ed m an er u rm ne m o gi i erf En ax g P M Lin IL DR Drilling is one of the major machining operations in wind turbine manufacturing, especially for these parts: r fo ce Planetary Ring Gear 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. Yaw Ring Ring gears embrace the gearbox’s planetary gears, allowing them to transform low incoming speed to high outgoing speed. ST E U Q ON RE to 12xD p Drill u 2 Guide Pads GP-03 Tower Flange Blade Bearing Adjusts the angle of the blades by rotating a bearing at the root of each blade. The blade bearing enables to control power and slow the rotor. Made of bearing steel. The vast majority of commercial wind turbines use tubular steel towers. Tower heights depend on rotor diameter and wind speed conditions of the site. Their heights range from 50 meters for a 1 MW turbine to as high as 125 meters and more for very large turbines. The flange comprises a large scale of rolled steel which connects the tower’s conical links.
