Description
Drehkolbenverdichter mit zwischen feststehendem Gehäusemantel und umlaufender Kolbentrommel angeordnetem, sichelförmigem Arbeitsraum und mit axial verschiebbaren Seitenwänden Die Erfindung betrifft einen Drehkolbenverdichter mit zwischen feststehendem Gehäusemantel und umlaufender Kolbentrommel angeordnetem, sichelförmigem Arbeitsraum und axial verschiebbaren Seitenwänden. Sie besteht darin, daß die Seitenwände des Arbeitsraumes zusammen mit der Kolbentrommel auf der Antriebswelle axial verschiebbar angeordnet sind, damit sie sich in ihrer axialen Lage unabhängig von den auf die Welle wirkenden Kräften nach dem Zylindermantel einstellen können. Die Seitenwände sind von einem unter Förderdruck stehenden Schmierflüssigkeitsraum umschlossen und werden von der mit dem Druckraum des Verdichters in Verbindung stehenden Schmierflüssigkeit nachgiebig an den Mantel gedrückt.Rotary piston compressor with between the fixed housing shell and rotating piston drum arranged, sickle-shaped working space and with axially displaceable side walls The invention relates to a rotary piston compressor with arranged between the fixed housing shell and the rotating piston drum, sickle-shaped work space and axially movable side walls. It consists in that the side walls of the working space together with the piston drum on the drive shaft are arranged axially displaceable so that they are independent in their axial position of the forces acting on the shaft according to the cylinder jacket. The side walls are made up of a lubricating fluid space that is under delivery pressure are enclosed and are connected to the pressure chamber of the compressor Lubricant pressed resiliently against the jacket.
Ein Ausführungsbeispiel eines Drelikolbenverdichters nach der Erfindung ist auf der Zeichnung dargestellt.An embodiment of a three-piston compressor according to the invention is shown on the drawing.
Abb. i ist ein Schnitt nach der Linie I-1 der Abb. z und Abb.2 ein Schnitt nach der Linie II-II der Abb. i.Fig. I is a section along the line I-1 of Fig. Z and Fig.2 a Section along the line II-II in Fig. I.
Das Gehäuse a enthält den Saugraum b. den sichelförmigen Arbeitsraum c und dell Druckraum d. Die Antriebswelle e ruht in den Lagern f des Verdichters. Der Arbeitsraum c ist innen von der in der Pfeilrichtung umlaufenden, mit dem Kolben g verseltenen Kolbentrommel h, außen von dem die Einlaßöffnungen i und die Auslaßöffnungen k enthaltenden Zvlindermantel l und seitlich von den Wänden in begrenzt. Das Gehäuse a wird auf der einen Seite von dem das Glasfenster fa aufweisenden Deckel o, auf der anderen Seite von dem die Stopfbüchse p aufnehmenden Deckel q gasdicht nach außen abgeschlossen.The housing a contains the suction chamber b. the sickle-shaped work space c and dell pressure space d. The drive shaft e rests in the bearings f of the compressor. The working space c is bounded on the inside by the piston drum h rotating in the direction of the arrow with the piston g, on the outside by the cylinder jacket l containing the inlet openings i and the outlet openings k and laterally by the walls in. The housing a is closed on one side by the cover o, which has the glass window fa, and on the other side by the cover q, which holds the stuffing box p, in a gas-tight manner to the outside.
Die Seitenwände in des Arbeitsraumes sind in bekannter Weise als umlaufende Scheiben ausgebildet, die wie die Kolbentrommel la durch den Keil r auf der Antriebswelle e befestigt sind und mit ihren Außenrändern dichtend auf dem Zvlindermantell gleiten. Auf diese Weise wird ein verlustbringendes Rückströmen des Fördermittels aus dem Druckraum d in den Saugraum b vermieden. Die Schmierung und Abdichtung der Gleitflächen am Rand der Scheiben yra wird durch unter Förderdruck stehende Schmierflüssigkeit erzielt, die aus dem als Schmiermittelsammler ausgebildeten Druckraum cl durch die Röhre s in solcher Menge in die beidseitig der Scheiben in, angeordneten Hohlräume x gedrückt wird, daß es diese ganz ausfüllt. Damit wird außer einer einwandfreien Schmierung und Abdichtung der genannten Gleitflächen zugleich auch eine gute Schmierung der Lagerfund der Stopfbüchse p sowie eine Verbesserung der Abdichtung des Gehäuses nach außen erzielt, weil das -gasförmige Arbeitsmittel weder nach der Stopfbüchse p noch nach den übrigen Dichtungsstellen gelangen kann. Ein Teil des in den linken Hohlraum x geförderten Schmiermittels strömt durch die in der Welle e und in der Kolbentrommel h vorgesehenen Kanäle t zu den Kolben g, um dort ebenfalls sowohl als Schmier- als auch als Abdichtungsmittel zu wirken. Das Schmiermittel, «-elches hierbei in den Arbeitsraum überströmt, wird von der Kolbentrommel h zusammen mit dem Arbeitsmittel wieder in den Druckraum d zurückgefördert. Der auf die unausgeglichene Stirnfläche der Welle e wirkende Schmiermitteldruck wird von dem auch als Axiallager ausgebildeten linken Kugellager f aufgenommen. Die Scheiben m sind mitsamt der Kolbentrommel axial beweglich auf der Welle e aufgekeilt, damit sie sich in ihrer axialen Lage unabhängig von der mit dem veränderlichen Schmiermitteldruck sich ändernden axialen Einstellung der Welle nach dem zwischen den Abstandsstücken u, v und w eingeklemmten Zylindermantel richten können.The side walls in the working space are designed in a known manner as circumferential disks which, like the piston drum la are fastened by the wedge r on the drive shaft e and slide with their outer edges sealingly on the cylinder jacket. In this way, a loss-making backflow of the conveying medium from the pressure chamber d into the suction chamber b is avoided. The lubrication and sealing of the sliding surfaces on the edge of the disks yra is achieved by lubricating fluid under feed pressure, which is pressed from the pressure chamber cl designed as a lubricant collector through the tube s into the cavities x arranged on both sides of the disks in such an amount that it is these completely fills out. In addition to proper lubrication and sealing of the mentioned sliding surfaces, this also ensures good lubrication of the bearing found of the stuffing box p and an improvement in the sealing of the housing to the outside, because the gaseous working medium can neither reach the stuffing box p nor the other sealing points. Part of the lubricant conveyed into the left cavity x flows through the channels t provided in the shaft e and in the piston drum h to the pistons g in order to act there as both a lubricant and a sealing agent. The lubricant, which flows over into the working space, is conveyed back into the pressure space d by the piston drum h together with the working medium. The lubricant pressure acting on the unbalanced end face of the shaft e is absorbed by the left ball bearing f, which is also designed as a thrust bearing. The disks m, together with the piston drum, are wedged axially movably on the shaft e so that their axial position can be aligned with the cylinder jacket clamped between the spacers u, v and w regardless of the axial setting of the shaft that changes with the changing lubricant pressure.
