High Torque Gearbox Helical Gear Reducer With Cast Iron , Solid Shaft

R series Helical gear motor 

R series helical gear motor is designed based on modularization , which bring many difference kinds of 

combinations ,mounting types ,and structure designs .The detail classification of ratio can meet various 

of working condition .High Transmission efficiency ,Low energy consumption, superior performance . The 

hard tooth surface  

gear use the high quality alloy steel , the process of carburizing and quenching, grinding ,which give it 

follow characters : Stable transmission , low noise and temperature  ,high loading ,long working lift .  

Wide application ,specialize in Metallurgy ,Sewage treatment, Chemical Industry , Pharmacy ,Agriculture 

equipment and Oil industry .
