Details

Extreme torque from a standard size servo....easily done with the CM-400-180 Channel Mount Servo Gearbox Kit. This device increases the stated torque of your servo by adding another set of final drive gears. By incorporating threaded side mounts you can now easily attach these servo gearboxes to numerous ServoCity products including tubing and channel; making it easier than ever to incorporate a servo gearbox into a custom pan & tilt, mechanical device, or robotic structure. Utilizing an external potentiometer on the final output shaft the original amount of rotation from the servo remains. The structure is machined from high-strength 6061-T6 anodized aluminum. The hardened 1/2” stainless steel final output shaft is supported by dual ABEC-5 precision ball bearings that not only allow extremely smooth operation but can also support up to 200 pounds of vertical and horizontal load.  The main spur gear is bolted to the drive hub so that all power transfer is direct without the possibility of slipping. With five optional gear ratios, you are sure to find the right combination of torque and speed for your project. Gear ratios can easily be changed if you need to vary the torque or speed.  The CM-400-180 kit will come with full assembly instructions. Servo not included. Patented.

Note: The CM-400-180 kit, when assembled, will allow the final shaft to rotate approximately 90 degrees using a Hitec digital servo with stock programming. To increase the rotation (when using a digital servo) you can use a Hitec servo programmer to re-program the endpoints. Maximum achievable rotation is approximately 180 degrees. If you are not comfortable soldering and handling delicate parts, we would suggest purchasing a fully assembled Servo Gearbox.

To figure the torque output use the following formula:
Servo Gearbox Torque = Servo Torque x Gear Ratio
Example: An HS-425BB servo that produces 57 in-oz of torque at 6V matched with a 5:1 ratio.
57 X 5 = 285 in-oz in the Servo Power Gearbox

To figure the speed output use the following formula:
Servo Gearbox Speed = Servo Speed x Gear Ratio
Example: An HS-425BB servo that goes 60° in .16 seconds at 6V matched with a 5:1 ratio.
.16 X 5 = 60° in .80 seconds in the Servo Power Gearbox

In closed loop control, the system is self adjusting. Data does not flow one way, it may pass back from a specific amplifier (such as velocity or position) to the start of the control system, telling it to adjust itself accordingly. Many physical systems are closed loop control at the lowest level since the data about velocity and current position modify the output (also position) at consistent rate.  Click here to learn more about closed loop systems.
