With an annual production capacity of 50,000 pieces and a dedicated R&D team of 30 engineers, the company serves industries including wind power generation, mining machinery, metallurgical equipment, and large construction machinery. Export sales account for 30% of total revenue, with major markets in Asia, Europe, and North America.
Core Products and Technical Specifications
New Yinye's product portfolio includes the YL-series high precision gears (involute cylindrical internal/external gears, spur gears, spiral bevel gears), YL-series spiral bevel gears, and YL-series ring gears. Key parameters are summarized below:
| Product | Model | Material | Heat Treatment | Max Size | Precision (DIN) | Applications |
|---|---|---|---|---|---|---|
| High Precision Gears | YL-series | Low/medium-carbon alloy steel | Carburizing & quenching, induction quenching, nitriding | 200–2500 mm | Above DIN Class 4 | Wind power, aerospace, marine, machine tools, construction, mining, metallurgy, cement, port lifting |
| Spiral Bevel Gears | YL series | High-quality low/medium-carbon alloy steel | Carburizing & quenching | ≤1300 mm | Above DIN Class 5 | Mining, metallurgy/petrochemicals, wind power, marine, engineering machinery |
| Ring Gear (Big OD) | YL-Series | 42CrMo, 38CrMoAl | Nitriding, induction quenching | 800–2500 mm | DIN Class 7 (post-HT) | Wind power, metallurgy machinery |
Manufacturing & Quality Assurance Capabilities
New Yinye's maximum machining capacity reaches cylindrical gears up to 3000 mm outer diameter and spiral bevel gears up to 1250 mm. The company's equipment matrix includes German Hoefler RAPID/HELIX profile gear grinding machines, Liebherr LCS 1200, and Japanese O-M vertical turning/milling centers. Bevel gear processing is compatible with Klingelnberg, Gleason, and Oerlikon systems.
In-house heat treatment capabilities cover carburizing and quenching, high-frequency induction hardening, and nitriding. The company has mastered core technologies for deformation control of thin-walled parts after carburizing and bore/plane hardening.
Quality assurance is supported by specialized non-destructive testing (NDT) equipment: the German Fraunhofer non-destructive case depth/hardness tester and Barkhausen grinding burn detection system—a capability rarely found in standard gear factories. Coordinate measuring machines (CMM) include large Zeiss CMMs (3000×6000×2000 mm range), Hexagon CMMs, and Klingelnberg P152 & Gleason M&M professional gear inspection centers.
