Rolling mill drive having a spindle with curved toothing

摘要

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.
