Description

Die Erfindung betrifft einen Lipf endichlungsring mit einer an einem Dichtungsgehäuse aufgehängten elastivchen Dichtlippe. welche an einem relativ zum Lippeiidichlungsring drehbaren, gegenüber dem Dichtungsgehäuse durch eine Fornischlußverbindiing gegen axiales Vcrsehicc-n gesicherten Laufring dichtend anliegt.The invention relates to a lip endichlungsring with an elastic sealing lip suspended from a seal housing. which at a relative to the Lippeiidichlungsring rotatable, opposite the seal housing Sealing by means of a fornischlußverbindiing against axial Vcrsehicc-n race ring is applied.

Aus einem herkömmlichen l.ippendichiungsring und einem auf eine Welle aufschiebbarr ■ Laufring für die Dichllippc des l.ippcndichlungsrmges bestehende Konstruktion sind allgemein bekannt. Die separaten Laufringe auf der abzudichtenden Welle haben den Vorteil, daß die Welle selbst keiner besonderen Oberflächenbearbeitung unterzogen zu werden braucht. Außerdem ist eine gezielte Anpassung der aufeinander gleitenden Werkstoffe möglich. Schließlich sind Dichtungsring und Laufring im Keparalurfallc leicht auszuwechseln.A conventional oil lip seal ring and a sliding ring for the Dichlipc of the l.ippcndichlungsrmges existing construction are well known. The separate races on the shaft to be sealed have the Advantage that the shaft itself does not need to be subjected to any special surface treatment. In addition, a targeted adaptation of the materials sliding on each other is possible. Finally, there are sealing ring and the raceway can easily be replaced in the case of a Keparalurfallc.

Durch die US-PS 3! 79 424 sowie US PS 33 41 2b4 sind bereits Konstruktionen bekannt, bei denen der Laufring mittels zusätzlicher lliiltcleilc mil dem Dichtungsgehäuse durch l'ormschliiß zu einer Einbaucinheit verbindbar sind. Die nach dem axialen Ineinanderschieben von Dichtung und Laufring erforderlichen, weiteren Arbeitsscheue sowie die Notwendigkeit zusätzlicher Teile zum axialen Halten des l.aufringes ergeben eine aufwendige Dichtlingseinheit.Through the US PS 3! 79 424 and US PS 33 41 2b4 constructions are already known in which the running ring by means of additional lliiltcleilc mil dem Sealing housings can be connected to form a built-in unit by means of a standard fit. The after the axial Nested seal and race ring required, further work shy as well as the need for additional parts to hold the axially l.aufringes result in a complex sealing unit.

Die DF.I'S 11 51 415 offenbart zwar eine Ausbildung einer Dichtungscinhcit. bei welcher der Laufring mittels eines radial nach innen gerichteten Giimniiwulstcs im Bereich der Diehilippe gehalten wird, so daß auf zusätzliche Halleteile verzichtet werden kann. Der dafür notwendige radiale llaltekragen erschwert in Verbindung mit der Montagerichtung des Laufringcs in das Dichtungsgehäuse das Zusammenfügen beider Teile erheblich- Außerdem wird die Dichilippenkante beim radialen Aufveiten und Durchschieben, insbesondere des Haltekragens des Laufringes, leicht beschädigt.DF.I'S 11 51 415 discloses an education a seal kit. in which the race by means of a radially inwardly directed Giimniiwulstcs im Area of the Diehilippe is held, so that additional hall parts can be dispensed with. Of the Radial flange collars required for this make it difficult in connection with the mounting direction of the raceway in the sealing housing the joining of the two parts considerably radial expansion and pushing through, in particular of the retaining collar of the raceway, easily damaged.

Der Erfindung liegt die Aufgabe zugrunde. e;ne für Lagerung, Transport und Montage beider Teile ausreichende, die Dichtlippe des l.ippendichtungsringes nicht beeinflussende, einfache FormschluUverbindung zur axialen Arretierung beider Teile zu schal fen.The invention is based on the object. e ; For storage, transport and assembly of both parts, a simple form-fit connection that does not affect the sealing lip of the oil sealing ring must be created for the axial locking of both parts.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dall die Formschlußverbindung aus mindestens einer außerhalb des Dichilippenbereiches angeordneten, mit dem Dichtungsgehäuse und/oder dem Laufring verbundenen, federnden Haltekralle bestellt und daß zwischen Haltekralle und zugeordnetem Gegenstück des Laufrings ein Dichtspult vorgesehen ist.This object is achieved according to the invention in that the form-locking connection consists of at least one arranged outside of the dichilip region, with the seal housing and / or the race connected, resilient retaining claw ordered and that between Holding claw and associated counterpart of the raceway a sealing coil is provided.

Zum erleichterten Verhaken der Haltekralle sind die beim Überschieben einander berührenden Umfangsfiachen abgeschrägt ausgebildet.To facilitate the hooking of the retaining claw, the circumferential surfaces that touch each other when pushed over are provided bevelled.

Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden wie folgt näher beschrieben. Es zeigtEmbodiments of the invention are in Drawing shown and are described in more detail as follows. It shows

Fig. I und 2 je einen Querschnitt durch einen Lippendichtungsring mit Laufring.Fig. I and 2 each show a cross section through a lip seal ring with a raceway.

Bei den dargestellten Ausführiingsbeispiclen besteht der jeweils mit I bezeichnete Lippendichtungsring aus einem winkelförmigen, durch ein Metallieil 2 versteiften Dichtungsgehäuse 3. an dessen radial nach innen gerichteten Schenkelende 4 eine im wesentlichen axial gerichtete Dichtlippe 5 anvulkanisiert ist. Letztere liegt mit ihrer Dichtkantc 6 unter dem radialen Druck eines Schraubenzugfcdcrringes 7 auf dem axialen Schenkel 8 eines winkelförmigen, relativ zum l.ippcndichtiingsring umlaufenden Laufringes 9 dichtend auf. Der radiale Schenkel 10 des l.aufringes 9 crMrcckl sich dabei bodenseitig neben den radialen ;>c! cnkcl 11 des Dichliingsgehäuses 3.In the case of the execution examples shown the lip sealing ring marked I in each case from an angular, stiffened by a metal part 2 Seal housing 3. at its radially inwardly directed leg end 4 an essentially axially directed sealing lip 5 is vulcanized. The latter is with its sealing edge 6 under the radial pressure of a Screw tightening ring 7 on the axial leg 8 of an angular, relative to the l.ippcndichtiingsring circumferential race 9 sealing on. The radial leg 10 of the l.aufringes 9 crMrcckl is thereby on the bottom next to the radial ones;> c! cnkcl 11 des Sealing housing 3.

Gemäß Ii g. I weist der Gummikorpcr des Dichtiingsgehäuses eine axiale Verlängerung 12 mit einem radial nach innen gerichteten Giimmiwulst 13 auf und bildet somit eine elastische Haltekralle für ilen radial nach außen gerichteten (niinmiwulst 14 des Laufringcs 9. Die Umfangsflächcn 15, Ιβ beider Giimmiwulsle I !, 14 sind derart abgeschrägt, daß sah beide Teile I und 9 axial leicht ineinander schieben lassenAccording to Ii g. I shows the rubber body of the sealing housing an axial extension 12 with a radially inwardly directed Giimmiwulst 13 and thus forms an elastic retaining claw for ilen radially outwardly directed (niinmi bead 14 of the bearing ring 9. The circumferential surfaces 15, β of both Giimmiwulsle I!, 14 are beveled in such a way that saw both parts I and 9 Slightly slide into each other axially
