Abstract

A tensioning assembly having a cylindrical exterior circumferential surface of a drivable shaft section and an interior cone ring having a cylindrical interior circumferential surface arranged on the cylindrical exterior circumferential surface, the interior cone ring having a conical exterior circumferential surface. An exterior cone ring is arranged on the conical exterior circumferential surface of the interior cone ring, the exterior cone ring having tensioning screws which are coaxial with respect to the drivable shaft section and by which the interior and exterior cone rings are tensioned with one another and the interior cone ring is tensioned with the drivable shaft section. To provide a tensioning assembly that is easily mounted and relaxed without loosening of the tensioning screws, a driven sleeve is arranged on the shaft section and is coupled to a driven element, the driven sleeve having an axial length that is larger than an axial length of the interior and exterior cone rings by the axial length of the driven element. Grooves are provided in at least one of the cylindrical circumferential surfaces, the grooves admitting a liquid pressure medium to the pairing of the …
