ABSTRACT:
The bearing and elastohydrodynamic lubrication film test method and apparatus provides measurements related to acoustic resonance frequencies of the ball - raceway - lubricant system of a ball bearing, which frequencies are found to be related to bearing ball, race, and lubricant behavior, the measurements being made while the bearing is actually operating in its normal environment such as for example in a production gyroscopic instrument assembly.
