Wind Turbine Yaw drive and Brake Assembly
Once the yaw ring is installed, the nacelle main frame must be turned over in order to complete the yaw system assembly. Temporary legs are installed, and fixtures are added to the yaw ring. The main frame is lifted, and one side is let down while the frame is rotated. Here you can see the…

Wind Turbine Main Shaft Brake: Frictional forces
While the rotation of the rotor of the wind turbine can be slowed by changing the pitch angle of the blades during aerodynamic braking, the rotor needs a mechanical main shaft brake to keep it stopped completely. Frictional force is an essential physics concept that will help explain the working mechanism of the main shaft…
