Description
Die Erfindung bezieht sich auf eine Druckluftkupplung für das Trennen des Steckers durch Abziehen mit federbelastetem Ventil und einer axial verschiebbaren Verriegelungshülse mit nur einem Kugelgesperre sowie angeschlossenem zapfenförmigen Druckausgleichsteil, geführt in einem Kupplungskörper für Festeinbau, der mit einer Zusatzrastung und nach außen ohne Unterbrechungen wirkender ringförmigen Dichtung ausgeführt ist.The The invention relates to a pneumatic coupling for separation of the plug by pulling with spring loaded valve and a axially displaceable locking sleeve with only one ball locking mechanism as well as connected cone-shaped Pressure equalizing part, guided in a coupling body for permanent installation, the one with an additional catch and the outside without interruptions acting annular Seal executed is.
Druckluftkupplungen
für das
Trennen des Steckers durch Abziehen mit federbelasteten Ventil und
einer verschiebbaren Verriegelungshülse mit einem Kugelgesperre
sowie angeschlossenem zapfenförmigen
Druckausgleichsteil sind bekannt (
Diese Ausführung gewährleistet einen exakten Ausgleich der an der Verriegelungshülse wirkenden Axialkräfte, sichert jedoch bei Zugkräften am Kupplungsstecker nicht umfassend die Verbindung von Druckluftkupplung und Kupplungsstecker im Arbeitsprozess, wodurch eine zusätzliche im Kupplungskörper, die Funktion beim Stecken nachteilig beeinflussende Druckfeder angeordnet ist. Hinzu kommt, daß die Ausführung des Druckausgleichsteiles und der Verriegelungshülse sehr aufwendig hinsichtlich Fertigung und Abmessungen sind.These execution guaranteed an exact balance acting on the locking sleeve axial forces, but secures with tensile forces on the coupling plug not comprising the connection of compressed air coupling and coupling plug in the working process, creating an additional in the coupling body, the function when plugging adversely affecting compression spring arranged is. In addition, the execution the pressure compensation part and the locking sleeve very expensive in terms Manufacturing and dimensions are.
Auch
sind Hydraulikkupplungen für
das Trennen des Steckers durch Abziehen bekannt (
Hydraulikkupplungen unterscheiden sich aber von Druckluftkupplungen grundsätzlich durch folgende Merkmale:
- – Hydraulikkupplungen besitzen generell sowohl in der Kupplung als auch im Stecker federbelastete, gegenüber der Umwelt dicht sperrende Ventile, da das Fluid Hydrauliköl nicht an die Umwelt gelangen darf. Bei Druckluftkupplungen besitzen die Stecker grundsätzlich keine gegenüber der Umwelt dicht sperrenden Ventile, da die Druckluft an die Umwelt entweichen darf.
- – Hydraulikkupplungen werden auch für Drücke über 400 bar eingesetzt und erfordern daher einen hohen Konstruktions- und Fertigungsaufwand. Druckluftkupplungen werden in der Praxis für wesentlich geringere Drücke bis etwa 16 bar eingesetzt und sind demzufolge weniger aufwendig in Konstruktion und Fertigung.
- - Hydraulic couplings generally have both in the coupling and in the plug spring-loaded, against the environment tight blocking valves, since the fluid hydraulic oil must not reach the environment. In the case of compressed air couplings, the plugs generally have no valves that are tightly sealed against the environment, since the compressed air may escape to the environment.
- - Hydraulic couplings are also used for pressures over 400 bar and therefore require a high design and manufacturing costs. Compressed air couplings are used in practice for much lower pressures up to about 16 bar and are therefore less expensive in construction and manufacturing.
Die vorgenannten Unterschiede ergeben für die aufgeführte Hydraulikkuplung nachfolgende für Druckluftkupplungen völlig ungeeigneten Merkmale.The aforementioned differences result for the listed hydraulic coupling subsequent for compressed air couplings completely unsuitable characteristics.
Die Hydraulikkupplung verfügt über zwei Kugelgesperre, außer den Ventilfedern zwei zusätzlich im Ventilkörper angeordnete Druckfedern sowie insgesamt 5 miteinander in Verbindung stehende 5 Hülsenteile und ist damit für einem Vergleich mit einer Druckluftkupplung nicht relevant.The Hydraulic coupling has two Ball lock, except the valve springs two in addition valve body arranged compression springs and a total of 5 in conjunction standing 5 sleeve parts and is for not relevant to a comparison with a compressed air coupling.
Weiterhin
ist eine Druckluftkupplung bekannt (
Auch diese Kupplung verfügt außer der Ventilfeder über eine zusätzliche Druckfeder, eine sehr Verschleiß intensive Dichtung nach außen und besitzt demzufolge keine Gemeinsamkeiten mit einer Druckluftkupplung für das Trennen des Steckers von der Kupplung durch Ziehen.Also this clutch has except the valve spring over an additional Compression spring, a very wear intensive Seal to the outside and therefore has no similarities with a compressed air coupling for the Disconnect the connector from the coupling by pulling.
Der Erfindung liegt die Aufgabe zu Grunde, eine Druckluftkupplungen für das Trennen des Steckers durch Abziehen mit federbelastetem Ventil und einer axial verschiebbaren Verriegelungshülse mit nur einem Kugelgesperre sowie einem angeschlossenen Druckausgleichsteil geführt in nur einem Kupplungskörper für Festeinbau ohne zusätzlicher Druckfeder zu schaffen, der mit einer Zusatzrastung und nach außen wirkender Verschleiß armer Dichtung ausgerüstet ist.Of the Invention is based on the object, a compressed air couplings for the Disconnect the connector by pulling it off with spring loaded valve and one axially displaceable locking sleeve with only one ball locking mechanism as well as a connected pressure equalizing part guided in only a coupling body for permanent installation without additional compression spring to create, with an additional catch and outward acting Wear poorer Equipped with gasket is.
Erfindungsgemäß geschieht das dadurch, daß in der Druckluftkupplung für das Trennen des Steckers durch Abziehen mit federbelastetem Ventil, einer axial verschiebaren Verriegelungshülse und angeschlossenem Druckausgleichsteil sowie nur einem Kugelgesperre mit einer im einteiligem Kupplungskörper angeordneten einseitig nach außen offenen ringförmigen Kugelaufnahme, wobei der Kupplungskörper am Führungsdurchmesser unmittelbar nach der Schräge der nach außen offenen ringförmigen Kugelaufnahme eine im Durchmesser geringfügig vergrößerte dem Durchmesser der Rastkugel entsprechenden Breite und beidseitig geschlossene Rastrille aufweist.According to the invention happens this by the fact that in the compressed air coupling for disconnecting the plug by pulling it off with a spring-loaded valve, one axially lockable locking sleeve and connected pressure compensation part and only one Kugelgesperre arranged with a one-piece coupling body one-sided to the outside open annular Ball seat, wherein the coupling body on the guide diameter directly after the slope the outside open annular ball socket a slightly larger in diameter Diameter of the detent ball corresponding width and closed on both sides latching groove having.
Eine Weiterbildung geschieht dadurch, dass der Kupplungskörper eine auf der Verriegelungshülse durchgängig ohne Unterbrechungen gleitende ringförmige Dichtung zur Trennung des Druckraumes von der Außenluft aufweist, der Kupplungskörper zur Befestigung in einer Aufnahme ein Außengewinde und einen Zentrierzapfen besitzt und die axial verschiebbare Verriegelungshülse mit einem im Durchmesser mehrfach gestuften, im Mittelteil mit der Außenluftverbundenen zapfenfötmigen Druckausgleichsteil verbunden ist, das außer zwei rinförmigen Dichtungen keine weiteren Einbauteile beinhaltet.A Further development occurs in that the coupling body on the locking sleeve continuously non-stop sliding annular seal for separation the pressure chamber from the outside air has, the coupling body for attachment in a receptacle an external thread and a centering pin has and the axially displaceable locking sleeve with a multi-stepped in diameter, connected in the middle part with the outside air zapfenfötmigen Pressure equalization part is connected, which except two Rin-shaped seals No further built-in parts included.
