As the world accelerates its shift toward sustainable energy, wind power continues to gain momentum as a clean and efficient energy source. The increasing size and performance demands of wind turbines have placed higher expectations on the mechanical properties of core components.
Forged steel parts have become vital in ensuring the safety, durability, and reliability of wind turbine systems, particularly for offshore installations and high-altitude wind farms exposed to extreme conditions.
Core Forged Components Used in Wind Turbines
Forgings are widely used throughout a wind turbine’s drivetrain and support structure. Below are some of the most critical forged parts and their applications:
Main Shaft Forgings
These large components connect the rotor hub to the gearbox and must endure high levels of torsional and bending stress. A forged, one-piece shaft structure enhances fatigue resistance and long-term operational safety.
Gear Shafts and Transmission Elements
Forged from alloy steels such as 42CrMo4 or 18CrNiMo7-6, these parts require precise heat treatment and surface hardness for optimal performance under dynamic load.
Yaw and Pitch Bearing Rings
Forged rings ensure that the turbine rotor can rotate into the wind and adjust blade angles in real time. Their structural integrity is essential to the overall efficiency of the system.
Tower Flanges
These flanges are forged to join tower sections and must offer excellent weldability and dimensional precision for secure assembly.
Why Forgings Are the Preferred Choice in Wind Energy
Superior Structural Properties
Forgings provide a dense, uniform grain structure with better strength than cast or welded parts.
Outstanding Fatigue Resistance
As turbines operate under cyclical loads for long periods, forged parts offer significantly improved fatigue life.
Wide Material Options
We support custom forging using materials such as 42CrMo, 20CrNi2Mo, and 18CrNiMo7- 6 to match your technical requirements.
Excellent Performance in Harsh Environments
Especially in offshore applications, forged parts can be treated to enhance corrosion resistance and withstand salt spray and moisture.
