ABSTRACT:
An on/off clutch assembly is disclosed having a simplified method for attaching the drive shaft to the hub portion of the drive pulley. The rotating shaft is formed with an integral external threaded portion that is designed to mate with a corresponding internal threaded portion of the hub. The external threaded portion, in conjunction with the internal threaded portion, replace the holes and corresponding cap screws that are used to attach the drive shaft to the hub in current designs. The new design limits the complexity of design and manufacture of the fan drive.
