Description

Bei den bekanntgewordenen Kolbenmaschinen mit Hypozykloidengetriebe läuft in einem feststehenden Innenzahnkranz ein außenverzahntes Rad mit halbem Teilkreisdurchmesser; das auf einem Kurbelarm drehbar angeordnet ist, wobei ein Punkt auf dem Teilkreis einen Kurbelzapfen trägt, der in Verbindung mit einer Kolbenstange einen Kolben -in einem zugeordneten Zylinder hin und her bewegt.In the well-known piston machines with hypocycloidal gears An externally toothed wheel with half the pitch circle diameter runs in a fixed internal gear rim; which is rotatably arranged on a crank arm, with a point on the pitch circle carries a crank pin which, in conjunction with a piston rod, has a piston Moved back and forth in an assigned cylinder.

Ferner ist es bekannt, für jeden solchen einfach oder doppelt wirkenden Kolben, symmetrisch zur Zylinderachse, je ein solches Hypozykloidengetriebe vorzusehen, dem zum Ausgleich der hin und her gehenden Massen noch je ein weiteres Hypozykloidengetriebe zugeordnet wird, dessen Zahnrad diametral gegenüber dem Kurbelzapfen ein Gegengewicht trägt.It is also known for any such single or double acting Pistons, symmetrical to the cylinder axis, each have such a hypocycloidal gear to be provided, to compensate for the masses going back and forth, a further hypocycloid gear is assigned, the gear wheel diametrically opposite the crank pin a counterweight wearing.

Durch Fehlen eines Kreuzkopfes beim Hypozykloidengetriebe wird eine kurze Bauform erzielt, die die doppelt wirkende Arbeitsweise bei Kolbenmaschinen besonders begünstigt.The lack of a cross head in the hypocycloidal gear causes a short design achieved that the double-acting mode of operation in piston engines particularly favored.

Erfindungsgemäß kann auch bei Kolbenmaschinen mit Hypozykloidengetriebe die V-förmige Zylinderanordnung angewendet werden, die in diesem Zusammenhange noch nicht bekanntgeworden ist, aber durch ihren gedrungenen Aufbau besondere Vorteile bietet.According to the invention, piston engines with hypocycloidal gears can also be used the V-shaped cylinder arrangement can be used in this context has not become known, but has special advantages due to its compact structure offers.

Gemäß Abb. i und 2 rollen in den feststehenden Innenzahnkränzen i die außenverzahnten Räder 2, mit halbem Teilkreisdurchmesser der ersteren, ab, wobei sie von den Kurbelarmen g geführt werden. 'Mit den Zahnrädern 2 ist eine in diesem Falle zweifach gekröpfte Kurbel 3 so verbunden, daß die Achsen der Kurbelzapfen 3 die Teilkreise der Zahnräder 2 schneiden.According to fig. I and 2 roll in the fixed internal gear rims i the externally toothed wheels 2, with half the pitch circle diameter of the former, from, where they are guided by the crank arms g. 'With the gears 2 there is one in this Case double cranked crank 3 connected so that the axes of the crank pin 3 cut the pitch circles of the gears 2.

Der Winkel 2 a, den die Kurbelzapfen 3 miteinander einschließen, ist doppelt so groß wie der Winkel x, den die beiden diesen Kurbeln zugeordneten Zvlinderachsen miteinander bilden. Beim Abrollen der Zahnräder 2 bewegen sich die Lager 4 der Kolbenstangen 5 auf den Achsen der dazugehörigen Zylinder.The angle 2 a, which the crank pin 3 enclose with each other, is twice as large as the angle x between the two cylinder axes assigned to these cranks form with each other. When the gears 2 roll, the bearings 4 of the piston rods move 5 on the axes of the associated cylinders.

Zum Massenausgleich der Zahnräder 2 und Kurbeln 3 usw. können Gegengewichte 12 vorgesehen werden.To balance the masses of the gears 2 and cranks 3, etc., counterweights 12 are provided.

Für je zwei oder mehr Zylinder in V-Form werden demnach nur zwei Hypozykloidengetriebe benötigt, doch ist, wie bei der Reihenanordnung der Zylinder, auch bei der V-Form die Anordnung von je zwei Hypozykloidengetrieben für einen Zylinder möglich.For every two or more cylinders in V-shape, only two hypocycloidal gears are required is required, but is, as with the in-line arrangement of the cylinders, also with the V-shape the arrangement of two hypocycloid gears for each cylinder is possible.

In Umkehrung der Verhältnisse kann sich bei der oben beschriebenen Kolbenmaschine mit Hypozykloidengetriebe auch der Innenzahnkranz gleichzeitig mit den Zylindern um die Hauptachse drehen, während die Kurbelarme 9 mit den Zahnrädern 2 stehenbleiben (Umlaufmotor).The reverse of the situation can be found in the case of the one described above Piston machine with hypocycloid gear also the internal ring gear at the same time the cylinders rotate around the main axis, while the crank arms 9 with the gears 2 stop (rotary motor).

Bei Kapselung der Triebwerksräder ergeben sich umlaufende Zahnradpumpen, die für die Schmieröl-oder Luftförderung dienen können.Encapsulation of the engine wheels results in rotating gear pumps, which can be used for lubricating oil or air pumping.
