Patent number: 10300499Abstract: A centrifuge having a driveshaft that has an end section that tapers toward the central axis of the driveshaft. A rotor is removably mounted on the driveshaft such that the rotor may be axially removed in a removal direction. A bearing surface of a locking element of the rotor is connected to the driveshaft and holds the rotor against removal. A quick-action closure is integrated into the rotor and prevents removal of the driveshaft and the rotor in the removal direction. The end section of the driveshaft extends through an opening in the rotor where it is partially surrounded by multiple locking elements of the rotor for fixing the rotor and the driveshaft together. The locking elements include bearing surfaces engaging the end section and support surfaces engaging the rotor. The quick-action closure has force-transmitting elements which connect the locking elements to a handle permitting locking and/or unlocking the quick-action closure by a respective movement of the handle.Type: GrantFiled: July 10, 2014Date of Patent: May 28, 2019Assignee: ANDREAS HETTICH GMBH & CO.
