S Series Helical Worm gear reducer

S series helical worm reducer are different from ordinary worm gearbox ,the input side adopts a pair of helical reducing to come true reducing rotary speed and reducing hot's creating, meanwhile, it can gain larger transmission ratio. the structure are reasonable, can combine with R,MB series gearbox
