ABSTRACT:
For rotationally locking a motor shaft (16) to a head disc (10) one end of the motor shaft (16) is provided with a clamping hub (15). The clamping hub (15) comprises a clamping sleeve (27) in which two clamping elements (28, 29), spaced apart by a spacer tube (30) and extending in the direction of the axis of rotation, are axially movable. Two conical star washers (32, 33) are mounted between the individual clamping bolts (28, 29) and the ends of the spacer tube (30) and provide a centric expansion of the clamping tube (27) at two locations (38, 39).
