  • Over-running clutch pulley with increased surface microhardness
    Patent number: 7191880
    Abstract: The over-running clutch pulley (10) of a preferred embodiment of the invention includes a sheave member (20), a hub member (22) located substantially concentrically within the sheave member, and a clutch member (24), which cooperate to rotationally engage an input device (12) and an output device (14). The sheave member preferably includes a sheave input section (26) adapted to engage the input device, and a sheave clutch section (28) defining a sheave clutch surface (30). Similarly, the hub member preferably includes a hub output section (32) adapted to engage the output device, and a hub clutch section (34) defining a hub clutch surface (36). 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.
