Abstract
Description
Anschluss- oder Durchführungselement Connecting or feedthrough element
Die Erfindung betrifft ein Anschluss- oder Durchführungselement für ein Rohr, insbesondere eines Abgasrohres, an oder durch eine Wand, insbesondere eine Wand eines schalldämmenden Gehäuses. The invention relates to a connection or feedthrough element for a pipe, in particular an exhaust pipe, on or through a wall, in particular a wall of a sound-insulating housing.
Aus der DE 32 09 306 AI ist eine Rohrdurchführung bekannt, bei der ein Rohr dichtend eine Wandöffnung durchsetzt. Zwischen der Wand und dem Rohr ist eine Manschette vorgesehen, die spannungsfrei gehalten ist. Sie besteht aus einem zylindrischen Abschnitt von etwa gleichem Durchmesser, wie der Rohraußendurchmesser und einem sich daran anschließenden kegelstumpfförmigen Abschnitt, der mittels eines Ringflansches an der Wand befestigt ist. Die Stützfunktion des Rohres übernimmt eine eigens hierfür angebrachte und am Boden befestigte Schale, gegenüber welcher das Rohr verschiebbar ist. Über die Schale können allerdings Schwingungen in den Boden übertragen werden. From DE 32 09 306 Al a pipe feedthrough is known in which a pipe passes through a sealing wall opening. Between the wall and the pipe, a sleeve is provided, which is held tension-free. It consists of a cylindrical portion of approximately the same diameter, as the tube outer diameter and a subsequent frusto-conical portion which is fixed by means of an annular flange on the wall. The support function of the pipe takes over a specially attached and attached to the ground shell, opposite which the tube is displaceable. However, vibrations can be transmitted to the soil via the shell.
Bei der Durchführung eines Abgasrohres einer Brennkraftmaschine durch ein schallabsorbierendes Gehäuse ergibt sich das Problem, dass die Abgasleitung schwingungsfähig durch das schallisolierende Gehäuse hindurchgeführt werden muss, ohne dass Schwingungen in das Gehäuse eingeleitet werden. Ein Luftspalt zwischen Abgasrohr und Gehäuse ist aber mit akustischen Nachteilen verbunden. When carrying out an exhaust pipe of an internal combustion engine through a sound-absorbing housing, there is the problem that the exhaust pipe must be passed through the sound-insulating housing vibratory, without vibrations are introduced into the housing. However, an air gap between the exhaust pipe and the housing is associated with acoustic disadvantages.
Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden und ein Anschlussoder Durchführungselement zur Anbindung eines Rohres an einen Behälter zu schaffen, welches einerseits das Rohr gegen den Innenraum des Behälters abdichtet und andererseits Vibrationen und Wärmeausdehnungen zwischen dem Rohr und Behälter ausgleicht. The object of the invention is to avoid these disadvantages and to provide a connection or feedthrough element for connecting a pipe to a container, which on the one hand seals the tube against the interior of the container and on the other hand compensates for vibrations and thermal expansions between the pipe and container.
Erfindungsgemäß wird dies dadurch erreicht, dass zwischen zumindest einem vorzugsweise im Wesentlichen ringförmigen ersten Flansch und zumindest einem vorzugsweise im Wesentlichen ringförmigen zweiten Flansch zumindest eine flexible, vorzugsweise elastische Membran ausgebildet ist, wobei vorzugsweise der erste Flansch konzentrisch zum zweiten Flansch, insbesondere innerhalb des zweiten Flansches angeordnet ist. According to the invention this is achieved in that between at least one preferably substantially annular first flange and at least one preferably substantially annular second flange at least one flexible, preferably elastic membrane is formed, wherein preferably the first flange concentric to the second flange, in particular within the second flange is arranged.
In einer vorteilhaften ersten Ausführungsvariante ist vorgesehen, dass - im entspannten Zustand - die Membran eben ausgebildet ist, wobei der erste Flansch und der zweite Flansch im Wesentlichen in der gleichen Ebene, vorzugsweise in der Membranebene oder in einer Ebene parallel zur Membranebene, angeordnet sind. - - In an advantageous first embodiment, it is provided that - in the relaxed state - the membrane is flat, wherein the first flange and the second flange are arranged substantially in the same plane, preferably in the membrane plane or in a plane parallel to the membrane plane. - -
Durch die flache Ausbildung der Membran und der Flansche wird einerseits in axialer Richtung Bauraum eingespart und andererseits die freie Beweglichkeit des beispielsweise durch ein Abgasrohres gebildeten Rohres gegenüber dem Behälter nicht behindert. Das Abgasrohr kann somit sowohl axial, als auch radial innerhalb des Anschluss- und Durchführungselementes schwingen, ohne die Bewegungen in den Behälter zu übertragen. Due to the flat design of the membrane and the flanges space is saved on the one hand in the axial direction and on the other hand does not hinder the free movement of the tube formed for example by an exhaust pipe relative to the container. The exhaust pipe can thus oscillate both axially and radially within the connection and feedthrough element, without transmitting the movements in the container.
Um eine feste Anbindung des Anschluss- und Durchführungselementes an den Behälter einerseits und andererseits an das Rohr zu ermöglichen, kann vorgesehen sein, dass der erste und/oder zweite Flansch durch einen starren und/oder formstabilen Ring, vorzugsweise aus Metall, gebildet ist. Für die Befestigung am Rohr bzw. am Behälter können der erste und/oder der zweite Flansch jeweils zumindest eine Befestigungsbohrung aufweisen. In order to enable a fixed connection of the connecting and feedthrough element to the container on the one hand and on the other hand to the tube, it can be provided that the first and / or second flange is formed by a rigid and / or dimensionally stable ring, preferably made of metal. For attachment to the pipe or to the container, the first and / or the second flange may each have at least one mounting hole.
Die Anzahl an Teilen kann vermindert werden, wenn der zweite Flansch durch zumindest einen Rohrflansch des Rohres gebildet ist, wobei vorzugsweise die Membran zwischen zwei miteinander axial fest verbundenen, vorzugsweise miteinander verschraubten Rohrflanschen eingeklemmt ist. The number of parts can be reduced if the second flange is formed by at least one pipe flange of the pipe, wherein preferably the membrane between two axially fixedly connected, preferably clamped together pipe flanges is clamped.
Eine besonders gute akustische Entkoppelung zwischen dem Rohr und der Wand lässt sich erreichen, wenn die Membran zumindest eine, vorzugsweise umlaufende, Faltung zwischen dem ersten und dem zweiten Flansch aufweist. A particularly good acoustic decoupling between the pipe and the wall can be achieved if the membrane has at least one, preferably circumferential, folding between the first and the second flange.
Die Membran kann aus einem flexiblen und/oder elastischen Material, beispielsweise aus temperaturbeständigen Kunststoff, einem beschichteten Gewebe oder aus Metall, bestehen. The membrane may be made of a flexible and / or elastic material, for example made of temperature-resistant plastic, a coated fabric or metal.
Die Erfindung wird im Folgenden anhand der Figuren näher erläutert. Es zeigen schematisch : The invention will be explained in more detail below with reference to FIGS. They show schematically:

Die Fig. 1 zeigt in einer Explosionsdarstellung ein erfindungsgemäßes Anschlussoder Durchführungselement 1 zur Anbindung eines durch ein Abgasrohr 2 gebildeten Rohres an die Wand 3 eines schalldämmenden Gehäuses 30 einer nicht weiter dargestellte Brennkraftmaschine, beispielsweise eines Stromerzeugungsaggregates. Das Anschluss- oder Durchführungselement 1 weist dabei in dieser Ausführung zumindest einen inneren ersten Flansch 4 und zumindest einen äußeren zweiten Flansch 5 auf, wobei die Flansche 4, 5 im Wesentlichen ringförmig ausgebildet sind. Zwischen dem inneren und äußeren Flanschen 4, 5 wird eine Membran 6 aus einem flexiblen und/oder elastischen Material, beispielsweise aus hochtemperaturfestem Kunststoff, einem beschichteten Gewebe oder aus Metall aufgespannt. Die ersten und zweiten Flansche 4, 5 werden durch starre und/oder formstabile Ringe, beispielsweise aus Metall, gebildet, wobei in den Flanschen 4, 5 jeweils Befestigungsbohrungen 7, 8 mit den Achsen 7', 8' zur Befestigung des Abgasrohres 2 am Anschluss- oder Durchführungselement 1 einerseits und zur Befestigung des Anschluss- oder Durchführungselementes 1 am Behälter 3 andererseits vorgesehen sind. Fig. 1 shows an exploded view of an inventive connection or feedthrough element 1 for connecting a pipe formed by an exhaust pipe 2 to the wall 3 of a sound-absorbing housing 30 of an internal combustion engine, not shown, for example, a power generator. The connecting or feedthrough element 1 has in this embodiment at least one inner first flange 4 and at least one outer second flange 5, wherein the flanges 4, 5 are formed substantially annular. Between the inner and outer flanges 4, 5, a membrane 6 made of a flexible and / or elastic material, for example made of high temperature resistant plastic, a coated fabric or metal is clamped. The first and second flanges 4, 5 are formed by rigid and / or dimensionally stable rings, for example made of metal, wherein in the flanges 4, 5 each mounting holes 7, 8 with the axes 7 ', 8' for attachment of the exhaust pipe 2 at the terminal - or feedthrough element 1 on the one hand and for attachment of the connection or feedthrough element 1 on the container 3 on the other hand are provided.
Das Anschluss- und Durchführungselement 1 ist flach ausgebildet, wobei die konzentrisch angeordneten Flansche 4, 5 im Wesentlichen in einer parallel zur Membranebene ε angeordneten Ebene ausgebildet sind. Dadurch wird die Baugröße des Gehäuses 30 in axialer Richtung des Abgasrohres 2 nicht nachteilig beeinflusst. Andererseits gestattet die Ausführung des Anschluss- und Durchführungselementes 1 den Ausgleich von axialen und radialen Schwingungen zwischen dem Abgasrohr 2 und dem Gehäuses 30, so dass Vibrationen des Abgasrohres 2 nicht in das Gehäuses 30 eingeleitet werden. Die Membran 6, welche auch gasdicht ausgebildet sein kann, bewirkt eine akustische Abdichtung des Innenraumes des Gehäuses 30 gegenüber der Umgebung. The connection and feed-through element 1 is formed flat, wherein the concentrically arranged flanges 4, 5 are formed substantially in a plane parallel to the diaphragm plane ε arranged. As a result, the size of the housing 30 in the axial direction of the exhaust pipe 2 is not adversely affected. On the other hand, the design of the connecting and feedthrough element 1 allows the compensation of axial and radial vibrations between the exhaust pipe 2 and the housing 30, so that vibrations of the exhaust pipe 2 are not introduced into the housing 30. The membrane 6, which may also be gas-tight, causes an acoustic seal of the interior of the housing 30 from the environment.
Das in Fig. 1 vereinfacht mit aneinandergefügten Rohrflanschen 2a, 2b gezeichnete Abgasrohr 2 wird mit seinem Rohrflanschen 2a, 2b am ersten Flansch 4 des Anschluss- und Durchführungselementes 1 mit Schrauben 2c so befestigt, dass das Anschluss- und Durchführungselement 1 zwischen den Rohrflanschen 2a, 2b angeordnet ist. Weiters wird das Anschluss- und Durchführungselement 1 mittels des zweiten Flansches 5 an einer Anschlussfläche 3a an der Außenfläche der Wand 3 des Gehäuses 30 mittels nicht weiter dargestellter weiterer Schrauben befestigt. The simplified in Fig. 1 with adjoining pipe flanges 2a, 2b drawn exhaust pipe 2 is attached with its pipe flanges 2a, 2b on the first flange 4 of the connection and feedthrough element 1 with screws 2c so that the connection and feedthrough element 1 between the pipe flanges 2a, 2b is arranged. Furthermore, the connection and feedthrough element 1 is fastened by means of the second flange 5 to a connection surface 3a on the outer surface of the wall 3 of the housing 30 by means of further screws not shown.
Das Anschluss- und Durchführungselement 1 ist somit sowohl mit dem Gehäuse 30, als auch mit dem Abgasrohr 2 fest verbunden . Durch die flexible und/oder - - elastische Membran 6 können Vibrationen und Wärmeausdehnungen ausgeglichen werden, ohne einen akustisch ungünstigen Spalt zwischen dem Gehäuse 3 und dem Abgasrohr 2 entstehen zu lassen. The connection and feedthrough element 1 is thus firmly connected both to the housing 30 and to the exhaust pipe 2. Due to the flexible and / or - Elastic membrane 6 vibrations and thermal expansion can be compensated without causing an acoustically unfavorable gap between the housing 3 and the exhaust pipe 2.
Fig. 2 zeigt eine Ausführung, bei der die Membran 6 direkt zwischen den Rohrflanschen 2a, 2b des Abgasrohres 2 geklemmt ist. Der zweite Flansch 5 wird in diesem Falle durch die beiden Rohrflansche 2a, 2b des Abgasrohres 2 gebildet, welche fest mit dem Abgasrohr 2 verbunden, beispielsweise angeschweißt sein können. Fig. 2 shows an embodiment in which the membrane 6 is clamped directly between the pipe flanges 2 a, 2 b of the exhaust pipe 2. The second flange 5 is formed in this case by the two pipe flanges 2 a, 2 b of the exhaust pipe 2, which can be fixedly connected to the exhaust pipe 2, for example, welded.
In den Fig. 1 und Fig. 2 ist die Membran 6 im entspannten Zustand im Wesentlichen vollkommen eben ausgebildet, wodurch bei Einsatz von flexiblen und elastischen Werkstoffen eine akustische Entkoppelung zwischen den Abgasrohren 2 und dem Gehäuse 30 gelingt. Um auch weniger elastische Werkstoffe, zum Beispiel aus Metall, etwa aus Stahlblech, einsetzen zu können, kann die Membran 6 zumindest eine balgartige umlaufende Faltung 9 zwischen dem ersten und dem zweiten Flansch 4, 5 aufweisen, wie in Fig. 3 dargestellt ist. Dadurch sind Relativbewegungen zwischen dem ersten und zweiten Flansch 4, 5 sowohl in Richtung der Rohrachse 2' (Fig. 4), als auch quer dazu (Fig. 5), sowie Rohrschiefstellungen, möglich. In FIGS. 1 and 2, the membrane 6 is substantially completely flat in the relaxed state, whereby an acoustic decoupling between the exhaust pipes 2 and the housing 30 is achieved when flexible and elastic materials are used. In order to use less elastic materials, for example made of metal, such as sheet steel, the membrane 6 may have at least one bellows-like circumferential fold 9 between the first and the second flange 4, 5, as shown in Fig. 3. As a result, relative movements between the first and second flange 4, 5 both in the direction of the tube axis 2 '(FIG. 4), as well as transversely thereto (FIG. 5), as well as pipe inclinations, are possible.
