Abstract
Description
Die Erfindung betrifft Bauelemente der Pneumatik gemäß Oberbegriff des Anspruches 1.The The invention relates to pneumatic components according to the preamble of the claim 1.
Bei einem ersten bekannten Element dieser Art (PH-Profil EP) bildet der sich axial zwischen dem Dicht- und dem Abstreifteil erstreckende längliche Führungsteil mit diesen nur zum Teil eine massive Einheit aus Polyurethan, die radial außen mit einem zylindrischen Stützring des Führungsteiles verbunden ist, der aus einer Aluminiumlegierung besteht und in den hinterschneidungsfreien Einbauraum eingepresst ist. – Die Fabrikation eines solchen Elementes ist wegen der getrennten Herstellung des metallischen Stützringes und dessen Verbindung mit der Einheit aus Kunststoff relativ aufwendig und schon insoweit nachteilig.at a first known element of this kind (PH profile EP) forms extending axially between the sealing and the stripping part elongated leadership part with these only partially a massive unit of polyurethane, the radially outside with a cylindrical support ring of the leadership part connected, which consists of an aluminum alloy and in the undercreasing-free installation space is pressed. - The fabrication Such an element is due to the separate production of the metallic support ring and its connection to the unit made of plastic relatively expensive and already disadvantageous.
An einem zweiten bekannten Element der eingangs genannten Art mit Dichtteil und Abstreifteil (aneinandergefügt als PH-Profil E8 oder vereinigt als PH-Profil EU) sowie völlig getrenntem flachrechteckig profilierten Führungsteil, das eine eigene Einbaunut im Zylindergehäuse einnimmt, ist nachteilig, dass ein separates Führungsteil und dafür ein zweiter Einbauraum axial zwischen dem Einbauraum für das Dicht- und das Abstreifteil sowie dem Kolben-Hubraum im Zylinder benötigt wird.At a second known element of the type mentioned with sealing part and stripping part (joined together as PH profile E8 or united as PH profile EU) as well as completely separate flat rectangular profiled guide part, which occupies its own installation groove in the cylinder housing, is disadvantageous that a separate guide part and therefor a second installation space axially between the installation space for the sealing and the stripping part and the piston displacement in the cylinder is needed.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Bauelement der eingangs genannten Art ohne die erwähnten Nachteile zu schaffen, welches im Vergleich zu den zwei bekannten Elementen weniger Herstell- und Einbauaufwand erfordert.Of the Invention is therefore based on the object, a component of the above mentioned type without the mentioned Disadvantage to create, which compared to the two known Elements requires less manufacturing and installation costs.
Diese Aufgabe ist erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Diese Lösung stellt eine Kombination der mittelbar vereinigten Dicht- bzw. Abstreifteile mit dem nun einstückigen Führungsteil in der axialen Mitte unter Bildung einer homogenen Einheit aus allen drei Teilen sowie Vermeidung eines zweiten Einbauraumes dar und ist vorteilhaft auch deshalb, weil die Herstellung dieses massiven Pneumatikelementes verhältnismäßig einfach ist.These Task is inventively by the characterizing features of claim 1 solved. This solution represents a combination the indirectly united sealing or Abstreifteile with the now one-piece guide part in the axial center to form a homogeneous unit of all three parts and avoiding a second installation space and is also advantageous because the production of this massive Pneumatic element relatively simple is.
Bei einer idealen Ausführungsform des erfindungsgemäßen Elementes ist das Material des Führungsteiles gemäß Anspruch 2 härter als das Material des Dicht- bzw. Abstreifteiles; z. B. infolge härtender Zusätze zum Kunststoff bei der Ausformung des Führungsteiles.at an ideal embodiment of the element according to the invention is the material of the leadership part according to claim 2 harder as the material of the sealing or stripping part; z. B. due to curing additives for Plastic in the formation of the guide member.
Falls das erfindungsgemäße Element wie das zweite bekannte Element einen einschnappbaren Haltewulst am radial äußeren Umfang des ringförmigen Elementes aufweist, ist gemäß Anspruch 3 vorgesehen, dass der Führungsteil den Haltewulst trägt, dessen Material weicher sein soll als das Material des Führungsteiles, d.h. so weich wie das Material des Dicht- bzw. Abstreifteiles; und welcher eine Halteschulter aufweist, die sich am Einstich axial abstützt.If the element of the invention as the second known element a snap-in retaining bead at the radially outer periphery of the annular Element has, is according to claim 3 provided that the guide part wearing the retaining bead, whose material should be softer than the material of the guide part, i.e. as soft as the material of the sealing or stripping part; and which has a retaining shoulder, the axial at the puncture supported.
Im Folgenden ist die Erfindung anhand der beigefügten Zeichnung eines Ausführungsbeispiels des beanspruchten Pneumatikelementes in Verbindung mit einem Pneumatikzylinder im Einzelnen erläutert.in the Below is the invention with reference to the accompanying drawings of an embodiment of the claimed Pneumatikelementes in conjunction with a pneumatic cylinder explained in detail.
Die einzige Figur der Zeichnung zeigt die obere Hälfte der Profile des Einbauraumes des Zylinders bzw. des eingebauten Elementes im entspannten Zustand.The single figure of the drawing shows the upper half of the profiles of the installation space of the cylinder or the built-in element in the relaxed state.
