Description

Verdichter oder Expansionskraftmaschine nach Art einer Zahnradpumpe. Es sind als Verdichter oder Expansionskraftmaschinen verwendbare Maschinen bekannt, deren wesentlicher Teil wie bei den bekanntenZahnradpumpen einZahnräderpaar ist, bei denen jedoch im Gegensatz zu den bekannten Zahnradpumpen ein außen verzahntes (inneres) und ein innen verzahntes (äußeres) Rad verwendet wird und bei denen die Verzahnung so konstruiert ist, daß eine das innere Rad ganz umfassende Eingriffslinie existiert. Diese Eigenschaft hat z. B. eine Zykloidenverzahnung, wenn die Summe der Wälzkreisdurchmesser gleich der doppelten Exzentrizität ist. Macht man bei dieser Verzahnung außerdem die Zähnezahl des einen Rades um i kleiner als die des äußeren, so erstreckt sich der Eingriff bei spielfreier Verzahnung über die ganze Eingriffslinie, und es ist jeder Zahn des inneren Rades gleichzeitig mit einem Zahn des äußeren Rades in Eingriff.Compressor or expansion engine in the manner of a gear pump. Machines that can be used as compressors or expansion engines are known, the essential part of which is a pair of gears, as is the case with the known gear pumps, in which, however, in contrast to the known gear pumps, an externally toothed one (inner) and an internally toothed (outer) wheel is used and where the The toothing is designed in such a way that a line of contact that completely encompasses the inner wheel exists. This property has z. B. a cycloid toothing, if the sum the Pitch circle diameter is equal to twice the eccentricity. With this toothing, the number of teeth on one wheel is also reduced by i than that of the outer, the engagement extends over with backlash-free teeth the whole line of action, and it is every tooth of the inner gear at the same time with meshed with a tooth of the outer wheel.

Eine solche Verzahnung zeigt beispielsweise die Abb. r. Hier ist cc, das innere Rad mit dem Mittelpunkt M, und dem Teilkreis t, d2 das äußere Rad mit dem Mittelpunkt M, und dem Teilkreis t.. e ist die das innere Rad ganz umfassende Eingriffslinie, auf der die sechs Eingriffspunkte El bis E, liegen. Durch diese Eingriffspunkte werden die sechs Arbeitsräume r' bis y6 voneinander getrennt.Such a toothing is shown, for example, in Fig. R. Here is cc, the inner wheel with the center M, and the pitch circle t, d2 the outer wheel with the center M, and the pitch circle t .. e is the line of action that encompasses the inner wheel and on which the six points of engagement El to E , lie. The six working spaces r 'to y6 are separated from one another by these intervention points.

Die bauliche Ausbildung und Herstellung einer Maschine der im vorstehenden beschriebenen Art ist dadurch erschwert, daß ein Rad mit Innenverzahnung nicht in gleicheinfacher Weise wie ein außen verzahntes Rad durch Fräsen hergestellt werden kann. Diese Schwierigkeit kann erfindungsgemäß dadurch beseitigt werden, daß die Zähne des äußeren Rades einzeln hergestellt und eingesetzt werden.The structural design and manufacture of a machine in the above The type described is made more difficult by the fact that a wheel with internal teeth is not in in the same simple way as an externally toothed wheel can be manufactured by milling can. This difficulty can be eliminated according to the invention in that the Teeth of the outer wheel are individually manufactured and used.

Eine weitere Schwierigkeit liegt darin, daß bei der spielfreien Ausführung der Verzahnung, wie sie in Abb. i dargestellt ist, eine außerordentlich genaue Arbeit erforderlich ist, um ein Klemmen der Räder zu verhindern. Wenn aber die Zähne des äußeren Rades einzeln eingesetzt sind, kann auch diese Schwierigkeit dadurch beseitigt werden, daß erfindungsgemäß die Zähne des äußeren Rades federnd gelagert werden. Für diese Lagerung genügt schon eine Lage einfach aufeinandergeschichteter Bleche unter den eingesetzten Zähnen des äußeren Rades. Die Abb. a zeigt beispielsweise eine solche Bauart des äußeren Rades. Hier sind mit d die eingesetzten Zähne bezeichnet, mit f die federnden Bleche, auf welchen die Zähne aufliegen, mit h der äußere Ring, der das Ganze zusammenhält.Another difficulty lies in the fact that the backlash-free execution the toothing, as shown in Fig. i, is an extremely precise job is necessary to prevent the wheels from jamming. But if the teeth of the outer wheel are used individually, this problem can also be eliminated that according to the invention the teeth of the outer wheel are resiliently mounted. One layer of sheets simply stacked on top of one another is sufficient for this storage under the inserted teeth of the outer wheel. For example, Fig. A shows such a design of the outer wheel. Here the inserted teeth are designated with d, with f the resilient metal sheets on which the teeth rest, with h the outer ring, that holds the whole thing together.
