Abstract
For mounting a machine element having a bore coaxially on a shaft for rotation with the shaft, there are provided a first member having internal threads, and a split sleeve having external threads adapted to be mounted around the shaft and inside the bore. The threads of the split sleeve have apexes at a uniform diameter when unstressed. The first member is threaded on the external threads of the split sleeve. Also, a second member is spaced from the first member by an amount sufficient to allow the first and second members to embrace opposite sides of the machine element. The threads of the first member and the split sleeve are shaped to cause contraction of the sleeve into fast, gripping engagement with the shaft, as the first and second members frictionally clamp the machine element between these first and second members.
