Description

Die Erfindung betrifft eine Zweischeiben-Rotationskolben maschine mit Hubeingriff zwischen exzentrisch in einem stationären Gehäuse drehbar gelagerten Rotoren und je einem einen jeden Rotor radial durchsetzenden Leistungeteil sowie mit Schlupfeingriff zwischen dem Gehäusemantel und den Leistungsteilen, die innerhalb des Rotors radial zum Gehäusemantel geführt sind, derart, daß sie mit ihren Enden an zwei diametral gegenüberliegenden Stellen mit dem Gehäusemantel je zwei Arbeitskammern bildend in dichtender Gleitanlage gehalten sind.The invention relates to a two-disc rotary piston machine with stroke engagement between rotors eccentrically rotatably mounted in a stationary housing and a power part penetrating each rotor radially as well as with slip engagement between the housing shell and the power parts, which are guided radially to the housing shell within the rotor, such that that their ends are held at two diametrically opposite points with the housing jacket forming two working chambers in a sealing slide system.

Eine Zweischeiben-Rotationskolbenmaschine der vorstehend genannten Gattung ist bereits aus der DD-PS 46 761 bekannt. Bei dieser bekannten Rotationskolbenmaschine ist im Inneren eines jeden Rotors eine Ausnehmung vorgesehen, in welcher eine geschlossene Öse untergebracht ist, von welcher an einander gegenüberliegenden Seiten sich je ein Arm des Leistungsteils erstreckt. Die in jedem Rotorinnenraum aufgenommene Öse umgibt einen in einem Seitenteil angeordneten, feststehenden Führungszapfen, so daß die als Führungsbahn dienende Innenoberfläche der Öse sich gleitend um den Führungszapfen zu drehen vermag. Zwischen den beiden Rotoren ist ein Ausgleichsgewicht vorgesehen.A two-disc rotary piston machine of the aforementioned type is already from the DD-PS 46 761 known. In this known rotary piston machine, a recess is provided in the interior of each rotor, in which a closed eyelet is accommodated, from each of which an arm of the power section extends on opposite sides. The eyelet received in each rotor interior surrounds a fixed guide pin arranged in a side part, so that the inner surface of the eyelet, which serves as a guideway, can rotate smoothly around the guide pin. A balance weight is provided between the two rotors.

Die bekannte Rotationskolbenmaschine kann nur mit recht großen mechanischen Verlusten betrieben werden, weil die Lagerung der Leistungsteile viele Reibungsflächen aufweist und das Ausgleichsgewicht eine tote Masse darstellt, die leistungsvermindernd in Drehung versetzt werden muß. Ein weiterer Nachteil der bekannten Maschine liegt darin, daß die als geschlossenes Oval ausgebildete Führungsbähn für den Führungszapfen einen geteilten Rotor erfordert, da anderweitig ein Zusammenbau der Teile nicht möglich ist.The known rotary piston machine can only be operated with very large mechanical losses, because the bearing of the power parts has many friction surfaces and the balance weight represents a dead mass that must be set in rotation to reduce performance. A further disadvantage of the known machine is that the guide track designed as a closed oval for the guide pin requires a divided rotor, since otherwise the parts cannot be assembled.

Der Erfindung liegt die Aufgabe zugrunde, eine Rotationskolbenmaschine der vorstehend genannten Gattung so auszubilden, daß bei einfachem Aufbau der Maschine die mechanischen Verluste klein gehalten werden und Gewichte zum Massenausgleich entbehrlich sind.The invention is based on the object of designing a rotary piston machine of the type mentioned above in such a way that the mechanical losses are kept small with a simple construction of the machine and weights for mass balancing are unnecessary.

Diese Aufgabe wird erfindungsgemäß gelöst durch die folgenden Merkmale.

  • a) Jeder Rotor ist mit je einem mit dem Gehäuse drehfest verbundenen Lagerzapfen gelagert,
  • b) die Leistungsteile sind jeweils mit Hilfe eines mit dem Lagerzapfen drehfest verbundenen Führungszapfens, der in eine Führungsnut der Leistungsteile eingreift, geführt, wobei die Führungszapfen um 1800 zueinander versetzt angeordnet sind,
  • c) in den Endbereichen der Leistungsteile sind in an sich bekannter Weise federbeaufschlagte Dichtelemente eingelassen.
This object is achieved according to the invention by the following features.
  • a) Each rotor is supported with a pivot pin connected to the housing in a rotationally fixed manner,
  • b) the power parts are each guided with the aid of a guide pin which is connected in a rotationally fixed manner to the bearing pin and which engages in a guide groove of the power parts, the guide pins being arranged offset from one another by 1800,
  • c) in the end regions of the power parts, spring-loaded sealing elements are embedded in a manner known per se.

Der mit Hilfe der Erfindung erzielbare technische Fortschritt ist in erster Linie darin zu sehen, daß durch die Ausbildung der Leistungsteil-Lagerung und durch die Versetzung der Führungszapfen um 180° relativ zueinander erheblich weniger Leistung als bei der bekannten Vorrichtung in der Maschine verzehrt wird, so daß an der Abtriebswelle eine höhere Leistung abnehmbar ist.The technical progress that can be achieved with the aid of the invention is primarily to be seen in the fact that considerably less power is consumed in the machine than in the known device by the design of the power part mounting and by the offset of the guide pins by 180 ° relative to one another that a higher power is removable on the output shaft.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigt:

  • Fig. 1 einen Längsschnitt durch die Maschine und
  • Fig. 2 einen Querschnitt durch die Maschine.
An embodiment of the invention is shown in the drawing and will be described in more detail below. It shows:
  • Fig. 1 shows a longitudinal section through the machine and
  • Fig. 2 shows a cross section through the machine.

Wie in der Zeichnung dargestellt, besitzt die Maschine zu beiden Seiten der Rotoren 1, 21 Seitengehäuse 5, 25 sowie zwischen den Seitengehäusen angeordnete Gehäusemäntel 3, 23. Die Rotoren 1,21 sind mit einem Abtriebskörper 50 verschraubt und drehen sich um eine gemeinsame Achse. Die Gehäuseteile sind durch Paßstifte zentriert und werden durch Zuganker 18,38, die auf der einen Seite in ein Einlaßgehäuse 49 fest eingeschraubt sind, und an dem Seitengehäuse 5, 25 durch Muttern zusammengehalten. An den den Rotoren gegenüberliegenden Stirnseiten sind Lagerflansche 4, 24 angeschraubt, die durch Lager 6, 26 mit Lagerzapfen 7,27 drehbar verbunden sind.As shown in the drawing, the machine has on both sides of the rotors 1, 21 side housings 5, 25 and housing shells 3, 23 arranged between the side housings. The rotors 1, 21 are screwed to an output body 50 and rotate about a common axis. The housing parts are centered by dowel pins and are by tie rods 18, 38 on one side are screwed tightly into an inlet housing 49, and held together on the side housing 5, 25 by nuts. Bearing flanges 4, 24 are screwed to the end faces opposite the rotors, which are rotatably connected by bearings 6, 26 to journals 7, 27.

Jeder der Rotoren 1, 21 hat quer zu seiner Drehachse eine durchgehende Bohrung, in welcher jeweils ein Leistungsteil 2,22 in Längsrichtung verschieblich aufgenommen ist. Jedes Leistungsteil 2, 22 weist in der Mitte seiner Längsabmessung eine quer zur Leistungsteil-Längsachse verlaufende Führungsnut 31 auf, deren Breite und Tiefe so an einen Führungszapfen 8, 28 angepaßt ist, daß die Leistungsteilevon den Führungszapfen sicher geführt sind. Die Achsen dieser Führungszapfen sind, bezogen auf die Rotorachse, um 180° zueinander versetzt. Dadurch, daß die Führungszapfen um 180° zueinander verdreht sind, ist ein Massenausgleich gewährleistet, ohne daß dafür zusätzliche Ausgleichsgewichte benötigt werden. Jeder Führungszapfen 8, 28 ist drehfest und exzentrisch mit dem zugeordneten Lagerzapfen 7, 27 verbunden. Jeder Lagerzapfen 7,27 erstreckt sich in eine axiale Ausnehmung in einer Rotorflanke hinein. Die Achsen der Lagerzapfen sind exzentrisch zur Achse der Innenradiung des Gehäusemantels angeordnet, so daß die Rotoren innerhalb des Gehäuses exzentrisch gelagert sind.Each of the rotors 1, 21 has a through bore transverse to its axis of rotation, in each of which a power element 2, 22 is received so as to be displaceable in the longitudinal direction. Each power section 2, 22 has, in the middle of its longitudinal dimension, a guide groove 31 running transversely to the longitudinal section of the power section, the width and depth of which are adapted to a guide pin 8, 28 such that the power parts are securely guided by the guide pin. The axes of these guide pins are offset by 180 ° with respect to the rotor axis. The fact that the guide pins are rotated by 180 ° relative to one another ensures mass balancing without the need for additional balancing weights. Each guide pin 8, 28 is non-rotatably and eccentrically connected to the associated bearing pin 7, 27. Each journal 7.27 extends into an axial recess in a rotor flank. The axes of the trunnions are arranged eccentrically to the axis of the inner radius of the housing shell, so that the rotors are mounted eccentrically within the housing.

Es besteht somit ein Hubeingriff zwischen den exzentrisch im Gehäuse gelagerten Rotoren 1, 21 und den Leistungsteilen 2,22, welche die Rotoren radial durchsetzen. Ferner besteht Schlupfeingriff zwischen dem Gehäusemantel und den Leistungsteilen, welche innerhalb der Rotoren radial zum Gehäusemantel geführt sind. An den einander gegenüberliegenden Enden der Leistungsteile sind Dichtelemente 41 und 42 sowie Ölabstreifringe 43 vorgesehen, so daß je Rotor die beiden Enden der Leistungsteile, die an der Gehäuselauffläche in Anlage sind, mit dem Gehäusemantel zwei Arbeitskammern bilden. Die erfindungsgemäße Maschine besitzt somit je Rotor zwei getrennte Arbeitskammern, d.h. insgesamt 4 Kammern, in denen der ArbeitsprozeB abläuft. Da der Arbeitsprozeß über 720° läuft, d.h. Ansaugen 180°, Verdichten 180°, Arbeiten 180° und Ausstoßen 1800, ist durch die vier Arbeitskammern ein gleichmäßiger Rundlauf gewährleistet.There is thus a meshing engagement between the rotors 1, 21 mounted eccentrically in the housing and the power units 2, 22 which penetrate the rotors radially. There is also a slip engagement between the housing shell and the power parts, which are guided radially to the housing shell within the rotors. On the opposite of each other Lying ends of the power parts, sealing elements 41 and 42 and oil scraper rings 43 are provided, so that the two ends of the power parts, which are in contact with the housing contact surface, form two working chambers with the housing shell for each rotor. The machine according to the invention thus has two separate working chambers for each rotor, ie a total of 4 chambers in which the working process takes place. Since the work process runs over 720 °, ie suction 180 °, compression 180 °, work 180 ° and ejection 180 0 , the four working chambers ensure a constant concentricity.

Bei der Drehung der Rotoren drehen sich diese um ihre eigene Achse, wohingegen die Leistungsteile sich mit Hilfe ihrer Führungsnuten um die jeweiligen Führungszapfen drehen. Bei der Umdrehung der Rotoren um ihre Lagerzapfen bewegen sich die im Querschnitt zylindrischen Leistungsteile um ihre Führungszapfen, wodurch die Leistungsteile derart radial zum Gehäusemantel geführt sind, daß die in den Enden der Leistungsteile angeordneten Dichtelemente ständig in dichtender Gleitanlage an den Gehäuselaufflächen gehalten sind.When the rotors rotate, they rotate around their own axis, whereas the power units rotate around the respective guide pins with the aid of their guide grooves. When the rotors rotate around their bearing journals, the power sections, which are cylindrical in cross section, move around their guide journals, as a result of which the power sections are guided radially to the housing shell in such a way that the sealing elements arranged in the ends of the power sections are constantly held in a sealing slide system on the housing running surfaces.

Die bereits erwähnten Dichtelemente 41, 42 und 43 werden mit Hilfe von Federn an die Rotorbohrung, bzw. die seitliche Gehäuselaufbahn 46, die mittlere Gehäuselaufbahn 47 und die einlaßseitige Gehäuselaufbahn 48 gedrückt.The already mentioned sealing elements 41, 42 and 43 are pressed by means of springs against the rotor bore or the lateral housing race 46, the middle housing race 47 and the inlet-side housing race 48.

In Richtung zum Abtriebskörper 50 befindet sich in jedem Rotor für jede Kammer ein Einlaßkanal 11 und an der Lagerflanschseite ein Auslaßkanal 12. Das Frischgas gelangt durch einen Einlaßregler 53, ein Einlaßgehäuse 49 und den Einlaßkanal 11 in die Kammer. Das Abgas strömt durch den Auslaßkanal 12 aus der Kammer und über einen Auslaßringkanal 13, 33 aus dem Gehäuse 5, 25.In the direction of the driven body 50 there is an inlet channel 11 for each chamber in each rotor and an outlet channel 12 on the bearing flange side. The fresh gas enters the chamber through an inlet regulator 53, an inlet housing 49 and the inlet channel 11. The exhaust gas flows out of the chamber through the outlet channel 12 and out of the housing 5, 25 via an outlet ring channel 13, 33.

Zur Steuerung des Gaswechsels ist auf den Lagerzapfen 7, 27 jeweils ein Abrollkranz 10, 30 vorgesehen, auf welchem jeweils ein Zwischenzahnrad 20, 40 abrollt, welche jeweils eine Steuerwelle 9, 29 antreiben. Diese Steuerwelle betätigt die an sich bekannten Steuerorgane, wie Ventile, Schieber usw. Zu Schmierungs- und Kühlzwecken wird Öl durch Öleintrittsbohrungen 14, 34 zugeführt und mit Hilfe von Bohrungen 32 jeweils einem Ölringkanal 19, 39 zugeführt, von wo es durch Ölaustrittsbohrungen 15, 35 aus den Gehäuseabschnitten 5, 25 heraustritt.To control the gas exchange, a rolling ring 10, 30 is provided on the bearing journal 7, 27, on each of which an intermediate gear wheel 20, 40 rolls, each of which drives a control shaft 9, 29. This control shaft actuates the control elements known per se, such as valves, slides, etc. For lubrication and cooling purposes, oil is supplied through oil inlet bores 14, 34 and, with the aid of bores 32, is supplied to an oil ring channel 19, 39, from where it passes through oil outlet bores 15, 35 emerges from the housing sections 5, 25.

An den Lagerflanschen 4, 24 ist jeweils ein Öldichtring 45 vorgesehen, der einen Ölübertritt vom Triebswerkraum in die Auslaßringkanäle 13, 33 verhindert.An oil sealing ring 45 is provided on each of the bearing flanges 4, 24, which prevents oil passage from the engine compartment into the outlet ring channels 13, 33.

Die in den Kammern erzeugte Drehkraft wird vom Antriebskörper 50 mit Hilfe eines Zahnkranzes 51 auf ein Zwischenzahnrad 55 abgegeben, welches in einem Zwischenradlager 54, das mit dem Einlaßgehäuse 49 verschraubt ist, gelagert ist.The torque generated in the chambers is output from the drive body 50 with the aid of a ring gear 51 to an intermediate gear 55 which is mounted in an intermediate gear bearing 54 which is screwed to the inlet housing 49.

Zur Kühlung sind KÜhlwasserkanäle 16,17,36,37 sowie 52 vorgesehen, obgleich statt dessen auch Luftkühlung möglich ist.Cooling water channels 16, 17, 36, 37 and 52 are provided for cooling, although air cooling is also possible instead.
