Abstract
Yaw brakes for wind turbines are proposed, the wind turbines having a tower, a nacelle and a yaw system for rotating the nacelle with respect to the tower. The yaw brakes comprise a locking part, having a toothed profile at a side facing a toothed profile of an annular gear of the yaw system. The locking part of the yaw brakes is movable in a radial direction relative to the annular gear, between a brake position and a non-brake position. Brake discs and callipers may be eliminated.
