Abstract
A mounting device for mounting a machine element to a shaft, particularly in critical timing and high torque applications, is specifically adapted to be frequently assembled and disassembled without coming apart or in any way adversely affecting the operation of the mounting device. The mounting device includes an inner tubular element, an outer segmented tubular element, and a tubular nut. A through extending radial opening is provided in each segment of the outer element, and a circumferential groove in the outer surface of the inner element with first and second axially spaced radially extending walls. A collar (which may be the hub of a sprocket, gear, cam, pulley, roller, or other machine element) surrounds the outer element at the radial openings, and has its own radial openings through which a plurality of fasteners extend into the inner element circumferential groove, and are engageable with the radially extending walls to provide a stop for relative axial movement of the inner and outer elements with respect to each other. A disc connected to the nut allows the nut to be tightened without a wrench.
