Centrifugal compressors are the key machines for compressing and conveying all kinds of gas in the chemical production. The main application fields are chemical and petrochemical, biological, medical, food and beverage, textile, automobile, mining and other industries.

New Yinye manufactures a complete set of rotor system (high speed gear assembly, high speed pinion shaft assembly, low speed pinion shaft assembly). The precision of the parts can reach DIN class 4, and can do tooth modification according to customers' design. ​New Yinye produced the gears with the minimum module M0.9, maximum OD 1500mm. The highest rpm for the big gear wheel is 3000r/min, and for high speed pinion shaft is 43500r/min.

The output pinion shaft manufactured by New Yinye is used for wind power 1.5MW, 3MW, 5MW, 6MW, 10MW reducers at home and abroad, with module from M9 to M30, no. of teeth from Z11 to Z25 and total length from 200 to 1000mm. We have mature production process of yaw output pinion shaft with monthly production capacity of 2000 pieces. At present, the most used material is 18CrNiMo7-6 and 17CrNiMo6.
