Description
Drehkolbenverdichter mit sichelförmigem Arbeitsraum und in der Kolbentrommel verschiebbaren Kolben, die sich gegen einen mitumlaufenden Zylindermantel legen Die Erfindung bezieht sich auf einen Drehkolbenverdichter, der in Verbindung mit einer Brennkraftmaschine benutzt werden kann, besonders in dem Fall, wo die Maschine nach dem Zweitaktsystem arbeitet.Rotary piston compressor with sickle-shaped working space and in the piston drum displaceable pistons that lie against a rotating cylinder jacket The invention relates to a rotary lobe compressor that is used in conjunction with an internal combustion engine can be used, especially in the case where the engine works according to the two-stroke system.
Der Drehkolbenverdichter gemäß der Erfindung ist mit in einer Kolbentrommel verschiebbaren Kolben versehen, die sich infolge der Wirkung der Fliehkraft oder durch Federkraft gegen einen durch die Reibung mitgenommenen Zylindermantel legen.The rotary piston compressor according to the invention is in a piston drum slidable piston provided, which is due to the effect of centrifugal force or Place by spring force against a cylinder jacket that is dragged along by the friction.
Zweck der Erfindung ist es, eine zwangsläufige Verbindung zwischen der Kolbentrommel und dem Zylindermantel herzustellen, der sich konzentrisch zum Gehäuse mit der gleichen Geschwindigkeit wie die Kolbentrommel dreht.The purpose of the invention is to create an inevitable connection between to produce the piston drum and the cylinder jacket, which is concentric to the Housing rotates at the same speed as the piston barrel.
Es ist bekannt, eine solche Verbindung entweder durch Zahnräder oder mittels eines in Zapfen gelagerten Kulissensteins auf dem beweglichen Teil herzustellen, der in einem Schlitzrahmen gleitet, der selbst als Kulissenstein in den Führungsbahnen des Aufnahmestückes gleitet, oder auch durch eine Vorrichtung mit in Zapfen gelagerten Führungsrollen auf dem beweglichen Teil, die auf der Innenfläche ringförmiger Schlitze auf einem Teil des Aufnahmestückes laufen.It is known to have such a connection either through gears or to be produced on the moving part by means of a sliding block mounted in journals, which slides in a slot frame, which itself acts as a sliding block in the guideways of the receiving piece slides, or by a device with mounted in pegs Guide rollers on the moving part, which on the inner surface of annular slots run on part of the recording piece.
Die Ausführung mit Zahnradgetrieben ist umständlich und kostspielig.The design with gear drives is cumbersome and expensive.
Bei der zweiten Anordnung ist der Druck zwischen Kulissenstein und Geradführung bei den verschiedenen Stellungen dieser Teile nicht gleichbleibend, wodurch ungleichmäßige Abnutzung, zu großes Spiel, Schwingungen und Lärm bei hohen Geschwindigkeiten verursacht werden.In the second arrangement, the pressure is between sliding block and Straight guidance not constant in the various positions of these parts, causing uneven wear, excessive play, vibration and noise at high levels Speeds are caused.
Dieselbe Beobachtung wurde bei dem dritten System gemacht, bei dem sich die Führungsrollen theoretisch nach einer Erzeugenden berühren, wodurch erhebliche örtliche Drucke und übermäßige Abnutzung entstehen.The same observation was made with the third system, the Theoretically, the leadership roles touch each other after a generative, whereby considerable local prints and excessive wear and tear arise.
Alle diese Anordnungen verursachen überdies große Schwierigkeiten hinsichtlich der Schmierung.Moreover, all of these arrangements cause great difficulties in terms of lubrication.
Gemäß der Erfindung wird der Zylindermantel mit der Kolbentrommel durch eine Anzahl Lenker verbunden, deren Länge der Größe der Exzentrizität der Kolbentrommel zum Zylindermantel entspricht. Die Lenker sind einerseits auf Zapfen gelenkartig angeordnet, die einen Teil der Kolbentrommel bilden, anderseits auf Zapfen, die am Zylindermantel angeordnet sind.According to the invention, the cylinder jacket with the piston drum connected by a number of links, the length of which is the size of the eccentricity of the Piston drum corresponds to the cylinder jacket. The handlebars are on the one hand on pegs articulated, which form part of the piston drum, on the other hand Pins, which are arranged on the cylinder jacket.
Die Vorrichtung nach der Erfindung vermeidet die oben angeführten Nachteile hinsichtlich der Abnutzung, des Lärms, der Schwingungen und der Schmierung dadurch, daß die sich reibenden Teile zylindrisch sind und den gleichen Durchmesser haben.The device according to the invention avoids those mentioned above Disadvantages in terms of wear, noise, vibrations and lubrication in that the rubbing parts are cylindrical and of the same diameter to have.
Ferner wird der Zylindermantel, der sich konzentrisch zum Gehäuse dreht, auf der einen Seite von einer Flanschenscheibe gehalten, die von einem Kugellager getragen wird, und auf der anderen Seite von einer Flanschenscheibe, die von einem Rollenlager getragen wird.Furthermore, the cylinder jacket, which is concentric to the housing turns on the one side held by a flange washer, which is supported by a ball bearing, and on the other side by a flange washer, which is supported by a roller bearing.
Diese letzte Anordnung weist den großen Vorteil auf, daß sie eine Verschiebung der Kolbentrommel durch Wärmeausdehnung gestattet, während diese Verschiebung bei Anwendung von zwei Kugellagern ein Klemmen der Kugeln verursachen würde.This last arrangement has the great advantage that it is a Displacement of the piston barrel by thermal expansion is allowed during this displacement would cause the balls to jam when using two ball bearings.
Eine Ausführungsform der Erfindung ist in den beiliegenden Zeichnungen beispielsweise dargestellt.An embodiment of the invention is in the accompanying drawings for example shown.
Fig. i ist ein Querschnitt durch den Verdichter.Fig. I is a cross section through the compressor.
Fig. 2 ist eine Ansicht der Fig. i von links und zeigt die Lenker und die zwangsläufige Verbindung zwischen der Kolbentrommel und dem mitumlaufenden Zylindermantel des Verdichters.Figure 2 is a left side view of Figure i showing the handlebars and the positive connection between the piston drum and the rotating one Cylinder jacket of the compressor.
Fig. 3 ist ein Querschnitt gemäß Linie 1-I der Fig. i.Figure 3 is a cross-section on line 1-I of Figure i.
Das Gehäuse 21 des Drehkolbenverdichters umschließt einen sich drehenden Zylindermantel 22: Dieser Mantel 22 wird auf der einen Seite von einer Flanschenscheibe 23 gestützt, die selbst von einem Kugellager 24 getragen wird, und auf der anderen Seite von einer zweiten Flanschenscheibe 25 mit einem Rollenlager 26. Die Kolbentrommel 27 wird auf der einen Seite von einer Flanschenscheibe 28 eingefaßt, die eine Achse trägt, die in die Nabe 29 eines Rollenlagers 30 eingesetzt ist. Auf der anderen Seite wird die Kolbentrommel 27 von einer Flanschenscheibe 3 i gehalten, deren Achse in die Nabe eines Ritzels 32 eingesetzt ist, die mit dem Innenring eines die Kolbentrommel 27 tragenden Rollenlagers 33 aus einem Stück besteht.The housing 21 of the rotary piston compressor encloses a rotating cylinder jacket 22: This jacket 22 is supported on one side by a flange washer 23, which is itself supported by a ball bearing 24, and on the other side by a second flange washer 25 with a roller bearing 26. The piston drum 27 is framed on one side by a flange disk 28 which carries an axle which is inserted into the hub 29 of a roller bearing 30. On the other hand, the piston drum 27 is held by a flange disk 3 i, the axis of which is inserted into the hub of a pinion 32 which is made in one piece with the inner ring of a roller bearing 33 carrying the piston drum 27.
In Fig.3 ist die Kolbentrommel 27, die mit radial verlaufenden Schlitzen 27a versehen ist, im Schnitt dargestellt. In den Schlitzen sind mit geringer Reibung die Kolben 39 eingepaßt, die mit der Kolbentrommel 27 und dem Zylindermante122 die Arbeitsräume 40 abgrenzen. Die Arbeitsräume 40 werden im Betriebe, wenn die Kolbentrommel in Richtung des Pfeiles x umläuft, mittels der Ausschnitte 22a einerseits mit der Zuführungsleitung Zia und anderseits mit der Auspuffleitung i 9 verbunden, die beispielsweise zum Einlaß 7 eines Zylinders eines Zweitaktmotors führt. In dem dargestellten Ausführungsbeispiel werden die Kolben 39 infolge der Fliehkraft gegen den 7-ylindermante122 gepreßt. Es versteht sich von -selbst, daß man, ohne von -dem Erfindungsgedanken abzuweichen, in den Schlitzen 27a auch Federn anordnen kann, die auf die Kolben 39 in demselben Sinne wie die Fliehkraft wirken.In Figure 3, the piston drum 27, which is provided with radially extending slots 27a, is shown in section. The pistons 39, which delimit the working spaces 40 with the piston drum 27 and the cylinder skirt 122, are fitted into the slots with little friction. When the piston drum rotates in the direction of the arrow x, the working spaces 40 are connected by means of the cutouts 22a on the one hand to the supply line Zia and on the other hand to the exhaust line i 9, which leads, for example, to the inlet 7 of a cylinder of a two-stroke engine. In the illustrated embodiment, the pistons 39 are pressed against the 7-ylindermante122 as a result of the centrifugal force. It goes without saying that, without deviating from the inventive concept, springs can also be arranged in the slots 27a, which act on the pistons 39 in the same sense as the centrifugal force.
Der Zylindermantel22 dreht sich also um eine Achse 34 und die Kolbentrommel 27 um eine Achse 35. Die Nabe 29 ist an ihrer Stirnseite mit sechs Zapfen 36 versehen, während die Flanschenscheibe 25, die in dem Rollenlager 26 läuft, in gleicher Weise auf ihrer vorderen Fläche sechs Zapfen 37 trägt. Die Zapfen 36 der Nabe 29 stehen mit den Zapfen 37 der Flanschenscheibe 25 durch sechs kleine Lenker 38 in Verbindung. Bei der Drehung der Kolbentrommel 27 wird daher der Zylindermante122 mit der gleichen Geschwindigkeit wie die Kolbentrommel 27 zwangsläufig mitgenommen.The cylinder jacket 22 therefore rotates about an axis 34 and the piston drum 27 about an axis 35. The hub 29 is provided with six pins 36 on its end face, while the flange disk 25, which runs in the roller bearing 26, is similarly on its front surface six pins 37 carries. The pins 36 of the hub 29 are connected to the pins 37 of the flange washer 25 by six small links 38. When the piston drum 27 rotates, the cylinder surface 122 is therefore inevitably entrained at the same speed as the piston drum 27.
Die Flanschenscheibe der Nabe 29, die die Zapfen 36 trägt, hat an ihrem Umfang einen Ölfang 29a. Dieser Ölfang 29a soll das Öl zurückhalten, das aus dem Rollenlager 3o austritt und durch die Zentrifugalkraft abgeschleudert wird. Vom Boden des Ölfanges 29a gehen Leitungen aus, die in Kanälen enden, die die Zapfen 36 durchziehen, deren Schmierung in bekannter Weise durch Schmiernuten bewirkt wird. Zwecks Schmierung der Zapfen 37 der Flanschenscheibe 25, die mit dem Zylindermante122 fest verbunden ist, sind die Lenker 38 mit Kanälen versehen, in denen das Ö1 läuft, das infolge der Fliehkraft in Schmieröffnungen geschlendert wird, die sich vorteilhaft in den Lenkerköpfen befinden, die sich auf den Zapfen 37 drehen.The flange washer of the hub 29, which carries the pin 36, has on its scope an oil trap 29a. This oil trap 29a is intended to hold back the oil that comes out the roller bearing 3o emerges and is thrown off by the centrifugal force. Lines extend from the bottom of the oil trap 29a and end in channels that form the pegs 36 pull through, the lubrication of which is effected in a known manner by means of lubrication grooves. For the purpose of lubricating the pin 37 of the flange washer 25, which is connected to the cylinder mantle 122 is firmly connected, the handlebars 38 are provided with channels in which the oil runs, which is strolled into lubrication openings due to the centrifugal force, which is advantageous are in the handlebar heads, which turn on the pin 37.
