Abstract
A method for predicting bearing failure of a differential bearing including an inner race, an outer race, and a plurality of rolling elements positioned between the inner and outer race. The method includes coupling an accelerometer to the differential bearing, generating a bearing performance model, receiving a signal from the accelerometer, and comparing the accelerometer signal to the bearing performance model to predict a differential bearing failure.

A method for predicting bearing failure of a differential bearing including an inner race, an outer race, and a plurality of rolling elements positioned between the inner and outer race, said method comprising:
- coupling at least one accelerometer to the differential bearing;
- generating a bearing performance model;
- receiving a signal from the at least one accelerometer;
- and
- comparing the accelerometer signal to the bearing performance model to predict a differential bearing failure.
A differential bearing assembly for a rotor, said differential bearing assembly comprising:
- an inner race coupled to a first shaft;
- an outer race coupled to a second shaft;
- a plurality of rolling elements positioned between said inner and outer races;
- and
- at least one accelerometer coupled to said outer race, said at least one accelerometer configured to transmit a signal to a bearing monitoring system to facilitate predicting a failure of said differential bearing.
A gas turbine engine assembly comprising:
- a core gas turbine engine comprising
- a first rotor shaft;
- a second rotor shaft;
- a differential bearing coupled between said first and second rotor shafts;
- and
- at least one accelerometer coupled to said differential bearing and configured to transmit a signal to facilitate predicting a failure of said differential bearing.
