Description
Brennkraftmaschine mit hin und her gehendem und sich drehendem Kolben Die Erfindung bezieht sich auf Brennkraftmaschinen, bei denen der Kolben zum unmittelbaren Antrieb der Arbeitswelle neben seiner hin und her gehenden Bewegung zugleich eine Drehbewegung ausführt, die auf die anzutreibende Welle übertragen wird. Zu diesem Zweck ist in bekannter Weise in die zylindrische Außenfläche des Kolbens eine um diesen herum verlaufende Kurvennut eingeschnitten, in welche am Zylinder befestigte Führungszapfen eingreifen.Internal combustion engine with reciprocating and rotating pistons The invention relates to internal combustion engines, in which the piston to the immediate Drive of the working shaft in addition to its reciprocating motion at the same time Performs rotary movement that is transmitted to the shaft to be driven. To this The purpose is in a known manner in the cylindrical outer surface of the piston This curved groove running around cut into which attached to the cylinder Engage the guide pin.
Die bisher bekannten Ausführungsformen dieser Art von Verbrennungskraftmaschinen konnten jedoch nicht befriedigen, da wegen ihrer ungünstigen Schmierungsverhältnisse die an den gleitenden Teilen, insbesondere an den Führungsflächen der Kurvennut auftretenden Reibungsverluste zu groß waren. Bei einer Zuführung des öles von der Außenseite des Zylinders, wie sie bekannte Ausführungen zeigen, genügt die ölmenge für die Schmierung und Kühlung nicht. Gegenüber den seitherigen Ausführungsformen, bei denen die um die zylindrische Wandfläche des Kolbens verlaufende Nut nach der Kolbenmitte hin geschlossen ist, wird gemäß der Erfindung die Kurvenführung durch einen in der Kolbenwand befindlichen Schlitz gebildet, der diese in zwei Teile trennt und eine reichliche, unmittelbare ölzufuhr vom Kolbeninnern her zu den zu schmierenden und zu kühlenden Teilen gestattet. Die durch den Führungsschlitz voneinander getrennten -beiden Hälften der Kolbenwand werden durch zwei im Innern des Kolbens befindliche Verbindungsrippen zusammengehalten, in denen sich Längsschlitze für die Aufnahme der Enden eines Keiles befinden, der mit der Welle fest verbunden ist. Diese Schlitze in den Verbindungsrippen dienen gleichzeitig dazu, von den beiden Bewegungen des Kolbens, nämlich der drehenden und der hin und her gehenden, allein die Drehbewegung auf die Arbeitswelle zu Übertragen.The previously known embodiments of this type of internal combustion engine could not satisfy, however, because of their unfavorable lubrication conditions those on the sliding parts, especially on the guide surfaces of the cam groove occurring frictional losses were too great. When the oil is supplied from the Outside of the cylinder, as shown in known designs, the amount of oil is sufficient for lubrication and cooling not. Compared to the previous embodiments, in which the groove running around the cylindrical wall surface of the piston according to the Piston center is closed, the curve guide is according to the invention a slot located in the piston wall is formed which separates it into two parts and an abundant, direct oil supply from the inside of the piston to the ones to be lubricated and parts to be cooled. The separated by the guide slot -both halves of the piston wall are replaced by two located inside the piston Connecting ribs held together, in which there are longitudinal slots for the inclusion the ends of a wedge that is firmly connected to the shaft. These slots in the connecting ribs serve at the same time to benefit from the two movements of the Pistons, namely the rotating and the reciprocating, only the rotary motion to be transferred to the working shaft.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.
Abb. i zeigt einen Längsschnitt durch eine zweizylindrige Bremskraftmaschine mit hin und her gehenden und zugleich sich drehenden Kolben; Abb. 2 ist ein Querschnitt durch einen der Zylinder, und Abb. 3 stellt einen Längsschnitt durch einen Kolben dar.Fig. I shows a longitudinal section through a two-cylinder brake engine with pistons moving back and forth and rotating at the same time; Fig. 2 is a cross section through one of the cylinders, and Fig. 3 shows a longitudinal section through a piston represent.
Jeder der beiden Zylinder der dargestelltem Maschine besteht aus den beiden durch Flanschen verbundenen Hälften io und i i und ist nach außen durch die Zylinderböden i q. abgeschlossen, in denen sich kreisförmige oder sektorförmige Ein- und Auslaßöffnungen 15, 16 befinden.. Die Arbeits-,velle 17 hat die gleiche Achse wie die Zylinder und ist in den Zylinderböden geführt. In jedem Zylinder befindet sich ein Kolben i g, der auf beiden Seiten mit Böden i9 und 2o versehen ist, die zusammen mit den gegenüberliegenden Zylinderböden Verbrennungskammern 21, 22 einschließen. Der Kolben jedes Zylinders führt im Betriebe eine hin und her gehende und zugleich eine drehende Bewegung aus, wobei nur die Drehbewegung auf die Arbeitswelle 17 übertragen wird. Zu diesem Zweck ist in der zylindrischen Wand des Kolbens ein ringsherum sich erstreckender ein oder mehriene Male in axialer Richtung hin und her verlaufender Führungsschlitz 26 angebracht. Die beiden durch diesen Schlitz voneinander getrennten Kolbenhälften 8 und 9 sind durch zwei besondere zwischen den Kolbenböden i9, 2o liegende Rippen 25 miteinander verbunden. Der Kolben jedes Zylinders steht mit der Welle 17 durch einen Querkeil 23 in Verbindung, der fest in der Welle sitzt und mit seinen äußeren Enden in Längsschlitze 24 der Rippen 25 eingreift.Each of the two cylinders of the machine shown consists of the two halves io and i i connected by flanges and is outward through the Cylinder bottoms i q. completed in which are circular or sector-shaped Inlet and outlet openings 15, 16 are located .. The working, shaft 17 has the same Axis like the cylinder and is guided in the cylinder base. Located in each cylinder a piston i g, which is provided on both sides with bottoms i9 and 2o, the together with the opposing cylinder bottoms include combustion chambers 21,22. Of the Pistons of each cylinder in operation have a reciprocating and at the same time one rotary motion, only the rotary motion being transmitted to the working shaft 17 will. For this purpose, there is a around itself in the cylindrical wall of the piston extending back and forth one or more times in the axial direction Guide slot 26 attached. The two separated from each other by this slot Piston halves 8 and 9 are by two special between the piston heads i9, 2o lying ribs 25 connected to one another. The piston of each cylinder stands with the Shaft 17 by a transverse key 23 in connection, which sits firmly in the shaft and engages with its outer ends in longitudinal slots 24 of the ribs 25.
Auf der Innenwand der Zylinder befinden sich an entgegengesetzten Punkten der Verbindungsstellen ihrer Teile i o und i i kegelförmige Führungsrollen 3o, die auf je einem in Führungen 28 einstellbaren Schlitten 29 befestigt sind und in den Führungsschlitz 26 des Kolbens greifen. Die Einstellung der Schlitten 29 und damit der Führungsrollen 3o erfolgt durch Kopfschrauben 31, die durch Deckelplatten 32 gehen und durch Gegenmuttern 33 gesichert sind. Die Führungsrollen, deren konische Flächen auf entsprechend abgeschrägten Stirnflächen des Schlitzes 26 laufen, können demnach bei Abnutzung nachgestellt werden.On the inside wall of the cylinders are on opposite sides Points of the connection points of their parts i o and i i conical guide rollers 3o, which are each attached to a slide 29 adjustable in guides 28 and engage in the guide slot 26 of the piston. Adjusting the slide 29 and thus the guide rollers 3o is carried out by cap screws 31, which by cover plates 32 go and are secured by lock nuts 33. The guide rollers, their conical Surfaces run on correspondingly beveled faces of the slot 26 can can therefore be readjusted when worn.
In starrer Verbindung mit der Welle 17 und in enger Berührung mit der Innenwandung der Zylinderböden sind die Ventilscheiben 36 angeordnet, von denen jede mit .einer Durchgangsöffnung 37 versehen ist, die sich bei der Drehung mit den Einlaß- bzw. Auslaßöffnungen 15, 16 im Zylinderboden deckt. Diese Ein- und Auslaßöffnungen stehen mit den Ansaug- bzw. Auspuffrohren 34, 35 in Verbindung. Die Zündkerzen 38 sitzen an den Zylinderenden.In rigid connection with the shaft 17 and in close contact with it the inner wall of the cylinder bases, the valve disks 36 are arranged, of which each with .einer passage opening 37 is provided, which during rotation with covers the inlet and outlet openings 15, 16 in the cylinder base. These inlet and outlet openings are in communication with the intake and exhaust pipes 34, 35. The spark plugs 38 sit at the cylinder ends.
