2105 Damage Diagnosis of Gear Tooth Surface by Synchronous Averaging Processing of Vibration Signal

Abstract

We tried to diagnose the surface failure on the gear tooth using the synchronous averaging method. The vibration signal was emphasized with the synchronous averaging method to reduce a noise. The signal was subdivided into every one pitch of gear to detect the surface failure on the gear tooth. The subdivided waveform of the vibration signal was to evaluate by the maximum amplitude and the standard deviation of the waveform. As a result, it was demonstrated that the synchronous averaging method is effective in the diagnosis of the surface failure on the gear tooth, and can identify the tooth with the surface failure.
