Description

Öl- und Staubdichtung -;AT@slager mit Staubkammer Es sind Öl- und Staubabdichtungen für Achslagergehäuse, insbesondere von Schienenfahrzeugen, bekannt, bei denen in einer an dem Achslagergehäus.e angebrachten Staubkammer eine Staubabdichtung enthalten ist. Man kennt auch derartige Einrichtungen, bei denen außerdem ein Spritzring mit Schiebesitz auf dem Achsschenkel angebracht ist.Oil and dust seal -; AT @ slager with dust chamber There are oil and Dust seals for axle box housings, in particular for rail vehicles, are known, with a dust seal in a dust chamber attached to the Achslagergehäus.e is included. Such devices are also known in which there is also a splash ring is fitted with a sliding fit on the steering knuckle.

Die vorliegende Erfindung betrifft eine Öl-und Staubabdichtung, bei der die Axialbewegungen des oberhalb des Ölsumpfes angeordneten Spritzringes begrenzt sind. Hierzu ist der Spritzring mit einem Führungsflansch versehen, mit dem er zwischen die innere Staubkainmerwand und das Z-förmige Staubdichtungsgehäuse greift. Durch diese Anordnung wird der Spritzring stets in einer solchen Lage zu der ölaustrittsstelle des Lagers gehalten, daß er das austretende Öl sicher erfaßt und stets wieder in den Ölr aum abschleudert, ohne daß es in die Staubkammer gelangen kann.The present invention relates to an oil and dust seal which limits the axial movements of the splash ring arranged above the oil sump are. For this purpose, the splash ring is provided with a guide flange with which it is between the inner dust chamber wall and the Z-shaped dust seal housing engages. By this arrangement, the splash ring is always in such a position to the oil outlet point of the camp kept that it safely captured the leaking oil and always back in throws off the oil space without it being able to get into the dust chamber.

In der Zeichnung ist der Erfindungsgegenstand in einem senkrechten (Abt. i) und waagerechten Schnitt (Abt. z) durch den hinteren Teil eines Achslagers dargestellt.In the drawing, the subject of the invention is in a vertical position (Section i) and horizontal section (Section z) through the rear part of an axle box shown.

Das Staubdichtungsgehäuse i, das in bekannter Weise aus Holz oder Leichtmetall hergestellt ist, ist an einer Stirnfläche mit einer Dichtungsscheibe z belegt und wird durch die Federeimzchtung 3 gegen die Wandung B der Staubkammer A gepreßt. Für die Abdichtung gegen den Achsschenkel ist in dem Staubdichtungsgehäuse eine Tasche vorgesehen, in der ein .abdichtender Ring q. (Leder, Filz o. dgl.) eingelegt ist. Das Staubdichtungsgehäuse ist Z-förmig gekröpft, so@ daß es gegenüber der Wandung B eine Aussparung 5 frei läßt.The dust seal housing i, which is made of wood or in a known manner Light metal is made, is on one end face with a sealing washer z occupied and is by the Federeimzchtung 3 against the wall B of the dust chamber A pressed. For the seal against the steering knuckle is in the dust seal housing a pocket is provided in which a sealing ring q. (Leather, felt or the like) inserted is. The dust seal housing is bent in a Z-shape so that it faces the wall B leaves a recess 5 free.

Auf dem Achsschenkel befindet sich der Spritzring 6, der in bekannter Weise aus gepreßtem oder gedrehtem Material hergestellt und mit Schiebesitz auf dem Achsschenkel beweglich ist. Er besitzt einen zweckmäßig geneigten Spritzring 7, der in die Ölkammer des Lagergehäuses hineinreicht und oberhalb des Ölsumpfes liegt. Dieser Spritzring fängt das aus dem Lager austretende Öl auf und schleudert es ab, so daß es nicht in das Staubdichtungsgehäuse eintreten kann.On the steering knuckle is the splash ring 6, which is known in Way made of pressed or twisted material and with a sliding fit the steering knuckle is movable. It has an appropriately inclined splash ring 7, which extends into the oil chamber of the bearing housing and above the oil sump lies. This splash ring catches the oil escaping from the bearing and flings it it off so that it cannot enter the dust seal case.

Der Spritzring ist erfindungsgemäß mit einem Führungsflansch 8 versehen, mit dem er in die Kammmer 5 greift, die zwischen der inneren Staubkammerwand B und dem Z-förmigen Staubdichtungsgehäuse gebildet ist.According to the invention, the splash ring is provided with a guide flange 8, with which he engages in the chamber 5 between the inner dust chamber wall B and the Z-shaped dust seal case is formed.

Durch diese Anordnung wird der Spritzring stets in der richtigen Lage gehalten, auch wenn der Achsschenkel sich in axialer Richtung verschiebt. Bei radialen Stößen stößt der Führungsschenkel 8 unmittelbar gegen den Steg des Z-förmigen Dichtungsgehäuses und schiebt dieses trotz der Klemmuirkung der Feder 3 je nach der Bewegung der Achse vor sich her. Hierdurch wird eine zu starke Zusammenpressung des Dichtungsringes. vermieden.This arrangement ensures that the splash ring is always in the correct position held even if the steering knuckle shifts in the axial direction. With radial The guide leg 8 abuts impacts directly against the web of the Z-shaped seal housing and pushes this in spite of the clamping action of the spring 3 depending on the movement of the axis in front of you. This results in excessive compression of the sealing ring. avoided.
