Description
Die Erfindung betrifft eine Wälzlagerung einer Rotorwelle einer Windkraftanlage.The invention relates to a roller bearing of a rotor shaft of a wind turbine.
Beispielsweise aus der
Aus der
Eine Aufgabe der Erfindung ist es, eine verbesserte Wälzlagerung einer Rotorwelle einer Windkraftanlage zu schaffen.An object of the invention is to provide an improved roller bearing of a rotor shaft of a wind turbine.
Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst.The object is solved by the subject matter of claim 1.
Dadurch, dass das Elastikelement entsprechend einem mittleren Abschnitt einer Hohlkugel, der insbesondere symmetrisch um eine Mittenebene einer Hohlkugel erstreckend ausgebildet ist, wobei die Hohlkugel einen sphärischen Außenmantel und einen dazu konzentrischen sphärischen Innenmantel aufweist, findet ein für die Rotorwelle erforderlicher Winkelausgleich wie auch ein Ausgleich von Fluchtungsfehlern im Elastikelement statt, was wiederum beim Einsatz von nicht winkelbeweglichen, spielfrei ausbildbaren Wälzlagerungstypen, insbesondere einer Zylinderrollenlagerung oder zweireihigen Kegelrollenlagerung von besonderem Vorteil ist. Weiterhin bewirkt mit Vorteil das Elastikelement eine Schwingungs- wie auch eine Schallentkopplung, so dass damit Vorteil das Elastikelement auch im Sinne einer geringen Geräuschemission günstig ist.Characterized in that the elastic element corresponding to a central portion of a hollow ball, which is in particular formed symmetrically about a central plane of a hollow ball, wherein the hollow ball has a spherical outer shell and a concentric spherical inner shell, finds a required for the rotor shaft angle compensation as well as a balance of Alignment errors in the elastic element instead, which in turn is when using non-angularly movable, play-free formable Wälzlagerungstypen, in particular a cylindrical roller bearing or double-row tapered roller bearings is particularly advantageous. Furthermore, the elastic element advantageously brings about a vibration as well as a sound decoupling, so that thus the advantage of the elastic element is also favorable in terms of a low noise emission.
Dazu ist das Elastikelement derart ausgebildet, dass das Elastikelement bei Belastung in sphärische Richtung sich nachgiebiger bzw. weicher verhält als bei Belastung in horizontaler und vertikaler Richtung. In horizontaler und vertikaler Richtung soll sich das Elastikelement also möglichst hart verhalten. Dazu ist das Elastikelement derart ausgebildet, dass in einem Elastomermaterial entsprechend ausgebildete Versteifungselemente entsprechend angeordnet sind.For this purpose, the elastic element is designed such that the elastic element behaves more resilient or softer when loaded in the spherical direction than when loaded in the horizontal and vertical directions. In horizontal and vertical direction, the elastic element should behave as hard as possible. For this purpose, the elastic element is designed such that correspondingly formed stiffening elements are arranged correspondingly in an elastomer material.

Dabei zeigt die Figur als ein Ausführungsbeispiel der Erfindung einen Lägsschnitt durch eine Hauptlagerung einer Hauptrotorwelle einer Windkraftanlage. Die Hauptlagerung umfasst dabei das eigentliche Wälzlager, beispielsweise ein Zylinderrollenlager, wobei ein nicht näher dargestelltes inneres Laufbahnelement des Wälzlagers in an sich bekannter Weise auf einem Abschnitt der nicht dargestellten Hauptrotorwelle befestigt ist. Weiterhin umfasst das Wälzlager ein äußeres Laufbahnelement

Das Elastikelement
Das äußere Zwischenelement
In anderen Ausführungsformen können beispielsweise das innere Zwischenelement zusammen mit dem äußeren Laufbahnelement und/oder das äußere Zwischenelement zusammen mit dem Gehäuseelement einstückig und materialeinheitlich ausgebildet sein und/oder das äußere Zwischenelement weist ebenfalls einen sphärischen Außenmantel auf und ist dann in einem Gehäuseelement mit entsprechend sphärisch ausgebildetem Innenmantel angeordnetIn other embodiments, for example, the inner intermediate element together with the outer raceway element and / or the outer intermediate element may be integrally formed with the housing member and of uniform material and / or the outer intermediate member also has a spherical outer shell and is then in a housing element with a correspondingly spherical trained Inner sheath arranged
