RETAINER AND ROLLING BEARING |
摘要 |
A cage 11 for holding a plurality of rolling elements 20 incorporated between an inner ring and an outer ring by a plurality of pockets with their centers arranged at regular intervals in the revolving direction of the rolling elements 20 includes at least one drive pocket 14 having a smaller clearance 22 in the revolving direction of the cage 11 and rolling elements 20 than the clearances of the remaining non-drive pockets 15 in the cage 11. Thus, drive power to be applied to the cage 11 can be always maintained constant and the swinging motion of the cage 1 during revolution can be prevented, thereby being able to reduce cage sounds. |
