Abstract
An over-running clutch pulley of the preferred embodiment includes a sheave member, a hub member located substantially concentrically within the sheave member, a sealing member, and a clutch member, which cooperate to rotationally engage the drive belt and the cylindrical shaft. The sheave member preferably includes a sheave input section adapted to engage the input device, a sheave clutch section defining a sheave clutch surface, and a sheave flange element. Similarly, the hub member preferably includes a hub output section adapted to engage the output device, a hub clutch section defining a hub clutch surface, and a hub lip element. The sealing member preferably includes a seal outer section frictionally engaged with the sheave flange element, and a seal inner section slidably engaged with the hub lip element. The sealing member preferably functions to substantially seal a cavity defined by the sheave flange element and the hub lip element.
