Abstract
A centrifuge includes a drum with a vertical axis of rotation, a drive spindle mounted by a neck bearing and a foot bearing in a rotatable manner in or on a machine frame, and a drive motor. The neck bearing is axially displaceable and radially supported. A spring is arranged centrally below the foot bearing, the spring supporting the unit of the drum, drive spindle, neck bearing, and foot bearing in a sprung manner and deflectable in an axially limited manner with respect to the machine frame. The axially limited deflectability of the working spindle is achieved in that the foot bearing is mounted, by way of its outer ring, in a sleeve which is arranged on the spring.

A centrifuge comprising:
- a centrifuge drum with a vertical axis of rotation, wherein a disk stack is arranged in the centrifuge drum;
- a drive spindle of the centrifuge drum rotatably mounted in or on a machine frame by a neck bearing and a foot bearing, wherein the neck bearing is axially displaceable and radially supported, and wherein the drive spindle is axially deflectable;
- a drive motor coupled to and configured to drive the drive spindle;
- and
- a spring arranged centrally under the foot bearing of the drive spindle, wherein the spring supports a unit consisting of the centrifuge drum, the drive spindle, the neck bearing, and the foot bearing in an axially limited deflectable resilient manner with respect to the machine frame,
- wherein the foot bearing includes an outer ring,
- wherein the outer ring of the foot bearing is mounted in a sleeve arranged on the spring,
- wherein the centrifuge is a separator configured to separate, in a centrifugal field, a product to be processed into a solid phase and into at least one liquid phase, and
- wherein the centrifuge is designed for use on a ship.
