New Yinye Transmission touts DIN Class 4-5 gear precision

Jiangsu New Yinye Transmission Electromechanical says it has developed custom ultra high precision gears with wear-resistant heat treatment processes for wind power, mining and machine tool applications. The company says its capabilities aim to meet rising demand for large, durable transmission components as global gear and precision gearbox markets expand.

Why it matters: - Jiangsu New Yinye Transmission says its custom gears are built for applications where transmission accuracy, wear resistance and long service life directly affect uptime and maintenance costs. - The company’s DIN Class 4 to 5 precision target and Ra 0.4 surface roughness place its products in demanding industrial segments, including wind power, mining machinery, metallurgical equipment and precision machine tools. - New Yinye Transmission also links its gear production to growing demand in the global gear market and the precision gearbox and geared motor segment.

What happened: - New Yinye Transmission said it has developed core technologies that support custom ultra high precision gears meeting DIN 3962/3965 Class 4 to 5 standards. - The company was founded in 1993 and is identified as a National “Little Giant” High-Tech Enterprise. - New Yinye Transmission operates a 25,308-square-meter facility, employs about 120 staff and includes a 30-person R&D team. - The company says annual production capacity reaches 50,000 pieces, and export sales account for 30% of total revenue. - Major export markets include Asia, Europe and North America.

The details: - New Yinye Transmission specializes in R&D, manufacturing and heat treatment for high-precision cylindrical gears and spiral bevel gears. - The company uses German Hoefler RAPID/HELIX profile gear grinding machines and Liebherr LCS 1200 equipment for five-axis grinding optimization. - The grinding process controls tooth profile, lead and pitch deviations at the same time. - New Yinye Transmission processes cylindrical gears up to 3,000 mm outer diameter and spiral bevel gears up to 1,250 mm. - The company uses high-strength materials such as 18CrNiMo7-6 for wind power gears designed for high-fatigue resistance, stable operation and long service life in multi-megawatt turbines. - The facility is compatible with Klingelnberg, Gleason and Oerlikon bevel gear systems for custom tooth contact patterns. - New Yinye Transmission says the process can certify above DIN Class 4 for cylindrical gears and above DIN Class 5 for spiral bevel gears. - For heavy-load applications, the company uses carburizing and quenching for steels including 17CrNiMo6, 18CrNiMo7-6 and 20CrNi2Mo. - The company also performs nitriding and high-frequency induction hardening for 42CrMoA and 38CrMoAl. - New Yinye Transmission says it controls deformation in thin-walled parts after carburizing and combines bore and plane hardening to preserve dimensional stability. - Post-treatment hardness typically exceeds 58 HRC. - Quality checks include a German Fraunhofer case depth/hardness tester and a Barkhausen grinding burn detection system. - For low-noise, low-backlash applications, the company designs involute cylindrical internal and external gears and spiral bevel gears with optimized backlash. - These gears are aimed at machine tools, canning machinery and biofuel processing equipment that run at high speed and continuously. - The YL-Series high precision gear line includes involute cylindrical internal and external gears, spur gears and spiral bevel gears. - The YL-Series machining range runs from 200 mm to 2,500 mm, with machining accuracy above DIN Class 4. - The maximum machining capacity includes cylindrical gears up to 3,000 mm OD and spiral bevel gears up to 1,250 mm. - Inspection equipment includes Zeiss CMM, Hexagon CMM, Klingelnberg P152 and Gleason M&M gear inspection centers. - The YL Series spiral bevel gears have a maximum dimension of 1,300 mm and accuracy above DIN Class 5. - The YL-Series ring gear line covers 800 mm to 2,500 mm OD, with DIN Class 7 accuracy after heat treatment. - The ring gear line uses 42CrMo and 38CrMoAl and is designed for high toughness, wear resistance, anti-deformation and stable operation accuracy.

Between the lines: - The emphasis on precision grinding, heat treatment control and non-destructive testing suggests New Yinye Transmission is positioning itself as a supplier for applications where failure costs are high. - The company’s focus on multi-megawatt wind turbines, marine systems and machine tools points to a strategy centered on specialized, high-spec industrial markets rather than commodity gear production. - Market references in the release suggest management sees growth tied to electrification, industrial automation and larger renewable-energy drivetrain systems.

What's next: - New Yinye Transmission is likely to pursue more business in wind power, mining, marine, machine tool and robotics markets as demand for high-precision gearing increases. - The company invites inquiries from buyers seeking custom ultra high precision gears and lists Jane Huang as a contact at jane@wxyinye.com or +86 15052211619. - The company’s website is More information.

The bottom line: - New Yinye Transmission is betting that tighter tolerances, stronger heat treatment and lower backlash will win work in industrial sectors that need durable gears built to exacting standards.
