What is the Cast iorn helical worm gearbox?
S series helical-worm speed reducer adopts the helical gearworm wheel type to make the structure more reasonable.The series not only has higher transmission efficency and loading capability than those of single-stage worm wheel transmission, but also reduces space.Moreover,udner the close volume,the series can obtain higher transmission ratio and is more favorable for equipment setting. The product can be combined with various reducers and variators to meet the different requiements.
