Ships propeller shaft seal - with concentric flanges and an excentric ring to support the intermediate ring
Реферат: The flanges are fastened for rotation with the propellor shaft, and have facing active side surfaces. The flanges clamp between them a plane-parallel intermediate ring. Pump elements constantly supply a lubricant to contacting flange and ring surfaces. The intermediate ring is suspended, so that it can rotate freely, and execute an eccentric movement radially. The ring is retained on at least one eccentric ring, to enforce an eccentric position of the intermediate ring in relation to the propeller shaft.
