Abstract

A method and apparatus for securing a rotor to a drive cone in a centrifuge includes positioning a rotor upon a drive cone and providing a nut movable in an axial direction in the drive cone. A screw passing through a region of the rotor engages the nut, and a spring is located between a surface of the nut and a surface of the drive cone. By tightening the screw into the nut, the nut moves in an axial direction to compress the spring between the surface of the nut and the surface of the drive cone. The arrangement of the screw, nut, and spring prevents a loosening of the screw from the nut during operation of the centrifuge.
