<p>An improved target wheel (100) is provided for a bearing speed sensor (5). The target wheel includes an annular base (112) which is sized to be press fit on a seat or extension of the inner race of a bearing. The base includes a first end (118) and a second end. A plurality of encoding elements, in the form of spaced apart teeth (116), operatively extend from the first end of the base. The base is bent upwardly near the second end to form a portion (124) which extends radially out of the surface of the base. This portion defines an angle of less than 90° with the place of the base, and preferably forms an angle of about 30° to about 40°. The bent portions at both axial ends provide an increased amount of contact and reduce the amount of 'walking' of the target wheel on the bearing race.</p> |
