The Fault Diagnosis Of The Roller Bearing Based On The Wavelet And SVM

Roller bearings are one of common components in machineries and vulnerable to damage. Many faults of mechanism are related to roller bearings. The running state of roller bearings directly influences the performance of the whole equipment. Thus, developing fault diagnosis of roller bearings has great practical significance.In this paper, at first the fault mechanism and the vibration characteristics of Roller bearings are summarized. Roller bearings experiments are carried on the faults diagnose bench in the laboratory to make a research on Roller bearings fault diagnosing. We collect the vibratory singles in the four modes of normal bearings, damaged inner ball track bearings, damaged outer ball track bearings, bearing balls pitting .With the vibratory singles we use wavelet packet analysis method to...
