  • Patent number: 9211580
    Abstract: The invention refers to a method and a press tool for manufacturing of a separating disk adapted to be included in a disk package of a centrifugal separator. The separating disk extends around an axis of rotation and has tapering shape with an inner surface and an outer surface along the axis of rotation. The separating disk is manufactured of a material and comprises a number of distance members in form of pressed protrusions extending away from the inner surface and/or outer surface. A blank of the material is pressed against the first tool part having a shape corresponding to the tapering shape of the pressed separating disk and comprises first form elements having a shape corresponding to the protrusions.

  • Patent number: 8678989
    Abstract: A separating disk for a disk package of a centrifuge rotor of a centrifugal separator has a tapering shape and extends around an axis of rotation and along a tapering rotary symmetric surface along the axis of rotation. There is an interspace between the separating disk and an adjacent separating disk. The separating disc has first protrusions extending outwardly from the tapering rotary symmetric surface and second protrusions extending inwardly from the tapering rotary symmetric surface. Each of the first and second protrusion are after each other in a peripheral direction and define a contact zone adapted to abut an adjacent separating disk in the disk package. The contact zones of the first protrusions are displaced in relation to the contact zones of the second protrusions seen in a normal direction with regard to the outer surface. Each contact zone has a continuously convex cross sectional shape.

  • Patent number: 8562503
    Abstract: The invention refers to a disk package for a centrifuge. The disk package comprises a plurality of separating disks provided on each other in the disk package. Each separating disk extends around an axis of rotation for the centrifuge rotor and has tapering shape with an inner surface and an outer surface along the axis of rotation. Each separating disk has inner edge, defining a central opening of the separating disk, and outer edge. Each separating disk is manufactured of a material. The separating disks comprise a plurality of first separating disks comprising a number of distance members, which extend away from the inner surface and/or outer surface. Each distance member comprises at least one contact zone abutting an outer surface and inner surface, respectively, of an adjacent separating disk in the disk package. The contact zone has a continuously convex shape seen in a cross section.

The separating disk extends around an axis of rotation and has a tapering shape with an inner surface and an outer surface along the axis of rotation. A blank of a material is provided. A central opening is made in the blank. The blank is positioned in a charging position by means of a projecting central portion. The blank is pressed against the first tool part having a shape corresponding to the tapering shape of the separating disk.

  • Publication number: 20110195832
    Abstract: A separating disk for a disk package of a centrifuge rotor has a tapering shape and extends around an axis (x) of rotation, and along a rotary symmetric surface. The separating disk is configured in such a way that it creates an interspace between the separating disk and an adjacent separating disk in the disk package, and comprises first protrusions extending outwardly from the rotary symmetric surface and second protrusions extending inwardly from the rotary symmetric surface. Each first and second protrusion defines a contact zone adapted to abut the adjacent separating disk. The contact zone of the first protrusions is displaced in relation to the contact zone of the second protrusions. The first and second protrusions are provided after each other in the peripheral direction of the separating disk.
