Abstract
Die Erfindung betrifft ein Lager zum Lagern eines Maschinenbauteils mit wenigstens einem Ring, dadurch gekennzeichnet, dass an dem Ring wenigstens eine Nut zur Förderung eines Mediums angeordnet ist. Daneben betrifft die Erfindung ein Getriebe. Daneben betrifft die Erfindung ein Kraftfahrzeug.The invention relates to a bearing for supporting a machine component with at least one ring, characterized in that on the ring at least one groove for conveying a medium is arranged. In addition, the invention relates to a transmission. In addition, the invention relates to a motor vehicle.
Description
Die Erfindung betrifft ein. Lager zum Lagern eines Maschinenbauteils mit wenigstens einem Ring. Der Ring dient zum Führen von Wälzkörpern. The invention relates to a. Bearing for storing a machine component with at least one ring. The ring serves to guide rolling elements.
Es ist bekannt, Lager, insbesondere Wälzlager, mit einer Dichtung zu versehen. Dabei wird zwischen dem Innenring und dem Außenring ein Dichtelement angeordnet. Dieses dient zwei verschiedenen Zwecken. It is known to provide bearings, in particular rolling bearings, with a seal. In this case, a sealing element is arranged between the inner ring and the outer ring. This serves two different purposes.
Zum einen kann vorgesehen sein, das Lager mit einem Schmierfett zu schmieren und mittels des Dichtelements wird dann erreicht, dass das Schmierfett nicht durch andere Medien verunreinigt wird. On the one hand can be provided to lubricate the bearing with a grease and by means of the sealing element is then achieved that the grease is not contaminated by other media.
Zum anderen kann vorgesehen sein, dass Dichtelement so zu gestalten, dass ein das Lager umgebendes Medium zum Schmieren in das Lager gelangt. Dann sollen mittels des Dichtelementes Feststoffpartikel oder andere Verunreinigungen des Mediums aus dem Lager herausgehalten werden. Aus der
Bei derart abgedichteten Lagern besteht das Problem, dass der Mediumaustausch zwischen dem Innenraum des Lagers und seinem Außenraum eingeschränkt ist. In such sealed bearings, the problem is that the medium exchange between the interior of the bearing and its exterior space is limited.
Ausgehend hiervon ist es Aufgabe der vorliegenden Anmeldung, ein Lager anzugeben, das einen verbesserten Medienaustausch ermöglicht, wodurch die Schmierung und damit die Lebensdauer des Lagers erhöht wird. Based on this, it is an object of the present application to provide a bearing that allows an improved media exchange, whereby the lubrication and thus the life of the bearing is increased.
Zur Lösung dieses Problems wird ein Lager mit den Merkmalen von Anspruch 1 vorgeschlagen. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen. To solve this problem, a bearing with the features of claim 1 is proposed. Advantageous developments emerge from the subclaims.
Als Kern der Erfindung wird angesehen, dass der Ring des Lagers wenigstens eine Nut zur Förderung eines Mediums aufweist. Als Medium kann jeder Stoff, bevorzugt Flüssigkeiten, verwendet werden, der das Lager umgibt. In einem Getriebe ist beispielsweise ein Schmiermedium vorhanden, das auch mit den Lagern im Getriebe in Kontakt kommt. Dieses Öl bzw. Medium kann mittels der Nut in das Innere des Lagers transportiert werden, so dass die Schmierung des Lagers verbessert ist und dadurch die Haltbarkeit und die Lebensdauer verbessert wird. As the core of the invention is considered that the ring of the bearing has at least one groove for conveying a medium. The medium used may be any substance, preferably liquids, surrounding the bearing. In a transmission, for example, a lubricant is present, which also comes into contact with the bearings in the transmission. This oil or medium can be transported by means of the groove in the interior of the bearing, so that the lubrication of the bearing is improved and thereby the durability and durability is improved.
Vorteilhafterweise kann das Lager ein Wälzlager sein. Die Wälzkörper des Wälzlagers können mittels eines Käfigs geführt werden, sie müssen aber nicht. Die Verwendung eines Laufkäfigs ist lediglich eine vorteilhafte Ausgestaltung. Advantageously, the bearing may be a roller bearing. The rolling elements of the rolling bearing can be guided by means of a cage, but they do not have to. The use of a walking cage is merely an advantageous embodiment.
Vorteilhafterweise kann als wenigstens ein Ring ein Innenring vorgesehen sein. Dann befindet sich wenigstens eine Nut zur Förderung des Mediums an diesem Innenring. Advantageously, can be provided as at least one ring, an inner ring. Then there is at least one groove for conveying the medium to this inner ring.
Weiterhin kann als wenigstens ein Ring ein Außenring vorgesehen sein. Übliche Wälzlager haben sowohl einen Innenring und einen Außenring, es ist jedoch grundsätzlich auch denkbar, dass einer der beiden Ringe wegfällt und dessen Funktion beispielsweise von einem Gehäuseabschnitt übernommen wird. Furthermore, can be provided as at least one ring, an outer ring. Conventional rolling bearings have both an inner ring and an outer ring, but it is also conceivable that one of the two rings is omitted and its function is taken over, for example, by a housing section.
Mit besonderem Vorteil kann das Lager wenigstens ein Dichtelement aufweisen, mit dem ein Innenraum des Lagers abdichtbar ist. Dann ist besonders bevorzugt vorgesehen, dass die wenigstens eine Nut dass wenigstens eine Dichtelement quert und so ein Mediumaustausch über das Dichtelement hinweg in das Lagerinnere erfolgen kann. With particular advantage, the bearing may have at least one sealing element, with which an interior of the bearing is sealable. Then it is particularly preferably provided that the at least one groove that traverses at least one sealing element and so a medium exchange over the sealing element can be carried away into the bearing interior.
Vorteilhafterweise kann die Nut spiralförmig ausgebildet sein. Dabei kann die Spirale entweder in axialer oder in radialer Richtung verlaufen. Die Anzahl der Windungen ist bevorzugt zwischen 1 und 4 Windungen. Je kleiner deren Zahl, desto leichter kann Medium in das Innere des Lagers transportiert werden. Bei größerer Zahl bleiben Schmutzpartikel leichter hängen. Advantageously, the groove can be formed spirally. The spiral can run either in the axial or in the radial direction. The number of turns is preferably between 1 and 4 turns. The smaller the number, the easier it is to transport media to the interior of the warehouse. With larger numbers, dirt particles are more likely to hang.
Vorteilhafterweise können an dem Ring eine Medium einbringende Nut und einer Medium abfördernde Nut vorgesehen sein. Diese Ausgestaltung ist bevorzugt derart weitergebildet, dass das Ölfördervermögen der beiden Nuten gleich groß ist. Dies wird erreicht, indem beide Nuten eine gleiche Breite, Höhe und Länge und damit gleich viele Windungen aufweisen. Die Nuten sind bevorzugt an gegenteiligen Seiten des Rings angeordnet. Advantageously, a medium-introducing groove and a medium-conveying groove may be provided on the ring. This embodiment is preferably developed such that the oil capacity of the two grooves is the same size. This is achieved by both grooves have an equal width, height and length and thus the same number of turns. The grooves are preferably arranged on opposite sides of the ring.
Daneben betrifft die Erfindung ein Getriebe mit wenigstens einem Lager. Dieses zeichnet sich dadurch aus, dass das Lager wie beschrieben ausgebildet ist. In addition, the invention relates to a transmission with at least one bearing. This is characterized in that the bearing is designed as described.
Daneben betrifft die Erfindung ein Kraftfahrzeug mit wenigstens einem Getriebe. Dieses zeichnet sich dadurch aus, dass das Getriebe wie beschrieben ausgebildet ist. In addition, the invention relates to a motor vehicle with at least one transmission. This is characterized in that the transmission is designed as described.
