Abstract

Es ist eine Zentrifuge mit einem Rotor bekannt mit mehreren jeweils an zwei Haltezapfen (4) gelagerten Schwenkbechern (3) und mit sektorförmigen in Richtung der Rotorachse im Rotor lagegesicherten Einsätzen (2) mit im wesentlichen vertikal ausgerichteten radial verlaufenden Tragwänden (12), die die Lagerkräfte der Haltezapfen (4) aufnehmen und deren radialer Außenbereich im Betriebszustand als Stützfläche dient, wobei jedem sektorförmigen Einsatz (2) zwei Haltezapfen (4) zugeordnet sind. Um eine Zentrifuge mit Schwenkbechern (3) derart auszubilden, daß sie sich durch ihren einfachen Aufbau auszeichnet und die ein Justieren der einzelnen Bauteile zueinander nicht erfordert, ist an jeder der beiden die Lagerkräfte aufnehmenden Tragwände (12) des Einsatzes (2) ein Haltezapfen (4) angeordnet, deren freie Enden einander zugekehrt sind. A centrifuge with one rotor is known, with several at two Retaining pin (4) mounted swivel cups (3) and with sector-shaped in the rotor in the direction of the rotor axis secured Inserts (2) with substantially vertically aligned radially extending support walls (12), which the bearing forces of the Pick up the holding pin (4) and its radial outer area serves as a support surface in the operating state, each being sector-shaped Insert (2) are assigned two retaining pins (4). To form a centrifuge with swivel cups (3) so that they are characterized by their simple structure and which does not require an adjustment of the individual components to each other, is on everyone of the two bearing walls (12) of the insert (2) absorbing the bearing forces, a holding pin (4) is arranged, the free ends of which are facing each other.
