Description

Die Erfindung betrifft einen-Kreiselverdichter mit mindestens vier hintereinandergeschalteten Stufen auf zwei oder mehr einander parallelen, mit von- , einander verschiedener Drehzahl laufenden Wellen, die von einem . gemeinsamen Zahnrad aus durch Ritzel angetrieben werden, wobei die beiden Laufräder jeder Welle beiderseits des Getriebes fliegend angeordnet sind und in Einzelgehäusen laufen, die am. Getriebegehäuse befestigt, insbesondere angeflanscht sind, nach Patent 974 418. -Erfindungsaufgabe ist, Luftkühler, Schmierölkühler und Schmiersammelbehälter so mit dem Verdichter zu vereinigen, daß dieser wenig Baustoff und wenig Platz erfordert und leicht verfrachtet und--fundamentiert werden kann, nämlich daß jene Teile nicht erst am Aufstellungsort, sondern schon in der Werkstatt mit dem Verdichter verbünden werden können und mit ihm ein starres Ganzes bilden.The invention relates to a centrifugal compressor with at least four stages connected in series to two or more parallel, with , mutually different speed running shafts that are driven by one. common Gear wheel is driven out by pinion, the two impellers of each shaft are cantilevered on both sides of the gearbox and run in individual housings, which are fastened, in particular flanged, to the transmission housing, according to patent 974 418. The task of the invention is to create an air cooler, lubricating oil cooler and lubricating container to be combined with the compressor in such a way that it requires little building material and little space and can easily be shipped and - grounded, namely that those parts are not connect with the compressor only at the installation site, but rather in the workshop can become and form a rigid whole with it.

Die Erfindung besteht in erster Linie darin, daß das Getriebegehäuse auf einer kastenartigen, den oder die Luftkühler enthaltenden Grundplatte ruht. Ferner kann die Grundplatte auch als Schmierölsammelbehälter ausgebildet sein; auch kann sie zugleich den oder die Schmierölkühler enthalten.The invention consists primarily in the fact that the gear housing rests on a box-like base plate containing the air cooler or coolers. Furthermore, the base plate can also be designed as a lubricating oil collecting container; even it can also contain the lubricating oil cooler (s).

In der Zeichnung ist ein Ausführungsbeispiel für die Erfindung dargestellt.In the drawing, an embodiment of the invention is shown.

Abb. i ist eine Seitenansicht, Abb. 2 eine Stirnansicht der Anlage.Fig. I is a side view, Fig. 2 is a front view of the plant.

Ein Elektromotor i treibt über eine Kupplung 2 ein Getriebe 3, an dessen beiden getriebenen Wellen vier Gebläsestufen 4 bis 7 angeordnet sind. Die Luft wird bei 8 angesaugt und gelangt durch einen Stutzen 9 in einen Zvrischenkübler io, der in einem kantenartig ausgebildeten Träger ii herausziehbar untergebracht ist. Aus diesem Zwischenkühler wird die Luft durch die nächste Stufe 5 angesaugt und weiter in einen Zwischenkühler 12 gedrückt. Von diesem gelangt sie in die Stufe 6 und aus dieser in einen Kühler 13. Die Stufe 7"_ saugt die Luft« aus dem letzten Zwischenkühler an und gibt sie in einen Druckstutzen 14. Das Tragorgan ii ist, wie bei 15 angedeutet, zugleich als Ölbehälter ausgebildet. Schließlich ist auch ein Ölkühler 16 herausnehmbar in diesem Tragorgan angeordnet.An electric motor i drives a transmission 3 via a clutch 2 the two driven shafts of which four fan stages 4 to 7 are arranged. the Air is sucked in at 8 and passes through a nozzle 9 into a Zvrischenkübler io, which is housed in an edge-like carrier ii so that it can be pulled out is. The air is sucked in from this intercooler through the next stage 5 and further pressed into an intercooler 12. From this she gets into the stage 6 and from this into a cooler 13. Stage 7 "_ sucks the air" out of the last Intercooler and puts it in a pressure port 14. The supporting element ii is how indicated at 15, at the same time designed as an oil container. Finally there is also a Oil cooler 16 is removably arranged in this support member.
