More than 90％ of rolling bearing for space use are lubricated by solid lubricant films transferred from retainers to balls and races; successful operation of space driving mechanisms depends on the selection of retainer materials made of self-lubricating composites together with the selection of solid lubricant films deposited in advance on the surfaces of balls and races for the initial stage of operation. The paper describes the process and the results of the selection tests carried out for ball bearing used in the earth sensors which were operated from February 1981 to April 1982 on the Engineering Test Satellite IV. Among 8 candidate materials tested in the form of a retainer, the combination of sputtered MoS2 films and retainers composed of PTFE, glass fibre and molybdenum showed by far the best tribological response. When applied to angular-contact type ball bearings (#7204), this combination lubricated them for more than 10,000 hours at 2,000 rpm under a thrust load of 50N in 10(exp -6) Pa. The bearings actually used in flight were lubricated by PTFE coatings and retainers made from PTFE, glass fibre, and lead oxide for fear that an MoS2 film would be worn off during tests conducted on earth before the launch. Test results indicated this particular conbination is more effective in air than in vacuo. The addition of MoS2 to the composites did not improve their lubricating ability, suggesting that PTFE performs the main role in transfer film lubrication. |
