Abstract
A sleeve for sealing a jointed connection is designed in the form of an elastically deformable bellows. On the two ends of the bellows, there are axially aligned ring flanges, which fix the sleeve on a cylindrically shaped fastening flange, and on a shaft, using a muzzle hoop. For fixing fastening flanges of different sizes, several ring flanges have stepped diameters and are lined up in a row. A radially inwardly drawn rib is shaped by molding on the inner end of the ring flange. The rib sealingly rests against the face side of the fastening flange. For achieving an adequate sealing effect, the inside diameter of the rib is smaller than or equal to the inside diameter of the next-smaller ring flange.
Claims6
A sleeve for sealing a jointed connection, comprising:
- an elastically deformable bellows having two ends;
- a plurality of axially aligned and differently sized ring flanges lined up between said two ends, said ring flanges fixing the sleeve on a cylindrically shaped fastening flange and on a shaft via a muzzle, said ring flanges each having an inside diameter, an inner end and an outer end and being arranged step-wise with increasing diameters from one end of the bellows to the other end to accommodate differently sized fastening flanges, with an inner end of one ring flange adjacent an outer end of the next smaller ring flange;
- at least one radially inwardly drawn rib having an inside diameter and connected to the inner end of at least one of said ring flanges, said rib being shaped by molding on the inner end of the ring flange and sealingly abutting a face side of the fastening flange, wherein the inside diameter of the rib is smaller than or equal to the inside diameter of the next-smaller ring flange.
