Abstract
A mounting device for anchoring a machine element having a tapered bore coaxially upon a rotary shaft. The device fits between the interior tapered bore of the machine element and the cylindrical surface of the shaft and is effective to position the element at any desired position longitudinally of the shaft and at any angular position circumferentially of the shaft. The device has inner and outer segmented sleeves, the mating surfaces of which are similarly tapered so that relative axial displacement of the sleeves effects expansion and contraction of the interior bore and external surface of the combined elements. Rotation of an internally threaded nut at one end of the device effects the relative axial displacement of the inner and outer sleeves to afford expansion and contraction of the outer sleeve without straining the material of the sleeve or the nut. The external surface of the outer sleeve is tapered for mating with the tapered bore of the machine element and has an abutment flange to maintain the machine element at a fixed, axial position during and after mounting of the machine element upon the shaft.
