METHOD OF EQUILIBRATION OF ROLLERS CELL DRIVING GEAR SPINDLE OF ROLLING MILL Russian patent published in 2008 - IPC B21B35/14 B21B31/00

Abstract RU 2323792 C2

FIELD: metallurgy.

SUBSTANCE: method includes the creating of compensating effort by hydraulic cylinder piston, which working cavity is fed by fluid under the pressure that cooperates with spindle in the gravity center. Depending on the removal value of the spindle gravity center from the geometrical rotation axis for getting the compensating effort, the fluid pressure is changed in the working cavity which is counterbalanced according to formula where G - the weight of spindle, D_sp - diameter of the hydraulic cylinder piston, c₀ - angular velocity, l₀ - the removal value of the spindle gravity center from the geometrical rotation axis.

EFFECT: it is provided the high longevity of independent elements of the driving gear and gear in general.
