Abstract

PURPOSE: To prevent the radial play of an intermediate seal ring which is located between a fixed seal ring and a rotary seal ring and to stabilize the sealing of a high-speed rotary shaft by providing an annular-rugged surface on the side portion of the intermediate ring and providing the intermediate ring with sylindrical portions.
CONSTITUTION: A casing 1 is fitted with non-rotary seal ring 2, and a shaft 3 is passed therethrough. A rotary seal ring 4 is axially movably fitted over the shaft 3. Between the rings 2 and 4 is disposed an intermediate seal ring 12, of which the faces 13 and 14 are provided with rugged surfaces to enhance the close contact with the side faces 15 and 16 of the rings 2 and 4. The outer periphery of the ring 12 is extended to form cylindrical portions 17 and 18 which are close to the rings 2 and 4. When the shaft 3 rotates at high speed, the radial play of the ring 12 is prevented and the sealing is made safe.
