R series helical gear reducer 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 following characters: stable transmission, low noise and temperature, high loading, long working lift. Wide application, specialize in Metallurgy, Sewage treatment, Chemical Industry, Pharmacy, Agriculture equipment, Oil industry, Belt Conveyor, Food machine, Mixer, Mixing machine, Automatic production line,Packaging, Material handling, Mechanical-electromechanical industry etc.
