in der
Der Nachteil einer solchen Taumellageranordnung liegt darin begründet, dass deren Rotationsgeschwindigkeit durch den verwendeten Motor bestimmt ist. Da schnelldrehende Motoren oftmals billiger als langsamdrehende sind, werden diese bevorzugt verwendet, so dass bei bestimmten Anwendungsfällen die Rotationsgeschwindigkeit der Taumellageranordnung zu hoch ist. Diese versucht man durch Untersetzungsgetriebe herabzusetzen.Of the Disadvantage of such a swash bearing arrangement is due to the fact that whose rotational speed is determined by the motor used is. Because fast-moving engines are often cheaper than slow-moving ones These are preferably used so that in certain applications the Rotation speed of the swash bearing assembly is too high. These one tries to reduce by reduction gear.

Zusammenfassung der ErfindungSummary the invention
Ausgehend von den bekannten Nachteilen des Standes der Technik liegt daher der Erfindung die Aufgabe zugrunde, eine Untersetzung für ein Taumelscheibengetriebe bereitzustellen, die einfach aufgebaut und sich kostengünstig fertigen lässt.outgoing from the known disadvantages of the prior art is therefore The invention is based on the object, a reduction for a swash plate gear provide that are simple and inexpensive to manufacture leaves.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 in Verbindung mit dessen Oberbegriff dadurch gelöst, dass der Taumelkörper wenigstens an einem Teilbereich seiner inneren oder äußeren Mantelfläche kraft- oder formschlüssig durch ein Antriebselement in Rotation versetzt ist, dessen Durchmesser kleiner als der Durchmesser des Taumelkörpers in diesem Teilbereich ist.According to the invention this Task according to the characterizing part of claim 1 in conjunction solved with the preamble in that the tumbling body at least at a partial area of its inner or outer circumferential surface or positive fit is set in rotation by a drive element whose diameter smaller than the diameter of the wobble body in this section is.
Der entscheidende Vorteil dieser erfindungsgemäßen Untersetzung eines Taumelscheibengetriebes liegt darin, dass durch die unmittelbare Anlage von Taumelkörper und Antriebselement radialer und auch axialer Bauraum einsparbar ist. So sind die nach dem bisherigen Stand der Technik erforderlichen Zahnriemen und Triebscheiben nicht mehr erforderlich. Ein weiterer Vorteil liegt darin, dass durch die unmittelbare Anlage von Taumelkörper und Antriebselement auftretende Schwingungen wirkungsvoll gedämpft werden kön nen. Es ist weiter von Vorteil, dass insbesondere beim Anfahren des Taumelscheibengetriebes ein Schlupf zwischen den beteiligten Getriebegliedern auftreten kann. Durch diesen minimalen Schlupf wird ein Nachfedern zwischen den Getriebegliedern ermöglicht, das sich positiv auf die Arbeitsweise und Lebensdauer des Taumelscheibengetriebes auswirkt. Durch dieses Nachfedern werden das Anfahren und auftretende Stoßlasten besser bewältigt, da nicht zu stark beschleunigt wird. Außerdem ist die erfindungsgemäße Lösung aufgrund ihrer Einfachheit auch sehr kostengünstig herzustellen.The decisive advantage of this inventive reduction of a swash-plate mechanism is that it can be saved by the direct investment of wobble body and drive element radial and axial space. Thus, the required according to the prior art, timing belt and pulleys are no longer required. Another advantage is that by the immediate investment of wobble body and drive element occurring vibrations effect can be fully steamed. It is also advantageous that, in particular when starting the swashplate gear slip between the gear members involved can occur. Due to this minimal slip a Nachfedern between the gear members is made possible, which has a positive effect on the operation and life of the swashplate gear. By this Nachfedern the start and occurring shock loads are better handled, because not too much accelerated. In addition, the solution according to the invention is also very inexpensive to manufacture due to its simplicity.
Weitere vorteilhafte Ausführungsvarianten der Erfindung sind in den Unteransprüchen 2 bis 10 beschrieben.Further advantageous embodiments of the Invention are in the subclaims 2 to 10 described.
Nach einem weiteren Merkmal der Erfindung gemäß Anspruch 2 soll das Antriebselement an dem Teilbereich der Mantelfläche mit der größten radialen Ausdehnung anliegen. Durch die dabei sich einstellenden Größenverhältnisse ist eine maximale Untersetzung realisiert.To a further feature of the invention according to claim 2, the drive element at the partial area of the lateral surface with the largest radial extent issue. By thereby adjusting proportions is a maximum reduction realized.
Nach Anspruch 3 ist vorgesehen, dass das Antriebselement eine Welle eines Elektromotors ist, auf die ein elastischer Ring aufgeschoben ist, der kraftschlüssig an der äußeren Mantelfläche des Taumelkörpers anliegt, wobei in vorteilhafter Weise nach Anspruch 4 die Welle mit einer umlaufenden Nut versehen sein soll, in die der elastische Ring eingesetzt ist. Nach einem weiteren Merkmal der Erfindung gemäß Anspruch 5 soll dieser elastische Ring als ein O-Ring ausgebildet sein. Aus Anspruch 6 geht hervor, dass der elastische Ring mit einer Profilierung vorgesehen ist, die in eine korrespondierende Verzahnung des Taumelkörpers eingreift.To Claim 3 is provided, that the drive element is a shaft of a Electric motor is pushed onto which an elastic ring, the non-positive on the outer surface of the tumbling body is applied, wherein in an advantageous manner according to claim 4, the shaft should be provided with a circumferential groove in which the elastic Ring is inserted. According to a further feature of the invention according to claim 5, this elastic ring should be formed as an O-ring. Out Claim 6 shows that the elastic ring provided with a profiling is, which engages in a corresponding toothing of the wobble body.
Eine andere Untersetzungsvariante für ein Taumelscheibengetriebe ist in Anspruch 7 beschrieben. Danach ist vorgesehen, dass das Antriebselement eine Welle eines Elektromotors ist, auf der ein Wälzlager angeordnet ist, dessen in axialer Richtung verlängerter Käfig mit dem Taumelkörper in Wirkverbindung steht. Dabei ergeben sich zwei Möglichkeiten, die in den Ansprüchen 8 und 9 beschrieben sind.A other reduction variant for a swash plate transmission is described in claim 7. After that it is provided that the drive element is a shaft of an electric motor is on a rolling bearing is arranged, whose elongated cage in the axial direction with the swash body in Active compound is. This results in two ways that in the claims 8 and 9 are described.
Nach Anspruch 8 ist vorgesehen, dass das Wälzlager ein Zylinderrollenlager ist und der Käfig eine erste Außenverzahnung aufweist, die formschlüssig in eine zweite Außenverzahnung des Taumelkörpers eingreift. Die kraftschlüssige Variante geht aus Anspruch 9 hervor. Danach soll das Wälzlager ein Zylinderrollenlager sein und der Käfig kraftschlüssig an der äußeren Mantelfläche des Taumelkörpers anliege. Schließlich ist nach einem letzten Merkmal der Erfindung gemäß Anspruch 10 vorgesehen, dass das Wälzlager vorgespannt ist. Ein vorgespanntes Wälzlager sorgt dafür, dass die zwischen Welle und Außenring angeordneten Wälzkörper möglichst schlupffrei abrollen und die Antriebsmomente damit wirkungsvoll übertragen werden.To Claim 8 is provided that the rolling bearing is a cylindrical roller bearing and the cage is one first external toothing having the form-fitting in a second external toothing of the body intervenes. The non-positive Variant is apparent from claim 9. Thereafter, the rolling bearing be a cylindrical roller bearing and the cage non-positively the outer surface of the tumbling body anliege. After all is provided according to a last feature of the invention according to claim 10 that the rolling bearing is biased. A preloaded roller bearing ensures that the between shaft and outer ring arranged rolling elements as possible Unroll without slippage and effectively transfer the drive torques become.
Die Ertindung wird an nachstehenden Ausführungsbeispielen näher erläutert.The Ertindung will be explained in more detail in the following embodiments.
