Scotch Yoko Mechanism

Educational Scotch Yoko Mechanism mechanism demonstrates relative motion between a crank rotation in degrees and a yoke translation in millimeters.

This unit is an example of slider-crank mechanism, for converting the linear motion of a slider into rotational motion or vice versa. The rotating motion of the crank generates the alternative linear motion of the piston. It is a reversible system.

The Scotch yoke (also known as slotted link mechanism) is a reciprocating motion mechanism, converting the linear motion of a slider into rotational motion, or vice versa. The piston or other reciprocating part is directly coupled to a sliding yoke with a slot that engages a pin on the rotating part.
