Abstract
A wind turbine, including a hub, a blade, a blade bearing which is connected to the hub and which enables a rotational movement of the blade relative to the hub, and an adjustment device for adjusting a pitch angle of the blade, wherein the adjustment device includes at least one actuator and wherein an effective direction of an adjustment force of the at least one actuator when adjusting the pitch angle of the blade is tilted in an angle relative to a bearing plane of the blade bearing. One advantage of the wind turbine is that the adjustment force for adjusting the pitch angle is transmitted directly into the blade bearing or the bearing plane. Further, an offset of the attacking point of the adjustment force can be reduced or completely avoided.
