Abstract: A power transmission device, comprising: a plurality of driving machines each of which has a pinion gear; a gear member which includes a damaged portion and engages with the plurality of pinion gears; and a controller which individually controls the plurality of driving machines. The driving machine is defined as being in a first state when disposed to engage with the gear member in a predetermined region including the damaged portion, and is defined as being in a second state when disposed to engage with the gear member in a region other than the predetermined region. The controller is configured to set torque to be generated by the driving machine of the first state to a low level, which is lower than the torque generated by the driving machine of the second state.

Abstract: The present invention relates to a wind turbine tower comprising a tower vibration damper (100) with a tuned mass damper and one or more impact damping units (113, 114, 115, 200, 300, 400). The tuned mass damper comprises a pendulum structure (101, 208), a chamber connecting a friction media (112) to the pendulum structure (101, 208) is at least partly immersed, and a suspension arrangement (103-111) suspending the pendulum structure (101, 208) inside the wind turbine tower such that the pendulum structure (101) is allowed to displace from a neutral position towards the outer boundary (102) of the chamber. The impact damping units (113, 114, 115, 200, 300, 400) are positioned between the pendulum structure (101, 208) and the outer boundary (102), such that the outer boundary (102) of the chamber and the pendulum structure (101, 208) may collide via the impact damping units (113, 114, 115, 200, 300, 400).

Abstract: A wind turbine blade includes: a blade body portion; and an anti-erosion layer disposed so as to cover a surface of the blade body portion partially. A center point of the anti-erosion layer in a circumferential length direction along a blade profile in a cross section orthogonal to a blade spanwise direction is shifted toward a pressure side from a leading edge of the blade body portion, at least in a part of an extension range of the anti-erosion layer in the blade spanwise direction.

Abstract: The present invention relates to an assembly of two structural parts of a wind turbine wherein the structural parts are to be connected in a flange-to-flange connection by a number of bolts and such that a flange of the first structural part and a flange of the second are centrally and rotationally aligned whereby a first borehole in the flange of the first structural part is matched and aligned with a corresponding first borehole in the flange of the second structural part. The structural parts may for example be a tower section or a foundation section. The assembly further comprises a first and a second rotational guide member releasably attached to each of the flanges of the structural parts. Each of the rotational guide members comprises a U-shaped or L-shaped structure of a first leg portion and a second leg portion connected by a central portion, the first leg portion ending in a positioning portion shaped to be inserted into a borehole of the flange, and the second leg portion comprising a stop member, and for at least one of the rotational guide members the structure comprised in the rotational guide member is U-shaped. The stop member of the first rotational guide member is configured for abutment to the second leg portion of the second rotational guide member when the flanges of the first and second structural parts are centrally and rotationally aligned. The invention further relates to a method of positioning and connecting two structural parts of a wind turbine as described above. The method includes first centrally aligning the structural parts with the flanges face-to-face and then rotating the structural part relative to each other until the rotational guide members come into contact with each other.

Abstract: The invention relates to a cooling panel assembly (2) for a wind turbine tower (1). It is arranged to be mounted on such a tower (1) on a section thereof as seen in the circumferential direction. The cooling panel assembly (2) includes at least one cooling panel (2a,2b). According to the invention, the cooling panel assembly (2) includes deflector means (6) mounted at the top of the at least one cooling panel (2a, 2b) such that the deflector means (6) shields the cooling panel assembly (2) from above. The deflector means (6) has substantially the same circumferential extension or more as the other parts of the cooling panel assembly (2). The invention also relates to a wind turbine tower (1) provided with at least one such cooling panel assembly (2).

Abstract: Wind Turbine Blade (12) Leading Edge (24, 30, 88) Protection Method In a first aspect of the invention there is provided a method of applying an erosion shield (22) to a leading edge region (30) of a wind turbine blade (12). The method comprises providing a wind turbine blade (12) comprising a blade shell (26) having an aerodynamic profile and defining a leading edge region (30); providing an erosion shield (22) made of a polymer material, the erosion shield (22) having an inner surface (36) to be bonded to the leading edge region (30) of the blade shell (26), and an outer surface (38, 84, 98) to be exposed in use; activating (44) the inner surface (36) of the erosion shield (22), and cleaning (42) the inner surface (36) of the erosion shield (22) using a solvent. The method further comprises applying a layer of wet adhesive (66, 68, 72A) to the inner surface (36) of the erosion shield (22); applying a layer of wet adhesive (66, 68, 72A) to the leading edge region (30) of the blade shell (26); arranging the erosion shield (22) against the leading edge region (30) of the blade shell (26) such that wet-to-wet adhesive (66, 68, 72A, 72, 96) contact is established between the inner surface (36) of the erosion shield (22) and the blade shell (26), and curing the adhesive (66, 68, 72A, 72, 96) to bond the erosion shield (22) to the leading edge region (30) of the blade shell (26).
