Abstract
This invention is intended to provide a large-capacity servo press apparatus driven by multiple motors, the servo press apparatus enabling a drive at a high efficiency and with reduced torque pulsations in a simple structure. The disclosed servo press comprises a slide that is moved up and down by a plurality of crank structures (including eccentric rings and connecting rods), main gears that drive the crank structures, a plurality of drive gears interlinked with the main gears directly or indirectly, intermediate gears interlinked with the main gears directly or indirectly, and servo motor sets connected to drive shafts to drive the drive gears. In each of the servo motor sets, a plurality of servo motors are directly connected to each servo motor shaft.
