Abstract
A slide ring seal is used for sealing a stationary part against a rotating shaft. It comprises a primary slide ring and a bellows-shaped ring-form secondary seal. Spring parts press the secondary seal radially against the slide ring and the rotating shaft. A central spring part exerts an axial force on the secondary seal which at most locates against the secondary seal with less radial tension than is the case with the first and second spring parts. The first (16) and secondary (7) spring parts are separated from the central spring part (18), and are pref. formed as round wire spring rings. They can alternatively be formed as open discs. The central spring part (18) is a screw ring.
