Understanding Movement Before Building It

The FIRGELLI Mechanisms Library brings together 1,929 animated examples across 40 categories, including linkages, gears, cams, escapements, couplings and motion-conversion systems. It helps users begin with the movement they need and compare how different mechanisms behave before committing to CAD or prototyping.

Published by FIRGELLI Automations, the resource combines visual demonstrations with plain-language guidance on force, geometry, wear, backlash, loading and duty cycle.

Why I saved this: I like how the animations make mechanical movement easier to understand while still reminding designers that smooth motion on screen does not guarantee performance under real loads. For design students, it provides a useful bridge between sketching movement and engineering it.

Worth considering: Have you selected a mechanism because it suits the required motion, or because you recognise it?

Try applying it: Compare three mechanisms for one moving feature in your project.

Design themes: Mechanisms, engineering design, prototyping, CAD, design for manufacture
