Abstract
Description
Die Erfindung betrifft eine Wälzlagerung einer Rotorwelle einer Windkraftanlage.The The invention relates to a roller bearing of a rotor shaft Wind turbine.
Beispielsweise
aus der
Eine Aufgabe der Erfindung ist es, eine verbesserte Wälzlagerung einer Rotorwelle einer Windkraftanlage zu schaffen.A The object of the invention is an improved rolling bearing To create a rotor shaft of a wind turbine.
Gemäß Anspruch 1 beinhaltet eine Wälzlagerung einer Rotorwelle einer Windkraftanlage folgende Merkmale:
- – Ein äußeres Laufbahnelement mit wenigstens einer Laufbahn, auf der Wälzkörper zum Abrollen vorgesehen sind,
- – ein mit einer Grundkonstruktion der Windkraftanlage verbundenes Gehäuseelement zum Aufnehmen des äußeren Laufbahnelements, und
- – ein zwischen dem äußeren Laufbahnelement und dem Gehäuseelement angeordnetes Elastikelement, das entsprechend einem mittleren Abschnitt einer Hohlkugel ausgebildet ist.
- An outer race element having at least one raceway on which rolling elements are provided for unrolling,
- A housing element connected to a basic construction of the wind turbine for receiving the outer raceway element, and
- - An arranged between the outer race member and the housing element elastic element, which is formed according to a central portion of a hollow ball.
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.Thereby, that the elastic element corresponds to a middle section of a Hollow sphere, in particular symmetrically about a center plane of a Hollow ball is formed extending, wherein the hollow ball a spherical outer jacket and a concentric to it spherical inner sheath, finds one for the rotor shaft required angle compensation as well as a compensation of misalignment in the elastic element, which in turn occurs in the Use of non-angularly movable rolling bearing types which can be formed without play in particular a cylindrical roller bearing or double row tapered roller bearing is of particular advantage. Furthermore, advantageously causes the elastic element a vibration as well as a sound decoupling, so that with it Advantage of the elastic element also in terms of low noise emission is cheap.
Dazu ist das Elastikelement insbesondere 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 kann das Elastikelement beispielsweise derart ausgebildet sein, dass in einem Elastomermaterial entsprechend ausgebildete Versteifungselemente entsprechend angeordnet sind.To the elastic element is in particular designed such that the Elastic element under load in the spherical direction itself softer or softer than when loaded in horizontal and vertical direction. In horizontal and vertical direction should the elastic element behave as hard as possible. For this purpose, the elastic element may for example be designed in such a way that in an elastomeric material appropriately trained stiffening elements are arranged accordingly.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus dem im Folgenden beschriebenen Ausführungsbeispiel der Erfindung anhand der Figur.Further Advantages, features and details of the invention will become apparent the embodiment described below the Invention based on the figure.
Dabei
zeigt die Figur als ein Ausführungsbeispiel der Erfindung
einen Längsschnitt 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
Mit
dem Außenmantel des äußeren Laufbahnelements
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 angeordnet.In Other embodiments may, for example the inner intermediate element together with the outer one Raceway element and / or the outer intermediate element integral with the housing element and be made of the same material and / or the outer Intermediate element also has a spherical outer jacket and then in a housing element with accordingly arranged spherically trained inner shell.
