The invention relates to a press drive device (21) for a press (10), comprising a connecting rod (49) that has an input end (48) and an output end (50). The output end (50) is preferably coupled to a toggle joint (55) of a toggle mechanism (51). A drive shaft (35) is mounted so as to be rotatable about a shaft axis (W) and includes a connecting rod bearing (46) that is eccentric in relation to the shaft axis (W). The input end (48) of a connecting rod (49) is mounted on the connecting rod bearing (46). At least a first drive housing (24) and a second drive housing (25) are provided on axially opposite sides of the connecting rod bearing (46). The drive shaft (35) projects into both drive housings (24, 25). An electric driving motor (30), preferably a torque motor, is arranged in at least one of the drive housings (24, 25) and comprises a stator (65) which is connected in a rotationally fixed manner to a peripheral wall (26) of the drive housing (24, 25), said peripheral wall (26) being located coaxially around the shaft axis (W). A rotor (66) supported by a rotor hub (67) is arranged radially within the stator (65). Mounting space inside which at least part of a braking device (31) can be arranged is provided between the shaft axis (W) and the rotor (66). |
