S Helical Worm Gear Reducer
S Helical Worm Gear Reducer
Description
S Series Helical–Worm Gear Reducer integrates a worm gear/worm pair with a precision helical gear stage, forming a highly efficient two-stage transmission where the input and output shafts intersect spatially. The gears and worm are carburized and quenched to a hardness of HRC 58–62, with a hardened layer depth of 0.2–2 mm for excellent wear resistance and long service life.
The worm wheel is cast from bronze using a centrifugal casting process to achieve superior strength and uniformity.
Featuring compact construction, stable torque output, and multi-installation flexibility, the S Series is widely used across demanding industrial sectors such as petroleum, metallurgy, mining, lifting, transportation, cement, construction, chemical processing, textiles, dyeing, pharmaceuticals, food processing, and environmental engineering.
Highlights
- High Reduction Ratios
Two-stage reduction (helical gear + worm gear) delivers smooth transmission with large ratio availability. - Innovative Structure
The combination of a worm gear/worm set and a helical gear creates a compact reducer with non-parallel, non-intersecting input and output shafts. - High Efficiency & Lightweight Design
Optimized tooth geometry, modular configuration, compact housing, and reduced weight ensure higher efficiency and appealing industrial aesthetics. - Low Noise & Low Vibration
Fine ratio grading and precision-machined gears significantly reduce vibration and operational noise.

FAQs
Does NUODUN support non-standard customization? What is the typical lead time?
Yes. NUODUN’s core competitiveness lies in the synergistic advantage of “customization + system integration.” We support structural customization, torque customization, input flange customization, mounting interface customization, stroke customization and more for products such as planetary gearboxes, screw jacks, electric cylinders, and gearboxes. The typical lead time for standard non-standard customization is 7–20 days, while more complex engineered projects are usually delivered within 3–6 weeks.
How does NUODUN ensure high precision and reliability in customized transmission systems?
Our engineering strength comes from long-term R&D investment, CAE simulation, lifetime calculation databases, modular design frameworks, and a mature testing/verification system. This ensures that every customized solution is not only manufacturable, but also reliable under real-world loads — balancing precision, durability, and cost efficiency.
Which industries commonly use NUODUN transmission components?
Our products are widely used in photovoltaic manufacturing, semiconductor equipment, automotive production, metallurgy, logistics, medical devices, aerospace, stage automation, and industrial automation — especially where precision positioning, heavy loads, or long service life are required.
How does NUODUN guarantee long-term product reliability?
All products undergo type testing, torque testing, vibration testing, life testing, noise measurement, and precision inspection. Core components such as gears, screws, and bearings are produced using advanced machining, grinding, heat treatment, and automated assembly processes.
Does NUODUN provide global after-sales support?
Yes. We offer remote technical support, installation guidance, troubleshooting, selection assistance, and long-term spare parts support for OEM/ODM partners.
