All gear materials are made of 20CrMnTi, treated with carburization, achieving a surface hardness of 58-62HRC. After gear grinding, the precision can reach 6 levels. Specifically, the worm gears are ground after precision carburization to ensure a contact area of over 75%, guaranteeing product reliability and low noise. The reducer features imported bearings in all major transmission parts, with sealing rings using Taiwanese frame oil seals. The power range is from 0.09KW to 55KW, with output torque from 60N.M to 10200N.M. The speed ratio can be from 15 to 390 (with a 4-pole motor), and lower output speeds can be achieved with 6 or 8-pole motors. For even lower output speeds, a two-stage reducer combination can be used, offering a lower speed ratio (over 10,000). An infinitely variable speed drive can be added to the input end for further speed variation. Output types include vertical and horizontal, with self-locking capabilities. Output shafts are available in solid, hollow (or custom), and can be installed in various orientations and angles, allowing for forward and reverse operation. Additionally, various types of motors can be paired, including standard, single-phase, explosion-proof, variable-frequency, and brake motors. The S series helical worm gear-reducer is widely used in food and grain machinery, printing and packaging equipment, multi-story parking equipment, environmental protection machinery, conveying equipment, chemical equipment, metallurgical and mining equipment, and steel and power equipment.
