  • Patent number: 7850590
    Abstract: A separator includes a centrifuge drum having a vertical rotational axis and a feed line to feed a product to be centrifugally processed. Further included is a drive spindle having an impeller to drive the centrifugal drum, which drive spindle is rotatably mounted in a housing by a bearing device and which is supported on a machine frame by an elastic support. Also included is a lubrication arrangement and a drive device including an electric drive motor having a stator and a motor rotor which is aligned with the drive spindle.

  • Patent number: 7090634
    Abstract: A driving system for a separator having a centrifugal drum with a vertical axis of rotation. The driving system includes a vertically aligned driving spindle configured to accommodate a centrifugal drum. The driving spindle is arranged by a neck bearing and a footstep bearing in an opening of a drive housing. The neck bearing is supported in an axially rigid and radially resilient manner on the machine housing. The neck bearing is constructed as an angular ball bearing and supports the centrifugal drum on a spherical-shaped supporting surface of the machine housing.
