ABSTRACT:
A polygonal connection for joining a hub with a shaft includes a bore in the hub and a joining portion on the shaft. In one embodiment both the bore and joining portion have mating, non-circular polygonal cross sections. In that embodiment, radially expandable fasteners are located in the vicinities of corners of the polygonal cross section of the joining portion of the shaft. In another embodiment, the bore in the hub and the joining portion of the shaft have circular cross sections, and at least one radially expandable fastener is located on the circumference of the joining portion of the shaft. In both embodiments, each fastener runs parallel to the axis of the shaft, and the longitudinal axis of each fastener is disposed within the perimeter or circumference of the joining portion of the shaft.
