The invention relates to a rolling mill, especially a swage rolling mill for heated operation, said rolling mill being provided with a pair of cylinders () which are vertically arranged with the central axes thereof (), can be adjusted in relation to each other, and are connected to at least one rotating drive () by means of cardan shafts (). The aim of the invention is to render the adjustment of the cylinders more favorable with lower displaced masses, to reduce friction and to improve lever arm relations. To this end, the rotating drive () for both cylinders () is fixed beneath the mill floor level () and is respectively connected to a fixed gearbox () and the cardan shaft () in a driving manner.

Rolling mill, especially a swag rolling mill, for heated operation

The invention relates to a torque support on oil collecting receptacles (') in a region of a paired connection of spindle heads and roll necks (&#x2032;) in rolling mill stands during adjustment thereof in both vertical and axial directions, with a respective attachment point on both upper and lower collecting receptacles (&#x2032;). The new torque support consists of a one-piece strip () having, in particular, a rectangular cross-section and formed of flection-resistant material, and which is pivotally connected at an upper end with the upper oil collecting receptacle () in a vertical plane by an articulated joint () and, in a region of its lower end (), is slidably guided in the pendulum plane in formlockingly compatible opening () of a guide link member () so that the distance and the inclination angle (&#x3b1;) change.

Torque support

A rolling mill drive with axially slidable spindles arranged between drive shafts and drive rolls, particularly between driven necks of pinions and drive necks of rolls. The spindle heads of each spindle are each provided with a wobbler with a curved toothing and coupling sleeve having an internal toothing surrounding the wobbler. The coupling sleeve is connected to the pinion neck or to the roll neck. The spindle is guided between the coupling sleeves by means of at least one support element arranged in the region of the spindle axis and an axially adjustable pressure plunger. The internal toothing of the coupling sleeve extends beyond the curved toothing of the wobbler and has at least a supporting length which corresponds to the length of the possible axial displacement of the spindle.
