Four-bar mechanism by Catia v5 DMU Kinametics 3D model

cgtrader

A basic four-bar mechanism consists of four bar-like links and four rotating pairs, as demonstrated in an animation. Typically, the stationary link (depicted as black) is a machine's frame, often a large, irregularly shaped casting. Numerous mechanisms can be simplified to equivalent four-link systems, which are widely used in mechanical processes due to their fundamental nature.
