Development of a Life Test Platform for Bearings Lubricated by Solid Lubricant under the Vacuum and Temperature Cycling Environment

Abstract:

In order to investigate the life of bearings lubricated by solid lubricant (BLSL), which are installed in the rotational parts of spacecraft, a test platform has been developed. The platform can test the life of BLSL working under the vacuum environment with high-low temperature cycle conditions. The test platform consists of three systems of loading, measurement, and power and speed control. A corresponding computer program was also developed to measure, monitor and record test data. The working life of deep groove ball bearings lubricated by MoS₂ solid lubricant was tested in 5×10^-4Pa vacuum. The surface observation and analysis for the damage condition of the failed bearings were also conducted.
