Visible Gear Train - Tamiya 89918 Double Gearbox (Clear)

The Tamiya 89918 Double Gearbox (Clear) provides a straightforward way to observe gear operation. The transparent case exposes the gearing so hobbyists can study interaction between wheels, pinions, and shafts while testing different inputs.

Construction Details and Observability

Built for clarity and function, the gearbox supports repeated assembly and inspection. Seeing gear engagement helps users learn about backlash, torque flow, and how different gear sizes change speed and force in a drivetrain.

Compatibility with Builds

This gearbox works with a number of Tamiya construction parts and small robotic platforms. It is a practical choice for educational setups, prototype testing, and hobby projects that benefit from visible mechanical feedback.

What motors pair well with this gearbox?

Low to medium speed DC motors used in Tamiya kits are a good match. Ensure the motor shaft and gearbox input are compatible and avoid overspeeding the gears.

Can I teach gear ratio calculations with it?

Yes. The clear housing makes it easy to count gear teeth and demonstrate how ratios affect speed and torque in real time.

How should I maintain the gearbox?

Keep gears clean, inspect for chipped teeth, and apply light gear lubricant if needed. Secure mounting and correct alignment reduce wear.

Is this suitable for prototype testing?

It is useful for low-power prototype testing where observing gear behaviour is important, but avoid high torque loads that exceed intended use.
