Abstract
The over-running clutch pulley () of a preferred embodiment of the invention includes a sheave member (), a hub member () located substantially concentrically within the sheave member, and a clutch member (), which cooperate to rotationally engage an input device () and an output device (). The sheave member preferably includes a sheave input section () adapted to engage the input device, and a sheave clutch section () defining a sheave clutch surface (). Similarly, the hub member preferably includes a hub output section () adapted to engage the output device, and a hub clutch section () defining a hub clutch surface (). In the preferred embodiment, either the sheave clutch surface, the hub clutch surface, or both, have a surface microhardness greater than the hub output section.
