A SEPARATING DISK AND A DISK PACKAGE FOR A CENTRIFUGE ROTOR

摘要

The invention refers to a separating disk and a disk package for a centrifuge rotor of a centrifugal separator for separation of components in a supplied medium. The separating disk (20) extends around an axis (x) of rotation and has a tapering shape along the axis (x) of rotation with an inner surface and an outer surface (21 ). The separating disk is manufactured of a material. The separating disk comprises a number of distance members (25) extending at a certain height away from at least one of the inner surface and the outer surface. The tapering shape of the separating disk has been provided through pressing of a blank of the material against a tool having a shape corresponding to the tapering shape of the pressed separating disk. The separating disk has a thickness which varies with the distance from the axis of rotation. The height of the distance members (25) varies with the distance from the axis (x) of rotation in such a way that this varying height compensates for the varying thickness.
