摘要

The arrangement (1) is assembled of four bearing rings (2, 6, 8, 11), each providing a path for the ball elements (4, 7, 9, 12) and rotating around a central axis (3). The third and the fourth bearing ring (8, 11) are arranged in order to form an acute angle with the central axis (3). The second and the third ring (6, 8) are made of a single piece in a wedge shape (13) and provided with outer teeth (14) engaging with complementary teeth located at a pinion.
