Abstract: A drive module of a machine having a turret adjacent the upper end and a motor adjacent the lower end. The turret is driven by the motor to move between different stations of the machine by the controlled rotation of the turret about an axis of rotation. The motor includes an upwardly directed output shaft which is in generally axial alignment with the axis of rotation of the turret. An outer housing is disposed between the turret and motor, and the output shaft of the motor is connected to an inner housing disposed for rotation within the outer housing. An elongate shaft extends axially through the inner housing and is connected with the turret to transmit movement of the shaft to the turret. A force transmitting member is connected to the inner housing and to the elongate shaft for transmitting rotational movement of the inner housing to the elongate shaft, and for permitting axial movement of the elongate shaft relative to the force transmitting member and the inner housing.

Abstract: A machine including a system for moving one member into engagement with another and to apply a high clamping force thereto. The system includes an electrically operated pump and an associated cylinder assembly. The cylinder assembly includes a housing having first and second chambers, each having actuating fluid therein. A piston is located within the housing and is coupled to one member. A ballscrew and associated nut are located within the housing coupled to the piston and arranged to move the piston in either of two opposite directions under power from an externally located electrical servomotor. When the piston is moved in one direction it carries the associated member into engagement with the other member and also causes actuating fluid to flow from the second chamber into the first chamber. The pump is arranged to provide additional actuating fluid to the first chamber for applying a clamping force directly to the piston, and not to the ball screw and nut.
