DE 19959394 A UPAB: 20010726 NOVELTY - The device has a flywheel drive and a planetary gear with override transmission. The transmission is driven by the flywheel drive (20). Sun wheel (2) and ring wheel (4) have opposite directions of rotation. The planetary gear has at least one planet wheel (3) connected to the press ram drive. The sun wheel is connected non-turnable to a coupling shaft (14), and the ring wheel is either braked or connected to the override transmission via a coupling-brake unit (13). USE - Esp. mechanical forming press. ADVANTAGE - Planetary gear rpm can be switched on take-off side, esp. for selective switching between normal working process and creep speed motion, simplified drive unit, cheaper to manufacture.
