Patent ID: 8852070

Claim:
A rotor bearing for a laboratory centrifuge, having a rotor which can be placed onto a shaft mounted so as to be able to rotate about an axis, having a locking system intended for axially securing the rotor, wherein the locking system consists of an arrangement of locking levers which are each mounted to be able to pivot about axes extending perpendicular to the axis between a locking position and an unlocking position in planes containing the axis, which locking levers, in the locking position, axially fix the rotor with respect to the shaft and that the locking levers can be transferred automatically and in dependence upon the rotational speed at least from the unlocking position into the locking position, and wherein the locking levers are mounted on the rotor and an annular groove is disposed on the shaft and is arranged to cooperate with the locking levers in the locking position whereby the locking levers create a force which draws the rotor axially toward the shaft.
