helical worm gearbox features:  

1. S series helical worm gearbox is the combination transmission structure of helical gears and worm wheels,right angle shaft output and steady running.

2. Little vibration and low noise, with large transmission ratio,helical worm gearbox the transmission efficiency is lower than helical gearbox.

3. The material of gears is 20CrMnTi alloy steel and the hardness can reach to HRC58°~ 62 after tempering , cementiting , quenching etc. heat treatment. All the gears are processed by accurate grinding and the precision can reach to grade 6~5°

4. Helical-worm reducers have been mainly used in petrochemical machinery, mine and construction machinery, metallurgy, printing and packaging machinery, etc.

S series Helical-worm reducers are available in the following designs:
(1) S Foot mounted helical worm gearbox with solid shaft

(2) SA  helical worm gearbox with hollow shaft

(3) SAZ  Small flange mounted helical worm gearbox with hollow shaft

(4) SA (S,SF,SAF,SAZ)  Assemble users' motor or special motor, flange is required

(5) SF  Flange mounted helical worm gearbox with solid shaft

(6) SAF  Flange mounted helical worm gearbox with hollow shaft

(7) SAT  Torque arm mounted Helical-worm reducers with hollow shaft

(8) S (SF,SA,SAF,SAZ)   Shaft input Helical-worm reducers

(9) SA (S,SF,SAF,SAZ)R  Combined Helical-worm reducers

(10) SA (S,SF,SAF,SAZ)S  Shaft input combined Helical-worm reducers

Helical worm gearbox Applications:

Helical worm gearbox are widely applied in electricity, coal, cement, metallurgy, harbor, agriculture, shipping, lifting, environment protection, stage, logistic, weaving, paper making, light industry, plastics and other regions
