Abstract: A pilger rolling mill with a roll stand moves linearly back and forth along a movement direction and includes a crank mechanism having a rotatably supported crankshaft with a crank pin and push rod. A first end of the push rod is pivotably fastened to the crank pin and a second end is pivotably fastened to the roll stand, so that during operation of the pilger rolling mill a rotary movement of the crankshaft is converted into an oscillating movement of the roll stand along the movement direction. A compensation shaft is rotatably supported about an axis of rotation and includes a distribution of mass that is not rotationally symmetrical relative to its axis of rotation and a counter-mass. The crankshaft and the compensation shaft are connected to one another by a transmission so that a rotation of the crankshaft leads to a rotation of the compensation shaft.
