Abstract: A method for securing a roll-ring onto the end of a roll-axle, comprising prefitting a roll-ring onto a roll-ring mount, and securing the mount with the roll-ring fitted thereon, onto the end of a roll axle. Securement is effected by passing one single screw-threaded bolt axially through an opening through the roll-ring mount, and tightening the bolt into a screw-threaded recess within the end of the roll-axle. The mount has a cylindrical end part (22) on which a roll-ring (30) can be secured, and the mount has an abutment surface (24) against which a roll-ring is to be pressed. Clamping structure (27, 28) presses the roll-ring against the abutment surface, and projections and recesses (25, 29, 31, 34) non-rotatably secure the mount to an end of a roll-axle. The end of the roll-axle has a conical recess in which a conical external surface on the roll-ring mount shape-matingly fits.

Abstract: A roll assembly for a rolling-mill stand has a pair of axis-defining, coaxial, and axially spaced journals, respective roll supports carried in the journals and rotatable therein about the axis, and a roll ring engaged between the supports. The roll supports are each formed with a pair of radially spaced and separate annular surfaces both centered on the axis and the surfaces of one support are directed at least generally axially toward the other roll support. At least one of the surfaces of each pair is substantially frustoconical and forms with the axis a different angle from the other of the surfaces of the pair. One of the supports is formed at the axis with an axially extending passage and the roll ring is formed with generally axially oppositely directed pairs of annular surfaces respectively complementary to and flatly engaging the annular surfaces of the roll supports. An extension stem axially fixed to the other of the supports extends with radial play through the passage and is provided with a nut or the like bearing on the one element, normally the service-side element, for pulling the two support elements axially toward each other and thereby axially compressing the roll ring between the annular surfaces of the roll supports.

Abstract: A roll device includes a roll shaft and at least one roll ring mounted on the roll shaft. A lock means is securable to the roll shaft. A centering element is disposed between the roll ring and the roll shaft to center the roll ring. A first resilient element is axially interposed between the lock means and the centering element. A second resilient element is axially interposed between the lock means and the roll ring. The lock means applies axial force to the first and second resilient elements to position the centering element relative to the roll ring and roll shaft, and clamp the roll ring to the roll shaft for common rotation therewith. The spring rates of the first resilient element can be made less than that of the second resilient element to regulate the relative amount of axial forces applied to these elements.

Abstract: A forming roll of hard material, such as cemented tungsten carbide, is mounted on a driving shaft. The shaft has a shoulder either integral with the shaft or in the form of a nut threaded thereon abutting one axial end of the roll while the other end of the roll is in the form of a wide angle ''''V.'''' A keying element is mounted on the shaft having a wide angle ''''V'''' configuration complementary to that of the roll, and this last mentioned element is keyed to the shaft for transmitting torque from the shaft to the roll.
