Bearing assemblies incorporating roller bearings

摘要

A bearing assembly has several spherical roller bearings (10) with a single row of compact rollers (13) with longitudinal axial dimensions (9) substantially the same as their maximum diametric dimensions (d) normal to the axis. The rollers (13) have convex or concave contact surfaces (15) engaging with complementary contact surfaces (16) of inner and outer rings (11, 12). These rings (11, 12) have the same width, i.e. axial dimension, not much larger than the axial dimension (a) of the rollers (13). The rollers (13) are all inclined so that a projection of a central plane (P) perpendicular to the longitudinal axis extends at a set angle to a common central plane (R) extending radially of the rings.
