Description
Die Erfindung betrifft eine Lagervorrichtung mit einem Spalt und einer Dichtungseinheit, die dazu vorgesehen ist, den Spalt abzudichten. The invention relates to a bearing device with a gap and a sealing unit, which is intended to seal the gap.
Es ist eine Vorrichtung mit einem zweireihigen, fettgeschmierten Kegelrollenlager bekannt. Die Vorrichtung weist einen Spalt auf, welcher zu einem Innenbereich des Kegelrollenlagers führt. Die Vorrichtung weist eine berührungslose Dichtung auf, welche weit vom Lager entfernt angebracht ist und gegen ein Achsteil abdichtet. Die Dichtung ist entweder als Labyrinthdichtung oder als Filzringsdichtung ausgebildet. Die Dichtung wird erst am endgültigen Einsatzort der Vorrichtung relativ zu dem Lager befestigt. Ferner kann eine Dichtungseinheit der Vorrichtung alternativ zu der Dichtung als Dichtungseinheit, welche auch bei einem Betrieb des Kegelrollenlagers, bei dem sich Komponenten des Lagers relativ zueinander bewegen, permanent an ihrer Gegenlauffläche anliegt, ausgebildet sein.It is a device with a double row, grease-lubricated tapered roller bearings known. The device has a gap which leads to an inner region of the tapered roller bearing. The device has a non-contact seal, which is mounted far away from the bearing and seals against an axle. The seal is designed either as a labyrinth seal or as felt ring seal. The seal is only attached to the final use of the device relative to the camp. Furthermore, a sealing unit of the device may alternatively be formed as a sealing unit, which also permanently contacts its mating surface during operation of the tapered roller bearing in which components of the bearing move relative to each other.
Die Aufgabe der Erfindung besteht insbesondere darin, eine gattungsgemäße Lagervorrichtung mit einer hohen Effizienz bereitzustellen. Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Unteransprüchen entnommen werden können.The object of the invention is in particular to provide a generic storage device with a high efficiency. The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention can be taken from the dependent claims.
Es wird eine Lagervorrichtung, insbesondere Wälzlagervorrichtung, mit einem ersten und einem zweiten Flächenbereich, welche einen Spalt bilden, mit wenigstens einer Dichtungseinheit, welche zumindest teilweise zwischen dem ersten und dem zweiten Flächenbereich angeordnet ist und den Spalt abdichtet, und mit wenigstens einem Lagerbauteil vorgeschlagen, welches eine Lauffläche und den ersten Flächenbereich aufweist, wobei die Dichtungseinheit wenigstens ein Filzelement aufweist, welches an der Abdichtung des Spalts zumindest mitwirkt. Mit einer erfindungsgemäßen Ausgestaltung kann eine hohe Effizienz erreicht werden. Insbesondere kann ein geringer Fertigungsaufwand erreicht und eine lange Toleranzkette vermieden werden. Ferner kann insbesondere erreicht werden, dass bei einer Lieferung eines Lagers, welches die Lagervorrichtung aufweist, der Spalt bereits gegen ein Schmutzeindringen durch die Dichtungseinheit geschützt ist, so dass Schutzmaßnahmen gegen Verschmutzung bei der Lieferung, welche notwendig sind, wenn ein permanenter, nicht zum Lager gehörender Verschmutzungsschutz des Spalts erst nach der Lieferung montiert wird, entfallen können. A bearing device, in particular a roller bearing device, having a first and a second surface region which form a gap, with at least one sealing unit which is arranged at least partially between the first and the second surface region and seals the gap, and proposed with at least one bearing component, which has a running surface and the first surface area, wherein the sealing unit has at least one felt element which at least cooperates with the sealing of the gap. With an embodiment according to the invention, a high efficiency can be achieved. In particular, a low production cost can be achieved and a long tolerance chain can be avoided. Furthermore, it can be achieved, in particular, that in the case of delivery of a bearing having the bearing device, the gap is already protected against dirt penetration by the sealing unit, so that protective measures against contamination at delivery, which are necessary if a permanent, not for storage belonging pollution protection of the gap is mounted only after delivery, can be omitted.
Vorzugsweise ist das Lagerbauteil einstückig ausgebildet. Unter "einstückig" soll insbesondere aus einem Guss und/oder aus einer Spritzung und/oder nur unter Zerstörung trennbar verstanden werden. Dadurch kann eine konstruktiv einfache Bauweise erreicht werden.Preferably, the bearing component is integrally formed. By "one piece" should be understood in particular from a cast and / or from a spray and / or separable only with destruction. This allows a structurally simple design can be achieved.
Ferner wird vorgeschlagen, dass das Lagerbauteil ein Wälzlageraußenring oder ein Wälzlagerinnenring ist. Hierdurch kann erreicht werden, dass eine Gegenlauffläche des Filzelements eine Fläche eines Lagerrings ist und insbesondere durch eine Lagerschulter gebildet ist, wodurch eine zusätzliche Präzisionsbearbeitung in Bezug auf Rundlauf und Oberflächengüte zum Hersteller der Gegenlauffläche vermieden werden kann, weil die Fläche des Lagerrings bereits durch eine solche hergestellt wird.It is also proposed that the bearing component is a roller bearing outer ring or a roller bearing inner ring. In this way it can be achieved that a mating surface of the felt element is a surface of a bearing ring and in particular is formed by a bearing shoulder, whereby an additional precision machining with respect to concentricity and surface quality to the manufacturer of mating surface can be avoided because the surface of the bearing ring already by such will be produced.
Mit Vorteil ist bei einem Betriebsvorgang, bei welchem sich der erste Flächenbereich relativ zu dem zweiten Flächenbereich bewegt, die Dichtungseinheit beabstandet von dem ersten Flächenbereich angeordnet. Auf diese Weise kann Verschleiß vermieden und eine Erhitzung durch Reibung zwischen der Dichtungseinheit und dem ersten Flächenbereich verhindert werden.Advantageously, in an operating process in which the first surface region moves relative to the second surface region, the sealing unit is arranged at a distance from the first surface region. In this way, wear can be avoided and heating by friction between the sealing unit and the first surface area can be prevented.
Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Zeichnungen, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages emerge from the following description of the drawing. In the drawing, an embodiment of the invention is shown. The drawings, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.
Eine erste Dichtungseinheit
Ein Lagerbauteil
Die Erstreckungslänge der Nut
Aufgrund der Nähe der Dichtungseinheit zu dem Inneren des Lagers, welches durch die Dichtungseinheit geschützt wird, werden Toleranzketten reduziert. Ferner wird durch die Dichtungseinheit ein Fettaustritt verhindert.Due to the proximity of the seal unit to the interior of the bearing, which is protected by the seal unit, tolerance chains are reduced. Furthermore, a leakage of grease is prevented by the sealing unit.
Außerdem ist die Dichtungseinheit
In einer anderen Ausführung der Erfindung ist denkbar, dass die Dichtungseinheit an dem Wälzlagerinnenring befestigt ist und an einer anderen Schulter der Lagervorrichtung, insbesondere an einer Schulter des Wälzlageraußenrings, anliegt beziehungsweise mit diesem eine Minimalspaltdichtung bildet.
