<p>The invention provides a servo press machine including a slide (1) moved up and down by multiple crank structures, the machine which provides perfect synchronism between main gears (17a,17b) driving the respective crank structures and in which a compact, efficient power transmission structure can be implemented in a simple construction. In the servo press machine including the slide (1) moved up and down by the multiple crank structures, synchronous distribution gears (15a,15b) are driven by servo motors (21); the multiple main gears are driven in synchronism by the synchronous distribution gears (15a,15b); and each of the crank structures is driven by each of the main gears (17a,17b).</p> |
