Incipient Failure Detection: Incipient Failure Detection in Ball Bearings

Abstract

This document reports the results of an investigation of incipient failure detection in ball bearings by means of acoustic monitoring techniques. The change of acoustic emanation strength with bearing condition was studied to determine if changes within the frequency spectrum monitored would manifest the onset of a bearing failure. This investigation showed that the acoustic energy emitted from bearings is very sensitive to bearing condition and provides a clear indication of the onset of bearing failure.
