Abstract

PURPOSE: To prevent the radial play of an intermediate seal ring and stabilize the sealing of a high-speed rotary shaft by disposing the intermediate seal ring between two seal rings, fitting a cylindrical body over the intermediate ring, and locating the end of the cylindrical boey close to the two seal rings.
CONSTITUTION: A seal ring 5 is fitted in a cover 2 through which a shaft 3 passes, a seal ring 6 is axially movably fitted over the shaft 3, and an intermediate seal ring 13 is diposed between the rings 5 and 6. A cylindrical body 14 is fitted over the ring 13 which is composed of radially split sectors. One end E of the cylindrical body 14 is placed close to the end face G of the ring 5, and the other end F close to the face H of the ring 6. When the shaft 3 rotates, the radial displacement of the ring 13 is prevented by the faces G and H, the position of the ring 13 is stabilized, and the shaft sealing is made safe.
