Abstract
Description
Die Erfindung betrifft den Massenausgleich für eine Drehkolbenmaschine, die eine in einem Gehäuse gelagerte Antriebswelle mit einem an dieser angebrachten Exzenter und einen an dem kreisförmigen Exzenter gelagerten Drehkolben umfasst, wobei der Drehkolben mindestens ein Paar an seinem Umfang ausgebildeter konvexer und konkaver Kolbenflächen aufweist, die während der exzentrischen Kolbenbewegung mit mindestens einem an der Innenwand des Gehäuses ausgebildeten zugehörigen Paar konvexer und konkaver Zylinderflächen mindestens eine Zylinderkammer mit sich änderndem Volumen bilden.The Invention relates to mass balance for a rotary engine, the one mounted in a housing drive shaft with a on this attached eccentric and one on the circular Eccentric bearing mounted rotary piston, wherein the rotary piston at least a pair of convex and concave piston surfaces formed on its periphery that is during the eccentric piston movement with at least one formed on the inner wall of the housing associated pair of convex and concave cylindrical surfaces at least one cylinder chamber with a changing volume form.

Der Erfindung liegt die Aufgabe zugrunde, eine Drehkolbenmaschine mit geringer Baugröße und niedrigem Gewicht anzugeben, die zudem mit vermindertem Kostenaufwand hergestellt werden kann.Of the Invention is based on the object, a rotary piston machine with specify small size and low weight, which can also be produced at a reduced cost.
Erfindungsgemäß wird die Aufgabe mit einer gemäß den Merkmalen des Patentanspruchs 1 ausgebildeten Drehkolbenmaschine gelöst. Zweckmäßige und vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.According to the invention the task with a according to the characteristics of Patent claim 1 trained rotary engine solved. Advantageous and advantageous embodiments of Invention will become apparent from the dependent claims.
Kern der Erfindung ist ein negativer Massenausgleich an den Antriebsübertragungselementen für den Drehkolben, derart, dass mindestens in der Antriebswelle oder dem mit dieser verbundenen Exzenter, und zwar in dem zwischen der Mittelachse und dem distalen – am weitesten entfernten – Rand des Exzenters mindestens ein Massenausgleichshohlräume ausgebildet ist. Durch diesen negativen Massenausgleich ist die Drehkolbenmaschine bei verminderten Material- und Herstellungskosten gewichts- und platzsparend ausgebildet.core The invention is a negative mass balance on the drive transmission elements for the rotary piston, such that at least in the drive shaft or the associated with this eccentric, in between the central axis and the distal - farthest - edge of the eccentric at least one mass balancing cavities is trained. This negative mass balance is the Rotary piston machine with reduced material and manufacturing costs designed to save weight and space.
Die Hohlräume können geschlossen sein oder offen in Form von Durchgangsbohrungen, Sacklochbohrungen, Ausnehmungen oder Öffnungen ausgeführt sein. Die Querschnittsfläche der Massenausgleichshohlräume ist im Wesentlichen symmetrisch zu einer zwischen der Mittelachse und dem distalen Rand des Exzenters verlaufenden gedachten Linie.The Cavities may be closed or open in Form of through holes, blind holes, recesses or openings performed be. The cross-sectional area of the mass balancing cavities is substantially symmetrical to one between the central axis and the distal edge of the eccentric extending imaginary line.
In weiterer Ausbildung der Erfindung ist eine mit der Antriebswelle verbundene runde Lagerscheibe so ausgebildet, das in dieser ein Massenausgleichshohlraum untergebracht werden kann.In Another embodiment of the invention is one with the drive shaft connected round bearing disc designed so that in this one Mass compensation cavity can be accommodated.
