Abstract: The invention concerns a bearing arrangement (114), for a rotating component of a wind turbine (100), with two roller bearings. The rotating component is supported by the second roller bearings and a bearing housing (126). The roller bearings, the rotating component and the bearing housing (126) are arranged to form a pretension circuit (138). The first roller bearing (128) comprises a first bearing inner ring (140), a first bearing outer ring (142) and rolling elements (143). The first bearing outer ring (142) is axially moveable along the rotational axis (R) with respect to the bearing housing (126) and/or radially deformable with respect to the rotational axis (R). An adjustment device (144) is provided, which extends through a through-hole (158) of the bearing housing (126) and is accessible from outside (159) the bearing housing (126), wherein upon actuation the adjustment device (144) causes an axial movement and/or a radial deformation of the first bearing outer ring (142) to adjust the pretension of the bearing arrangement (114).

Abstract: The method is for operating a wind turbine (100) comprising at least one wind turbine component (1, 2, 3) and a setting system (31, 32) which is configured to execute at least two different measures for reducing the likelihood of overloading at least one wind turbine component. The method comprises a step in which first trigger information (Ia1) is provided, wherein the first trigger information is representative of whether the likelihood of overloading at least one wind turbine component exceeds a first threshold. If this is the case, a first output signal (OS1) is generated which is configured to cause the setting system to execute a first measure for reducing the likelihood of overloading at least one wind turbine component. In a further step, a second trigger information (Ia2) is provided which is representative of whether the likelihood of overloading at least one wind turbine component exceeds a second threshold after the first measure has been executed. If this is the case, a second output signal (OS2) is generated which is configured to cause the setting system to execute a second measure for reducing the likelihood of overloading at least one wind turbine component.

Abstract: The transportation system comprises a lower transport frame (22, 32) for a component for a wind turbine, an auxiliary element (23,33) placed horizontally next to the lower transport frame, an adapter element (10, 11) placed onto the pair of the lower transport frame and the auxiliary element and an upper transport frame (21, 31) for a component for a wind turbine. The upper transport frame is placed onto the adapter element so that the adapter element is arranged vertically between the upper transport frame and the pair of the lower transport frame and the auxiliary element. The adapter element comprises first connection means (1a, 1b) with the help of which it is connected to the upper transport frame, second connection means (2a, 2b) with the help of which it is connected to the lower transport frame and third connection means (3a, 3b) with the help of which it is connected to the auxiliary element. The adapter element distributes a load from the upper transport frame to the lower transport frame and to the auxiliary element so that the load is diverted downwards via the lower transport frame and the auxiliary element.
