Abstract
Description
Die vorliegende Erfindung betrifft eine Verdrängermaschine für kompressible Medien gemäss Oberbegriff des Anspruches 1.The The present invention relates to a positive displacement machine for compressible media according to the preamble of Claim 1.
Verdrängermaschinen
dieser Art sind beispielsweise aus der
Während des Betriebs einer solchen Verdrängermaschine werden in der Verdränger- oder Förderkammer zwischen dem spiralförmig ausgebildeten Verdrängerkörper und den beiden Umfangswänden mehrere, etwa sichelförmige Arbeitsräume eingeschlossen, die sich vom Einlass durch die Förderkammer hindurch zum Auslass hin bewegen, wobei ihr Volumen ständig verringert und der Druck des Arbeitsmittels dementsprechend erhöht wird. Ein nach diesem Prinzip arbeitender Verdichter zeichnet sich durch eine pulsationsarme Förderung des gasförmigen Arbeitsmittels, z. B. Luft, aus und könnte daher mit Vorteil unter anderem für Aufladezwecke bei Brennkraftmaschinen herangezogen werden.While the operation of such a displacement machine are in the displacement or delivery chamber between the spiral-shaped displacer and the two peripheral walls of several, approximately sickle-shaped Workspaces enclosed by the inlet through move the delivery chamber through to the outlet, wherein their volume constantly decreases and the pressure of the working fluid is increased accordingly. A working according to this principle Compressor is characterized by a pulsation-poor promotion the gaseous working fluid, z. As air, and could therefore with advantage inter alia for Aufladen purposes in internal combustion engines be used.
Um zu verhindern, dass sich die Antriebswelle im Betrieb durchbiegt, insbesondere bei hohen Drehzahlen, sind bei den vorstehend erwähnten bekannten Verdrängermaschinen die Gegengewichte sehr nahe an der Exzenterscheibe angeordnet. Die Lager für die Antriebswelle sind möglichst nahe an die Gegengewichte heran gerückt, was ebenfalls zur Verringerung bzw. Vermeidung einer Durchbiegung der Antriebswelle beiträgt. Dabei darf aber der Abstand zwischen demjenigen Lager, das bezüglich der Exzenterscheibe auf der Seite der Antriebsscheibe liegt, und dieser Antriebsscheibe nicht zu gross werden, da sonst die Gefahr einer Durchbiegung der Antriebswelle im Betrieb besteht.Around to prevent the drive shaft from bending during operation, especially at high speeds, are in the aforementioned known displacement machines the counterweights very close arranged on the eccentric disc. The bearings for the drive shaft are as close as possible to the counterweights, which also helps to reduce or avoid deflection of the Drive shaft contributes. However, the distance between that bearing, with respect to the eccentric on the side of the drive pulley is located, and this drive pulley not too big, otherwise the risk of bending the Drive shaft is in operation.
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Verdrängermaschine der eingangs genannten Art zu schaffen, bei der das ausserhalb des Gehäuses liegende Antriebsorgan auch verhältnismässig weit vom Gehäuse angeordnet werden kann, ohne dass sich die Antriebswelle im Betrieb zu stark durchbiegt, auch bei hohen Drehzahlen nicht.Of the The present invention is based on the object, a displacement machine of the type mentioned above, in which the outside of the Housing lying drive member also relatively can be placed far from the case without getting the drive shaft deflects too much during operation, even at high speeds No speeds.
Diese Aufgabe wird erfindungsgemäss mit einer Verdrängermaschine mit den Merkmalen des Anspruches 1 gelöst.These Task is according to the invention with a positive displacement machine solved with the features of claim 1.
Die Abstützung der Antriebswelle an ihrem aus dem Gehäuse herausragenden, antriebsseitigen Ende mittels eines weiteren Lagers ermöglicht es, den Abstand zwischen dem Antriebsorgan und demjenigen Lager im Innern des Gehäuses, das bezüglich der Exzenterscheibe auf der Seite des Antriebsorgans liegt, freier zu wählen.The Supporting the drive shaft at its out of the housing outstanding, drive-side end by means of another camp allows the distance between the actuator and the one inside the case, which is relative to the eccentric disc on the side of the drive member is more free to choose.
Bevorzugte Weiterausgestaltungen der erfindungsgemässen Verdrängermaschine bilden Gegenstand der abhängigen Ansprüche.preferred Further refinements of the displacement machine according to the invention form the subject of the dependent claims.
Eine besondere Ausführungsform einer erfindungsgemässen Verdrängermaschine ist im Anspruch 13 definiert.A particular embodiment of an inventive Displacement machine is defined in claim 13.
Im Folgenden werden anhand der Zeichnungen Ausführungsbeispiele des Erfindungsgegenstandes näher erläutert. Es zeigt rein schematisch:in the Below, embodiments will be described with reference to the drawings of the subject invention explained in more detail. It shows purely schematically:
