Abstract
A press drive device includes a connecting rod having input and output ends. A drive shaft mounts at first and second mounting points using first and second bearing mechanisms, to be rotatable about shaft axis W. Between the bearing points, the drive shaft includes a connecting rod bearing eccentrical in relation to the shaft axis and to which the input end connects. A motor includes a stator connected in a rotationally fixed manner. A rotor supported by a rotor hub is arranged radially within the stator. The rotor hub connects in a rotationally fixed manner directly to the drive shaft without using any step-up or step-down gear. The rotor, the rotor hub, and the drive shaft mount exclusively at the first bearing point and the second bearing point with no additional bearing points.
