Description
Die Erfindung betrifft eine Dichtungsanordnung zur Abdichtung eines ersten Bauteils gegenüber einem relativ dazu drehbaren zweiten Bauteil. Insbesondere betrifft die Erfindung eine Dichtungsanordnung für ein Wälzlager. The invention relates to a sealing arrangement for sealing a first component relative to a second component rotatable relative thereto. In particular, the invention relates to a seal assembly for a rolling bearing.
Die Abdichtung eines Wälzlagers gegenüber Umwelteinflüssen ist bei vielen Anwendungen notwendig, um eine ausreichende Lebensdauer des Wälzlagers sicherzustellen. Beispielsweise ist es bei Radlagern für Fahrzeuge unabdingbar, die in den Radbefestigungen angeordneten Wälzlager gegenüber Spritzwasser und anderen Verschmutzungen im täglichen Einsatz zu sichern. Üblicherweise werden für diesen Zweck berührende Dichtungen eingesetzt, welche zum Beispiel in der Bauform von Kassettendichtungen bekannt sind, die in die Wälzlager als Dichtungssatz eingesetzt werden können. In den Kassettendichtungen sind meist ein bis zwei in axialer Richtung und ein bis zwei in radialer Richtung berührend anliegende Dichtungslippen positioniert.The sealing of a rolling bearing against environmental influences is necessary in many applications to ensure a sufficient life of the rolling bearing. For example, it is indispensable for wheel bearings for vehicles to secure the arranged in the wheel mountings rolling against splashes and other contaminants in daily use. Usually contact seals are used for this purpose, which are known for example in the design of cassette seals, which can be used in the rolling bearing as a seal set. In the cassette seals usually one to two in the axial direction and one to two in the radial direction touching sealing lips are positioned.
Aus der
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Dichtungsanordnung weiterzuentwickeln.The object of the present invention is to further develop a sealing arrangement.
Die erfindungsgemäße Dichtungsanordnung zur Abdichtung eines ersten Bauteils gegenüber einem relativ dazu drehbaren zweiten Bauteil umfasst eine an dem ersten Bauteil angeordnete erste Dichtung und eine an dem zweiten Bauteil angeordnete zweite Dichtung, wobei die erste Dichtung eine umlaufende Nut aufweist, die dazu vorgesehen ist, bei einer Relativbewegung zwischen dem ersten und dem zweiten Bauteil eine Flüssigkeit aufzunehmen und darüber eine umlaufende Abdichtung auszubilden.The sealing arrangement according to the invention for sealing a first component relative to a second component that is rotatable relative thereto comprises a first seal arranged on the first component and a second seal arranged on the second component, wherein the first seal has a circumferential groove which is provided at one Relative movement between the first and the second component to receive a liquid and form a peripheral seal over it.
Mit anderen Worten bilden die beiden Dichtungen einen Dichtungsraum aus, der insbesondere über die mit einer Flüssigkeit, insbesondere Wasser aus der Umgebung gefüllte Nut abgeschottet wird. Durch eine relative Rotation der beiden Bauteile zueinander wird vorhandenes Wasser radial nach außen katapultiert und in der Nut gesammelt. Dadurch wird automatisch ein umlaufender Wasserfilm in der Nut ausgebildet. Mithin ist die Dichtungsanordnung insbesondere hydrodynamisch ausgebildet.In other words, the two seals form a sealing space, which is in particular sealed off via the groove filled with a liquid, in particular water, from the environment. By a relative rotation of the two components to each other existing water is catapulted radially outwards and collected in the groove. As a result, a circumferential water film is automatically formed in the groove. Thus, the seal assembly is particularly hydrodynamic.
Vorzugsweise ragt die zweite Dichtung zumindest teilweise in die umlaufende Nut an der ersten Dichtung hinein. Mithin wird eine Art Siphon ausgebildet, der zur Abschottung des Dichtungsraums von der Umgebung dient.Preferably, the second seal projects at least partially into the circumferential groove on the first seal. Thus, a kind of siphon is formed, which serves to seal off the sealing space from the environment.
Bevorzugt weist die erste Dichtung ein Trägerelement und ein Dichtungselement auf, wobei zumindest das Trägerelement der ersten Dichtung an dem ersten Bauteil angeordnet ist. Ferner bevorzugt weist die zweite Dichtung zumindest ein Trägerelement und optional ein Dichtungselement auf, wobei das Trägerelement der zweiten Dichtung an dem zweiten Bauteil angeordnet ist und das Dichtungselement der ersten Dichtung an dem Trägerelement der zweiten Dichtung dichtend zur Anlage kommt. Das jeweilige Dichtungselement ist insbesondere aus einem elastischen Material, vorzugsweise aus einem Elastomer ausgebildet. Ferner weist das jeweilige Trägerelement eine höhere Festigkeit und Steifigkeit auf als das jeweilige Dichtungselement. Insbesondere ist das jeweilige Trägerelement mit dem jeweiligen Dichtungselement umspritzt.The first seal preferably has a carrier element and a sealing element, wherein at least the carrier element of the first seal is arranged on the first component. Further preferably, the second seal has at least one carrier element and optionally a sealing element, wherein the carrier element of the second seal is arranged on the second component and the sealing element of the first seal sealingly comes to rest on the carrier element of the second seal. The respective sealing element is in particular formed of an elastic material, preferably of an elastomer. Furthermore, the respective carrier element has a higher strength and rigidity than the respective sealing element. In particular, the respective carrier element is encapsulated with the respective sealing element.
