Gear Defect Diagnosis Using Acoustic Emission

It is widely recognised that Acoustic Emission (AE) is gaining ground as a Non-Destructive Technique (NDT) for health diagnosis on rotating machinery. This paper reports on part of an ongoing experimental investigation on the application of acoustic emission for gear defect diagnosis. In addition, a review of experimental investigations on the applicability of acoustic emissions to gear defect diagnosis is presented. It is concluded that AE offers a complimentary tool for health monitoring of gears.
