ENCODER WASHER AND BEARING ASSEMBLY COMPRISING SUCH A WASHER

摘要

This encoder washer (20) comprises a magnetic body (24) and is adapted to be mounted on a rotatable ring (6) of a bearing assembly in a position where a surface (26) of this magnetic body defines an air gap (G) with a sensor (42) of the bearing assembly. This surface (26) of the magnetic body (24) is provided with at least one groove (265) defining two edges (266, 268) with said surface, said two edges being located between two lateral edges (262, 264) of said surface (26) or between a radial inner edge and a radial outer edge of said surface (26). The bearing assembly comprises a bearing (2), with an inner ring (6) and an outer ring (4), at least a sensor (42) fast in rotation with a first ring (4), amongst the inner and outer rings (4, 6), and an encoder washer (20) fast in rotation with the second ring (6).
