Description

1Vlaschinenelement zur Verbindung zweier gegenüberliegender Kolben zum Antrieb durch eine Kurbel. Zur Verbindung gegenüberliegender" Kolben, die von einer Kurbel aus angetrieben werden, dient die Kurbelschleife oder das Kleinsche Maschinenelement. Die Kurbelschleife hat den Nachteil eines sehr schlechten Wirkungsgrades; ihre Anwendung ist daher auf kleine Ausführungen beschränkt. Außerdem sind bei ihr ebenso wie beim Kleinschen Maschinenelement Schrauben- oder Keilbefestigungen zur Verbindung des Kolbens mit dem Verbindungsteil erforderlich. Endlich ergeben beide Maschinenelemente eine ziemlich große Maschinenlänge.1 machine element for connecting two opposing pistons to be driven by a crank. To connect opposing "pistons, which are from are driven from a crank, the crank loop or the Kleinsche is used Machine element. The slider crank has the disadvantage of a very poor efficiency; their use is therefore limited to small versions. Also are with her as well as screw or wedge fastenings for the Klein machine element Connection of the piston with the connecting part required. Finally both surrender Machine elements a fairly large machine length.

Beim Gegenstand der Erfindung werden diese Nachteile vermieden. Die beiden Kolben werden hier durch bogenförmige Halbstücke verbunden, deren Enden halbzylinderförmig gestaltet sind und die mit nach innen ragenden Ansätzen entsprechende Eindrehungen des Kolbens und ,des Kolbenzapfens übergreifen. Zweckmäßig werden sie durch darübergeschobene Ringe zusammengehalten.In the subject matter of the invention, these disadvantages are avoided. the Both pistons are connected here by arched half-pieces, the ends of which are semicylindrical are designed and the corresponding grooves with inwardly protruding approaches of the piston and the piston pin overlap. They are expedient by being pushed over them Rings held together.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung, und zwar zeigen Fig. x und 2 verschiedene Schnitte. Die bogenförmigen Verbindungshalbstücke sind mit a bezeichnet; die halbzylinderförmigen Enden b sind mit nach innen ragenden ringförmigen Ansätzen c versehen, die über entsprechende Ansätze d des Kolbenzapfens e und der Kolben f hinweggreifen. Über die Enden der Verbindungshalbstücke sind Ringe g geschoben; hierdurch werden die beiden Verbindungshalbstücke zusammengehalten. Ansätze da verhindern, daß die Ringe g nach innen über die Verbindungshalbstücke hinweggleiten können. Zweckmäßig werden die Ringe g durch Schrauben i mit den Verbindungsstücken verbunden und dadurch gegen Abgleiten nach außen sowie gegen -Verdrehung gesichert. Der Kolbenzapfen e wird zweckmäßig in einem Arbeitsgang mit dem Kolben f überdreht, so daß sich die dem Kurbelzapfen zugewendeten Flächen der ringförmigen Ansätze c der Verbindungsstücke gegen die entsprechenden Ansätze d des Kolbens und der Kolbenzapfen legen. Die Ringe g dienen gleichzeitig als Geradführung in der Gleitbahn i, so daß dem Kolben nur die Aufgabe des Abdichtens und der Arbeitsübertragung zukommt.The drawing shows an embodiment of the invention, namely Fig. x and 2 show different sections. The arched connecting halves are denoted by a; the semi-cylindrical ends b are with inwardly protruding annular lugs c provided, which have corresponding lugs d of the piston pin e and the piston f reach away. Over the ends of the connecting halves are Rings g pushed; this holds the two connecting halves together. Approaches da prevent the rings g inward over the connecting halves can slide away. The rings g are expediently secured to the connecting pieces by screws i connected and thus secured against sliding outwards and against twisting. The piston pin e is expediently turned over in one operation with the piston f, so that the surfaces of the annular lugs facing the crank pin c of the connecting pieces against the corresponding lugs d of the piston and the piston pin place. The rings g also serve as a straight line guide in the slideway i, so that the piston only has the task of sealing and transferring work.

Außer den erwähnten Vorteilen sind dem neuen Maschinenelement noch eine Reihe anderer eigen. Es ist für Massenfabrikation sehr geeignet. Der Zusämmenbau gestaltet sich äußerst einfach; ein Nachziehen von Befestigungs- öder Stellvorrichtungen während des Betriebes ist nicht erforderlich.In addition to the advantages mentioned, the new machine element still has a number of others own. It is very suitable for mass production. The assembly turns out to be extremely simple; tightening of fastening or adjusting devices during operation is not required.
