Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung metallischer Gleit- und/oder Gegenringe einer Gleitringdichtung, insbesondere einer Laufwerkdichtung.The invention relates to a method for producing metallic sliding and / or counter-rings of a mechanical seal, in particular a drive seal.
Die technische Zuverlässigkeit hinsichtlich des Dichtverhaltens von Gleitringdichtungen, insbesondere von Laufwerkdichtungen, ist stark abhängig von der Qualität der unterschiedlichen einzelnen Herstellungsschritte sowie deren Spannvorrichtungen. Dies insbesondere im Hinblick darauf, dass durch die jeweilige Spannvorrichtung eine elastische Verformung der Gleitringe eintreten kann, die das spätere Dichtverhalten der Gleitringdichtung beeinflusst.The technical reliability with respect to the sealing behavior of mechanical seals, in particular of drive seals, is highly dependent on the quality of the different individual manufacturing steps and their fixtures. This in particular in view of the fact that an elastic deformation of the sliding rings can occur by the respective clamping device, which influences the subsequent sealing behavior of the mechanical seal.
Gleit- und/oder Gegenringe einer Gleitringdichtung, insbesondere einer Laufwerkdichtung, werden im Einzelgussverfahren hergestellt. Die Bearbeitung der Gleit- und/oder Gegenringe beinhaltet eine aufwändige Verkettung von komplexen Produktionsmaschinen. Dies betrifft diverse Dreh-, Schleif- und Läppvorgänge mit verketteten Waschvorgängen der Gleit- und/oder Gegenringe. Dieser Herstellungsprozess wird als aufwändig und teuer angesehen und bedeutet für größere Stückzahlen einen hohen Handhabungsaufwand.Sliding and / or counter rings of a mechanical seal, in particular a drive seal, are produced by a single casting process. The machining of the sliding and / or counter rings involves an elaborate linking of complex production machines. This concerns various turning, grinding and lapping operations with concatenated washing operations of the sliding and / or counter rings. This manufacturing process is considered to be costly and expensive and means for large quantities a high handling effort.

Der Erfindung liegt die Aufgabe zugrunde, ein alternatives Herstellungsverfahren für Gleit- und/oder Gegenringe einer Gleitringdichtung, insbesondere einer Laufwerkdichtung, bereit zu stellen, das gegenüber dem bisher eingesetzten Herstellverfahren einfacher und kostengünstiger ist, wobei auch elastische Verformungen der Gleit- und/oder Gegenringe bei der mechanischen Bearbeitung weitestgehend vermieden werden.The invention has for its object to provide an alternative manufacturing method for sliding and / or counter-rings of a mechanical seal, in particular a drive seal, to provide, which is simpler and less expensive compared to the manufacturing method previously used, including elastic deformations of the sliding and / or counter rings be largely avoided during mechanical processing.
Die Aufgabe wird gelöst durch ein Verfahren zur Herstellung metallischer Gleit- und/oder Gegenringe einer Gleitringdichtung, insbesondere einer Laufwerkdichtung, indem ein Halbzeug in Form eines Gussrohres durch Schleudergießen erzeugt und das Halbzeug im Bereich einer Bearbeitungsmaschine aufgespannt wird, die innere und/oder die äußere Umfangsfläche sowie die die spätere Gleitfläche ergebende Stirnfläche des Halbzeugs mechanisch bearbeitet und vom Halbzeug abschließend Ringkörper abgetrennt werden.The object is achieved by a method for producing metallic sliding and / or counter-rings of a mechanical seal, in particular a drive seal by a semifinished product produced in the form of a cast tube by centrifugal casting and the semi-finished is clamped in the region of a processing machine, the inner and / or the outer Peripheral surface and the subsequent sliding surface resulting end face of the semi-finished machined and separated from the semi-finished ring body.
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.Advantageous developments of the subject invention can be found in the dependent claims.
Die Herstellung von schleudergegossenen Gussrohren ermöglicht eine hochwertige und kostengünstige Herstellung des Halbzeugs. Eine Bearbeitungsmaschine (Dreh-/Schleifmaschine), beispielsweise mit durchgehender Drehspindel mit Spannsystem am geschleuderten Rohr, ermöglicht eine verzugsfreie Herstellung von Gleit- und/oder Gegenringen und zwar in einer einzigen Werkstückaufspannung.The production of centrifugally cast iron pipes enables high-quality and cost-effective production of the semi-finished product. A processing machine (turning / grinding machine), for example with a continuous rotating spindle with clamping system on the hurled tube, allows distortion-free production of sliding and / or counter-rings in a single workpiece clamping.
Die mechanische Bearbeitung erfolgt stets an der der Aufspannung abgewandten Stirnseite des Halbzeugs, wobei die für die Aufnahme von elastischen Dichtkörpern dienende Umfangsfläche problemlos mit einer entsprechend ausgebildeten Kontur versehen werden kann. Ist der mechanische Bearbeitungsvorgang abgeschlossen, wird der jeweilige Gleit- und/oder Gegenring vom Halbzeug abgestochen und kann bedarfsweise einer weiteren Bearbeitung zugeführt werden.The mechanical processing always takes place at the end facing away from the clamping of the semifinished product, wherein the serving for receiving elastic sealing bodies peripheral surface can be easily provided with a correspondingly shaped contour. If the mechanical machining process is completed, the respective sliding and / or counter-ring is tapped from the semi-finished and can be supplied, if necessary, a further processing.
Eine mögliche weiterführende Bearbeitung kann darin gesehen werden, dass zumindest im Bereich der Gleitfläche eine verschleißfeste Schicht aufgebracht wird.A possible further processing can be seen in the fact that a wear-resistant layer is applied at least in the region of the sliding surface.
Das erfindungsgemäße Verfahren kann sowohl im Einzel- als auch im Mehrspindelverfahren angewendet werden.The inventive method can be used both in single and in multi-spindle process.
Der Erfindungsgegenstand ist anhand eines Ausführungsbeispiels in der Zeichnung dargestellt und wird wie folgt beschrieben. Es zeigen:The subject invention is illustrated by means of an embodiment in the drawing and will be described as follows. Show it:
Nach Fertigstellung der geometrischen Kontur des späteren Gleit- und/oder Gegenrings wird mittels eines nur angedeuteten Abstechwerkzeugs
