รายละเอียดสินค้า: Tamiya 70110 4-Speed Crank-Axle Gearbox Kit

This gearbox has four possible gear ratios, including the highest gear ratio of Tamiya’s gearbox series, 5402:1. The other options are 126:1, 441:1, and 1543:1. This gearbox also features a worm gear, which locks the output shaft when the motor is not turning.

 

Overview

The Tamiya 4-speed crank-axle gearbox has four possible gear ratios, including the highest gear ratio of Tamiya’s gearbox series, 5402:1, as well as 126:1, 441:1, and 1543:1. This gearbox also features a worm gear, which locks the output shaft when the motor is not turning. A clutch gear prevents the gearbox from destroying itself in case the output shaft gets stuck. The kit comes with all parts necessary to build the gearbox in any of the four possible configurations.

  - 70110 4-speed crank-axle gearbox  — This gearbox is solid gray and comes packaged in a box.

  - 89916 4-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.

 

To compare all Tamiya gear box kits, see the Tamiya Gearbox Gear Ratio Comparison.

 

Note: The 4-speed crank-axle 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.

 

General specifications
  - Typical operating voltage:  3 V 
  - Gear ratio options:  126:1, 441:1, 1543:1, and 5402:1, 
  - Free-run motor shaft speed @ 3V:  12300 rpm1 
  - Free-run current @ 3V:  150 mA2 
  - Stall current @ 3V:  2100 mA 
  - Motor shaft stall torque @ 3V:  0.5 oz·in3 
  - Color:  gray 

 

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.
