Patent

CA 2413831

A pinion for mounting rolls thereupon for reducing rod or wire in a rolling mill wherein said pinion has a pair of hydraulic pressure chambers formed therein which cause a threaded plug in a cavity in said pinion to undergo lateral movement to expand the pinion to engage a roll mounted on said pinion, and thence to cause a clamp to laterally clamp a roll against an abutment formed on the pinion to clamp the roll on the pinion once the plug has undergone lateral movement.

Un pignon pour montage sur rouleaux afin de réduire la tige ou le fil dans un laminoir, ledit pignon ayant une paire de chambres de pression hydraulique qui provoquent un bouchon fileté dans une cavité dans ledit pignon pour subir un mouvement latéral afin de dilater le pignon pour venir en prise avec un rouleau monté sur ledit pignon et, par conséquent, amener un collier à serrer latéralement un rouleau contre une butée formée sur la pignon pour serrer le rouleau sur le pignon une fois que le bouchon a subi un mouvement latéral.
