Claims (3)

프로펠러축에 자성재료로 된 라이너가 절연링을 통하여 씌어 끼워지고, 상기 라이너의 외주상에 축방향 간격을 두고 시일링이 씌어지고, 상기 시일링간의 라이너 외주상에 자성유체축 시일이짜 넣어진 선미관 시일장치로서, 상기 자성유체축 시일은, 라이너 외주측과의 사이에서 공기실을 형성하여 씌어끼워진 링상 자석과, 상기 자석의 전후에 장착되어 라이너 외주측과의 사이에서 각각 공기실을 형성하여 씌어끼워진 링상 폴 블록과, 상기 폴 블록과 각각 축방향으로 대면하는 상기 시일링과의 사이에서 라이너의 외주상에 개재된 자성유체와로 구성되어 있는 것을 특징으로 하는 선미관 시일장치.A stern with magnetic material liner is fitted to the propeller shaft through an insulating ring, a sealing ring is applied at an axial interval on the outer circumference of the liner, and a magnetic fluid shaft seal is squeezed on the outer circumference of the liner between the sealing rings. As the tube sealing device, the magnetic fluid shaft seal includes a ring-shaped magnet sandwiched by forming an air chamber between the liner outer circumferential side, and an air chamber formed between the liner outer circumference and mounted before and after the magnet. And a magnetic fluid interposed on an outer circumference of the liner between the ring-shaped pole block sandwiched and the seal ring facing the pole block in the axial direction, respectively. 제1항에 있어서, 상기 폴블록의 각각에는 시일링의 서포오트부가 형성되고 상기 서포오트부의 각각에 시일링이 장착되고 상기 시일링의 리프가 라이너의 외주상에 접접되어 있으며 이 접접부에 각각 지향하여 자성유체 공급로의 토출부가 상기 폴 블록의 각각에 형성되어 있는 것을 특징으로 하는 선미관 시일장치.2. The seal of claim 1, wherein each of the pole blocks has a supporting portion of a sealing ring, a sealing ring is mounted on each of the supporting portions, and a leaf of the sealing ring is in contact with the outer circumference of the liner. And a discharge section of the magnetic fluid supply path is formed in each of the pole blocks. 제1항에 있어서, 상기 시일링의 공기측인 배면에 자성재료로 된 탄성 변형가능한 금속링이 장착되고 상기 시일링이 자성재료로 된 회전축측에 씌어 끼어져서 상기 금속링과 회전축측과의 협동으로 내주 리프근처의 배면측에 자장이 형성되며 다시 이 자장에 자성유체가 봉입되어 있는 것을 특징으로 하는 선미관 시일장치.2. An elastically deformable metal ring made of a magnetic material is mounted on an air back side of the seal ring, and the seal ring is caught on a side of a rotating shaft made of magnetic material so that the metal ring cooperates with the side of the rotating shaft. And a magnetic field is formed on the rear side of the inner circumference near the leaf, and the magnetic fluid is sealed in the magnetic field. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
