Description

Die Erfindung betrifft eine Wellendichtung mit aus dünnen Blechen bestehenden Ringen, die mit ihrem dichtenden Rand senkrecht oder annähernd senkrecht zur Wellenachse gegen den. Wellenumfang federnd anstehen und durch Stützringe bis dicht an den Welle numfang geführt sind.The invention relates to a shaft seal with rings consisting of thin metal sheets, those with their sealing edge perpendicular or approximately perpendicular to the shaft axis against the. The circumference of the shaft is resilient and the circumference of the shaft is tight by means of support rings are led.

Hierfür ist es bekannt, dünnwandige, sektorartig unterteilte Blechringe zu zweien in axialer Richtung hintereinander anzuordnen, wobei diese Blechringe in jedem der abzudichtenden Maschinenteile vorgesehen und mit ihrem freien Ende senkrecht zur gegenüberliegenden Fläche des anderen Maschinenteiles gerichtet sind, ohne diese jedoch zu berühren. Diese Blechringe werden vollkommen oder auf einem überwiegenden Teil ihrer Fläche durch Stützkörper gestützt, um ein Umbiegen der Bleche durch den Druck des abzudichtenden Mittels zu vermeiden. Diese Vorrichtung hat jedoch den Nachteil, - daß das Hintanhalten des Austritts des Mittels mit dem höheren Überdruck zwisqhen den Dichtungsfugen nicht erreicht wird, ohne eine Vielzahl von Blechringen in der Wellenrichtung vorzusehen. Aber selbst mit einer Vielzahl angeordneter Ringe ist eine Gewähr für absolutes Dichthalten nicht gegeben, da zwischen Welle und Gehäuse jeweils ein Spalt frei bleibt, durch den das Druckmittel austreten kann.For this purpose, it is known to divide thin-walled sheet metal rings into two sectors to be arranged one behind the other in the axial direction, these sheet metal rings in each of the to be sealed Machine parts provided and with their free end perpendicular to the opposite Surface of the other machine part are directed, but without touching them. These sheet metal rings are perfect or supported on a predominant part of their surface by supporting bodies, in order to prevent the sheets from bending over due to the pressure of the agent to be sealed. However, this device has the disadvantage - That the holding back of the outlet of the agent with the higher overpressure zwisqhen the sealing joints cannot be reached without a large number of sheet metal rings in the direction of the shaft to be provided. But even with a large number of rings arranged there is no guarantee of absolute tightness because A gap remains free between the shaft and the housing, through which the pressure medium can escape can.

Dieser Nachteil wird beim Gegenstand der Erfindung dadurch vermieden, daß die federnden Dichtungsbleche in ihrem Mittelteil parallel zur Wellenachse umgebogen und von den Stützringen so mit Spiel eingeschlossen sind, daß das Mittelteil in Richtung zur Wellenachse in seiner Bewegung gehemmt ist, in der Gegenrichtung dagegen federnd nachgeben kann. Es. ist dabei möglich, das Mittelteil zylindermantelförmig oder in Vieleckform einfach oder mehrfach zu biegen und ihm selbst eine gewisse federnde Wirkung zu erteilen oder es unter .die Einwirkung besonderer Blattfedern o. dgl. zu bringen. Diese Möglichkeit gestattet, für die Dichtungsbleche jeden beliebigen, auch an sich nicht federnden Werkstoff zu verwenden. Es kann hierbei auch in vielen Fällen und bei" entsprechender Ausbildung der Dichtung das Druckmittel für eine Einwirkung auf den axialen Mittelteil herangezogen werden, um die Federwirkung auszuüben oder zu erhöhen.This disadvantage is avoided in the subject matter of the invention in that the resilient sealing plates bent in their middle part parallel to the shaft axis and are enclosed by the support rings with play that the middle part in the direction is inhibited in its movement to the shaft axis, but resilient in the opposite direction can give way. It. it is possible to have the middle part in the shape of a cylinder jacket or in a polygonal shape to bend one or more times and to give it a certain resilient effect or to give it a special effect To bring leaf springs or the like. This possibility allows for the sealing plates any arbitrary, not even per se to use resilient material. It can also be used in many cases and with "appropriate Forming the seal, the pressure medium can be used to act on the axial middle part to exert or increase the spring effect.

Die Zeichnung läßt in Abb. 1, 3, 4 und 6 einige Ausführungsbeispiele im Längsschnitt ersehen. Abb. 2 zeigt eine Stirnansicht verkleinert mit teilweisem Schnitt nach A-B in Abb. i, und Abb. 5 stellt einen verkleinerten Teilausschnitt im Schnitt nach C-D in Abb. 4 dar-.The drawing shows some exemplary embodiments in longitudinal section in Figs. 1, 3, 4 and 6. Fig. 2 shows a reduced front view with a partial section according to AB in Fig. I, and Fig. 5 shows a reduced partial section in section according to CD in Fig. 4.

neten, gegen den Umfang der Welle W annähernd senkrecht gerichteten und abdichtenden Enden oder Schenkeln nachgiebig federnd gehalten, indem sie mit ihrem mittleren Teil a' entweder zylindermantelförmig (Abb. 2) oder in Vieleckform (Abb. S) parallel zur Wellenachse umgebogen und mit ihren äußeren Schenkeln a" in vorzugsweise geteilte Fassungsringe c an dem ruhenden Teil der Maschine befestigt sind (Abb. 1, 3 und 4). Für eine besondere Anpassung der Federkraft an die Betriebserfordernisse kann der mittlere federnde Teil α' mehrmals etwa parallel abgebogen ausgeführt werden (Abb. 3).Neten, towards the circumference of the shaft W approximately perpendicular and sealing ends or legs are resiliently held in that they are bent with their central part a ' either in the shape of a cylinder jacket (Fig. 2) or in a polygonal shape (Fig. S) parallel to the shaft axis and with their outer legs a " are fastened to the stationary part of the machine in preferably split mounting rings c (Fig. 1, 3 and 4). For a special adaptation of the spring force to the operating requirements, the middle resilient part α 'can be bent approximately parallel several times ( Fig. 3).

Ebenso ist es möglich, weichere oder an sich nicht federnde Bleche unter die· Einwirkung einer besonderen Feder b (Abb. 4 und 5) zu halten. Die Fassungsringe werden zweckmäßig zusammen mit den Dichtungsblechen durch Verbindungsbolzen d gehalten.It is also possible to hold softer or non-resilient metal sheets under the action of a special spring b (Figs. 4 and 5). The mounting rings are expediently held together with the sealing plates by connecting bolts d .

In Abb. 6 haben die Dichtungsbleche U-förmigen Querschnitt. Der Steg, der teils die federnden Schenkel a' bildet, wird hier mit seinem mittleren Teil zwischen einem Ring e und besonderen Einsatzteilen / durch Schrauben d' gehalten. In gleicher Weise lassen sich auch Dichtungsbleche mit nur L-förmiger Ouerschnittsform verwenden. Die Ausführungsmöglichkeiten sind durch die gezeichneten Beispiele nicht erschöpft.In Fig. 6 the sealing plates have a U-shaped cross-section. The web, which partly forms the resilient legs a ' , is held here with its central part between a ring e and special insert parts / by screws d' . In the same way, sealing plates with only an L-shaped cross-section can also be used. The design options are not exhausted by the examples shown.
