SOLID LUBRICANT FILM STRUCTURE AND SOLID LUBRICANT ROLLING BEARING

摘要

PROBLEM TO BE SOLVED: To form a molybdenum sulfide film having superior wear resistance at the time of forming the molybdenum sulfide film by sputtering and to improve the wear resistance of the molybdenum sulfide film of a solid lubricant rolling bearing. ;SOLUTION: In this solid lubricant rolling bearing, a lubricating crystal film of molybdenum sulfide is formed by means of sputtering on respective friction surfaces of one or more kinds selected from the group consisting of steel inner and outer races and rolling elements, as parts constituting the rolling bearing. At this time, a lubricating crystal film, where the secondary structure of the molybdenum sulfide crystal has a structure in which a large number of short-hair-like crystals 13 are grown on the surface of a dendrite body 12 consisting of continuously connecting short-fiber-like crystals 11 haying arms 11a, is formed.;COPYRIGHT: (C)1999,JPO
