SKF bearing in itself does not generate noise. We usually feel a "noise" is in fact directly or indirectly with the surrounding structure vibration of sound effects. Noise is the propagation of vibrations in the air by the results of the human auditory system.
It is many times the noise problem may be considered as vibration problems involving the entire application. Number of loaded rolling elements and exciting changes when a roller bearing is a radial load in, its bearing load of scroll amount may vary slightly in the running, namely: 2-3-2-3 .... It has caused the offset direction of load. The resulting vibration is inevitable, but can be mitigated through axial preload, load all the rolling
1) bearing design parameters: include rings of bearing rolling element number, wall thickness and clearance.
2) bearing parts manufacturing errors: including the SKF bearing raceways and rolling elements of surface roughness, crossing the line and the circle of difference. A large number of experimental studies have shown that, waviness on roller bearing vibration effect dominates, and influence of surface roughness and roundness is relatively small.
3) bearing operating conditions: SKF bearings in operation process, load, speed, lubrication on bearing vibration effects of maximum three.
4) bearing installation parameters: roller bearing with shaft and housing seat in favour of compatibility, installation and other factors also have an effect on bearing vibration.
Part between the bearing ring and the bearing seat or shaft key to cope with the case, is likely to match shape and deformation of adjacent parts. If there is distortion, may produce vibrations during operation. Therefore, transmission shafts and machined to the tolerances required are important. Partially damaged due to handling or installation errors and a few roller bearing raceways and rolling elements may be damaged. Running, scroll past the damaged bearing component generates a specific vibration frequency. Vibration frequency analysis of SKF bearings can identify damaged parts. Vibration behavior of applications in many applications, the stiffness and rigidity of the structure around the same. Because of this feature, as long as the proper selection of SKF bearings (including preload and clearance) and its application in the configuration, it is possible to reduce vibrations in the application.
