Abstract:
It is widely recognised that acoustic emission (AE) is gaining ground as a non-
destructive technique (NDT) for health diagnosis on rotating machinery. The
source of AE is attributed to the release of stored elastic energy that
manifests itself in the form of elastic waves that propagate in all directions
on the surface of a material. These detectable AE waves can provide useful
information about the health condition of a machine. This paper reports on part
of an ongoing experimental investigation on the application of AE for gear
defect diagnosis. Furthermore, the possibility of monitoring gear defects from
the bearing casing is examined. It is concluded that AE offers a complimentary
tool for health monitoring of gears.
