A clamping joint between a universal joint spindle and a stub or wobbler of a rolling mill roll is formed by providing wedge members between the juxtaposed surfaces of the coupling box and roll stub and by bracing the wedge members by springs in the coupling head bracing the wedge members against a shoulder of the roll stub.

Clamping joint between a spindle head and a roll stub

A connection between the spindle head of a gear-type or universal joint spindle and the neck of a roll includes wear plates are placed between locating surfaces on the spindle head and on the roll neck so as to primarily produce a positive engagement. The spindle head is provided with a clamping device for applying pressure to the wear plates and for clamping the spindle head on the roll neck for constructing the positively engaging connection as a play-free connection.

Connection between the spindle head of a gear-type or universal joint

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 rolling mill drive with spindles arranged axially slidably between pinions and work rolls. A joint of each spindle is releasably connected to the neck of at least one roll, particularly the work roll. At least the spindle joint connected to the work roll includes a coupling and uncoupling device, preferably an annular bayonet-type coupling device.
