Abstract

The power transmission system has a planetary gear drive and a turbine rotor. One end (17) of the turbine rotor (18) is supported by the sun wheel shaft (16) of the planetary gear drive. The other end (20) of the turbine rotor (18) is supported by the extension (22) of the housing (13) of the planetary gear drive (10). The sun wheel of a planetary gear drive has no drive reaction and it can be used to support one end of the rotor. The reaction is transmitted to the internally toothed gear of the planetary gear drive whose mounting supports the other end of rotor. Axial reactions are compensated by herring bone gear teeth.

Description

Anordnung zur Kraftübertragung Arrangement for power transmission

Die Erfindung betrifft eine Anordnung zur Kraftübertragung gemäß dem Oberbegriff des Anspruches 1.The invention relates to an arrangement for power transmission according to the Preamble of claim 1.

Kleinere Turbinenrotoren in Kombination mit Parallelgetrieben werden oft mit einem überhängenden Teil versehen, um die Kupplungsanordnung zu umgehen, die sonst erforderlich wäre, um die Aufnahme der Getriebereaktion durch den Rotor zu vermeiden oder um eine Aufhängung von Rotor und Getriebe in drei Punkten zu vermeiden.Smaller turbine rotors can be combined with parallel drives often provided with an overhanging part to bypass the coupling arrangement, which would otherwise be required to take up the gear reaction through the rotor to avoid or to avoid suspension of the rotor and gearbox in three points.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anordnung zur Kraftübertragung der oben genannten Art zu entwickeln, bei der auf die genannte Kupplungsanordnung völlig verzichtet werden kann, ohne daß hierdurch die genannten Nachteile entstehen.The present invention is based on the object of an arrangement to develop power transmission of the type mentioned above, in the case of the said Coupling arrangement can be dispensed with entirely without the aforementioned Disadvantages arise.

Zur Lösung dieser Aufgabe wird eine Anordnung zur Kraftübertragung nach dem Oberbegriff des Patentanspruches vorgeschlagen, die erfindungsgemäß die im kennzeichnenden Teil des Anspruches genannten Merkmale hat.An arrangement for power transmission is used to solve this problem proposed according to the preamble of claim that according to the invention the has features mentioned in the characterizing part of the claim.

Das Sonncnrad eines Planetengetriebes hat keine Antriebsreaktion und kann mit Vorteil das eine Rotorende tragen. Die Reaktion wird dabei auf den Innenzahnkranz des Planetengetriebes übertragen, dessen Befestigung wiederum das andere Rotorende stützt. Axiale Reaxtionen werden über eine doppelte Schrägverzahnung im Getriebe ausgeglichen. Man erhält somit ein integriertes Turbinengetriebesystem, bei dem die Drehzahlentnabme nicht durch erforderliche Aufhängungspunkte begrenzt wird.The sun wheel of a planetary gear has no drive reaction and can advantageously carry one end of the rotor. The reaction is on the internal gear of the planetary gear, its fastening in turn the other end of the rotor supports. Axial extensions are made via a double helical toothing in the gearbox balanced. An integrated turbine transmission system is thus obtained in which the speed deviation is not limited by the required suspension points.

Anhand des in der Figur gezeigten Ausführungsbeispieles soll die Anordnung nach der Erfindung näher erläutert werden.Based on the embodiment shown in the figure, the arrangement should are explained in more detail according to the invention.

Ein Planetengetriebe 10 mit Planetenradträger 11, Hohlrad 12 mit Innenzahnkränzen sowie Sonnenrad (letzteres ist durch das Hohlrad 12 verdeckt und daher nur gestrichelt angedeutet) sind in einem Befestigungsgehäuse 13 angeordnet, welches im Schnitt gezeigt ist.A planetary gear 10 with planetary gear carrier 11, ring gear 12 with internal gear rings as well as sun gear (the latter is covered by the ring gear 12 and therefore only dashed indicated) are arranged in a mounting housing 13, which in section is shown.

Der Planetenradträger 11 ist an eine Welle 14 angeschlossen, die in einer Durchführung 15 im Gehäuse 13 angeordnet und gelagert ist und an eine äußere Einheit angeschlossen werden kann.The planet carrier 11 is connected to a shaft 14 which is shown in a bushing 15 is arranged and supported in the housing 13 and to an outer one Unit can be connected.

An die Welle 16 des Sonnenrades ist das eine Ende 17 eines Turbinenrotors 18 über eine Durchführung 19 im Gehäuse 13 momentenstarr angeschlossen, wobei die Durchführung mit einer Öldichtung versehen ist.One end 17 of a turbine rotor is attached to the shaft 16 of the sun gear 18 connected in a torque-proof manner via a bushing 19 in the housing 13, the Implementation is provided with an oil seal.

Das andere Ende 20 des Turbinenrotors 18 ruht in einem Lager 21, das von einem Ausläufer 22 des Gehäuses 13 getragen wird. Der Turbinenrotor 18 rotiert in einem Turbinengehäuse 23.The other end 20 of the turbine rotor 18 rests in a bearing 21, the is carried by an extension 22 of the housing 13. The turbine rotor 18 rotates in a turbine housing 23.

Das gezeigte System kann ür unterschiedlich große Turbinengetriebeausführungen verwendet werden. Es ist nicht auf die gezeigte Ausführungsform beschränkt, sondern kann im Rahmen des allgemeinen Erfindungsgedankens in verschiedener Weise variiert werden.The system shown can be used for turbine gear designs of different sizes be used. It is not limited to the embodiment shown, but rather can be varied in various ways within the scope of the general inventive concept will.
