ROLLING BEARING Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: needle rolling bearing has thin-walled outer race provided with a rolling ways having curved profile of cross-section and rolling bodies made of needles and interposed between them. Cross-section of the race has deflection in the direction of bearing body. The deflection is equal or grater than possible radial heat deformation of bearing parts in operation. Washers made of a rigid antifriction material are fitted with interference at faces of the race. EFFECT: enhanced operation capabilities owing to arrested allowable radial space. 1 tbl
