Abstract
A multi-sided shaft and locking hub apparatus, wherein the locking hub includes an inner hub having a multi-sided inner surface extending around a center hole for receiving the shaft for preventing rotation therebetween, the inner hub including a tapered outer surface, and being cut through, and an outer hub having a tapered inner surface defining a central hole for receiving the inner hub such that the tapered surfaces abut, the outer hub including a multi-sided inner surface defining an extension of the center hole therethrough for receiving the multi-sided shaft with the sides of the inner surface of the outer hub in non-rotating relation, and the tapered surfaces including opposing inner and outer half-holes at spaced locations therearound, for cooperatively receiving threaded members, outer half-holes at some of the spaced locations being threaded so as to be threadedly engageable with the threaded members for pressing the inner and outer hubs together while compressing the inner hub, and the inner half-holes at others of the spaced locations being threadedly engageable with the threaded members for jacking the inner and outer hubs apart.
