JH series gear reducer for development machines

This kind of gear reducers are the main transmission equipment for development machines at coal mine. They are divided into two categories as rock cutting and coal cutting. The gear reducer is installed at the cutting bottom of the development machine. The power of the main motor is transmitted to the cutting head through this gear reducer. Our JH series gear reducer is smaller, lighter, and more reliable and stable compared to similar gear reducers of other Chinese gear makers. Normally, the gear reducer is designed to two-stage planetary structure, which is favorable for coaxial arrangement of input shaft and output shaft. Flange connections are designed for both input and output shafts, which is convenient to connect the electric motor and the cutting head. 

Power range of the gear reducer: 100 kW~318 kW
