especially for these parts:
MaxiMuM
Yaw Ring
The yaw system of wind turbines is the component
responsible for the orientation of the wind turbine
rotor towards the wind. This is a mechanism that
rotates the nacelle to face the changing wind
direction. Made of alloy or bearing steel.
Planetary Ring Gear
Ring gears embrace the gearbox’s planetary
gears, allowing them to transform low
incoming speed to high outgoing speed.
