A comparative experimental study on the diagnostic and prognostic capabilities of acoustics emission, vibration and spectrometric oil analysis for spur gears
C. K. Tan,Phil E. Irving,David +2 more
TL;DR: In this paper, an experimental investigation on spur gears in which natural pitting was allowed to occur was conducted, and it was observed that based on the analysis of root mean square (rms) levels only the acoustic emission technique was more sensitive in detecting and monitoring pitting than either the vibration or spectrometric oil analysis (SOA) techniques.
