RETAINER MADE OF SYNTHETIC RESIN FOR USE IN BALL BEARING AND BALL BEARING |
摘要 |
A retainer of synthetic resin is provided in such a way that abnormal heat generation in a bearing and wear of the retainer due to interference between the retainer and balls are less likely to arise while the bearing is rotating at a high speed. A retainer (5) of synthetic resin includes two annular members (10) made of synthetic resin and facing each other in the axial direction, the annular members defining therebetween a plurality of circumferentially spaced apart pockets (11) in which respective balls (4) are received. Concave spherical surfaces (23) are formed at the circumferential ends of the respective pockets (11) so as to extend along the outer peripheries of the balls (4), and cylindrical surfaces (22) are formed at the axial ends of the respective pockets (11). |
