Question: 

Draw neat diagram of ‘scotch yoke mechanism’? Explain its
constructional features in brief.

Answer: 

 

Constructional Features of Scotch Yoke Mechanism:
[1] In this mechanism, two sliding pairs and two turning pairs are used. So it is an
inversion of Double Slider Crank Chain Mechanism.
[2] It consists of following types of links with relative motion as mentioned below;
Link 1 (B) – Fixed Link – Guide the Frame
Link 2 – Crank – Turning Motion – Rotates about Point B in Link 1
Link 3 - Slider -Sliding Motion
Link 4 – Fixed Link – Frame – Reciprocating Motion
[3] The inversion is obtained by fixing either the Link 1 or Link

[4] When the link 2 (which corresponds to crank) rotates about B as centre, the link 4
(which corresponds to a frame) reciprocates. It is used for converting rotary motion
into a reciprocating motion.
