Die Lagerungsmittel 12,13,14 der Welle 5 sind in her-stands. The bearing means 12,13,14 of the shaft 5 are in 20 kömmlicher Weise direkt im Gehäuseteil 1 eingebaut. Dagegen sind nun die ähnlichen Lagerungsmittel 15,16,17 der Welle 620 installed directly in the housing part 1 in a conventional manner. On the other hand, there are now the similar bearing means 15,16,17 of the shaft 6 in einer Buchse 18 eingebaut, die im Gehäuseteil 3 dreh- und schiebebeweglich ist und einen Ringflansch 18a hat; dieser be-Die Erfindung betrifft einen Variator gemäss dem Oberbe- stimmt in seiner Anlage an einer Ringschulter 3a des Gehäusegriff des Patentanspruches 1. 25 teiles 3 diejenige Achsiallage der Buchse 18 und somit auch der Derartige sind in vielen Ausführungen bekannt, u.a. in sol- Welle 6, in welcher der Reibschluss der Reibkörper 10 mit den chen, bei denen die Reibkörper im wesentlichen kugelig sind, Reibrädern 7,8 gewährleistet ist.

Diese Veränderung kann 30 seinem Aussengewinde - vorzugsweise ein z.B. fünfgängiges aber bei allen bekannten Ausführungen nur während des Laufes Steilgewinde - in passendes, am Gehäuseteil 3 ausgebildetes erfolgen, da stets dafür gesorgt wird, dass schon im Stillstand ein Innengewinde, so dass eine Drehung der Buchse um z.B. nur gehöriger Reibschluss zwischen den Reibkörpern und den Reib- 30° genügt, um den Reibschluss zwischen den Reibkörpern 10 rädern vorgesehen sind, wenn gleich in den meisten Ausführen- und den Reibrädern 7,8 aufzuheben, damit danach die Verän-gen noch zusätzlich dafür gesorgt ist, dass sich im Betrieb dieser 35 derung des Übersetzungsverhältnisses des Variators auch bei Reibschluss automatisch an die Grösse des zu übertragenden stillstehenden Wellen 5,6 erfolgen kann.installed in a bushing 18 which is rotatable and slideable in the housing part 3 and has an annular flange 18a; This The invention relates to a variator according to the above-determined in its attachment to an annular shoulder 3a of the housing handle of patent claim 1. 25 part 3 that axial position of the bushing 18 and thus also such are known in many designs, including in sol- shaft 6, in which the frictional engagement of the friction bodies 10 with the surfaces in which the friction bodies are essentially spherical, friction wheels 7.8 is ensured. In addition to the annular flange 18a, in order to change the transmission ratio, the Nei- sits firmly on the bushing 18, a screw ring 19, on which a movement of their own axes to the common axis of the two adjusting element 20 is attached. The screw ring 19 engages with shafts and friction wheels is changed. This change can be made from its external thread - preferably a five-start thread, for example, but in all known designs only a high-helix thread during the run - to a suitable one formed on the housing part 3, since care is always taken to ensure that an internal thread is formed even when stationary, so that the bushing cannot rotate For example, proper frictional engagement between the friction bodies and the frictional 30° is sufficient to eliminate the frictional engagement between the frictional bodies 10 wheels, albeit in most execution and the friction wheels 7.8, so that the requirements are additional it is ensured that during operation of this 35 change in the transmission ratio of the variator, even in the case of frictional engagement, can be automatically adapted to the size of the stationary shafts 5.6 to be transmitted.

In itself, training would also be conceivable in which the Der Erfindung liegt nun die Aufgabe zugrunde, es mit ei- Verstellung der Buchse 18 nicht durch Verschrauben, sondern nem geringen zusätzlichen Bauaufwand zu ermöglichen, den er- z.B. auf hydraulischem Wege erfolgen würden, wobei z.B. der wähnten Reibschluss bei stillstehenden Wellen aufzuheben mit 40 Ringflansch 18a als Ringkolben arbeiten würde. Eine solche der Folge, dass auch im Stillstand das Übersetzungsverhältnis Ausführung wäre aber aufwendiger und weniger betriebssicher.The invention is now based on the object of making it possible with an adjustment of the bushing 18 not by screwing, but with a small additional construction effort, which would be done e.g. hydraulically, whereby e.g 18a would work as an annular piston. Such a consequence that the transmission ratio would also run at a standstill, but would be more complex and less reliable. CC 1 Blatt Zeichnungen1 sheet of drawings
