Ravigneaux Gear Set -> 4 Forward Gears and Reverse

This Ravigneaux gear set is a compact and lightweight planetary system, 3D-printed entirely from durable PLA. It is ideal for hobbyist and maker applications, offering a functional and educational model of a multi-speed gearbox.

Gearboxes like this are used in automatic car transmissions !!!

Key Features:

• 4 Forward Gears + 1 Reverse Gear: Designed to mimic real-world automatic transmission systems, it offers a total of five selectable driving modes.
• Encased by a Hollow Ring Gear: The external ring gear integrates and secures the entire assembly, ensuring a stable and efficient operation.
• PLA Construction: Lightweight and easy to manufacture, making it perfect for prototyping and experimentation.
• Use more durable Materials for high load applications
• Dual Sun Gear System: Includes a large and small sun gear, enabling complex speed ratio configurations in a compact footprint.
• Easy to Assemble: The design is modular and user-friendly, encouraging customization and exploration of mechanical principles.

Whether for educational purposes, functional use in small robots, or as a demonstration of mechanical engineering, this Ravigneaux gear set delivers impressive performance.

It’s a great example of how 3D printing can bring sophisticated gear systems to life for makers everywhere.
