Title:
SELF-ALIGNING ROLLER BEARING
Document Type and Number:
WIPO Patent Application WO/2019/240059
Kind Code:
A1
Abstract:
The present invention addresses the problem of improving the assemblability of a bearing in a manner such that, by using a cage-shaped retainer (40) formed of a metal plate, an assembly of an inner ring (10), a plurality of rollers (30), and the retainer (40) can be inserted inside an outer ring (20). A foreign substance is prevented from entering by means of a flange (44) of the retainer (40) and a protruding section (51) of an annular shield plate (50) that is to be attached to the flange (44). Attachment accuracy of the shield plate (50) is improved by bringing a rear surface (52) of the shield plate (50) and the flange (44) into complete contact along the circumferences. A feeler gauge is made insertable between a spherical raceway (21) and the roller (30) by making the protruding section (51) have a smaller diameter than an imaginary spherical surface (S) including the spherical raceway (21).
