- the design of the positive guide as a guide ring has the significant advantage that the working chambers of the vane pump are always axially accessible and are not closed by control or guide elements. To have to So no special breakthroughs are provided in components that would also hinder or interfere with the flow of the working fluid.
- the guide ring has a substantially C-shaped, ie laterally open cross-section with two free legs and a recess extending in the circumferential direction, in particular annular groove.
- Such a guide ring can be easily manufactured and is easy to install because it has no undercuts and because the ring is the same for both the front and the back, that is, the same for both faces of the pump.
- the stator and the sliding shoes can be recorded without play.
- the two free legs of the guide ring show axially inwards.
- the guide ring has a flat, forming the base of the ring outside, for example, rests on a closure cap.
- the two free legs of the guide ring surround the end face of the stator and thus define the position of the ring relative to the stator and thus within the vane pump. In this way, the stator is fixed in the pump.
- one of the two free limbs of the guide ring engages in an end recess of the sliding shoes.
- the frontal depression is a part-annular groove.
- the guide ring is mounted on the front side of the stator and the sliding shoes.
- This embodiment allows for easy assembly by only the guide ring must be axially attached to the axial end faces of the shoes.
- the sliding blocks can be held, for example by means of a special mounting tool in abutment against the inner peripheral surface of the stator until the guide ring is positioned.
- the cross-section of the end portion of the shoe is C-shaped, that is, laterally open, and the recess is flanked by two axially outwardly projecting legs.
- the guide ring and the shoes are therefore both C-shaped and engage with each other by interlocking, by the two sides facing the grooves are facing each other.
- the radially inner leg of the sliding shoe abuts the radial inner peripheral surface of the guide ring.
- an additional guidance is achieved, so that not only is it ensured that the sliding shoe does not lift off from the inner peripheral surface of the stator, but also that at high speeds, part of the contact pressure of the sliding shoe is absorbed by the guide ring.
- a particularly preferred embodiment provides that the axial end face of the radially inner leg of the sliding block and the axially outer end face of the guide ring lie in the same plane.
- the axially outer end face of the guide ring and the axial end faces of the wings in the same plane. This creates the possibility that each working space can be closed in a simple manner by a flat surface of a lid which bears against the two axial end faces of the sliding shoe and the guide ring.

Description
Die Erfindung betrifft eine Flügelzellenpumpe bestehend aus einem Außenrotor, einem Innenrotor und einer Vielzahl von Flügeln, die in im Wesentlichen radialen Schlitzen im Innenrotor radial verschieblich gelagert und am Außenrotor schwenkbar befestigt sind, wobei der Außenrotor von Gleitschuhen gebildet wird, wobei die Gleitschuhe an der Innenumfangsfläche eines Stators entlang gleiten und mit ihren axialen Stirnseiten in einer Führungsbahn geführt sind.The invention relates to a vane pump consisting of an outer rotor, an inner rotor and a plurality of vanes, which are mounted radially displaceably in substantially radial slots in the inner rotor and pivotally mounted on the outer rotor, wherein the outer rotor is formed by sliding shoes, wherein the sliding shoes on the inner peripheral surface slide along a stator and are guided with their axial end faces in a guideway.

Aufgabe der vorliegenden Erfindung ist es, eine Flügelzellenpumpe zu schaffen, die einen hohen Wirkungsgrad aufweist und gleichzeitig einfach und preiswert hergestellt und montiert werden kann.Object of the present invention is to provide a vane pump, which has a high efficiency and at the same time can be easily and inexpensively manufactured and assembled.
Diese Aufgabe wird erfindungsgemäß durch die Merkmalskombination von Anspruch 1 gelöst.This object is achieved by the feature combination of claim 1.
Die erfindungsgemäße Ausgestaltung der Flügelzellenpumpe mit einem eine Führungsbahn aufweisenden Führungsring besitzt den wesentlichen Vorteil, dass die Flügelzellenpumpe wesentlich einfacher aufgebaut ist, da sie zum einen aus weniger Bauteilen besteht, zum anderen die Bauteile einfacher gestaltet sind. Daher ist sie auch wesentlich einfacher montierbar. Der Führungsring dient zur Führung der Gleitschuhe, so dass diese stets, d.h. in jeder Betriebssituation der Flügelzellenpumpe an der Innenumfangsfläche des Stators anliegen und zwar auch unabhängig von der Drehzahl der Flügelzellenpumpe. Die Führungsbahn ist demnach eine Zwangführung für die Gleitschuhe, die deren permanente und fluiddichte Anlage an der Innenumfangsfläche gewährleistet.The inventive design of the vane pump with a guideway having guide ring has the significant advantage that the vane pump is much simpler, since it consists on the one hand of fewer components, on the other hand, the components are designed simpler. Therefore, it is also much easier to install. The guide ring serves to guide the sliding shoes so that they are always, i. abut in any operating situation of the vane pump on the inner peripheral surface of the stator and even regardless of the speed of the vane pump. The guideway is therefore a forced guide for the sliding blocks, which ensures their permanent and fluid-tight contact with the inner circumferential surface.
Die Ausgestaltung der Zwangsführung als Führungsring besitzt den wesentlichen Vorteil, dass die Arbeitskammern der Flügelzellenpumpe stets axial zugänglich sind und nicht von Steuer- oder Führungselementen verschlossen werden. Es müssen also keine speziellen Durchbrüche in Bauteilen vorgesehen werden, die zudem die Strömung des Arbeitsfluids behindern oder stören würden.The design of the positive guide as a guide ring has the significant advantage that the working chambers of the vane pump are always axially accessible and are not closed by control or guide elements. To have to So no special breakthroughs are provided in components that would also hinder or interfere with the flow of the working fluid.
Erfindungsgemäß weist der Führungsring einen im Wesentlichen C-förmigen, das heißt seitlich offenen Querschnitt mit zwei freien Schenkeln und einer in Umfangsrichtung verlaufenden Vertiefung, insbesondere Ringnut, auf. Ein solcher Führungsring kann einfach hergestellt werden und ist leicht montierbar, da er keine Hinterschneidungen besitzt und da der Ring sowohl für die Vorderseite als auch für die Rückseite, das heißt für beide Stirnflächen der Pumpe gleich ausgebildet ist.According to the invention, the guide ring has a substantially C-shaped, ie laterally open cross-section with two free legs and a recess extending in the circumferential direction, in particular annular groove. Such a guide ring can be easily manufactured and is easy to install because it has no undercuts and because the ring is the same for both the front and the back, that is, the same for both faces of the pump.
Durch eine exakte Bearbeitung der Nut können der Stator und die Gleitschuhe spielfrei aufgenommen werden. Dabei zeigen die beiden freien Schenkel des Führungsrings axial nach innen. Der Führungsring besitzt eine flache, die Basis des Rings bildende Außenseite, die zum Beispiel an einem Verschlussdeckel anliegt.By an exact machining of the groove, the stator and the sliding shoes can be recorded without play. The two free legs of the guide ring show axially inwards. The guide ring has a flat, forming the base of the ring outside, for example, rests on a closure cap.
Die beiden freien Schenkel des Führungsrings umgreifen die Stirnseite des Stators und definieren damit die Lage des Rings bezüglich des Stators und somit innerhalb der Flügelzellenpumpe. Auf diese Weise wird auch der Stator in der Pumpe fixiert.The two free legs of the guide ring surround the end face of the stator and thus define the position of the ring relative to the stator and thus within the vane pump. In this way, the stator is fixed in the pump.
Erfindungsgemäß greift einer der beiden freien Schenkel des Führungsrings, insbesondere der radial innere Schenkel, in eine stirnseitige Vertiefung der Gleitschuhe. Dabei ist die stirnseitige Vertiefung eine in teilringförmige Nut. Dieser Eingriff des freien Schenkels des Führungsrings in die Nut des Gleitschuhs bildet eine Verzahnung und gewährleistet die sichere Anlage des Gleitschuhs an der Innenumfangsfläche des Stators, auch wenn in den Arbeitsräumen zum Beispiel während des Ansaugtaktes ein Unterdruck herrscht.According to the invention, one of the two free limbs of the guide ring, in particular the radially inner limb, engages in an end recess of the sliding shoes. In this case, the frontal depression is a part-annular groove. This engagement of the free leg of the guide ring in the groove of the shoe forms a toothing and ensures the safe investment of the shoe on the inner peripheral surface of the stator, even if there is a negative pressure in the work spaces, for example during the intake stroke.
Bei einer Weiterbildung der Erfindung ist vorgesehen, dass der Führungsring stirnseitig auf den Stator und die Gleitschuhe aufgesetzt ist. Diese Ausgestaltung ermöglicht eine leichte Montage, indem lediglich der Führungsring axial auf die axialen Stirnseiten der Gleitschuhe aufgesteckt werden muss. Dabei können die Gleitschuhe zum Beispiel mittels eines speziellen Montagewerkzeugs in Anlage an die Innenumfangsfläche des Stators gehalten werden, bis der Führungsring positioniert ist.In a further development of the invention, it is provided that the guide ring is mounted on the front side of the stator and the sliding shoes. This embodiment allows for easy assembly by only the guide ring must be axially attached to the axial end faces of the shoes. In this case, the sliding blocks can be held, for example by means of a special mounting tool in abutment against the inner peripheral surface of the stator until the guide ring is positioned.
Bei einem bevorzugten Ausführungsbeispiel ist der Querschnitt des stirnseitigen Bereichs des Gleitschuhs C-förmig, das heißt seitlich offen, und die Vertiefung ist von zwei axial nach außen abragenden Schenkeln flankiert. Der Führungsring und die Gleitschuhe sind demnach beide C-förmig ausgebildet und greifen verzahnend ineinander, indem die beiden die Nuten aufweisenden Seiten einander zugewandt sind.In a preferred embodiment, the cross-section of the end portion of the shoe is C-shaped, that is, laterally open, and the recess is flanked by two axially outwardly projecting legs. The guide ring and the shoes are therefore both C-shaped and engage with each other by interlocking, by the two sides facing the grooves are facing each other.
Mit Vorzug liegt der radial innere Schenkel des Gleitschuhs an der radialen Innenumfangsfläche des Führungsrings an. Hierdurch wird eine zusätzliche Führung erreicht, so dass nicht nur gewährleistet ist, dass der Gleitschuh nicht von der Innenumfangsfläche des Stators abhebt, sondern auch dass bei hohen Geschwindigkeiten ein Teil der Anpresskraft des Gleitschuhs vom Führungsring aufgefangen wird. Außerdem wird durch diese Ausgestaltung des Gleitschuhs und des Führungsrings der Gleitschuh bei der Verstellung der Flügelzellenpumpe in Richtung einer größeren oder kleineren Förderleistung aktiv vom Führungsring mitgenommen und geführt. Dies bedeutet, dass die Gleitschuhe nicht nur in Umfangsrichtung, sondern auch in radialer Richtung geführt werden.With preference, the radially inner leg of the sliding shoe abuts the radial inner peripheral surface of the guide ring. As a result, an additional guidance is achieved, so that not only is it ensured that the sliding shoe does not lift off from the inner peripheral surface of the stator, but also that at high speeds, part of the contact pressure of the sliding shoe is absorbed by the guide ring. In addition, this embodiment of the shoe and the guide ring of the shoe in the adjustment of the vane pump in the direction of a larger or smaller capacity actively taken and guided by the guide ring. This means that the sliding blocks are guided not only in the circumferential direction but also in the radial direction.
Eine besonders bevorzugte Ausgestaltung sieht vor, dass die axiale Stirnfläche des radial inneren Schenkels des Gleitschuhs und die axial äußere Stirnfläche des Führungsrings in der gleichen Ebene liegen. Außerdem liegen in Weiterbildung der Erfindung die axial äußere Stirnfläche des Führungsringes und die axialen Stirnflächen der Flügel in der gleichen Ebene. Hierdurch wird die Möglichkeit geschaffen, dass durch eine Planfläche eines Deckels, der an den beiden axialen Stirnflächen des Gleitschuhs und des Führungsrings anliegt, jeder Arbeitsraum auf einfache Weise verschlossen werden kann. Außerdem kann durch eine stirnseitige Bearbeitung des Führungsrings sowie der Gleitschuhe und der stirnseitigen Flächen der Flügel eine fluiddichte Anlage gewährleistet werden.A particularly preferred embodiment provides that the axial end face of the radially inner leg of the sliding block and the axially outer end face of the guide ring lie in the same plane. In addition, in the invention, the axially outer end face of the guide ring and the axial end faces of the wings in the same plane. This creates the possibility that each working space can be closed in a simple manner by a flat surface of a lid which bears against the two axial end faces of the sliding shoe and the guide ring. In addition, a fluid-tight system can be ensured by an end-side machining of the guide ring and the sliding blocks and the frontal surfaces of the wings.
