Rotor arrangement for centrifuge with drive shaft

摘要

Axially arranged in the aperture is a nave connected with the drive shaft. The nave has a lower part and an upper part, which is engaged positively with the rotor. The lower part (4) and/or the upper part (5) of the nave (3) have/has edge parts (8), which locate on the outside of the raised formations (7) rising towards the nave. The raised formations on the under side and/or upper side of the rotor (1) are formed as all-round convolutions. The outsides of the raised formations rise in a straight line outwards from the under side or upper side of the rotor to the nave.
