Abstract:
1. A universal joint shaft, comprising: a connecting shaft; a first universal joint that is attached to a first end of the connecting shaft; a second universal joint that is attached to a second end of the connecting shaft; and a coupling sleeve that defines a longitudinal axis and that is connected to the first universal joint, the coupling sleeve including a receiving bore with an opening for receiving a journal of a roll, wherein the receiving bore forms transmitting faces for transmitting torque, and wherein the coupling sleeve includes a ring having a cylindrical bore that is provided in the region of the opening for supporting the journal against the cylindrical bore by means of a correspondingly shaped cylindrical outer face, the cylindrical bore beginning at the opening of the receiving bore and extending completely throughout the entire axial length of the ring, and wherein the coupling sleeve includes a first conical face that is arranged concentrically relative to the longitudinal axis and remote from the opening and which is provided for contacting a correspondingly designed first counter face at the journal of the roll in order to avoid radial play, as well as means which force-load the first conical face along the longitudinal axis towards the roll.
