Title:
CAGE FOR ROLLING BEARING, ROLLING BEARING, AND METHOD OF DESIGNING CAGE FOR ROLLING BEARING
Document Type and Number:
WIPO Patent Application WO/2023/176181
Kind Code:
A1
Abstract:
In the present invention, circumferentially opposing holding portions in pockets form a Gothic arch shape by extending arcs so as to intersect each other, and, of wedge angles 2θn of a plurality of wedge each defined by a tangent line T at a distal end portion of the holding portion in a predetermined pocket and a tangent line T at the distal end portion of the holding portion in each pocket spaced apart from the predetermined pocket in the circumferential direction, the minimum positive value 2θmin satisfies θmin > tan-(1)(μ), where μ is the coefficient of friction between a rolling element and a cage.
