PROBLEM TO BE SOLVED: To provide a driving mechanism of a crank press, which makes the structure of the press compact. SOLUTION: The driving mechanism of the crank press converts the rotational motion of a crank shaft 10 to the vertical motion of a slide 30 through a connecting rod 20, and is provided with a lifting cylinder 40 keeping the slide 30 lifted. The driving mechanism comprises an input gear 18 fitted to one end of the crank shaft 10, a casing 50 fixed to a press frame, a flywheel 62 rotated by a motor, a driving shaft 64 rotated by receiving the rotational torque of the flywheel 62, a speed reducer 70 connected to the output end of the driving shaft 64, and a coupling 77 connecting the output part of the speed reducer 70 to the input gear 18. The flywheel 62, the driving shaft 64, and the speed reducer 70 are rotatably supported by the casing 50. COPYRIGHT: (C)2008,JPO&INPIT
