CROSS-ROLLER BEARING ADMITTING SIGNIFICANT DIFFERENCES.

摘要

Cross roller bearing comprising two concentric rings (1, 2) and a row of crossed rolls (3a, 3b). The rolling surface of the rollers (3a, 3b) has a convex spherical profile with a radius of curvature greater than the diameter of the rollers and less than the radius of the pitch circle and each track of each ring (1, 2) has a concave spherical profile with a corresponding radius of curvature. BR/ Application: in particular to large-diameter orientation rings.
