AI Technical Summary
Vibrations generated during the operation of deep groove ball bearings are transmitted to the bearing, affecting its stability and potentially causing damage. Existing technologies are unable to effectively reduce the damage caused by vibration.
A multi-stage damping ring for deep groove ball bearings was designed, including an outer ring and an inner ring. The outer ring is equipped with a buffer assembly and a rubber pad, while the inner ring is equipped with a slot and a mounting slot. The bearing is subjected to two-stage damping through the rubber pad and the buffer assembly. When the vibration is large, the buffer assembly converts kinetic energy into heat energy through friction, thus absorbing the vibration energy.
It effectively reduces the damage caused by bearing vibration and extends the service life of the device. Through the design of multi-stage damping rings, it absorbs and converts the vibration energy of the bearing, thereby improving the stability and service life of the bearing.

DETAILED DESCRIPTION
[0018] The utility model will be further described in detail below with reference to the drawings and specific embodiments.
[0019] Embodiment:
[0020] As Figures 1 to 3 shown, the embodiment provides a multi-stage damping ring special for deep groove ball bearing, which comprises an outer ring 1 and an inner ring 2, the outer ring 1 is arranged outside the inner ring 2 and coaxial with the inner ring 2, the inner wall of the outer ring 1 is uniformly provided with a plurality of buffer assemblies 3 along the circumference, the inward end of the buffer assembly 3 is provided with a rubber pad 4, the inward end of the rubber pad 4 is provided with a clamp block 5, the outer wall of the inner ring 2 is provided with a clamp slot 6 corresponding to the clamp block 5, the clamp block 5 and the clamp slot 6 are detachably connected, and the inner wall of the inner ring 2 is provided with a mounting slot 7 for mounting the bearing.
[0021] The bearing mounted on the inner ring 2 is subjected to two-stage damping by the rubber pads 4 on the inner side and the buffer assemblies 3 on the outer side, so as to reduce the damage caused by the bearing vibration and prolong the service life of the device; when the vibration amplitude of the bearing is small, the vibration energy of the bearing is absorbed by the deformation of each rubber pad 4; when the vibration amplitude of the bearing is large, the vibration energy of the bearing is absorbed by each rubber pad 4 and the buffer assembly 3.
[0022] Further, the buffer assembly 3 comprises a movable rod 8, an adjusting screw 9 and a spring 10, the inner wall of the outer ring 1 is uniformly provided with a plurality of movable holes 11 along the circumference, the direction of the movable hole 11 is along the radial direction of the outer ring 1, the movable rod 8 is slidably connected to the movable hole 11, the end of the movable rod 8 towards the center of the outer ring 1 is provided with a long plate A 12, the long plate A 12 is provided with a rubber pad 4, the end of the movable rod 8 away from the center of the outer ring 1 is provided with a long plate B 13, the outer ring 1 is provided with a movable slot 14 for the long plate B 13, the spring 10 is connected between the side of the movable slot 14 away from the movable hole 11 and the long plate B 13, the axis direction of the spring 10 is parallel to the direction of the movable hole 11, the outer side of the outer ring 1 is provided with a threaded hole 15 leading to the movable slot 14, the threaded hole 15 is threadedly connected with the adjusting screw 9, and the long plate B 13 is provided with a limiting slot 16 for the end of the adjusting screw 9 to extend into.
[0023] When the vibration amplitude of the bearing is large, the vibration that cannot be completely eliminated by the rubber pad 4 is transmitted to the movable rod 8 along the long plate A 12, which drives the movable rod 8 to reciprocate in the movable hole 11, and the kinetic energy is converted into heat energy through the friction between the movable rod 8 and the movable hole 11 during the sliding process, thereby consuming the vibration energy of the bearing; the spring 10, the long plate B 13 and the movable rod 8 are used in combination to keep the rubber pad 4 on the long plate A 12 against the outer wall of the inner ring 2, so that the movable rod 8 can quickly respond when the bearing vibrates and can return to the original position after the vibration of the bearing ends; the length of the end of the adjusting screw 9 extending into the movable slot 14 can be adjusted by rotating the adjusting screw 9, thereby indirectly changing the movable range of the movable rod 8; the longer the length of the adjusting screw 9 extending into the movable slot 14, the smaller the movable range of the movable rod 8.
[0024] Further, the outer end of the adjusting screw 9 is provided with a handle 17.
[0025] The handle 17 can conveniently rotate the adjusting screw 9 for the user.

[0027] Further, the shape of the inward end of the rubber pad 4 is a circular arc shape consistent with the shape of the outer wall of the inner ring 2, and the inward end of the rubber pad 4 is tightly attached to the outer wall of the inner ring 2.
[0028] The rubber pad 4 tightly attached to the outer wall of the inner ring 2 can better absorb the vibration energy of the bearing.
[0029] The working principle and use process of the utility model are as follows:
[0030] The bearing is installed in the mounting groove 7 of the inner ring 2, and the outer ring 1 is installed on the mounting position of the device. When the device is running and the bearing is vibrating, the kinetic energy of the bearing is transmitted to the rubber pad 4 abutting against the inner ring 2 along the inner ring 2. The rubber pad 4 absorbs the kinetic energy by deforming itself. When the vibration amplitude of the bearing is large, the kinetic energy that cannot be converted is transmitted to the movable rod 8 along the long plate A12, drives the movable rod 8 to reciprocate, converts the kinetic energy into heat energy through the friction between the movable rod 8 and the movable hole 11, and further reduces the vibration amplitude of the bearing. The user can change the movable range of the movable rod 8 by adjusting the adjusting screw rod 9. The deeper the adjusting screw rod 9 penetrates into the movable groove 14, the smaller the movable range of the movable rod 8, and the smaller the moving range of the inner ring 2 and the bearing.
[0031] The above is only a specific application example of the utility model, and does not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
