| Zusammenfassung: | The present patent application discloses an overrunning alternator damping pulley. The overrunning alternator damping pulley includes a pulley body, two ball bearings provided on both ends of a shaft hole of the pulley body; and a hub for supporting the two ball bearings. At least one spring holder is provided on the hub. At least one friction spring is installed on the spring holder. One end of the friction spring is inserted to the spring holder. Another end of the friction spring forms a free end spirally extending along an axial direction of the hub. The outer ring of the friction spring is in contact with an inner wall of the pulley body. A damping groove corresponding to the friction spring is provided on the inner wall of the pulley body. |
