The invention relates to a centrifuge (10) having a driveshaft (12) which has an end region (13b) that tapers towards the central axis (11) of the driveshaft (12), a rotor (18) which is mounted on the drive shaft (12) and which can be axially removed in a removal direction (16), a bearing (20) for the rotor (18), said bearing being connected to the driveshaft (12) and holding the rotor (18) at least against the removal direction (16), a quick closure (22) which is integrated into the rotor (18) and by means of which the driveshaft (12) and the rotor (18) are fixed in the removal direction (16), and an opening (24) in the rotor (18), the driveshaft (12) engaging with the end region (13b) through said opening, which is delimited by an opening wall (26) of the rotor (18). Multiple locking elements (30) are provided on the rotor side for fixing the rotor (18) and the driveshaft (12), said locking elements at least partly surrounding the end region (13b) in order to fix the rotor (18) relative to the driveshaft (12). Bearing surfaces (30a) of the locking elements (30) rest against the end region (13b), said bearing surfaces pointing in the removal direction (16), and support surfaces (30b) of the locking elements (30) rest against the opening wall (26) of the rotor (18), said support surfaces pointing away from the removal direction (16), wherein the support surfaces of the locking elements (30) form an outer circumference which is larger than the inner circumference of the opening (24) when the locking elements are resting against the opening wall. The invention is characterized in that the end region (13b) has an expanded section which tapers into a remaining section of the driveshaft (12), the quick closure (22) has force-transmitting elements (32) which connect the locking elements (30) to a handle (36), and the quick closure (22) is locked and/or unlocked by a respective movement of the handle (36) and the force-transmitting elements (32) in a direction parallel to the drive axis. |
