Description

Die Erfindung betrifft eine Vorrichtung zur Umwandlung einer hin- und hergehenden Bewegung in eine Drehbewegung und umgekehrt.The invention relates to a device for converting a reciprocating motion into a rotary motion and vice versa.

Bekannt ist eine derartige Umwandlung mit Hilfe einer Kurbelwelle und einem Pleuel, wobei Kurbelwelle und Pleuel für einen bestimmten Hub ausgebildet sind.Such a conversion is known with the aid of a crankshaft and a connecting rod, wherein crankshaft and connecting rods are designed for a particular stroke.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung der eingangs genannten Art vorzuschlagen, die in einfacher Weise an unterschiedliche Hübe anpassbar ist.The object of the invention is to propose a device of the type mentioned, which is adaptable to different strokes in a simple manner.

Zur Lösung dieser Aufgabe werden zwei im Abstand zueinander angeordnete, sich kreuzende Steuerstangen vorgeschlagen, die in ihrer Längsrichtung hin- und herschiebbar gelagert sind, einen zwischen den Steuerstangen angeordneten Zahnreif mit einer Außenverzahnung und mit einer Innenverzahnung, in dessen Außenverzahnung vier im gleichen Abstand zueinander angeordnete, auf Abtriebswellen sitzende Abtriebszahnräder eingreifen, und ein in die Innenverzahnung des Zahnreifes eingreifendes Umlaufzahnrad, das zwei einander diametral gegenüberliegende Lager hat, wobei ein Lager mit der einen Steuerstange und das andere Lager mit der anderen Steuerstange zusammenwirkt.To solve this problem, two mutually spaced, intersecting control rods are proposed, which are mounted back and forth in their longitudinal direction, arranged between the control rods and a toothed wheel with external teeth with an internal toothing, arranged in the outer toothing four at the same distance from each other engaging output shafts seated on output shafts, and a recirculating gear meshing with the internal teeth of the serrated wheel having two diametrically opposed bearings, one bearing cooperating with the one control rod and the other bearing cooperating with the other control rod.

Vorteilhaft sind die Steuerstangen an ihren Endabschnitten in Lagern verschiebbar.Advantageously, the control rods are displaceable at their end portions in bearings.

Bei einer vorteilhaften Ausführungsform sind die Steuerstangen an ihren Endabschnitten mit in Zylindern gelagerten Kolben versehen.In an advantageous embodiment, the control rods are provided at their end portions with cylinders mounted in pistons.

Die Erfindung ist in den Zeichnungen beispielhaft dargestellt.The invention is illustrated by way of example in the drawings.

Nach den Fig. 1 bis 8 sind zwei im Abstand zueinander stehende Steuerstangen 1 und 2 sich im rechten Winkel kreuzend zueinander angeordnet. Die Steuerstangen 1 und 2 liegen in im Abstand und parallel zueinander verlaufenden Ebenen.According to FIGS. 1 to 8 two mutually spaced control rods 1 and 2 are arranged at right angles crossing each other. The control rods 1 and 2 are in spaced and parallel planes.

Im Raum zwischen den Steuerstangen 1 und 2 ist ein Zahnreif 3 angeordnet, der eine Innenverzahnung und eine Außenverzahnung trägt. In die Außenverzahnung des Zahnreifes 3 greifen vier in gleichem Abstand, paarweise einander diametral gegenüberliegende Abtriebszahnräder 4 ein, die auf nicht dargestellten Abriebswellen sitzen. Die Abtriebszahnräder 4 lagern den zwischen den Steuerstangen 1 und 2 geführten Zahnreif 3.In the space between the control rods 1 and 2, a toothed wheel 3 is arranged, which carries an internal toothing and an external toothing. In the outer toothing of the toothed wheel 3 engage four at the same distance, in pairs diametrically opposed output gears 4, sitting on not shown wear shafts. The driven gears 4 support the guided between the control rods 1 and 2 3 toothed wheel.

In die Innenverzahlung des Zahnreifes 3 greift ein Umlaufzahnrad 5 ein, das zwei zu seinem Mittelpunkt im Abstand einander diametral gegenüberliegende Lager 6 und 7 hat. Das Lager 6 wirkt mit der Steuerstange 1 zusammen, während das Lager 7 mit der Steuerstange 2 zusammenwirk. Die Lager 6 und 7 können in bekannter Weise ausgebildet sein, wobei die Lagerzapfen entweder an den Steuerstangen 1 und 2 angeordnet sind oder am Umlaufzahnrad 5.In the Innenverzahlung of the toothed wheel 3 engages a planetary gear 5, which has two diametrically opposite to its center at a distance bearing 6 and 7. The bearing 6 cooperates with the control rod 1, while the bearing 7 cooperates with the control rod 2. The bearings 6 and 7 may be formed in a known manner, wherein the bearing pins are arranged either on the control rods 1 and 2 or on the peripheral gear. 5

Bei der Vorrichtung nach den Figuren 1 bis 5 tragen die Steuerstangen 1 und 2 an ihren Enden Kolben 8, die in zugeordneten Zylindern 9 geführt sind, so dass sich ein Vierzylinder-Motor ergibt, beispielsweise mit einem Hub von 50 mm. Die eingezeichneten Pfeile geben die jeweilige Bewegungsrichtung bzw. Drehrichtung des Elementes an.In the apparatus according to Figures 1 to 5 carry the control rods 1 and 2 at their ends piston 8, which are guided in associated cylinders 9, so that there is a four-cylinder engine, for example with a stroke of 50 mm. The arrows indicate the respective direction of movement or direction of rotation of the element.

Wird in Fig. 1 die Steuerstange 1 nach unten bewegt, so dreht sich das Umlaufzahnrad 5 im Uhrzeigersinn um die Lager 6 und 7 in die in Fig. 2 dargestellte Stellung. Dadurch wird der Zahnreif 3 gleichfalls im Uhrzeigersinn gedreht, was eine Drehung der Abtriebszahnräder 4 im Gegenuhrzeigersinn bewirkt. Wird dann anschließend die Steuerstange 2 nach rechts bewegt, so dreht sich das Umlaufzahnrad 5 weiter in die in Fig. 3 dargestellte Stellung und weiter in die in Fig. 4 dargestellte Stellung. Wird dann die Steuerstange 1 nach oben bewegt, so gelangt das Umlaufzahnrad 5 in die in Fig. 5 dargestellte Stellung. Dieser Vorgang wird dann weitergeführt, bis die Vorrichtung wieder in der in Fig. 1 dargestellten Stellung ist, so dass ein vollständiger Zyklus vorliegt.In Fig. 1, the control rod 1 is moved downward, the planetary gear 5 rotates clockwise about the bearings 6 and 7 in the position shown in Fig. 2. As a result, the cog wheel 3 is also rotated in a clockwise direction, causing counterclockwise rotation of the driven gears 4. Then, then, the control rod 2 is moved to the right, then the planetary gear 5 rotates further into the position shown in Fig. 3 and further into the position shown in Fig. 4. If the control rod 1 is then moved upwards, then the circulating gear 5 reaches the position shown in FIG. This process is then continued until the device is again in the position shown in Fig. 1, so that there is a complete cycle.

Bei einer Ausführungsform der Vorrichtung nach Fig. 6 ist die Steuerstange 1 nur an einem Ende mit einem Zylinder 9 geführten Kolben 8 versehen, während der andere Endabschnitt und die Endabschnitte der Steuerstange 2 in Führungsbuchsen 10 geführt sind, so dass sich ein Einzylinder-Motor mit beispielsweise einem Hub von 40 mm ergibt.In one embodiment of the device according to Fig. 6, the control rod 1 is provided only at one end with a cylinder 9 guided piston 8, while the other end portion and the end portions of the control rod 2 are guided in guide bushes 10, so that a single-cylinder engine with For example, results in a stroke of 40 mm.

Bei der Ausführungsform der Vorrichtung nach Fig. 7 ist die Steuerstange 2 an ihren Enden mit in Zylindern 9 geführten Kolben 8 versehen, während die Endabschnitt der Steuerstange 1 in Führungsbuchsen 10 geführt sind. Somit ergibt sich ein Zweizylinder-Boxermotor, beispielsweise mit einem Hub von 32 mm.In the embodiment of the apparatus of FIG. 7, the control rod 2 is provided at its ends with guided in cylinders 9 piston 8, while the end portion of the control rod 1 are guided in guide bushes 10. This results in a two-cylinder boxer engine, for example with a stroke of 32 mm.

Bei der Ausführungsform der Vorrichtung nach Fig. 8 ist jeweils ein Ende der Steuerstangen 1 und 2 mit einem in Zylindern 9 geführten Kolben 8 versehen, während die anderen Enden der Steuerstangen in Führungsbuchsen 10 geführt sind, so dass sich ein Zweizylinder-V-Motor, beispielsweise mit einem Hub von 25 mm ergibt.In the embodiment of the apparatus of Fig. 8, one end of the control rods 1 and 2 is provided with a piston 8 guided in cylinders 9, while the other ends of the control rods are guided in guide bushes 10, so that a two-cylinder V-engine, for example, with a stroke of 25 mm results.

Wie die Figuren 6 bis 8 zeigen, eignet sich die Vorrichtung für verschiedene Zylinderanordnungen. Möglich ist es auch, die Steuerstangen 1 und 2 auf der Antriebsseite jeweils mit Doppelkolben zu bestücken und somit gleichzeitig mehrere Zylinder betreiben zu können.As FIGS. 6 to 8 show, the device is suitable for various cylinder arrangements. It is also possible to equip the control rods 1 and 2 on the drive side each with double piston and thus to be able to operate several cylinders simultaneously.

Der Hub der Steuerstangen 1 und 2 ist innerhalb weiter Grenzen - diese sind nur vom Innenradius des Zahnreifes 3 abhängig - frei veränderbar. Wird der Hub verkleinert, indem der Abstand der Lager 6 und 7 verringert wird, so muss lediglich der Durchmesser des Umlaufzahnrades 5 proportional vergrößert werden. Wird auch die Antriebsseite der Steuerstangen 1 und 2 entsprechend verändert, so können sogar gleiche Zylinder mit unterschiedlichem Hub betrieben werden.The stroke of the control rods 1 and 2 is within wide limits - these are only dependent on the inner radius of the toothed rim 3 - freely changeable. If the stroke is reduced by the distance between the bearings 6 and 7 is reduced, so only the diameter of the planetary gear 5 must be proportionally increased. If the drive side of the control rods 1 and 2 changed accordingly, so even cylinders with different stroke can be operated.

Auf diese Weise kann im gleichen Gehäuse ein unterschiedlicher Hub eingestellt werden.In this way, a different stroke can be set in the same housing.

Bei umgekehrter Wirkungsweise kann die Vorrichtung beispielsweise als Kolbenpumpe Verwendung finden.In reverse operation, the device can be used for example as a piston pump use.
