Press Drive Device for a Press, and Press Comprising a Press Drive Device

Press (10) comprising:

• a press frame (12) which supports a slide (11) in a manner so as to be movably guided in a stroke direction (H),
• at least one toggle lever linkage (51) that comprises a first toggle lever (52) and a second toggle lever (53), the first toggle lever (52) and the second toggle lever (53) are connected to each other via a link joint (54), wherein the first toggle lever (52) is hinged to the press frame (12) and the second toggle lever (53) is hinged to a pressure point (56), and
• at least one press drive device (21) comprising:
• a connecting rod (49) that has a driving end (48) and an driven end (50),
• a drive shaft (35) that can be rotated about a shaft axis (W) and comprising a connecting rod bearing (46) that is eccentrically arranged relative to the shaft axis (W) and on which the driving end (48) of the connecting rod (49) is supported,
• at least one electric driving motor (30) comprising a stator (65) and a rotor (66),
• a rotor hub (67) supporting the rotor (66), said rotor hub being connected to the drive shaft (35) in a rotationally fixed manner,
• a first bearing mechanism (37) provided at a first bearing point (36), said mechanism supporting the drive shaft (35) on a first bearing part (41), and with a second bearing mechanism (40) provided at a second bearing point (39), said second bearing mechanism supporting the drive shaft (35) on a second bearing part (42), wherein the first bearing point (36) and the second bearing point (39) are arranged on axially different sides of the connecting rod bearing (46), and wherein the rotor (66) and the rotor hub (67) of the at least one driving motor (30) are supported only via the first bearing mechanism (37) at the first bearing point (36), and/or the second bearing mechanism (40) at the second bearing point (39),
• wherein a driven end (50) of the connecting rod (49) is connected to the link joint (54).
