Failure Mode Analysis of Lubricated Satellite Components.
Abstract
A failure mode analysis performed for lubrication malfunctions or failures in ten different spacecraft identified 12 possible failure modes. These were lubricant degradation, lubricant dewetting, slip ring and brush wear, improper lubricant transfer, inadequate lubricant quantity, lubricant volatility effects, lubricant incompatibility, torque variations, cage and bearing instability, cage wear, lubricant creep, and film thickness. This report includes a discussion of a four phase effort required to develop accelerated tests for predicting lubricant life performance in space systems. A program is recommended for the development of accelerated tests to be used in selecting improved long life lubricants for space systems. (Author)
