2.
[0024] It should be noted that the number of the first damping spring 11 and the first damper 10 are matched with the number of the first slider 9.
[0025] By setting the first damping spring 11 and the first damper 10, when the mounting plate 2 is pressed down, the first damping spring 11 will generate elastic deformation to absorb the impact force, and the first damper 10 will generate damping force to reduce vibration and buffer the mounting plate 2, thereby reducing the vibration of the right angle reducer 1.
[0026] See Figure 2 and Figure 4 The base 3 is also provided with a transverse shock absorption component, which includes a mounting seat 14 located on one side of the inner wall of the base 3. An airbag 17 is fixedly installed inside the mounting seat 14. A push block 16 is slidably connected to one side of the mounting seat 14. The push block 16 is slidably connected to the mounting seat 14.
[0027] By setting the push block 16 and the mounting base 14, when the push block 16 slides, it squeezes the airbag 17, and the airbag 17 rebounds, causing the push block 16 to reset, thereby buffering the lateral vibration energy of the right angle reducer 1.
[0028] See Figure 2 A second damper 12 is fixedly installed on the side of the button 16 near the first slider 9. A second damping spring 13 is sleeved on the outside of the second damper 12. One end of the second damping spring 13 is fixedly connected to the button 16, and the other end of the second damping spring 13 is fixedly connected to the first slider 9.
[0029] By setting the second damper 12 and the second damping spring 13, when the right-angle reducer 1 generates lateral vibration, the lateral damping component buffers the vibration. When the mounting plate 2 is subjected to lateral impact force, it can drive the first slider 9 to slide laterally on the base 3 along the slide groove 15. When the first slider 9 slides, the second damping spring 13 on one side of the first slider 9 is squeezed, and the second damper 12 generates damping force to reduce vibration and buffer the first slider 9.
[0030] See Figure 3 A connecting rod 7 is movably connected to one side of the second slider 6, and a connecting block 8 is fixedly connected to the bottom of the mounting plate 2. The other end of the connecting rod 7 is movably connected to the connecting block 8.
[0031] By setting the connecting rod 7, the mounting plate 2 is connected to the connecting rod 7 and the second slider 6 through the connecting block 8.
[0032] See Figure 2 The top of the base 3 is provided with a groove 15, and the bottom of the first slider 9 is provided with a guide slider, which is slidably connected to the groove 15.
[0033] By setting the slide groove 15, the first slider 9 can slide within the slide groove 15 on the base 3.
[0034] See Figure 1 A fixing plate 18 is fixedly installed on one side of the right-angle reducer 1. A bolt is provided on the top side of the fixing plate 18, and the fixing plate 18 is fixedly connected to the mounting plate 2 by the bolt.
[0035] It should be noted that the shape of the fixing plate 18 is set as "L" shape, and the right angle reducer 1 is clamped and fixed by the two fixing plates 18.
[0036] The right-angle reducer 1 is fixed by setting two fixing plates 18.
[0037] See Figure 1 A buffer pad is provided on the side of the fixed plate 18 near the right angle reducer 1, and the buffer pad is made of rubber.
[0038] By setting a buffer pad made of rubber, the fixing plate 18 provides buffer protection when fixing the right angle reducer 1, preventing damage to the right angle reducer 1.
[0039] Working principle: When the device is in use, the right-angle reducer 1 is fixed to the top of the mounting plate 2 by the fixing plate 18. When the right-angle reducer 1 is running, the right-angle reducer 1 generates vibration. The longitudinal vibration generated by the right-angle reducer 1 is buffered by the longitudinal vibration damping component. The mounting plate 2 is subjected to longitudinal vibration impact force, which drives the connecting block 8 to press down, causing the ends of the two connecting rods 7 away from the connecting block 8 to move closer to each other. The two second sliders 6 are driven by the connecting rods 7 to slide on the round rod 4. The compression spring 5 between the second sliders 6 is squeezed. The elastic deformation of the compression spring 5 absorbs and buffers the vibration energy. At the same time as the mounting plate 2 is pressed down, the first damping spring 11 will generate elastic deformation to absorb the impact force. The first damper 10 will generate damping force to reduce vibration and buffer the mounting plate 2, thereby reducing the vibration of the right-angle reducer 1.
[0040] When the right-angle reducer 1 generates lateral vibration, the lateral damping component buffers the vibration. When the mounting plate 2 is subjected to lateral impact force, it can drive the first slider 9 to slide laterally on the base 3 along the slide groove 15. When the first slider 9 slides, the second damping spring 13 on one side of the first slider 9 is squeezed, and the second damper 12 generates damping force to reduce vibration and buffer the first slider 9. When the first slider 9 slides, it drives the button 16 to slide in the mounting base 14. When the button 16 slides, it squeezes the air bag 17. The air bag 17 rebounds, causing the button 16 to reset and buffer the lateral vibration energy of the right-angle reducer 1.
