On June 6, 2025, Wuxi Jiuyixin Transmission Equipment Co., Ltd., a leading domestic transmission equipment manufacturer, officially announced the launch of its upgraded W series (20-40 teeth) and G series (30-36 teeth) herringbone gear pulley standard components. Leveraging innovative design, exceptional performance, and broad applicability, these two series underscore the company's R&D prowess in high-end transmission technology, offering new solutions for efficient and stable industrial equipment operation.

I. Technological Breakthrough: Herringbone Gear Structure Drives Efficient Transmission

Both the W and G series herringbone gear pulleys feature a bidirectional helical tooth design, forming a symmetrical "herringbone" structure through tilted tooth surfaces. This design automatically offsets axial thrust, significantly reducing vibration and noise during transmission. For instance, the W series achieves over 98% transmission efficiency, a 15% improvement over traditional spur gear pulleys. The G series optimizes tooth contact ratio for more uniform load distribution, enhancing tooth surface contact by 30% and extending service life to 1.5 times that of conventional products.

Core Advantages：
Axial Force Self-Balancing: The bidirectional helical tooth structure eliminates additional bearing loads, reducing wear and extending equipment lifespan.
Low Noise, High Efficiency: Symmetrical tooth engagement minimizes impact noise, with sound levels 10-15 dB lower than spur gear pulleys.
High Load Capacity: The W series, covering 20-40 teeth, boosts torque capacity by 25%, while the G series combines compactness with power density in its 30-36 tooth design.

II. Versatile Applications: From Heavy Industry to Precision Manufacturing

Built on a modular design philosophy, the W and G series cater to diverse industrial scenarios:
W Series (20-40 Teeth):
Applications: High-load environments such as metallurgical rolling, mining machinery, marine propulsion, and wind turbine gearboxes.
Case Study: In large-scale rolling mill systems, W series pulleys ensure precise torque distribution in hot rolling processes via rigid motor-to-roll connections, reducing failure rates by 30%.
Technical Specifications: Supports module ranges of 3-8 mm, tooth surface hardness of 58-62 HRC, and line speeds up to 80 m/s.
G Series (30-36 Teeth):
Applications: Precision transmission in printing machinery, packaging equipment, textile machinery, and robotic joints.
Case Study: In collaborative robot joint modules, G series pulleys achieve micron-level precision with repeatable positioning errors ≤0.01 mm and NVH performance improved by 40%.
Technical Specifications: Lightweight aluminum alloy construction reduces inertia by 20%, supporting vertical installation and bidirectional transmission.

III. Manufacturing Upgrade: 5-Axis CNC Milling Ensures Quality

To meet high-end manufacturing demands, Jiuyixin has adopted 5-axis CNC milling technology for single-setup machining of herringbone gear pulleys. This process surpasses traditional hobbing limitations, efficiently handling hardened steel, titanium alloys, and other challenging materials with tooth surface roughness ≤0.8 μm. For high-speed rail gearboxes, optimized herringbone tooth fillet designs reduce stress concentration by 30%, significantly enhancing fatigue life.
