Description

Umlaufverdichter mit im Verdichtergehäuse befindlkhen, von der Kolbentrommelwelle aus angetriebenen StÜtzringen Bei Umlaufverdichtern hat nian zur Entlastung der Innenfläche des zylindrischen Gehäuses von der Massenwirk-ung der Schieberkolben und damit zur Verringerung der bekannten Riffelbildung auf dieser Fläche lose im- Gehäuse angeordnete, mitumlaLiifende Büchsen oder-auch neben den Lagerschilden befindliche Stützringe angebracht, die in den Gehauseinnenrauni hineinragen und die Schieberkolben abfangen.Recirculating compressor with located in the compressor housing, from the piston drum shaft from driven support rings In rotary compressors, nian has to relieve the Inner surface of the cylindrical housing from the mass effect of the spool piston and thus loosely im- Enclosed, mitumlaLiifende bushings or-also located next to the end shields Support rings attached that protrude into the housing interior and the slide piston intercept.

Nachdem ursprünglich diese Büchsen bzw. Stützringe durch die Schieberkolben mitgenommen wurden, ging man später dazu über, die Büchsen von der Kolbentrommel aus mittels Lenker, Zahnräder oder durch in der Trommel verschiebbare Schienen mitzunehmen.After originally these bushings or support rings through the slide piston were taken away, they later switched to removing the cans from the piston drum to take with you by means of handlebars, gears or rails that can be moved in the drum.

Bei den hcute gebriluchlichen.Schnelläufern aber ist die Verwendung von Büchsen, vor allem wegen der schlechten Wärmeableitung, untunlich. Ein bekannter Antrieb für Stützringe jedoch ist für hohe Drehzahlen wenig .geeignet; außerdem ist die seitliche Abd-ichtun- unvollkommen und die Herstellung schwierig. Ferner bech-ngt diese Ausführung eine geteilte Kolbentrommel.In the case of the most common high-speed runners, however, the use of cans, especially because of the poor heat dissipation, impractical. A friend Drive for support rings, however, is not very suitable for high speeds; aside from that the lateral sealing is imperfect and manufacture is difficult. Further This version has a split piston drum.

Bei dem Umlaufverdichter nach der Eifindun 'g kommen aus den obengenannten Gründen Stützringe zur Anwendung. Der Antrieb der Ringe ist verhältnismäßig einfach und für den praktischen Betrieb gut geeignet.In the case of the rotary compressor according to the Eifindun 'g , support rings are used for the reasons mentioned above. The drive of the rings is relatively simple and well suited for practical operation.

Der Antrieb der Stützringe erfolgt erfindungsgemäß noch unter Zwischenschaltung einer Übersetzupg, die den Stützringen eine ,#eiin-ere Drehgesch-,viiid#gl,-eit erteilt, als sie C l# der Kolbentrommel zuteil -wird. Die Herabsetzung der Drehzahl für die Stüt7ringe ermöglicht eine einfachere Schmierung und eine einfachere Lagerung derselben.The drive of the support rings is carried out according to the invention even the interposition of a Übersetzupg, a, # Eiin-ere Drehgesch-, VIIId # gl issued the support rings EIT as they -is C # l of the piston barrel given. The reduction in the speed for the support rings enables easier lubrication and simpler storage of the same.

. Auf der Zeichnung sind in den Abb. i und 2 in schematischer Darstellung zwei verschiedene Möglichkeiten für den Antrieb der Stützringe angedeutet. In beiden Fällen ist eine im Gehäuse gelagerte Welle i vorgesehen, auf der kleine Zahnräder 2 angeordnet sind, die in Verzahnung gen der Stützringc- 3 eingreifen. . In the drawing, two different possibilities for driving the support rings are indicated in FIGS. 1 and 2 in a schematic representation. In both cases there is a shaft i mounted in the housing, on which small gears 2 are arranged, which mesh with the teeth of the support ring 3 .

Im Falle der Ausführung nach Abb. i wird die Welle i von der Kolbentrommelwelle 4 aus durch Schneckenrad 5, Schnecke 6, Welle 7 und die Kegelräder8 und 9 angetrieben. ' Im Falle der Ausführung nach Abb. 2 wird von der Kolbentrommelwelle4 eine bekannte Zahnradflüssigkeitspumpe io angetrieben, welche Flüssigkeit unter Druck zu dem auf die Welle i wirkenden Flüssigkeitsmotor ii gelangen läßt, der die Welle i antreibt.In the case of the embodiment according to Fig. I, the shaft i is driven from the piston drum shaft 4 by worm wheel 5, worm 6, shaft 7 and the bevel gears 8 and 9. 'In the case of the embodiment according to Fig. 2 shows a known gear liquid pump is driven by the io Kolbentrommelwelle4, can ii get under pressure to the liquid acting on the shaft i engine which fluid, which drives the shaft i.
