Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Taumelscheibengetriebe, welches einen Taumelkörper sowie zwei Wälzlager aufweist, wobei jeweils ein Lagerinnenring eines Wälzlagers an dem Taumelkörper befestigt ist, während die zugehörigen Lageraußenringe der Wälzlager als Taumelscheibe beziehungsweise als Gehäusescheibe des Taumelscheibengetriebes fungieren.The The invention relates to a swash plate mechanism which has a tumbling body and two rolling bearings, each having a bearing inner ring a rolling bearing attached to the wobble body is while the associated bearing outer rings the rolling bearing as a swash plate or as a housing plate of the swash plate mechanism.

Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein für eine Axialkolbenpumpe geeignetes Taumelscheibengetriebe gegenüber dem Stand der Technik derart weiterzuentwickeln, dass es auf besonders einfache Weise in eine Umgebungskonstruktion integrierbar ist.Of the Invention is based on the object, one for an axial piston pump suitable swash plate gear with respect to the state of To develop technology such that it is particularly simple Way can be integrated into a surrounding construction.
Zusammenfassung der ErfindungSummary of the invention
Diese
Aufgabe wird erfindungsgemäß gelöst durch
ein Taumelscheibengetriebe mit den Merkmalen des Anspruchs 1. Dieses
Taumelscheibengetriebe weist einen zwischen einer Taumelscheibe
und einer Gehäusescheibe drehbar gelagerten Taumelkörper
auf, wobei die Taumelscheibe einen Lageraußenring eines
ersten Wälzlagers und die Gehäusescheibe einen
Lageraußenring eines zweiten Wälzlagers bildet,
welches vorzugsweise identische Abmessungen wie das erste Wälzlager
aufweist. Die Lagerinnenringe der beiden Wälzlager sind
an dem Taumelkörper befestigt, wobei zwischen dem Lageraußenring
und dem Lagerinnenring jeweils eine Dichtung angeordnet ist. Da
jedes Wälzlager des Taumelscheibengetriebes separat gegen
Schmiermittelaustritt abgedichtet ist, ist es nicht erforderlich,
den Bauraum, in welchem sich das Taumelscheibengetriebe befindet, insgesamt
gegen Schmiermittelaustritt abzudichten, wie dies beispielsweise
beim Taumelscheibengetriebe nach der
Die Dichtungen, welche vorzugsweise als berührende Dichtungen ausgebildet sind, sind bevorzugt am Lageraußenring, das heißt an der Gehäusescheibe beziehungsweise an der Taumelscheibe, befestigt. Der Lagerinnenring weist hierbei in bevorzugter Ausgestaltung einen Bord auf, der radial außerhalb des Lageraußenrings angeordnet ist.The Seals, which preferably as contacting seals are formed, are preferably on the bearing outer ring, the means on the housing plate or on the swash plate, attached. The bearing inner ring points in this case preferred embodiment of a board on the radially outside the bearing outer ring is arranged.
Für die Schmierung der Wälzlager sind grundsätzlich beliebige herkömmliche Schmierstoffe geeignet. Insbesondere kommen auch Festschmierstoffe, beispielsweise Graphit oder Molybdändisulfid, zur Schmierung der abgedichteten Wälzlager des Taumelscheibengetriebes in Betracht.For the lubrication of the bearings are basically any conventional lubricants suitable. Especially also come solid lubricants, such as graphite or molybdenum disulfide, to Lubrication of the sealed bearings of the swash plate mechanism into consideration.
Nach einer bevorzugten Weiterbildung ist die Dichtung als stahlarmiere Elastomerdichtung ausgebildet. Hierbei kann eine Stahlarmierung unmittelbar über einen Lagerring gebördelt sein.To In a preferred development, the seal is as a steel arm Elastomeric seal formed. This can be a steel reinforcement be crimped directly over a bearing ring.
Der Lageraußenring eines jeden Wälzlagers weist in bevorzugter Ausgestaltung einen zur Symmetrieachse des jeweiligen Lagers normalen ringscheibenförmigen Abschnitt sowie eine radial außen hieran anschließenden, im Querschnitt gekrümmten Abschnitt auf. Der letztgenannte Abschnitt ist hierbei im Querschnitt der Form der Wälzkörper, vorzugsweise Kugeln, angepasst und dem Innenring des jeweiligen Wälzlagers, das heißt dem Taumelkörper, zugewandt. Der mit dem Innendurchmesser des gekrümmten Abschnitts identische Außendurchmesser des ringscheibenförmigen Abschnitts ist vorzugsweise kleiner als der Teilkreisdurchmesser des Wälzlagers, das heißt der Durchmesser des Kreises, welcher durch die Mittelpunkte der einzelnen Wälzkörper beschrieben ist.Of the Bearing outer ring of each bearing points in preferred embodiment one to the axis of symmetry of the respective Bearing normal ring-shaped section as well as a radially adjoining thereto, in cross section curved section on. The latter section is here in cross-section the shape of the rolling elements, preferably balls, adapted and the inner ring of the respective Rolling bearing, that is the tumbling body, facing. The one with the inner diameter of the curved Section identical outer diameter of the annular disc-shaped Section is preferably smaller than the pitch circle diameter of the rolling bearing, that is the diameter of the Circle, which is described by the centers of the individual rolling elements is.
