Newest High Precision Helical Teeth Planetary Gear Reducer For 750W Servo Motor
The main transmission structure of planetary reducer is planetary gear, sun gear, internal gear ring and planetary carrier. Planetary gear reducer has the advantages of small volume, high transmission efficiency, wide deceleration range and high precision. It is widely used in the transmission system of servo motor, stepping motor, DC motor and other motors. Its function is to reduce speed, increase torque, reduce load and motor moment of inertia ratio on the premise of ensuring precision transmission.
