摘要： PROBLEM TO BE SOLVED: To provide a solid lubrication rolling bearing having no risk of falling or breakage because the conventional spacer is extremely brittle, is easily broken, is damaged by a shock during rotation and produces such a problem that abnormal vibrations occur on a bearing and the spacer falls, or the like, although the spacer type solid lubrication rolling bearing in which the spacer made of solid lubrication material such as graphite is arranged between respective rolling bodies is proposed because grease lubrication cannot be used for the rolling bearing used in an environment of high temperature, high vacuum or the like.SOLUTION: A solid lubrication rolling bearing includes an inner ring 2, an outer ring 1, a rolling body 3, a spacer containing solid lubricant made of selected material and a retainer 5 having pockets which store the spacer and the rolling body while setting at least one spacer and one rolling body 3 as a unit. Thereby, the solid lubrication rolling bearing which has no risk of falling or breakage, hardly causes vibrations and can obtain smooth and safe rotations is provided.
摘要翻译：要解决的问题：为了提供一种固体润滑滚动轴承，由于传统的间隔件非常脆，易于断裂，因旋转过程中的冲击而损坏，并且产生了在轴承上产生异常振动的问题并且间隔件落下等，但是由于润滑脂润滑不能用于在滚动轴承中使用的滚动轴承，所以提出了由诸如石墨的固体润滑材料制成的间隔件布置在各滚动体之间的间隔型固体润滑滚动轴承高温，高真空等环境。固体润滑滚动轴承包括内圈2，外圈1，滚动体3，由选定材料制成的固体润滑剂的间隔件和具有口袋的保持器5 在将至少一个间隔件和一个滚动体3设置为一个单元的同时，存储间隔件和滚动体。由此，具有不会发生坠落或破损的危险的固体润滑滚动轴承几乎不产生振动并且能够获得平稳和安全的旋转。

摘要： A cage for a ball bearing assembly has a pocket for accommodating one of the balls defined at a plurality of locations in a direction circumferentially thereof and each of the pockets has an inner surface so shaped as to represent a concaved spherical surface. A concaved portion extending from an open edge on the cage inner diametric side towards the cage outer diametric side is provided in an inner surface of each of the pockets. The sectional shape of the inner surface of this concaved portion in a cage circumferential direction is represented by an arcuate shape of a radius of curvature smaller than the radius of curvature of the concaved spherical surface defining the inner surface of the respective pocket. The inner surface of each of the pockets may be formed with a film.
