S Series Helical Gear-Worm Gear Reducers - These reducers feature hard teeth helical gears and worm gears, with all gears made from 20CrMnTi material, carbonitrided for hardness up to 58-62HRC. After gear grinding, accuracy reaches 6th grade. Special attention is given to the worm gears, which are ground after precision carburizing to ensure a 75%+ contact area, guaranteeing product reliability and low noise. The main transmission parts use imported bearings, while sealing parts are Taiwan's frame oil seals. The power range is from 0.09KW to 55KW, with output torque from 60N.M to 10200N.M, and speed ratio from 15 to 390 (with 4-pole motor). Lower output speeds can be achieved with 6-pole or 8-pole motors. For even lower speeds, a two-stage reducer combination can be used, offering a multi-speed ratio (over 10,000). An infinitely variable speed drive can be added to the input end for further speed variation options. Available output types include vertical and horizontal, with self-locking functionality. Output shafts are available in solid and hollow designs (or custom made), allowing installation and use at various orientations and angles, and can be used for both forward and reverse rotation. Additionally, various motor types can be fitted, including standard, single-phase, explosion-proof, variable frequency, and brake motors. The S Series Helical Gear-Worm Gear Reducers are widely used in food and grain machinery, printing and packaging equipment, multi-level parking equipment, environmental protection machinery, conveying equipment, chemical equipment, metallurgical and mining equipment, and iron and steel power equipment.
