SOLID FILM LUBRICATION RESEARCH
Abstract
This report describes progress in a program designed to develop a solid film lubricated ball bearing system capable of operation under high speed, high temperature oxidizing conditions. The program's ultimate goal is long-term ball bearing operation at 1500 F - 30,000 rpm, under atmospheric conditions simulating sea-level to 200,000 ft. altitudes. A second program objective is to provide parametric design data relating the operating life, load, bearing size, speed, temperature and environment of these bearing systems. In the materials development area, this report describes further progress in optimizing the properties of unique self-lubricating composites that are both physically and chemically capable of functioning as load-bearing surfaces in an extreme temperature-oxidizing environment. The composites are composed of solid lubricants; such as WSe2, MoSe2, and WS2 that have been combined with gallium or various gallium alloys. In the area of functional testing, the results of initial high speed tests on ball bearings equipped with retainers fabricated from these composites are described.
