Analysis of Vibration Characteristics of Rolling Bearing Cage Defects
In the fault diagnosis of rolling bearings,the diagnosis of bearing cage defects is the most difficult.On the one hand,the development of cage defects is rapid,especially for stamped steel type cages.On the other hand,the impact characteristics of cages are weak and difficult to effectively capture.In response to this issue,by analyzing on-site cases of rolling bearing cage defects and studying the vibration characteristics of cage defects,an effective method for diagnosing rolling bearing cage defects is provided.That is,in a horizontally arranged shaft system,when the bearing cage defect develops into the later stage,the cage characteristic frequency will modulate the shaft rotation frequency.
