Patent EP-0367955-A1 (EP)
Inventor: JAMANN KARL-HEINZ DIPL-ING
IPC: F16J15/3276
Filed: 1989-09-21
Abstract: A shaft seal (1) for use in split receiving machine casings has on the outside circumference on the end face at least two toroidally extending regions (8) (9) of different diameters, the diameter of the region (8) with the larger diameter having the value specified for achieving a sufficient press fit in the casing, whereas the diameter of the second region (9) is slightly smaller. By this means, the pressing acting on the casing is smaller in total and pressing apart of the receiving machine casing in the split planes with adverse effects on the press fit and the static sealing is prevented. The cross-section (2) of the metallic casing ring galvanised on or in the elastomeric part of the shaft seal has a curved region (12) with a relatively large transition radius between the axial limb (4) and the radial limb (3), and the axial limb (4) is widened conically towards the front side (10) so that the casing ring yields under high forces acting during pressing-in and great pressing with pressing apart of the casing is prevented. <IMAGE>
