Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Taumelscheibengetriebe gegenüber dem Stand der Technik zu vereinfachen, ohne signifikante Leistungseinschränkungen in Kauf nehmen zu müssen.Of the Invention is based on the object, a swash plate gear across from to simplify the prior art, without significant performance limitations to have to accept.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Taumelscheibengetriebe mit den Merkmalen des Patentanspruchs 1. Dieses Taumelscheibengetriebe weist eine mit einer Umgebungskonstruktion, beispielsweise einem Maschinengehäuse, nicht rotierbar verbundene Gehäusescheibe, einen Taumelkörper sowie eine Taumelscheibe auf. Der Taumelkörper ist mittels zweier Lager rotierbar zwischen der Gehäusescheibe und der Taumelscheibe gelagert, wobei eines der Lager als Gleitlager und das andere der Lager als Wälzlager ausgebildet ist. Der Taumelkörper bildet somit zugleich ein Teil eines Gleitlagers und ein Teil eines Wälzlagers. Vorzugsweise ist als Lagerung zwischen dem Taumelkörper und der zur Zusammenwirkung mit mindestens einem Axialkolben vorgesehenen Taumelscheibe ein Wälzlager, insbesondere ein Axial-Kugellager, vorgesehen, während die Lagerung des Taumelkörpers auf der Gehäusescheibe als Gleitlagerung ausgebildet ist. Durch die Gleitlagerung ist nicht nur die Konstruktion des Taumelscheibengetriebes vereinfacht, sondern auch der axiale Bauraumbedarf verringert.These The object is achieved by a swash plate mechanism with the features of the claim 1. This swashplate transmission has one with a surrounding construction, For example, a machine housing, non-rotatably connected Housing washer, a tumbling body and a swash plate. The wobble body is by means of two bearings rotatable between the housing disc and the swash plate mounted, wherein one of the bearings as a plain bearing and the other of the bearings as rolling bearings is trained. The tumbling body thus forms at the same time a part of a sliding bearing and a part of a Bearing. Preferably, as storage between the tumbling body and intended for cooperation with at least one axial piston Swash plate a rolling bearing, in particular an axial ball bearing, provided while the storage of the wobble body on the housing disc is designed as a sliding bearing. Due to the sliding bearing is not only the construction of the swash plate mechanism simplified, but also reduces the axial space requirement.
Das Gleitlager ist vorzugsweise als selbstzentrierendes Axial-Gleitlager gestaltet. Der Effekt der Selbstzentrierung ist insbesondere durch die rillenförmige Gestalt einer Gleitfläche erreichbar. Die Rille verläuft im Wesentlichen in einer normal zur Rotationsachse des Taumelkörpers angeordneten Ebene. Vorzugsweise befindet sich die Rille in der der Gehäusescheibe zugewandten Oberfläche des Taumelkörpers. Ebenso könnte jedoch auch die Gehäusescheibe mit einer Rille versehen sein, während an der Oberfläche des Taumelkörpers eine damit korrespondierende erhabene Struktur gebildet ist. In allen Fällen befindet sich die rillenförmige Gleitfläche vorzugsweise radial außerhalb der Wälzkörper des Wälzlagers des Taumelscheibengetriebes. Zur Zentrierung des Taumelkörpers relativ zur Gehäusescheibe können zusätzlich oder alternativ zur Rillenstruktur der Gleitfläche Zentrierflächen, beispielsweise konische Flächen, Zentrierrillen oder ähnliches vorgesehen sein.The Sliding bearing is preferably as a self-centering axial plain bearing designed. The effect of self-centering is in particular through the groove-shaped Shape of a sliding surface reachable. The groove runs essentially arranged in a normal to the axis of rotation of the wobble body Level. Preferably, the groove is in the housing disc facing surface of the body. Likewise could but also the housing disc be provided with a groove while on the surface of the body a corresponding raised structure is formed therewith. In all cases is the groove-shaped sliding surface preferably radially outside the rolling elements of the rolling bearing of the swashplate gear. For centering the wobble body relative to the housing disc can additionally or alternatively to the groove structure of the sliding surface centering surfaces, for example conical surfaces, Centering grooves or the like provided be.
Die
ein Teil des Gleitlagers bildende Gehäusescheibe ist beispielsweise
aus einem Sintermaterial, insbesondere Sintermetall, oder aus Kunststoff gefertigt.
Zur Bildung der Gleitoberfläche
sind auch Kohlenstoff-Verbundwerkstoffe, wie prinzipiell aus der
Der Taumelkörper ist in besonders rationeller Weise als spanlos umgeformtes Blechteil herstellbar. In besonders bevorzugter Ausführungsform ist auf jeder Seite dieses Blechteils spanlos eine Rille in die Oberfläche eingeformt. Die der Taumelscheibe zugewandte Rille dient als Laufrille für die Wälzkörper des Wälzlagers, während die der Gehäusescheibe zugewandte Rille als Teil des Gleitlagers dessen Selbstzentrierung bewirkt.Of the oscillatory body is in a particularly rational way as a chipless formed sheet metal part produced. In a particularly preferred embodiment is on each side this sheet metal part without a groove formed in the surface. The swashplate facing groove serves as a raceway for the rolling elements of the rolling bearing, while the housing disc facing groove as part of the sliding bearing whose self-centering causes.
Nach einer vorteilhaften Weiterbildung ist der Taumelkörper verliersicher mit der Gehäusescheibe gekoppelt. Ebenso ist eine verliersichere Kopplung des Taumelkörpers mit der Taumelscheibe realisierbar, so dass das gesamte Taumelscheibengetriebe eine einfach handhabbare, in einem einzigen Arbeitsschritt montierbare Baueinheit darstellt. Die verliersichere, jedoch drehbare Kopplung von Taumelkörper und Gehäusescheibe bzw. von Taumelkörper und Taumelscheibe ist vorzugsweise durch Schnappverbindungen hergestellt. In besonders bevorzugter Ausgestaltung ist zumindest die Schnappverbindung zwischen dem Taumelkörper und der Gehäusescheibe einstückig mit einem der Teile Taumelkörper und Gehäusescheibe, vorzugsweise mit dem Taumelkörper, ausgebildet. Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert. Hierin zeigen:To an advantageous development of the tumbling body is captive coupled with the housing plate. Likewise, a captive coupling of the wobble body with the swash plate feasible, so that the entire swash plate gear a easy to handle, mountable in a single step Building unit represents. The captive, but rotatable coupling of tumbling bodies and housing washer or of tumbling body and swash plate is preferably made by snap connections. In a particularly preferred embodiment, at least the snap connection between the tumbling body and the housing disc one piece with one of the parts tumbling bodies and housing disc, preferably with the wobble body, educated. Hereinafter will be an embodiment of the invention explained in more detail with reference to a drawing. Here in demonstrate:
