Abstract

Die Erfindung betrifft eine Anordnung mit einer Vakuumpumpe (1; 100)), welche einen Pumpenflansch (10; 110; 70) aufweist, einer Kammer (2), welche einen Kammerflansch (20; 120) aufweist, mit einer Flanschverbindung zur vakuumdichten Verbindung von Kammer und Vakuumpumpe. Um die Montierbarkeit zu erhöhen und gleichzeitig eine einfache Konstruktion vorzustellen, wird vorgeschlagen, dass die Anordnung eine Kraftübertragungsstruktur (65; 165) umfasst, welche eine Kraft von einer Einleitungsstelle (56; 156) an wenigstens einen in der Flanschverbindung liegenden Wirkpunkt (59; 159) überträgt.

The invention relates to an arrangement with a vacuum pump (1; 100)) which has a pump flange (10; 110; 70), a chamber (2) which has a chamber flange (20; 120) with a flange connection for the vacuum - tight connection of Chamber and vacuum pump. In order to increase the mountability and at the same time to present a simple construction, it is proposed that the arrangement comprise a force transmission structure (65; 165) transmitting a force from an introduction point (56; 156) to at least one point of action (59; 159 ) transmits.
