Abstract
The drive movement of the press ram (7) is derived without a crank shaft directly from an eccentric body (5) in the form of an eccentric disc connected to the planetary wheel gear (1-4). A gear element (3,4) of the planetary wheel gear is connected to the eccentric body which supports at least one coupling element (6) for driving the press ram. The eccentric disc is connected to the planetary wheel support (4) or an annular wheel (3) of the planetary wheel gear which has an extra drive (11,12) for varying the speed of the press ram. ADVANTAGE - The compact drive mechanism provides better dynamic and static properties.
