Abstract:
Prognosis of gear life using the acoustic emission (AE) technique is relatively
new in condition monitoring of rotating machinery. This paper describes an
experimental investigation on spur gears in which natural pitting was allowed to
occur. Throughout the test period, AE, vibration and spectrometric oil samples
were monitored continuously in order to correlate and compare these techniques
to natural life degradation of the gears. It was observed that based on the
analysis of root mean square (rms) levels only the AE technique was more
sensitive in detecting and monitoring pitting than either the vibration or
spectrometric oil analysis (SOA) techniques. It is concluded that as AE
exhibited a direct relationship with pitting progression, it offers the
opportunity for prognosis.
