Raceway sound source is produced by the natural vibration of the load after the ring

Raceway sound source is to be generated after the load caused by the natural vibration of the ring. Since the elastic rings and Roller bearing contact with nonlinear vibration system constituted. When lubrication or machining accuracy is not high flexibility with this feature will be excited about the inherent vibration transmitted into the air then becomes noise. As we all know, even with the highest levels of modern manufacturing technology machining bearing parts, the work surface there will always be varying degrees of tiny geometric errors, so that between the raceway and rolling elements excite vibrations produce tiny fluctuations inherent in the system vibration.
SKF bearings equipment for regular maintenance, operation and external parts replacement bearings were removed for inspection, required in order to determine whether this backing bearings parts can be used again and record usage of good and bad. Should carefully investigate and record split down the bearing and appearance of the situation. In order to understand and investigate remaining amount of lubricant, after the sampling, to a good wash bearings.
Second, check the SKF bearing raceway, rolling surface and the mating surface of the situation and the state of wear of the cage and other signs of damage and anomalies in particular, to observe the raceway running track. Determine the bearing can be used again, to consider the extent of bearing damage, machine performance, the importance of operating conditions, inspection cycles and then later decide.
