[0002] A bearing outer ring embedded vibration damping ring is a mechanical component used to reduce vibration and noise, typically installed between the bearing outer ring and its supporting components. Its main function is to absorb or isolate vibration, reducing vibrations caused by mechanical operation or external impacts, ensuring smooth equipment operation, and extending equipment lifespan.
[0003] Existing bearing outer ring embedded vibration damping rings are mainly rubber damping rings. In use, the damping ring is installed inside the bearing outer ring on both sides of the cage so that the radial load on the bearing during use can be reduced by the elastic buffering performance of the damping ring itself.
[0004] While existing bearing outer ring embedded vibration damping rings can buffer and dampen the radial load on the bearing during use, in actual use, relying solely on the elastic properties of the rubber ring type bearing outer ring embedded vibration damping ring for vibration damping is prone to excessive deformation and damage when the bearing is subjected to large radial loads, thus shortening its service life. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a bearing outer ring embedded vibration damping ring structure with good vibration damping performance and long service life.
[0006] The above-mentioned objective of this application is achieved through the following technical solution: A bearing outer ring embedded damping ring structure includes a bearing outer ring, an inner bearing ring disposed inside the outer ring, a cage installed between the inner and outer rings, bearing balls installed within the cage, and two damping rings symmetrically mounted on either side of the cage between the outer and inner rings. Each damping ring includes a clamping head, a clamping groove, a sliding column, a damping ring pad, a damping telescopic rod, a damping spring, a sliding hole, a support ring, and support balls. The support ring is installed inside the outer ring of the bearing. On one side of the cage, the support ball is mounted on the inner wall of the support ring and contacts the outer ring of the bearing. The damping ring pad is mounted between the outer wall of the support ring and the inner ring of the bearing. The sliding hole is formed on the outer wall of the support ring. The sliding column is mounted in the sliding hole. The damping spring is mounted between the sliding hole and the sliding column. The damping telescopic rod is mounted inside the damping spring. The locking head is mounted on the end of the sliding column opposite to the sliding hole. The locking groove is formed on the outer ring of the bearing and mates with the locking head.
[0007] Optionally, the support ring, the sliding column, and the clamp are all made of chromium steel, and the sliding column is welded to the clamp.

[0015] In summary, this application includes at least one of the following beneficial technical effects: This invention involves installing a damping ring body on both sides of the cage between the outer and inner rings of the bearing. This damping ring body consists of a clamping head, a clamping groove, a sliding column, a damping ring pad, a damping telescopic rod, a damping spring, a sliding hole, a support ring, and support balls. During use, the bearing can utilize the elastic properties of the damping ring pad itself to initially dampen the radial load on the bearing.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.
[0019] To better understand the technical solutions presented in the embodiments of this application, the existing bearing outer ring embedded vibration damping ring structure and its working principle will be introduced first.
[0020] Existing bearing outer ring embedded vibration damping rings are mainly rubber damping rings. In use, the damping ring is installed inside the bearing outer ring on both sides of the cage so that the radial load on the bearing during use can be reduced by the elastic buffering performance of the damping ring itself.
[0021] Please see Figures 1-4 This application discloses a bearing outer ring embedded damping ring structure, comprising a bearing outer ring 1, an inner ring 2 disposed inside the outer ring 1, a cage 3 installed between the inner ring 2 and the outer ring 1, and bearing balls 4 installed within the cage 3. The outer ring 1, inner ring 2, cage 3, and bearing balls 4 constitute the main structure of the bearing. Two damping rings 5 are symmetrically installed on both sides of the cage 3 between the outer ring 1 and inner ring 2. The damping rings 5 dampen the bearing and also seal it. Each damping ring 5 includes a clamp 51, a clamping groove 52, a sliding column 53, a damping ring pad 54, and a damping telescopic rod 5. 5. A damping spring 56, a sliding hole 58, a support ring 59, and a support ball 57. The support ring 59 is installed on the inner side of the outer ring 1 of the bearing and on one side of the cage 3. The support ball 57 is installed on the inner wall of the support ring 59 and contacts the outer ring 1 of the bearing. The damping ring pad 54 is installed between the outer wall of the support ring 59 and the inner ring 2 of the bearing. The sliding hole 58 is opened on the outer wall of the support ring 59. The sliding column 53 is installed in the sliding hole 58. The damping spring 56 is installed between the sliding hole 58 and the sliding column 53. The damping telescopic rod 55 is installed inside the damping spring 56. The clamp 51 is installed on the end of the sliding column 53 opposite to the sliding hole 58. The clamping groove 52 is opened on the outer ring 1 of the bearing and mates with the clamp 51.
[0022] Specifically, when the damping ring 5 is installed on the outer ring 1 and inner ring 2 of the bearing, and the bearing is subjected to a large radial load, the damping ring pad 54 will undergo radial deformation, thereby initially buffering and damping the radial load on the bearing. At the same time as the damping ring pad 54 deforms, the sliding column 53 will be pressed into the sliding hole 58 by means of the clamp 51. While the sliding column 53 is pressed into the sliding hole 58, the damping spring 56 will be compressed, and the damping telescopic rod 55 will retract. In order to further buffer the radial load on the bearing with the damping spring 56 and the damping telescopic rod 55, the damping ring 5 will be further buffered, effectively reducing the risk of damage due to excessive deformation, and extending the service life of the damping ring 5.
[0023] Please see Figures 1-3 The support ring 59, the sliding column 53, and the clamp head 51 are all made of chrome steel, and the sliding column 53 is welded to the clamp head 51.
[0024] As one implementation method, the chrome steel support ring 59, slide column 53 and clamp head 51 have good structural strength, so that the support ring 59, slide column 53 and clamp head 51 will not be easily deformed or damaged during use. Welding the slide column 53 to the clamp head 51 can ensure that the clamp head 51 moves and adjusts synchronously with the clamp column.
[0025] Please see Figures 1-3 The vibration damping ring pad 54 is bonded to the outer wall of the support ring 59, and the vibration damping ring pad 54 is made of rubber.
[0026] As one implementation method, the vibration damping ring pad 54 can utilize the elastic properties of its own material to provide initial buffering and vibration reduction for the bearing when subjected to radial load.
[0027] Please see Figures 1-3 There are no fewer than six sliding holes 58. The sliding holes 58 are arranged in a ring on the outside of the support ring 59, and the sliding holes 58 are blind holes.
[0028] As one implementation method, the sliding hole 58 is mainly used to provide a certain space for the sliding column 53 to slide. At the same time, the opening end of the sliding hole 58 is a constricted structure, which can prevent the sliding column 53 from sliding out.
[0029] Please see Figures 1-3 The sliding column 53 corresponds one-to-one with the sliding hole 58, and the sliding column 53 and the sliding hole 58 are in sliding fit.
[0030] As one implementation method, the sliding column 53 is mainly used to realize the synchronous movement and installation of the clamp 51 to ensure the reliable installation of the damping ring 5 between the inner ring 2 and the outer ring 1 of the bearing. At the same time, when the bearing is subjected to radial load, the sliding column 53 can slide into the sliding hole 58 with the help of the clamp 51.
[0031] Please see Figures 1-3One end of the damping spring 56 is welded to the sliding hole 58, and the other end of the damping spring 56 is welded to the sliding column 53.
[0032] In one implementation, the damping spring 56 is compressed into the sliding hole 58 after being pushed by the sliding column 53, so that the sliding column 53 can be reset after the force on the sliding column 53 disappears.
[0033] Please see Figures 2-3 The telescopic part of the damping telescopic rod 55 is welded to the sliding column 53, and the fixed part of the damping telescopic rod 55 is welded to the sliding hole 58.
[0034] As one implementation method, the damping telescopic rod 55 mainly uses the sliding resistance between its telescopic part and the fixed part to offset the radial load on the bearing, thereby working with the damping spring 56 to achieve the purpose of secondary buffering and vibration reduction.
[0035] Please see Figures 2-3 The vibration damping ring pad 54 has a pre-drilled through hole at the part where it mates with the sliding column 53, and the sliding column 53 passes through the pre-drilled through hole on the ring pad.
[0036] As one implementation, the reserved through hole on the vibration damping ring pad 54 ensures that the slide pin 53 can be easily passed through by pressing when the vibration damping ring pad 54 is installed on the support ring 59. The size of the through hole is smaller than the diameter of the clamp head 51, ensuring reliable installation of the vibration damping ring pad 54 on the support ring 59. At the same time, it ensures convenient exposure of the clamp head 51 on the slide pin 53, so as to facilitate convenient clamping and engagement of the clamp head 51 with the clamping groove 52.
[0037] Please see Figure 1 and Figure 4 The mounting groove 52 is distributed in a ring on the outer ring 1 of the bearing, and the mounting groove 52 extends into the inner part of the outer ring 1 of the bearing. The mounting groove 52 is connected to the clamp head 51 by an interference fit.
[0038] In one implementation, when installing the support ring 59 between the outer ring 1 and the inner ring 2 of the bearing, the outer ring 1 and the inner ring 2 of the bearing are first assembled and laid flat with the opening side of the mounting groove 52 on the outer ring 1 facing upward. Then, the clip 51 on the support ring 59 is aligned with the opening of the mounting groove 52 and inserted into the mounting groove 52 with an interference fit. This ensures that the support ring 59 is reliably installed between the outer ring 1 and the inner ring 2 of the bearing. After installation, the support balls 57 on the inner side of the support ring 59 are in contact with the outer wall of the inner ring 2 of the bearing, so that when the inner ring 2 of the bearing rotates, the support ring 59 is placed to rotate with the inner ring 2 of the bearing by means of the rolling of the support balls 57.
[0039] The specific working principle is as follows: First, assemble the bearing outer ring 1, cage 3, bearing balls 4, and bearing inner ring 2. Then, lay the bearing flat and insert the locking head 51 on the support ring 59 into the locking groove 52 to lock it in place. This achieves the installation of the damping ring 5 between the bearing outer ring 1 and the bearing inner ring 2, allowing the bearing to be put into use. During use, when the bearing is subjected to a large radial load after the damping ring 5 is installed on the bearing outer ring 1 and bearing inner ring 2, the damping ring pad 54 will undergo radial deformation. This provides initial buffering and vibration reduction for the radial load on the bearing. As the damping ring pad 54 deforms, the chuck 51 presses the slide column 53 into the slide hole 58. While the slide column 53 is being pressed into the slide hole 58, the damping spring 56 is compressed, and the damping telescopic rod 55 retracts. This further buffers the radial load on the bearing by working together with the damping spring 56 and the damping telescopic rod 55, effectively reducing the risk of damage due to excessive deformation of the damping ring 5 and extending its service life.
[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
