How does a differential work

How does a differential actually work? In this video, I break down the first principles behind differentials using a 3D printed demo model. Whether you’re into RC, engineering, fabrication, or just curious about how cars work, this is your complete reference guide to understanding differentials the right way. ⸻ Download the 3D Print Files Differential Model (3D Printable) Mega Ball Bearing (3D Printable) Download both at: https://www.curvlab.com Perfect for teaching, engineering demos, maker projects, RC builds, or hands-on learning. ⸻ Chapters 00:00 – Why differentials exist 01:00 – Fundamentals 02:50 – Bevel Gears 03:16 – Belt Drive 03:52 – Ball Bearings 05:28 – Center Differentials 06:19 – Differential in practice 06:30 – Download the 3D print files ⸻ Why This Matters Differentials are one of the most misunderstood parts of any drivetrain. Engineers, hobbyists, and enthusiasts all tend to visualize them differently. With this model, you’ll finally see what’s happening—no fluff, no jargon. ⸻ 🔗 Resources All 3D print files for the demo model are hosted here: https://www.curvlab.com Full RC chassis belt-drive video: https://www.youtube.com/watch?v=pdKnIPH3JQs Follow CURV LAB for more builds, tutorials, and design breakdowns. ⸻ If this video helped you… Like, comment, and share—especially if you’re a teacher, maker, engineer, or RC hobbyist.
