A roll, particularly a back-up roll, for rolling flat material is composed of a rotating roll shell and a unit arranged within the roll shell for influencing the bending stiffness of the roll shell. The unit for influencing the bending stiffness of the roll shell is a friction bearing in the form of a body of rotation. The body of rotation can be adjusted by rotating the body. The body of rotation is shaped in such a way that the load application surface thereof corresponding to the zone of the roll shell to which load is applied is part of the circumferential surface of a rotation-symmetrical body and the edge of this circumferential surface is shaped in such a way that along the circumference of the body of rotation the width and/or position of the load application surface vary.

Roll for influencing flatness

A rolling mill drive with gear-type joint spindles arranged between driveable rolls and the gear units of the driveable rolls and equipped with a device for circulatory or pressure lubrication of the gear units. Each spindle has a grooved oil supply ring connectable to an oil supply, wherein oil can be supplied through a central duct of the spindle shaft to the gear-type joints, and with a stationary housing surrounding the spindle shaft at a distance and serving for the oil discharge, and with an oil delivery pump connectable on the pressure side to the oil supply rings and interacting with an oil cooler. Each gear-type joint spindle is surrounded by a pipe at a radial distance so as to form an annular oil return duct. The pipe is open at the end facing the gear unit and protrudes into the oil collection housing provided at this location for effecting oil discharge. The oil return duct is in circulatory oil connection with the central duct through the internally toothed spindle sleeve on the side of the roll stand. On the side of the roll stand, the pipe is guided in an articulated manner and sealed toward the outside and relative to the spindle sleeve through a spherical joint arranged on the pipe.

Rolling mill drive with gear-type joint spindles and with a device for

A device for axial displacement for a roll in a rolling stand. The roll is mounted in a chock which is guided in a roll housing. The chock is adjustably guided in the rolling stand. The roll is axially displaced by a hydraulic piston-cylinder assemblies acting on the rolling stand and connected to the support member of the roll bearing. The roll bearing is axially slidingly guided in the chock. The chock has a guide for a sliding carriage which is provided with a coupling device for the roll neck. The hydraulic piston-cylinder assemblies are articulated to this sliding carriage.
