A mounting device (10, 10') for coaxially anchoring a machine element (11, 11') upon a rotary shaft (12, 12'). The device fits between the interior bore (13, 13') of the machine element and the cylindric al 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 (20, 20') and outer (50, 50') 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 (13, 13') and external surfac e of the combined elements. Rotation of a threaded nut (23, 45') at one end of the device effects the relative axial displacement of the inne r and outer sleeves to afford expansion and contraction of the outer sleeve (50, 50'). |
