Abstract:
1. An over-running clutch pulley for rotationally engaging an input device and an output device, comprising: a sheave member including a sheave input section adapted to the engage the input device, and a sheave clutch section defining a shave clutch surface; a hub member located substantially concentrically within said sheave member and including a hub output section adapted to engage the output device, and a hub clutch section defining a hub clutch surface substantially adjacent said sheave clutch surface, said sheave clutch surface and said hub surface being inwardly directed and cylindrically shaped; a wrap spring clutch member adapted to engage said sheave clutch surface and said hub clutch surface upon the acceleration of said sheave member in a first rotational direction relative to said hub member, and to disengage said sheave clutch surface and said hub clutch surface upon the deceleration of said sheave member in the first rotational direction relative to said hub member; said sheave clutch surface, said hub clutch surface and said hub output cooperating to define a clutch free volume located radially inward of said wrap spring clutch member; a clutch lubricant located near said wrap spring clutch member and including a base material selected from the group comprising ether, ester, and mineral oil; a bearing member located between said sheave member and said hub member, and adopted to allow relative rotations movement or said sheave member and said hub member; and a bearing lubricant located near said bearing member and including a base material selected from the group comprising ether, ester, and mineral oil.
