Impact sound and its control method of rolling large models of ball bearings or cylindrical roller bearings under purely radial load and low speed operation, due to the centrifugal force of the rolling small, in the non load rolling will impact the holder or rolling road noise. But with the increase of rotational speed, the noise will disappear. On the rolling control method for impact sound: appropriate reduction of radial clearance, the use of reasonable structure and materials with cage bearings compliance.
A creak and control method for INA bearings creak metal friction sound cylindrical roller bearings are likely to occur in all cases of harsh, mostly in the larger models grease lubricated bearings, the grease base oil on the performance degradation in more easily, almost does not occur under oil lubrication. In addition, more vulnerable in the winter, when under purely radial load, prone to big occasions in a radial clearance, and with different model sizes, easy to occur within a specific speed range, both continuous and intermittent. The outer ring raceway special processing methods can prevent creak appears, when necessary, can choose this kind of bearing, or appropriate INA bearing radial clearance reduction, using high performance greases and improve the rigidity of bearing matching parts. This is the common way of how to better control the bearing noise, we can follow the operation.
