Abstract

The radial piston machine has a cylinder body (6) which rotates on a control pin (5) which is fixed to the housing. A plurality of radially running holes (7) are constructed in the cylinder body, in which pistons (8) slide which are supported via sliding shoes (9) on the guide surface of a lifting ring (11). The sliding shoes are held in continuous contact with the guide surface by means of retaining rings (12, 13). On the outer circumference of the retaining rings there are constructed passages (22) through which the region on the sole of the sliding shoes is connected to the interior of the machine, e.g. via longitudinal slots (25, 26) which are located in the side surfaces facing the cylinder body. The retaining rings consist of a filled plastic, e.g. glass fibre or carbon fibre reinforced, which has high strength and a low thermal coefficient of expansion. The passages on the outer circumference are constructed such that they provide good movement characteristics with respect to the movement partner and cause no wear. <IMAGE>

Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Radialkolbenmaschine nach der Gattung des Hauptanspruchs. Bei derartigen bekannten Radialkolben­maschinen bestehen die Halteringe aus einem metallischen Werkstoff bzw. aus einem üblichen Kunststoff. Um die Ölzirkulation innerhalb des Pumpengehäuses zu verbessern, weisen die Halteringe Aussparungen am Umfang auf. Bei ungunstiger Auslegung derselben können deren Be­grenzungen wie Schneiden an einem Werkzeug wirken und zu Verschleiß am Gegenlaufpartner führen. Werden die abgetragenen Materialteilchen in den Haltering abgelagert, ist der Verschleiß ständig fortschrei­tend.The invention is based on a radial piston machine according to the preamble of the main claim. In such known radial piston machines, the retaining rings are made of a metallic material or a common plastic. In order to improve the oil circulation within the pump housing, the retaining rings have cutouts on the circumference. If the design is unfavorable, their limitations can act like cutting on a tool and lead to wear on the counterpart. If the removed material particles are deposited in the retaining ring, the wear is progressively increasing.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Radialkolbenmaschine mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß sie eine höhere Lebensdauer aufweist, und zwar dadurch, daß die Halte­ringe und die mit diesen in Berührung stehenden Gehäuseflächen prak­tisch keinem Verschleiß unterworfen sind. Dies wird dadurch er­reicht, daß die Halteringe gute Laufeigenschaften aufweisen und die Aussparungen am Außenumfang verschleißmindernd gestaltet sind.The radial piston machine according to the invention with the characterizing features of the main claim has the advantage that it has a longer service life, namely in that the retaining rings and the housing surfaces in contact with them are subject to virtually no wear. This is achieved in that the retaining rings have good running properties and the cutouts on the outer circumference are designed to reduce wear.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vor­teilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Merkmale möglich.Advantageous further developments and improvements of the features specified in the main claim are possible through the measures listed in the subclaims.

Zeichnungdrawing

Ein Ausführungsbeispiel der Erfindung ist in der nachfolgenden Zeichnung dargestellt und in der Beschreibung näher erläutert. Es zeigen Figur 1 einen Längsschnitt durch eine Radialkolbenmaschine, Figur 2 einen Haltering in Ansicht, Figur 3 einen Querschnitt des Halterings.An embodiment of the invention is shown in the following drawing and explained in more detail in the description. FIG. 1 shows a longitudinal section through a radial piston machine, FIG. 2 shows a retaining ring in view, FIG. 3 shows a cross section of the retaining ring.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Die Radialkolbenpumpe hat ein etwa topfförmiges Gehäuse 1, das von einem Gehäusedeckel 2 verschlossen ist. Von der dem Gehäusedeckel 2 abgewandten Stirnseite des Gehäuses geht eine Bohrung 3 aus, die in eine Ausnehmung 4 mündet, die einen Abschnitt des Gehäuseinneren bildet. In die Bohrung 3 ist ein Steuerzapfen 5 eingepreßt, der mit einem Längenabschnitt in die Ausnehmung 4 ragt. In der Ausnehmung 4 ist ein Zylinderkörper 6 angeordnet, der mit einer Bohrung 6ʹ auf dem Steuerzapfen drehbar gelagert ist und in radial verlaufenden Bohrungen 7 Kolben 8 aufnimmt, welche sich mit Gleitschuhen 9 auf einer Führungsfläche 10 eines Hubrings 11 abstützen. Ist die Maschine verstellbar ausgebildet, dann ist der Hubring 11 in der Ausnehmung 4 zur Änderung des Kolbenhubes verschiebbar angeordnet, was aber im Zusammenhang mit der Erfindung nicht gezeigt ist. Beid­seits des Gleitschuh-Fußes befinden sich Halteringe 12, 13, die die Aufgabe haben, den Gleitschuh stets an der Fuhrungsfläche 10 des Hubrings in Kontakt zu halten. Zu diesem Zweck greift eine vor­stehende Ringkante 12ʹ, 13ʹ des Halterings etwas über den Fuß des Gleitschuhs.The radial piston pump has an approximately cup-shaped housing 1, which is closed by a housing cover 2. A bore 3 extends from the end face of the housing facing away from the housing cover 2 and opens into a recess 4, which forms a section of the interior of the housing. In the bore 3, a control pin 5 is pressed, which projects into the recess 4 with a longitudinal section. In the recess 4, a cylinder body 6 is arranged, which is rotatably mounted with a bore 6ʹ on the control pin and receives pistons 8 in radially extending bores 7, which are supported with sliding shoes 9 on a guide surface 10 of a cam ring 11. If the machine is designed to be adjustable, then the cam ring 11 is displaceably arranged in the recess 4 for changing the piston stroke, but this is not shown in connection with the invention. On both sides of the slide shoe foot there are retaining rings 12, 13, which have the task of always keeping the slide shoe in contact on the guide surface 10 of the lifting ring. For this purpose, a projecting ring edge 12ʹ, 13ʹ of the retaining ring engages somewhat over the foot of the sliding block.

Die Halteringe 12, 13 bestehen aus einem gefüllten Kunststoff - ­z. B. glasfaserverstärktem oder kohlefaserverstärktem Kunststoff. Sie weisen neben höherer Festigkeit auch einen geringeren Wärmedeh­nungskoeffizienten auf, was sehr wichtig ist in Verbindung mit Metallbauteilen wegen der annähernd gleichen Wärmedehnung. Dadurch wird ein Klemmen von Gleitschuhen durch die Halteringe verhindert.The retaining rings 12, 13 consist of a filled plastic - for. B. glass fiber reinforced or carbon fiber reinforced plastic. In addition to higher strength, they also have a lower coefficient of thermal expansion, which is very important in connection with metal components because of the approximately the same thermal expansion. This prevents sliding shoes from jamming through the retaining rings.

Für wasserhaltige Hydraulikflüssigkeiten eignet sich ein Werkstoff mit geringem Wasseraufnahmevermögen, z. B. ein gefüllter Polyoxy­methylen-Kunststoff.A material with low water absorption capacity, e.g. B. a filled polyoxymethylene plastic.

Am Außenumfang der Halteringe sind eine oder mehrere Nuten 22 ausge­bildet, über welche Schmutzteilchen abgeführt werden.On the outer circumference of the retaining rings, one or more grooves 22 are formed, via which dirt particles are removed.

An der dem Zylinderkörper und dem Haltering 12 zugewandten Seite des Gehäuses sind mehrere schmale Längsnuten 25 ausgebildet, die sich bis zum Steuerzapfen 5 und damit in das Gehäuseinnere erstrecken. Auch am Deckel 2 sind auf der dem Zylinderkörper bzw. Haltering 13 zugewandten Innenseite des Deckels mehrere, nunmehr aber wesentlich kürzere Längsnuten 26 ausgebildet, die ebenfalls ins Innere des Gehäuses führen. Damit besteht eine Druckmittelverbindung vom Gleit­schuh über die Halteringe zum Gehäuseinneren, so daß Schmutz­teilchen, die sich im Bereich der Gleitschuhe befinden, in das Ge­häuseinnere gespült werden. Von dort gelangen sie in den Behälter und bleiben im Filter hängen. Damit wird erreicht, daß Schmutz­teilchen kaum an die Gleitschuhsohle gelangen, so daß Fresser am Gleitschuh unterbleiben und auch mit dieser Maßnahme die Lebensdauer der Maschine zum Teil wesentlich verbessert werden kann.On the side of the housing facing the cylinder body and the retaining ring 12, a plurality of narrow longitudinal grooves 25 are formed, which extend as far as the control pin 5 and thus into the interior of the housing. Also on the cover 2, on the inside of the cover facing the cylinder body or retaining ring 13, several, but now considerably shorter, longitudinal grooves 26 are formed, which likewise lead into the interior of the housing. There is thus a pressure medium connection from the slide shoe via the retaining rings to the interior of the housing, so that dirt particles which are located in the area of the slide shoes are flushed into the interior of the housing. From there they get into the container and get caught in the filter. This ensures that dirt particles hardly get to the sole of the shoe, so that there is no seizure on the shoe and this measure can also significantly improve the service life of the machine.

Am Steuerzapfen 5 sind zwei einander diametral gegenuberliegende Steueröffnungen 14, 15 ausgebildet, die mit den Mündungen der Zylin­derbohrungen 7 zusammenwirken und in die je ein teilweise im Gehäuse 1, teilweise im Steuerzapfen verlaufender Kanal 16, 17 für den Zu- oder Abfluß von Druckmittel mündet. Die beiden Steueröffnungen 14, 15 sind durch Querstege 18, 19 voneinander getrennt. Im Steuer­zapfen 5 ist eine Ringnut 20 ausgebildet, die, wenn dieser in die Bohrung 3 eingepreßt ist, sich dort befindet, wo die Bohrung 3 in die Ausnehmung 4 übergeht; dort mündet auch die Längsnut 25.On the control pin 5 two diametrically opposed control openings 14, 15 are formed, which cooperate with the mouths of the cylinder bores 7 and in each of which is partially in the housing 1, partially in the control pin channel 16, 17 opens for the inflow or outflow of pressure medium. The two control openings 14, 15 are separated from one another by transverse webs 18, 19. In the control pin 5, an annular groove 20 is formed, which, when this is pressed into the bore 3, is located where the bore 3 merges into the recess 4; the longitudinal groove 25 also opens there.
