Abstract
This anti-lead seal prevents the accumulation of torsional and tangential stresses on one and the same sealing element by way of an intermediate sleeve (6) which forms an axial seal gap (7) with one of the coordinated corrugated or housing-like machine parts (1, 2) and a radial seal gap (8) with the other. Since the intermediate sleeve (6) is firmly retained via a torsional safety (11) and an axial fixation (13), the sealing elements (9) for the radial seal gap (7) are stressed only by relative axial movements and the sealing elements (12) for the axial seal gap (8) are stressed only by rotational movements. Here simple elastomeric parts can be used that are easy to supply and can be quickly mounted.
