Abstract

Die Erfindung betrifft eine Kupplung in der Trockenpartie einer Faserbahnmaschine, welcher Kupplung - ein nicht drehbar eingebauter Kupplungsrahmen (21) umfassend Anschlüsse (13, 23) für das Kondensatwasser und/oder den Dampf am Ende des Kupplungsrahmens (21), - ein Ringkolben (25) nicht drehbar am Kupplungsrahmen (21) eingebaut, aber federbelastet und axial beweglich durch eine axiale Trommelfläche (21a) gesteuert, - eine mit dem Ringkolben (25) verbundene direkte radiale Dichtungsfläche (31a), - ein mit der Achse (10c) verbundenes Gegenstück und eine daran angeordnete drehbare kugelartige Dichtungsfläche (29a), deren Radius r 55 - 75 %, bevorzugter 58 - 70% mal den Außendurchmesser Du der Kohlenringdichtung (28) beträgt, - eine zwischen der kugelförmigen Dichtungsfläche (29a) und der mit dem Ringkolben (25) verbundenen Dichtungsfläche (30a) angeordnete schwimmende Kohlenringdichtung (28), während die Federung des Kolbens (28) und der Gegendruck die Dichtungsflächen (28a, 29a) zusammendrücken, zugeordnet sind.
