<P>PROBLEM TO BE SOLVED: To provide a cage for an automatic alignment roller bearing capable of reducing insertion load when inserting a rolling body into the cage and preventing improper insertion of the rolling body and damage or deformation of the cage by machining a pocket of the cage without causing a fractured face. <P>SOLUTION: This cage for the automatic alignment roller bearing is provided with a plurality of rolling bodies 6 arranged between an outer peripheral face (raceway surfaces 2a, 2b) of an inner ring 2 and an inner peripheral face 4a of an outer ring 4 so as to roll freely and the cage 8 forming a plurality of pockets 18 for holding each rolling body. The inner peripheral face of the outer ring forms a spherical face on which its radius of curvature agrees with the center X of the bearing, and a guide face Gt forming a predetermined inclination angle is formed by pressing on an inner side holding face G2 on an inward flange part 16 side. In this case, the inclination angle of the guide face Gt forms an angle which agrees with the direction (the optimum insertion angle) D of crossing a line segment Lmin for connecting the shortest distance between a claw piece N of an outward flange part 14 and the inner side holding face G2 on the inward flange part 16 side orthogonally. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
