Abstract

The device converts axial motion to radial motion or vice versa. Two cogs (3,4) that are eccentrically and rigidly mounted on two cranked camshafts (1,2) drive the two cogs (5,6) in the same direction of rotation. The cogs are of the same radius as the radius of the cranked section of camshaft. This radius is equal to a quarter of the stroke of the engine's pistons (not shown). Thus, the cogs rotate about a radius equal to one half of the stroke. In the process, the central connecting rod (8), that is located in the central bearing (7), also rotates as it is rigidly attached to the axes of the two eccentric cogs. As the cranked camshafts rotate, they produce an axial movement of the connecting rods (9,10) that drives the engine's pistons up and down.

Description

Die Erfindung betrifft einen pleuelstangenlosen Antriebs­ mechanismus, insbesondere für einen Verbrennungsmotor, mit zwei Kurbeln, auf denen jeweils starr ein mit der ent­ sprechenden Kurbel zusammen drehbares Zahnrad mit einem Radius des Anfangkreisumfangs montiert ist, der gleich einem Viertel eines Kolbenhubes des Verbrennungsmotors ist, auch mit einem Paar unverschiebbarer, im Innern des An­ triebsmechanismus verankerter, um ihre Achsen drehbarer Zahnräder mit einem Radius des Anfangkreisumfangs, der gleich der Hälfte des Kolbenhubes ist, die mit den auf den Kurbeln montierten Zahnrädern wechselwirkend in Eingriff bringbar sind.The invention relates to a connecting rodless drive mechanism, in particular for an internal combustion engine, with two cranks, each rigidly with the ent speaking crank together rotatable gear with a Radius of the initial circumference is mounted, the same is a quarter of a piston stroke of the internal combustion engine, even with a pair of immovable, inside the An drive mechanism anchored to rotate about its axes Gears with a radius of the initial circumference, the is equal to half of the piston stroke, which with the on the Crank-mounted gears interact with each other are feasible.

Pleuelstangenlose Antriebsmechanismen dieser Art können in vielfältiger Hinsicht im Maschinenbaubereich, insbesondere bei Verbrennungsmotoren und Kompressoren und in allen Maschinenkonstruktionen Anwendung finden, bei denen eine geradlinige Bewegung in eine Drehbewegung und umgekehrt um­ gewandelt werden soll.Connecting rodless drive mechanisms of this type can be used in diverse respects in the mechanical engineering field, in particular in internal combustion engines and compressors and in all Machine designs are used where one rectilinear movement into a rotary movement and vice versa to be changed.

Der Erfindung liegt daher die Aufgabe zugrunde, einen pleuelstangenlosen Antriebsmechanismus der eingangs erwähn­ ten kompakten Bauausführung und beträchtlicher technischer Langlebigkeit zur Verfügung zu stellen.The invention is therefore based on the object connecting rodless drive mechanism mentioned at the beginning  th compact design and considerable technical To provide longevity.

Diese Aufgabe wird erfindungsgemäß gelöst durch mindestens eine unverschiebbare, ein Gelenk derart halternde Stütze, daß die jeweils mit einer der Kurbeln zusammen drehbaren Zahnräder scharnierartig durch Arme des Gelenks miteinander verbunden und die Zahnräder in eine Gegenphase verlagerbar sind.This object is achieved by at least an immovable support that holds a joint like this, that the rotatable together with one of the cranks Gears hinged together by arms of the joint connected and the gears can be shifted into an opposite phase are.

Der erfindungsgemäße pleuelstangenlose Antriebsmechanismus eignet sich durch die mögliche beträchtliche Verringerung üblicher Ausmaße von Antriebsmechanismen insbesondere für den Einsatz in Verbindung mit Verbrennungsmotoren und Kom­ pressoren, zumal seine technische Lebensdauer im Vergleich zu herkömmlichen Antriebsmechanismen deutlich länger ist.The connecting rodless drive mechanism according to the invention is suitable due to the possible considerable reduction usual dimensions of drive mechanisms especially for use in connection with internal combustion engines and com pressors, especially since its technical life in comparison to conventional drive mechanisms is significantly longer.

Eine bevorzugte Ausführungsform des erfindungsgemäßen pleuelstangenlosen Antriebsmechanismus wird nun anhand der einzigen Figur der Zeichnung erläutert. Wie aus dieser Figur hervorgeht, weist der pleuelstangenlose Antriebs­ mechanismus zwei Kurbeln 1, 2 auf, auf denen starr mit letzteren drehbare Zahnräder 3 bzw. 4 befestigt sind, die einen Radius des Anfangkreisumfangs aufweisen, der gleich einem Viertel des Kolbenhubs (in der Zeichnung nicht dar­ gestellt) ist. Weiterhin besitzt der pleuelstangenlose An­ triebsmechanismus ein Paar unverschiebbare Zahnräder 5 und 6, die innen verankert sind und einen Radius des Anfang­ kreisumfangs aufweisen, der gleich einem halben Kolbenhub ist, wobei die Zahnräder 3 und 4 unter Berücksichtigung eines möglichen wechselnden Eingriffs mit den unverschieb­ baren Zahnrädern 5 bzw. 6 auf den Kurbeln 1 bzw. 2 montiert sind. Der Antriebsmechanismus ist ferner mit einer Stütze 7 ausgerüstet, die mit einem zusätzlichen Gelenk 8 versehen ist, das die Zahnräder 3 und 4 scharnierartig verbindet und eine Verlagerung letzterer in einer Gegenphase ermöglicht. A preferred embodiment of the connecting rodless drive mechanism according to the invention will now be explained with reference to the single figure of the drawing. As is apparent from this figure, the connecting rodless drive mechanism has two cranks 1 , 2 , on which rigidly rotatable gears 3 and 4 are fastened with the latter, which have a radius of the initial circular circumference, which is equal to a quarter of the piston stroke (not in the drawing represents) is. Furthermore, the connecting rodless drive mechanism has a pair of immovable gears 5 and 6 , which are anchored inside and have a radius of the beginning of the circumference, which is equal to half a piston stroke, the gears 3 and 4 taking into account a possible alternating engagement with the unmovable gears 5 and 6 are mounted on cranks 1 and 2 , respectively. The drive mechanism is also equipped with a support 7 which is provided with an additional joint 8 which connects the gears 3 and 4 in a hinge-like manner and enables the latter to be displaced in an opposite phase.

Der Antriebsmechanismus arbeitet folgendermaßen:
Um die unverschiebbaren Zahnräder 5 und 6, die sich bezogen auf ihre Achse im Gegenuhrzeigersinn drehen, bewegen sich die auf den Kurbeln 1 und 2 starr montierten Zahnräder 3 bzw. 4. Dabei dreht sich das zusätzliche Gelenk 8, das von der stationären Stütze 7 gehaltert ist, im Uhrzeigersinn. Auf den Armen des Gelenks 8 sind die auf den Kurbeln 1 und 2 starr montierten Zahnräder 3 bzw. 4 befestigt. Die Achsen der Kurbeln 1, 2 vollführen eine geradlinige Bewegung mit Stangen 9, 10 und dem in der Figur nicht dargestellten Kolben.The drive mechanism works as follows:
The rigidly mounted gears 3 and 4 on the cranks 1 and 2 move around the non-displaceable gears 5 and 6 , which rotate counterclockwise with respect to their axis. The additional joint 8 , which is held by the stationary support 7, rotates clockwise. On the arms of the joint 8 , the gears 3 and 4 rigidly mounted on the cranks 1 and 2 are fastened. The axes of the cranks 1 , 2 perform a linear movement with rods 9 , 10 and the piston, not shown in the figure.
