Die Erfindung bezieht sich auf eine Andrückscheibenanordnung bei einer Schiefscheiben-Axialkolbenmaschine (Pumpe oder Motor), deren Zylindertrommel aus zwei Teilen mit Bohrungen besteht, die für jeden der durch die Andrückscheibe federnd auf die Schiefscheibe gedrückten Kolben zwei voneinander entfernt liegende Lagerstellen bilden.The invention relates to a pressure plate arrangement in a swash plate axial piston machine (pump or motor), the cylinder drum of which consists of two parts with bores which for each of the pistons that are resiliently pressed onto the swash plate by the pressure plate, two bearing points are formed at a distance from one another.
Bei einer bekannten Axialkolbenmaschine dieser Art ist die Andrückscheibe zwischen der triebseitigen Lagerstelle der Kolben und den Kolbenschuhen angeordnet. Dadurch kann die Andrückscheibe Kippmomente auf die Kolben ausüben, so daß die Kolben nicht querkraftsfrei in den beiden Lagerstellen der Zylindertrommel geführt sind. Dieser Nachteil der nicht querkraftsfreien Kolbenführung ist insbesondere bei hohen Drehzahlen und hohen Drücken von Bedeutung.In a known axial piston machine of this type, the pressure disk is between the drive-side Arranged bearing point of the piston and the piston shoes. As a result, the pressure disc can exert tilting moments on the pistons, so that the pistons are not guided free of transverse forces in the two bearing points of the cylinder drum. This disadvantage of Piston guidance that is not free of transverse forces is particularly important at high speeds and high pressures.
Der Erfindung liegt die Aufgabe zugrunde, die Kolben möglichst querkraftsfrei in den beiden Teilen der Zylindertrommel zu führen. Dies wird nach der Erfindung dadurch erreicht, daß die Andrückscheibe zwischen den beiden Lagerstellen angeordnet ist. Durch diese Anordnung der Andrückscheibe wird eine Ausübung eines Kippmoments auf die Kolben verhindert, so daß eine praktisch querkraftsfreie as Kolbenführung erzielt wird. Außerdem kann die Schiefscheibe näher an die Zylindertrommel herangerückt werden, wodurch die Baulange der Maschine verringert wird.The invention is based on the object of providing the pistons with as little transverse force as possible in the two parts to guide the cylinder drum. This is achieved according to the invention in that the pressure disc is arranged between the two bearings. This arrangement of the pressure disc is prevents a tilting moment from being exerted on the pistons, so that a practically transverse force-free as Piston guide is achieved. In addition, the swash plate can be moved closer to the cylinder drum, reducing the overall length of the machine is decreased.
Zu der möglichst querkraftsfreien Kolbenführung trägt es in weiterer Ausbildung der Erfindung bei, wenn die Andrückscheibe kappenförmig ausgebildet und auf einem Kugelkopf gelagert ist, der sich unter Zwischenschaltung einer Feder in der Zylindertrommel abstützt.In a further development of the invention, it contributes to piston guidance that is as free from lateral forces as possible, when the pressure washer is cap-shaped and mounted on a ball head that is located below Interposition of a spring in the cylinder drum is supported.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Dabei handelt es sich um eine Schiefscheiben-Axialkolbenpumpe, die in der Zeichnung im Längsschnitt dargestellt ist, wobei einige Teile der Pumpe zur besseren Anschaulichkeit nicht geschnitten dargestellt sind.An exemplary embodiment of the invention is shown in the drawing. This is a Swash plate axial piston pump, which is shown in the drawing in longitudinal section, with some Parts of the pump are not shown in section for the sake of clarity.
Die dargestellte Schiefscheiben- Axialkolbenpumpe besteht aus einem Gehäuse 1 mit einem Tragezapfen 2 und einem Deckel 3, der die Schiefscheibe 4 bildet. Die auf dem Wälzlager 5 und in dem Wälzlager 6 laufende Zylindertrommel wird durch eine kerbverzahnte Triebwelle 7 mit Dichtungen 8 und 9 angetrieben. Die Zylindertrommel enthält eine Anzahl, z.B. sieben Zylinder 12 mit Kolben 13. Die Zylinder 12 haben Öffnungen 14, die mit einer auf so einer kugeligen Auflagefläche 18 durch Lagerung auf drei Kugeln 19 verstellbaren Steuerspiegelscheibe 17The swash plate axial piston pump shown consists of a housing 1 with a support pin 2 and a cover 3 which forms the swash plate 4. The cylinder drum running on the roller bearing 5 and in the roller bearing 6 is driven by a splined drive shaft 7 with seals 8 and 9 driven. The cylinder barrel contains a number, e.g. seven cylinders 12 with pistons 13. The Cylinders 12 have openings 14 which are connected to such a spherical bearing surface 18 by storage three balls 19 adjustable control mirror disk 17 Andrückscheibenanordnung bei einer Schiefscheiben-AxialkolbenmaschinePressure washer arrangement at a Swash plate axial piston machine

den Einlaß- und den Förderkanal bilden. Die Zylindertrommel 15 besteht aus zwei Teilen 21 und 22, die durch z.B. drei Zapfen23 aufeinandergesetzt und durch z.B. drei Schrauben24 verbunden sind. Der Teil 21 hat Bohrungen 25, die die Zylinder 12 und die eine Lagerstelle für die Kolben 13 bilden. Der Teil 22 weist ebenfalls Bohrungen 26 auf, die die zweite Lagerstelle der Kolben 13 bilden.form the inlet and the delivery channel. The cylinder drum 15 consists of two parts 21 and 22, which are placed on top of each other by e.g. three pegs23 and connected by e.g. three screws24. Of the Part 21 has bores 25 which form the cylinders 12 and which form a bearing point for the pistons 13. Part 22 likewise has bores 26 which form the second bearing point of the pistons 13.
Die Andrückscheibe 27 der Maschine ist zwischen den beiden Lagerstellen 25 und 26 für die Kolben 13 innerhalb der Zylindertrommel 15 angeordnet. Sie ist kappenförmig ausgebildet und auf dem Kugelkopf 28 gelagert, der seinerseits unter Zwischenschaltung einer Feder 29 in dem Teil 21 der Zylindertrommel geführt ist. Die Feder 29 stützt sich einerseits auf der ZylindertrommellS ab und drückt andererseits die Andrückscheibe 27 und damit über die Ringe 30 die Kolben 13 und die Kolbenschuhe 31 mit Kugelkopf 32 auf die Schiefscheibe 4. Die Kolben 13 werden durch die mit der Triebwelle 7 verbundene Zylindertrommel angetrieben.The pressure disk 27 of the machine is between the two bearing points 25 and 26 for the pistons 13 arranged within the cylinder drum 15. It is designed in the shape of a cap and on the ball head 28 stored, which in turn with the interposition of a spring 29 in the part 21 of the cylinder drum is led. The spring 29 is supported on the one hand on the cylinder drum S and on the other hand presses the Pressure disk 27 and thus the piston 13 and the piston shoes 31 with a spherical head via the rings 30 32 onto the swash plate 4. The pistons 13 are driven by the cylinder drum connected to the drive shaft 7.
Wie die Zeichnung zeigt, insbesondere in ihrem unteren Teil, der der oberen Totpunktstellung entspricht, kann die Schiefscheibe 4 sehr nahe an die Zylindertrommel 15 herangerückt werden, was zu einer geringen Baulänge der Maschine führt. Die durch die Anordnung der Andrückscheibe 27 zwischen den beiden Lagerstellen 25 und 26 erzeugte querkraftsfreie Kolbenführung ermöglicht eine sehr starke Neigung der Schiefscheibe 4, so daß die Maschine mit besonders hohen Drücken arbeiten kann.As the drawing shows, especially in its lower part, which corresponds to the top dead center position, the swash plate 4 can be very close to the Cylinder drum 15 are moved closer, which leads to a short overall length of the machine. the generated by the arrangement of the pressure disc 27 between the two bearing points 25 and 26 Piston guide free of transverse forces enables the swash plate 4 to incline very sharply, so that the machine can work with particularly high pressures.
