ABSTRACT:
A flanged bushing mounting adaptor for use in mounting a flanged bushing in the hub of a shaft-mountable structure, the hub having a tapered bore with recesses formed therein, and the bushing having a tapered barrel and a flange with threaded and unthreaded holes therein. The adaptor has a tapered outer circumferential surface for wedging engagement with the oppositely tapered hub, and a tapered bore for wedging engagement with the oppositely tapered barrel of the bushing. The adaptor also includes a plurality of threaded bores corresponding to the unthreaded holes in the flange, for receiving screws or bolts to secure the bushing to the adaptor and to draw the assembly into the hub. Bosses, or recesses with set screws, corresponding to the recesses in the hub, may be included on or in the outer surface of the adaptor to prevent relative rotation between the adaptor and the hub.
