DOUBLE END SEAL Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: double end seal relates to seals of rotating shafts. It has a body where axially-moving rings are positioned. Working end surfaces of rings are installed opposite to working end surfaces of supporting ring positioned on shaft. Every working end of ring contains circular magnet. Magnets are facing each other with their similar poles. Skewing between rings and supporting ring gives rise to moment which tends to restore plane-parallelism of working end surfaces of rings which promotes more reliable operation of seal. EFFECT: improved design. 2 cl, 2 dwg
