Abstract
A drive assembly for axially adjusting at least one roll of the upper and lower pairs of first intermediate rolls of a cluster mill of the 20-high (1-2-3-4) type. The drive comprises a first horizontally oriented rack connected to one of the first intermediate rolls by a link and universal joint assembly. As least one idler gear, with its axis horizontally oriented, is meshed with the first rack. A second rack horizontally oriented is affixed to the piston of a horizontally oriented hydraulic cylinder. The second rack and the hydraulic cylinder are in parallel spaced relationship to the first rack. The second rack is meshed with the at least one idler gear so that axial movement of the piston and second rack in the hydraulic cylinder will result in axial movement of the first rack via the at least one idler gear to axially shift the at least one roll. Such a drive can have its first rack attached to a pair of rolls by a universal joint assembly and a link for each roll so that the drive can simultaneously axially shift both rolls. Four such drives can each be used to axially shift the four first intermediate rolls independently. In any of the embodiments the second rack may have a …
