24V 670RPM 414kgfcm AmpFlow DC Motor with Speed Reducer

We carry another famous AmpFlow heavy-duty, low-cost motor with gearhead as speed reducer. This is the famous motor for heavy duty combat robot.

This speed reducer uses a unique three-stage chain-and-sprocket mechanism that reduces cost while still maintaining high torque capacity.

This unit provides speed reduction and torque multiplication, and it's an easy way to "bolt-in" the AmpFlow motors. The speed reducers are made with a three-piece aluminum case that has been precision CNC machined. A total of six sprockets, three roller chains, and five bearings comprise the mechanism. The long output shaft makes it easy to mount pulleys, sprockets, gears, or wheels in the required position. Care was taken to make this unit as compact as possible. The overall dimensions are 6 inches x 3 inches x 2 inches. But the motor is recessed slightly into the reducer, so the net length added to the motor is only 1.78 inches.
The speed reducer uses a unique arrangement of roller chains. This results in torque and efficiency comparable to gear-type reducers at just 1/2 or even 1/3 of the cost of high-torque, geared speed reducers. There is slightly more noise, but these units are ideal when silent operation is not required.

The hardened output shaft is 3/4-inch diameter and 2.2 inches long. It has a 1/4-inch keyway and a 5/16-24 tapped hole. It is fixed to the sprocket with a hexagonal spline to strengthen the connection between the shaft and sprocket.

A single stage of roller chain reduction is generally considered to be about 98% efficient. Add in some friction from the five bearings and we are at about 90% efficiency.
