R17 series helical inline shaft gearboxes main features:

- Die-cast aluminum housings and motor flange;

- Cast iron foot and output flange;

- Ground gears (both 1st and 2nd stage);

- Long life lubrication;

R series helical gear reducers 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.

1.  high strength, compact: the box body is made of high strength cast iron. Gear and gear shaft adapts the gas carbonization, quenching and fine grinding process, therefore the bearing capacity of unit volume is high.

 

2.  long service life: Under the condition of correct type chosen (including choosing suitable operation parameters) normal operation and maintenance, the life of main parts of speed reducer (except wearing parts) should not be less than 20000 hours. The wearing parts include lubricating oil, oil seal and bearing  

3.  Low noise:  because main parts of speed reducer are processed, assembled and tested critically, therefore the noise of speed reducer is low;
