ABSTRACT:
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.
