Abstract

The sealed passage for a rotating shaft (5) has at least one connection (3) through which a fluid medium can pass via a channel (4). The portion with the the connection is able to swivel by means of a bearing housing (2) surrounding the shaft. A casing (7) carries a graphite seal which includes an interspersed graphite seal bushing (8).

Description

Die Erfindung betrifft eine Drehdurchführung mit einem mindestens einen Anschluss und eine Leitung für ein Medium aufweisenden Lagergehäuse, mit einer drehbar relativ zum Lagergehäuse angeordneten Spindel und mit einer eine Graphitdichtung tragenden Trägerhülse.The The invention relates to a rotary feedthrough with at least one a connection and a conduit for a medium having bearing housing, with a rotatably arranged relative to the bearing housing spindle and with a carrier sleeve carrying a graphite gasket.

Drehdurchführungen der eingangs genannten Art sind bespielsweise aus der DE 21 2004 000 027 U1 bekannt, die genutzt werden, um ein Medium über den im Raumkoordinatensystem feststehenden Anschluss in die sich rasch rotierende Spindel führen zu können. Die Übertragung dieses Mediums erfolgt dabei häufig unter sehr hohem Druck, so dass eine angemessene Abdichtung erfolgen muss, wozu es bekannt ist, die Trägerhülse einzusetzen, auf deren Stirnseite ein Graphitring als Graphitdichtung zur Anlage an der Spindel angeordnet ist. Dieser Graphitring ist dabei bei der Trägerhülse radial innen angeordnet und damit dem Raum mit dem hohen Druck ausgesetzt, was häufig dazu führt, dass der Graphitring während des Betriebs von der Trägerhülse gelöst wird, weil wegen der hohen Drücke schon geringe Risse oder Spalte zwischen dem Graphitring und der Trägerhülse dessen Ablösung fördern.Rotating Unions of the type mentioned are recordable from DE 21 2004 000 027 U1 known that used to be a medium over the in the space coordinate system fixed connection in the rapidly rotating spindle lead to can. The transfer This medium is often done under very high pressure, so that an adequate seal is made must, for which it is known to use the carrier sleeve, on the front side a graphite ring arranged as a graphite gasket to rest on the spindle is. This graphite ring is arranged radially inward at the carrier sleeve and thus exposed to the room with the high pressure, which is common leads, that the graphite ring during the operation is released from the carrier sleeve, because of the high pressures even small cracks or gaps between the graphite ring and the Carrier sleeve replacement promote.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Drehdurchführung der eingangs genannten Art so auszubilden, dass eine Beeinträchtigung der Verbindung zwischen der Trägerhülse und der Graphitdichtung vermieden ist.Of the Invention is therefore based on the object, a rotary feedthrough of initially mentioned type so that an impairment the connection between the carrier sleeve and the Graphite seal is avoided.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die Graphitdichtung als die Trägerhülse durchsetzende Graphitdichthülse gestaltet ist, so dass die Trägerhülse auf ihrer Innenseite von der Graphitdichthülse gekapselt ist und damit keine Verbindungsstellen existieren, an denen der von dem Medium ausgeübte Druck eine Separierung der Graphitdichthülse von der Trägerhülse bewirken kann.These The object is achieved according to the invention in that the graphite gasket as the carrier sleeve passing through Graphite sealing sleeve is designed so that the carrier sleeve on its inner side is encapsulated by the graphite sealing sleeve and thus There are no junctions at which of the medium practiced Pressure cause a separation of the graphite sealing sleeve of the carrier sleeve can.

Im folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert; es zeigen:in the Next, the invention will be illustrated on a drawing embodiment explained in more detail; it demonstrate:

1 einen Längsschnitt durch eine erfindungsgemäße Drehdurchführung, und 1 a longitudinal section through a rotary feedthrough according to the invention, and

2 in einer isolierten Darstellung in einem Längsschnitt die Trägerhülse mit der radial innen angeordneten Graphitdichthülse. 2 in an isolated view in a longitudinal section, the carrier sleeve with the radially inner graphite sealing sleeve.

In der Zeichnung ist eine Drehdurchführung 1 dagestellt, die ein Lagergehäuse 2 aufweist, an dem ein Anschluss 3 für ein Medium ausgebildet ist, das durch eine Leitung 4 in dem Lagergehäuse 2 einer drehbar gegenüber diesem Lagergehäuse 2 gelagerten Spindel 5 zugeführt werden kann. Die Spindel 5 ist dabei in dem in der Zeichnung dargestellten Ausführungsbeispiel gegenüber dem Lagergehäuse 2 mittel Kugellager 6 drehbar gelagert, um so die geforderten hohen Drehzahlen erreichen zu können. Zur Abdichtung des Überganges aus der Leitung 4 des Lagergehäuses 2 in die der Spindel 5 ist eine Trägerhülse 7 vorhanden, die durch eine die Trägerhülse 7 durchsetzende Graphitdichthülse 8 innen gekapselt ist, so dass keine eine Separierung fördernde Angriffsmöglichkeit für das Medium zwischen der Trägerhülse 7 und der Graphitdichthülse 8 gegeben ist.In the drawing is a rotary feedthrough 1 daggestellt, which is a bearing housing 2 has, at which a connection 3 is designed for a medium through a conduit 4 in the bearing housing 2 one rotatable relative to this bearing housing 2 stored spindle 5 can be supplied. The spindle 5 is in the embodiment shown in the drawing with respect to the bearing housing 2 medium ball bearings 6 rotatably mounted so as to achieve the required high speeds can. To seal the transition from the line 4 of the bearing housing 2 in the spindle 5 is a carrier sleeve 7 present through a carrier sleeve 7 penetrating graphite sealing sleeve 8th is encapsulated inside, so that no separation promoting attack possibility for the medium between the support sleeve 7 and the graphite sealing sleeve 8th given is.
