Drive system for a rolling mill

The invention concerns a drive system for a rolling mill, especially for a cold pilger rolling mill with at least one roll frame movable back and forth, at least one crank drive which has a crank arm with a counterweight for at least partial compensation of the inertial forces produced by the mill frame, a drive and a connecting rod which articulates the mill frame and the crank arm with one another and at least one counterweight which is eccentrically rotatable and serves to compensate the inertial forces and/or the moments of inertia. To achieve an efficient balancing of the inertial forces with a simple construction of the drive system, the invention provides that at least one counterweight is rotatably driven by a separate rod independently from the drive of the crank drive.
