Abstract
Die Erfindung betrifft eine Vakuumpumpe mit einem Flügel, einem Pumpengehäuse und einem darin drehbar gelagerten Rotor, wobei der Flügel eine konstante Länge aufweist und verschieblich im Rotor gelagert ist und die Flügelspitzen beidseitig aus dem Rotor radial herausragen und an der Innenumfangsfläche des Pumpengehäuses anliegen, wodurch der Flügel einen Saugraum und einen Druckraum definiert, wobei der Flügel einteilig ausgebildet ist und aus Metall besteht.The invention relates to a vacuum pump with a wing, a pump housing and a rotor rotatably mounted therein, wherein the wing has a constant length and is slidably mounted in the rotor and the wing tips on both sides protrude radially from the rotor and abut the inner peripheral surface of the pump housing, whereby the Wing defines a suction chamber and a pressure chamber, wherein the wing is integrally formed and made of metal.
Description
Die Erfindung betrifft eine Vakuumpumpe mit einem Flügel, einem Pumpengehäuse und einem darin drehbar gelagerten Rotor, wobei der Flügel eine konstante Länge aufweist und verschieblich im Rotor gelagert ist und die Flügelspitzen beidseitig aus dem Rotor radial herausragen und an der Innenumfangsfläche des Pumpengehäuses anliegen, wodurch der Flügel einen Saugraum und einen Druckraum definiert, wobei der Flügel einteilig ausgebildet ist und aus Metall besteht.The The invention relates to a vacuum pump with a wing, a pump housing and a rotatably mounted therein rotor, wherein the wing is a constant Length and slidably mounted in the rotor and the wing tips protrude radially from both sides of the rotor and on the inner peripheral surface of pump housing abut, causing the wing defines a suction chamber and a pressure chamber, wherein the wing in one piece is formed and made of metal.

Der Erfindung liegt die Aufgabe zugrunde, eine Vakuumpumpe bereitzustellen, bei welcher der Verschleiß minimal ist, der Flügel aber einfach und preiswert hergestellt werden kann.Of the Invention has for its object to provide a vacuum pump, at which the wear is minimal is, the wing but can be easily and inexpensively manufactured.
Diese Aufgabe wird mit einer Pumpe der eingangs genannten Art dadurch gelöst, dass der Flügel im Bereich seiner Flügelspitze auf der Druckseite abgeflacht ist, wobei die Abflachung unter einem Winkel zur Längsachse des Flügels steht, und der Flügel auf der Saugseite von seiner Flügelspitze in einer stetigen Krümmung in seine Seitenfläche übergeht.These Task is characterized by a pump of the type mentioned by solved, that the wing is in Area of his wing tip flattened on the pressure side, the flattening under a Angle to the longitudinal axis of the grand piano stands, and the wing on the suction side of his wing tip in a constant curvature merges into its side surface.
Bei einem bevorzugten Ausführungsbeispiel der Erfindung wird das Gehäuse der Vakuumpumpe aus Stahl hergestellt, was den Vorteil hat, dass das Gehäuse hohe Kräfte aufnehmen kann und dennoch einfach bearbeitbar ist. Der Flügel besteht aus einem Metall, welches härter ist, als das Gehäuse der Vakuumpumpe, insbesondere härter als die Innenumfangsfläche des Pumpengehäuses. Dabei besteht der Flügel zum Beispiel Titan oder einer Titanlegierung, Stahl, Edelstahl, Aluminium oder Messing.at a preferred embodiment of Invention is the housing The vacuum pump made of steel, which has the advantage that the housing high forces can be recorded and yet easy to edit. The wing exists made of a metal, which is harder is, than the case the vacuum pump, in particular harder as the inner circumferential surface of the pump housing. There is the wing for example titanium or a titanium alloy, steel, stainless steel, Aluminum or brass.
Optimale Andruckkräfte des Flügels an die Innenumfangswand werden dadurch erzielt, dass der Flügel im Bereich seiner Flügelspitze auf der Druckseite abgeflacht ist, wobei die Abflachung unter einem Winkel zur Längsachse des Flügels steht. Dieser Flügel kann zudem preiswert hergestellt werden, da die der abgeflachten Seite gegenüber liegende Seite lediglich eine stetige Krümmung aufweist.optimal pressure forces of the grand piano to the inner peripheral wall are achieved by the fact that the wing in the area his wingtip flattened on the pressure side, the flattening under a Angle to the longitudinal axis of the grand piano stands. This wing can also be produced inexpensively, as the flattened Side opposite lying side only has a continuous curvature.
Mit Vorzug ist die Innenumfangsfläche des Pumpenraums eine Kreiszylinderfläche. Der Flügel vollzieht dann innerhalb des Schlitzes des Rotors eine sinusförmige Hin- und Herbewegung. Die Kräfteverteilung bzw. die Lastwechsel an der Spitze des Flügels sind dann kontinuierlich und nicht abrupt.With Preference is the inner peripheral surface the pump chamber, a circular cylindrical surface. The wing then completes within of the slot of the rotor a sinusoidal float. The distribution of forces or the load changes at the top of the wing are then continuous and not abruptly.
Bei einer Weiterbildung ist vorgesehen, dass parallel zur Flügelspitze Ausnehmungen oder Durchbrüche vorgesehen sind und der Flügel aufgrund der Ausnehmungen oder der Durchbrüche in dessen Längsrichtung geringfügig elastischer ist. Hierdurch kann der Flügel einem sich wärmebedingt dehnenden Druckraum anpassen, sodass die Dichtigkeit sowohl bei kalten als auch bei warmen Vakuumpumpen nach wie vor gewährleistet ist.at a development is provided that parallel to the wing tip Recesses or breakthroughs are provided and the wing due to the recesses or the openings in the longitudinal direction slight is more elastic. This allows the wing a heat-related adjust the expanding pressure chamber, so that the tightness in both cold as well as with warm vacuum pumps are still guaranteed is.
