The Universal Gear Box works well in a variety of applications and can be mounted several ways. A hex shaft and a threaded shaft are included to give the builder flexibility in design. The plastic gears and metal gear box are all high quality. A FA-130 motor has also been included.
Unlike the other gearboxes in Tamiya’s series, the universal gearbox has a thin metal frame, making it the smallest Tamiya gearbox. The final two gears are metal, making for a tough output. A worm gear allows for the high gear ratio options of 101:1, 269:1, and 719:1.
The main output shaft can be oriented in four different directions, and a small, auxiliary output shaft turns perpendicularly to the main output shaft.
The output shafts are 3 mm hexagonal axles that are 10 cm (about four inches) from tip to tip. The axles work with any of the Tamiya wheels, giving you many options for your robot speed. The low-voltage motors run on 3-6 volts and draw up to a few amps. Motor overheating can be caused by excessive stalling, even at very low voltages. We recommend that you make sure that it doesn’t stall for more than a few seconds at a time.
Tamiya makes a variety of gearboxes that are perfect for building small robots.The following table shows the different gear ratios supported by each model to help you select the Tamiya gearbox that best fits your needs.
