Mechanical power transmission coupling
Abstract
Abstract A MECHANICAL POWER TRANSMISSION COUPLING STRUCTURE PARTICULARLY SUITABLE FOR USE WITH A ROLLING MILL HAVING A ROLL WITH A NECK OR DRIVE SHAFT CONNECTED TO THE ROLL, IN WHICH THE COUPLING STRUCTURE INCLUDES LANDS ON THE ROLL NECK AND A CONNECTOR WITH A BORE HAVING CORRESPONDING LANDS THEREIN FOR MOUNTING ON THE ROLL NECK. FLUID OPERATED PISTONS DISPOSED IN CYLINDERS IN THE NECK ENGAGE THE LANDS ON THE ADAPTER TO FORM A FIRM CONNECTION BETWEEN THE COUPLING AND THE ROLL. THE FLUID, WHICH IS PREFERABLY HYDRAULIC, IS TRANSMITTED TO THE CYLINDERS IN THE ROLL NECK THROUGH PASSAGES IN THE ROLL. WHEN THE PISTONS ARE ACTUATED, THE LANDS ON THE ROLL NECK SEAT ON THE LANDS OF THE ADAPTER, THEREBY ELIMINATING OR MINIMIZING MOVEMENT BETWEEN THE PARTS AND PREVENTING FRETTING, EXCESSIVE WEAR, AND BACKLASH.
