Tamiya 70093 3-Speed Crank-Axle Gearbox Kit
 

Tamiya’s 3-speed crank-axle gearbox looks very much like half of the twin-motor gearbox
(with an added gear ratio option).
This compact gearbox can be built in one of three gear ratios
(17:1, 58:1, and 204:1), and is Tamiya’s cheapest, general-purpose gearbox.
 

The Tamiya 3-speed crank-axle gearbox is essentially half of the twin-motor gearbox.
The kit comes with enough parts so you can built the gearbox in any of three gear ratios (17:1, 58:1, and 204:1).

Color options

  • 70093 3-speed crank-axle gearbox  —  This gearbox is solid gray and comes packaged in a box.
  • 89914 3-speed crank-axle gearbox  —  This gearbox is clear and comes packaged in plastic bag.

Complementary products

The output shafts included in this kit 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 and
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. For motor specs,
see the Mabuchi motor FA-130 (#18100) data sheet (58k pdf).

Note that you can replace the motor in this kit with a lower-current, higher-voltage motor
if you want to use this gearbox with controllers such as the qik 2s9v1 dual serial motor controller,
TB6612FNG dual motor driver carrier, or Baby Orangutan B-328 robot controller.
