Abstract

PURPOSE: To offer a shaft sealing with long life with such a construction that an intermediate sealing ring is interposed between a rotary sealing ring and a stationary sealing ring and the contact faces of this intermediate sealing ring with the other rings shall have bends in order to engage themselves.
CONSTITUTION: On the outside surface of the shaft 3 piercing a casing 1, whose end a sealing ring 2 is fixed to, a sealing ring 4 is fitted with mobile possibility in the axial direction as well as an end ring 6 is fixed using a knock 7. A spring 8 is interposed between the sealing ring 4 and the end ring 6, and one of its ends shall be put on the cylindrical periphery 9 of the sealing ring 4 while the other end on the cylindrical periphery 10 of the end ring 6. An intermediate sealing ring 15 is interposed between these sealing rings 2, 4 with rotary possibility, and the contact faces 17, 16 of this intermediate ring 15 with the other rings 2, 4 shall have bends in order to engage themselves. The intermediate sealing ring 15 shall be made of fluoric resin and designed so that wear of the contact faces 16, 17 is absorbed with the air of the spring 8.
