Abstract
The present specification discloses a tapered, longitudinally-split contractible taper bush for securing pulleys, sprockets, coupling flanges or other machine elements onto cylindrical shafts and utilizing a plurality of screws or bolts parallel with the hub axis for effecting wedging of the bush between the hub of the element and the shaft onto which it is mounted. Known bushes of this type suffer an out of balance moment due to the arrangemnt of locking holes, part threaded holes provided for de-wedging and bush removal, and the size of the longitudinally extending slit which is necessary to promote flexibility in the bush for bush removal. The present invention overcomes the out of balance problem by providing profiling in the region of the longitudinal slit so that the disposition of metal is then such as to compensate for the mass imbalance in both the bush and a co-operating mating hub, a rotationally balanced system being thus provided.
