Wind turbines must be aligned optimally to the wind in order to prevent extreme loads and to provide the highest possible energy output.
Azimuth drive/pitch drive
Wind turbines adjust automatically due to active systems. Geared motors and actuators convert the signals from the controller. Schaeffler Group Industrial offers bearing supports for slewing gears for nacelle and blade angle adjustment from one source:
In addition, the blade angle can be adjusted using electric or hydraulic systems. These use sealed plain bearings with the maintenance-free Elgoglide® fabric, protected against corrosion by means of the Corrotect® plating.
