Four bar chain mechanism 3D model

cgtrader

The basic four-bar mechanism consists of four interconnected, bar-like links and four rotating pairs; visualize it in the provided animation. The immovable link (depicted as black) may be a physical bar but often represents a machine's frame, typically a substantial, irregular casting. Numerous mechanisms can be reconfigured into equivalent four-bar linkages. These versatile mechanisms have extensive applications in mechanical operations and are considered fundamental.
