Abstract

Der Erfindung liegt die Aufgabe zugrunde, eine Lageranordnung zur Lagerung eines Rotors einer Windkraftanlage vorzuschlagen, die den Einsatz in großen Windkraftanlagen ermöglicht. Zudem liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zur Überprüfung der Lageranordnung zu offenbaren. Hierzu wird eine Lageranordnung (1) zur Lagerung eines Rotors einer Windkraftanlage, mit einem Rotorabschnitt (3), der mit dem Rotor verbunden und/oder verbindbar ist, als einen ersten Lagerpartner, mit einem Stützabschnitt (4), der mit einer Umgebungskonstruktion verbunden und/oder verbindbar ist, als einen zweiten Lagerpartner, mit einer Mehrzahl von Laufrollen (5), über die der Rotorabschnitt (3) und der Stützabschnitt (4) relativ zueinander um eine Drehachse (2) drehbar gelagert sind, wobei die Laufrollen bezüglich einer Umlaufrichtung um die Drehachse (2) stationär an einem beliebigen der Lagerpartner (3,4) angeordnet sind, vorgeschlagen, wobei die Laufrollen (5) in mindestens einer Radialreihe (8) zur Übertragung von Radialkräften und in mindestens einer Axialreihe (6,7) zur Übertragung von Axialkräften angeordnet sind.
