DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0023] Embodiment 1: A shock-absorbing bearing, comprising a bearing body 1 and a damping pad 6. The damping pad 6 is arranged on the outer diameter of the bearing body 1. The vibration amplitude of the bearing body 1 is reduced through the damping pad 6, and the vibration transmission to other components is reduced, improving the stability and reliability of the entire device. At the same time, it also helps to reduce noise. Lock sleeves 2 are arranged at both ends of the bearing body 1. The lock sleeves 2 are used to fix and fasten the bearing body 1 or other components. Exhaust holes 3 are provided on the outer diameter of the bearing body 1 and the damping pad 6. The exhaust holes 3 serve as channels for balancing the internal pressure of the bearing body 1 and are used to discharge the air inside the bearing body 1. Oil injection holes 4 are provided on the outer diameter of the bearing body 1 and the damping pad 6, which are channels for injecting lubricating oil or grease into the bearing body 1. At the same time, oil outlet holes 5 are provided on the outer diameter of the bearing body 1 and the damping pad 6, which are used to discharge the lubricating oil or grease that has aged, deteriorated or mixed with impurities inside the bearing body 1. Four first fixing columns 7 are fixedly installed on the outer diameter of the damping pad 6 and are tightly connected to each other. At the same time, the other ends of the plurality of first fixing columns 7 are all slidably connected to second fixing columns 8. The cooperation between the first fixing columns 7 and the second fixing columns 8 plays a supporting effect. The other ends of the plurality of second fixing columns 8 are fixedly connected to a rubber pad 9, which are tightly connected to each other and the rubber pad 9 has good elasticity and buffering performance. It can play a role in buffering, shock absorption and sound insulation between the bearing body 1 and other components. When the bearing body 1 generates vibration, the rubber pad 9 can absorb part of the vibration energy. At the same time, a bearing support seat 10 is fixedly connected to the outer diameter of the rubber pad 9 and is tightly connected to each other.

[0024] Embodiment 2: The difference between this embodiment and Embodiment 1 is that an annular mounting base 11 is fixedly connected to the outer diameter of the bearing support base 10, and they are tightly connected to each other. Both ends of the annular mounting base 11 are fixedly connected with fixed bases 12, and they are tightly connected to each other. The fixed bases 12 play a supporting role. Installation grooves 13 are formed on the outside of both fixed bases 12, and the formation of the installation grooves 13 facilitates installation. At the same time, mounting bolts 14 are threadedly connected inside the plurality of installation grooves 13, and the mounting bolts 14 facilitate firm installation. Damping rods 15 are fixedly connected to the inner diameters of the plurality of rubber pads 9. The damping rods 15 can effectively reduce the vibration amplitude of the bearing body 1 and the entire device, and improve the stability of the device. A return spring 16 is arranged on the outer diameter of each of the plurality of damping rods 15. When the return spring 16 is deformed under the action of an external force, the return spring 16 can store energy and prompt the relevant components to return to their original positions after the force disappears. The other ends of the plurality of damping rods 15 are fixedly connected to the outer diameter of the damping pad 6, and they are tightly connected to each other. One end of each of the plurality of return springs 16 is fixedly installed on the outer diameter of the damping pad 6, and they are tightly connected to each other. At the same time, the other ends of the plurality of return springs 16 are fixedly installed on the inner diameter of the rubber pad 9, and they are tightly connected to each other.

[0025] Working principle. In actual use, the device first needs to pass multiple mounting bolts 14 through the mounting grooves 13 opened in the two fixed bases 12, and then firmly install the two fixed bases 12. A ring-shaped mounting seat 11 is fixedly installed on the opposite side of the two fixed bases 12, and a bearing support seat 10 is fixedly installed inside the ring-shaped mounting seat 11. The bearing support seat 10 is used for fixed support. A rubber pad 9 is provided on the inner diameter of the bearing support seat 10. The rubber pad 9 has good elasticity and buffering performance. It can play a role in buffering, shock absorption and sound insulation. When the bearing vibrates, the rubber pad 9 can absorb part of the vibration energy. At the same time, multiple second fixing columns 8 are fixedly installed on the inner diameter of the rubber pad 9, and multiple first fixing columns 7 are slidably connected inside the multiple second fixing columns 8. The other ends of the multiple first fixing columns 7 are fixedly connected with damping pads 6. The damping pads 6 are used to absorb and attenuate the vibration and impact energy generated during the operation of the bearing body 1, and the damping pads 6 reduce the vibration amplitude of the bearing body 1, reduce the vibration transmission to other components, improve the stability and reliability of the entire device, and also help to reduce noise. The cooperation between the first fixing column 7 and the second fixing column 8 plays a supporting effect. At the same time, a bearing body 1 is fixedly connected to the inner diameter of the damping pad 6. The bearing body 1 is the core component of the entire device, mainly used to support the mechanical rotating body, reduce the friction coefficient during rotation, and ensure the rotary accuracy of the rotating body. Multiple damping rods 15 and return springs 16 are provided on the outer diameter of the damping pad 6 and the inner diameter of the rubber pad 9. Among them, the multiple damping rods 15 can effectively reduce the vibration amplitude of the bearing body 1 and the entire device, and improve the stability of the device. When the return spring 16 is deformed under the action of an external force, the return spring 16 can store energy and prompt the relevant components to return to their original positions after the force disappears. The cooperation between the damping rod 15 and the return spring 16 achieves the effects of buffering and resetting. At the same time, exhaust holes 3 are opened on the outer diameter of the bearing body 1 and the damping pad 6. The exhaust holes 3 are used to discharge the air inside the bearing body 1. In addition, when the bearing body 1 is running, it can also be used as a channel to balance the pressure inside the bearing body 1. Oil injection holes 4 and oil discharge holes 5 are also opened on the outer diameter of the bearing body 1 and the damping pad 6. The oil injection hole 4 is a channel for injecting lubricating oil or grease into the bearing body 1, and the oil discharge hole 5 is used to discharge the lubricating oil or grease that has aged, deteriorated or mixed with impurities inside the bearing body 1. The cooperation between the above components can disperse the stress received by the bearing body 1 during operation. When there is vibration or impact, the stress will be absorbed by the buffer components and dispersed to a larger area instead of concentrating on a certain local area. This reduces the risk of fatigue damage of the bearing body 1, making the bearing body 1 not easily appear failure forms such as fatigue cracks during long-term use, and this technical solution enables the bearing body 1 to better adapt to various complex working conditions and will not be quickly damaged due to factors such as vibration in a harsh environment.Improve the adaptability of the bearing body 1 to different working conditions, thereby extending its service life.
