    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: The present disclosure relates to wind turbines, pitch adjustment cylinders for adjusting a pitch angle of a blade of a wind turbine, to methods of assembling pitch adjustment cylinders, and to use of pitch adjustment cylinders in wind turbine, wherein the pitch adjustment cylinder comprises a cylinder barrel having an first cylinder barrel thread with a first thread pitch, a piston arranged movably in the cylinder barrel and extending out of the cylinder barrel for coupling to one of the blade and a hub of the wind turbine, a trunnion adapted to couple the cylinder barrel to the other one of the blade and the hub of the wind turbine, wherein the cylinder barrel extends through the trunnion, the trunnion has an first trunnion thread with a second thread pitch being different from the first thread pitch; and a sleeve arranged at least partially between the trunnion and the cylinder barrel, wherein the cylinder barrel extends through the sleeve, the sleeve has an inner sleeve thread with the first thread pitch and is engaged with the first cylinder barrel thread and the sleeve has an outer sleeve thread with the second thread pitch and is engaged with the first trunnion thread.
