ROLLING STAND VERTICAL ROLL DRIVE UNIT Russian patent published in 2006 - IPC B21B35/14 B21B13/06 

FIELD: plastic working of metal in vertical and universal stands of rolling mill, namely mechanisms for transmitting rotation of motor to vertical rolls of rolling stand of strip rolling mill.

SUBSTANCE: drive unit of vertical rolls of rolling stand includes mounted in frame: electric motor, reduction gear with outlet shafts, spindles, mechanisms for lifting and descending. Spindles are joined through upper spline joints with outlet shafts of reduction gear and they are joined through lower spline joints with rolls of rolling stand. Mechanism for lifting and descending are provided with power cylinders for lifting and descending lower spline joints. Each mechanism for lifting and descending lower spline joints is in the form of pneumatic cylinder mounted along the same axis as shaft of spindle. Base of pneumatic cylinder is mounted on upper spline joint. Hollow rod of pneumatic cylinder is joined with lower spline joint with possibility of fixed its positions in spindle shaft.

EFFECT: lowered labor consumption, shortened time period for changing rolls.
