Abstract:
A free run clutch apparatus is disclosed for damping movement of a device mechanically connected to the apparatus. The apparatus includes a housing which defines an enclosure and a rotor rotatably located within the enclosure, the rotor defining a cavity. A shaft has a first and a second end, the first end of the shaft being rotatably disposed within the cavity. A biasing device is disposed within the cavity between the first end of the shaft and the rotor. Also, a black oxide coating is coated on the biasing device such that when the shaft is rotated in a first direction, a free run of the biasing device within the cavity is permitted. However, when the shaft rotates in a second direction opposite to the first direction, the coated biasing device grabs the rotor so that damping of the rotation of the shaft in the second direction can be achieved.
