る船尾管シール装置。A cylindrical liner 4 made of a magnetic material is fitted onto the propeller shaft 2 via an insulating ring 5, and seal rings 11 and 12 are fitted onto the outer periphery of the liner 4 at intervals in the axial direction. This is a stern tube sealing device in which a magnetic fluid shaft seal 26 is incorporated on the outer circumference of the liner 4 between 11° and 12, and the magnetic fluid shaft seal 26 forms an air chamber 21 with the outer peripheral side of the liner 4. A ring-shaped magnet 14 is fitted with a ring-shaped magnet 14, and a liner is attached to the front and rear of the magnet 14.
-4 ring-shaped pole blocks 15.15 each forming an air chamber 20.22 between them and the outer circumferential side thereof and being fitted therein;
a magnetic fluid 18.18 interposed on the outer periphery of the liner 4 between the pole block 15.15 and the seal rings 11, 12 facing each other in the axial direction; 15.15 each has a support portion 15A, 1 of the seal ring 11.12.
5A is formed, a seal ring 11.12 is attached to each of the support portions 15A, 15A, and the lips IIA, 12A of the seal rings 11, 12 are in sliding contact with the outer periphery of the liner 4. A stern tube sealing device characterized in that discharge portions 17A of the magnet fluid supply path 17 are formed in each of the pole blocks 15 and 15, respectively, so as to be oriented toward the respective pole blocks.
