INRICHTING VOOR HET AFDICHTEN VAN SCHROEFAANDRIJVINGEN VOOR SCHEPEN MET TWEE CONCENTRISCHE, CONTRA-ROTERENDE SCHROEFASSEN.

摘要

A seal arrangement for controlling any large bearing clearance in the vicinity of a propeller shaft, such as for a propeller drive system for ships with two concentric propeller shafts rotating in opposite directions, has a housing ring for supporting the sealing lips and a supporting ring for supporting the housing ring and defining a clearance therebetween. This clearance can be sealed, and maintained by using elastic ring walls disposed between and interconnecting the housing to the supporting ring, so that compensation can be achieved for changes in the clearance during rotation of the propeller shaft.
