ABSTRACT:
A method and device for mounting and centering a thin wall hub of a driven member onto a drive shaft provides the shaft with a radial end face which projects an axially extending reduced diameter threaded stud which fits within a central aperture of the hub and secures a nut to clamp the hub between the end face and nut. A raised shaft embracing portion centered on the hub axis snugly embraces the outer periphery of the drive shaft and axially aligns the two members. The drive shaft may also incorporate a drive pin which extends axially from the end face and is seated in a second aperture in the hub to provide effective driving of the hub by the drive shaft.
