The Tamiya 72005 6-speed gearbox is a versatile, high-efficiency gearbox that you can build in one of the following gear ratios: 11.6:1, 29.8:1, 76.5:1, 196.7:1, 505.9:1, and 1300.9:1. Whatever your application, chances are that one of the configurations will do the job. A clutch gear protects the gearbox in high-gear-ratio configurations so that the gearbox does not rip itself apart if the output shaft gets stuck.
The low-voltage motors in the 6-speed gearbox 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.
The 4mm, round output shaft on this gearbox is compatible only with Tamiya’s sports tire set and narrow tire set.
For motor specs, see the Mabuchi motor RE-260 (#2295) data sheet (59k pdf). To compare all Tamiya gear box kits, see the Tamiya Gearbox Gear Ratio Comparison.
Note: The 6-speed gearbox is a kit; assembly is required. To use the kit in robotics projects, you need to connect the motors to your own robot controller.
