Vibration special bearings and ordinary bearings have certain differences in performance, structure and manufacturing technology.
1. The same application is better than traditional bearings, such as electric motors, alternators and general-purpose machinery, which require smaller outer diameter and radial dimensions, but require a certain vibration absorption capacity.
2. The internal design of the bearing is special, which can reduce the vibration amplitude and shift the vibration frequency of the bearing.
3. The vibration resistant special bearing design allows it to work under bad conditions. Such as high frequency, high speed, heavy load and poor working environment.
4. The contact between the rolling elements and the inner and outer ring raceways is good and uniform, and the rolling contact fatigue life of the bearing is increased.
5. The interference between the inner and outer rings of the bearing can be reduced.
6. Compared with traditional bearings, the contact fatigue life of vibration bearings is improved, and their vibration resistance and noise reduction capabilities are improved.
7. The bearing rings are made of special material, and their production process is very special.
8. The contact angle of the bearing rolling elements and the raceway of the raceway is different from that of the traditional bearing. Depending on the purpose, it can be designed as an angular contact or a radial contact bearing.
9. The inner and outer rings are specially heat treated to increase fatigue strength and prevent fracture.
10. Compared with traditional bearings, the internal structure of vibration bearings is special and their advanced manufacturing technology is also different.
11. The surface of the bearing raceway is a super mirror surface, which can reduce the contact area and improve the service life.
12. The cage is usually made of advanced composite material.
13. The cage of the bearing is also specially designed to limit the amount of elastic deformation and improve the dynamic stiffness of the bearing.
14. The inner ring of the bearing may be provided with an oil groove or a circular groove or a chamfered edge to facilitate the supply of lubricant.
15. The inner and outer rings of the bearing may be indented in the radial direction to improve their radial stiffness and restrict the displacement of the bearing.
16. The bearing may also be provided with an end plate to improve its radial fatigue life.
17. The design of bearing is different from that of traditional bearing, which makes it have high accuracy, good static and dynamic characteristics, and meet the requirement of bearing under special working conditions.
18. Compared with traditional bearings, the high-precision manufacturing processes of vibration-resistant special bearings make them have high quality and low noise.
In summary, the structure of vibration-resistant special bearing is different from that of traditional bearing. It has special requirements in terms of materials, manufacture technology and dimensions. Due to its special design and high-precision manufacturing technology, it has good anti-vibration performance, radial stiffness and fatigue life, and is suitable for use in special environment.
