Scotch yoke Mechanism
Scotch yoke Mechanism Introduction : Scotch Yoke Mechanism is a reciprocating mechanism that converts rotational motion to reciprocating motion or vice-versa. It is also known as slotted link mechanism . This mechanism is an inversion of Double Slider Crank Chain . It can be used to either convert linear motion of slider to rotational motion of crank or it can be used to convert the rotational motion of crank to linear motion of a slider. This mechanism is commonly used in control valve actuators in high-pressure gas and oil pipelines. Concept of mechanism : The Scotch yoke 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. The shape of the motion of the piston is a pure sine wave over time given a constant rotational speed. Scotch
