US 6,068,408 A · Cage for a rolling bearing

Abstract

In a rolling bearing including an inner race; an outer race; a plurality of rolling elements rollingly arranged between the inner race and the outer race; and a cage holding the rolling elements, the cage has an annular shape and a plurality of pockets which are formed at plural positions in a circumferential direction of the cage, in which each of the pockets has an opening peripheral portion which is curved to a direction of increasing a distance from a center of the rolling elements. The opening peripheral portion forms a chamfered face or a convex face. The rolling bearing can sufficiently ensure the lubrication of sliding contact portions between the cage and rolling elements so that vibrations and noises of the rolling bearing are lowered.
