Abstract: A bushing and hub assembly are clamped together and clamped on a shaft by passing screws through an annular flange provided on the hub and into threaded openings in the bushing. The outside of the bushing is tapered and the inside bore of the hub has a taper which mates with the tapered outside of the bushing.

Abstract: An adjustable flange for a dry lube variable speed sheave assembly having an unmachined bore is centered on a vacuum fixture. A thin dry bearing material is secured and located axially and radially within the flange bore and the annular space between the thin dry bearing material and the flange bore is filled with a high compressive modulus material such as epoxy. The dry bearing material is maintained flat during the process by the application of vacuum through the fixture. After curing, the completed adjustable flange is removed for the fixture and assembled with the sleeve component of a sheave. In accordance with a variation of the method, the separately formed thin dry bearing material is eliminated and a suitable dry lube material is mixed with the epoxy-like cement prior to injecting the same into said annular space. Following curing, this material becomes the dry lube bearing of the flange.
