CRANK PRESS DRIVE Russian patent published in 1994 - IPC

FIELD: pressing. SUBSTANCE: transmission of the electric motor shaft is transmitted to the press crank actuator through a V-belt transmission, flywheel, coupling, two pairs of helical gears. The angle of tooth helix to the longitudinal axis of gears is different in each pair. It is larger in the pair adjoining the flywheel, and lesser - in the opposite pair. Owing to it, the torques transmitted by the pairs of gears and caused by the production loads applied to the press slide get balanced. EFFECT: facilitated procedure. 2 dwg, 1 tbl
