ABSTRACT:
A bushing and hub assembly for mounting sheaves, sprockets, gears, couplings and similar machine elements on a shaft, wherein two types of tapered bushings are used, the bushings having bodies of the same taper used with a single hub which is compatible with both bushings. One of the bushings has a radially extending annular flange at the large end of the tapered body and the other bushing is flangeless. The screw holes and plain holes are provided in the flange and at the interface of the bushing and hub for securing the selected bushing in place in the hub for mounting the machine element on the shaft with screws for tightening the bushings securely in place on the shaft and in the hub bore. The two bushings and the sidewalls of the hub all have the same taper and are interchangeable with one another, to provide optimum performance and convenience of installation.
