Video: Wind Turbine Yaw System Introduction The wind turbine yaw control system provides two functions that are crucial to safe and efficient operation: The nacelle must point directly into the wind for maximum efficiency. Also, a rotor disk that is not perpendicular to the relative wind experiences higher loading on the portion of the disk…
The main parts of the yaw brake hydraulic system and their functions are Accumulator: The accumulator stores fluid under pressure, and serves as a backup source of clamping pressure if system pressure is lost. Bleed Valve: Used to drain fluid from the accumulator to relieve pressure during service operations. Brake Calipers: Pressure in the brake…
Three different types of forces act on gears and bearings in a gearbox. They are gravitational forces, frictional forces, and contact forces. The most significant are contact forces, due to the magnitude of the contact stresses that these forces are generating on the surfaces of the moving parts during operation. Contact force occurs when the…
