Description
Die Erfindung betrifft eine Wälzlager-Drehverbindung für die Maschinenhausla gerung einer Windkraftanlage mit zwei Laufringen und zwischen diesen abrol lenden Wälzkörpern, wobei die Laufringe mittels einer Schraubverbindung mit einer Anschlußkonstruktion derart verbunden sind, daß eine Befestigungsschrau be in einer Bohrung der Anschlußkonstruktion geführt ist.The invention relates to a roller bearing slewing ring for the machine house wind turbine with two races and roll between them ling rolling elements, the races using a screw connection a connecting structure are connected such that a fastening screw be guided in a hole in the adjacent construction.
Eine derartige Wälzlager-Drehverbindung ist aus der DE 37 25 972 A1 vor bekannt. Der Nachteil dieser Drehverbindung besteht darin, daß von den im Maschinenhaus angeordneten Aggregaten, d. h. dem Generator, Generatorge triebe, Bremsen, Blattverstellung und Nachstellgetriebe Schwingungen durch den direkten metallischen Kontakt der Bestandteile der Wälzlager-Drehver bindung weitergeleitet und zum Teil noch verstärkt werden. Derartige Schwin gungen bzw. Körperschall werden dann von der Umgebung derartiger Wind kraftanlagen als störendes Geräusch wahrgenommen.Such a rolling bearing slewing ring is known from DE 37 25 972 A1 known. The disadvantage of this slewing ring is that of the Machine house arranged aggregates, d. H. the generator, generator ge drives, brakes, blade adjustment and adjusting gear vibrations the direct metallic contact of the components of the roller bearing loyalty will be passed on and in some cases strengthened. Such a swine conditions or structure-borne noise are then from the environment of such wind power plants perceived as disturbing noise.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Wälzlager-Drehverbin dung der genannten Art so zu verändern, daß Schwingungen aus dem Maschi nenhaus nicht auf die Anschlußkonstruktion übertragen werden.The invention is therefore based on the object, a rolling bearing rotary joint extension of the type mentioned so that vibrations from the machine can not be transferred to the adjacent construction.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß wenigstens ein Laufring sowohl an seinen beiden Stirnflächen als auch an seiner den Wälzkör pern abgewandten Innenseite mit einer geräuschdämmenden Einlage aus Kunst stoff oder Gummi versehen ist. Durch die Bedeckung des Laufringes mit hoch dämpfenden Kunststoffen oder Gummi wird ein direkter metallischer Kontakt von Anschlußkonstruktion und Wälzlager-Drehverbindung vermieden, so daß die aus den Aggregaten des Maschinenhauses stammenden Schwingungen nicht über die Wälzlager-Drehverbindung an eine weitere Anschlußkonstruktion, beispielsweise in Form eines Ständers, weiter gegeben werden können.According to the invention, this object is achieved in that at least one Race both on its two end faces and on its rolling elements pern away from the inside with a noise-absorbing insert made of art fabric or rubber is provided. By covering the race with high damping plastics or rubber becomes a direct metallic contact Avoided by the connecting structure and roller bearing slewing ring, so that the vibrations coming from the machine house units via the roller bearing slewing ring to another connecting structure, for example in the form of a stand, can be passed on.
Nach Anspruch 2 ist vorgesehen, daß die geräuschdämmende Einlage an den Stirnflächen als Kreisring oder Kreissegment und an der Innenseite als wenig stens ein O-Ring ausgebildet ist, der in einer Nut in der Anschlußkonstruktion angeordnet ist.According to claim 2 it is provided that the noise-absorbing insert to the End faces as a ring or segment of a circle and on the inside as little least an O-ring is formed, which is in a groove in the connecting structure is arranged.
Aus Anspruch 3 geht hervor, daß der Kreisring oder das Kreissegment aufge klebt, aufgespritzt oder durch Verschraubung befestigt sein soll, wobei sämtliche Ausführungsvarianten gleichberechtigt nebeneinander stehen.From claim 3 it appears that the annulus or the segment of a circle is open sticks, sprayed on or fastened by screwing, all Design variants stand side by side on an equal footing.
In Weiterbildung der Erfindung nach dem unabhängigen Anspruch 4 ist vor gesehen, daß die Befestigungsschraube innerhalb der Bohrung der Anschlußkon struktion in radialer Richtung von einer geräuschdämmenden Einlage umgeben ist und zwischen Laufring und Anschlußkonstruktion bzw. zwischen Anschluß konstruktion und Befestigungsschraube in axialer Richtung je eine weitere geräuschdämmende Einlage angeordnet ist. Diese Ausführungsvariante gelangt dann zum Einsatz, wenn einer der beiden Laufringe über eine Bohrung direkt mit der Anschlußkonstruktion über die Befestigungsschraube verbunden ist.In a development of the invention according to independent claim 4 is before seen that the mounting screw within the bore of the conn structure in the radial direction surrounded by a noise-absorbing insert is and between the race and connection structure or between connection construction and fastening screw each in the axial direction noise-absorbing insert is arranged. This variant comes then used when one of the two races has a hole directly is connected to the connecting structure via the fastening screw.
Auch ist es nach einem weiteren unabhängigen Anspruch 5 möglich, daß die Befestigungsschraube innerhalb der Bohrung des Laufringes in radialer Richtung von einer geräuschdämmenden Einlage umgeben ist und zwischen Laufring und Anschlußkonstruktion bzw. Laufring und Befestigungsschraube in axialer Rich tung je eine weitere geräuschdämmende Einlage angeordnet ist. It is also possible according to a further independent claim 5 that the Fastening screw within the bore of the race in the radial direction is surrounded by a noise-absorbing insert and between the race and Connection construction or race and fastening screw in axial direction Another sound-absorbing insert is arranged.
Auch in diesen Fällen ist, wie aus Anspruch 6 ersichtlich, die geräuschdämmen de Einlage zwischen Laufring und Anschlußkonstruktion bzw. Anschlußkon struktion und Befestigungsschraube oder Laufring und Befestigungsschraube als ein Kreisring oder ein Kreisringsegment und innerhalb der Bohrungen als ein O-Ring ausgebildet.In these cases, as can be seen from claim 6, the noise insulation de insert between the race and connecting structure or connecting con structure and mounting screw or race and mounting screw as an annulus or an annulus segment and within the holes as one O-ring formed.
Nach Anspruch 7 ist vorgesehen, daß zwischen dem Schraubenkopf der Befesti gungsschraube und der Anschlußkonstruktion ein Druckring angeordnet ist. Dieser Druckring bewirkt ein gleichmäßige Verteilung der Flächenpressung auf die geräuschdämmende Einlage.According to claim 7 it is provided that between the screw head of the fastener supply screw and the connecting structure a pressure ring is arranged. This pressure ring causes an even distribution of the surface pressure the noise-absorbing insert.
Schließlich ist nach Anspruch 8 vorgesehen, daß die geräuschdämmende Einlage aus Polyoxymethylen besteht und eine Stärke von 1 mm aufweist. Polyoxymethylen zählt zur Gruppe der Polyazetale und ist ein Homo- bzw. Copolymere auf Basis von Formaldehyd. Dieser Kunststoff findet auf fast allen Gebieten der Technik eine weite Verbreitung und zeichnet sich durch eine besonders gute Dämmwirkung aus. Die Stärke der Dämmschicht von 1 mm hat den Vorteil, daß gegenüber dickeren Kunststoffmaterialien ein Fließen im kalten Zustand wesentlich verringert ist, so daß die Vorspannung der Befestigungs schraube erhalten bleibt und somit die Steifheit der Verbindung zwischen Wälzlager-Drehverbindung und Anschlußkonstruktion erhalten bleibt. Natürlich sind auch andere Materialdicken denkbar.Finally, it is provided according to claim 8 that the noise-reducing The insert is made of polyoxymethylene and has a thickness of 1 mm. Polyoxymethylene belongs to the group of polyacetals and is a homo- or Copolymers based on formaldehyde. This plastic is found on almost everyone A wide range of technical fields and is characterized by a particularly good insulation. The thickness of the insulation layer is 1 mm the advantage that a flow in the cold compared to thicker plastic materials Condition is significantly reduced, so that the bias of the attachment screw is retained and thus the stiffness of the connection between Rolling bearing slewing ring and connection structure is retained. Naturally other material thicknesses are also conceivable.
