Detection of Seeded Faults in an Epicyclic Gearbox by Signal Averaging of the Vibration.

摘要

This paper reports on a new technique for obtaining signal averages of the individual planetary gears and the sun gear using a single transducer. Individual epicyclic components can now be analysed using standard signal average enhancement techniques to diagnose gear condition. Analyses of data from epicyclic gearboxes with seeded faults are presented.
