I want the details of Scotch yoke mechanism

abstract scotch yoke mechanism

The Scotch yoke (also known as slotted page 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. The location of the piston versus time is a sine wave of constant amplitude, and constant frequency given a constant rotational speed.Scotch yoke is a mechanism used to convert rotary motion into Sliding motion. This mechanism is obtained from an inversion of the double Slider crank chain.Double slider crank chain is a four-bar kinematic chain having 2 sliding Pairs and 2 turning pairs such that two pairs of the same kind are adjacent. The general version of the double slider crank chain is shown in fig. 1. two Die-blocks, P & Q, slide along slots in a frame, and the pins P & Q on the Die-blocks are connected by a page link PQ
