Abstract

The invention relates to a coupling between an inner pipe and an outer pipe concentric to the latter, comprising a body arranged between the mutually facing circumferential surfaces of the two pipes and consisting of rubber or a similar flexible material. According to the present invention, the flexible body is permanently connected to the circumferential surface of the inner pipe by vulcanisation or the like, while it engages by means of tongues and/or grooves in corresponding grooves and/or tongues on the circumferential surface of the outer pipe, and the flexible body is thicker in the unloaded condition than the difference between the inner radius of the outer pipe and the outer radius of the inner pipe, with the result that, in the coupling position, it is compressed between the two pipes. In addition, the flexible body has a conical taper at at least one end on the outside provided with the tongues and/or grooves.

Kennzeichnend für dieselbe ist, daß der elastische Körper durch Vulkanisierung o. dgl. fest mit der Mantelfläche des Innenrohrs verbunden ist, wogegen er mit Federn und/oder Nuten in demselben in entsprechende Nuten und/oder Federn an der Mantelfläche de Außenrohres eingreift, daß uer elastische Körper in unbelastetem Zustand größere Materialstärke hat als dem Unterschied zwischen dem Innenradius des Außenrohres und Außenradius des Innenrohres enspricht, so daß er in Kupplungsstellung zwischen den beiden Rohren komprimiert ist, sowie daß der elastische Körper zumindest am einen Ende konisch an der mit den Federn und/oder Nuten versehenen Außenseite verjüngt ist. Da der elastische Körper nur mit dem einen Rohr fest verbunden ist, wird das Herstellen und Montieren der Kupplung erleichtert. Hierzu kommt der weitere Vorteil, daß Nuten und Federn, die ein gegenseitiges Verdrehen der Rohre verhindern, eine Verschiebungsbewegung zwischen den Rohren gestatten.between an inner and outer tube concentric thereto, wherein the coupling from one between the mutually facing lateral surfaces of the pipes arranged body made of rubber or similar elastic material. Characteristic for the same is that the elastic body by vulcanization o. The like. Firmly with the outer surface of the inner tube is connected, whereas it is connected with tongues and / or grooves in the same in corresponding grooves and / or tongues on the outer surface of the outer tube intervenes that uer elastic body greater material thickness in the unloaded state has as the difference between the inner radius of the outer tube and the outer radius of the inner tube, so that it is in the coupling position between the two tubes is compressed, and that the elastic body is conical at least at one end is tapered on the outside provided with the tongues and / or grooves. Since the elastic body is firmly connected only to the one pipe, is the manufacture and mounting of the coupling facilitated. In addition, there is the further advantage that grooves and springs, which prevent the tubes from rotating with respect to one another, a displacement movement allow between the pipes.

The elastic body 3 j't hlerbei by vulcanizing or the like firmly connected to the outer surface of the inner tube 1, while he is with springs 5 and / or Grooves 6 in ent computing, grooves 7 and / or tongues 8 on the jacket surface 9 of the outer tube 2 intervenes. The elastic body 3 has the shape of a hollow cylinder and is solid connected to the inner tube 1, whereas it is non-rotatable but displaceable in the outer tube 2 is seated.

Der elastische Körper 3 hat in unbelastetem Zustand größere Material stärke als dem lJnterschied zwischen dem Innerradis des Außenrohres 2 und Außenradius des Innenrohres 1 entspricht. Der Körper 3 ist somit mehr oder weniger in Kupplungsstellung zwischen den beiden Rohren 1 und 2 komprimiert.The elastic body 3 has larger material in the unloaded state than the difference between the inner radius of the outer tube 2 and the outer radius of the inner tube 1 corresponds. The body 3 is thus more or less in the coupling position compressed between the two tubes 1 and 2.

Um die Montage der Kupplung zu erleichtern, d.h. das Einführen des Rohres 1 mit dem Körper 3 in das Rohr 2, ist der Körper 3 wenigstens am einen Ende 10 konisch bei 11 auf der mit den Federn 5 und/oder Nuten 6 versehenen Außenseite 12 verjüngt.In order to facilitate the assembly of the coupling, i.e. the insertion of the Tube 1 with the body 3 in the tube 2, the body 3 is at least at one end 10 conically at 11 on the outside provided with the tongues 5 and / or grooves 6 12 tapers.
