How to Achieve Massive Speed Reductions with Planetary Gears (160:1 and Beyond!)

Schedule time with Corey: https://mentoredengineer.com/consulting/ Need serious torque and ultra-low speed? In this video, I show you how to achieve extreme speed reductions — like 160:1 ratios — using multi-stage planetary gear systems. Whether you’re building a robot, winch, or DIY drivetrain, this technique gives you huge mechanical advantage in a compact form. I walk through the design principles, explain how to stack planetary stages effectively, and highlight common pitfalls to avoid. You’ll see a real-world example of a high-ratio gearbox in action, and trust me — it’s awesome. 🌀 Planetary gear basics and math ⚙️ Multi-stage stacking for massive reductions 💥 Example: 160:1 3D printed gearbox 🛠 Design tips for strength, size, and simplicity 🎉 Special thanks to Gear Down for What?    • High Torque High Speed 3D printed 160:1 Co...   for the super awesome 3D printed gearbox featured in this video!
