Description

Flüssigkeitswechselgetriebe. Die Erfindung betrifft ein Flüssigkeitswechselgetriebe mit umlaufenden Arbeitszylindern, bei dem die Kolbenbewegung durch eine exzentrisch angeordnete Rollbahn hervorgerufen wird. Es ist schon bekannt, bei derartigen Flüssigkeitswechselgetrieben die Arbeitskolben mit Führungsro_len zu versehen. Es hat sich nun aber herausgestellt, daß diese Führungsrollen einer starken Abnutzung unterworfen sind mit Rücksicht darauf, daß infolge des hohen Flüssigkeitsdruckes die Rollen stark belastet werden und daß auch anderseits das Getriebe mit einer hohen Drehzahl umläuft. Hoher FFüssigkeitsdruck und hohe Umlaufzahlen sind aber für derartige Flüssigkeitsgetriebe Grundbedingung, um sie in verhältnismäßig kleinen Abmessungen herstellen zu können.Fluid change gear. The invention relates to a fluid change transmission with rotating working cylinders, in which the piston movement is controlled by an eccentric arranged runway is caused. It is already known in such fluid change gears to provide the working pistons with guide rollers. But it has now turned out that these guide rollers are subject to severe wear with consideration on the fact that the roles are heavily loaded due to the high pressure of the liquid and that on the other hand, the gearbox rotates at a high speed. High fluid pressure and high numbers of revolutions are a basic requirement for such fluid transmissions, in order to be able to produce them in relatively small dimensions.

Durch die vorliegende Erfindung werden diese Nachteile vermieden, indem die Sch:upfdiehzahlder Rollen soweit wie möglich verringert wird. Das wird dadurch erreicht, daß die Roll- oder Führungsbahn, gegen welche sich die Führungsrollen legen, so leicht beweglich gelagert ist, daß die Rollbahn fast die volle Umfangsgeschwindigkeit des Zylindersterns annimmt, so daß dadurch die Schlupfdrehzahl der Rollen wesentlich verringert wird.The present invention avoids these disadvantages, by reducing the speed of the roles as much as possible. That will achieved in that the roller or guide track against which the guide rollers place, is so easily movable that the runway is almost the full circumferential speed of the cylinder star assumes, so that thereby the slip speed of the rollers is essential is decreased.

Man hat schon bei Maschinen mit umlaufenden Arbeitszylindern, die insbesondere als Luftverdichter verwendet werden, den Führungsring für die Rollen der Arbeitskolben lose drehbar gelagert. Man wollte aber hier durch die lose Drehung eine wesentliche Phasenverschiebung zwischen den umlaufenden Zylindern und dem Ring herbeiführen, um eine ungleichmäßige Abnutzung des Ringes zu vermeiden. Die bei dieser Anordnung auftretenden Umdrehungszahlen der Führungsrollen sind aber für die mit hohem Druck arbeitenden Flüssigkeitsgetriebe noch viel zu hoch. Erst durch die oben angegebene Verbesserung der Einrichtung wird ein einwandfreies Arbeiten der Führungsrollen bei ganz geringer Schlupfdrehzahl ermöglicht.One already has in machines with rotating working cylinders that be used in particular as an air compressor, the guide ring for the rollers the working piston is loosely rotatably mounted. But here you wanted to go through the loose rotation a substantial phase shift between the rotating cylinders and the ring to avoid uneven wear of the ring. The at However, the number of revolutions of the guide rollers occurring in this arrangement is for the fluid gears working at high pressure are still much too high. Only by the above improvement of the facility will be a flawless working the guide rollers at a very low slip speed.

Auf der Zeichnung ist ein Längsschnitt durch ein derartiges Flüssigkeitswechselgetriebe dargestellt.In the drawing is a longitudinal section through such a fluid change gear shown.

In dem Gehäuse i ist der Zylinderb'.ock z gelagert, in welchem die Zylinder ausgespart sind, in denen sich die Kolben 3 verschieben. Die Kolben tragen an ihrem Ende Führungsrollen 7, welche sich gegen den lose drehbar gelagerten Ring oder die Trommel 8 legen, so daß beim Umlaufen des Getriebes auch die Trommel 8 mit umläuft und die Rollen 7 nur geringe Schwingungsbewegungen ausführen.In the housing i, the cylinder bracket z is mounted, in which the Cylinders are recessed, in which the pistons 3 move. Wear the pistons at its end guide rollers 7, which are against the loosely rotatably mounted ring or place the drum 8 so that the drum 8 rotates with and the rollers 7 only perform small oscillating movements.
