Patent ID: 7153031

Claim:
A bearing system comprising: a bearing housing including a bore aligned along a longitudinal axis, the bore having a cylindric inner side wall and a bottom surface within the bore which defines an end of the bore; a bearing received in the bore of the housing which is configured for rotatably supporting a shaft, the bearing having a cylindric outer side adjacent to the inner side wall of the bore and an end face located generally adjacent the bottom surface of the bore; and an anti-slip spring member received in the bore and interposed between the end face of the bearing and the bottom surface of the bore, the anti-slip spring member including a plurality of circumferentially spaced resilient teeth, the plurality of circumferentially spaced resilient teeth engaging at least the end face of the bearing and configured to apply force to the end face of the bearing in a generally axial direction when the spring member is compressed between the bearing and the end of the bore, and further configured to apply force to the end face of the bearing in a direction parallel to the end face in opposition to any rotational movement of the bearing relative to the bore, such that the anti-slip spring member urges the bearing to remain at a fixed rotational position in the bore to prevent movement of the outer side of the bearing relative to the inner side wall of the bore.
