Abstract

See full text

A fault detection system is disclosed for predicting bearing failure in a system with a bearing-supported shaft. A position sensor may sense a position of the shaft as the shaft rotates. A controller may receive, from the position sensor, position data indicating a plurality of sensed positions of the shaft. The controller may determine a position or velocity profile for the shaft based upon the received position data and may determine a frequency profile based upon the position or velocity profile. The controller may identify a characteristic of the frequency profile, and identify an expected bearing failure based upon the identified characteristic.
