PURPOSE:To increase the speed of a screw press so as to obtain ideal forging conditions and to improve productivity by rotating forward and backward a flywheel for a spindle by means of a motor contg. internally a flywheel and forward-backward revolving clutch and planetary reduction gears and providing a brake to the flywheel for the spindle. CONSTITUTION:The revolution of a driving shaft 14 is decelerated by the planetary reduction gears 30 when the air of the prescribed pressure is forced from A according to a forging operation to revolve forward the shaft 14. The revolution is then stored as kinetic energy from a low speed shaft 31 to the flywheel 32. This energy rotates a screw spindle 35 and a slide 38 is vertically moved by a nut 37 screwed to said spindle. The descending of the slide 38 stops when the kinetic energy of the flywheel 32 is thoroughly consumed by forging. The spindle flywheel 32 is then rotated backward by a friction plate 22 for the reversing clutch to raise the slide 38. The brake shoe 33 is provided to the flywheel 32 so that the spindle 35 can be stopped.
