Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and more specifically, to a simple anti-vibration split bearing structure. Background Technology

[0002] Vibration is inevitable during the operation of many mechanical devices, and it can adversely affect bearings. In a vibrating environment, the internal components of conventional bearings are easily impacted, leading to accelerated wear, increased noise, and even premature failure. Complex and expensive vibration-resistant bearing solutions are not suitable, especially for small equipment or cost-sensitive applications.

[0003] Some existing simple bearings lack effective vibration resistance measures when facing vibration conditions. For example, their cage structure is simple and cannot stably maintain the position of the rolling elements under vibration and impact, which can easily cause collisions and misalignment between the rolling elements, thus affecting the normal operation of the bearing. To address this, we designed a simple vibration-resistant split bearing structure. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a simple anti-vibration split bearing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple anti-vibration split bearing structure, including an outer bearing ring and an inner bearing ring, wherein the outer bearing ring is sleeved outside the inner bearing ring, and a bearing cage is provided between the outer bearing ring and the inner bearing ring. The bearing cage is provided with multiple pockets spaced apart, and each pocket contains a ball. Multiple rubber protrusions are fixed on both the outer and inner walls of the bearing cage.

[0006] As a preferred embodiment of this invention, the bearing cage is made of polyoxymethylene.

[0007] As a preferred embodiment of this utility model, the inner wall of the bearing inner ring is provided with an inner annular groove, an inner rubber ring is placed on the inner wall of the bearing inner ring, and an inner limiting rubber ring is fixed on the outer wall of the inner rubber ring, with the inner limiting rubber ring inserted into the inner annular groove.

[0008] As a preferred embodiment of this utility model, the outer ring of the bearing has an outer annular groove, an outer rubber ring is placed on the outer ring of the bearing, an outer limiting rubber ring is fixed on the inner wall of the outer rubber ring, and the outer limiting rubber ring is inserted into the outer annular groove.

[0009] As a preferred embodiment of this utility model, the inner wall of the bearing outer ring and the outer wall of the bearing inner ring are provided with multiple annular grooves, and the annular grooves are filled with damping rubber rings.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. When the bearing is subjected to vibration and impact, the multiple rubber protrusions on the outer and inner walls of the bearing cage will come into contact with the inner wall of the outer ring of the bearing or the outer wall of the inner ring of the bearing and produce elastic deformation, thereby buffering the vibration energy, reducing the rigid collision between the bearing cage and the outer ring, avoiding damage to the cage due to vibration, and also effectively suppressing the movement of the rolling elements in the pocket.

[0012] 2. The overall structure of this utility model is simple, requiring no complex processing technology or expensive materials, which effectively reduces manufacturing costs and makes it suitable for cost-sensitive applications. Attached Figure Description

[0018] 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.

[0019] like Figures 1 to 3As shown, this utility model provides a simple anti-vibration split bearing structure, including an outer bearing ring 1 and an inner bearing ring 2. The outer bearing ring 1 is fitted over the inner bearing ring 2. A bearing cage 3 is provided between the outer bearing ring 1 and the inner bearing ring 2. The bearing cage 3 has multiple pockets spaced apart. The size and shape of each pocket are precisely matched to the ball 4 to ensure that the ball 4 can be stably placed in the pocket. All pockets contain ball 4. Multiple rubber protrusions 9 are fixed on the outer and inner walls of the bearing cage 3. When the bearing is subjected to vibration impact, the multiple rubber protrusions 9 on the outer and inner walls of the bearing cage 3 will contact the inner wall of the outer bearing ring 1 or the outer wall of the inner bearing ring 2 and generate elastic deformation, thereby buffering the vibration energy, reducing the rigid collision between the bearing cage 3 and the outer ring, and preventing the cage from being damaged by vibration.

[0020] Among them, the bearing cage 3 is made of polyoxymethylene, which has good wear resistance, self-lubrication and a certain degree of toughness.

[0021] The bearing inner ring 2 has an inner annular groove on its inner wall, and an inner rubber ring 6 is placed on the inner wall of the bearing inner ring 2. An inner limiting rubber ring 8 is fixed on the outer wall of the inner rubber ring 6, and the inner limiting rubber ring 8 is inserted into the inner annular groove. The inner rubber ring 6 can be horizontally limited by the inner limiting rubber ring 8 inserted into the inner annular groove, and the bearing inner ring 2 can be buffered and protected by the inner rubber ring 6.

[0022] The outer ring 1 of the bearing has an outer annular groove on its outer wall. An outer rubber ring 5 is placed on the outer wall of the outer ring 1. An outer limiting rubber ring 7 is fixed on the inner wall of the outer rubber ring 5 and is inserted into the outer annular groove. The outer limiting rubber ring 7 can be inserted into the outer annular groove to provide horizontal fiber support to the outer rubber ring 5. The outer rubber ring 5 can provide buffer protection for the outer ring 1 of the bearing.

[0023] The bearing outer ring 1 and the bearing inner ring 2 are provided with multiple annular grooves, and the annular grooves are filled with damping rubber rings 10. When the bearing vibrates, the vibration energy is consumed by the viscoelastic deformation of the damping rubber rings 10, thereby further improving the vibration resistance of the bearing.

[0024] The working principle and usage process of this utility model are as follows: When the bearing is subjected to vibration and impact, multiple rubber protrusions 9 on the outer and inner walls of the bearing cage 3 will contact the inner wall of the outer ring 1 or the outer wall of the inner ring 2 and generate elastic deformation, thereby buffering the vibration energy, reducing the rigid collision between the bearing cage 3 and the outer ring, avoiding damage to the cage due to vibration, and also effectively suppressing the movement of the rolling elements in the pocket. The overall structure of the high-performance bearing is simple, requiring no complex processing technology and expensive materials, effectively reducing manufacturing costs, and is suitable for cost-sensitive application scenarios.
