parallel motion
Quick Summary
Parallel motion refers to a mechanism designed to reproduce motion parallel to itself, essentially creating straight-line motion. In mechanical engineering, this is achieved through a system of connected links, often made of metal, joined by pin joints, sliding joints, or ball-and-socket joints.12
A common example is the four-bar linkage, which can convert uniform rotary motion into non-uniform rotary motion or continuous rotary motion into oscillatory motion. This type of mechanism is fundamental in machine construction for its ability to create constrained and determinate movements.2
