Description
Den Gegenstand des Hauptpatents bildet eine Drehkolbenmaschine mit zwei ellipsenähnlichen, sich um ihre Mittelachse drehenden und aufeinander ablaufenden zylindrischem S Kolben. Das Kennzeichen des Anspruchs 1 des Hauptpatents besteht darin, daß die Kolben unmittelbar miteinander verzahnt sind. Das Kennzeichen der Maschine nach Anspruch 2 des Hauptpatents ist die besondere Form der Teilkurven der Kolben, welche aus den zugehörigen Ellipsen auf eine besondere Art erhalten wird.The subject of the main patent is a rotary piston machine with two elliptical, rotating around its central axis and running off one another cylindrical S piston. The characteristic of claim 1 of the main patent is that the piston are directly intermeshed with one another. The identification of the machine according to claim 2 of the main patent is the special shape of the partial curves of the pistons, which from the associated ellipses to a special Kind is obtained.
Den Gegenstand des vorliegenden Zusatzpatents bildet eine andere AusführungsformAnother embodiment forms the subject of the present additional patent
der Drehkolbenmaschine nach Anspruch 2 des Hauptpatents, bei welcher die ellipsenähnlichen Kolben in an sich bekannter Weise glatte Umfange besitzen und mit diesen aufeinander ablaufen, während die zwangsläufige Verbindung der Kolben durch außerhalb des Gehäuses auf den Wellen derselben sitzende ellipsenähnliche Zahnräder bewirkt wird, deren Teilkurven mit den Umfangen der Drehkolben kongruent sind und mit diesen zusammenfallen. the rotary piston machine according to claim 2 of the main patent, in which the ellipse-like Pistons have smooth circumferences in a manner known per se and with these one on top of the other expire, while the inevitable connection of the piston by sitting on the shafts of the same outside of the housing ellipse-like gears are effected, whose part curves with the circumference of the rotary piston are congruent and coincide with them.
Bei bereits bekanntgewordenen Maschinen ähnlicher Art, bei welchen ellipsenähnliche Kolben mit ihren glatten Umfangen aufeinander abrollen und die zwangsläufige Verbindung der Kolben durch außerhalb des Gehäuses sitzende Zahnräder bewirkt wird, sind die Zahnräder zylindrische Stirnräder. Mit solchen Zahnrädern kann aber nur eine Drehung der ellipsenähnlichen Kolben mit gleicher Winkelgeschwindigkeit, aber niemals mit gleicher Umfangsgeschwindigkeit erzielt werden, wie dies in dem vorliegenden Falle angestrebt wird. Im ersteren Falle muß eine Relativbewegung der Umfange der Kolben aufeinander erfolgen, wodurch Abnutzung derselben entsteht. In dem letzteren Falle ist die Bewegung der Kolben aufeinander ein einwandfreies Abrollen. Der Antrieb der ellipsenähnlichen Kolben mit Verdickungen nach Anpruch 2 des Hauptpatents kann also in einwandfreier Weise nur durch ellipsenähnliche _ Zahnräder erfolgen, deren Teilkreise mit den Umfangen der Kolben kongruent sind.In machines of a similar type that have already become known, in which elliptical-like ones Pistons roll on each other with their smooth circumference and the inevitable connection the piston is caused by gears located outside the housing, the gears are cylindrical spur gears. With Such gears can only rotate the elliptical piston with the same Angular speed, but never with the same peripheral speed, how this is sought in the present case. In the former case there must be a relative movement the circumference of the pistons are carried out on top of each other, causing wear and tear of the same arises. In the latter case the movement of the pistons towards one another is perfect Unroll. The drive of the elliptical piston with thickening according to claim 2 of the main patent can therefore only be flawlessly achieved through ellipse-like _ Gears are made whose pitch circles are congruent with the circumference of the piston.
Daß die Antriebsräder nach außen verlegt und die Kolben mit glatten Umfangen versehen werden, hat seinen Grund darin, daß z.B. bei angreifenden Säuren,für die Kolben ein äußerst harter Werkstoff, wie z.B. Wolframcarbid, gewählt werden muß, der säurebeständig ist. Ein solcher Werkstoff gestattet aber das Fräsen der Zähne nicht mehr, wohl aber das Schleifen glatter Umfange. Es wurde also der Kunstgriff benutzt, die KoI-That the drive wheels moved outwards and provided the pistons with smooth circumferences is due to the fact that e.g. in the case of aggressive acids, for the pistons an extremely hard material, such as tungsten carbide, must be selected which is acid-resistant is. Such a material no longer allows the teeth to be milled, but allows smooth circumferences to be ground. It So the trick was used, the KoI-

Die Kolben c und d, die sich in dem Gehäuse α drehen, sind an ihren Umfangen glatt und rollen aufeinander ab. genau so wie die Teilkurven der gezahnten, ellipsenähnlichen Kolben nach dem Hauptpatent. Die Wellen ι und 2 der Drehkolben c und d gehen durch einen Deckel3 des Gehäuses« hindurch und tragen oberhalb dieses Deckels 3 zwei ellipsenähnliche Zahnräder 4 und 5, deren. Teilkurven 6 und 7 den Umfangen der Kolben c und d kongruent sind und mit diesen zusammenfallen. Durch diese Zahnräder 4 und 5 wird die zwangsläufige Bewegung der glatten Kolben c und d in derselben Weise erzielt wie nach dem Hauptpatent durch die unmittelbare Verzahnung der beiden Kolben.The pistons c and d, which rotate in the housing α , are smooth on their peripheries and roll off one another. just like the part curves of the toothed, ellipse-like pistons according to the main patent. The shafts ι and 2 of the rotary piston c and d go through a cover 3 of the housing "and above this cover 3 carry two elliptical gears 4 and 5, their. Partial curves 6 and 7 are congruent to the circumference of the pistons c and d and coincide with them. Through these gears 4 and 5, the inevitable movement of the smooth pistons c and d is achieved in the same way as according to the main patent through the direct toothing of the two pistons.
