Abstract
A centrifuge including a drive head attached to a rotation shaft and a rotor adapted to be removably mounted on the drive head in a rotational driving position and which is coupled thereto during rotation of the drive head. The centrifuge includes elements for axially locking the rotor to the drive head by applying to the rotor an axial retaining force that increases with the rotational speed of the drive head.
Claims10
A centrifuge comprising;
- a rotational drive head attached to a rotational shaft so as to rotate about a rotational axis, the drive head having a retaining surface, a rotor adapted to be removably mounted on the drive head in a rotational driving position and having a bearing surface for engaging said retaining surface of said drive head, coupling means for coupling the drive head and the rotor in rotation, a locking means for axially locking the rotor to the drive heading including means for applying to the rotor an axial force for retaining the bearing surface of the rotor against the retaining surface of the drive head which force increases with the rotational speed of the drive head.
