| 摘要 |
This invention relates to taper bush (1,17,23) for securing pulleys, sprockets, coupling flanges or other machine elements onto cylindrical shafts and utilising a plurality of screws or bolts parallel with the hub axis for effecting wedging of the bush (1,17,23) between the hub (B) of the element and the shaft onto which it is mounted. The present invention overcomes the out of balance problem by providing profiling (3,13,19) in the region of the longitudinal slit (3,11,21) so that the disposition of metal is then such as to compensate for the mass imbalance in both the bush (1,17,23) and a co-operating mating hub (B), a rotationally balanced system being thus provided. |
