In einem Ausführungsbeispiel kann beispielsweise der erste Winkel 5° und der zweite Winkel 20° sein. Auch können der erste Winkel und der zweite Winkel gleich groß sein. Die erste Mittelachse und die zweite Mittelachse können zueinander windschief sein. Weiterhin kann die erste Mittelachse und die dritte Mittelachse eine erste Ebene aufspannen. Die erste Mittelachse und die zweite Mittelachse kann eine zweite Ebene aufspannen. Die erste Ebene und die zweite Ebene können einen Winkel einschließen, der ungeich 0° und ungleich 180° ist. Die erste Ebene und die zweite Ebene können auch deckungsgleich sein.By such an arrangement, both the first gear and the second gear is excited to tumble. For example, in one embodiment, the first angle may be 5 degrees and the second angle may be 20 degrees. Also, the first angle and the second angle can be equal. The first center axis and the second center axis may be skewed to each other. Furthermore, the first central axis and the third central axis span a first plane. The first center axis and the second center axis may span a second level. The first level and the second level may include an angle that is not 0 ° and not equal to 180 °. The first level and the second level can also be congruent.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung spannen die erste Mittelachse und die dritte Mittelachse eine erste Ebene auf und die zweite Mittelachse und die dritte Mittelachse eine zweite Ebene auf. Die erste Ebene und die zweite Ebene stehen aufeinander senkrecht.According to a further embodiment of the invention, the first center axis and the third center axis span a first plane and the second center axis and the third center axis span a second plane. The first level and the second level are perpendicular to each other.
Natürlich können die erste Ebene und die zweite Ebene zueinander jeden beliebigen Winkel einnehmen.Of course, the first level and the second level can take any angle to each other.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung liegen die erste Mittelachse und die zweite Mittelachse in einer gemeinsamen Ebene.According to a further embodiment of the invention, the first center axis and the second center axis lie in a common plane.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung drehen beginnend von der dritten Mittelachse der erste Winkel entgegen dem Uhrzeigersinn und der zweite Winkel im Uhrzeigersinn.According to a further embodiment of the invention rotate starting from the third central axis of the first angle in the counterclockwise direction and the second angle in the clockwise direction.
Durch eine derartige Anordnung kann sichergestellt werden, dass sich die während der Taumelbewegung des beispielsweise zweiten Zahnrades und der Dreh- und Taumelbewegung des ersten Zahnrades entstehenden Momente gegenseitig reduzieren. Durch eine entsprechende Wahl des ersten und zweiten Winkels sowie eine entsprechende erste Masse des ersten Zahnrades und zweite Masse des zweiten Zahnrades ist es möglich, dass sich die während der Drehbewegung der Antriebswelle entstehenden Drehmomente gegenseitig aufheben, so dass das Gehäuse der Drehkolbenmaschine nicht zusätzlich abgestützt werden muss.By such an arrangement can be ensured that reduce the resulting during the tumbling motion of the example, the second gear and the rotational and tumbling motion of the first gear mutually each other. By an appropriate choice of the first and second angle and a corresponding first mass of the first gear and second mass of the second gear, it is possible that the resulting during the rotational movement of the drive shaft torques cancel each other, so that the housing of the rotary piston engine are not additionally supported got to.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung ist mit der Antriebswelle eine zweite Gleitebene fest verbunden. Die zweite Gleitebene und die zweite Mittelachse stehen aufeinander senkrecht. Die erste Gleitebene und das erste Zahnrad sind relativ zueinander drehbar und aneinander verbunden. Die zweite Gleitebene und das zweite Zahnrads sind relativ zueinander drehbar und aneinander verbunden.According to a further embodiment of the invention, a second sliding plane is fixedly connected to the drive shaft. The second sliding plane and the second center axis are perpendicular to each other. The first sliding plane and the first gear are rotatable relative to each other and connected to each other. The second sliding plane and the second gear are rotatable relative to each other and connected to each other.
Durch ein relativ zueinander drehbares Verbinden der zweiten Gleitebene an das zweite Zahnrad kann die Betriebssicherheit der Drehkolbenmaschine erhöht werden, da hierdurch das zweite Zahnrad durch die zweite Gleitebene zwangsweise in eine Taumelbewegung versetzt wird. Durch eine derartige Ausgestaltung kann das erste Zahnrad und das zweite Zahnrad in Verbindung mit der kugelförmigen Innenwandung des Gehäuses zwangsgeführt werden. So können Schwergängigkeiten beim Kämmen der Zahnräder vermieden werden, die sich möglicherweise auf Fertigungstoleranzen der Zahnräder zurückführen lassen können.By a relatively rotatable connection of the second sliding plane to the second gear, the reliability of the rotary piston machine can be increased, as a result, the second gear through the second sliding plane forcibly put into a tumbling motion. By such a configuration, the first gear and the second gear can be constrained in conjunction with the spherical inner wall of the housing. Thus, binding when combing the gears can be avoided, which can possibly be attributed to manufacturing tolerances of the gears.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung schneiden sich die erste Mittelachse, die zweite Mittelachse und die dritte Mittelachse in einem gemeinsamen Punkt, wobei der gemeinsame Punkt Mittelpunkt eines Durchmessers der Innenwandung ist.According to a further embodiment of the invention, the first center axis, the second center axis and the third center axis intersect at a common point, the common point being the center of a diameter of the inner wall.
Natürlich schneidet auch ein Durchmesser der kugelig ausgebildeten Auflagefläche die dritte Mittelachse in dem gemeinsamen Punkt. Hierdurch kann sichergestellt werden, dass zwischen den einzelnen Teilen keine translatorischen Bewegungen erfolgen, die zu einem höheren Verschleiß führen können.Of course, a diameter of the spherical bearing surface also cuts the third central axis in the common point. In this way it can be ensured that no translational movements take place between the individual parts, which can lead to higher wear.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung schneiden die erste Gleitebene und die zweite Gleitebene den gemeinsamen Punkt.According to a further embodiment of the invention, the first sliding plane and the second sliding plane intersect the common point.
Hierdurch kann bewirkt werden, dass sich die Gleitebene und das zugehörige Zahnrad aneinander in einer Kreisbahn bewegen, jedoch mit unterschiedlichen Geschwindigkeiten. Insbesondere, wenn zwischen der Gleitebene und dem zugehörigen Zahnrad beispielsweise ein Wälzlager, beispielsweise ein Axiallager, angeordnet ist, wird die Haltbarkeit der Drehkolbenmaschine durch eine Vermeidung einer translatorischen Bewegung von dem Zahnrad und der Gleitebene verlängert.This may cause the slip plane and the associated gear to move together in a circular path, but at different speeds. In particular, if between the slip plane and the associated gear, for example, a roller bearing, such as a thrust bearing is arranged, the durability of the rotary piston machine is extended by avoiding a translational movement of the gear and the sliding plane.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung schneiden die erste Gleitebene und/oder die zweite Gleitebene den gemeinsamen Punkt nicht.According to another exemplary embodiment of the invention, the first sliding plane and / or the second sliding plane do not intersect the common point.
Hierdurch entsteht zwischen der Gleitebene und dem zugehörigen Zahnrad zusätzlich zur rotatorischen Bewegung auch eine translatorische Bewegung. Durch die translatorische Bewegung kann eine Riefenbildung an der Gleitebene, respektive an dem Zahnrad, verhindert werden, da durch die unterschiedlichen Drehgeschwindigkeiten von Zahnrad und zugehöriger Gleitebene erst nach einer vorbestimmten Umgrehungszahl das Zahnrad und die zugehörige Gleitebene ihre Ausgangsposition wieder einnehmen.As a result, in addition to the rotational movement, a translatory movement is also created between the sliding plane and the associated toothed wheel. Due to the translational movement, a scoring at the sliding plane, respectively on the gear, can be prevented, since by the different rotational speeds of the gear and associated slip plane only after a predetermined rotational speed, the gear and the associated slip plane resume their starting position.
Gemäß einem weiteren Ausgestaltungsbeispiel ist das zweite Zahnrad drehfest an das Gehäuse gekoppelt. An einer Außenwandung des zweiten Zahnrades ist ein Zapfen fest verbunden. Der Zapfen ist in einer nutförmigen Vertiefung in der Innenwandung geführt, wobei die Vertiefung kreisförmig ausgebildet ist.According to a further exemplary embodiment, the second gear is non-rotatably coupled to the housing. On an outer wall of the second gear, a pin is firmly connected. The pin is guided in a groove-shaped recess in the inner wall, wherein the recess is circular.
Aufgrund der auf das zweite Zahnrad während des Verdichtungsprozesses auf die Zähne der Zahnräder wirkenden Kräfte wird der Zapfen, der in der Regel kreiszylinderförmig ausgebildet ist, gegen die kreisförmige Vertiefung gedrückt. Natürlich kann die Vertiefung auch als kreisförmige Nut ausgebildet sein, so dass diese Nut als Kulisse für den Zapfen dienen kann. Der Zapfen in Verbindung mit der kreisförmigen Vertiefung kann als Fixierung des zweiten Zahnrades an das Gehäuse ausgebildet, so dass hierdurch eine Rotationsbewegung des zweiten Zahnrades verhindert ist. Die kreisförmige Vertiefung in Verbindung mit dem Zapfen kann also lediglich die Taumelbewegung des zweiten Zahnrads sicherstellen.Due to the force acting on the teeth of the gears during the compression process on the second gear during the compression of the forces of the pin, which is usually formed circular cylindrical, pressed against the circular recess. Of course, the recess may also be formed as a circular groove, so that this groove can serve as a backdrop for the pin. The pin in conjunction with the circular recess can be formed as a fixation of the second gear to the housing, so that in this way a rotational movement of the second gear is prevented. The circular recess in conjunction with the pin can thus ensure only the wobbling movement of the second gear.
Gemäß einem weiteren Ausgestaltungsbeispiel ist das erste Zahnrad an das Gehäuse drehfest gekoppelt.According to a further embodiment, the first gear is rotatably coupled to the housing.
Eine Fixierung des ersten Zahnrades an dem Gehäuse kann beispielsweise mittels eines an dem ersten Zahnrad in radialer Richtung ragenden Zapfens in Verbindung mit einem an der Innenwandung, respektive dem Gehäuse, ausgebildeten Nut erfolgen. Hierdurch kann zwar das erste Zahnrad taumeln, sich jedoch nicht drehen. Bei einer derartigen Ausgestaltung wird in der Regel das zweite Zahnrad ebenfalls taumeln und sich in der Regel auch drehen.A fixation of the first gear on the housing, for example, by means of a protruding on the first gear in the radial direction pin in conjunction with a formed on the inner wall, respectively the housing groove formed. Although this may wobble the first gear, but not turn. In such a configuration, the second gear will usually also tumble and usually turn as well.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung erstreckt sich der Zapfen entlang einer vierten Mittelachse..According to a further embodiment of the invention, the pin extends along a fourth central axis.
Durch eine derartige Ausgestaltung des Zapfens benötigt die kreisförmige Vertiefung in der Innenwandung keinen Hinterschnitt. Somit lassen sich sowohl der Zapfen als auch die Innenwandung des Gehäuses als Kunststoffspritzteil preisgünstig herstellen.By such a configuration of the pin, the circular recess in the inner wall requires no undercut. Thus, both the pin and the inner wall of the housing can be produced inexpensively as a plastic injection molded part.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung weist wenigstens eine Komponente aus der Gruppe von wenigstens ein erster Zahn und wenigstens ein zweiter Zahn der Drehkolbenmaschine eine Aussparung auf, so dass in einem vorbestimmten Drehwinkelbereich der wenigstens einen Komponente eine Überschneidung mit dem Zufluss und/oder dem Abfluss stattfindet.According to a further embodiment of the invention, at least one component from the group of at least one first tooth and at least one second tooth of the rotary piston machine has a recess, so that in a predetermined rotation angle range of the at least one component, an overlap with the inflow and / or outflow takes place ,
Durch eine derartige Ausgestaltung kann der Zeitabschnitt, in dem das Medium dem Arbeitsraum zugeführt oder das Medium dem Arbeitsraum entnommen wird, vergrößert werden. Damit kann ein höherer Füllgrad des Arbeitsraumes mit dem Medium realisiert werden. Die Aussparung kann an einer Zahnflanke oder an beiden Zahnflanken eines Zahnes ausgebildet sein. Auch können die Aussparungen an den beiden Zahnflanken voneinander unterschiedlich sein. Auch können die einzelnen Zuflüsse und/oder Abflüsse miteinander verbunden sein. Auch können Zuflüsse mit Abflüssen verbunden sein, um beispielsweise durch eine derartige Drehkolbenmaschine die zu erzielenden Drücke zu erhöhen. Natürlich können dann die Zuflüsse und Abflüsse mittels Ventilen, insbesondere Magnetventilen, gesteuert sein.By such a configuration, the time period in which the medium is supplied to the working space or the medium is removed from the working space can be increased. This allows a higher degree of filling of the working space can be realized with the medium. The recess may be formed on a tooth flank or on both tooth flanks of a tooth. Also, the recesses may be different from each other at the two tooth flanks. Also, the individual tributaries and / or outflows can be interconnected. Also, inflows may be associated with drains to increase, for example, by such a rotary engine, the pressures to be achieved. Of course, then the inflows and outflows can be controlled by means of valves, in particular solenoid valves.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung weist wenigstens eine Komponente aus der Gruppe von erster Zahn, zweiter Zahn, erste Gleitebene, zweite Gleitebene, Innenwandung und Außenwandung eine Vertiefung zur Aufnahme von Schmiermittel auf.According to a further exemplary embodiment of the invention, at least one component from the group of first tooth, second tooth, first sliding plane, second sliding plane, inner wall and outer wall has a recess for receiving lubricant.
Durch Schmiermittel kann die Reibung der einzelnen Komponenten untereinander reduziert werden, so dass hierdurch die theoretische Lebensdauer der Drehkolbenmaschine verlängert werden kann.Through lubricant, the friction of the individual components can be reduced with each other, so that in this way the theoretical life of the rotary piston engine can be extended.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung ist die erste Verzahnung und die zweite Verzahnung ausgewählt aus der Gruppe von Schrägverzahnung, Evolventenverzahnung, Zykloidenverzahnung und Pfeilverzahnung.According to another exemplary embodiment of the invention, the first toothing and the second toothing are selected from the group of helical toothing, involute toothing, cycloidal toothing and helical toothing.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung kann ein Lagerelement zwischen der Gleitebene und dem zugehörigen Zahnrad als geschmiertes, hydraulisch oder pneumatisch unterstütztes Gleitlager ausgestaltet sein. Ferner kann das Lagerelement als Wälzlager, beispielsweise als Rollenlager oder sonstiges Lager nach dem Stand der Technik ausgebildet sein.According to a further embodiment of the invention, a bearing element between the sliding plane and the associated gear as lubricated, hydraulically or pneumatically supported slide bearing be configured. Furthermore, the bearing element can be designed as a roller bearing, for example as a roller bearing or other bearing according to the prior art.
Gemäß einem weiteren Ausgestaltungsbeispiel der Erfindung kann die im vorhergehenden beschriebenen Drehkolbenmaschine als Getriebe genutzt werden.According to a further embodiment of the invention, the rotary piston machine described above can be used as a transmission.

Einem Fachmann ist hierbei klar, dass die einzelnen beschriebenen Merkmale auf verschiedene Weise miteinander kombiniert werden können, um so auch zu anderen Ausgestaltungen der Erfindung zu gelangen.It should be noted that thoughts on the invention are described herein in the context of a rotary piston engine. It will be clear to a person skilled in the art that the individual features described can be combined with one another in various ways so as to arrive at other embodiments of the invention.
