Title (EN) ELASTIC SHAFT COUPLING
(FR) SYSTEME DE COUPLAGE D'ARBRES ELASTIQUE
(DE) ELASTISCHE WELLENKUPPLUNG
Abstract:
(EN) The invention relates to an elastic shaft coupling with at least one torsion element (1), comprising an elastomer body (3) as transfer element, axial connecting flanges (2), fixed to said element and ventilation channels therein. According to the invention, the radial ventilation channels (3a, 3b) are arranged in at least two axial planes, with an axial separation from each other, in order to improve the air cooling of the elastomer body and thereby prejudice the elastic and mechanical properties as little as possible.
(FR) La présente invention concerne un système de couplage d'arbres élastique comprenant au moins un élément de torsion (1) qui présente un corps élastomère (3) en tant qu'élément de transmission, des brides de raccordement axiales (1, 2) étant fixées audit corps élastomère et ledit corps élastomère présentant des canaux de ventilation. Pour améliorer le refroidissement du corps élastomère (3) tout en altérant au minimum les caractéristiques élastiques et mécaniques, les canaux de ventilation radiaux (3a, 3b) de l'invention se trouvent dans au moins deux plans axiaux séparés par une distance axiale.
(DE) Die vorliegende Erfindung betrifft eine elastische Wellenkupplung mit mindestens einem Torsionselement (1), welches als Übertragungselement einen Elastomerkörper (3) aufweist, an dem axiale Anschlußflansche (2) befestigt sind und der Belüftungskanäle aufweist. Um die Luftkühlung des Elastomerkörpers (3) zu verbessern und dabei die elastischen und mechanischen Eigenschaften möglichst wenig zu beeinträchtigen, schlägt die Erfindung vor, daß die radialen Belüftungskanäle (3a, 3b), in mindestens zwei Axialebenen angeordnet sind, die axialen Abstand voneinander haben.
