SOLID FILM LUBRICATION RESEARCH.
Abstract
This report describes progress during the third quarterly period in a program designed to develop a solid film lubricant 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 work toward optimizing the properties of unique self-lubricating composites that are physically and chemically capable of functioning as load-bearing surfaces in an extreme temperature-oxidizing environment. The materials work during this quarter concentrated on the evaluation of metal fillers in the basic tungsten diselenide composite amalgam. The use of silver, copper, iron and tantalum was explored. In the area of functional testing, the results of the first five high speed tests on ball bearings equipped with retainers fabricated from these composites are described. The tests encompass a temperature range of 600 F and a maximum load of 100 lbs. thrust - 100 lbs. radial. (Author)
