Description

Die Erfindung bezieht sich auf einen radial anlaufenden Dichtungsring, der in einer Ringnut der Bohrung eines in Achsrichtung geteilten Gehäuses oder dgl. angeordnet ist und aus zwei in Achsrichtung geteilten Ringhälften besteht.The invention relates to a radially running sealing ring which is in an annular groove of the bore a housing divided in the axial direction or the like. Is arranged and from two divided in the axial direction Ring halves consists.

Zum Beispiel durch die DE-PS 12 64 905 ist eine Dichtung /ur \bdichtung zwischen einem ruhenden Teil und einem sich drehenden Teil bekannt, die aus zwei halbkreislormigen, elastisch verformbaren Dichtungshälften besteht, von denen jede eine an dem sich drehenden Teil dichtend anliegende Dichtlippe aufweist und in einem in Achsrichtung geteilten Gehäuse oder dgl. angeordnet ist.For example, from DE-PS 12 64 905 is a seal The seal between a stationary part and a rotating part is known, which consists of two semicircular, elastically deformable seal halves, each one on the rotating part Has sealing lip and is arranged in a housing or the like divided in the axial direction is.

Diese bekannte Dichtung hat jedoch die Nachteile, daß sie aus einem verhältnismäßig komplizierten und teueren Bauteil besteht und daß im Bereich der Dichtlippen durch die Trennfuge zwischen den Ringteilen in das Gehäuse eindringen können bzw. öl oder Fett aus dem Gehäuse heraustreten kann.However, this known seal has the disadvantages that it consists of a relatively complicated and expensive component and that in the area of the sealing lips through the parting line between the ring parts in the housing can penetrate or oil or grease can escape from the housing.

In der US-PS 31 80 650 ist ferner ein aus zwei in Achsrichtung geteilten Ringhälften bestehender Dichtungsring dargestellt, der in einer Ringnut in der Bohrung eines in Achsrichtung geteilten Gehäuses angeordnet ist. Dieser bekannte Dichtungsring besitzt Ringhälften, die /.. H. aus Gummi gefertigt sind, und weist die gleichen Nachteile auf. wie die eben beschriebene Dichtung.In US-PS 31 80 650 is also one of two in the axial direction split ring halves existing sealing ring shown, which is in an annular groove in the bore a housing divided in the axial direction is arranged. This well-known sealing ring has ring halves, the / .. H. are made of rubber, and has the same Disadvantages on. like the seal just described.

Durch den SKF-Sonderdruck aus »TZ für praktische Metallbearbeitung« 60 (1966) Heft 4, S. 7 ist es weiterhin nicht mehr neu, zur Abdichtung von geteilten Gehäusen Filzstreifen zu verwenden, die separat in das Ober- und Unterteil eingelegt werden. Derartige Filzstreifen sind nicht fest mit dem Gehäuse verankert und können sich bei hohen Umfangsgeschwindigkeiten verschieben.With the SKF special print from »TZ for practical Metalworking «60 (1966) No. 4, p. 7 it is still no longer new, to use felt strips to seal divided housings, which are separately in the upper and Lower part can be inserted. Such felt strips are not firmly anchored to the housing and can become move at high peripheral speeds.

Bekannt ist ferner aus der CH-PS 2 08 602 eine Abdichtung für Lager, die aus einem Blechteil besieht, das mit einem dünnen Belag aus faserigem Material. /. B. Filz, versehen ist und in der Bohrung einen axial nachAlso known from CH-PS 2 08 602 is a seal for bearings made from a sheet metal part covered with a thin layer of fibrous material. /. B. Felt, is provided and one axially in the bore

Filz, verursachen häufig eine /u große Reibung und neigen dazu, bei zunehmender Umfangsgeschwindigkeit und Reibung aufzureißen und sich zu lockern.may have inwardly directed section. Lies made of fibrous material, e.g. B. felt, often cause a / u great friction and tend to increase with increasing peripheral speed and friction to tear open and loosen up.

Eine Flockfaserschicht ist dagegen sehr verschleißfest und bietet zusammen mit Fett einen guten Schul/ gegen insbesondere trockene Verunreinigungen, z. B. Sand. Erde und Zementstaub. Die Fasern, die senkrecht /ur Oberfläche festgehalten sind, liegen nur mit geringem Druck an der Gegenfläche an, so daß die Reibung zu ischen der Welle und der Flockfaserschicht sehr gering ist.A flock fiber layer, on the other hand, is very wear-resistant and, together with grease, offers a good school / against especially dry contaminants, e.g. B. sand. Earth and cement dust. The fibers that are perpendicular / ur Surface are held, are only with little pressure on the mating surface, so that the friction to isch the wave and the flock fiber layer is very small.

Eine bekannte Abdichtung zeigt auch die GB-PS 8 39 731, die aus verhältnismäßig langen Borsten oder dgl. besteht, welche durch eine besondere Klemmvorrichtung zusammengehalten werden müssen.A known seal is also shown in GB-PS 8 39 731, which consists of relatively long bristles or Like. There, which must be held together by a special clamping device.

Der Erfindung liegt die Aufgabe zugrunde, einen aus zwei Ringhälfien bzw. Scheibenhälften bestehenden Dichtungsring der eingangs genannten Art zu schaffen.The invention is based on the object of one consisting of two ring halves or disk halves To create sealing ring of the type mentioned.

der billig herstellbar ist sowie leicht montiert werden kann und bei dem die Trennfugen zwischen den Ringteilen auf einfache Weise abgedichtet sind.which is cheap to manufacture and can be easily assembled and in which the parting lines between the ring parts are sealed in a simple manner.

Diese Aufgabe wird dadurch gelöst, daß in der Bohrung der Ringhälften bzw. Scheibenhülften eine Flockfaserschicht angeordnet ist.This object is achieved in that a flock fiber layer is in the bore of the ring halves or disk sleeves is arranged.

Durch diese erfindungsgemäße Ausbildung des Dichtungsringes wird erreicht, daß sich die Fasern im Bereich der Trennfuge verhaken und eine gute Abdichtung bilden.This inventive design of the sealing ring is achieved that the fibers in the area the parting line hook and form a good seal.
