Abstract : This report presents the results of a balanced study of bearings and gears for heavily loaded, low velocity space simulator applications, integrated with a research effort directed toward the development of materials, lubricants, application processes, and evaluation and testing techniques. Solid film lubricants consisting of molybdenum disulfide and graphite with silicate and epoxy type binders, and thin film platings of gold and silver, were among the better performers. Molybdenum disulfide-glass, and graphite-aluminum phosphate were among the more successful solid film lubricants developed. Apiezon L, a low vapor pressure petroleum distillate used for comparison purposes exhibited good performance characteristics. Lubricated cylindrical, spherical, ball, and tapered rolling element bearings of 30 mm, 50 mm, and 100 mm bore sizes were tested in this effort. The gears tested were helical.
