Description
Die Erfindung betrifft eine Gleitringdichtung, in Form einer Laufwerkdichtung, bestehend aus einem in einen zugehörigen Aufnahmebereich einsetzbaren Gleit- und/oder Gegenring, der mit einer außerhalb seiner Gleitfläche vorgesehenen zur Aufnahme wenigstens eines elastischen Rollkörpers bestimmten konischen Umfangsfläche versehen ist, wobei der Gleit- und/oder Gegenring mit einem zusätzlichen, sich im Einbauzustand zumindest im Aufnahmebereich abstützenden, Dichtelement in Wirkverbindung steht.The invention relates to a mechanical seal, in Form of a drive seal, consisting of an in an associated receiving area usable sliding and / or Mating ring that with an outside its sliding surface intended for receiving at least one elastic roller body conical peripheral surface is provided, the slide and / or counter ring with an additional, are supported at least in the receiving area in the installed state, Sealing element is in operative connection.
Durch die
Der
Aus der
Die
Bekannten Laufwerkdichtungskonstruktionen ist gemeinsam, daß zusammenbackender Schmutz in den Raum zwischen Gleitringsteg und Elastomerteil gelangt und, wenn der Raum ausgefüllt ist, die Dichtung in ihrer Nachstell- und Bewegungsfreiheit blockiert wird. Dies kann bei bestimmtem Verschleiß der Gleitringe wegen der fehlenden Möglichkeit des Nachrückens zum Ausfall der Dichtung wegen Verlust der Axialkraft führen.Known drive seal designs has in common that caking dirt enters the space between the mechanical seal and the elastomer part and, when the space is filled the seal is blocked in its readjustment and freedom of movement. With certain wear of the slide rings, this can be because of lack of possibility of moving up lead to failure of the seal due to loss of axial force.
Der Erfindung liegt die Aufgabe zugrunde, das Eindringen von Schmutz in diesem Bereich wirkungsvoll zu verhindern, ohne daß im Bereich des Gleit- und/oder Gegenringes aufwendige Bearbeitungen notwendig sind.The invention has for its object that Effectively prevent dirt from entering this area, without Area of the slide and / or counter ring complex machining are necessary.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruch 1 gelöst.This object is achieved by the Features of claim 1 solved.
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.Advantageous further developments of the Subject of the invention can be found in the subclaims.
Abweichend zum Stand der Technik,
insbesondere der
Die einzelnen Dichtlippen des zusätzlichen Dichtelementes stützen sich somit in unterschiedlichen Bereichen einerseits des Gleit- und/oder Gegenringes und andererseits an entsprechenden Gegenflächen des Aufnahmebereiches ab. Da es sich hier um eine statische Dichtung handelt, ist ein berührender Verschleiß zwischen den Dichtlippen und den korrespondierenden Stützbereichen am Gleit- und/oder Gegenring bzw. der Gegenfläche des Aufnahmebereiches nicht gegeben.The individual sealing lips of the additional sealing element support on the one hand in different areas of and / or counter ring and on the other hand on corresponding counter surfaces of the Recording area. Since this is a static seal acts is a touching Wear between the sealing lips and the corresponding support areas on the sliding and / or Mating ring or the counter surface of the recording area is not given.
Einem weiteren Gedanken der Erfindung gemäß ist der verdickte Bereich des zusätzlichen Dichtelementes in seinem entspannten Zustand etwa auf halber Höhe zwischen den radial äußeren Dichtlippen vorgesehen. Das zusätzliche Dichtelement weist somit eine geschwungene Kontur auf die dem gewünschten Effekt, nämlich der Verhinderung des Eindringens von Schmutz in den Bereich zwischen Gleit- und/oder Gegenring sowie elastischem Rollkörper optimal Rechnung trägt.According to a further concept of the invention, the thickened area of the additional sealing element is provided in its relaxed state approximately halfway between the radially outer sealing lips. The additional sealing element has thus a curved contour that optimally takes into account the desired effect, namely the prevention of dirt from penetrating into the area between the sliding and / or counter ring and the elastic rolling element.
Der Erfindungsgegenstand ist anhand eines Ausführungsbeispieles in der Zeichnung dargestellt und wird wie folgt beschrieben. Es zeigen:The subject of the invention is based on of an embodiment shown in the drawing and is described as follows. It demonstrate:
