Tamiya 70103 - TAMIYA UNIVERSAL GEARBOX

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.

Tamiya 70103 universal gearbox has a thin, compact, 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 we carry, giving you many options for your robot speed. The low-voltage motors run on 3-6 volts and draw up to a few amps, making them perfect candidates for the DRV8833 motor driver carrier. Motor overheating can be caused by excessive stalling, even at very low voltages. We recommend that you use stall-detection sensors, or just watch your robot, to make sure that it doesn't stall for more than a few seconds at a time.
