Description

Die Erfindung bezieht sich auf eine Lagerung von vorzugsweise durch mehrere Motoren angetriebenen Luftschraubenwellen, die an einem Ende der Triebwerkswelle schwenkbar gekuppelt und an ihrem enderen Ende in einem festen Teil elastisch abgestützt ist.The invention relates to a storage of preferably by multiple motors driven propeller shafts attached to one end of the propeller shaft pivotally coupled and elastically supported at its end in a fixed part is.

Insbesondere bezieht sich die Erfindung auf eine weitere Verbesserung und Ausgestaltung eines Luftschraubenantriebes nach Patent &77109, bei welchem das vordere Ende der Luftschraubenwelle mittels eines Schulterlagers zur Aufnahme von Schubkräften in einem die Welle umgebenden Schubrohr gelagert ist, dessen vorderes Ende elastisch in einem am Flugzeug festen Teil und dessen hinteres Ende schwenkbar, aber axdal umverschiebl,ich am Triebwerksgehäuse aufgehängt ist.In particular, the invention relates to a further improvement and design of a propeller drive according to patent & 77109, in which the front end of the propeller shaft by means of a shoulder bearing for receiving is mounted by thrust forces in a thrust tube surrounding the shaft, the front of which The end is elastic in a part fixed to the aircraft and its rear end can be pivoted, but axdal umverschiebl, I is suspended from the engine housing.

Die Erfindung besteht darin, .daß eine Luftschraub:enwelle in an sich bekannter Weise in: einer Hohlwelle angeordnet ist, die, für sich angeordnet wiederum die, Antriebswelle für eine zweite Luftschraube bildet und beide Hohlwellen an einem Ende, nahe ihrem Antrieb, praktisch um den gleichen Punkt schwenkbar gelagert und am anderen. Ende zusammen an einem festen Bauteil des Luftfahrzeuges elastisch abgestützt sind. Als Gelenkverbindung dienen für beide Luftschrauben, wehren elastische Kupplungen. Die äußere Luftschraubenwelle wird außerdem durch in .deren: Antrieb eingeschaltete Zwischenräder gegenüber der inneren Luftscbraubenwelle in einem gegenläufigen Drehsinn angetrieben.The invention consists in .that a propeller shaft in itself known way in: a hollow shaft is arranged, which, in turn, arranged for itself which forms the drive shaft for a second propeller and both hollow shafts on one End, near their drive, mounted and pivoted practically about the same point at the other. End together elastically supported on a fixed component of the aircraft are. Both propellers are used as an articulated joint, and flexible couplings defend themselves. The outer propeller shaft is also switched on by its drive Intermediate gears opposite the inner propeller shaft in an opposite direction of rotation driven.

Die Vorteile, die durch die schwenkbare und Elastische Lagerung sowie durch die Anordnung eines Schubrohres erreicht werden, wurden in dem Patent 877 log eingehend dargelegt und begründet: Die Anordnung der Motorenzylinder auf einem gemeinsamen Kurbelgehäuse bietet dem Vorteil gedrängter Bauweise und einfacher Lagerung der vor den Motoren angeordneten Triebwerksteile zum Antrieb der gegenläufigen Luftschraubenwellen. Außerdem werden gefährliche Verschiebungen der beiden Hauptantriebswellen zueinander vermieden, und .die Aufhängung der Antriebsaggregate im Flugzeug gestaltet sich außerordentlich einfach.The advantages of the swiveling and elastic mounting as well can be achieved by the arrangement of a thrust tube, were in the patent 877 log explained in detail and justified: The arrangement of the engine cylinders on a common crankcase offers the advantage of compact design and simple storage the engine parts arranged in front of the engines to drive the propeller shafts rotating in opposite directions. In addition, there are dangerous displacements between the two main drive shafts avoided, and .the suspension of the drive units in the aircraft is designed extremely easy.

In der Zeichnung ist .ein Ausführungsibeisp.iel der `Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.

D:ie Zylinder der beiden Brennkraftmaschinen. i und 2 sind auf dem gemeinsamen Kurbelgehäuse 3 im Winkel zueinander geneigt angeordnet. Die beiden. nach außen verlängerten Kurbelwellen tragen die Überholungskupplungen 6, 7 sowie die Stirnräder 8, 9 bzw. io, i i. Die Stirnräder 8, io greifen in das zentral angeordnete Stirnrad 12 ein, das mit der Wellet 13 verbunden ist. Die innere Luftschraubenwelle 14 ist mit der Welle 13 durch die elastische Kupplung 15 verbunden. Die beiden Stirnräder 9, 11 treiben über Zwischenräder 18, ig das zentral angeordnete Strirnrad2i der äußerem. gegenläufigen Luftschraubenwelle 17 an. Diese We lei 17 iist wiederum durch !die elastische Kupplung 22 mit dem zentral angeordneten und mit dem Stirnrad 2.1 verbundenen Wellenstück 23 gekuppelt. Das Schubrohr 24, welches in der Länge z. B. durch einen Stellring 2,o einstellbar ist; ruht in einem Gelenklager 2q.' .des. Getriebegehäusedeckels. Die elastische Lagerung,des Schubrohres 24 erfolgt an den Stellen 25 und 26 z. B.. durch Gummiringe.The cylinders of the two internal combustion engines. i and 2 are on the common crankcase 3 arranged inclined at an angle to one another. The two. outwardly extended crankshafts carry the overhaul clutches 6, 7 as well the spur gears 8, 9 or io, i i. The spur gears 8, io engage in the centrally arranged A spur gear 12 which is connected to the shaft 13. The inner propeller shaft 14 is connected to the shaft 13 through the elastic coupling 15. The two spur gears 9, 11 drive the centrally arranged Strirnrad2i of the intermediate gears 18, ig external. opposing propeller shaft 17. This route 17 is again through The elastic coupling 22 with the centrally arranged and with the spur gear 2.1 connected shaft piece 23 coupled. The thrust tube 24, which z. B. by an adjusting ring 2, o is adjustable; rests in a spherical bearing 2q. ' .of. Gear housing cover. The elastic storage of the thrust tube 24 takes place on the Positions 25 and 26 e.g. B. by rubber rings.

Die Wirkungsweise dieser Anordnung ist im, übrigem, die gleiche, wie in dem Patent 8771o9 beschrieben. Die Anordnung kann auch so getroffen werden, daß nur gegenläufige Luftschraubenwellen vorhanden. sind und .die Antriebsmotoren getrennte Kurbelgehäuse. besitzen oder daß bei einem für alle Motoren. gemeinsamen Kurbelgehäuse nur eine Luftschrawbenwelle: vorhanden ist.The mode of operation of this arrangement is, for the rest, the same as described in patent 877109. The arrangement can also be made so that only opposing propeller shafts available. and .the drive motors are separate Crankcase. own or that with one for all engines. common crankcase only a Luftschrawbenwelle: is present.
