Tamiya 70167 Single Gearbox (4-Speed) Kit
 
|
The single gearbox is perfect if you like the gear ratio options of the 70168 double gearbox but need just one motor or added flexibility in positioning multiple output shafts. Available gear ratios are: 12.7:1, 38:1, 115:1, or 344:1.

The Tamiya 70167 single gearbox is essentially half of the Tamiya 70168 double gearbox. The kit can be built with gear ratios of 12.7:1, 38:1, 115:1, and 344:1. There are two possible output axle locations (for any given gear ratio, only one output location is possible).
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 Pololu low-voltage dual serial motor controller. The Pololu Orangutan LV-168 robot controller, which incorporates these low-voltage motor drivers, would be a great control center for a robot using these motors. 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.
For motor specs, see the Mabuchi motor FA-130 (#18100) data sheet (58k pdf). To compare all Tamiya gear box kits, see the Tamiya Gearbox Gear Ratio Comparison.
Note: The single gearbox (4-speed) is a kit; assembly is required. To use the kit in robotics projects, you need to connect the motors to your own robot controller.
