Abstract
A magnetic arrangement for transmitting torque from an input shaft (1) to an output shaft (2), of for example a pump, comprises at least one magnet arrangement (3, 4) assigned to each of the input shaft (1) and to the output shaft (2). A containment shell (5) comprising at least one inner sleeve (3) and at least one outer sleeve (4) extends between the magnet arrangements. An inner sleeve (3) is formed from at least one profile element (7) that extends approximately in the manner of a coil, as a unitary helical band with a mating protrusion and groove on opposite sides. An outer sleeve (4) is provided for axially fastening the profile element.
