Definitions

  • the invention relates to a blade connection for the rotor blades of a wind turbine, in which the rotor blades or the hub are provided with at least one insert made of a solid material which is inserted into the root of the rotor blade or blades made of a fiber composite material and made of a plurality of laminate layers placed on top of one another or the hub is inserted and which is connected to the hub or the rotor blade of the wind turbine via bolts screwed into threaded bores in the inserts.
  • the energy generated by a wind turbine is based on the conversion of the translational air movement energy into rotary energy, which takes place via rotor blades.
  • the rotor blades of the wind turbine are connected to a rotor hub at their root end, either directly or via a blade bearing arranged between the rotor blade and the rotor hub.
  • the rotor hub and rotor blades together form the rotor.
  • the invention has for its object to provide a blade connection that allows transmission of high tensile and compressive forces.
  • this object is achieved in that the at least one insert is conical in cross section, the peripheral surface of the at least one insert with a A plurality of elevations and / or recesses is provided, the laminate layers extending parallel to the insert are formed in the region of the insert with a profile complementary to the profile of the at least one insert and the laminate layers are sewn together in the region of the insert perpendicular to their extension.
  • the insert can be designed in the form of a ring, but it is also possible to provide two half-ring-shaped inserts or a plurality of ring-segment-shaped inserts designed as ring-part-shaped with radial side walls
  • the method according to the invention for producing the blade connection of a wind power installation is characterized by sewing the still impregnated, superimposed fiber fabrics in the area of the at least one insert perpendicular to their extension, inserting the at least one insert into the space left free by the sewn fiber fabrics and Infuse or inject a resin into the scrim to form the laminate layers.
  • FIG 1 shows an insert in cross section, this on one side showing the structure of the sewn laminate layers (not shown on the other side),
  • Fig. 2 shows a first detailed view from Fig. 1 and
  • FIG. 3 shows a second detailed illustration from FIG. 1.
  • the basic structure of the insert 1, which is preferably metallic, is conical. Its peripheral surface is provided with a plurality of elevations and recesses 2.
  • the insert 1 is embedded in a laminate structure 3 provided from a fiber plastic composite.
  • This laminate structure is provided with different seams in the area of the insert 1, namely with an assembly and positioning seam 4, which allows improved force guidance in the laminate structure 3.
  • An ILS seam increases the interlaminar shear strength of the laminate layers.
  • a final assembly seam 6 serves to protect against Delaminations of the fiber plastic composite in the area of the internal thread 7, which is introduced in the center of the insert 1.
  • An additionally introduced fiber reinforcement material 8 forms the positive connection with the elevations and recesses 2 in the laminate structure.
  • the insert 1 can be designed as a full ring with an inwardly tapering cross-section, but it is also possible to make it semi-ring-shaped or to provide a plurality of ring segment-shaped inserts.
  • a third possibility is to provide a large number of individual inserts which are inserted into the preformed profile of the preform of the rotor blade or the hub and then produce the positive connection by injecting or infusing the resin.
  • the conical design of the inserts makes it easier to insert them into the non-impregnated but already sewn fiber fabrics, and on the other hand it prevents force jumps between the insert and the laminate.

Abstract

L'invention concerne un raccord de pale placé entre les pales de rotor et le moyeu d'une éolienne. Dans ledit raccord, les pales de rotor et/ou le moyeu sont pourvus d'au moins un insert constitué d'un matériau résistant, qui est introduit dans la racine de la pale de rotor et dans la bride du moyeu de la pale de rotor, laquelle est constituée de plusieurs couches liées d'un stratifié, et qui est relié au moyeu et à la pale de rotor de l' éolienne par des boulons qui sont vissés dans des alésages filetés dudit insert. Selon l'invention: l'insert ou les inserts présente(nt) une section transversale conique; la surface périphérique de l'insert ou des inserts est pourvue d'une pluralité d'élévations et/ou de cavités; les couches de stratifié qui s'étendent parallèlement à l'insert présentent, à proximité de l'insert, un profil qui est complémentaire de celui de l'insert ou des inserts; et les ensembles de fibres se trouvant dans la zone de l'insert sont cousus ensemble perpendiculairement à leur longueur. L'invention concerne également un procédé de réalisation d'un tel raccord.
