SOLID FILM LUBRICATED BEARING RESEARCH PROGRAM.

Abstract

The program discussed in this report was divided into two phases. The first phase consisted of analytical evaluations of potential bearing designs, solid lubricant materials and lubricant supply systems as applied to accessory-sized ball bearings. The second phase was devoted to laboratory determinations of lubricant materials tensile strength and thermal properties followed by evaluations of selected solid lubricant materials and bearings. These tests included friction and wear evaluations of both lubricant and bearing materials in a friction and wear rig; evaluations of full-scale bearings in atmospheric and vacuum environments at temperatures ranging from -249F to 1500F, at speeds up to 24,000 rpm for periods up to three hours; and vacuum-environment testing of bearings which had been exposed to a fast neutron dose of approximately 10 to the 17th power neutrons/sq cm (>1.0 MEV). Test results of this program indicated that no lubricant tested, regardless of the supply system used or conditions under which tested, showed any clear superiority when compared to other dry film lubricants.
