Abstract
Description
Die Erfindung betrifft eine Lageranordnung zur Lagerung eines ersten Maschinenteils, insbesondere einer Welle, relativ zu einem zweiten Maschinenteil, insbesondere einem Gehäuse, wobei die Lageranordnung ein erstes und ein zweites Lager umfasst, die voneinander axial beabstandet sind, wobei axial zwischen den beiden Lagern mindestens ein drittes Lager mit mindestens zwei Lagerringen angeordnet ist, wobei das dritte Lager radiale und/oder axiale Lagerkräfte zwischen den beiden Maschinenteilen übertragen kann und wobei zwischen mindestens einem der Lagerringe des dritten Lagers und dem ersten und/oder dem zweiten Maschinenteil direkt oder indirekt eine Schicht aus dämpfendem Material angeordnet ist. Des Weiteren betrifft die Erfindung eine Windkraftanlage mit einer solchen Lageranordnung.The invention relates to a bearing arrangement for mounting a first machine part, in particular a shaft, relative to a second machine part, in particular a housing, wherein the bearing assembly comprises a first and a second bearing, which are axially spaced from each other, wherein at least one axially between the two bearings third bearing is arranged with at least two bearing rings, wherein the third bearing can transmit radial and / or axial bearing forces between the two machine parts and wherein between at least one of the bearing rings of the third bearing and the first and / or the second machine part directly or indirectly a layer of is arranged damping material. Furthermore, the invention relates to a wind turbine with such a bearing assembly.
Eine Lageranordnung dieser Art ist in der
Beispielsweise in Windkraftanlagen werden gattungsgemäße Lageranordnungen eingesetzt. Hierbei kommen häufig zweireihige Kegelrollenlager zum Einsatz.For example, in wind turbines generic bearing assemblies are used. Here are often double row tapered roller bearings are used.
Ein Problem ist es nicht nur bei dieser Anwendung, dass der zu lagernde Rotor einer starken zeitveränderlichen Belastung unterworfen ist, so dass eine erhebliche Anregung zu nachteiligen Schwingungen gegeben ist. Die Lageranordnung selber sowie angrenzende Bauteile werden hierdurch stark belastet und in ihrer Lebensdauer nachteilig beeinflusst.A problem is not only in this application that the rotor to be stored is subjected to a strong time-varying load, so that a significant stimulus to adverse vibrations is given. The bearing assembly itself and adjacent components are thereby heavily loaded and adversely affected in their life.
Der Erfindung liegt daher die Aufgabe zu Grunde, eine gattungsgemäße Lageranordnung und eine Windkraftanlage mit einer solchen vorzuschlagen, mit der es möglich ist, bei stabiler Übertragung der Lagerkräfte einen ruhigeren und schwingungsärmeren Lauf des Lagers sicherzustellen.The invention is therefore based on the object to propose a generic bearing assembly and a wind turbine with such, with which it is possible to ensure a quieter and lower-vibration running of the bearing with stable transmission of the bearing forces.
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass das erste und das zweite Lager frei von einer Schicht aus dämpfendem Material sind, wobei die Schicht aus dämpfendem Material im axialen Bereich zwischen dem ersten und zweiten Lager mittels mindestens zweier Sprengringe axial festgelegt ist, die in Ringnuten in einem der Lagerringe oder einem angrenzenden Bauteil eingreifen und eine direkte oder indirekte axiale Anlagefläche für die Schicht aus dämpfendem Material bilden.The solution of this object by the invention is characterized in that the first and the second bearing are free of a layer of damping material, wherein the layer of damping material is axially fixed in the axial region between the first and second bearing by means of at least two snap rings, which engage in annular grooves in one of the bearing rings or an adjacent component and form a direct or indirect axial bearing surface for the layer of damping material.
Die beiden Lager sind bevorzugt als Kegelrollenlager ausgebildet, wobei die beiden Kegelrollenlager vorzugsweise in O-Anordnung abgeordnet sind.The two bearings are preferably designed as tapered roller bearings, wherein the two tapered roller bearings are preferably seconded in O arrangement.
Zumindest an einem der Lagerringe des dritten Lagers kann axial angrenzend eine Schicht aus dämpfendem Material angeordnet sein, wobei die Schicht aus dämpfendem Material weiterhin an einem im oder am ersten und/oder zweiten Maschinenteil festgelegten Anlaufring angrenzt.At least on one of the bearing rings of the third bearing may be disposed axially adjacent a layer of damping material, wherein the layer of damping material further adjacent to a specified in or on the first and / or second machine part run-on ring.
Zumindest an einem der Lagerringe des dritten Lagers kann auch radial angrenzend eine Schicht aus dämpfendem Material angeordnet sein, wobei die Schicht aus dämpfendem Material am ersten und/oder zweiten Maschinenteil axial festgelegt ist.At least on one of the bearing rings of the third bearing, a layer of damping material can also be arranged radially adjacent, wherein the layer of damping material is axially fixed to the first and / or second machine part.
Das dritte Lager ist gemäß einer bevorzugten Ausgestaltung der Erfindung ein Rillenkugellager, ein Dreipunktlager oder ein Vierpunktlager. Eine andere bevorzugte Ausführungsform sieht als drittes Lager ein Zylinderrollenlager vor.The third bearing is according to a preferred embodiment of the invention, a deep groove ball bearing, a three-point bearing or a four-point bearing. Another preferred embodiment provides as the third camp before a cylindrical roller bearing.
Das dritte Lager kann auch aus mindestens zwei Teillagern bestehen, die axial nebeneinander angeordnet sind. In diesem Falle kann vorgesehen sein, dass das eine Teillager ein nur radiale Lasten übertragendes Zylinderrollenlager ist und das andere Teillager ein axiale und radiale Lasten übertragendes Lager, insbesondere ein Rillenkugellager, ist. Möglich ist es alternativ aber auch, dass die beiden Teillager zwei nur axiale Lasten übertragende Lager, insbesondere Axial-Rillenkugellager, sind.The third bearing may also consist of at least two part bearings, which are arranged axially next to each other. In this case, it may be provided that the one part bearing is a cylindrical roller bearing transmitting only radial loads and the other part bearing is an axial and radial load transmitting bearing, in particular a deep groove ball bearing. Alternatively, it is also possible that the two part bearings are two only axial load bearing bearing, in particular axial deep groove ball bearings.
Die vorgeschlagene Windkraftanlage umfasst einen Rotor, der mit der beschriebenen Lageranordnung gelagert ist.The proposed wind turbine comprises a rotor which is mounted with the bearing arrangement described.
Das vorgeschlagene Konzept stellt also darauf ab, dass das dritte Lager, das zwischen den beiden Lagern vorgesehen und angeordnet ist, als Dämpfungslager auszugestalten, was erfolgt, indem eine Schicht aus dämpfendem Material zwischen einem der Lagerringe und einem der relativ zueinander zu lagernden Bauteile angeordnet wird. Bei dem dämpfenden Material handelt es sich beispielsweise um ein Elastomer- oder Gummimaterial. Bevorzugt ist das dämpfende Material als Ring oder Hülse ausgebildet.The proposed concept is therefore based on designing the third bearing, which is provided and arranged between the two bearings, as a damping bearing, which is done by placing a layer of damping material between one of the bearing rings and one of the components to be supported relative to one another , The damping material is, for example, an elastomer or rubber material. Preferably, the damping material is designed as a ring or sleeve.
Das dritte Lager wirkt also als Schwingungsdämpfer, so dass das Laufverhalten der Lageranordnung verbessert wird.The third bearing thus acts as a vibration damper, so that the running behavior of the bearing assembly is improved.
Erreicht wird dies dadurch, dass das dritte Lager einen vorzugsweise überwiegenden Teil der Schwingungsenergie aufnimmt und über die dämpfende Materialschicht absorbiert. Der Dämpfungseffekt wirkt sich abhängig von der Ausgestaltung wahlweise mehr radial oder mehr axial aus, aber auch kombiniert.This is achieved in that the third bearing receives a preferably predominant part of the vibration energy and absorbed via the damping material layer. The damping effect is dependent on the design optionally more radial or more axial, but also combined.
Das dritte Lager kann an einer geeigneten Stelle der Lageranordnung integriert werden.The third bearing may be integrated at a suitable location of the bearing assembly.
