Description

Die Erfindung bezieht sich auf kugelgelenkartige Rohrkupplungen, bei denen die kugelförmigen Enden von zwei miteinander verbundenen Rohrstücken durch eine Feder auseinander- und in hohlkugelförmige Sitze eines Gehäuses gedrückt werden. Bei den bekannten Rohrkupplungen dieser Art sind die aufeinanderliegenden Lagerflächen an den Kugelflächen verhältnismäßig klein, und bei höheren Drücken in der Rohrleitung treten leicht Undichtigkeiten auf, insbesondere nach größerer Abnutzung oder wenn die Rohrleitung in Längsrichtung zusammengedrückt wird. Die Erfindung bezieht sich insbesondere auf Rohrkupplungen für Schmierpressen, die über eine gute, dauernde Abdichtung verfügen müssen. Gemäß der Erfindung wirkt die im Innern des Kupplungsgehäuses angeordnete Feder auf im Querschnitt keilförmige Ringe ein, welche in einen Stulp-Dichtungsring eintreten, dessen Schenkel den Kehlflächen des Ringes angepaßt sind, wobei der eine Schenkel gegen die innenliegende Kugelfläche der Rohrstücke und der andere Schenkel gegen die innere Wandung des Gehäuses gedrückt wird.The invention relates to ball joint-type pipe couplings in which the spherical ends of two pipe pieces connected to one another by a spring apart and are pressed into hollow spherical seats of a housing. Both known pipe couplings of this type are the superposed bearing surfaces on the Spherical surfaces are relatively small and occur in the pipeline at higher pressures easily leaks, especially after major wear and tear or when the pipeline is compressed in the longitudinal direction. The invention particularly relates to on pipe couplings for grease guns, which must have a good, permanent seal. According to the invention the spring arranged in the interior of the clutch housing acts on a wedge-shaped cross-section Rings, which enter a faceplate sealing ring, the legs of which the Throat surfaces of the ring are adapted, with one leg against the inner one Spherical surface of the pipe pieces and the other leg against the inner wall of the housing is pressed.

Die Zeichnung stellt im Längsschnitt ein Ausführungsbeispiel der neuen Rohrkupplung in Verbindung mit einer Schmierpresse dar.The drawing shows an embodiment of the new pipe coupling in longitudinal section in connection with a grease gun.

Die Schmierpresse 1 besteht aus dem Schmiermittelzylinder 2, in welchem der Niederdruckkolben 3 angeordnet ist, und einem Förderzylinder 11, in welchem der Hochdruckkolben 12 gleitbar gelagert ist. Der durch eine Feder 7 nach einwärts gedrückte Kolben 3 kann durch eine Feder 8 in seiner zurückgezogenen Lage festgehalten werden. Der Schmiermittelzylinder 2 ist durch eine Öffnung 9 mit dem Zylinder 11 verbunden. Der Hochdruckkolben 12 wird durch einen Handgriff 13 betätigt, der gelenkig an den Kolben 12 und den Zylinder 11 angeschlossen ist.The lubricating press 1 consists of the lubricant cylinder 2, in which the low-pressure piston 3 is arranged, and a delivery cylinder 11, in which the high pressure piston 12 is slidably mounted. The pushed inward by a spring 7 Piston 3 can be held in its retracted position by a spring 8. The lubricant cylinder 2 is connected to the cylinder 11 through an opening 9. The high pressure piston 12 is operated by a handle 13 which is articulated to the Piston 12 and the cylinder 11 is connected.

Ein Rohrstück 22 ist bei 23 in_ den Zylinder 11 hineingeschraubt und hat einen kugelförmigen Kopf 24, durch welchen sich die Bohrung 26 hindurcherstreckt. Ein zweites ähnliches Rohrstück 27 ist kugelgelenkartig mit dem ersten Rohrstück 22 verbunden.A pipe section 22 is at 23 in_ the cylinder 11 screwed into it and has a spherical head 24 through which the Bore 26 extends therethrough. A second similar piece of pipe 27 is like a ball joint connected to the first pipe section 22.

Die dazu benutzte Kupplung 28 besteht aus den beiden Hülsenkappen 29, 31, die an den einander zugekehrten offenen Enden mit aufeinanderpassenden Innen- und Außenge-. winden 32 versehen sind. Jede dieser Hülsen 29, 31 hat einen Boden, und in der Mitte des Bodens befindet sich eine Öffnung 33 bzw. 34 mit hohlkugelförmiger Umgrenzungswand. Diese Öffnungen bilden den Sitz für die Kugelenden der Rohrstücke 22, 27, welchThe coupling 28 used for this purpose consists of the two sleeve caps 29, 31, which are attached to the facing open ends with matching inner and outer surfaces. winds 32 are provided. Each of these sleeves 29, 31 has a bottom, and in the middle the bottom is an opening 33 or 34 with a hollow spherical boundary wall. These openings form the seat for the ball ends of the pipe sections 22, 27, which

letztere vor Zusammenschrauben der Hülsenkappen 29, 31 in die einzelnen Hülsen eingesetzt werden. Die Kugelenden werden durch nachgiebige Dichtungsringe 36 auf ihren Sitz gedrückt. Diese Dichtungsringe 36 bestehen aus zwei aneinanderhängenden ringförmigen Flanschen 37, 38* von denen der eine gegen das innere Kugelende und der andere gegen die Innenwandung der Hülse 29 bzw. 31 gedrückt wird. Der Druck der Dichtungsringe gegen die Kugelköpfe erfolgt durch starre Ringe 39, die im Querschnitt keilförmig sind und deren keilförmiger Endteil 42 in den Ringraum zwischen die Schenkel 37 und 38 der Stulp-Dichtungsringe 36 eintritt. Jener Teil des Ringes 39, der unmittelbar dem Kugelkopf gegenüberliegt, ist mit Nuten 43 versehen, um dem unter Druck befindlichen Schmiermittel den Zutritt zum Schen- the latter inserted into the individual sleeves before the sleeve caps 29, 31 are screwed together will. The ball ends are seated by flexible sealing rings 36 pressed. These sealing rings 36 consist of two adjacent annular Flanges 37, 38 * one of which against the inner ball end and the other pressed against the inner wall of the sleeve 29 and 31, respectively will. The pressure of the sealing rings against the ball heads takes place through rigid rings 39 which are wedge-shaped in cross-section and the wedge-shaped end portion 42 thereof enters the annular space between the legs 37 and 38 of the faceplate sealing rings 36. That part of the ring 39 which is directly opposite the ball head is grooved 43 to prevent the pressurized lubricant from entering the

Die beiden Ringe 39 werden durch eine gemeinsame Feder 44 nach entgegengesetzten Richtungen gedrückt.ao kel 38 to allow this leg is also pressed against the ball head by the pressure of the lubricant. the two rings 39 are moved by a common spring 44 in opposite directions pressed.

Um eine derartig hergestellte nachgiebige Rohrverbindung mit einem zu schmierenden Lager zu verbinden, wird an dem L'ager 47 ein Stutzen 46 angesetzt, der an seinem Ende 48 konisch ist. Das Ende 48 dringt in den zweiflanschigen Dichtungsring 49 hinein, der in der Kupplung 51 liegt. Ein unter Federkraft stehender Ring 52 im Innern der Kupplung ragt in den Ringraum des Stulp-Dichtungsringes 49 hinein und gewährleistet eine gute Verbindung der Schmierleitung mit dem Lager 47.In order to lubricate a flexible pipe connection produced in this way with a To connect bearings, a nozzle 46 is attached to the bearing 47, which at its end 48 is conical. The end 48 penetrates into the double-flange sealing ring 49, the is in the coupling 51. One under spring force Standing ring 52 inside the coupling protrudes into the annular space of the faceplate sealing ring 49 and ensures a good connection between the lubrication line and the Camp 47.

Die Kupplung 51 wird durch eine Muffe 54 mit dem Stutzen 46 verbunden, indem in der Muffe angeordnete Kugeln 56 in eine Ringnut des Stutzens eintreten-The coupling 51 is connected to the socket 46 by a sleeve 54, in that in the Sleeve arranged balls 56 enter an annular groove of the connecting piece -
