Abstract
The coupling of a drive spindle to be fitted to a driven shaft has a fitting bore provided with liner grooves of suitable width opposed to each other diametrically of the bore and extending in parallel axially thereof. Two wedge-shaped superposed liners are fitted in each of the liner grooves in such a combination that the planar surfaces of the inner liners facing each other provide diametrically opposed parallel planar surfaces defining the fitting bore. The inner liners are movable in parallel radially of the fitting bore by axially moving the outer liners to bring the opposed planar surfaces of the inner liners into intimate fitting contact with parallel planar surfaces formed on the peripheral surface of the driven shaft and opposed to each other diametrically of the shaft. The liners in this state are locked to the coupling, rendering the drive apparatus operable free of oscillation.
