Abstract
PURPOSE: To enlarge flexibility, to increase follow-up performance to the oscillation of a shaft and to improve sealing performance by a method wherein on the surface of the reverse side of a sealed slide surface are provided a plurality of radial grooves.
CONSTITUTION: A circular seal lip 1 is inserted into a supporting ring 2 and pressed by a holding ring 3 on the supporting ring 2. The seal lip has an arc from and its internal circumference is pressed on and attached to a shaft 4 to form a sealed slide surface S. The external circumference of the supporting ring 2 is pressed by force in a casing 5, a spring ring 6 presses the seal lip on the shaft 4 to increase the contact pressure of the sealed slide surface S. On the surface of the reverse side of the sealed slide surface S in the seal lip 1 are provided a plurality of radial grooves. When the shaft 4 is rotated, sealed fluid L is sealed on the sealed slide surface S. When the shaft 4 oscillates, the seal lip 1 is deformed according to the oscillation and the contact with the slide surface S is kept.
