Abstract: A wind turbine (10) includes a first connecting structure (36) associated with the main shaft (34) fixed to a second connecting structure (40) of a rotor hub (22). A plurality of blades (24) is coupled to the rotor hub (22). A rotor locking disc (32) is carried on the main shaft (34). The rotor locking disc (32) has a peripheral region and a plurality of rotor locking elements (50) in the peripheral region for receiving one or more rotor locking pins (30). The first connecting structure (36) includes at least first and second sets of fastener holes (38a, 38b, 38b′). The first set of fastener holes (38a) is located at a position radially inward of the rotor locking elements (50) and the second set of fastener holes (38b, 38b′) is located between adjacent rotor locking elements (50). The first and/or second set of fastener holes (38a, 38b, 38b′) are used to receive fasteners (39a, 39b) to secure the main shaft (34) to the rotor hub (22).

Abstract: A rotor (1) for a wind turbine is disclosed. The rotor (1) comprises a hub (11) and at least one wind turbine blade (10), each wind turbine blade (10) being mounted on the hub (11) via a bearing unit (2). Each bearing unit (2) comprises a C-shaped bearing element (3) forming an inner ring and a T-shaped bearing element (4) forming an outer ring. The C-shaped bearing element (3) comprises a first bearing element part (12) and a second bearing element part (13). An interface (14) between the first bearing element part (12) and the second bearing element part (13) is positioned in such a manner that a third raceway pair (8) is formed between a protruding portion (5) of the T-shaped bearing element (4) and the first bearing element part (12) of the C-shaped bearing element (3) and the hub (11) or the wind turbine blade (10) is attached to the second bearing element part (13) of the C-shaped bearing element (3).

Abstract: Wind turbine pitch actuator mounting structure A mounting structure is described for attaching a pitch actuator to a hub of a wind turbine. The mounting structure has one or more legs each having a proximal end and a distal end, and a flexible intermediate portion between the proximal and distal ends. The mounting structure further comprises an actuator attachment portion for attaching to a wind turbine blade pitch actuator. The actuator attachment portion is arranged at the distal end(s) of the one or more legs. The proximal end(s) of the one or more legs are configured for attachment to a wind turbine hub. The flexible intermediate portion(s) of the one or more legs are configured to flex in use to absorb loads acting on the pitch actuator. The mounting structure therefore allows the pitch actuator to pivot in a first plane by virtue of the flexible legs. The pitch actuator may be attached to the mounting structure via pivot bearings arranged to allow the pitch actuator to pivot in a second plane, substantially perpendicular to the first plane.

Abstract: Pitch cylinders for adjusting a pitch angle of a blade, methods of assembling pitch cylinders, and the use of pitch cylinders in wind turbines are disclosed. The pitch cylinder includes a cylinder barrel having a first thread with a first pitch, a piston arranged in and extending out of the cylinder barrel for coupling to a blade or hub, and a trunnion to couple the cylinder barrel to the other of the blade or hub. The cylinder barrel extends through the trunnion. The trunnion has a first thread with a second pitch different from the first pitch, and a sleeve arranged between the trunnion and the cylinder barrel that extends through the sleeve. The sleeve has an inner sleeve thread with the first pitch engaged with the first cylinder barrel thread and an outer sleeve thread with the second pitch engaged with the first trunnion thread.
