Title:
SOLID-LUBRICATED ROLLING BEARING
Document Type and Number:
WIPO Patent Application WO/2022/118882
Kind Code:
A1
Abstract:
The present invention provides a solid-lubricated rolling bearing configured such that, even when a solid lubricant located between a rolling element and a rolling element has worn, the circumferential positions of the rolling elements do not deviate, so that the inertial force of the rolling elements is unlikely to act on the solid lubricant. In a solid-lubricated rolling bearing including an inner ring (3), an outer ring (2), multiple rolling elements (4), and at least one solid lubricant (7) disposed between a rolling element (4) and a rolling element (4), a retainer (5) for separating the rolling elements (4) in the circumferential direction is provided. The solid-lubricated rolling bearing is configured such that: the retainer (5) has a ring section (5a) and comb teeth sections (5b) that extend in the axial direction from the ring section (5a) and separate the rolling elements; the solid lubricant (7) is located on the inner diameter side or the outer diameter side of the comb teeth sections (5b) of the retainer (5); and projections (8) projecting on the opposite side from the solid lubricant (7) are provided on contact surfaces of the comb teeth sections (5b) of the retainer (5), said contact surfaces contacting the rolling elements (4).
