ABSTRACT:
The invention relates to an improved device for moving and axially adjusting horizontal rolls of a section for rolling mill stand, comprising an axial thrust bearing mounted in the envelope of a casing blocked on an element of the stand, a sleeve mounted for axial slide and fast with the outer race of the bearing, the sleeve being blocked in rotation in the envelope of the casing; a screw mechanism for adjusting the position of the sleeve with respect to the envelope of the casing comprising a thread on an outer part of the sleeve on which are screwed two pinion-nuts, two end stops formed on the casing, two shafted pinions pivoting in the casing each contiguous with a stop and meshing with a respective pinion-nut, the two pinion-nuts being provided on their opposite face with a dog-clutch. The shafted pinions may be controlled by motors having reversible rotation, and associated with pulse counters.
