Abstract

A system for detecting differential bearing damages includes a synthesized tachometer that generates a tachometer signal corresponding to the race speed difference of a bearing assembly such that the bearing damage speed difference dependency can be eliminated and the damage features can be enhanced. The system also includes acceleration enveloping in the cycle domain to further enhance the damage signatures.
