Arbeitszylinder für pneumatische oder hydraulischeWorking cylinder for pneumatic or hydraulic
ArbeitsmedienWorking media
Die Erfindung betrifft einen Arbeitszylinder für pneumatische oder hydraulische Arbeitsmedien, der quer zu einer Mittelachse symmetrisch ausgebildet ist und in dem ein einseitig oder doppelseitig beaufschlagbarer und ebenfalls symmetrisch zu der Mittelachse ausgebildeter Kolben vorgesehen und geführt ist.The invention relates to a working cylinder for pneumatic or hydraulic working media, which is transverse to a central axis is designed symmetrically and in which a one-sided or double-sided actable and also symmetrical to the central axis trained piston is provided and guided.
Es ist bekannt, bei derartigen Zylindern ZyIinderinnenräume mit kreisförmigem Querschnitt und dementsprechend kreisförmig ausgebildete Kolben vorzusehen. Diese Anordnung erfordert vielfach eine Verdrehsicherung für den Kolben.It is known to have cylinder interiors in such cylinders with a circular cross-section and accordingly circular to provide trained pistons. This arrangement often requires an anti-twist device for the piston.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung der eingangs genannten Art zu schaffen, bei der eine zusätzliche Verdrehsicherung nicht erforderlich ist.The invention is based on the object of an arrangement of the initially to create the type mentioned, in which an additional anti-rotation device is not required.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Innenquerschnitt des Zylinders bzw. der Außenquerschnitt des Kolbens so ausgebildet sind, daß zwei um 45° versetzte Durchmesser des Zylinders bzw. Kolbens von unterschiedlicher Länge sind.This object is achieved according to the invention in that the inner cross-section of the cylinder or the outer cross-section of the piston are designed so that two diameters of the Cylinders or pistons are of different lengths.
Die Erfindung geht somit von der Erkenntnis aus, daß die der Erfindung zugrundeliegende Aufgabe bereits durch die Formgestaltung von Kolben bzw. Zylinder ohne zusätzliche "Verdrehsicherung gelöst wird, wenn der Innenquerschnitt des Zylinders bzw. der Außenquerschnitt des Kolbens unrund, also nicht kreisförmig und somit beispielsweise oval, rechteckig usw. ausgebildet ist.The invention is thus based on the knowledge that the object on which the invention is based is already based on the design is released from the piston or cylinder without additional "anti-rotation device" if the internal cross-section of the cylinder or the outer cross-section of the piston is non-circular, that is, not circular and thus, for example, oval, rectangular, etc. is.
In zweckmäßiger Weiterbildung der Erfindung kann vorgesehen sein, daß der Innenquerschnitt des Zylinders bzw. der Außenquerschnitt des Kolbens ein 3. echt eckquer schnitt ist. Diese Maßnahme bietet zum einen den Vorteil, daß die Flächen einfach zu bearbeiten sind, da es sich um ebene Flächen handelt, und zum anderen kann damit die gesamte Anordnung in einer Richtung flacher als eine Anordnung mit kreisförmigen Innen- bzw. Außenquerschnitten gestaltet werden. Die Anordnung beansprucht somit in einer Rich-In an expedient development of the invention it can be provided that the inner cross-section of the cylinder or the outer cross-section of the piston is a third real corner cross-section. This measure offers the advantage, on the one hand, that the surfaces are easy to machine, since they are flat surfaces, and, on the other hand, the entire arrangement can be made flatter in one direction than an arrangement with circular inner or outer cross-sections. The arrangement thus claims in one direction

- 3 tung weniger Raum als bekannte Anordnungen.- 3 less space than known arrangements.
Weiterhin kann vorgesehen sein, daß die Ecken des Zylinders bzw. die Jacken des Kolbens abgerundet ausgebildet sind.Furthermore, it can be provided that the corners of the cylinder or the jackets of the piston are rounded.
In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung schematisch dargestellt. Es zeigen:In the drawing, an embodiment of the subject matter of the invention is shown schematically. Show it:
Fig. 1 einen Querschnitt durch einen'Teilabschnitt eines Kolbens, in dem ein an einer Kolbenstange angebrachter Zylinder hin und her bewegbar geführt ist, und1 shows a cross section through a partial section of a piston, in which a cylinder attached to a piston rod is guided so that it can move back and forth, and
Fig. 2 einen Schnitt längs der Linie H-H in Pig. 1.Fig. 2 is a section along the line H-H in Pig. 1.
In einem Zylinder 1 ist eine Kolbenstange 2 entsprechend der Richtung des Pfeiles A hin und her bewegbar angeordnet. Die Kolbenstange 2 weist an einem Ende einen Teil 3 auf, der gegenüber dem Teil 2.einen kleineren Querschnitt aufweist, so daß eine Schulter 4 gebildet ist, gegen die ein Kolben 5 anliegt, der auf dem der Schulter 4- gegenüberliegenden ü-nde mittels einer auf ein Gewindeteil 6 der Kolbenstange 2 aufgeschraubten Mutter 7 befestigt ist. Sem zwischen dem Zylinder 1 und der Kolbenstange 2 gebildeten Raum 8 ist ein Fluid, beispielsweise Druckluft, über eine (nicht dargestellte) Einrichtung zuführbar, derart, daß dadurch die Kolbenfläche 9 des Kolbens 5 beaufschlagbar und somit eine Bewegung des KolbensIn a cylinder 1 is a piston rod 2 according to the Arranged movable to and fro in the direction of arrow A. The piston rod 2 has at one end a part 3 which has a smaller cross-section compared to part 2, so that a shoulder 4 is formed against which a piston 5 on the edge on the opposite side of the shoulder 4 is fastened by means of a nut 7 screwed onto a threaded part 6 of the piston rod 2. Sem between the cylinder 1 and the piston rod 2 formed space 8 is a fluid, for example compressed air, via a device (not shown) can be fed in such that the piston surface 9 of the piston 5 can thereby be acted upon and thus a movement of the piston

entsprechend der Zeichnung nach rechts möglich ist. Das in dem Raum 1o befindliche Fluid kann durch eine Öffnung 11 abgeleitet werden. Die oben beschriebene Gestaltung des Kolbens, des Zylinders und der Befestigung des Kolbens an der Kolbenstange sind nur zur schematischen Erläuterung des grossen Zusammenhangs bestimmt, mit der Erfindung haben sie nichts zu tun.according to the drawing to the right is possible. The fluid located in the space 1o can be discharged through an opening 11 will. The above-described design of the piston, the cylinder and the attachment of the piston to the piston rod are only for a schematic explanation of the broader context definitely they have nothing to do with the invention.
Wie aus Figo 2 ersichtlich, weist der Zylinder 1 quer zur Hubrichtung A gesehen einen rechteckigen Innenquerschnitt mit abgerundeten Innenecken 12 auf. Der Kolben 5 weist dementsprechend einen rechteckigen Außenquerschnitt mit abgerundeten Außenecken 13 auf. Die üblicherweise vorgesehenen Kolbenringe, Dichtungen und dgl. sind nicht dargestellt. In S1Ig. 2 sind zwei Durchmesser des Zylinders eingezeichnet, die beide durch die Mittelachse der Anordnung gehen, aber um einen Winkel um 45 versetzt sind. Die beiden Durchmesser sind mit 14 bzw. I5 bezeichnet. Wie ersichtlich, sind die Durchmesser 14 und 15 von unterschiedlicher Länge.As can be seen from FIG. 2, the cylinder 1 has a rectangular inner cross-section with rounded inner corners 12, seen transversely to the stroke direction A. The piston 5 accordingly has a rectangular outer cross section with rounded outer corners 13. The piston rings, seals and the like that are usually provided are not shown. In S 1 Ig. 2 two diameters of the cylinder are shown, both of which pass through the central axis of the arrangement, but are offset by an angle of 45. The two diameters are denoted by 14 and 15, respectively. As can be seen, the diameters 14 and 15 are of different lengths.
.es bedarf keiner näheren Erläuterung, daß der Kolben 5 ohne weitere Maßnahme verdrehsicher in dem Zylinder 1 angebracht ist. Die Breite B der Gesamtanordnung ist geringer als bei einer entsprechenden Anordnung mit kreisförmiger Kolbenfläche..es needs no further explanation that the piston 5 without further measure is attached in the cylinder 1 so that it cannot rotate. The width B of the overall arrangement is less than that of a corresponding arrangement with a circular piston surface.
