Abstract
Description
Die Erfindung betrifft ein Verbindungselement als hohlzylindrischer Metallbalg-Wellkörper mit abwechselnd an dessen Außen- bzw. Innenumfang gerundeten, axial aneinander anliegenden Balgwellen, die zusammen den Wellkörper bilden.The The invention relates to a connecting element as a hollow cylindrical Bellows corrugated body with alternately on the outside or inner circumference rounded, axially adjacent bellows shafts, the together the corpuscle form.
Derartige Metallbalg-Wellkörper sind an sich bekannt. Sie dienen unter anderem als Verbindungselemente zum Ausgleich von Rohranschlüssen, die zueinander versetzt sind, sowie zum Ausgleich von Abstandsveränderungen zwischen derartigen Rohranschlüssen.such Bellows corrugated body are known per se. They serve, inter alia, as connecting elements to compensate for pipe connections, which are offset from each other, as well as to compensate for changes in distance between such pipe connections.

Die bekannten Verbindungselemente sind unzureichend für einen Betrieb bei hohen Temperaturen von etwa 1.100 °C und Drücken etwa ab 3 bar, wie sie in Abgaskanälen von Verbren nungsmotoren vorherrschen. Dort behilft man sich mit kostspieligen Flachdichtungen und Packungen, die allerdings im Dauerbetrieb verhältnismäßig rasch schadhaft werden und daher häufig ausgewechselt werden müssen.The known fasteners are insufficient for one Operating at high temperatures of about 1,100 ° C and pressures from about 3 bar, as they in exhaust ducts of combustion engines prevail. There you help yourself costly gaskets and packings, however, in continuous operation relatively quickly be damaged and therefore often have to be replaced.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verbindungselement der eingangs genannten Art zu schaffen, welches sich durch einen einfachen Aufbau und damit niedrige Kosten auszeichnet, welches einfach zu montieren ist und unter den genannten Betriebsbedingungen eine zuverlässige Dichtung gewährleistet.Of the present invention is based on the object, a connecting element to create the type mentioned, which is characterized by a simple Construction and thus low costs, which is easy to assemble and under the operating conditions mentioned a reliable seal guaranteed.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einem dynamischen Verbindungselement der eingangs genannten Art die die axialen Enden des Wellkörpers bildenden Endwellen geschlossen ausgebildet sind und jeweils gratfrei am Innenumfang enden, derart, daß unter axialer Vorspannung des Wellkörpers ein druckdichter Anschluß an glatten Gegenflächen erzielbar ist.These Task is inventively characterized solved, that at a dynamic connecting element of the type mentioned the axial ends of the corrugated body forming end waves are formed closed and each free of burrs end on the inner circumference, such that under axial bias of the corrugated body a pressure-tight connection smooth counter surfaces is achievable.
Mit einem derartigen Wellkörper können fertigungsbedingte Mittenversätze ausgeglichen und Spannungen aufgrund unterschiedlicher Wärmedehnungen problemlos aufgenommen werden, ohne daß zusätzliche Dichtungen zwischen den Endwellen des Wellkörpers und deren Gegenflächen erforderlich sind. Derartige Wellkörper mit üblicher, eng gewundener Wellenbalgform werden je nach Einbau- und Betriebsbedingungen ausgewählt, d.h. derart dimensioniert, daß infolge ihrer Vorspannung die Dichtwirkung gegen eine Dichtfläche auch unter extrem wechselnden Einsatzbedingungen aufrechterhalten bleibt. Der Wellkörper dient dabei als federndes Verbindungselement, welches infolge seiner Montage unter Vorspannung ohne zusätzliche Dichtmittel auskommt.With Such a corrugated body can production-related center offsets balanced and stresses due to different thermal expansions be easily absorbed without additional seals between the end waves of the corrugated body and their counter surfaces required are. Such corrugated body with the usual, tightly wound Wellenbalgform are selected according to installation and operating conditions, i. dimensioned so that due their bias the sealing effect against a sealing surface also is maintained under extremely changing operating conditions. The corrugated body serves as a resilient connecting element, which due to its Mounting under pretension requires no additional sealant.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Endwellen des Wellkörpers durch Einbiegungen zu dessen Innenumfang hin geschlossen sind, so daß eine genaue Anpassung der Endwellen des Wellkörpers an die jeweiligen Gegenflächen gegeben ist.In Another embodiment of the invention is provided that the end shafts of the corrugated body Inward bends are closed to the inner circumference, so that an accurate Adjustment of the end waves of the corrugated body given to the respective mating surfaces is.
Bei Rohranschlüssen mit Gegenflächen am Innenumfang des Wellkörpers ist dabei besonders zweckmäßig, daß die Einbiegungen nach innen längs des Innenumfangs des Wellkörpers durch Endstege verlängert sind.at pipe connections with counter surfaces on the inner circumference of the corrugated body is particularly useful that the bends inwards along the inner circumference of the corrugated body extended by end webs are.
Die zur Gewährleistung der Dichtwirkung zu wählende Vorspannkraft hängt für eine bestimmte Materialstärke nicht nur vom Aufbau des Wellkörpers sondern auch von dessen Einbaulänge ab. Sie beträgt z.B. im Druckbereich bis etwa 1 bar vorteilhaft zwischen 200 und 400 N, bevorzugt etwa 300 N. Unter diesen Voraussetzungen wird die bei Abgasanlagen von Verbrennungsmotoren erforderliche Dichtwirkung gegenüber glatten Gegenflächen der Anschlußteile zuverlässig verwirklicht.The to guarantee the sealing effect to be chosen Preload depends for one certain material thickness not only from the structure of the corrugated body but also of its installation length from. It is e.g. in the pressure range up to about 1 bar advantageously between 200 and 400 N, preferably about 300 N. Under these conditions, the required sealing effect in exhaust systems of internal combustion engines across from smooth counter surfaces the connecting parts reliable realized.
