AN IN-FLIGHT BEARING TESTER FOR EVALUATING THE PERFORMANCE OF BEARINGS ON ORBITING SATELLITES.

Abstract

An in-flight bearing tester has been developed to evaluate the performance of bearings on orbiting satellites. The bearings are small, R-3-size ball bearings and are tested at a speed of 8000 rpm. The tester supplies data on the running torque and failure times of four test bearings, the temperature of one motor-support bearing, the power consumption of the drive motor, and the pressure (or vacuum) in the immediate area of the test bearings.(Author)
