Abstract
An arrangement for inclined rolling of tube-shaped or bar-shaped rolling products comprises at least two rollers adapted to receive therebetween a rolling product so as to determine a longitudinal axis of the rolling product, the rollers are driveable and are rotatable about said longitudinal axis. The rollers have roller axes inclined at an inclination angle relative to the longitudinal axis, the roller axes being inclined in such a plane which, when considered in or against the longitudinal axis, extends parallel to the longitudinal axis at a radial distance from it, and a driving unit for driving the rollers. The driving unit includes a sun gear and drive gears provided with an axis-offset bevel gear toothing and surrounding a respective one of the roller axes, the drive gears engaging with the sun gear so that the rollers are driven by the sun gear through the drive gears.
