An attachment fitting is attached inside a rotor hole. The attachment fitting is made up of a main body, first and second pieces disposed in a piece placement hole formed in the main body so as to pass therethrough in a direction orthogonal to a rotation central axis of a rotor, a leaf spring including two arm portions, and a retainer that is mounted on the main body and puts a base of the leaf spring between the retainer and the main body. The first and second pieces have grooves into which the arm portions of the leaf spring are inserted. When the rotor rotates, the first and second pieces protrude from the piece placement hole by the centrifugal force against the spring force of the leaf spring and make contact with a rotor coupling portion of a shaft.

An attachment fitting is attached inside a rotor hole. The attachment fitting is made up of a main body, first and second pieces disposed in a piece placement hole formed in the main body so as to pass therethrough in a direction orthogonal to a rotation central axis of a rotor, a leaf spring including two arm portions, and a retainer that is mounted on the main body and puts a base of the leaf spring between the retainer and the main body. The first and second pieces have grooves into which the arm portions of the leaf spring are inserted. When the rotor rotates, the first and second pieces protrude from the piece placement hole by the centrifugal force against the spring force of the leaf spring and make contact with a rotor coupling portion of a shaft. In a structure that allows the rotor to be attached to the shaft by simply being put onto the shaft, assembly on the rotor's side can be easily performed.

A rotor of a centrifugal separator, wherein the rotor comprises a central shaft on which an axially movable plate stack, formed by multiple plates, is arranged. A stack base is arranged on the shaft under the plate stack. A stack cap is arranged in an axially moveable manner on the shaft above the plate stack. The rotor includes a compression spring surrounding the shaft, with a first end supported on the shaft and a second end supported on the stack cap, pressing the plate stack together. The rotor includes a sleeve-like extension arranged on the stack cap, projecting into the plate stack and surrounding the shaft with a separation. The compression spring is located inside the extension, at least over a majority of the axial length thereof. A support surface for the second end of the compression spring, is arranged on a base of the extension.

The invention relates to a centrifuge (10), having a drive shaft (12), a rotor (14), which is mounted on the drive shaft (12) and is axially removable in a removal direction (26), a quick closure (20), which operates between the rotor (14) and the drive shaft (12) and by means of which the rotor (14) can be fixed relative to the drive shaft (12) in the removal direction (26), a thrust bearing (44) connected to the drive shaft (12), a locking bearing (24) connected to the rotor (14), at least one blocking element (38), which, when activated, fixes the rotor (14) relative to the drive shaft (12) and operates between the locking bearing (24) of the rotor (14) and the thrust bearing (44) of the drive shaft (12). The pivot axis (38b) is aligned perpendicular to a straight line parallel to the drive shaft (12) and the blocking element (38) has a cardan shaft (38a), which is rotatable about the pivot axis (38b), and is connected to a bearing (40) via the cardan shaft (38a).

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.

A vacuum centrifuge (10) has a housing (15) and a vacuum chamber (14a) which is disposed in the housing (14) and is connected to a vacuum pump (26) via a suction line system (24, 48) in order to generate a required vacuum in the vacuum chamber (14a). The vacuum centrifuge (10) has a rotor (12), mounted rotatably about its rotor axis (12a) in the vacuum chamber (14a) and provided with sample container receptacles (64) for introducing sample containers (66) into the sample container receptacles (64). The vacuum centrifuge (10) also comprises a cover (16) disposed on the housing (14), closes the vacuum chamber (14a) in a vacuum-tight manner and, in the open state, frees the rotor (12) to enable loading and unloading of the rotor (12) with sample containers (66). Only one drive motor (52a) is provided for the rotor (12), disposed outside the vacuum chamber (14a) and coupled to the rotor (12) in the vacuum chamber (14a) to transmit the driving torque as part of a first drive mechanism.
