Description
Die Erfindung betrifft eine Anordnung zum verschwenkbaren Lagern von Rotorblättern insbesondere einer Windkraftanlage.The The invention relates to an arrangement for the pivotable storage of rotor blades in particular a wind turbine.
Bei Windkraftanlagen ist es beispielsweise bekannt, die Rotorblätter im Bereich einer Rotornabe über Drehverbindungen mit der Nabe zu verbinden und derart mit einem Zahnkranz zu versehen, dass darin eingreifend über einen Elektromotor die Rotorblätter verstellbar sind. Dabei sind die Drehverbindungen vielfach als zweireihige Vierpunktkugeldrehverbindungen ausgebildet und vorgespannt. Für derartige Drehverbindungen sind bei entsprechender Leistung der Windkraftanlage vergleichsweise große Lagerdurchmesser notwendig, was mit Nachteil den Rotorkopf vergleichsweise schwer macht. Weiterhin können bei den Drehverbindungen mit Nachteil False-Brinelling-Probleme auftreten, die eine Lebensdauer der Drehverbindung verkürzen. Darüber hinaus ist die vorausgehend beschriebene technische Lösung, insbesondere bezogen auf die Drehverbindung, technisch aufwendig und damit entsprechend kostenintensiv.at Wind turbines, it is known, for example, the rotor blades in Area of a rotor hub over To connect rotary joints with the hub and so with a To provide sprocket that intervenes via an electric motor the rotor blades are adjustable. The rotary joints are often as double row Four-point ball slewing formed and biased. For such Slewing rings are at the corresponding power of the wind turbine comparatively large bearing diameter necessary, what disadvantage the rotor head comparatively heavy power. Furthermore you can in the rotary joints with disadvantage false-brinelling problems occur, the one Shorten the life of the slewing ring. In addition, the previous one described technical solution, in particular based on the rotary joint, technically complex and therefore costly.
Eine Aufgabe der Erfindung ist es daher, eine Anordnung zum verschwenkbaren Lagern von Rotorblättern insbesondere einer Windkraftanlage derart zu schaffen, dass eine einfache und damit kostengünstige Rotorblattlagerung hoher Lebensdauer erreicht wird.A The object of the invention is therefore to provide an arrangement for pivoting Storage of rotor blades In particular, to create a wind turbine such that a simple and therefore inexpensive Rotor blade bearing high life is achieved.
Die Aufgabe wird durch die Gegenstände der Ansprüche 1 und 5 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The Task is through the objects the claims 1 and 5 solved. Advantageous embodiments are described in the subclaims.
Gemäß Anspruch 5 ist bei einer Anordnung zum Lagern wenigstens eines Rotorblatts, umfassend eine Rotorblattlagerung zum Verschwenken des Rotorblattes um seine Hauptachse, die Rotorblattlagerung als eine Gleitlagerung ausgebildet.According to claim 5 is an arrangement for supporting at least one rotor blade, comprising a rotor blade bearing for pivoting the rotor blade around its main axis, the rotor blade bearing as a plain bearing educated.
Dadurch, dass anstelle der bisher üblichen Kugeldrehverbindungen in Verbindung mit wenigstens im Nabenbereich hohlkörperartig ausgebildeten Rotorblättern nunmehr Gleitlager in Verbindung mit mit den Rotorblättern verbundene Wellen eingesetzt werden, können mit Vorteil die Durchmesser der Gleitlager vergleichsweise klein gehalten werden, so dass sich mit Vorteil ein kompakter Rotorkopf der Windkraftanlage ergibt. Weiterhin sind in Verbindung mit den Gleitlagern mit besonderem Vorteil keine False-Brinelling-Probleme und ein vergleichsweise geringer Verschleiß zu erwarten, so dass Lebensdauern von 20 Jahren und mehr erreichbar sind. Weiterhin sind die Gleitlager gegenüber den üblichen Kugeldrehverbindungen vergleichsweise einfach und damit kostengünstig realisierbar.Thereby, that instead of the usual ball slewing rings in connection with at least in the hub area hollow body-like trained rotor blades now plain bearing in connection with the rotor blades connected Waves can be used Advantageously, the diameter of the sliding bearing comparatively small be held, so that with advantage a compact rotor head the wind turbine results. Furthermore, in conjunction with the Plain bearings with particular advantage no false-brinelling problems and a comparatively low wear too expect, so that lifetimes of 20 years and more achievable are. Furthermore, the bearings are compared to the usual ball slewing rings comparatively simple and thus cost feasible.
Gemäß Anspruch 1 ist bei einer Anordnung zum Lagern wenigstens dreier Rotorblätter, umfassend eine Rotorblattlagerung zum Verschwenken der Rotorblätter um deren jeweilige Hauptachse, diese so ausgebildet, dass die Hauptachse eines der Rotorblätter mit den Hauptachsen der beiden anderen jeweils eine Kreuzungsstelle aufweist, wobei die beiden Kreuzungsstellen zueinander beabstandet sind.According to claim 1 is in an arrangement for supporting at least three rotor blades, comprising a rotor blade bearing for pivoting the rotor blades around their respective main axis, this formed so that the main axis one of the rotor blades with the main axes of the other two each a crossing point having, wherein the two intersection points spaced from each other are.
Dadurch ist es insbesondere in Verbindung mit einer Ausbildung der Rotorblattlagerung als Gleitlagerung mit Vorteil möglich, die Lagerungen aller Rotorblätter inklusive deren Mittel zum Verstellen der Rotorblätter in kompakter und platzsparender Art und Weise auf einem gemeinsamen, beispielsweise scheibenartigen Tragkörper anzuordnen. Dadurch wird mit Vorteil das Gewicht des Rotorkopfes vergleichsweise gering gehalten. Weiterhin ermöglicht besagte Anordnung mit besonderem Vorteil einen gemeinsamen Verstellantrieb für alle Rotorblätter, was wiederum mit entsprechenden Kosten- und Gewichtsvorteilen einhergeht.Thereby it is especially in connection with a training of the rotor blade bearing as sliding bearing with advantage possible, the bearings of all rotor blades including their means for adjusting the rotor blades in compact and space saving way on a common, For example, disc-like support body to arrange. This will Advantageously, the weight of the rotor head kept comparatively low. Furthermore, said Arrangement with particular advantage a common adjustment for all Rotor blades, what again associated with corresponding cost and weight benefits.
