A mounting device (10) for coaxially anchoring a machine element (11) upon a rotary shaft (12). Device (10) fits between the interior bore of machine element (11) and the cylindrical surface of shaft (12) and is effective to position element (11) at any desired position longitudinally of shaft (12) and at any angular position circumferentially of shaft (12). Device (10) has inner and outer sleeves (20, 50), the mating surfaces of which are similarly tapered so that relative axial dispacement of the sleeves (20, 50) effects expansion and contraction of the interior bore and external surface of the combined elements. Rotation of a threaded nut (40) at one end of device (10) effects the relative axial displacement of inner and outer sleeves (20, 50) to afford expansion and contraction of outer sleeve (50) without straining the material of sleeve (50) or nut (40). |
