A torque bracket arrangement for a wind power gearbox for transmitting a supporting force to a support structure of a wind power plant includes at least one radial support arm having an associated opening configured to receive a horizontal support pin. The at least one radial support arm is provided on a gearbox side and is configured to establish a detachable connection to at least one corresponding opening of a support eyelet unit arranged on the support structure. The at least one corresponding opening of the support eyelet unit includes an elastomer bearing bush into which the horizontal support pin is configured to be inserted. The elastomer bearing bush has differing rigidities depending on the load. The elastomer bearing bush consists of at least one soft region of low rigidity and at least one comparatively harder region of greater rigidity.

This invention relates to a wind turbine blade with retrofitted coating in and around areas where the blade is especially exposed to erosion damages, which is established by the coating including a glue layer, a fiber reinforced polymer layer and one or more non-reinforced polymer layers over the fiber reinforced layer, since the polymer layers stretch themselves out over the fiber reinforced layer and includes areas of the wind turbine blade's surface, which are less exposed to erosion damages. A method for creation of such a wind turbine blade and creation of such a coating and the coating itself, is also established with the invention.

A method for manufacturing a wind power plant rotor blade is provided. A mold for manufacturing at least a part of the wind power plant rotor blade is prepared. The mold has a recess, which is used to manufacture at least a part of the wind power plant rotor blade. Liquid erosion protection material is introduced into the recess. Fiber layers are placed in the recess of the mold after the liquid erosion protection material has at least partially hardened. A vacuum infusion bag or a vacuum infusion film is placed, and a vacuum infusion is performed with a resin, so as to obtain a composite component at least as part of the wind power plant rotor blade.

An integral ring gear and torque arm for a wind turbine gearbox and method of manufacturing same includes forming the ring gear and the associated gear housing as a single part using the same material, e.g., using a casting process. Further, the ring gear defines an inner circumferential surface having a plurality of gear teeth. Thus, the method also includes applying a coating material to the gear teeth of the ring gear via an additive manufacturing process, such as cold spraying, so as to increase a hardness of gear teeth.

Faired tethers with internal support structures providing support to strength cores, and systems therewith, are described. The faired tethers include one or more electrical conductors and one or more rigid supports that inhibit movement of a strength core within a faired tether.

A hub assembly for a wind turbine includes a hub having a surface defining a first set of bolt holes and a shaft having a flange having a second set of bolt holes. The first set of bolt holes is aligned with the second set of bolt holes at a hub-shaft interface. The hub assembly also includes a plurality of hub bolts extending through the first and second sets of bolt holes at the hub-shaft interface, a plurality of washers with one of the plurality of washers extending around each of the plurality of hub bolts, and at least one spacer positioned between the surface of the hub and a subset of the plurality of washers. At least two of the plurality of hub bolts extend through the at least one spacer.
