Tamiya 72008 4-Speed Worm Gearbox Kit
The primary feature of this gearbox is a worm gear, which locks the output shaft when the motor is not turning. Its high gear ratios of 84:1, 216:1, 555.4:1, and 1428.2:1 make this gearbox appropriate for small walking robots, lifting mechanisms, and other applications where high torque is desired.

Notes:
- 1
- A theoretical speed of the gearbox output shaft can be computed by dividing this speed by the gear ratio.
- 2
- This is the no-load current of the motor when disconnected from the gears in the gearbox; the no-load current of the entire gearbox with the motor connected will be slightly higher and will vary depending on the gear ratio.
- 3
- A theoretical torque of the gearbox output shaft can be computed by multiplying this torque by the gear ratio.
