MECANISME DE REGLAGE AXIAL A GRANDE PUISSANCE DES CYLINDRES D'UN LAMINOIR

摘要

A heavy duty axial adjustment mechanism for a rolling mill roll neck which is rotatably supported in a radial bearing contained in a chock. A rolling element thrust bearing has its inner race fixed axially in relation to the roll neck. The outer thrust bearing race is axially confined between separable retainer components which are interconnected by fasteners. The retainer components each have external adjusting threads in engagement with internal adjusting threads on the chock. Rotation of the interconnected retainer components imparts axial adjustments to the roll neck relative to the chock without subjecting the fasteners to damaging thrust forces.
