Description

Die Erfindung betrifft eine Vorrichtung zur Zu- und/oder Abführung von Betriebsmedien zu bzw. von einem mit Tragzapfen versehenen kippbaren Konverter, mit einem an einem Tragzapfen befestigten und zum Tragzapfen achsparallele Kanäle aufweisenden Rotor sowie den Rotor umgebenden ortsfesten Gehäusen, welche radiale Kanäle aufweisen, wobei Umfangsnuten entweder an der Außenseite des Rotors und/oder an der Innenseite der Gehäuse vorgesehen sind, in die jeweils ein radialer Kanal der Gehäuse und ein von einem axialen Kanal des Rotors ausgehender radialer Kanal des Rotors münden.The invention relates to a device for supplying and / or discharging operating media to or from a tiltable converter provided with a support pin, with a rotor fastened to a support pin and having axially parallel channels to the support pin, and stationary housings surrounding the rotor, which have radial channels, wherein circumferential grooves are provided either on the outside of the rotor and / or on the inside of the housing, into each of which a radial channel of the housing and a radial channel of the rotor emanating from an axial channel of the rotor open.

Vorrichtungen dieser Art sind z.B. aus der DE-C 31 49 066 sowie der DE-C 25 59 302 bekannt. Bei diesen bekannten Vorrichtungen ist am Tragzapfen jeweils ein Rotor angeflanscht, an dessen Außenseite mindestens ein ortsfestes Gehäuse aufgezogen ist. Die Kanäle des Rotors sind von Rohren gebildet, die im Inneren des Rotors in Richtung zum Tragzapfen verlegt sind. Zur Zuführung unterschiedlicher Betriebsmedien sind bei den bekannten Vorrichtungen mehrere hintereinander angeordnete Gehäuse gemeinsam auf einem Rotor aufgezogen. Dies hat den Nachteil, daß bei einem Defekt an einer Dichtung zwischen dem Gehäuse und dem Rotor sämtliche Gehäuse über die Rotoraußenfläche abgezogen werden müssen, wobei die noch intakten Dichtungen über die gesamte Baulänge des Rotors bewegt werden, was auch für die Montage gilt. Da die bekannten Einrichtungen aus einer Vielzahl unterschiedlich gestalteter Teile zusammengebaut sind, ist die Lagerhaltung aufwendig. Zudem ist es erforderlich, für jeden Konverter, je nach Anzahl der zuzuführenden Betriebsmedien, spezielle Vorrichtungen zu konstruieren.Devices of this type are known, for example, from DE-C 31 49 066 and DE-C 25 59 302. In these known devices, a rotor is flanged to the trunnion, on the outside of which at least one stationary housing is mounted. The channels of the rotor are formed by tubes which are laid inside the rotor in the direction of the trunnion. In the known devices, several casings arranged one behind the other are mounted together on a rotor to feed different operating media. This has the disadvantage that in the event of a defect in a seal between the housing and the rotor, all of the housings must be removed via the rotor outer surface, the seals which are still intact being moved over the entire length of the rotor, which also applies to assembly. Since the known devices are assembled from a large number of differently designed parts, storage is complex. It is also necessary to design special devices for each converter, depending on the number of operating media to be supplied.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, die einfach herzustellen, zu montieren und zu warten ist. Weiters soll die Vorrichtung universell für unterschiedliche Konverter einsetzbar sein, d. h. unabhängig von der Anzahl der zuzuführenden und abzuführenden Betriebsmedien konstruiert und zusammengebaut werden können.The invention aims to avoid these disadvantages and difficulties and has as its object to provide a device of the type described in the opening paragraph which is simple to manufacture, assemble and maintain. Furthermore, the device should be universally applicable for different converters, i. H. can be designed and assembled regardless of the number of operating media to be supplied and removed.

Diese Aufgabe der Erfindung wird erfindungsgemäß dadurch gelöst, daß die Vorrichtung aus untereinander gleichartig ausgebildeten, jeweils ein Rotor- und ein Statorelement aufweisenden Ringelementen gebildet ist, wobei das Statorelement jedes Ringelementes einen radialen Kanal und das Rotorelement desselben Ringelementes einen radialen Kanal und eine Vielzahl von axialen Kanälen aufweist, von denen einer in den radialen Kanal mündet und endseitig verschlossen ist, wogegen die anderen axialen Kanäle durchgehend ausgebildet sind, und die einzelnen Ringelemente hinsichtlich der durchgehenden axialen Kanäle in Flucht und abgedichtet aneinandergefügt sind. Eine Vorrichtung dieser Art erlaubt einen besonders einfachen Zusammenbau, da lediglich, je nach Anzahl der zuzuführenden Betriebsmedien, Ringelemente aneinandergefügt werden müssen. Durch diese "Systembauweise" ist die Vorrichtung für Konverter mit unterschiedlich vielen Betriebsmedien einsetzbar. Die Lagerhaltung für Ersatzteile ist wesentlich vereinfacht, da die Ringelemente untereinander gleich gestaltet sind und gegeneinander ausgetauscht werden können.This object of the invention is achieved in that the device is formed from mutually identically formed ring elements, each having a rotor and a stator element, the stator element of each ring element having a radial channel and the rotor element of the same ring element having a radial channel and a plurality of axial ones Has channels, one of which opens into the radial channel and is closed at the end, whereas the other axial channels are continuous, and the individual ring elements are aligned and sealed with respect to the continuous axial channels. A device of this type allows particularly simple assembly, since ring elements only have to be joined together, depending on the number of operating media to be supplied. This "system design" means that the device can be used for converters with different operating media. The storage of spare parts is considerably simplified since the ring elements are designed identically to one another and can be exchanged for one another.

Eine besonders einfache Montage an dem Tragzapfen eines Konverters ergibt sich, wenn die Ringelemente auf einem mit dem Tragzapfen verbundenen Tragrohr aufgezogen sind. Vorzugsweise sind die Rotorelemente gegeneinander mittels einer Spanneinrichtung verspannt.A particularly simple assembly on the support pin of a converter is obtained if the ring elements are mounted on a support tube connected to the support pin. The rotor elements are preferably braced against one another by means of a tensioning device.

Um den Spannvorgang und den Zusammenbau einfach durchführen zu können, ist vorteilhaft die Spanneinrichtung von einer am Tragrohr aufschraubbaren Spannmutter gebildet.In order to be able to carry out the clamping process and the assembly easily, the clamping device is advantageously formed by a clamping nut that can be screwed onto the supporting tube.

Die Dichtung der axialen Bohrungen der hintereinander angeordneten Ringelemente wird vorzugsweise mittels Ringbuchsen durchgeführt, die in endseitig der axialen Kanäle angeordneten Ausnehmungen eingesetzt sind.The sealing of the axial bores of the ring elements arranged one behind the other is preferably carried out by means of ring bushings which are inserted in recesses arranged at the end of the axial channels.

Gemäß einer bevorzugten Ausführungsform ist jedes Rotorelement am Statorelement mittels an den beiden Stirnenden angeordneter Wälzlager drehbar gelagert und sind zwischen den Wälzlagern und dem radialen Kanal das Statorelement gegenüber dem Rotorelement dichtende Dichtungen eingesetzt, wobei vorzugsweise die Umfangsnut, die Dichtungen und die Wälzlager am Rotorelement angeordnet sind.According to a preferred embodiment, each rotor element is rotatably mounted on the stator element by means of roller bearings arranged on the two end faces, and seals are used between the roller bearings and the radial channel to seal the stator element with respect to the rotor element, the circumferential groove, the seals and the roller bearings preferably being arranged on the rotor element .

Um die in die Statorelemente einmündenden Zuführungsleitungen nicht zu belasten, weist jedes Statorelement eine Drehmomentenstütze auf, die an einem ortsfesten Stützteil abgestützt ist.In order not to stress the feed lines that open into the stator elements, each stator element has a torque support that is supported on a stationary support part.

Die Erfindung ist nachfolgend anhand der Zeichnung an mehreren Ausführungsbeispielen näher erläutert, wobei Fig. 1 eine schematische, teilweise geschnittene Seitenansicht eines kippbaren Konverters ist, Fig. 2 ein Detail der Fig. 1 in vergrößertem Maßstab und Fig. 3 einen Schnitt gemäß der Linie III-III der Fig. 2 veranschaulicht. Fig. 4 ist eine Seitenansicht der Vorrichtung zur Zuführung der Betriebsmedien und Fig. 5 stellt eine Ansicht in Richtung des Pfeiles V der Fig. 4 dar. In den Fig. 6, 7 und 8 sind in zu Fig. 2 analoger Darstellung Details der erfindungsgemäßen Vorrichtung in vergrößertem Maßstab gemäß weiteren Ausführungsformen gezeigt.The invention is explained in more detail below with reference to the drawing using several exemplary embodiments, FIG. 1 being a schematic, partially sectioned side view of a tiltable converter, FIG. 2 a detail of FIG. 1 on an enlarged scale and FIG. 3 a section along line III -III of Fig. 2 illustrates. Fig. 4 is a side view of the device for supplying the operating media and Fig. 5 is a view in the direction of arrow V of Fig. 4. In Figs. 6, 7 and 8 are analogous to Fig. 2 details of the Device according to the invention shown on an enlarged scale according to further embodiments.

Mit 1 ist ein Konverter bezeichnet, welcher in einem Tragring 2 eingesetzt und gegenüber diesem fixiert ist. Der Tragring 2 ist mittels diametral angeordneter Tragzapfen 3, 4 in nicht näher dargestellten Traglagern kippbar abgestützt. An einem Ende des Tragzapfens 4 ist eine Vorrichtung 5 zur Zu- und/oder Abführung verschiedener Betriebsmedien angeflanscht, wobei zwischen dieser Vorrichtung 5 und dem Tragzapfen 4 eine Verbindungsplatte 6 vorgesehen ist, in die Rohre 7, die sich in zur Achse 8 des Tragzapfens 4 paralleler Richtung in Richtung zum Tragring 2 durch den hohlen Tragzapfen 4 hindurch erstrecken, eingesetzt sind. Diese Rohre sind in untereinander gleichem radialem Abstand 9 von der Achse 8 des Tragzapfens 4 nahe der inneren Begrenzungswand 10 des hohlen Tragzapfens 4 angeordnet. Ihre Anzahl ist je nach den zu- und abzuführenden Betriebsmedien gewählt. An der Verbindungsplatte 6 ist außen ein Flansch 11 befestigt, der mit zu den Rohren 7 korrespondierenden axialen Bohrungen 12 ausgestattet ist, wobei diese Bohrungen 12 mit den Rohren 7 fluchten und gegenüber den in der Verbindungsplatte 6 vorgesehenen, die Rohre verlängernden Bohrungen 6ʹ gedichtet sind. Der Flansch 11 trägt ein an ihm starr montiertes Tragrohr 13, auf dem Ringelemente 14, die jeweils ein Rotor- 15 und ein Statorelement 16 aufweisen, aufgezogen sind, deren Anzahl nach der Anzahl der zu- bzw. abzuführenden Betriebsmedien gewählt ist.1 with a converter is designated, which is inserted in a support ring 2 and fixed with respect to this. The support ring 2 is supported by means of diametrically arranged support pins 3, 4 such that they can be tilted in support bearings (not shown). At one end of the trunnion 4, a device 5 for feeding and / or discharging various operating media is flanged, a connecting plate 6 being provided between this device 5 and the trunnion 4, into the tubes 7, which extend in relation to the axis 8 of the trunnion 4 extend in the direction of the support ring 2 through the hollow support pin 4, are used. These tubes are arranged at the same radial distance 9 from one another from the axis 8 of the trunnion 4 near the inner boundary wall 10 of the hollow trunnion 4. Their number is selected depending on the operating media to be fed in and out. On the connecting plate 6, a flange 11 is fastened on the outside, which is equipped with axial bores 12 corresponding to the tubes 7, these bores 12 being aligned with the tubes 7 and being sealed with respect to the bores 6 'provided in the connecting plate 6 and extending the tubes 6'. The flange 11 carries a support tube 13 rigidly mounted on it, on which ring elements 14, each having a rotor 15 and a stator element 16, are mounted, the number of which is selected according to the number of operating media to be supplied or removed.

Das Statorelement 16 umgibt jeweils ein Rotorelement 15 peripher. In jedes Statorelement 16 mündet eine Betriebsmediumzu- bzw. -ableitung 17. Sämtliche Statorelemente 16 sind mittels Drehmomentstützen 18 (vgl. Fig. 4 und 5) an einem ortsfesten Stützteil 19, der als zur Achse 8 des Tragzapfens 4 parallel angeordneter Querbalken ausgebildet ist, abgestützt.The stator element 16 surrounds a rotor element 15 peripherally. An operating medium supply or discharge line 17 opens into each stator element 16. All the stator elements 16 are connected by means of torque supports 18 (cf. FIGS. 4 and 5) to a stationary support part 19 which is arranged parallel to the axis 8 of the support pin 4 Crossbar is formed, supported.

Die Rotorelemente 15 sind mit zu den Bohrungen 12 des Flansches 11 fluchtend vorgesehenen axialen Kanälen 20 bzw. Bohrungen versehen. In jeweils einen axialen Kanal 20 eines Rotorelementes 15 mündet ein radial gerichteter Kanal 21 bzw. eine radiale Bohrung des Rotorelementes 15, die zum Statorelement 16 hin offen ist und in eine an der Außenfläche des Rotorelementes 15 vorgesehene und das Rotorelement 15 peripher umgebende Umfangsnut 22 mündet. Die Zu- bzw. Ableitung 17, die in einen radialen Kanal 23 bzw. eine Bohrung des Statorelementes 16 übergeht, liegt der Umfangsnut 22 genau gegenüber.The rotor elements 15 are provided with axial channels 20 or bores provided in alignment with the bores 12 of the flange 11. In each axial channel 20 of a rotor element 15, a radially directed channel 21 or a radial bore of the rotor element 15 opens, which is open to the stator element 16 and opens into a circumferential groove 22 provided on the outer surface of the rotor element 15 and peripherally surrounding the rotor element 15 . The inlet or outlet line 17, which merges into a radial channel 23 or a bore of the stator element 16, lies exactly opposite the circumferential groove 22.

Zur Ermöglichung einer reibungsarmen Bewegung des Rotorelementes 15 gegenüber dem Statorelement 16 ist jedes Rotorelement 15 gegenüber dem Statorelement 16 mittels Wälzlager 24 drehbar gelagert, wobei je Ringelement 14 zwei Wälzlager 24, die an den Stirnseiten 25 des Ringelementes 14 angeordnet sind, vorgesehen sind.To enable a low-friction movement of the rotor element 15 with respect to the stator element 16, each rotor element 15 is rotatably supported with respect to the stator element 16 by means of roller bearings 24, two roller bearings 24, which are arranged on the end faces 25 of the ring element 14, being provided for each ring element 14.

Zwischen den Wälzlagern 23 und der Umfangsnut 22 sind bei jedem Ringelement 14 dynamische Dichtungen 26 vorgesehen, die - wie beispielsweise in Fig. 8 dargestellt - als Vier-­Lippen-Dichtungen mit einem speziellen Dichtprofil ausgebildet sind.Between the roller bearings 23 and the circumferential groove 22, dynamic seals 26 are provided in each ring element 14, which - as shown for example in FIG. 8 - are designed as four-lip seals with a special sealing profile.

Derjenige axiale Kanal 20 eines Rotorelementes 15, der in die Umfangsnut 22 mündet, ist an dem vom Tragzapfen 4 abgewendeten Ende verschlossen, beispielsweise indem er das Ringelement nicht zur Gänze durchsetzt, wie in Fig. 2 dargestellt, oder indem er durch einen Deckel 27 verschlossen ist (vgl. Fig. 6). Alle anderen im Rotorelement vorgesehenen axialen Kanäle sind durchgehend ausgebildet, d. h. sie durchsetzen das Rotorelement 15 von einer Stirnseite 25 zur gegenüberliegenden Stirnseite. Zur Abdichtung hintereinanderliegender axialer Kanäle 20 der hintereinander angeordneten Ringelemente 14 dienen statische Dichtungen, die als Ringbuchsen 28 ausgebildet und in endseitig der axialen Kanäle angeordnete ringförmige Ausnehmungen 29 eingesetzt bzw. eingepreßt sind.The axial channel 20 of a rotor element 15 which opens into the circumferential groove 22 is closed at the end facing away from the support pin 4, for example by not completely penetrating the ring element, as shown in FIG. 2, or by being closed by a cover 27 is (see Fig. 6). All other axial channels provided in the rotor element are continuous, ie they penetrate the rotor element 15 from one end face 25 to the opposite end face. For Sealing axial channels 20 one behind the other of the ring elements 14 arranged one behind the other serve static seals which are designed as ring bushings 28 and are inserted or pressed into annular recesses 29 arranged at the end of the axial channels.

Die Rotorelemente sind mittels einer Spanneinrichtung 30 gegeneinander gepreßt bzw. verspannt, wodurch die Ringbuchsen 28 eines Ringelementes in die korrespondierenden Ausnehmungen 29 des benachbarten Ringelementes eingepreßt werden. Die Spanneinrichtung 30 ist beim dargestellten Ausführungsbeispiel als Nut- bzw. Wellenmutter ausgebildet, die auf ein am freien Ende des Tragrohres 13 vorgesehenes Gewinde aufgeschraubt ist.The rotor elements are pressed against one another by means of a clamping device 30, as a result of which the ring bushings 28 of a ring element are pressed into the corresponding recesses 29 of the adjacent ring element. In the exemplary embodiment shown, the tensioning device 30 is designed as a slot nut or shaft nut which is screwed onto a thread provided on the free end of the support tube 13.

Anstelle der in Fig. 2 dargestellten herkömmlichen Wälzlager, die im Detail in Fig. 7 veranschaulicht sind, sind auch andere Konstruktionen denkbar. Gemäß Fig. 6 ist in einer zur Stirnseite 25 und zum Außenumfang offenen Ausnehmung 31 des Rotorelementes 15 ein Innenring 32 mit Führungsbund 33 eingesetzt, der mittels Wälzkörper 34 am Statorelement abgestützt ist. Mittels eines stirnseitig am Rotorelement 15 montierten Halterungsringes 35 werden die Wälzkörper 34 am Herausfallen gehindert.Instead of the conventional roller bearings shown in FIG. 2, which are illustrated in detail in FIG. 7, other constructions are also conceivable. 6, an inner ring 32 with a guide collar 33 is inserted in a recess 31 of the rotor element 15 which is open to the end face 25 and to the outer circumference and which is supported on the stator element by means of rolling elements 34. The rolling elements 34 are prevented from falling out by means of a mounting ring 35 mounted on the end face on the rotor element 15.

Gemäß der in Fig. 8 dargestellten Ausführungsform dient die dort gezeigte dynamische Dichtung 26 auch zur Lagerung des Statorelementes 16 am Rotorelement 15, sodaß keine Wälzkörper erforderlich sind.According to the embodiment shown in FIG. 8, the dynamic seal 26 shown there also serves to mount the stator element 16 on the rotor element 15, so that no rolling elements are required.

Die Umfangnut 22, die bei den in den Fig. 6, 7 und 8 dargestellten Ausführungsbeispielen im Rotorelement vorgesehen ist, kann auch im Statorelement bzw. zum Teil im Statorelement und zum Teil im Rotorelement eingearbeitet sein (vgl. Fig. 2).The circumferential groove 22, which is provided in the rotor element in the exemplary embodiments shown in FIGS. 6, 7 and 8, can also be incorporated in the stator element or partly in the stator element and partly in the rotor element (cf. FIG. 2).

Die erfindungsgemäße Vorrichtung ermöglicht es, das Zentrum des Hohlraumes des Tragzapfens frei zu halten, beispielsweise für eine weitere Mediumzu- bzw. -abführungsleitung. Es ist auch denkbar, an das freie Ende des Tragrohres 13 einen Flansch anzusetzen und zwecks Zu- ­und Abführung weiterer Medien eine weitere Vorrichtung der erfindungsgemäßen Art anzuflanschen, wobei die Dimension der Ringelemente der weiteren Vorrichtung entsprechend dem Innendurchmesser des Tragrohres 13 der ersten Vorrichtung gewählt ist.The device according to the invention makes it possible to keep the center of the cavity of the trunnion free, for example for a further medium supply or discharge line. It is also conceivable to attach a flange to the free end of the support tube 13 and to flange-on a further device of the type according to the invention for the purpose of supplying and removing further media, the dimension of the ring elements of the further device being selected in accordance with the inside diameter of the support tube 13 of the first device .
