Abstract
Official abstract text for this publication.
A rolling bearing assembly in which the number of components is reduced, and a high speed operation can be enabled with an increase of the stirring resistance being avoided by a sufficient discharge of lubricant oil and with an increase of temperature within the bearing assembly being suppressed. The rolling bearing assembly includes a pair of raceway rings, which are inner and outer rings, a plurality of rolling elements interposed between the inner and outer rings and a retailer for retaining the rolling elements. Each of the inner and outer rings is provided with an axially extending raceway ring extension portion and an oil supply and drainage mechanism for supplying a lubricant oil, which concurrently serves as a bearing cooling medium, to the bearing assembly and for discharging the lubricant oil to outside of the bearing assembly is provided in the raceway ring extension portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A rolling bearing assembly which comprises: a pair of raceway rings including an inner ring and an outer ring, a plurality of rolling elements interposed between respective raceway surfaces of the inner and outer rings, a retainer to retain the rolling elements; a raceway ring extension portion formed in one or both of the inner ring and the outer ring and extending axially, the raceway ring extension portion having an oil supply and discharge mechanis…
