Abstract (en)

[origin: WO0136834A1] The invention relates to an elastic shaft coupling with at least one torsion element (1), comprising an elastomer body (3) as transfer element, axial connecting flanges (2), fixed to said element and ventilation channels therein. According to the invention, the radial ventilation channels (3a, 3b) are arranged in at least two axial planes, with an axial separation from each other, in order to improve the air cooling of the elastomer body and thereby prejudice the elastic and mechanical properties as little as possible.
