グ機構。 The wind turbine blade is divided into a tip blade on the blade tip side and a root, and the tip blade is held in a shank on the root side arranged in the direction of the pitch axis, and is held rotatably by pressing the tip blade toward the root side with a spring in the axial direction. The variable tip blade structure uses a cylindrical cam and a pin to convert the rotation into the feathering direction.The tip blade can be freely rotated using a thrust ball bearing that also functions as a rotational torque limiter by providing a recess into which the ball fits into the centering bearing ring. A tip feathering mechanism for wind turbine blades that is characterized by the following.
