<p>Apparatus for mounting, securing and dismounting a shaft mounted speed reducer to and from a shaft which comprises two interconnected rings at each end of the quill shaft of the speed reducer. One of the rings is a reinforcing ring with approximately half its bore length making a snug fit on the quill shaft and the other approximately half the bore being tapered outwardly to accept a tapered step of a grip ring. The reinforcing ring is split for clamping onto the quill shaft and the grip ring, with a clamping screw fitted across the split. A pattern of radially and axially oriented tapped holes to receive cap screws provide the means for securing the reinforcing ring to the quill shaft and for pulling the grip ring axially toward the reinforcing ring. The grip ring is also split, is stepped and flanged. The step is tapered to match the taper of the reinforcing ring, so that when pulled axially into the reinforcing ring by the cap screws passing through its flange, the grip ring shrinks radially to grip the shaft to be connected to the quill shaft. The grip ring and quill shaft are keyed; the key may be of a special section to reduce key overturn.</p> |
