ABSTRACT:
A driving apparatus for a vertical rolling mill comprises a vertical electric motor mounted on a frame which has a hollow rotary shaft therein supported by a bearing and surrounding a portion of an intermediate shaft. The upper end of the intermediate shaft extends through the hollow rotary shaft and connects to a first universal joint disposed axially above the motor, and which engages the upper end of the hollow rotary shaft. The torque of the hollow rotary shaft is transmitted to the vertical roll through the first universal joint of the intermediate shaft, and a second universal joint.
