Abstract
A crown adjustment system for a 20-high (1-2-3-4) cluster mill of the type having upper and lower clusters each comprising a work roll, two first intermediate rolls, three second intermediate rolls, and four backing bearing assemblies. Each of the backing bearing assemblies of the upper cluster comprises a shaft supported along its length by saddles. Each of the saddles has a projecting ring through which the shaft passes. A plurality of bearing roll segments are journaled on the shaft between its respective saddle rings. A plurality of eccentrics are keyed to the shaft, each being located within one of the saddle rings supporting the shaft. Within the saddle ring of each saddle supporting the shaft there is an eccentric ring mounted on bearing rollers between its respective saddle ring and the adjacent keyed eccentric. The saddles of each of the shafts of the backing bearing assemblies of the upper cluster are equal in number and occupy the same saddle locations so that the saddles at corresponding saddle locations on adjacent shafts lie opposite each other. Those eccentric rings on the shafts of all four backing bearing assemblies of the upper cluster, which occupy the same saddle location, are interconnected by gears and are rotatable by a drive assembly at that saddle location. As a result, a single drive means for each saddle location can be used to effect the crown adjustment on all four backing bearing assemblies of the upper cluster.
