Mounting Device Abstract A mounting device for anchoring a machine element coaxially on a rotary shaft. The device fits between the machine element and 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 similarly tapered inner and outer segmented sleeves, so that relative axial displacement of the sleeves effects radial expan- sion and contraction of the combined elements. At one end the inner sleeve cooperates with a nut to effect the axial displacement of the sleeves. The outer sleeve has separate segments coupled with said nut to permit limited pivotal move- ment of the segments. In another embodiment, the sleeves are constructed to avoid relative rotation between the sleeves by a locking portion. In a third embodiment, the inner sleeve also has separable segments and a tubular element which are interconnected similarly to the interlocking of the outer sleeve segments with the nut. Improved performance is provided by providing anti friction bearing elements between the nut and the outer sleeve and anti-friction screw threads between the nut and the inner sleeve. Alternatively, an anti-friction coating may be applied to the nut.
