The main frame(nacelle front frame) is the core supporting structure of a wind turbine nacelle, with its primary functions including:
1. System Support – Secures the hub and blades, bearing their gravitational, centrifugal, and wind pressure loads to ensure stable rotation of the blade system.
2. Load Transmission – Efficiently transfers torque and axial forces generated by the blades to the main shaft, generator, and tower, driving power generation.
3. Structural Integrity – Maintains precise alignment between the blades and main shaft, suppresses vibrations, and protects critical components such as the gearbox from dynamic load impacts.
