Die Dokumente JP 2003-129 966 A und JP 11-210 642 A beschreiben axiale Durchströmungen von Pumpenaggregaten ausschließlich innerhalb des Elektromotors beziehungsweise des Elektromotorstators.The Documents JP 2003-129 966 A and JP 11-210 642 A describe axial Flows through Pump units exclusively within the electric motor or the electric motor stator.
Aggregate dieser Bauart haben den großen Vorteil, dass sie nur einen minimalen Raum beanspruchen. Sie sind aber noch verbesserungsfähig.Aggregate of this type have the great advantage that they occupy only a minimal space. But they are still improvement.
Der Erfindung liegt die Aufgabe zugrunde, ein Motorpumpenaggregat der genannten Bauart noch weiter zu verbessern, insbesondere bezüglich des Fertigungsaufwandes und des Raumbedarfs.Of the Invention is based on the object, a motor pump unit of mentioned type to improve even further, in particular with respect to Manufacturing effort and space requirements.
Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.These The object is solved by the features of claim 1.
Die Erfindung geht somit von einem Motorpumpenaggregat aus, umfassend einen Elektromotor mit Stator und Rotor, eine Innenzahnradpumpe, die ein Hohlrad und ein Ritzel aufweist, sowie ein Gehäuse.The Invention thus starts from a motor pump unit, comprising an electric motor with stator and rotor, an internal gear pump, the a ring gear and a pinion, and a housing.
Entscheidende
Merkmale der Erfindung sind die folgenden:
Die genannten Bauteile
sind, radial von außen
nach innen gesehen, in der folgenden Reihenfolge angeordnet:
Stator
Rotor
Hohlrad
Ritzel.Crucial features of the invention are the following:
The components mentioned are arranged, viewed radially from outside to inside, in the following order:
stator
rotor
ring gear
Pinion.
Ganz wichtig ist, dass Rotor und Hohlrad unmittelbar drehfest miteinander verbunden sind. Es ist somit kein Übertragungsmittel vorgesehen. Die innere Mantelfläche des Rotors umschließt die äußere Mantelfläche des Hohlrades. Die beiden Flächen liegen eng aneinander an, so dass eine Drehmomentübertragung vom Rotor zum Hohlrad erfolgt. Dabei könnte eine Lage aus einem anderen Material noch zwischengefügt sein, beispielsweise aus einem isolierenden Material. Die drehfeste Verbindung kann durch mechanische Mittel hergestellt sein, aber auch beispielsweise durch Aufschrumpfen des Stators auf das Hohlrad.All It is important that the rotor and ring gear are directly against rotation with each other are connected. Thus, no transmission means is provided. The inner lateral surface encloses the rotor the outer surface of the Ring gear. The two surfaces lie close together, allowing a torque transfer from the rotor to the ring gear. This could be a situation from another Material still interposed be, for example, of an insulating material. The non-rotatable Connection can be made by mechanical means, but also, for example, by shrinking the stator to the ring gear.
Der Antrieb der Pumpe erfolgt somit nicht – wie üblich – über die Ritzelwelle, sondern über das Hohlrad. Hierdurch ist die Drehzahl des Ritzels um das Verhältnis der Anzahl der Zähne des Hohlrades zur Anzahl der Zähne des Ritzels größer.Of the Drive of the pump is thus not - as usual - on the pinion shaft, but on the ring gear. As a result, the speed of the pinion to the ratio of number of teeth of the ring gear to the number of teeth of the pinion larger.
Die aus Rotor und Hohlrad bestehende Einheit ist im Gehäuse gelagert, und zwar in Flanschen, die Bestandteile der Gehäusedeckel sind – entweder diesen angeformt, oder einteilig mit diesen. Dabei kann entweder das Hohlrad oder der Rotor gelagert sein – je nachdem, welches dieser beiden Bauteile länger ist.The consisting of rotor and ring gear unit is mounted in the housing, in flanges, which are components of the housing cover - either this molded, or in one piece with these. It can either the ring gear or the rotor be stored - ever after which of these two components is longer.
Die Lagerung des Ritzels ist ebenfalls in die genannten seitlichen Flansche integriert. Aufgrund dieser Bauweise läuft das Hohlrad im Zentrum des Motors um, während das Ritzel zum Erzielen der notwendigen Exzentrizität außermittig angeordnet ist.The Storage of the pinion is also in the said lateral flanges integrated. Due to this design, the ring gear runs in the center the engine around while the pinion eccentrically to achieve the necessary eccentricity is arranged.
Der Volumenstrom des zu fordernden und zu verdichtenden Mediums verläuft zur Saugseite und durch den Motor, wobei dieser gekühlt wird. Er strömt schließlich an der Druckseite aus. Damit lässt sich das Bauvolumen stark reduzieren.Of the Volume flow of the demanding and to be compressed medium runs to Suction side and by the engine, which is cooled. He finally flows the print side off. Leave it the construction volume is greatly reduced.
Die Erfindung ist anhand der Zeichnung näher erläutert. Darin sind zwei Ausführungsformen dargestellt, eine erste mit einer Innenzahnradpumpe großer axialer Baulänge, und eine zweite mit einer Innenzahnradpumpe mit geringer axialer Baulänge.The The invention is explained in more detail with reference to the drawing. This shows two embodiments, a first with an internal gear pump large axial length, and a second with an internal gear pump with a small axial length.

Im Folgenden sollen nochmals wesentliche Merkmale und Vorteile der Erfindung herausgestellt werden:
- – Bei dem erfindungsgemäßen Motorpumpenaggregat ist das aktive Bauteil, nämlich das Verdrängerelement Hohlrad mit dem Rotor drehfest verbunden. Es findet somit keine Einleitung von Drehmoment auf die Verdrängerelemente mittels eines Zahnringes oder eines Führungsringes statt. Die Drehmomentübertragung bedarf somit keiner zwischengeschalteten Bauteile.
- – Das Medium fließt durch den gesamten Motor und kühlt diesen. Die Stromführung ist optimal. Der gesamte Motor-Innenraum wird durchströmt.
- – Die integrierte Pumpe besteht allein aus der umlaufenden Einheit, umfassend Hohlrad und Ritzel.
- - In the motor pump unit according to the invention, the active component, namely the displacer ring gear rotatably connected to the rotor. There is thus no introduction of torque on the displacement elements by means of a toothed ring or a guide ring instead. The torque transmission thus requires no intermediate components.
- - The medium flows through the entire motor and cools it. The power supply is optimal. The entire engine compartment is flowed through.
- - The integrated pump consists solely of the rotating unit, comprising ring gear and pinion.
Es versteht sich, dass jegliches Medium in Betracht kommt, somit ein flüssiges Medium wie Öl oder Wasser und ein gasförmiges Medium wie Luft oder ein anderes Gas.It understands that any medium comes into consideration, thus one liquid Medium like oil or Water and a gaseous Medium like air or another gas.
