Sealing bellows and sealing arrangement comprising the sealing bellows

A sealing bellows made of an elastomeric material, comprising:

• a first end face;
• a second end face;
• and
• a casing having a central axis, the casing being arranged in an axial direction between the first and second end faces, the casing comprising at least one torsion-compensating element configured to absorb torsional movements introduced into the sealing bellows substantially without torsional stress,
• wherein the first end face comprises a first static seal and the second end face comprises a second static seal,
• wherein the sealing bellows comprises a TPE material,
• wherein the torsion-compensating element comprises an origami structure having folding elements which are connected to one another in a relatively movable manner by bends,
• wherein the folding elements are movable relative to one another when torsional movements are introduced into the sealing bellows in a circumferential direction of the casing,
• wherein the origami structure comprises three-dimensional basic shapes with the folding elements,
• wherein each basic shape comprises a concave hexagonal pyramid, an apex of which is disposed in a direction of the central axis of the sealing bellows,
• wherein the basic shapes are arranged on an imaginary first radial plane of the casing and adjacent to one another in the circumferential direction,
• wherein an imaginary second radial plane of the casing is arranged axially adjacent to the imaginary first radial plane of the casing, in which further three-dimensional basic shapes are arranged adjacent to one another in the circumferential direction, and
• wherein the basic shapes in the first and the second imaginary radial planes are each arranged offset relative to one another, seen in the circumferential direction, by half a basic shape.
