Four factors that cause vibration in the operation of FAG Bearings

FAG bearings in itself does not produce noise. We usually feel the "noise" in fact, directly or indirectly, with the surrounding structure of the vibration of the sound effect. The noise is the result of the spread of vibration in the air by the feelings of the human auditory system.
This is the noise problem in many cases can be considered as related to the vibration of the entire application. Arising as a result of the loaded rolling element number of changes in excitation when a radial load to load on a bearing, load bearing rolling element number in the operation of a slight change in :2-2-3 ... This has led to the offset of the load direction. The resulting vibration is inevitable, but through the axial pre-load to reduce the load at all rolling element
1) bearing design parameters: bearing the number of rolling bodies, the ferrule wall thickness, and clearance.
2) the bearing parts of the manufacturing error: FAG bearing raceway and rolling element surface roughness, the transition pattern degrees and roundness difference. A large number of experimental studies have shown that the influence of the waviness of the bearing vibration is dominated by relatively small surface roughness and roundness.
3) bearing the working conditions: FAG bearings during operation, load, speed, lubrication condition, three aspects of the bearing vibration maximum.
4) bearing installation parameters: bearing and shaft and bearing with the installation bias factors also affect the vibration of the bearing.
The wave of components in the case of the close tie between the bearing ring and the bearing or drive shaft, the ring may be deformed shape to match adjacent parts. If the deformation, in operation it may lead to vibration. Therefore, the seat and the shaft machined to the required tolerance is very important. Local damage due to the operation or installation errors, the small part of the bearing raceway and rolling element may be damaged. Running, rolling across the damaged bearing components will generate a specific vibration frequency. The frequency analysis can identify the FAG bearing components damaged. The vibration behavior of applications in many applications, the stiffness and the stiffness of the surrounding structures. Because of this characteristic, correctly select FAG bearings (including pre-load and clearance) and its configuration in the application, it is possible to reduce vibration applications.
