Abstract

1. A rotary piston machine, in particular a blower, comprising a housing (10) having an inlet opening (11) and an outlet opening (12) for a working medium ; a rotor (14) rotatably arranged inside this housing and comprising a drive shaft (16) rotatably journalled about the axis of rotation (15) on one side of the housing (10) ; a disk (17) secured to this shaft ; a plurality of axles (19) which are carried by this disk by their one ends and which extend substantially through the middle of respective forwarding blades (18) ; a ring-like component (20) which carries the other ends of the axles and is located on the opposite side of the housing (10) ; and a cylindrical guide part (22) which is freely rotatably journalled within the rotor (14), however eccentrically to the drive shaft (16), on an axle (21) secured to the opposite side of the housing (10) and which steers the forwarding blades (18) so that the intermediate chambers (23) located between adjacent forwarding blades (18), the housing (10) and the guide part (22) adopt a largest and a smallest volume once for every complete rotation, characterised in that the ring-like component is constructed in the form of a second disk (20) and in that the two disks (17, 20) extend over the entire range of pivotal movement of the forwarding blades (19).

Description

Die Erfindung betrifft ein Rotationskolbengebläse, bei dem ein sich um eine Drehachse drehendes Bauteil mit mehreren auf Achsen schwenkbar angeordneten Förderschaufeln ausgestattet ist, die durch ein außermittig der Drehachse angeordnetes zylindrisches Führungsteil so gelenkt werden, daß der Zwischenraum zwischen den Schaufelflächen einerseits und dem Gebläsegehäuse andererseits bei jeder vollen Umdrehung ein größt- und ein kleinstmögliches Volumen einnimmt.The invention relates to a rotary piston blower in which a component rotates about an axis of rotation is equipped with several conveying blades pivotably arranged on axes, which are eccentric the axis of rotation arranged cylindrical guide part are steered so that the gap between the blade surfaces on the one hand and the fan housing on the other hand with every full revolution occupies a largest and a smallest possible volume.

Der Zweck solcher Gebläse, die nach der Verdrängungsmethode arbeiten, und deren Betrieb auch bei großer mechanischer Herstellungsgenauigkeit nicht ohne Reibungsverluste möglich ist, liegt darin, Gase, in der Hauptsache Luft gegen Druckhöhen zu fördern, die durch Schleuderkraft-(Radial-) oder Propeller-(Axial-)-Ventilatoren nicht mehr mittels wirtschaftlich anwendbaren Drehzahlen erreichbar sind.The purpose of such blowers, working by the positive displacement method, and their operation also at great mechanical manufacturing accuracy is not possible without friction losses lies in the fact that gases are in the main thing is to convey air against pressure heads caused by centrifugal (radial) or propeller (axial) fans can no longer be achieved by means of economically applicable speeds.

Bei einem Drehkolbengebläse dieser Art nach der FR-PS 9 75 985 werden schwenkbar angeordnete umlaufende Förderschaufeln in einem außerhalb desr zu fördernden Mittels gelegenen Steuergehäuse durch Hebel, die ein außermittig der Drehachse angeordnetes feststehendes zylindrisches Führungsteil abtasten, gesteuert. In a rotary piston blower of this type according to FR-PS 9 75 985 are pivotably arranged rotating conveyor blades in a control housing located outside of the means to be conveyed Levers which scan a fixed cylindrical guide part arranged eccentrically from the axis of rotation, controlled.

Dieses Gebläse weist eine ständige Reibung der umtaufenden Führungshebel am feststehenden Führungsteil auf, außerdem ist von Nachteil, daß die umlaufenden Förderschaufeln an drei von vier Umfangsseiten gegenüber dem feststehenden Gehäuse möglichst reibungsarm und dicht abschließend zu gestalten sind, dies erfordert einen hohen mechanischen Aufwand.This fan has a constant friction of the revolving guide lever on the fixed guide part on, also has the disadvantage that the rotating conveyor blades on three of four circumferential sides compared to the stationary housing with as little friction as possible and closes tightly are designed, this requires a high mechanical effort.

Der Erfindung liegt die Aufgabe zugrunde, dieThe invention is based on the object

!5 genannten Nachteile des Gebläses nach der FR-PS 9 75 985 zu beseitigen. Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs l: enthaltenen Merkmale gelöst. Von besonderer Bedeutung ist hierbei die Aufgabe des frei drehbaren Führungsteiles, an dem die Schaufeln durch Fliehkraft und Förderdruck dicht anliegen und der dadurch eine mitdrehende Begrenzung der zwischen den Förderschaufeln gebildeten Förderhohlräume darstellt. ! 5 to eliminate the disadvantages of the fan according to FR-PS 9 75 985. This object is achieved according to the invention by the features contained in the characterizing part of claim 1: solved. from Of particular importance here is the task of the freely rotatable guide part on which the blades pass Centrifugal force and delivery pressure are tight and thereby a co-rotating limitation of the between represents conveying cavities formed by the conveying blades.

Die Position des Führungsteiles im Gehäuse kann nach Lösen der Achsbefestigung durch Schwenkung des Zapfens verstellt werden, dadurch ist eine geringstmögliche Spaltbreite einstellbar.
Ein Ausführungsbeispiel der Erfindung ist anhand der Zeichnung näher erläutert.The position of the guide part in the housing can be adjusted by swiveling the pin after loosening the axle fastening, which means that the smallest possible gap width can be set.
An embodiment of the invention is explained in more detail with reference to the drawing.

Die Wirkungsweise ist gemäß F i g. 1 und 2 wie folgt: Das käfigartige Bauteil 1 mit den Achsen 4 wird mittels der Welle 6 in Drehung versetzt. : Auf den Achsen 4 sind Förderschaufeln 3 so außerhalb ihres Schwerpunktes gelagert, daß sich infolge Fliehkraftwirkung der gerundete leichtere Teil der Förderschaufeln an das zylindrische Führungsteil 2 anlegt. Das Führungsteil 2 ist auf dem Zapfen 7 frei drehbar gelagert.The mode of operation is according to FIG. 1 and 2 as follows: The cage-like component 1 with the axes 4 is set in rotation by means of the shaft 6. : Conveyor blades 3 are on the axes 4 like this stored outside their center of gravity that the rounded lighter part due to the effect of centrifugal force the conveyor blades to the cylindrical guide part 2 applies. The guide part 2 is free on the pin 7 rotatably mounted.

Die Drehachsen des Bauteiles 1 und des zylindrischen Eührungsteiles 2 sind gegeneinander versetzt, dadurch werden die an dem Führungsteil 2 anliegenden Förderschaufeln bei Umdrehung des käfigartigen Bauteiles 1, 4 so geschwenkt, daß zwischen den Förderschaufeln 3, der Gehäusewand 5 und dem zylindrischen Führungsteil 2 eine Förderung der Luft in Pfeilrichtung stattfindet.The axes of rotation of the component 1 and the cylindrical guide part 2 are offset from one another, thereby the conveyor blades resting on the guide part 2 during rotation of the cage-like Component 1, 4 pivoted so that between the conveyor blades 3, the housing wall 5 and the cylindrical guide part 2 a promotion of the air takes place in the direction of the arrow.

Die Gewichts- und Flächenverteilung der Förderschaufeln 3 in bezug auf die jeweilige Schaufelachse 4 istThe weight and area distribution of the conveyor blades 3 in relation to the respective blade axis 4 is

so dabei so angeordnet, daß die Förderschaufeln 3 infolge Fliehkraft nur geringfügig, infolge Gegendruck des Fördermediums jedoch in höherem Maß an das zylindrische Führungsteil 2 angedrückt werden.so arranged so that the conveyor blades 3 due to centrifugal force only slightly, due to the back pressure of the However, the conveying medium is pressed against the cylindrical guide part 2 to a greater extent.
