Abstract
Description
Die Erfindung betrifft eine Flügelzellenpumpe mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a vane pump with the features of the preamble of
Sie geht von der deutschen Offenlegungsschrift
Nachteilig bei diesem bekannten Stand der Technik ist, dass das in die Pumpenkammern ein- und ausströmende Schmiermittel durch die Stützstege behindert wird, was Strömungsverluste zur Folge hat. Desweiteren verursacht das Vorbeistreichen der Flügelkanten an den Stützstegkanten ein Geräusch. Jedes Vorbeistreichen der Flügelkanten an den Stützstegkanten führt darüber hinaus zu einem Abscheren der Schmiermittelsäule. Dadurch werden die langen Molekülketten des Schmiermittels zerstört und die Viskosität des Schmiermittels in nachteiliger Weise verändert.A disadvantage of this known prior art is that the incoming and outgoing lubricant in the pump chambers is hindered by the support webs, resulting in flow losses. Furthermore, the passing of the wing edges at the support web edges causes a noise. Each passing of the wing edges on the support web edges also leads to a shearing of the lubricant column. This destroys the long molecular chains of the lubricant and adversely affects the viscosity of the lubricant.
Aufgabe der vorliegenden Erfindung ist es, eine Maßnahme aufzuzeigen, um die oben genannten Nachteile zu vermeiden.Object of the present invention is to show a measure to avoid the above-mentioned disadvantages.
Diese Aufgabe wird durch das Merkmal im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is achieved by the feature in the characterizing part of
Erfindungsgemäß werden die Stützstege bei gleichzeitiger Minimierung der Anzahl der Kanten entfernt. In vorteilhafter Weise wird die axiale Führung der Flügel im Bereich des Fluidzuflusses und des Fluidabflusses ohne gehäuseseitige Stützstege gewährleistet. Vorzugsweise wird in eine, im Außenrotor stirnseitig umlaufende Nut der ringförmige Axialanschlag eingelegt. Alternativ kann der ringförmige Axialanschlag auch in eine stirnseitig umlaufende Nut im Bereich des Innenrotors eingelegt werden. Der ringförmige Axialanschlag ist somit in den Rotor eingelegt, in dem auch die Flügel schwenkbar gelagert sind. Der Axialanschlag überdeckt die Flügel vorzugsweise nur im Bereich der schwenkbaren Lagerung.According to the invention, the support webs are removed while minimizing the number of edges. Advantageously, the axial guidance of the wings is ensured in the region of the fluid inlet and the fluid outlet without housing-side support webs. Preferably, in a, in the outer rotor frontally circumferential groove of the annular axial stop is inserted. Alternatively, the annular axial stop can also be inserted into a frontally circumferential groove in the region of the inner rotor. The annular axial stop is thus inserted into the rotor, in which the wings are pivotally mounted. The axial stop preferably covers the wings only in the area of the pivotable mounting.
Alternativ haben die Flügel in dem vom Axialanschlag überdeckten Bereich eine Ausklinkung, in die der Axialanschlag einlegbar ist. Die Geometrie der Ausklinkung ist so ausgeführt, dass der radiale Spalt zwischen dem schwenkbeweglichen Flügel und dem Axialanschlag bei jeder Flügelstellung minimal ist, um die einzelnen Pumpenkammern gegeneinander abzudichten. Da der Axialanschlag im Gehäuse zwischen der Saug- und Druckkammer axial anliegt, ist durch die Überdeckung des Flügels mit dem Axialanschlag, der Flügel auch im Bereich des Fluidzuflusses und des Fluidabflusses axial geführt. Dadurch können erfindungsgemäß die störenden Stützstege entfallen.Alternatively, the wings in the area covered by the axial stop a notch, in which the axial stop can be inserted. The geometry of the notch is designed so that the radial gap between the pivoting blade and the axial stop at each blade position is minimal in order to seal the individual pump chambers against each other. Since the axial stop in the housing between the suction and pressure chamber abuts axially, the wing is axially guided by the overlap of the wing with the axial stop, in the area of the fluid inlet and the fluid drain. As a result, according to the invention, the disturbing support webs can be omitted.
