Rotor for a magnetic stirring device and magnetic stirring device

摘要

The present invention relates to a rotor (1) for a magnetic stirring device (100), comprising a rotor element (10) and an arrangement element (30), wherein at least one magnetic element (15) is arranged on and / or in the rotor element (10) for generating a rotational movement of the rotor element (10) about an axis of rotation (R) when subjected to a rotating magnetic field, wherein the arrangement element (30) further comprises a central portion (31) having a placement portion (32) for locating at a counter assembly portion (103) of a central In addition, the rotor element (10) has two transverse to the axis of rotation (R) oriented Rotorgleitflächen (14) and the arrangement element (30) has two at the central portion (31) arranged holding elements (34) each having a transverse to the axis of rotation ( R) oriented Haltegleitfläche (35), and further wherein in pairs each have a Rotorgleitfläche (14) and a Haltegleitfläche (35) for however, in sections contacting each other are arranged to provide a rotary slide bearing of the rotor element (10) and an axial fixing of the rotor element (10) on the arrangement element (30). The invention further relates to a magnetic stirring device (100) having a central axle element (101), a rotor (1) arranged on the central axle element (101) and a magnetic drive for applying a rotating magnetic field to a rotor element (10) of the rotor (1) Generating a rotational movement of the rotor element (10) about an axis of rotation (R).
