Brief: In this walkthrough, we highlight key design ideas and how they translate to performance. You'll see a detailed demonstration of high-precision forged gears engineered for wind turbine main gearbox drive systems. The video showcases the manufacturing process from controlled forging to precision machining, explaining how these components deliver exceptional strength, fatigue resistance, and reliability under continuous high-torque operation in demanding wind energy applications.
Related Product Features:
  • Forged with a high forging ratio (≥4.0) for uniform grain flow, improved toughness, and superior fatigue life in high-load wind turbine environments.
  • Precision machined gear profiles via CNC hobbing, shaping, and grinding to guarantee tight tolerances and low noise levels for efficient gearbox performance.
  • Optimized heat treatment through carburizing, quenching, and tempering enhances surface hardness while maintaining a tough, shock-resistant core.
  • Manufactured from premium alloy steels like 18CrNiMo7-6, 20CrMnMo, and 42CrMo4 for superior wear resistance and dimensional stability under fluctuating wind loads.
  • Designed to withstand long-term exposure to high torque, vibration, and fluctuating wind loads in both onshore and offshore wind turbine applications.
  • Conforms to IEC wind turbine gearbox standards and AGMA gear accuracy classifications, ensuring reliability and performance compliance.
  • Available as rough-machined blanks or fully finished precision-ground gears, with optional anti-corrosion coating for offshore storage and transportation.
  • Rigorous testing and inspection including chemical analysis, mechanical properties testing, and non-destructive testing (UT, MT) for quality assurance.
Faqs:
  • What materials are used in these high-precision forged gears for wind turbines?
    Our gears are manufactured from premium alloy steels including 18CrNiMo7-6, 20CrMnMo, and 42CrMo4, chosen specifically for their superior wear resistance, hardenability, and dimensional stability under the fluctuating wind loads encountered in wind turbine applications.
  • How does the forging process contribute to the gear's performance in wind turbine gearboxes?
    The gears are processed through controlled forging with a forging ratio of ≥4.0, which ensures uniform grain flow, refined grain structure, and improved impact resistance. This results in exceptional mechanical strength and outstanding fatigue life necessary for high-load wind turbine environments.
  • What testing and inspection procedures are performed on these gears?
    Each gear undergoes comprehensive testing including chemical composition analysis, mechanical properties testing (yield strength, tensile strength, impact toughness, hardness profile), non-destructive testing (UT, MT, surface flaw detection), and gear accuracy measurement (tooth profile, lead, contact pattern, backlash) to ensure compliance with AGMA/ISO standards.
  • Are these gears suitable for both onshore and offshore wind turbine applications?
    Yes, these high-precision forged gears are engineered for both onshore and offshore wind turbine applications. They are designed to withstand harsh conditions including high torque, vibration, and fluctuating wind loads, with optional anti-corrosion coating available specifically for offshore storage and transportation requirements.
