<p>An over-running clutch pulley (10) of the preferred embodiment includes a sheave member (20), a hub member (22) located substantially concentrically within the sheave member, a bearing member (24), a sealing member (26), and a clutch member (28), which cooperate to rotationally engage the drive belt (16) and the cylindrical shaft (18). The sheave member preferably includes a sheave input section (30) adapted to the engage the input device (12), and a sheave clutch section (32) defining a sheave clutch surface (34). Similarly, the hub member preferably includes a hub output section (36) adapted to engage the output device (14), and a hub clutch section (38) defining a hub clutch surface (40). The bearing member preferably positions the sheave member and the hub member such that the sheave member and the hub member define a radial gap (42). The sealing member (26), which is preferably located in the radial gap, preferably sustantially prevents substantial passage or any fluid through the radial gap.</p> |
