BEARING ASSEMBLY WITH INTEGRATED GENERATOR
First Claim
1. A spherical roller bearing comprising:
- an inner ring, an outer ring, first and second roller sets disposed therebetween, and a guide element for guiding the rollers of at least one roller set, the guide element being rotational about a bearing axis of rotation during bearing operation, wherein the bearing further includes a generator for harvesting electrical energy from rotation, and wherein the generator is arranged between the first and second roller sets and provides a magnetic rotor with alternating polarities in circumferential direction and a stator having at least one stator coil, whereinthe magnetic rotor is mounted to the guide element;
the stator is mounted to a common outer raceway of the outer ring, radially opposite from the magnetic rotor, andthe at least one stator coil is formed by a flat conductor provided on a flexible printed circuit board, such that the stator has the form of an annular band.

Abstract
A spherical roller bearing having an inner ring, an outer ring, first and second roller sets disposed therebetween, and a guide element for guiding the rollers of at least one roller set. The guide element is rotational about a bearing axis of rotation during bearing operation. The bearing further includes a generator, arranged between the first and second roller sets, which includes a magnetic rotor with alternating polarities in circumferential direction and a stator having at least one stator coil. The magnetic rotor is mounted to the guide element, while the stator is mounted to a common outer raceway of the outer ring, radially opposite from the magnetic rotor. In accordance with the invention, the stator has the form of an annular band. The at least one stator coil is formed by a flat conductor provided on a flexible printed circuit board.
