Applications of Vibration Analysis to the Condition Monitoring of Rolling Element Bearings

Abstract

Condition monitoring methods for rolling element bearings, which utilize the high frequency vibrations generated by bearing damage, have been investigated and compared experimentally. Kurtosis values, spectra of vibration signal envelopes and pulse measurement methods provided effective detection of early damage, but kurtosis in particular was not effective in evaluating extensive damage, where a combination of methods is required. Comparison of different accelerometer types used as vibration sensors gave very similar results, but an acoustic emission transducer provided indications of incipient damage significantly earlier than the accelerometers. Test were conducted under reasonably favourable conditions of measurement so further testing under less favourable conditions is proposed, and the effect of such conditions is briefly considered.
