摘要:
To provide a cage for a rolling bearing in which the rolling bearing is lubricated, for example, by a combination of oil bath lubrication and a forced-feed oiling pump, and even when the forced-feed oiling pump is stopped, a defective lubrication can be prevented, and also to provide a bearing for wind power generation which is provided with this cage.Lubricating oil sumps 24 are provided at a larger-diameter ring 21 of a cage 14. Each lubricating oil sump 24 is provided between a tapered roller 13 and a tapered roller 13 so as not to abut with the tapered roller 13. With this arrangement, when the lubricating oil sump 24 is located in lubricating oil stored at a lower portion of the bearing, the lubricating oil is held in the lubricating oil sump, and in accordance with subsequent rotation, the lubricating oil held in the lubricating oil sump 24 is allowed to drop.

Deep groove ball bearings are used as bearings supporting both side portions of a worm. In the first bearing on the side of a motor, the curvature radius of a raceway groove in an inner ring or the curvature radius of a raceway groove in an outer ring are set to a specific numerical range with respect to the diameter of a ball.
