S series helical worm gearbox

SKU: helical worm gearbox ,right angle helical worm gear reducer Categories: ,


Helical worm gearbox is a new transmission machine designed & manufactured by worm- helical gear transmission principle.
1, helical worm gearbox, combined with international technical requirements, has the very high technology content;
2, save space, reliable and durable, bear high overload capability, power up to 250 kw;
3, low energy consumption, superior performance, speed reducer efficiency is as high as 95% above;
4, small vibration, low noise, high energy saving;
5, choose high quality forged steel material, semi steel housing, gear surface after high-frequency heat treatment;
