Description

Olentschäumer für Brennkraftmaschinen, insbesondere Flugmotoren Es sind Ölentschäumer für Brennkraftmaschinen, insbesondere für Flugmotoren, bekannt, bei. denen das mit Luft vermischt aus dem Motor herauskommende Schmieröl in einer mit hoher Drehzahl umlaufenden Trommel geschleudert und darauf das entschäumte Öl in der Nähe des Umfanges, die ausgeschiedene Luft in der Nähe der Achse der Schleudertrommel aus dem Gehäuse des Entschäumers abgeleitet werden. Hierbei läßt es sich nicht vermeiden, daß sich auf der Innenfläche der Schleudertrommel auch feste Verunreinigungen des Schmieröls abscheiden, die sich mit der Zeit dort ansammeln, sio daß der Ölentschäumer in verhältnismäßig kurzen Zeitabschnitten immer wieder gereinigt werden muß, da schon seine Zweckbestimmung als Entschäumer eineAusführung der Sch,leudertrommel bedingt, die diese zur Aufspelicherung größerer Mengen von Verunreinigungen ungeeignet macht.Oil defoamers for internal combustion engines, in particular aircraft engines Es oil defoamers for internal combustion engines, especially for aircraft engines, are known, at. which the lubricating oil coming out of the engine mixed with air in one spun at high speed rotating drum and then the defoamed oil near the circumference, the excreted air near the axis of the centrifugal drum can be derived from the housing of the defoamer. Here it cannot be avoided that on the inner surface of the centrifugal drum also solid impurities of the Separate lubricating oil, which collects there over time, sio that the oil defoamer has to be cleaned again and again in relatively short periods of time, since its intended purpose as a defoamer is a version of the Sch, leudertrommel This makes them unsuitable for Aufspelicherung larger amounts of impurities power.

Um nun den Zei.tabstand, in dem jeweils eine Reinigung des gesamten Entschäumers notwendig wird, wesentlich zu verlängern, ist gemäß der Erfindung am Eintrittsende der Schleudertrommel des Entschäumers eine leicht abnehmbare Vorschleuder zum Zurückhalten fester Verunreinigungen angeordnet. Now to the time interval in which a cleaning of the entire Defoamer is necessary to extend significantly, is according to the invention on Entrance end of the centrifugal drum of the defoamer one easy detachable pre-centrifuge arranged to hold back solid impurities.

Dadurch wird erreicht, daß die sich in der Vorschleuder abscheidenden Verunreinigungen durch häufigere Reinigung der Vorschleuder auf einfache Weise entfernt werden können, ohne daß jedesmal der gesamte 01-entschäumer ab- oder ausgebaut werden muß.It is thereby achieved that the separating in the pre-centrifuge Contamination is easily removed by cleaning the pre-centrifuge more frequently without having to dismantle or dismantle the entire 01 defoamer each time got to.

Eine Vervollkommnung der Erfindung besteigt darin, daß die Vorschleuder gleichzeitig als eintrittsseitige Lagerung der Schleudertrommel des Entschäumers an dem abnehmbaren Gehäusedeckel des Entschäumers, ausgebildet und nur durch eine Steckverbindung mit der Schleudertrommel des Entschäumers verbunden ist, so daß heim Abnehmen des Gehäusedeckels gleichzeitig auch die Vorschleuder aus dem Gehäuse herausgezogen wird. Hierbei ist die Vorschleuder zweckmäßig als Ring von U-förmigem Querschnitt ausgebildet, der an seinem eintrittsseitigen Schenkel mit einem axial gerichteten Flansch zur Aufnahme des Dreh lagers versehen ist. A perfection of the invention is that the pre-centrifuge at the same time as the inlet-side storage of the centrifugal drum of the defoamer on the removable housing cover of the defoamer, formed and only by one Plug connection is connected to the centrifugal drum of the defoamer, so that When you remove the housing cover, you also remove the pre-centrifuge from the housing at the same time is pulled out. Here, the pre-centrifuge is useful as a U-shaped ring Cross-section formed on its inlet-side leg with an axial directed flange for receiving the rotary bearing is provided.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt. Es zeigt Abb. I einen Längsschnitt durch den Entschäumer und Abb. 2 einen Schnitt nach der Linie 2-2 der Abb. I. The invention is shown in the drawing in an exemplary embodiment. Fig. I shows a longitudinal section through the defoamer and Fig. 2 shows a section according to line 2-2 of Fig. I.

In dem Gehäuse 3 des Entschäumers ist die Schleudertrommel 4 angeordnet, die durch schaufelartige Stege 5 mit ihrer Welle 6 fest verbunden ist. Die Welle ist bei 7 in dem Gehäuse 3 drehbar gelagert und wird während des Betriebes der Brennkraftmaschine von dieser ständig mit hoher Drehzahl angetrieben. Das aus dem Ölsumpf der Brennkraftmaschine abgepumpte, stark mit Luft verschäumte Schmieröl gelangt durch den Eintrittsstutzen 8 in den Entschäumer und fließt dort auf dem durch die Pfeile g angedeuteten Wege in die Schleudertrommel 4 hinein, wo es durch die Schaufeln 5 gezwungen wird, an der schnellen Drehung der Trommel teilzunehmen. Dabei wird das Öl durch die Fliehkraft von der mitgeführten Luft getrennt. Das entschäumte Öl fließt durch den spiralförmig gekrümmten Kanal fo aus dem Gehäuse 3 ab, während die ausgeschiedene Luft den Entschäumer durch den Kanal 11 verläßt. Insoweit unterscheidet sich der beschriehene Entschäumer nicht von bekannten Vorrichtungen dieser Art. The centrifugal drum 4 is arranged in the housing 3 of the defoamer, which is firmly connected to its shaft 6 by shovel-like webs 5. The wave is rotatably mounted at 7 in the housing 3 and is during operation of the internal combustion engine driven by this constantly at high speed. That from the oil sump of the internal combustion engine Pumped-out lubricating oil, heavily foamed with air, passes through the inlet nozzle 8 into the defoamer and flows there on the path indicated by the arrows g into the centrifugal drum 4, where it is forced by the blades 5 to participate in the rapid rotation of the drum. Thereby the oil is caused by the centrifugal force separated from the entrained air. The defoamed oil flows through the spiral curved channel fo from the housing 3, while the excreted air the defoamer through the channel 11 leaves. The defoamer described differs in this respect not of known devices of this type.

Gemäß der Erfindung ist am Eintrittsende der Schleudertrommel 4 eine Vorschleuder in Gestalt eines einfachen Ringes 12 von im wesentlichen U-förmigem Querschnitt leicht abnehmbar angeordnet. Der Ring I2 ist einfach von der Eintrittsseite her in die Trommel 4 hineingesteckt und im übrigen so ausgebildet, daß er durch seine Schulter I3 genau mittig in der Trommel gehalten und durch die Schaufeln 5 der Trommel bei deren Drehung mitgenommen wird, indem die Schaufeln 5 in entsprechende Aussparungen eines ringförmigen Vorsprungs 14 des Ringes 12 eingreifen. According to the invention, at the inlet end of the centrifugal drum 4 is a Pre-slinger in the form of a simple ring 12 of essentially U-shaped Cross-section arranged to be easily removable. The ring I2 is easy from the entry side her inserted into the drum 4 and otherwise designed so that it through his shoulder I3 held exactly in the middle of the drum and through the blades 5 the drum is entrained in its rotation by the blades 5 in corresponding Recesses of an annular projection 14 of the ring 12 engage.

Der Ring 12 ist auf der Eintrittsseite außerdem mit einem axial gerichteten Ringflansch I5 versehen, mit dem er sich auf das Kugellager I6 stützt, das in ihm durch einen Sprengring 17 gegen Verschieben in axialer Richtung gesichert ist. Der Innenring des Kugellagers I6 wird durch die mit einem Bund 18 versehene Schraubhülse 19 und die Ringmutter 20 fest mit dem abnehmbaren Gchäusedeckel 21 verbunden, so daß beim Abnehmen des Deckels 21 nach Lösen der Halteschrauben 22 die Vorschleuder 12 mit herausgezogen wird und die sich während des Betriebes dort ansammelnden, aus dem Schmieröl au sgeschleuderten Ve!runreinigungen 23 mit Leichtigkeit entfernt werden können. The ring 12 is also on the entry side with an axially directed Annular flange I5 provided with which it rests on the ball bearing I6 that is in it is secured by a snap ring 17 against displacement in the axial direction. Of the The inner ring of the ball bearing I6 is secured by the screw sleeve provided with a collar 18 19 and the ring nut 20 firmly connected to the removable housing cover 21, see above that when you remove the cover 21 after loosening the retaining screws 22, the pre-centrifuge 12 is also pulled out and the accumulating there during operation, Impurities 23 thrown out of the lubricating oil are easily removed can be.

Das Abscheiden der Verunreinigungen in dem Ring 12 wird durch die an dem freien Ende der Welle 6 befestigte Schleuder- und Umlenkscheibe 24 bewirkt, die denn durch den Stutzen 8 eintretenden Schmieröl eine Drehbelwegung erteilt und es zwingt, in Richtung der Pfeileg durch die Vorschleuder zu fließen. The separation of the impurities in the ring 12 is through the causes centrifugal and deflection disk 24 attached to the free end of the shaft 6, because the lubricating oil entering through the nozzle 8 is given a rotary motion and it forces it to flow in the direction of the arrow through the pre-slinger.
