Factors influencing the SKF bearing vibration running

1. Cage causing vibrations. Game between cage and rolling elements, cages with poor lubricant performance, the weight of the cage and the cage material shock absorption is poor, often results in abnormal vibration, this vibration of cages, generally considered to be due to sliding friction between the rolling elements and cage-induced self-excited vibration of a.
2. Surface defects caused by vibration. In SKF bearings of both within and outside the roller road surface Shang, even exists some is small of defects, as: crack, and pressure trace or rust,, also will in bearing running Shi caused vibration, and accompanied by similar Yu riveted job Shi issued of with cyclical of noise, if speed must, this vibration of cycle also must, and with speed of reduced, cycle corresponding extended, on ball bearing, as only is steel ball surface exists defects, this vibration will Shi sometimes no, but must is cyclical of.
3. SKF bearing part hardness. When guaranteed/H2>1 ⅲ/H1>1 and h h h ⅲ III, h, and h corresponding to the rolling, the outer and inner rings of hardness), increased stability of bearing vibration characteristics of indicators, and with the increased steel ball hardness in the range HRC56~HRC63, bearing Vibration declining, will also improve the stability of the vibration characteristics.
4. Inner Groove, outer Groove curvature radii. Normally SKF bearing Groove curvature radii values both inside and outside the same Raceway contact stress inside and outside to make closer, should enable the Groove in the outer Groove curvature radii greater than the radius of curvature, which can reduce the bearing noise.
