The helical tooth flank design of helical gears ensures a gradual and smooth engagement process.

　　The helical tooth profile of helical gears ensures a gradual and smooth engagement, reducing impact and noise and enhancing transmission smoothness.

　　Through the continuous meshing of multi-stage gears, the high-speed rotation of the input shaft is converted into low-speed, high-torque rotation at the output shaft, thereby meeting the requirements under various load conditions.

　　Strong Load-Carrying Capacity: The reducer is manufactured using high-quality materials and precision machining, offering superior load-bearing capacity and overload protection to ensure stable equipment operation.

　　Highly adaptable: This product series offers a full range of specifications, a wide speed range, and excellent versatility, accommodating various installation methods while delivering safe, reliable performance and long service life.

　　Excellent heat dissipation: The textured surface design enhances heat dissipation, helping to lower operating temperatures and extend the equipment’s service life.

　　Self-locking feature: The worm gear drive exhibits self-locking characteristics, making it particularly well-suited for applications involving frequent starts. It can be coupled with various types of gear reducers and driven by a wide range of motor types.

　　Helical gear section: When power is applied to the input shaft, it first passes through a helical gear for the initial stage of speed reduction. Compared with spur gears, helical gears have a higher contact ratio, delivering smoother transmission; moreover, their design helps reduce noise and enhance load-carrying capacity.

　　Worm and worm gear assembly: After being reduced by a helical gear, the power is transmitted to the worm. The worm meshes with the worm wheel, achieving the second stage of speed reduction. The worm is typically a helical gear, while the worm wheel is the gear that meshes with it. As the worm rotates, it drives the worm wheel to turn; because the worm wheel has significantly more teeth than the worm, this stage can achieve a substantial reduction ratio.

　　Output section: After two-stage reduction, the power is ultimately transmitted to the working machine via the output shaft. Thanks to the self-locking characteristics of the worm and worm gear, the S-series helical‑worm gear reducer also features a certain degree of self‑locking, meaning it will not reverse under load due to gravity.

　　Features

　　High gear ratio: By combining helical gears with worm and worm wheel pairs, a large gear ratio can be achieved, meeting the requirements of various application scenarios.

　　High efficiency: Helical gears offer high transmission efficiency, and the meshing configuration of worm gears further enhances the overall efficiency of the reducer.

　　Low Noise: The helical gear design reduces noise levels, resulting in quieter operation of the reducer.

　　Self-locking feature: The self-locking property of worm gears provides convenience for applications that require prevention of reverse rotation.

　　Compact Design: The S-series helical‑worm gear reducers feature a compact design that saves space and facilitates installation and maintenance.

　　Power range: Typically spans from 0.12 kW to 22 kW, catering to diverse load requirements.

　　Torque range: from 10 N·m to 4,890 N·m, ensuring robust torque output.

　　Output speed: Adjustable according to the specific model, with a range from 0.12 r/min to 397 r/min.

　　Structural configurations: These include S‑shaft‑extension coupling, SA‑shaft‑mounted coupling, SF‑shaft‑extension flange mounting, SAF‑shaft‑mounted flange mounting, and other variants, designed to accommodate diverse installation environments and application requirements.

　　S-series helical‑worm gear reducers are widely used in industries such as metallurgy, mining, lifting, transportation, construction, chemical processing, textiles, printing and dyeing, pharmaceuticals, food processing, rubber, plastics, and papermaking, as well as within the reducer industry itself. In these sectors, they drive a variety of machinery and equipment, including mixers, conveyors, cranes, winches, presses, crushers, dough kneaders, brick‑and‑tile machines, and more.
