WORKING STAND OF ROLLING MILL Russian patent published in 1998 - IPC

FIELD: rolled stock production. SUBSTANCE: stand includes frames and screwdown apparatus with drive mechanism having high-speed cylindrical gearing and low-speed cylindrical gearing mounted in separate casings arranged in different height levels. Casing with high-speed gearing is mounted on lateral surfaces of frames. Casings with low-speed gearing are mounted onto upper ends of frames. Vertical electric motors are arranged on said casing with high-speed gearings. Said high-speed gearings are joined with low-speed gearings by means of clutches with intermediate shafts. Said electric motors are joined with high-speed gearing by means of gear wheels. Gear wheels of low-speed gearings are joined with screwdown mechanism by means of splined joints. Separate gear wheel with connection and disconnection mechanism is provided for mechanically synchronizing operation of screwdown apparatus. EFFECT: reduced vertical dimension of stand, lowered height of building for rolling shop, possibilities of using crane with less power and height, enlarged manufacturing possibilities for making, assembling and mounting drive unit of screwdown mechanism of stand. 1 dwg
