 note = {This paper describes three topics for the study on oil-lubricated ball bearings and lubricants in space. Firstly, a numerical study on EHL point contacts with nonuniform inlet film thickness, which results from repeated ball passings, is presented. At high values of speed and viscosity, the central film thickness can decrease with speed and viscosity, which agrees with common experimental experience. Secondly, downsized, high-resolution Laser Induced Fluorescence system for measuring oil film thickness of a ball bearing was developed in TIT/JAXA collaboration. The measurement with the LIF system revealed that the film thickness on the outer-raceway was decreased by repeated ball passings, and, finally, very thin film of approximately 0.41 micrometer was left to contribute to bearing lubrication. Lastly, some tribological properties of an ionic liquid were investigated by using a pin-on-disc friction and wear tester. Due to running-in, the coefficient of friction of the ionic liquid decreased with time to a very low value. Wear of the specimens lubricated with the ionic liquid was substantially comparable to that with a paraffin-based oil., 資料番号: AA0049054035, レポート番号: JAXA-SP-05-008},
