Crown structure for a three-pillar type press

摘要

A segmented crown structure for a three-pillar type press having a right and a left slide each suspended from the crown structure at four points. The crown structure is divided into central, right and left crowns. The central crown includes a motor for driving the press and a main shaft driven by the motor through a gear train. Also included in the central crown are four main gears driven by the main shaft through gear engagement. The right crown includes a shaft connected to the main shaft with a coupling and two main gears. Similarly the left crown includes a shaft connected to the main shaft with a coupling and two main gears. The two main gears in the right crown and two main gears in the central crown sided on the right suspend the right slide through four connection rods. Similarly the two main gears in the left crown and two main gears in the central crown sided on the left suspend the left slide through four connection rods.
