ABSTRACT:
A mounting device for anchoring a machine element coaxially on a rotary shaft. The device fits between the interior cylindrical bore of the machine element and the internal 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 first and second segmented sleeves. The second sleeve has separate internal and external parts so as to afford expansion and contraction of the external part by wedging the internal part of the second sleeve between the external part and the first sleeve, allowing the device to clamp the element on the shaft at any desired position during tightening. The internal surface of the internal part of the second sleeve and the external surface of the first sleeve are similarly tapered so that relative axial displacement of the first and second sleeves effects expansion and contraction of both the interior bore and the external circumference of the combined elements.
