Abstract
The disclosure of the present invention relates to a compensating counterweight system used in a cold pilger step-by-step type seamless tube rolling mill reciprocated by a crank assembly. The crank assembly includes first and second compensating mass devices which are arranged to rotate coaxially on a single crank shaft in opposite directions relative to each other. The two mass devices are kinetically connected through a bevel gear drive set which causes the second compensating mass device to rotate in an opposite directon to the first compensating mass device.
