Scotch yoke

thingiverse

The Scotch yoke efficiently converts rotational energy into precise linear movement, serving as a prime example of a slotted link mechanism. A wheel with a peg offset from its center drives the yoke's lateral motion, influenced by the slit size and peg position on the wheel. This 3D printable model is primarily designed to visually demonstrate the Scotch yoke's functionality. Optimized designs can minimize play and friction by incorporating sliding and rotating bearings. In this model, the user can manually rotate the wheel to move the yoke left or right. For a controlled linear motion with variable speed near maximum extension, coupling the wheel directly to a motor or using a gear set would be effective.
