Device for driving a metal-forming machine tool includes a flywheel driving mechanism connecting to planetary wheel gearing with a drive shaft for a tappet drive.

摘要

First (20a) and second (20b) flywheel drives trigger (20a) a principal driving mechanism and overlay motion respectively. Each flywheel drive has a clutch-brake combination (21a,21b). An overlaid planetary gearing mechanism has a sun wheel (2), one or more planetary planet wheels (3) on a bridge (5) and an internal geared wheel (4) engaged with the planetary wheels.
