Description
Die Erfindung betrifft einen Blattanschluss für die Rotorblätter einer Windenergieanla ge, bei der die Rotorblätter bzw. die Nabe mit wenigstens einem Insert aus einem festen Material versehen sind, das in die Wurzel des bzw. der aus einem Faserverbundwerk stoff gefertigten, aus mehreren aufeinander gelegten Laminatschichten gefertigten Ro torblatts bzw. der Nabe eingesetzt ist und das mit der Nabe bzw. dem Rotorblatt der Windenergieanlage über Bolzen verbunden ist, die in Innengewindebohrungen in dem Insert eingeschraubt sind. The invention relates to a blade connection for the rotor blades of a wind turbine ge, in which the rotor blades or the hub with at least one insert from a fixed Material is provided, which in the root of or from a fiber composite Ro made of fabric, made of several layers of laminate Torblatts or the hub is used and that with the hub or the rotor blade of the Wind turbine is connected via bolts that are in internal threaded holes in the Insert are screwed in.
Die Energieerzeugung durch eine Windenergieanlage beruht auf der Wandlung der translatorischen Luftbewegungsenergie in rotatorische Energie, die über Rotorblätter erfolgt. Die Rotorblätter der Windenergieanlage sind an ihrem Wurzelende mit einer Rotornabe verbunden, und zwar wahlweise direkt oder über ein zwischen Rotorblatt und Rotornabe angeordnetes Blattlager. Rotornabe und Rotorblätter bilden gemeinsam den Rotor.The generation of energy by a wind turbine is based on the change of translational air motion energy into rotational energy via rotor blades he follows. The rotor blades of the wind turbine are with one at their root end Rotor hub connected, either directly or via a between the rotor blade and rotor hub arranged blade bearing. The rotor hub and rotor blades form together the rotor.
Bei dieser Wandlung der translatorischen Luftbewegungsenergie in Rotationsenergie entstehen an der Verbindung zwischen dem Rotorblatt und der Rotornabe, dem soge nannten Blattanschluss, große statische und dynamische Biegemomente, die damit ver bundenen Zug- und Druckkräfte müssen von dem Blattanschluss übertragen werden.With this conversion of the translational air kinetic energy into rotational energy arise at the connection between the rotor blade and the rotor hub, the so-called called sheet connection, large static and dynamic bending moments, which ver bound tensile and compressive forces must be transmitted from the blade connection.
Es ist bereits bekannt, in den Laminataufbau der Blattwurzel Inserts einzukleben, die aus einem Metall oder aber einem anderen festen Material gefertigt sind. Dabei stellt sich das Problem, dass bei derart eingeklebten Inserts die Kräfte nur über die Verkle bungsfläche übertragen werden, die Oberfläche der Inserts muss daher groß dimensio niert sein.It is already known to glue inserts into the laminate structure of the leaf root are made of a metal or another solid material. It poses the problem is that with inserts glued in in this way, the forces can only be exercise surface, the surface of the inserts must therefore be large be kidneyed.
Ein Rotorblatt für Windkraftanlagen aus faserverstärkten Kunststoffen ist aus der DE 43 35 221 C1 bekannt. Die DE 195 29 476 schlägt einen Flügel aus Faserverbund werkstoffen für Luftfahrzeuge vor. Die DE 198 34 772 A1 offenbart ein Faserverbund bauteil, das ein Insert mit einem mit einem Innengewinde versehenen Bolzen aufweist.A rotor blade for wind turbines made of fiber-reinforced plastics is from DE 43 35 221 C1 known. DE 195 29 476 proposes a wing made of fiber composite materials for aircraft. DE 198 34 772 A1 discloses a fiber composite component that has an insert with an internally threaded bolt.
Der Erfindung liegt die Aufgabe zugrunde, einen Blattanschluss zu schaffen, der eine Übertragung auch hoher Zug- und Druckkräfte erlaubt.The invention has for its object to provide a sheet connection, the one Transmission of high tensile and compressive forces allowed.

Die Erfindung wird im Folgenden anhand einer Zeichnung erläutert. Dabei zeigt:The invention is explained below with reference to a drawing. It shows:
Fig. 1 ein Insert im Querschnitt, wobei dieses auf der einen Seite den (auf der anderen Seite nicht dargestellten) Aufbau der vernähten Laminatschichten wiedergibt, Fig. 1 shows an insert in cross-section, this on the one hand represents the structure of the stitched laminated layers (not shown on the other side),
Fig. 2 eine erste Detaildarstellung aus Fig. 1 und Fig. 2 shows a first detailed view from Fig. 1 and
Fig. 3 eine zweite Detaildarstellung aus Fig. 1. Fig. 3 is a second detail view in FIG. 1.
Das - vorzugsweise metallische - Insert 1 ist in seiner Grundstruktur konisch. Seine Umfangsfläche ist mit einer Mehrzahl von Erhöhungen und Aussparungen 2 versehen. Das Insert 1 ist in einen aus einem Faserkunststoffverbund bestehenden Laminataufbau 3 eingebettet. Dieser Laminataufbau ist im Bereich des Inserts 1 mit unterschiedlichen Nähten versehen, nämlich mit einer Montage- und Positionierungsnaht 4, die eine ver besserte Kraftanleitung in den Laminataufbau 3 erlaubt. Eine ILS-Naht erhöht die inter laminare Scherfestigkeit der Laminatschichten. Eine Endmontagenaht 6 dient zum Schutz vor Delaminationen des Faserkunststoffverbundes im Bereich des Innengewin des 7, das mittig in das Insert 1 eingebracht ist.The - preferably metallic - insert 1 is conical in its basic structure. Its peripheral surface is provided with a plurality of elevations and recesses 2 . The insert 1 is embedded in a laminate structure 3 consisting of a fiber plastic composite. This laminate structure is provided in the area of the insert 1 with different seams, namely with an assembly and positioning seam 4 , which allows improved strength guidance in the laminate structure 3 . An ILS seam increases the inter-laminar shear strength of the laminate layers. A final assembly seam 6 serves to protect against delamination of the fiber-plastic composite in the area of the internal thread of the 7 , which is inserted in the center of the insert 1 .
Ein zusätzlich eingebrachtes Faserverstärkungsmaterial 8 bildet den Formschluß mit den Erhöhungen und Aussparungen 2 in dem Laminataufbau.An additionally introduced fiber reinforcement material 8 forms the positive connection with the elevations and recesses 2 in the laminate structure.
Das Insert 1 kann als Vollring mit sich nach innen verjüngendem Querschnitt ausgebil det sein, es ist jedoch auch möglich, diesen halbringförmig auszubilden oder aber eine Vielzahl von ringsegmentförmigen Inserts vorzusehen.The insert 1 can be ausgebil det as a full ring with an inwardly tapering cross-section, but it is also possible to form this semi-ring-shaped or to provide a plurality of ring segment-shaped inserts.
Es ist möglich, einen noch unge tränkten Vorformling zunächst unter geeignetem Vernähen der Fasergelege zu fertigen, das Insert einzusetzen und sodann das Harz zu infundieren oder zu injizieren, wodurch der Formschluß zwischen den Laminatschichten und dem Profil des Inserts hergestellt wird.It is possible to have an unexperienced to produce the soaked preform with suitable stitching of the fiber fabric, insert the insert and then infuse or inject the resin, thereby the positive connection between the laminate layers and the profile of the insert becomes.
Es ist jedoch auch möglich, in - an sich bekannter Weise - die Hälften des Rotorblattes in einer Halbschale herzustellen, die Laminatschichten der Blattwurzel mit einem im Bereich des Inserts diesem komplementär entsprechenden Profil auszugestalten, das halbringförmige Insert sodann einzusetzen und anschließend die beiden Hälften des Rotorblatts aufeinander zu legen.However, it is also possible, in a manner known per se, for the halves of the rotor blade in a half shell, the laminate layers of the leaf root with an in Area of the insert to complement this complementary profile, the then insert half-ring-shaped insert and then the two halves of the Put the rotor blades on top of each other.
Eine dritte Möglichkeit besteht darin, eine Vielzahl von einzelnen Inserts vorzusehen, die in das vorgeformte Profil des Vorformlings des Rotorblatts bzw. der Nabe eingesetzt werden und den Formschluß sodann durch Injizieren oder Infundieren des Harzes her zustellen.A third possibility is to provide a large number of individual inserts, inserted into the preformed profile of the preform of the rotor blade or the hub and the positive connection then by injecting or infusing the resin to deliver.
Die konische Ausbildung der Inserts erleichtert zum einen das Einbringen in die noch ungetränkten, aber bereits miteinander vernähten Fasergelege, es bewirkt zum anderen, dass Kraftsprünge zwischen dem Insert und dem Laminat vermieden werden.On the one hand, the conical design of the inserts makes it easier to insert them into the unimpregnated but already sewn fiber fabric, on the other hand it causes that force jumps between the insert and the laminate are avoided.
