Description

Hydrostatische Axialkolbenmaschine Hydrostatic axial piston machine

Die Erfindung betrifft eine verstellbare hydrostatische Axialkolbenmaschine mit einem trommeiförmigen Zylinderblock, der auf einer Antriebs- oder Abtriebswelle, deren eines Ende in einer Bohrung des Bodens eines topfförmigen Gehäuses gelagert ist, drehfest gehaltert und konzentrisch und parallel zu dessen Mittellinie mit Zylinderbohrungen versehen ist, in denen axial verschiebliche Kolben angeordnet sind, die sich über kugelförmige Köpfe auf eine Schrägscheibe oder eine schräge Seite eines durch Wälzlager auf Wellenzapfen schwenkbar in dem Gehäuse gelagerten und mit einem Schwenkantrieb versehenen wiegenförmigen Körpers abstützen.The invention relates to an adjustable hydrostatic axial piston machine with a drum-shaped cylinder block which is rotatably supported on a drive or output shaft, one end of which is mounted in a bore in the bottom of a pot-shaped housing, and is provided concentrically and parallel to the center line thereof with cylinder bores in which axially displaceable pistons are arranged which are supported via spherical heads on a swash plate or an inclined side of a cradle-shaped body which is pivotably mounted in the housing by roller bearings on shaft journals and is provided with a pivot drive.

Es ist bekannt, den wiegenförmigen Körper einer verstellbaren hydrostatischen Axialkolbenmaschine mit einer halbzylindrischen Stützfläche zu versehen und diese über in einem Käfig gelagerte Wälzkörper, beispielsweise zylindrische Walzen, auf einer konzentrischen zylindrischen Schale des Gehäuses abzustützen. Bei einer derartigen Lagerung müssen jedoch besondere Maßnahmen getroffen werden, um zu verhindern, daß der Käfig mit den Wälzkörpern auswandert. Weiterhin sind verstellbare hydrostatische Axialkolbenmaschinen der eingangs angegebenen Art bekannt, bei denen die Wellenzapfen der wiegenförmigen Körper über Wälzlager in Bohrungen des Gehäuses gelagert sind, die durch übliche Lagerdeckel verschlossen sind.It is known to provide the cradle-shaped body of an adjustable hydrostatic axial piston machine with a semi-cylindrical support surface and to support this on a concentric cylindrical shell of the housing via rolling elements mounted in a cage, for example cylindrical rollers. With such a storage, however, special measures must be taken to prevent the cage from migrating with the rolling elements. Furthermore, adjustable hydrostatic axial piston machines of the type specified at the outset are known, in which the shaft journals of the cradle-shaped bodies are supported by roller bearings in bores in the housing which are closed by conventional bearing covers.

Aufgabe der Erfindung ist es, eine verstellbare hydrostatische Axialkolbenmaschine der eingangs angegebenen Art zu schaffen, die mit einer einfachen und in dem Gehäuse gekapselten Lagerung für die Wellenzapfen des wiegenförmigen Körpers versehen ist.The object of the invention is to provide an adjustable hydrostatic axial piston machine of the type specified at the outset, which is provided with a simple and encapsulated bearing in the housing for the shaft journals of the cradle-shaped body.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Gehäuse auf seiner Innenseite beidseits der Antriebs- oder Abtriebswelle mit etwa halbzylindrischen Schalen versehen ist, in die die Wälzlager eingesetzt und in denen sie durch bügeiförmige Halteteile gehalten sind.According to the invention this object is achieved in that the housing is provided on its inside on both sides of the drive or output shaft with approximately semi-cylindrical shells into which the rolling bearings are inserted and in which they are held by bow-shaped holding parts.

Bei der erfindungsgemäßen Lagerung befinden sich die vorzugsweise einstückig mit dem Gehäuse ausgebildeten halbzylindrischen Schalen auf der der Schrägfläche des wiegenförmigen Körpers gegenüberliegenden Seite, so daß sie in Richtung der auf den wiegenförmigen Körper ausgeübten wesentlichen Kräfte liegen und die bügeiförmigen Halteteile überhaupt nicht oder nur schwach belastet sind.In the storage according to the invention, the semi-cylindrical shells, which are preferably formed in one piece with the housing, are located on the side opposite the inclined surface of the cradle-shaped body, so that they lie in the direction of the essential forces exerted on the cradle-shaped body and the bow-shaped holding parts are not or only slightly loaded ,

Das topfförmige Gehäuse der verstellbaren hydrostatischen Axialkolbenmaschine braucht zur Anordnung und Montage der Lagerung des wiegenförmigen Körpers nicht mit zusätzlichen Öffnungen versehen zu sein, was eine kompakte Konstruktion ermöglicht und eine zusätzliche Geräuschdämmung zur Folge hat.The pot-shaped housing of the adjustable hydrostatic axial piston machine does not have to be provided with additional openings for the arrangement and assembly of the bearing of the cradle-shaped body, which enables a compact construction and results in additional noise insulation.

Zweckmäßigerweise sind die Schalen parallel zu der die Antriebs- oder Abtriebswelle rechtwinkelig schneidenden Mittelebene der Wellenzapfen mit Rändern versehen, die Auflagen zur Befestigung von von den Bügeln abgebogenen Halteteilen bilden. Die Halteteile können mit Befestigungsbohrungen für in die Ränder einschraubbare Befestigungsschrauben versehen sein.The shells are expediently provided with edges parallel to the central plane of the shaft journal which intersects the drive or output shaft at right angles, which form supports for fastening holding parts bent from the brackets. The holding parts can be provided with fastening holes for fastening screws that can be screwed into the edges.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigtAn embodiment of the invention is explained below with reference to the drawing. In this shows

Fig. 1 einen Axialschnitt durch eine verstellbare hydrostatische Axialkolbenpumpe mit zwei auf miteinander gekuppelten Wellen angeordneten Zylinderblöcken undFig. 1 shows an axial section through an adjustable hydrostatic axial piston pump with two cylinder blocks arranged on mutually coupled shafts and

Fig. 2 einen Schnitt durch die Axialkolbenmaschine längs der Linie A-A in Fig. 1.FIG. 2 shows a section through the axial piston machine along the line A-A in FIG. 1.

Aus Fig. 1 ist ein Längsschnitt durch eine verstellbare hydrostatische Doppelaxialkolbenmaschine ersichtlich, bei der auf einer gekuppelten Welle, die aus den Wellenabschnitten 1 besteht, über Vielkeilverzahnungen 2 zwei trommeiförmige Zylinderblöcke 3 gehaltert sind. Die beiden auf der Welle 1 angeordneten Zylinderblöcke 3 mit zugehörigen topfförmigen Gehäusen 4 Ölzu- und -abführungen sowie Steuerbzw. Verteilerplatten sind grundsätzlich spiegelbildlich zu der radialen Mittelebene bis auf den Unterschied aufgebaut, daß die Welle 1 mit Ihrem Wellenzapfen 5 aus dem Gehäuse 4 herausgeführt ist, so daß die Erfindung nur an dem linken Teil der Doppelaxialkolbenpumpe beschrieben wird, weil die erfinderische Lagerung des wiegenförmigen Körpers selbstverständlich auch bei einer einfachen hydrostatischen Axialkolbenmaschine verwirklicht werden kann, bei der das dem Antriebsoder Abtriebswellenzapfen 5 gegenüberliegende Ende der Welle 1 in einem das topfförmige Gehäuse abschließenden Deckel gelagert ist.1 shows a longitudinal section through an adjustable hydrostatic double-axial piston machine, in which two drum-shaped cylinder blocks 3 are held on a coupled shaft, which consists of the shaft sections 1, by means of splines 2. The two arranged on the shaft 1 cylinder blocks 3 with associated cup-shaped housings 4 oil supply and discharge as well as Steuerbzw. Distribution plates are basically a mirror image of the radial central plane except for the difference that the shaft 1 with its shaft journal 5 is led out of the housing 4, so that the invention is only described on the left part of the double axial piston pump, because the inventive bearing of the cradle-shaped body can of course also be implemented in a simple hydrostatic axial piston machine in which the end of the shaft 1 opposite the drive or driven shaft journal 5 is mounted in a cover which closes the cup-shaped housing.

Das topfförmige Gehäuse 4 weist einen Boden 6 mit einer abgestuften Bohrung auf, in der die Welle 1 durch ein Wälzlager 7 gelagert ist, das durch einen Lagerdeckel 8 in üblicher Weise gehaltert ist. Das topfförmige Gehäuse 4 ist, wie am besten aus Fig. 2 ersichtlich ist, auf gegenüberliegenden Seiten einstückig mit Einziehungen 9 versehen, die halbzylindrische Schalen 10 aufweisen. An diese halbzylin- drische Schalen schließen sich gerade verlaufende Abschnitte 11 an, die gerade Wandabschnitte bilden, die etwa tangential zu den schalenförmigen Ausnehmungen verlaufen und über Abrundungen an die schalenförmigen Ausnehmungen anschließen und leicht nach außen abgeschrägt sein können. Die geraden Wandungsabschnitte enden an die Einziehungen begrenzenden Stufen 12, die in einer gemeinsamen radialen Gehäuseebene liegen, die die Welle 1 rechtwinkelig kreuzt.The pot-shaped housing 4 has a bottom 6 with a stepped bore, in which the shaft 1 is supported by a roller bearing 7, which is supported in the usual manner by a bearing cover 8. The pot-shaped housing 4, as can best be seen from FIG. 2, is provided in one piece on opposite sides with indentations 9 which have semi-cylindrical shells 10. To these half-cylinder Drical shells are followed by straight sections 11, which form straight wall sections, which run approximately tangentially to the bowl-shaped recesses and connect to the bowl-shaped recesses via rounded portions and can be slightly beveled outwards. The straight wall sections end at the steps 12 which delimit the recesses and which lie in a common radial housing plane which crosses the shaft 1 at right angles.

Der wiegenförmige Körper 14 ist an seinen beiden Endseiten mit etwa wangen- oder scheibenförmigen Wellenzapfen 15 versehen, auf die Wälzlager 16 aufgesetzt sind. Diese Wälzlager 16 sind in die etwa halbzylindrischen Ausnehmungen 10 der Einziehungen 9 eingesetzt und in diesen durch streifenförmige Metallbügel 17 gehaltert, deren von deren Zylinder schalenförmig gekrümmten Mittelteilen abgebogenen Schenkel 18 mit Befestigungsbohrungen versehen sind, die Halteschrauben 19 durchsetzen, die in Gewindebohrungen auf den Stufen 12 eingeschraubt sind. The cradle-shaped body 14 is provided on its two end sides with approximately cheek-shaped or disk-shaped shaft journals 15, on which roller bearings 16 are placed. These roller bearings 16 are inserted into the approximately semi-cylindrical recesses 10 of the recesses 9 and held in them by strip-shaped metal brackets 17, the legs 18 of which bent from their cylinder shell-shaped curved middle parts are provided with mounting holes which pass through the retaining screws 19 which pass through threaded holes on the steps 12 are screwed in.
