Bearing i.e. single-row rotary ball bearing, for use in bearing arrangement, has claw rings and magnetic poles secured on two parts of planetary gears, respectively, where planetary gears exhibit specific transmission ratio

摘要

The bearing (2) has a claw pole generator (6) comprising two claw rings (7, 9) that comprise an induction coil (10), where a rotational axis is surrounded by the coil. Claws (8) of the claw rings form magnetic circuits that are provided with magnetic poles (13). The rings and the poles are secured on a sun wheel (15) and a ring gear (17) of planetary gears (14), respectively, where the gears exhibit a transmission ratio of greater than 1. A planetary carrier (21) is secured at an outer surface (22) of a bearing ring (3) i.e. rotary bearing ring, that points to another bearing ring (4).
