ABSTRACT:
The invention relates to a slide ring seal for sealing a shaft rotatable with respect to a wall, which seal comprises a body portion and seal rings provided with slide rings, which seal rings are so arranged with respect to each other that the sealing slide faces of the slide rings are pressed against each other and rotate with respect to each other. Each slide ring is fastened in the seal ring thereof by a shrink fit, whereby the peripheral face of the slide ring is in engagement with a face provided on the seal ring, so that the radial press force of the shrink fit is directed to act on a centroid of the cross-sectional area of the slide ring. In order to ensure that the forces of the shrink fit keep acting accurately on the centroid of the cross-sectional area of the slide ring, at least one of the faces which are in engagement with each other in the shrink fit is convex. The highest point of the convex surface is in a radial plane extending through the centroid of the cross-sectional area of the slide ring.
