Abstract

The invention relates to a radial rotary transmission leadthrough for pressure media which are transferred from a fixed housing into a rotating part. In order to provide a radial rotary transmission leadthrough which ensures sound sealing and thus separation of the oil lubrication from the pressure medium even at high pressures, it is proposed that mechanical seal pairs known per se and acting axially against one another be provided between the fixed housing and the rotating part on either side of the radial transmission leadthrough, the adjoining surfaces of the mechanical seals of the one pair acting axially against one another and the inner wedge surfaces of the mechanical seals being lubricated with oil and their radially outer surfaces being acted upon by the pressure medium. <IMAGE>

Description

Die Erfindung betrifft eine RadialdrehdurchführungThe invention relates to a radial rotary feedthrough

für Druckmedien, die von einem festen Gehäuse in ein rotierendes Teil überführt werden.for print media moving from a fixed housing into a rotating part be convicted.

Beim Einsatz von Schrämmaschinen im Untertageeinsatz ist zur Funken- und Staubbekämpfung eine Wasserbedüsung der Schrämmeißel notwendig. Hierbei wird mit einem Druck von 40 bis 200 bar gearbeitet und es ergeben sich bei der Durchführung vom festen Gehäuse zum rotierenden Teil erhebliche Abdichtungsprobleme.When using cutting machines in underground operations, spark and dust control, water spraying of the chipping bits is necessary. Here is worked with a pressure of 40 to 200 bar and it results in the implementation from the fixed housing to the rotating part significant sealing problems.

Aufgabe der Erfindung ist es eine Radialdrehdurchführung zu schaffen, die auch bei hohen Drucken eine einwandfreie Abdichtung und damit Trennung der Ölschmierung vom Druckmedium gewährleistet.The object of the invention is to create a radial rotary feedthrough, which, even at high pressures, ensure perfect sealing and thus separation of the oil lubrication guaranteed by the print medium.

Gelöst wird diese Aufgabe durch die im Kennzeichen des Patentanspruchs angegebenen Merkmale.This problem is solved by the characterizing part of the claim specified features.

Durch das Zusammenwirken, a.h. das axiale Gegeneinanderwirken von jeweils zwei Gleitringdichtungen entsteht zwischen diesen eine Radialdrehdurchführung deren Drehzahlgrenze allein durch die zulässige Gleitgeschwindigkeit der Stahlgleitflächen begrenzt ist. Durch die Ö1-oder Fettschmierung der Innenkeilflächen der Dichtungen wird deren Lebensdauer vergrößert und durch den Druck des Mediums, das in der Durchführung strömt, wird der axiale Anpreßdruck der Gummiringe an die Stahlringe erhöht, wodurch die Dichtwirkung vergrößert wird.By working together, a.h. the axial counteraction of a radial rotary feedthrough is created between each two mechanical seals their speed limit solely through the permissible sliding speed of the steel sliding surfaces is limited. Through the oil or grease lubrication of the inner wedge surfaces of the seals their lifespan is increased and by the pressure of the medium that is in the implementation flows, the axial contact pressure of the rubber rings on the steel rings is increased, whereby the sealing effect is increased.

Die Erfindung soll nachfolgend anhand der Zeichnung erläutert werden, wobei die Drehdurchführung in einem Längsschnitt gezeigt ist.The invention is to be explained below with reference to the drawing, wherein the rotary leadthrough is shown in a longitudinal section.

Durch ein festes Gehäuse 1 wird ein Druckmedium -beispielsweise Kühlwasser für einen Schrämmeißel -zu einem rotierenden Teil 2 geführt und axial durch dieses abgeführt.A pressure medium, for example cooling water, is fed through a fixed housing 1 for a cutting chisel -to a rotating part 2 and axially through this discharged.

Beiderseits der Radialdurchführung 3 sind an sich bekannte axial gegeneinander wirkende Gleitringdichtungspaare vorgesehen, die aus Stahlgleitflächen 5, 6 bzw. 7, 8 und Gummidichtungen 9, 10; 11, 12 bestehen, wobei die angrenzenden Flächen der Gleitringdichtungen 4 des einen Paares axial gegeneinander wirken und die Innenkeilflächen 5, 6 der Gleitringdichtungen 4 mit Ö1 oder Fett geschmiert werden.Both sides of the radial leadthrough 3 are known per se axially against one another acting mechanical seal pairs are provided, which are made of steel sliding surfaces 5, 6 or 7, 8 and rubber seals 9, 10; 11, 12 are made, with the adjacent surfaces of the mechanical seals 4 of the one pair act axially against one another and the inner wedge surfaces 5, 6 of the mechanical seals 4 are lubricated with oil or grease.

Radial von außen werden die Gummiring vom Druckmedium beaufschlagt. Der Mediumdruck (Wasserdruck) erhöht die Anpreßwirkung, so daß weder Ö1 austreten noch Wasser eintreten kann. Auf diese Weise kann auch bei hohem Mediumdruck eine einwandfreie Abdichtung gewährleistet werden.The pressure medium acts on the rubber rings radially from the outside. The medium pressure (water pressure) increases the contact pressure so that neither oil escapes water can still enter. In this way, a perfect sealing can be guaranteed.
