Description
Gegenstand vorliegender Erfindung ist ein Flüssigkeitswechselgetriebe mit Kapselrädern, bei welchem durch axiales Verschieben der beiden Kapselzahnräder zueinander die aktiven Zahnbreiten verändert werden. Im Gegensatz zu bekannten Ausführungen solcher Getriebe sind gemäß der Erfindung die Hohlräume, die für das Verschieben des einen oder beider Zahnräder notwendig sind, mit Flüssigkeit gefüllt und durchThe present invention is a fluid change gearbox with capsule gears, at which by axially shifting the two capsule gears to each other the active tooth widths to be changed. In contrast to known designs of such transmissions are according to the invention, the cavities that are necessary for moving one or both gears are filled with liquid and through
ίο eine Ausgleichsbohrung miteinander verbunden. Hierdurch wird einmal erreicht, daß die Dichtungsflächen der die Hohlräume von den Zahnrädern trennenden Scheiben nur mit einem Druck belastet werden, der dem halben Druckunterschied zwischen der Druck- und der Saugseite entspricht; der Dichtungsspalt kann also gegenüber den früheren Ausführungen, wo er den ganzen Betriebsdruck auszuhalten hatte, etwas größer gewählt werden, wodurch sich der Reibungswiderstand beim Verschieben der Zahnräder wesentlich vermindert. Andererseits wird durch die Ausgleichsbohrung erreicht, daß das Verschieben der Zahnräder trotz der Füllung der Hohlräume ohne jede Schwierigkeit erfolgen kann, weil einer Verkleinerung des einen Raumes stets eine gleiche Vergrößerung des anderen entspricht. ίο a compensation hole connected to each other. This once ensures that the sealing surfaces of the cavities from the gears separating discs are only loaded with a pressure that is half the pressure difference corresponds between the pressure and the suction side; the sealing gap can therefore compared to the earlier versions, where he had to withstand the entire operating pressure, something be chosen larger, which increases the frictional resistance when moving the gears substantially reduced. On the other hand, the compensating bore ensures that the Moving the gears can be done without any difficulty in spite of the filling of the cavities because a reduction in one room always corresponds to an equal enlargement of the other.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt, und zwar zeigtIn the drawing, an embodiment of the invention is shown schematically, namely shows
Abb. I einen Axialschnitt durch ein derartiges Getriebe, während inFig. I shows an axial section through such a transmission, while in
Abb. 2 ein Querschnitt nach der Linie A-A in Abb. ι dargestellt ist.Fig. 2 is a cross section along the line AA in Fig. Ι is shown.
Die beiden miteinander in Eingriff stehenden Zahnräder sind mit ι und 2 bezeichnet. Das Zahnrad 2 ist auf einem zylindrischen Körper 3 drehbar gelagert. Dieser kann durch ein Ritzel 4 axial verschoben werden, wodurch die aktiven Zahnbreiten und somit die Liefermenge bzw. Schluckfähigkeit des Zahnradpaares in dem gegebenen Bereich beliebig verändert werden können. Auf der dem Ritzel 4 gegenüberliegenden Seite 5 ist der Körper 3 ausgespart, damit das Zahnrad ι durchlaufen kann. Die beiden Räume 6 und 7 an den Enden des Körpers 3 sind betriebsmäßig mit Flüssigkeit gefüllt und durch eine Ausgleichsbohrung 8 miteinander verbunden,The two gearwheels that are in engagement with one another are denoted by ι and 2. That Gear 2 is rotatably mounted on a cylindrical body 3. This can be done by a pinion 4 axially, whereby the active face widths and thus the delivery quantity or Swallowing ability of the gear pair in the given area can be changed as desired can. On the side 5 opposite the pinion 4, the body 3 is cut out so that the Gear ι can go through. The two spaces 6 and 7 at the ends of the body 3 are operational filled with liquid and connected to one another by a compensating bore 8,
