Description
Die Erfindung betrifft eine Verdrängerpumpe mit einem Flügel zum gegenseitigen Trennen der beiden Kammern im Gehäuseraum des Pumpengehäuses, mit den Merkmalen des Oberbegriffs von Anspruch 1.The The invention relates to a positive displacement pump with a wing for mutual separation of the two chambers in the housing space the pump housing, with the features of the preamble of claim 1.

Die der Erfindung zugrunde liegende Aufgabe besteht nun darin, eine Verdrängerpumpe anzugeben, bei der die Flügelteile gegen an den Flügelspitzen angreifende Kräfte besser abgestützt sind.The The object underlying the invention is now a displacement specify at which the wing parts against at the wing tips attacking forces better supported are.
Diese Aufgabe wird erfindungsgemäß durch eine Verdrängerpumpe gelöst, die die Merkmale des Anspruches 1 aufweist.These The object is achieved by a displacement solved, having the features of claim 1.
Bei der erfindungsgemäßen Verdrängerpumpe liegen die beiden Flügelteilstücke an ihren einander zugekehrten Seitenflächen aneinander an und werden dadurch gegen Verkippen gesichert. Eine Führung der beiden Flügelteilstücke wird dadurch geschaffen, dass die beiden einander zugekehrten Seitenflächen Nuten und Federn aufweisen, die in Längsrichtung des Flügels sich erstrecken, d.h. die orthogonal zur Antriebswelle verlaufen. Die beiden Flügelteilstücke können also lediglich in Längsrichtung aneinander gleiten und werden über die Nuten und Federn daran gehindert, in Richtung der Antriebswelle sich zu verlagern.at the positive displacement pump according to the invention are the two wing sections at their facing each other side surfaces against each other and are thereby secured against tilting. A guided tour of the two wing sections is created by the fact that the two mutually facing side surfaces grooves and having springs in the longitudinal direction of the grand piano extend, i. which are orthogonal to the drive shaft. The two wing sections can so only in the longitudinal direction slide over each other and become over the grooves and springs prevented in the direction of the drive shaft to relocate.
Bei Ausführungsformen ist vorgesehen, dass die Flügelteilstücke symmetrisch ausgebildet sind, ein Flachprofil aufweisen und/oder dass die Flügelteilstücke identisch sind. Diese Ausgestalltungen haben den wesentlichen Vorteil, dass die Flügelteilstücke relativ einfach und somit preiswert herstellbar sind und dass, insbesondere durch die identische Ausgestaltung der Flügelteilstücke, die Lagerhaltung vereinfacht wird.at embodiments it is envisaged that the wing sections symmetrical are formed, have a flat profile and / or that the wing sections identical are. These constructions have the significant advantage that the wing sections relative simple and therefore inexpensive to produce and that, in particular simplified by the identical design of the wing sections, storage becomes.
Eine optimale Führung der Flügelteilstücke auch bei sehr großen Längenänderungen des Flügels wird dadurch erreicht, dass sich die Nuten und Federn über 50% bis 98%, insbesondere 75% bis 95% der Länge des Flügels erstrecken. Hierdurch wird optimal ein Verkanten der Flügelteilstücke verhindert und die Flügelteilstücke stützen sich an Druckpunkten im Rotor ab, die weit voneinander entfernt sind.A optimal leadership the wing sections as well at very large changes in length of the grand piano is achieved by the grooves and feathers exceeding 50% to 98%, in particular 75% to 95% of the length of the wing. This will optimally prevents tilting of the wing sections and the wing sections are supported at pressure points in the rotor, which are far from each other.
Eine weitere Abstützung der Flügelteilstücke sowohl in Richtung der Höhe des Flügels, der Länge des Flügels und der Dicke des Flügels wird dadurch erzielt, dass der Flügel in seiner Höhe, in seiner Länge und/oder in seiner Dicke teilweise abgesetzt ist. Jedes Flügelteilstück weist zumindest abschnittsweise die komplette Höhe, Länge und/oder Dicke des Flügels auf.A further support the wing sections both in the direction of the height of the grand piano, the length of the wing and the thickness of the wing is achieved by the fact that the wing in its height, in its Length and / or Partially discontinued in thickness. Each wing section has at least in sections, the complete height, length and / or thickness of the wing.
Die Nuten und Federn sind so ausgebildet, dass sie eine Labyrinthdichtung bilden. Dabei ist der Freiraum zwischen den Nuten und Federn so bemessen, dass Temperaturschwankungen des Flügels nicht zu einem Klemmen bzw. zum Verlust der Führung führen.The Grooves and springs are designed to provide a labyrinth seal form. The free space between the grooves and springs is like this measured that temperature fluctuations of the wing did not cause a jamming or loss of leadership to lead.
Bei einem besonders bevorzugten Ausführungsbeispiel weisen die Nuten eine Tiefe auf, die 20% bis 50%, insbesondere 25% bis 33%, der Dicke des Flügels entspricht. Bei einer Nuttiefe von 25% der Dicke des Flügels wird der Vorteil erzielt, dass der gesamte Flügel im Wesentlichen gleiche Wanddicken aufweist, sodass bei spritzgegossenen Flügeln keine Hohlräume vorgesehen werden müssen, sodass die Stabilität des Flügels nicht beeinträchtigt wird.at a particularly preferred embodiment the grooves have a depth of 20% to 50%, especially 25% to 33%, the thickness of the wing equivalent. At a groove depth of 25% of the thickness of the wing becomes the advantage is achieved that the entire wing is substantially the same Has wall thicknesses, so that injection-molded wings no cavities must be provided so the stability of the grand piano is not affected.
Ein bevorzugtes Ausführungsbeispiel sieht vor, dass die Flügelteilstücke gleichmäßige Wandstärken aufweisen. Dadurch wird die Möglichkeit geschaffen, das die Flügelteilstücke problemlos im Spritzgießverfahren hergestellt werden können. Im Druckgussverfahren hergestellte Flügelteilstücke sind ebenfalls denkbar.One preferred embodiment provides that the wing sections have uniform wall thicknesses. This will be the possibility created that the wing sections easily in injection molding can be produced. Die castings made by die casting are also conceivable.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung ein besonders bevorzugtes Ausführungsbeispiel im Einzelnen beschrieben ist. Dabei können die in der Zeichnung dargestellten sowie in der Beschreibung und in den Ansprüchen erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein.Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawing, a particularly preferred embodiment is described in detail. It can the features shown in the drawing and in the description and in the claims mentioned in each case be essential to the invention individually or in any combination.
