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.

First Claim:
Show all 9 claims
I claim:     1. A tapered bushing and hub assembly for mounting sheaves, gears, sprockets, couplings and similar machine elements on shafts, comprising a hub with a shaft bore having an annular tapered inner surface, a split bushing disposed in said hub and having an annular tapered outer surface for face-to-face contact with the tapered surface on said hub, a plurality of threaded holes spaced outwardly from said bushing and extending parallel with the axis of said bore, separate lugs for said holes having opposite ends, one end of which seating on the large end of said bushing and the other end of which seating on said hub, each of said lugs having a hole between the ends thereof, and screws extending through said holes in said lugs and threadedly received in said holes for pressing said lugs against said hub and bushing and thereby urging said bushing into said bore for contracting said bushing onto the shaft, the holes in said lugs being sufficiently larger than the respective screw to permit tilting of the lug relative to the screw as the screw presses the bushing into the hub.
