摘要： PROBLEM TO BE SOLVED: To extend the bearing service life by excellently maintaining the lubricating state inside a solid lubrication rolling bearing over a long period of time.SOLUTION: In the solid lubrication rolling bearing, a retainer 4 is configured to retain balls (rolling elements) in pockets 4a between inner/outer rings 1, 2. One of the pockets of the retainer stores a solid lubricant only or one set of two lubricating members 5, respectively formed of a solid lubricant and a binder and formed into a hemispherical shape, in such a posture that mutual planes of the lubricating members face each other. A leaf spring 6 is inserted between the planes of the respective lubricating members 5 so as to press the spherical surfaces of the respective lubricating members 5 each against an inner-ring raceway surface 1a and an outer-ring raceway surface 2a and to bring the spherical surfaces of the respective lubricating members into sliding contact with the raceway surfaces in a state that the respective lubricating members are engaged with the retainer 4. Accordingly, a hard-to-peel adhered film of the solid lubricant is evenly formed on each of raceway surfaces 1a, 2a. As a result, it is possible to excellently maintain the lubricating state between the inner-ring raceway surface 1a/the outer-ring raceway surface 2a and the balls over a long period of time, thereby achieving the extension of the bearing service life.
摘要翻译：要解决的问题：通过在固体润滑滚动轴承内长时间保持润滑状态来延长轴承的使用寿命。解决方案：在固体润滑滚动轴承中，保持器4构造成将球（滚动元件）保持在内/外环1,2之间的凹穴4a中。保持器的一个凹口仅存储固体润滑剂或一个一组两个分别由固体润滑剂和粘合剂形成的润滑构件5，其形状为半球形状，使得润滑构件的相互平面彼此面对。在各个润滑部件5的平面之间插入板簧6，将各润滑部件5的球面分别压靠在内圈滚道面1a和外圈滚道面2a上，各个润滑部件的表面在各个润滑部件与保持器4接合的状态下与滚道面滑动接触。因此，固体润滑剂的难以剥离的粘合膜均匀地形成在每个滚道表面上 1a，2a。结果，能够在内圈轨道面1a /外圈滚道面2a与滚珠之间长时间地良好地保持润滑状态，从而实现轴承使用寿命的延长。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a rolling bearing device in which an absolute amount of a lubricant contributing to lubrication during rotation of the bearing can be easily increased without increasing the number of component items of the bearing.SOLUTION: The rolling bearing device includes inner rings 2, outer rings 3, rolling bodies 4, retainers 5 and an inner ring spacer 6. The inner ring spacer 6 is formed of an oil-retaining member 7 that comprises a sintered metal impregnated with lubricating oil, and of a spacer cover 8 fitted to the outer perimeter of the oil-retaining member 7. Through centrifugal force generating in the oil-retaining member 7 when the bearing rotates, lubricating oil is scattered to the outer diameter side from a chamfer 7d of the oil-retaining member 7 via an oil supply route S to thereby lubricate the interior of the bearing with the oil.
