Description
Die Erfindung betrifft Drehventilantriebe für hydrstatische Zahnrad-Kreiskolbenmotoren , bei denen sogenannte Taumelhülsen verwender werden zur Übertragung der Drehzahl des Kreiskolbens um seine eigene Achse auf das kommutierende Drehventil. Hierbei ist zu beachten, dass das Drehventil eine zentrische Drehbewegung bezüglich des Srators der Kreiskolbenmaschine ausübt. Da der Kreiskolben eine Orbitbewegung ausführt gegenüber dem Stator, muss ein Verbindungrorgan verwendet werden, das eine Taumelbewegung ausführt, um die Exzentrizität des Kreiskolbens zu überbrücken.The invention relates to rotary valve actuators for hydromatic geared rotary piston engines in which so-called wobble sleeves are used for transmitting the rotational speed of the rotary piston about its own axis to the commutating rotary valve. It should be noted that the rotary valve exerts a centric rotational movement with respect to the stator of the rotary piston engine. Since the rotary piston makes an orbital movement with respect to the stator, it is necessary to use a connecting element that performs a wobbling motion in order to bridge the eccentricity of the rotary piston.
In dem Falle, dass dieses taumelnde Organ direkt den Kreiskolben mit dem Drehventil drehzahlwirksam verbindet, wird der Taumelwinkel verhältnismäßig gross entsprechend der Exzentrizität (Achsabstand) des Kreiskolbens zum Stator.In the event that this tumbling member directly connects the rotary piston with the rotary valve effective speed, the wobble angle is relatively large according to the eccentricity (center distance) of the rotary piston to the stator.
In einem anderen Fall, bei dem aus Gründen der Lagerung der Abtriebswelle die direkte Verbindung nicht möglich ist, ist ein Exzentergetriebe vorgesehen, das die entsprechende Drehzahlübersetzung zwischen dem Kreiskolben und dem Drehventil erzeugt. Aber auch dort muss das übertragende Organ von dem sich exzentrisch bewegende Teil des Exzentergetriebes eine, wenn auch meistens kleinere Taumelbewegung ausführen.In another case, in which for reasons of storage of the output shaft, the direct connection is not possible, an eccentric is provided which generates the corresponding speed ratio between the rotary piston and the rotary valve. But even there, the transmitting organ of the eccentric moving part of the Exzentergetriebes has to perform a, albeit usually smaller tumbling motion.
Ziel der Erfindung ist, den erforderlichen Taumelwinkel so klein wie möglich zu machen, da dieser die Dauerfestigkeit der jeweiligen übertragenden Verzahnungen beeinflußt. Ferner ist bei grossem Taumelwinkel ein grösseres Zahnspiel notwendig, damit in der Beweglichkeit keine Zwänge entstehen.The aim of the invention is to make the required wobble angle as small as possible, as this affects the fatigue strength of the respective transmitting teeth. Furthermore, a large backlash is necessary with a large wobble angle, so that no constraints arise in the mobility.
