Description

Drebkolbenmaschine, insbesondere -pumpe. Den Gegenstand der Erfindung bildet eine Drehkolbenmaschine, insbesondere =pumpe, mit sichelförmigem Arbeitsraum und Schieberkolben, bei welcher zwischen diesen und dem Gehäuse eine mitumlaufende Hülse zur Aufnahme der Kolbenfliehkräfte eingeschaltet ist.Rotary piston machine, especially a pump. The subject of the invention forms a rotary piston machine, in particular a pump, with a sickle-shaped working space and slide piston, in which between these and the housing a rotating Sleeve to absorb the piston centrifugal forces is switched on.

Von den bekannten Ausführungen dieser Art unterscheidet sich der Erfindungsgegenstand dadurch, daß die Hülse mit der Kolbentrommel durch ein Zahnradgetriebe verbunden ist. Hierdurch wird zwangläufig die Hülse mit der gleichen Winkelgeschwindigkeit durch die Kolbentrommel gedreht.The subject matter of the invention differs from the known designs of this type in that the sleeve is connected to the piston drum by a gear train is. This inevitably causes the sleeve to travel at the same angular velocity rotated by the piston barrel.

In der Zeichnung sind zwei Ausführungsbeispiele schematisch dargestellt.Two exemplary embodiments are shown schematically in the drawing.

Abb. i ist ein Querschnitt nach Linie II-II der Abb. 2, Abb. 2 ein Schnitt nach Linie III-III der Abb. i, Abb. 3 ein Schnitt nach Linie IV-IV der Abb. 2, Abb. q. ein der Abb. 3 entsprechender Schnitt durch eine andere Ausführung des Getriebes; Abb.5 und 6 sind Darstellungen der Kolben.Fig. I is a cross-section along line II-II of Fig. 2, Fig. 2 a Section along line III-III in Fig. I, Fig. 3 a section along line IV-IV in Fig. 2, fig.q. a section corresponding to Fig. 3 through another embodiment of the Transmission; Figures 5 and 6 are representations of the pistons.

Die Kolbentrommel i (Abb. i, 2 und 5) wird von einer Hülse 2 umschlossen, die in Kugellagern 3 3' läuft. Die Kolben 4 sind in den Radialnuten 5 der Kolbentrommel geführt.The piston drum i (Fig. I, 2 and 5) is enclosed by a sleeve 2, which runs in ball bearings 3 3 '. The pistons 4 are in the radial grooves 5 of the piston drum guided.

Die Hülse :2 (Abb. 2) wird an den Enden durch die Hohlzapfens, 5' getragen, auf denen die Kugellager 3, 3' angebracht sind. Durch diese Zapfen gehen die Achsen der Trommel, die in den Kugellagern 7, 7' laufen.The sleeve: 2 (Fig. 2) is inserted at the ends through the hollow pin, 5 ' worn on which the ball bearings 3, 3 'are attached. Go through these tenons the axes of the drum, which run in the ball bearings 7, 7 '.

Der Hohlzapfen 5' hat außen eine Verzahnung 8, und auf der Achse 6' ist ein Zahnrad 9 von gleichem Durchmesser und Teilung wie das Rad 8 aufgekeilt. Die Räder 8 und 9 greifen in einen Innenzahnkranz io, der auf den Kugellagern i i, i i' läuft. Das Ganze bildet ein Getriebe, durch das die Hülse :2 von der Trommel i mit gleicher Geschwindigkeit und in gleichem Drehsinn mitgenommen wird.The hollow pin 5 'has a toothing 8 on the outside, and on the axis 6' a gear wheel 9 of the same diameter and pitch as the wheel 8 is keyed. The wheels 8 and 9 engage in an internal ring gear io, which is on the ball bearings i i, i i 'is running. The whole forms a gear through which the sleeve: 2 from the drum i is taken along at the same speed and in the same direction of rotation.

Bei der Ausführung der Abb. q. greifen die Räder 8' und 9' in ein Zwischenrad 12, das umgekehrt läuft.When performing fig. Q. the wheels 8 'and 9' mesh Intermediate gear 12 that runs in reverse.

Die Hülse 2 (Abb. i und 2) hat Ein- und Auslaßöffnungen. Bei der Drehung der Hülse treten diese öffnungen im geeigneten Zeitpunkt mit der Saugleitung-und Druckleitung in Verbindung.The sleeve 2 (Fig. I and 2) has inlet and outlet openings. When turning These openings enter the sleeve at the appropriate time with the suction line and Pressure line in connection.

Bei geringen Geschwindigkeiten, bei denen die Fliehkraft nicht ausreicht, um die Kolben dicht genug gegen die Hülse anzudrücken, sind Federn zwischen die Bunde 1q., 1q.' der Hohlzapfen 5, 5' und die Kolben eingeschaltet.At low speeds where the centrifugal force is insufficient, in order to press the pistons tight enough against the sleeve, there are springs between the Bundles 1q., 1q. ' the hollow pin 5, 5 'and the piston switched on.

Diese Federung der Kolben q. wird auf einfache Art bewirkt, indem der innere Rand der Kolben auf einer gewissen Länge geschlitzt wird, so daß Zungen 13 (Abb. 5 und 6) entstehen, welche federn.This suspension of the piston q. is effected in a simple way by the inner edge of the piston is slotted over a certain length, so that tongues 13 (Fig. 5 and 6) arise, which are feathers.
