Abstract
The over-running clutch pulley () includes a sheave member (), a hub member () a clutch member (), and a coating (), which cooperate to rotationally engage an input device () and an output device (). The sheave member () preferably includes a sheave input section () defining a sheave input surface () 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 () defining a hub output surface () adapted to engage the output device (), and a hub clutch section () defining a hub clutch surface (). The coating () is disposed on the sheave input surface (), the sheave clutch surface (), the hub output surface (), and the hub clutch surface (), which protects against substantial corrosion and increases the wear resistance of these surfaces, while minimizing the cost of the over-running clutch pulley ().
