ABSTRACT:
A tapered bushing and hub assembly for mounting on shafts sheaves, gears, sprockets, couplings and similar machine elements, in which a tapered, split bushing is inserted in a tapered bore in the machine element and a plurality of lugs secured by screws onto the hub force the bushing inwardly into the tapered bore, seating the bushing into face-to-face contact with the tapered surface of the hub and contracting the bushing firmly onto the shaft. Holes for the screws are provided in the hub and are arranged parallel with the axis of the bore, and preferably extend through the hub. Each lug bears against the side of the hub and the large end of the bushing as the screws are tightened into their respective holes. When the machine element is to be removed from the shaft, a lug may be secured by the screws on the opposite side of the hub to force the bushing outwardly from the tapered bore.
