Description
Die Erfindung betrifft eine Einflügelvakuumpumpe mit einem topfförmigen Gehäuse, einem exzentrisch im Gehäuse drehbar gelagerten, teilweise aus Sintermetall bestehenden Rotor; einem im Rotor orthogonal zur Drehachse verschieblich gelagerten Flügel, und einem die vom Flügel getrennten Arbeitsräume verschließenden Gehäusedeckel.The The invention relates to a single-wing vacuum pump with a cup-shaped Casing, one eccentric in the housing rotatably mounted, partially made of sintered metal rotor; a rotatably mounted in the rotor orthogonal to the axis of rotation wings, and one from the wing separate workrooms occlusive Cover.
Vakuumpumpen
sind z.B. aus folgenden Dokumenten bekannt:
Der Erfindung liegt daher die Aufgabe zu Grunde, eine Vakuumpumpe, insbesondere eine Einflügelvakuumpumpe bereit zu stellen, die einfacher herstellbar ist.Of the The invention is therefore based on the object, a vacuum pump, in particular a single-wing vacuum pump ready to provide, which is easier to produce.
Diese Aufgabe wird erfindungsgemäß mit einer Einflügelvakuumpumpe gelöst, die die Merkmale des Anspruchs 1 aufweist.These Task is according to the invention with a A single-blade solved, having the features of claim 1.
Da nur Abschnitte des Rotors aus einem Metall gefertigt sind, welches ein geringeres Gewicht aufweist, wird das Gesamtgewicht des Rotors reduziert und das Massenträgheitsmoment verringert. Hierdurch wird erreicht, dass die Leistungsaufnahme der Vakuumpumpe geringer ist als bei herkömmlichen Aggregaten. Insbesondere werden die Teile des Rotors, die große Momente übertragen müssen, nach wie vor aus Metall gefertigt, wohingegen die Abschnitte des Rotors aus einem anderen Werkstoff bestehen können, die weniger stark beansprucht werden.There only portions of the rotor are made of a metal, which has a lower weight, the total weight of the rotor reduced and the moment of inertia reduced. This ensures that the power consumption of Vacuum pump is lower than in conventional units. Especially The parts of the rotor, which have to transmit large moments, are still made of metal whereas the sections of the rotor are made of a different one Material can exist, which are less stressed.
Erfindungsgemäß weist der Rotor einen Rotorgehäuseträger (Rotorachse) und ein auf die Rotorachse aufgesetztes Rotorgehäuse auf. Die Rotorachse besitzt die Aufgabe, das zum Antrieb der Pumpe erforderliche Drehmoment einzubringen und den Rotor mit Flügel in Drehung zu versetzen. Das Rotorgehäuse besitzt die Aufgabe, den Flügel aufzunehmen und zu führen. Außerdem weist die Rotorachse zur Aufnahme des Rotorgehäuses wenigstens zwei parallel zur Drehachse abragende Dorne auf. Demgegenüber besitzt das Rotorgehäuse zwei auf die Dorne aufsteckbare Hülsen. Die Form der Dorne und der Hülsen ist vorteilhaft so gewählt, dass nicht nur das Rotorgehäuse sicher von der Rotorachse gehalten wird, sondern dass auch die den Flügel haltende Führungskräfte über die Hülsen von den Dornen abgestützt werden. Die Herstellung eines derartigen Rotors ist wesentlich einfacher.According to the invention the rotor has a rotor housing carrier (rotor axis) and a rotor housing mounted on the rotor housing. The rotor axis has the task, the torque required to drive the pump bring in and put the rotor with wings in rotation. The rotor housing owns the task, the wing to take up and lead. Furthermore has the rotor axis for receiving the rotor housing at least two parallel on the axis of rotation protruding spines. In contrast, the rotor housing has two the spikes attachable sleeves. The shape of the spines and pods is advantageously chosen that not only the rotor housing safely held by the rotor axis, but that the Holding wings Executives over the sleeves supported by the thorns become. The production of such a rotor is much easier.
Da die Antriebskräfte und die beim Beschleunigen und Verzögern einwirkenden Momente hauptsächlich von der Rotorachse abgestützt werden müssen, besteht diese aus Sintermetall. Bei der Führung des Flügels spielen derartige Kräfte und Momente eine untergeordnete Rolle, wobei Abdichtungsprobleme in den Vordergrund rücken. Daher besteht das Rotorgehäuse erfindungsgemäß aus Kunststoff. Kunststoffe besitzen, insbesondere dann, wenn sie mit einem Metall gepaart sind, hier mit einem aus Metall bestehenden Flügel, hervorragende tribologische Eigenschaften, wodurch Reibungskräfte auf ein Minimum reduziert werden, was auch einer übermäßigen Erwärmung entgegen wirkt.There the driving forces and the moments acting on acceleration and deceleration mainly of supported the rotor axis Need to become, this consists of sintered metal. Play in the lead of the wing such forces and moments a minor role, with sealing problems Move to the front. Therefore, there is the rotor housing according to the invention made of plastic. plastics especially when paired with a metal, here with a metal wing, excellent tribological properties, causing friction be reduced to a minimum, which also prevents excessive heating acts.
Eventuell kann das Rotorgehäuse noch die Aufgabe besitzen, die Beiden Arbeitsräume gegeneinander abzudichten, indem das Rotorgehäuse die Innenumfangswand berührt. Besteht das Pumpengehäuse aus Metall und das Rotorgehäuse aus Kunststoff, dann werden die Reibungskräfte verringert und eine gute Abdichtung erzielt.Perhaps can the rotor housing still have the task to seal the two work spaces against each other, by the rotor housing the inner peripheral wall touches. Is the pump housing made of metal and the rotor housing made of plastic, then the frictional forces are reduced and a good one Sealing achieved.
Bevorzugte Ausführungsbeispiele sehen für das Rotorgehäuse folgende Kunststoffe vor: Polyetheretherketon (PEEK), Polyethersulfid (PES), syndiotaktisches Polystyrol (SPS) oder ein Polyphenylensulfid (PPS)Diese Kunststoffe sind äußerst abriebfest und beständig gegen Schmiermittel.preferred embodiments see for that rotor housing following plastics: polyetheretherketone (PEEK), polyethersulfide (PES), syndiotactic polystyrene (SPS) or a polyphenylene sulfide (PPS) These plastics are extremely abrasion resistant and resistant against lubricant.
Eine einfache Montage des Rotors wird dadurch erzielt, dass das Rotorgehäuse auf die Rotorachse, insbesondere axial aufgesteckt ist. Steckverbindungen sind leicht und insbesondere ohne Werkzeug herstellbar. Außerdem wirken beim Betrieb der Vakuumpumpe keine Kräfte in oder entgegen der Steckrichtung, sodass ein Lösen der Steckverbindung nicht zu befürchten ist.A easy mounting of the rotor is achieved by the rotor housing on the rotor axis, in particular axially attached. connectors are easy and especially without tools produced. In addition, act during operation of the vacuum pump no forces in or against the plug-in direction, so a release the plug connection is not to be feared is.
Hierfür erstrecken sich die Dorne zumindest über einen Teil der Höhe der Flügel. Um den Flügel auch bei relativ kurzen Dornen, die sich z.B. über eine Höhe von 10%–20% des Flügels erstrecken, sicher halten und führen zu können, ist der andere, von den Dornen nicht durchgriffene Teil der Hülsen mittels Verstrebungen ausgesteift. Hierdurch wird außerdem Material und dadurch Gewicht eingespart.For this purpose, the spines extend at least over part of the height of the wings. In order to safely hold and guide the wing even with relatively short spines, which extend over a height of 10% -20% of the wing, for example, the other, not penetrated by the spines part of the sleeves with stiffened braces. This also saves material and thus weight.
