Arc-shaped segment for assembling a segmented cage, cage and bearing

Abstract

The present disclosure provides a cage for bearings. The cage includes a pocket (2) for accommodating a rolling element of the bearing. The pocket (2) completely encloses the corresponding rolling element on a cylindrical surface where a pitch circle of the cage is located. The pocket has a roughly ellipsoidal shape. The ellipsoidal shape of each pocket (2) has a major axis L1 and a minor axis L2. The major axis L1 and the minor axis L2 satisfy the following relationship: L2<L1≤1.07L2. Through this arrangement, there may be a smaller circumferential clearance or axial clearance between the rolling element and the pocket, so as to improve the vibration of the whole bearing according to different load requirements. The present disclosure also provides a bearing comprising the cage.
