The S series helical worm gear reducer is one of the 4 series of helical gear reducers. We use high-rigidity cast iron as material of its housing, which has a large bearing capacity. Its internal hard tooth surface gear is made of high-quality alloy steel, the surface is carburized and quenched and hardened, the tooth surface hardness is as high as 58-62hrc, and the tooth surface grinding accuracy is as high as 56. The worm gear part is made of wear-resistant high-quality copper, with fine grinding teeth, smooth transmission, low noise, large bearing capacity, low temperature rise and long service life.
From the box body to the internal gear, Shengjie adopts a completely modular structure design on S series helical worm gearbox, which is suitable for mass production and flexible selection.
The model of this type gearbox is divided in the form of decreasing torque. Compared with the traditional equal-proportion division, it can better meet the requirements of customers and avoid power waste.
Different internal structures of 4 series helical gear reducer:
S series helical worm gear reducer are divided into several basic series based on mounting forms: SF series ,SA series, SAF series, SAT series, SAZ series. The speed ratio of S series reducer ranges from 9.96 to 244.74, the torque ranges from 43Nm to 4200Nm, and the input power can reach up to 22KW.
