Converting two way linear motion into one way rotation 3




Input: blue screw having two threaded portions of opposite hands.

Output: glass gear having two ratchet wheels.

Two red bushes create revolution joint with the output gear and helical joints with the screw.

Reciprocate linear motion of the screw makes the two bushes oscillate in opposite directions. Ratchet mechanisms (two blue

pawls) convert motions of the two bushes into one way rotation of the output gear.

Using ball screw drives and roller overruning clutches instead of lead screw drives and ratchet mechanisms gives better output motion.
