Description

Aus Pumpe und Motor bestehendes Flüssigkeitsgetriebe. Die Erfindung betrifft eine Steuerung für Kolbenmaschinen, deren Kolben eine Hubbewegung parallel zur Drehachse ausführen und deren Zvlinder einen Kreis ucn die Drehachse beschreiben. Solche Kolbenmaschinen werden insbesondere als Pumpen für hydraulische Pressen oder als Pumpen ttnci Antriebsmaschinen bei Flüssigkeitsgetrieben benutzt. Ventile, wie sie im gewöhnlichen Pumpenbau angewandt werden, können für die Steuerung dieser Maschinen nicht benutzt werden; es kommen für diesen Zweck nur Steuerungen in Frage, bei denen infolge der Drehung der Zvlinder tun die Achse Öffnungen im Zylinder abwechselnd die Zierbindung des Hubraumes mit den Zu- und Abflußleitungen herstellen. Diese Öffnungen können radial oder achsial angeordnet sein. Bei radialer Anordnung liegen die Steueröffnungen auf einem Zylinder; die unvermeidliche geringe Abnutzung führt zu Undichtheiten, die durch Nachstellen irgendeines Bauteiles nicht beseitigt «-erden können. Auch die Anordnung dieser Steueröffnungen in einer Ebene senkrecht zur Drehachse ist bekannt. In diesem Falle läßt sich die Größe des Spaltes zwischen dem sich drehenden Zylinderblock und den feststehenden Zu- und Abflußleitungen einstellen.Fluid gear consisting of pump and motor. The invention relates to a control for piston machines, the pistons of which have a stroke movement in parallel to the axis of rotation and whose cylinder describes a circle ucn the axis of rotation. Such piston machines are used in particular as pumps for hydraulic presses or used as pumps ttnci drive machines in fluid gears. Valves like they are used in normal pump construction, can be used to control this Machines are not used; only controls can be used for this purpose in which, as a result of the rotation of the cylinder, the axis has openings in the cylinder Alternately create the decorative binding of the cubic capacity with the inflow and outflow lines. These openings can be arranged radially or axially. With radial arrangement are the control ports on a cylinder; the inevitable low wear and tear leads to leaks that cannot be eliminated by readjusting any component «-Be able to earth. The arrangement of these control openings in a plane is also perpendicular to the axis of rotation is known. In this case, the size of the gap between the rotating cylinder block and the fixed inlet and outlet pipes.

Die Erfindung bezweckt nun, diese Einstellung selbsttätig zu bewirken. Zu diesem Zweck sind die Steueröffnungen in einer besonderen Scheibe angebracht, die mit dein Zylinderblock umläuft, gegen den Zylinderblock aber um ein geringes Maß längsverschiebbar angeordnet ist. Durch geeignete Bemessung der Steueröffnungen in dieser Scheibe ist es möglich, die Steuerscheibe durch den Druck der Flüssigkeit in den Zylindern gegen den Steuerspiegel anzupressen. Die Abdichtung der Steuerscheibe gegen die Zylinder geschieht am besten durch Manschetten aus Metall, Leder o. dgl.The invention now aims to effect this setting automatically. For this purpose, the control openings are placed in a special disc, which rotates with your cylinder block, but against the cylinder block by a little Dimension is arranged to be longitudinally displaceable. By appropriately dimensioning the control openings In this disc it is possible to control the control disc by the pressure of the liquid to press in the cylinders against the control plate. The sealing of the control disk against the cylinder is best done with sleeves made of metal, leather or the like.

Die Erfindung kann besonders vorteilhaft bei doppelhubigen Kolbenmaschinen verwendet werden. Durch. die symmetrische doppelseitige Anordnung der Kolben heben sich im allgemeinen die achsialen Kolbenkräfte gegenseitig auf. hur beim Ztt- und Abschalten einzelner Zvlinder können Restkräfte auftreten, die durch ein kleines Längskugellager aufgenommen werden können. Es hat sich jedoch gezeigt, daß zweckmäßig zur Aufnahme dieser Kräfte besondere Laufflächen im Steuerspiegel vorgesehen werden; ,.s ist dann jedoch erforderlich, diese Flächen durch Ölnuten gegen die Druckflüssigkeitsöffnung des Steuerspiegels abzugrenzen, uni ein Ausbreiten des Druckes über die ganze Fläche des Steuerspiegels zu vermeiden.The invention can be particularly advantageous in double-stroke piston engines be used. By. lift the symmetrical double-sided arrangement of the pistons the axial piston forces on each other in general. hur at the Ztt and If individual cylinders are switched off, residual forces can occur which are caused by a small Longitudinal ball bearings can be added. However, it has been shown to be useful special running surfaces are provided in the control plate to absorb these forces; , .s is then necessary, however, these surfaces through oil grooves against the hydraulic fluid opening of the control plate, uni spreading the pressure over the whole area to avoid the control plate.

Ein Anwendungsbeispiel der Erfindung ist in den Abbildungen dargestellt, und zwar stellt Abb. i einen lotrechten, Abb.2 einen wagerechten. Längsschnitt durch eine (loppcilitil)ige Kolbenmaschine dar, die mit einer Stettertt:ig gemäß der Erfindung ausgerüstet ist.An application example of the invention is shown in the figures, namely Fig. i represents a vertical, Fig.2 a horizontal. Longitudinal section through a (loppcilitil) ige piston engine, which is equipped with a Stettertt: ig according to the invention is equipped.

Auf der Welle i ist der Zylinderblock 2 aufgekeilt. Dieser Zylinderblock ist mit durchgehenden Zylinderbohrungen 3 versehen, die auf -einem ILreise um die Drehachse angeordnet sind. In den Zylindern arbeiten die Kolben ,4, die sich mit den Kolbenbolzen 3 gegen einen schräg gestellten mitumlaufenden Ring 6 abstützen. Die Zuflußleitungen 7 und Abflußleitungen 8 münden in den Steuerspiegeln g. Gegen diese Steuerspiegel legen sich die Steuerscheiben io, die sich mit dein Zylinderblock drehen und für jeden Zylinder eine Steueröffnung i i haben. Gegen den Zvliriderblock ist die Steuerscheibe durch Manschetten i2 abgedichtet. -Nuten 13 im Steuerspiegel verhindern ein Ausbreiten der Druckflüssigkeit über den ganzen Spiegel und grenzen Laufflächen 14 zur Aufnahme von Restkräften ab.The cylinder block 2 is keyed on the shaft i. This cylinder block is provided with through cylinder bores 3, which on a trip around the Rotation axis are arranged. The pistons work in the cylinders, 4 that work with support the piston pin 3 against an inclined rotating ring 6. The inflow lines 7 and outflow lines 8 open into the control plate g. Against These control mirrors put the control disks io, which are connected to your cylinder block turn and have a control port i i for each cylinder. Against the Zvliriderblock the control disk is sealed by sleeves i2. Grooves 13 in the control plate prevent the hydraulic fluid from spreading over the entire mirror and border Running surfaces 14 to absorb residual forces.
