Description
aus den beiden Flanschteilen bestehende Ganze mit dem Flansch eines anderen Schlauchabschnittes durch nicht dargestellte Bolzen zu verbinden.The whole consisting of the two flange parts with the flange of another hose section to connect by bolts not shown.
Die Oberflächen der Flanschteile 7 und 8, welche mit dem Schlauch 1 oder seiner Bewehrung in Beruhrung treten, sind so behandelt, daß der darin enthaltene elastomere Stoff gut anklebt. Sie sind beispielsweise vermessingt. Es können sich dazwischen besondere klebende Gummistoffe befinden.The surfaces of the flange parts 7 and 8, which are in contact with the hose 1 or its reinforcement are treated in such a way that the elastomeric material they contain adheres well. You are for example brass-plated. There may be special adhesive rubber materials in between.
Um die zwischen den Flanschteilen 7 und 8 eingespannten Kabel besser gegen ein eventuelles Eintreten von Feuchtigkeit durch die Bolzenlöcher 7 B und 8 B zu schützen, kann jedes der Löcher des einen der beiden Flanschteile vorzugsweise jedes der Löcher des Flanschteiles7 mit einem starren Rohrstück 7C versehen sein, welches wenigstens teilweise in die Löeher des anderen Flanschteiles hineinragt.To better protect the clamped between the flange 7 and 8 wire against a possible entry of moisture through the bolt holes 7 B and 8 B, each of the holes can be of one of the two flange portions preferably each of the holes of the Flanschteiles7 with a rigid piece of pipe 7C be provided , which protrudes at least partially into the holes of the other flange part.
Der äußere Flanschteils hat auf seiner äußeren Stirnfläche 8 C eine ringförmige Ausnehmung 8 D, in welcher die elastomere Schicht 4 einen axialen Ansatz 9 bildet, der beim Zusammenfügen der Flansche zweier aufeinanderfolgender Schlauchstücke als Dichtung dient.The outer flange part has an annular recess 8 D on its outer end face 8 C, in which the elastomeric layer 4 forms an axial extension 9 which serves as a seal when the flanges of two successive pieces of hose are joined together.
Die Kabelschichten 2 und 3 sind radial gegen den Flanschteil 7 zurückgebogen und umgeben dabei die Rohrstücke IC. Zweckmäßig enden diese Schichten etwas vor dem Umfang 7 D des Flanschteiles 7. Nach dem Zurückbiegen der Schichten wird der Flanschteil 8 gegen die zurückgebogenen Teile der Schichten 2 und 3 gedrückt, worauf die Schicht 4 und die Auskleidung 6 in die kreisförmige Ausnehmung 8 D umgebogen wird. Um den Eintritt von Feuchtigkeit zwischen die beiden Flanschteile 7 und 8 zu verhindem, wird zwischen diesen Teilen an ihrem Umfang der vorhandene Hohlraum mit einer Füllmasse 10 aus Kautschuk oder einem sonstigen geeigneten Material ausgefüllt. Das Ganze wird alsdann unter Druckeinwirkung in üblicher Form vulkanisiert.The cable layers 2 and 3 are bent back radially against the flange part 7 and surround the pipe sections IC. These layers expediently end a little before the circumference 7 D of the flange part 7. After the layers have been bent back, the flange part 8 is pressed against the bent back parts of the layers 2 and 3, whereupon the layer 4 and the lining 6 are bent over into the circular recess 8 D. . In order to prevent the entry of moisture between the two flange parts 7 and 8, the existing cavity is filled between these parts on their periphery with a filling compound 10 made of rubber or some other suitable material. The whole is then vulcanized in the usual way under the action of pressure.
Das in F i g. 2 gezeigte Ausführungsbeispiel weicht von demjenigen nach Fig. 1 nur insofern ab, als die Flanschteile 7 bzw. 8 nicht nur eine einzige Auswölbung bzw. eine entsprechende Vertiefung, sondern zwei Auswölbungen 7£ auf der äußeren Stirnseite des Flanschteiles 7 bzw. zwei Vertiefungen 8 E auf der inneren Flanschseite des Flanschteiles 8 aufweisen. Diese Ausführung sichert ein zuverlässiges Festhalten der eingespannten Bewehrung, selbst beim Auftreten sehr hoher Kräfte, die die eingespannte Bewehrung aus der Einspannung zu lösen trachten.The in Fig. 2 embodiment shown differs from that of FIG. 1 only insofar as the flange parts 7 and 8 not only a single bulge or a corresponding recess, but two bulges 7 £ on the outer end face of the flange part 7 or two recesses 8 E have on the inner flange side of the flange part 8. This design ensures that the clamped reinforcement is reliably held in place, even when very high forces occur, which tend to loosen the clamped reinforcement from its clamped position.
