Abstract

Le dispositif comprend deux joints de frottement assurant l'étanchéité et montés en série le long de l'arbre 53 entre celui-ci et la structure 67 qui l'entoure, avec un espace vide 68 entre les deux joints. Un conduit de drainage 69 part de l'espace et un récipient 40 disposé sur ce conduit indique l'entrée de liquide dans ledit espace. Les joints de frottement sont formés par un collet angulaire 55 s'étendant radialement à partir de l'arbre et par des anneaux d'usure 59, 60 poussés axialement contre les faces radiales opposées 56, 57 de ce collet. Presse-étoupe, notamment de gros navires de mer, évitant toute pollution de la mer et remis rapidement en état par remplacement des anneaux d'usure.
