Abstract
The over-running clutch pulley of a preferred embodiment of the invention includes a sheave member (20), a hub member (22) located substantially concentrically within the sheave member, a clutch member (24), a clutch lubricant (26) located near the clutch member, a bearing member (28) located between the sheave member and the hub member, and a bearing lubricant (30) located near the bearing member, which cooperate to rotationally engage an input device (12) and an output device (14). The sheave member preferably includes a sheave input section (32) adapted to engage the input device, and a sheave clutch section (34) defining a sheave clutch surface (36). Similarly, the hub member preferably includes a hub output section (38) adapted to engage the output device, and a hub clutch section (40) defining a hub clutch surface (42). The clutch lubricant (26) and the bearing lubricant (30) preferably include a base material selected from the group comprising ether, esther, and mineral oil.
