Description
Die Erfindung betrifft einen Lippendichtungsring mit einer an einem Dichtungsgehäuse aufgehängten elastischen Dichllippe, welche an einem relativ zum Lippendichtungsring drehbaren, gegenüber dem Dichlungsgehäuse durch eine Formschlußverbindung gegen axiales Verschieben gesicherten Laufring dichtend anliegt.The invention relates to a lip seal ring with an elastic one suspended from a seal housing Seal lip, which is rotatable relative to the lip seal ring, opposite the seal housing The raceway ring is secured against axial displacement by a form-fit connection is applied.
Aus einem herkömmlichen Lippendichtungsring und einem auf eine Welle aufschiebbaren Laufring für die Dichtlippe des Lippendichtungsringes 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 Reparaturfalle leicht auszuwechseln.Consists of a conventional lip seal ring and a race ring that can be pushed onto a shaft for the Sealing lip of the lip seal ring existing construction are well known. The separate Races on the shaft to be sealed have the advantage that the shaft itself does not have any special Surface treatment needs to be subjected. In addition, there is a targeted adaptation of each other sliding materials possible. After all, the sealing ring and the bearing ring are light in the event of repairs to replace.
Durch die US-PS 31 79 424 sowie US-PS 33 41 264 sind bereits Konstruktionen bekannt, bei denen der Laufring mittels zusätzlicher Halteteile mit dem Dichtungsgehäuse durch Formschluß zu einer Einbaiicinheit verbindbar sind. Die nach dem axialen Ineinanderschieben von Dichtung und Laufring erforderlichen, weiteren Arbeitsschritte sowie die Notwendigkeit zusätzlicher Teile zum axialen Halten des Laufringes ergeben eine aufwendige Dichtungseinheit.Through the US-PS 31 79 424 and US-PS 33 41 264 constructions are already known in which the Running ring by means of additional holding parts with the seal housing by means of a form fit to form an installation unit are connectable. The required after the axial sliding of the seal and the race further work steps as well as the need for additional parts to hold the axially The raceway results in a complex sealing unit.
Die DE-PS 11 51 415 offenbart zwar eine Ausbildung einer Dichtungseinheit, bei welcher der Laufring mittels eines radial nach innen gerichteten Gummiwulstes imDE-PS 11 51 415 discloses a design of a sealing unit in which the race by means of a radially inwardly directed rubber bead im
Bereich der Dichtlippe gehalten wird, so daß aufArea of the sealing lip is held so that on
zusätzliche Halteteile verzichtet werden kann. Der dafür notwendige radiale Haltekragen erschwert in Verbindung mit der Montagerichtung des Laufringes in das Dichtungsgehäuse das Zusammenfügen beider Teile erheblich. Außerdem wird die Dichtlippenkante beim radialen Aufweiten und Durchschieben, insbesondere des Haltekragens des Laufringes, leicht beschädigtadditional holding parts can be dispensed with. The radial retaining collar required for this makes it difficult in Connection with the assembly direction of the race in the seal housing the joining of both parts considerable. In addition, the edge of the sealing lip is, in particular, when it is radially expanded and pushed through of the retaining collar of the raceway, slightly damaged
Der Erfindung liegt die Aufgabe zugrunde, eine fürThe invention has for its object to provide a for
ίο Lagerung, Transport und Montage beider Teile ausreichende, die Dichtlippe des Lippendichtungsringes nicht beeinflussende, einfache Formschlußverbindung zur axialen Arretierung beider Teile zu schaffen.ίο Storage, transport and assembly of both parts Sufficient, simple form-fitting connection that does not affect the sealing lip of the lip seal ring to create axial locking of both parts.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Formschlußverbindung aus mindestens einer außerhalb des Dichtlippenbereiches angeordneten, mit dem Dichtungsgehäuse und/oder dem Laufring verbundenen, federnden Haltekralle besteht ui.d daß zwischen Haltekralle und zugeordnetem Gegenstück des Laufrings ein Dichtspalt vorgesehen ist.According to the invention, this object is achieved in that the interlocking connection consists of at least one arranged outside the sealing lip area, connected to the seal housing and / or the raceway, There is a resilient retaining claw between the retaining claw and the associated counterpart of the raceway a sealing gap is provided.
Zum erleichterten Verhaken der Haltekralle sind die beim Oberschieben einander berührenden Umfangsflächen
abgeschrägt ausgebildet
Ausfübrungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden wie folgt näher
beschrieben. Es zeigtTo facilitate the hooking of the retaining claw, the circumferential surfaces that touch each other when it is pushed over are chamfered
Exemplary embodiments of the invention are shown in the drawing and are described in more detail as follows. It shows
F i g. 1 und 2 je einen Querschnitt durch einen Lippendichtungsring mit Laufring.
Bei den dargestellten Ausführungsbeispielen besteht der jeweils mit 1 bezeichnete Lippendichtungsring aus
einem winkelförmigen, durch ein Metallteil 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 Dichtkante 6 unter dem radialen Druck eines Schraubenzugfederringes 7 auf dem axialen Schenkel 8
eines winkelförmigen, relativ zum Lippendichtungsring umlaufenden Laufringes 9 dichtend auf. Der radiale
Schenkel 10 des Laufringes 9 erstreckt sich dabei bodenseitig neben den radialen Schenkel 11 des
Dichtungsgehäuses 3.F i g. 1 and 2 each show a cross section through a lip seal ring with a raceway.
In the illustrated embodiments, the lip seal ring, each designated by 1, consists of an angular seal housing 3 reinforced by a metal part 2, on the radially inwardly directed leg end 4 of which a substantially axially directed sealing lip 5 is vulcanized. The latter rests with its sealing edge 6 under the radial pressure of a helical tension spring ring 7 on the axial leg 8 of an angular running ring 9 that encircles the lip seal ring. The radial leg 10 of the race 9 extends on the bottom side next to the radial leg 11 of the seal housing 3.
Gemäß Fig. 1 weist der Gummikörper des Dichtungsgehäuses eine axiale Verlängerung 12 mit einem radial nach innen gerichteten Gummiwulst 13 auf und bildet somit eine elastische Haltekralle für den radial nach außen gerichteten Gummiwulst 14 des Laufringes 9. Die Umfangsflächen 15, 16 beider Gummiwülste 13, 14 sind derart abgeschrägt, daß sich beide Teile 1 und 9 axial leicht ineinander schieben lassen.According to Fig. 1, the rubber body of the seal housing has an axial extension 12 with a radially inwardly directed rubber bead 13 and thus forms an elastic retaining claw for the radially outwardly directed rubber bead 14 of the race 9. The peripheral surfaces 15, 16 of both rubber beads 13, 14 are beveled in such a way that the two parts 1 and 9 can easily be pushed axially into one another.
Die Formschlußverbindung bei dem in Fig. 2 dargestellten Ausführungsbeispiel besteht aus zwei, im Querschnitt etwa gleich profilierten, axial aus den Stirnflächen 15, 16 des Dichtungsgehäuses 3 und des Laufringes 9 hervorstehenden Gummiwülsten 17,18,die hakenförmig ineinander greifen und somit ein axiales Auseinanderfallen beider Teile verhindern.The positive connection in the embodiment shown in Fig. 2 consists of two, im Cross-section roughly profiled axially from the end faces 15, 16 of the seal housing 3 and the Race ring 9 protruding rubber beads 17,18, which interlock like a hook and thus an axial Prevent both parts from falling apart.
