Tamiya 72004 Worm Gearbox Kit
The primary feature of this high-efficiency gear box is a worm gear, which locks the output shaft whenever the motor is not turning. The high gear ratios of 216:1 or 336:1 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.
