Description
Die Erfindung betrifft einen Blattanschluss für die Rotorblätter einer Windenergieanlage, 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 Faserverbundwerkstoff gefertigten, aus mehreren aufeinander gelegten Laminatschichten gefertigten Rotorblatts bzw. der Nabe eingesetzt ist und das mit der Nabe bzw. dem Rotorblatt der Windenergieanlage über Bolzen verbunden ist, die in Innengewindebohrungen in den Inserts eingeschraubte Bolzen verbunden sind.The The invention relates to a blade connection for the rotor blades of a Wind energy plant, in which the rotor blades or the hub with at least an insert of a solid material provided in the Root of or made of a fiber composite material, made of several superimposed layers of laminate rotor blade or the hub is inserted and that with the hub or the rotor blade the wind turbine over Bolt is connected in internally threaded holes in the inserts screwed bolts are connected.
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 Energy production by a wind energy plant is based on the transformation the translational air movement energy into rotational energy, the above rotor blades he follows. The rotor blades The wind turbine is at its root end with a rotor hub connected, either directly or via a between rotor blade and Rotor hub arranged leaf bearing. 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 sogenannten Blattanschluss, große statische und dynamische Biegemomente, die damit verbundenen Zug- und Druckkräfte müssen von dem Blattanschluss übertragen werden.at this conversion of the translational air movement energy into rotational energy arise at the connection between the rotor blade and the rotor hub, the so-called blade connection, great static and dynamic Bending moments, the associated tensile and compressive forces must be of transferred to the blade connection become.
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 Verklebungsfläche übertragen werden, die Oberfläche der Inserts muss daher groß dimensioniert sein.It is already known in the laminate construction of the leaf root inserts glue, which is made of a metal or another solid Material are made. This raises the problem that in such glued inserts inserts the forces only over transfer the bond area become, the surface the inserts must therefore be large be.
Der Erfindung liegt die Aufgabe zugrunde, einen Blattanschluss zu schaffen, die eine Übertragung auch hoher Zug- und Druckkräfte erlaubt.Of the Invention has for its object to provide a blade connection, the one transmission too high tensile and compressive forces allowed.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Hauptanspruches gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung an.According to the invention this Problem solved by the features of the main claim. The under claims indicate advantageous embodiments of the invention.
Insbesondere, dass das wenigstens einem Insert im Querschnitt konisch ausgebildet ist, die Umfangsfläche des wenigstens einen Inserts mit einer Mehrzahl von Erhöhungen und/oder Aussparungen versehen ist, sich parallel zu dem Insert erstreckende Laminatschichten im Bereich des Inserts mit einem zu dem Profil des wenigstens einen Inserts komplementären Profils ausgebildet sind, und die Laminatschichten im Bereich des Inserts senkrecht zu ihrer Erstreckung miteinander vernäht sind, löst die Aufgabe.Especially, in that the at least one insert has a conical cross section is, the peripheral surface the at least one insert with a plurality of elevations and / or Recesses is provided, parallel to the insert extending laminate layers in the area of the insert with a to the profile of at least one Complementary inserts Profiles are formed, and the laminate layers in the field of Inserts are sewn together perpendicular to their extent, solve the Task.
Fas Insert kann vollringförmig ausgebildet sein, es können aber auch zwei halbringförmig ausgebildete Inserts oder eine Vielzahl von ringsegmentförmigen Inserts vorgesehen sein.Fas Insert can be full ring be able to do it but also two semi-annular formed inserts or a plurality of ring segmented inserts be provided.
Die Erfindung wird im Folgenden anhand einer Zeichnung erläutert. Dabei zeigt:The Invention will be explained below with reference to a drawing. there shows:
Das – vorzugsweise
metallische – Insert
Ein
zusätzlich
eingebrachtes Faserverstärkungsmaterial
Das
Insert
Es ist möglich – ohne dass die Erfindung darauf beschränkt wäre – einen noch ungetränkten 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 - without that the invention is limited thereto would be - one still soaked Preform first under suitable sewing make the fiber fabric, insert the insert and then the To infuse resin or inject resin, reducing the positive between the laminate layers and the profile of the insert is made.
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 - to produce the halves of the rotor blade in a half shell, to design the laminate layers of the blade root with a profile corresponding thereto in the region of the insert, then insert the semi-annular insert and then the two halves of the rotor blade to put on 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 herzustellen.A third possibility is to provide a plurality of individual inserts, the in the preformed profile of the preform of the rotor blade or the hub are used and then the positive engagement by injecting or Infusing the resin produce.
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.The Conical training of the inserts facilitates the introduction of a into the still soaked, but already sewn together Fasergelege, it causes, on the other hand, that force jumps between the insert and the laminate are avoided.
