Kolben - Pleuelstangen - GelenkPistons - connecting rods - joint
Die Erfindung betrifft ein Kolben-Pleuelstangen-Gelenk, das sich besonders für hydrostatische Geräte eignet.The invention relates to a piston-connecting rod joint which is particularly suitable for hydrostatic devices.
Bekannt sind die Schwierigkeiten beim Verbinden von Gliedern hydrostatischer Geräte mit dem gewünschten Genauigkeitsgrad, die für die Übertragung einer Bewegung bestimmt sind.The difficulties in connecting links of hydrostatic devices with the desired degree of accuracy are known, which are intended for the transmission of a movement.
Vor allem erfordert die bewegliche Verbindung zwischen Pleuelstange und Kolben eine hohe Bearbeitungsgenauigkeit der zu paarenden Glieder, um etwaige Spiele zwischen beiden möglichst auszuschalten: nur so kann nämlich eine weitgehen-Above all, the movable connection between the connecting rod and the piston requires a high level of machining accuracy of the links to be paired in order to eliminate any play between the two as possible: only in this way can a far-reaching

de, getreue Wiedergabe der zu übertragenden Bewegungen erreicht werden. Diese erforderliche, hohe Genauigkeit beeinflußt aber in unzulässigem Maß die Herstellungskosten solcher Gelenke.de, faithful reproduction of the movements to be transmitted can be achieved. This required, high accuracy affects but to an inadmissible extent the manufacturing costs of such joints.
Zweck der Erfindung ist nun die Schaffung eines Kolben-Pleuelstangen-Gelenkes von besonders einfachem Zusammenbau, genauer Wirkungsweise und kostensparender Herstellung.The purpose of the invention is now to create a piston-connecting rod joint of particularly simple assembly, precise mode of operation and cost-saving production.
Dieser Zweck wird erfindungsgemäß durch Schaffung eines Kolben-Pleuelstangen-Gelenkes erreicht, bei dem die Pleuelstange zumindest an dem einen Ende, das sich mit dem Kolben paart, einen kugelig ausgebildeten Kopf aufweist, der in einen im wesentlichen hohlkugeligen, im Kolben ausgesparten Raum hineinpaßt, der auch einen größeren Abschnitt des Pleuelstangenkopfes aufnehmen kann und um seine Mündung eine Umfangsrille aufweist, die als Sitz für einen Festring dient, der durch eine im Kolben ausgesparte, zu der Rille tangential verlaufende Bohrung in dieselbe Rille eingeschoben wird, wobei der Innendurchmesser des Festringes kleiner als der Durchmesser des Pleuelstangenkopfes ist, so daß der Festring an einem unteren Kugelabschnitt des Pleuelstangenkopfes anliegt, um diesen in seinem Sitz zu halten.This purpose is achieved by providing a Piston-connecting rod joint achieved in which the connecting rod at least at one end that is with the piston pairs, has a spherical head which is recessed in a substantially hollow spherical head in the piston Space fits into it, which also takes up a larger portion of the connecting rod end can accommodate and has a circumferential groove around its mouth, which serves as a seat for a locking ring, which is inserted into the same groove through a bore cut out in the piston and running tangentially to the groove is, wherein the inner diameter of the locating ring is smaller than the diameter of the connecting rod end, so that the locating ring rests against a lower spherical section of the connecting rod head in order to hold it in its seat.
Naturgemäß kann auch für den anderen Kopf der Pleuelstange die gleiche Art Paarung vorgesehen werden, wie oben für die Verbindung mit dem Kolben.Of course, the same type of pairing can be provided for the other head of the connecting rod as for the above Connection with the piston.
Die Erfindung wird in der Folge anhand der beiliegenden Zeichnung näher erklärt, in der eine bevorzugte Ausführungsform derselben gezeigt wird. In der Zeichnung stellt The invention is explained in more detail below with reference to the accompanying drawing, in which a preferred embodiment of the same is shown. In the drawing represents

Das erfindungsgemäße Kolben-Pleuelstangen-Gelenk umfaßtThe piston-connecting rod joint according to the invention comprises
509809/0337509809/0337
einen Kolben 1 und eine Pleuelstange 2, die z.B. bei hydro-. statischen Geräten Anwendung finden können. Die Pleuelstange 2 weist an ihren Enden kugelförmig ausgebildete Köpfe 3 und H- auf, deren Durchmesser beide größer als der Durchmesser des restlichen Teiles der Pleuelstange sind. Der Kolben 1 besitzt eine zylindrische Bohrung 5, die in'einen halbkugeligen Hohlraum 6 ausläuft, der dem Pleuelstangenkopf 3 entspricht. Die Bohrung 5 ist außerdem mit einer Ringrille versehen, die an den Hohlraum 6 anschließt und so angeordnet ist, daß der Abstand vom Übergang des Hohlraumes 6 in die Bohrung 5 kürzer ist als der Halbmesser des Hohlraumes bzw. des halbkugelförmigen Pleuelstangenkopfes 3· Die'Rille 7 steht mit der Außenluft durch eine Bohrung 8 in Verbindung, deren Durchmesser gleich der Breite der Rille 7 ist. Die Bohrung 8 verläuft tangential zur Ringrille 7 und ist dazu bestimmt, das drahtförmige Teil 9 aus biegsamem Werkstoff mit praktisch gleichem Durchmesser wie die Breite der Ringrille 7 durchzulassen, welches den Pleuelstangenkopf 3 in seinem Sitz, d.h. im Hohlraum 6 zu halten hat.a piston 1 and a connecting rod 2, which, for example, with hydro. static devices can be used. The connecting rod 2 has spherical heads 3 and H- at its ends, the diameters of which are both larger than the diameter of the remaining part of the connecting rod. The piston 1 has a cylindrical bore 5 which ends in a hemispherical cavity 6 which corresponds to the connecting rod head 3. The bore 5 is also provided with an annular groove which adjoins the cavity 6 and is arranged so that the distance from the transition from the cavity 6 to the bore 5 is shorter than the radius of the cavity or of the hemispherical connecting rod head 3 · Die'Rille 7 communicates with the outside air through a bore 8, the diameter of which is equal to the width of the groove 7. The bore 8 runs tangentially to the annular groove 7 and is intended to let through the wire-shaped part 9 made of flexible material with practically the same diameter as the width of the annular groove 7, which has to hold the connecting rod head 3 in its seat, ie in the cavity 6.
Der Zusammenbau des Kolben-Pleuelstangen-Gelenkes erfolgt wie nachstehend beschrieben:The assembly of the piston-connecting rod joint is carried out as described below:
Die Pleuelstange 2 wird mit ihrem Kopf 3 in die zylinderförmige Bohrung 5 des Kolbens 1 eingeführt, der Kopf 3 in den halbkugeligen Hohlraum 6 gelegt und darin gehalten. Dann wird das drahtförmige Teil 9 durch die Bohrung 8 in die Ringrille 7 eingeschoben, so daß es den Pleuelstangenkopf 3 in seinem Sitz 6 hält.The connecting rod 2 is with its head 3 in the cylindrical Bore 5 of piston 1 inserted, head 3 in placed the hemispherical cavity 6 and held therein. Then the wire-shaped part 9 is inserted through the bore 8 in the annular groove 7 is inserted so that it holds the connecting rod head 3 in its seat 6.
Die sich aus dem erfindungsgemäßen Kolben-Pleuelstangen-Gelenk ergebende Verbindung ist deswegen besonders sicher, weil sich der Pleuelstangenkopf 3 durch die Wirkung des drahtförmigen Teils 9 genau anschmiegt.The result of the piston-connecting rod joint according to the invention The resulting connection is particularly secure because the connecting rod head 3 is due to the action of the wire-shaped part 9 fits snugly.
Der Querschnitt des drahtförmigen Teils 9 kann anders ausgebildet sein als kreisrund, wie z.B. in Fig. 3 mit dem Teil 10 gezeigt.The cross section of the wire-shaped part 9 can be designed differently be as circular, as shown for example in Fig. 3 with part 10.
Der Kolbenkopf kann mit einer Einfetteinrichtung zur Schmierung des Pleuelstangenkopfes versehen sein.The piston head can be lubricated with a greasing device of the connecting rod end.
509809/0337509809/0337
Die gleiche Art beweglicher Verbindung kann auch zur Vereinigung
des entgegengesetzten Pleuelstangenkopfes z.B.
rnib einem Antriebsgleitschuh vorgesehen werden, welche Verbindungsart
jedoch in Frage kommt, wenn die Paarung eines kugeligen Kopfes mit einem entsprechenden Hohlraum erforderlich
ist.The same type of movable connection can also be used to unite the opposite connecting rod end, for example
rnib a drive sliding shoe, which type of connection is possible, however, if the pairing of a spherical head with a corresponding cavity is required.
