With metal planetary gearbox, largetorque, long life, high stabiity, lownoisel. The planetary transmission structure ischaracterized by multi-point contact, high efficiency,stability and torsion Gear has powder metallurgy and 45 # steel pipe tooth double process for choice, after high temperature quenching,wear reresistance. According to the number of stages,the transmission efficiency will also bedifferent. Match motor parameters can be customized,support match encoder andwire and connector.
