Abstract
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.
