Abstract

PURPOSE: To raise the vibration resistance of a mechanical seal, the axial moving property and safety of a seal ring and the moving tolerance of a shaft, by W-shaping the cross section of an annular packing which supports the seal ring having a contact surface.
CONSTITUTION: The packing 7 has an outer cylinder 14 and an inner cylinder 15, which are set in pressural contact with an inner cylindrical surface 22 and an outer cylindrical surface 24 by push rings 21, 23 and coupled to each other by a diaphragm part 16. As a result, the inside of the seal ring 6 and the outside of the shaft 3 are completely sealed up to each other. Since the diaphragm part 16 is very flexible, the buffer property of the packing 7 is high enough to prevent vibration from being transmitted to the contact surface S. Because the outer cylindrical surface 24 or the inner cylindrical surface 22 slides and/or the diaphragm part 16 is deformed, the axial moving property and safety of the seal ring 6 and the moving tolerance of the shaft 3 are raised.
