Roller bearing for e.g. machine tool spindle of driven cutting tool, has paths defining radial planes and pressure lines, where pressure lines cut rotation axis of shaft on side with respect to radial planes

摘要

The roller bearing (1) has an axially effective angular ball bearing (4a) comprising inner and outer rings (40ai, 40aa), where the rings are provided with two sets of paths (41aa, 41ai, 42aa, 42ai). Each path defines radial planes (REa1, REa2) and pressure lines (DLa1, DLa2). The pressure lines cut a rotation axis (A) of a shaft (3) on a side with respect to the radial planes. A pressure angle relating through the inclination of the pressure lines in one of the paths corresponds to the pressure angle resulting in other paths.
