Abstract

A system and method for monitoring the condition of a gear assembly analyzes a signal output by a vibration detector that is attached to the gear assembly. Each time that an amplitude of the signal output from the vibration detector exceeds a threshold value, the system assumes that a debris particle has passed between meshing parts of the gear assembly. The number of times that this occurs, and possibly the amplitude of the vibrations are analyzed to determine a condition of the gear assembly, and possibly a damage index. This system and method are particularly applicable to planetary gear arrangements where the vibration detector can be mounted on a fixed ring gear of the gear assembly, or a structure upon which the fixed ring gear is mounted.
