ABSTRACT:
Dual, series ball screw and ball nut array for reciprocating a cable and a cutting mechanism utilizing the array. The first ball screw is stationary while the second is moveable, spaced apart and axially aligned with the first ball screw. Ball nuts are rotatably carried on each ball screw and the ball nuts are connected as by a tube. A drive means such as an hydraulic piston activator reciprocates the movable ball screw, thereby translating and rotating the second ball nut likewise the ball nut carried on the stationary ball screw. A pulley on either ball nut or on the connecting tube activates a cable connected thereto. A cutter connected to the cable is thereby reciprocated for slicing action.
