Tamiya Planetary Gearbox Set

The Tamiya Planetary Gearbox Set – Technicraft Series is a precision-engineered kit designed for mechanical exploration, robotics, and educational projects. Its planetary gear system mimics the motion of planets orbiting the sun, offering both efficiency and versatility.

This kit includes:

• RC-260 motor (built into the gearbox)
• Durable molded gears and case
• Crank plates and joints for varied motion
• Assembly tools and instructions

Users can configure eight gear ratios: 4:1, 5:1, 16:1, 20:1, 25:1, 80:1, 100:1, and 400:1. The modular design allows learners to experiment with torque, speed, and mechanical output. The sun gear and surrounding planetary gears rotate within an internal ring gear, delivering smooth, locked motion when needed.

Perfect for Grades 6 and up, this gearbox supports curriculum goals in engineering and technology. It encourages design thinking, problem-solving, and hands-on learning. Whether used in classrooms, maker spaces, or hobby builds, it’s a reliable tool for creative mechanical projects.
