Description
Die Erfindung betrifft eine Druckmittelzu. führung für solche Einrichtungen von Fahrzeugen, insbesondere Luftfahrzeugen, die mii dem Druckmittel, z. B. Drucköl, betrieben oder geschmiert werden sollen und die mit der Druckmittelquelle über in einer Schwingungen unterworfenen Welle vorgesehene Bohrungen verbunden sind, wie dies beispielsweise bei hydraulischen Verstelleinrichtungen für Verstelluftschrauben von Flugzeugen der Fall ist. Die Olzuführung für derartige Einrichtungen ist in besonders hohem Maße Wechselbeanspruchungen durch Schwingungen und damit verbundenen Abweichungen der Anschlußstellen von der axialer Richtung bzw. Bewegungen derselben in axialer Richtung ausgesetzt, welche durch die bekannten Ölzuführungen nicht ohne weiteres aufgenommen werden können.The invention relates to a pressure medium to. guidance for such facilities of vehicles, in particular aircraft, which mii the pressure medium, z. B. pressure oil, are to be operated or lubricated and which are connected to the pressure medium source via in a shaft subject to vibration provided bores are connected, such as this is the case, for example, with hydraulic adjustment devices for adjustment propellers of aircraft is the case. The oil supply for such facilities is in particularly high levels of alternating stresses caused by vibrations and the associated Deviations of the connection points from the axial direction or movements of the same exposed in the axial direction, which is not without the known oil supplies further can be included.
Die bekannten COlzuführungen sind zwar häufig elastisch ausgebildet. Sie haben jedoch den Nachteil, daß ihre Einmündungen in die mit der Verbraucherstelle in Verbindung stehende Leitung, z. B. in eine axial verlaufende Bohrung einer umlaufenden Welle, über Dichtungen erfolgt, welche bei den erwähnten Schwingungen zu Leckverlusten führen bzw. ihre Anschlüsse erfolgen derart, daß Bewegungen der Anschlußstellen in axialer Richtung und von der axialen Richtung abweichende Bewegungen, wie Versuche gezeigt haben, von ihnen nicht aufgenommen werden können, ohne daß außer Leckverlusten sogar häufig Brüche der Leitungen auftreten.The known oil feeds are often designed to be elastic. However, they have the disadvantage that their junctions with the consumer point related line, e.g. B. in an axially extending bore of a circumferential Shaft, takes place via seals, which in the case of the vibrations mentioned lead to leakage losses lead or their connections are made in such a way that movements of the connection points Movements deviating from the axial direction and from the axial direction, such as experiments have shown that they cannot be absorbed without any exceptions to leakage There are even frequent breaks in the lines.
Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß an einem die umlaufende Welle abdichtend umgebenden, aber frei einstellbaren Zuführungsring, der einen mit den Bohrungen der Welle verbundenen ringförmigen Hohlraum aufweist, mehrere bogenförmig ausgestaltete, in einer Aufhängung im Abstand vom Zuführungsring starr gelagerte Arme der Druckmittelzuführungsleitung angeschlossen sind, wobei die Anschlußstellen vorteilhaft in einer gemeinsamen Querebene gleichmäßig zueinander versetzt gewählt sind.According to the invention, these disadvantages are avoided in that on a freely adjustable feed ring surrounding the rotating shaft in a sealing manner, which has an annular cavity connected to the bores of the shaft, several arched, in a suspension at a distance from the feed ring rigidly mounted arms of the pressure medium supply line are connected, wherein the connection points advantageously evenly to one another in a common transverse plane are chosen offset.
In der Zeichnung ist ein Ausführungsbeispiel einer an die Welle einer hydraulisch verstellbaren Luftschraube angeschlossenen Druckmittelzuführung gemäß der Erfindung im Längsschnitt (Abb. i) und im Querschnitt (Abb.2) ersichtlich.In the drawing, an exemplary embodiment is one on the shaft hydraulically adjustable propeller connected pressure medium supply according to the invention in longitudinal section (Fig. i) and in cross section (Fig.2) can be seen.
Gemäß den Abb. i und 2 erfolgt die Druckmittelzuführung zu der Axialbohrung 8 einer umlaufenden Welle 5 von der Druckmittelquelle aus über zwei getrennte Rohrleitungen i und 2, die gemeinsam in einer Aufhängung 3 gelagert und unnachgiebig gehalten sind. Die Leitungsteile i und 2 sind bogenförmig gestaltet und mit ihren Enden an einen die Welle 5 umschließenden feststehenden Ring 4 vorzugsweise starr angeschlossen, derart, daß sie mit dem durch eine Ausdrehung 6 gebildeten Hohlraum dieses Ringes .t in Verbindung stehen. Der Ringhohlraum 6 steht seinerseits über die Querbohrung 7 der Welle mit der Längsbohrung 8 derselben in Verbindung. Um die Zuleitungsrohre vor zusätzlichen Beanspruchungen durch Reibungsmomente zu schützen, findet der Ring 4 mit einem Lappen 9 einseitig Anlage an einem festen Anschlag io. Auf diese Weise wird eine elastische Druckmittelzuführung erzielt, die gegen etwa auftretende Schwingungen unempfindlich ist, so daß Undichtigkeiten zuverlässig- vermieden sind, und die dem Zuführungsring die erforderliche Einstellfreiheit zur umschlossenen Welle ermöglicht.According to Figs. I and 2, the pressure medium is supplied to the axial bore 8 of a rotating shaft 5 from the pressure medium source via two separate pipes i and 2, which are stored together in a suspension 3 and held rigidly are. The line parts i and 2 are arcuate and have their ends on a fixed ring 4 surrounding the shaft 5, preferably rigidly connected, such that they with the cavity formed by a recess 6 of this ring .t connected. The annular cavity 6 in turn stands over the transverse bore 7 of the shaft with the longitudinal bore 8 of the same in connection. To the supply pipes The ring is designed to protect against additional stresses caused by frictional moments 4 with a rag 9 one-sided contact with a fixed stop io. In this way an elastic pressure medium supply is achieved that counteracts any vibrations that may occur is insensitive, so that leaks are reliably avoided, and the dem Feed ring allows the necessary freedom of adjustment to the enclosed shaft.
