STEM Lab Variator - Mechanical CVT Transmission 3D Wooden Puzzle

Variator by Ugears - Educational Mechanical CVT Model STEM Lab Series

Unlock the secrets of mechanical power transmission with the Variator from the Ugears STEM Lab collection. This hands-on educational model is an operational scale reproduction of a Continuously Variable Transmission (CVT). Discover how vehicle drivetrains alter gear ratios smoothly without discrete steps, an engineering breakthrough used in modern cars, scooters, and snowmobiles.

Hands-On Experience with CVT Mechanics

Transforms a complex physics topic into clear visual mechanics:

• Manual Ratio Shifting: Move the selector fork lever to slide the drive belt across opposing cone pulleys, observing immediate shifts in rotational output speed.
• Open Skeletal Frame: Every step of torque transfer—from the planetary reduction drive to the conical friction pulleys—is visible to examine friction drive mechanics.
• Foot Pedal Control: Press the pedal mechanism to operate the shifting fork, demonstrating gear ratio changes in real vehicle transmissions.

Augmented Reality Learning (AR & Study Guide)

More than a wooden puzzle, it serves as an interactive mechanics masterclass:

• Augmented Reality App: Scan your completed Variator using the Ugears AR app to see how CVTs function within modern automotive transmissions.
• Interactive Study Guide: Access historical backgrounds (Milton Reeves, 1879), torque equations, and lab assignments via the included QR code.
