Using Vibration Amplitude or Fault Location of Rolling Bearing Outer Raceway
Rolling bearings occupies a very important position in mechanical transmission,and their operating conditions direct-ly affect the operating efficiency of the machinery.Therefore,the study of rolling bearing failure has very important theoretical and practical significance.This article proposes a new method of fault location based on fault diagnosis.In this method,three vi-bration sensors are used to collect vibration signals in the running process of rolling bearings,and then correlation analysis and EMD algorithm are used to remove interference,extract the amplitude of vibration signals,and calculate their attenuation.The attenuation of the three vibration signals collected by the three sensors is used to analyze and calculate the exact location of the fault.The method is simple,extracts few feature values,and has high positioning accuracy.And this method can not only accu-rately locate the single point failure of the outer raceway of the rolling bearing,but also can locate multiple failure points at the same time.This is difficult to achieve in previous positioning methods.
