TL;DR: In this paper, an experimental investigation reported in this paper was centred on the application of the acoustic emission (AE) technique for identifying the presence and size of a defect on a radially loaded bearing.

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.

TL;DR: In this article, an experimental investigation that examines the effectiveness of acoustic emission (AE) for gear defect identification is presented, concluding that application of the AE technique to seeded gear defect detection is fraught with difficulties.

TL;DR: In this article, an ongoing experimental investigation on the application of acoustic emission (AE) for gear defect diagnosis is presented, where the possibility of monitoring gear defects from the bearing casing is examined.

TL;DR: In this paper, an experimental program was conducted to ascertain and validate the applicability of acoustic emission (AE) to seeded gear defect identification, and the relationship between temperature, oil film thickness and AE activity was investigated.
