Research on Pitting Corrosion Fault Model of Vibrating Screens Rolling Element Bearing

Abstract:

In order to solve the problem of pitting corrosion discrimination of rolling element bearing on vibrating screen. We established the vibrating model of pitting corrosion of rolling element bearing inner and outer rings faults on vibrating screen based on rotating machinery rolling element bearings operating mechanism and Hertz contact theory. We simulate this model and analyze the results. The results show that, when the outer ring of the rolling element bearing of vibrating screen has multi-point pitting corrosion, there is an apparent modulation phenomenon at the response amplitude. When the inner ring of the rolling element bearing of vibrating screen has multi-point pitting corrosion, there is a slight modulation phenomenon at the response amplitude.
