Description
Die Erfindung betrifft ein Dichtungssystem, beinhaltend mehrere relativ zueinander verdrehbare Bauteile, insbesondere Lagerringe eines Großwälzlagers für Windenergieanlagen.The The invention relates to a sealing system including several relatively mutually rotatable components, in particular bearing rings of a slewing bearing for wind turbines.

Der Erfindung liegt die Aufgabe zugrunde, ein Dichtungselement bereit zu stellen, das zur Bildung eines Dichtungssystems mit zwei relativ zueinander verdrehbaren Bauteilen dergestalt in Wirkverbindung bringbar ist, dass keine äußeren Umwelteinflüsse in den inneren Bereich des Dichtraumes der Bauteile gelangen können, gleichzeitig aber auch kein Schmiermittel aus dem Dichtraum in die äußere Umgebung abgegeben wird. Darüber hinaus soll das erfindungsgemäße Dichtungssystem eine hohe Standzeit haben.Of the Invention is based on the object, a sealing element ready to put that to forming a sealing system with two relative such rotatable components such in operative connection can be brought is that no external environmental influences can get into the inner area of the sealing space of the components, but at the same time no lubricant from the sealing chamber into the external environment is delivered. In addition, the inventive Sealing system have a long service life.
Die Aufgabe wird gelöst durch ein Dichtungssystem, beinhaltend mehrere relativ zueinander verdrehbare, mindestens einen Dichtraum bildende Bauteile, insbesondere Lagerringe eines Großwälzlagers für Windenergieanlagen sowie mindestens ein mehrlippiges Dichtungselement, das mindestens einen statischen und mindestens einen dynamischen Dichtbereich aufweist, wobei ein Schenkel des statischen Dichtbereichs fest mit einem der Bauteile verbunden ist und der aus mehreren Dichtlippen bestehende dynamische Dichtbereich an korrespondierenden radialen und axialen Dichtflächen des anderen Bauteils anliegt und wobei das Dichtungselement zusätzlich einen lippenförmig ausgebildeten Stützbereich aufweist, der sich an einer im Dichtraum liegenden Dichtfläche abstützt.The Task is solved by a sealing system, including a plurality of rotatable relative to each other, at least one sealing space forming components, in particular bearing rings of a slewing bearing for wind turbines and at least one mehrlippiges Sealing element, the at least one static and at least has a dynamic sealing area, wherein a leg of the static sealing area is firmly connected to one of the components and the dynamic sealing area consisting of several sealing lips at corresponding radial and axial sealing surfaces the other component is applied and wherein the sealing element in addition a lip-shaped support area has, which is located on a lying in the sealing space sealing surface supported.
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.advantageous Further developments of the subject invention are the dependent claims refer to.
Unter dem Begriff „statischer Dichtbereich” versteht der Fachmann, dass hier keine Relativbewegung zwischen dem Dichtungselement und dem aufnehmenden Bauteil stattfindet. Bei dem „dynamischen Dichtbereich” findet eine Relativbewegung zwischen dem Elastomermaterial (Dichtlippe) des Dichtungselementes und einem rotierenden Bauteil statt.Under understands the term "static sealing area" the expert that here no relative movement between the sealing element and the receiving component takes place. In the "dynamic Dichtbereich "finds a relative movement between the Elastomer material (sealing lip) of the sealing element and a rotating component instead.
Die erfindungsgemäße Mehrlippendichtung kann bei einreihigen und mehrreihigen Kugellagern sowie bei Rollenlagern eingesetzt werden. Das erfindungsgemäße Dichtsystem erfüllt insbesondere folgende Funktionen:
- – die erste an einer radialen Dichtfläche anliegende dynamische Dichtlippe verhindert, dass keine äußeren Umwelteinflüsse in den Dichtraum der Bauteile, insbesondere des Lagers, gelangen können
- – die zweite an einer inneren axialen Dichtfläche anliegende dynamische Dichtlippe verhindert, dass kein Fett an die Umgebung abgegeben wird
- – die zusätzliche innere, an einer radialen Dichtfläche anliegende statische Stützlippe dient den dynamischen Dichtlippen als Abstützung und minimiert das Nachlassen der Dichtlippenvorspannung durch Materialermüdung. Mit dieser Abstützung wird eine Verbesserung der Dichtigkeit der beiden dynamisch wirkenden Dichtlippen herbeigeführt.
- – durch die Stützlippe wird zusätzlich verhindert, dass auch bei einem Schmiermittelüberdruck im Dichtraum der relativ zueinander drehbaren Bauteile, beispielsweise eines Wälzlagers, der dynamisch wirkende Dichtbereich um den statisch wirkenden Dichtbereich herumgeklappt werden kann.
- - The first applied to a radial sealing surface dynamic sealing lip prevents that no external environmental influences in the sealing space of the components, in particular of the bearing, can pass
- - The second applied to an inner axial sealing surface dynamic sealing lip prevents that no grease is discharged to the environment
- - The additional inner, applied to a radial sealing surface static support lip serves the dynamic sealing lips as a support and minimizes the release of the sealing lip bias by material fatigue. With this support, an improvement in the tightness of the two dynamically acting sealing lips is brought about.
- - By the support lip is additionally prevented that even with a lubricant overpressure in the sealing space of the relatively rotatable components, for example a rolling bearing, the dynamically acting sealing area can be folded around the statically acting sealing area.
Von besonderem Vorteil ist, dass die Stützlippe vom Angriffspunkt her tiefer im Dichtraum liegt als die an einem Axialschenkel anliegende dynamisch wirkende Dichtlippe. Infolge der konstruktiven Ausgestaltung wird die Bewegung der dynamisch wirkenden Dichtlippen unter Belastung reduziert.From It is particularly advantageous that the support lip from the point of application her deeper in the sealing chamber than the fitting to an axial leg dynamically acting sealing lip. Due to the structural design becomes the movement of the dynamically acting sealing lips under load reduced.
