摘要： A centrifuge including a drive head attached to a rotation shaft and a rotor adapted to be removably mounted on the drive head in a rotational driving position and which is coupled thereto during rotation of the drive head. The centrifuge includes elements for axially locking the rotor to the drive head by applying to the rotor an axial retaining force that increases with the rotational speed of the drive head.

摘要： A centrifuge rotor locking apparatus includes a C-shaped annular member for a snap-fit engagement about a drive hub. The member comprises first and second contacting segments and a third non-contacting segment. Centrifugation causes the contacting segments to flex outwardly and come into contact with the interior wall of the drive hole of a mounted rotor. The unbalanced mass distribution of the annular member causes the member to tend to slide off the drive hub. This further separates the contacting segments, thus increasing the locking effect of the annular member/drive hub assembly to the rotor as the member is wedged in place between rotor and drive hub.

摘要： A light emitting element and a photo detector are disposed opposite each other in an outer housing of a centrifuge. When an angle rotor is mounted on a motor shaft, light emitted from the light emitting element is received by the photo detector without being intercepted by the angle rotor and, by the output of the photo detector, a permissible maximum revolving speed of the angle rotor is set high. When a swing rotor is mounted on the motor shaft, the light from the light emitting element is intercepted by the swing rotor, and hence is not received by the photo detector and, by the output of the photo detector, a permissible maximum revolving speed of the swing rotor is set low.

摘要： The invention relates to a centrifuge (10), having a drive shaft (12), a rotor (40) mounted on the drive shaft (12) so as to be detachable axially in a removal direction (66), a quick-action closure (54) integrated in the rotor (40) and the drive shaft (12), which closure can be used to secure the rotor (40) relative to the drive shaft (12) in a removal direction (66), an abutment (50, 52) in the drive shaft (12) which is engaged by a locking member (46) of the rotor (40), at least one blocking element (76), which—when activated—fixes the rotor (40) relative to the drive shaft (12) and which acts between the locking member (46) of the rotor (40) and the abutment (50, 52) of the drive shaft (12), which quick-action closure (54) includes a force-transmitting element (58, 72). The invention is characterized in that said blocking element (76) is actively connected to an actuating element (100, 100a) via the force-transmitting element (58, 72), that unlocking the quick-action closure (54) is effected by moving the actuating element (100, 100a), the force-transmitting element (58, 72) and the blocking element (76) relative to the locking member (46) in a direction in parallel to the drive shaft (12), and that during unlocking, the actuating element (100, 100a) is moved toward the drive shaft (12), and during locking, the force-transmitting element (58, 72) and the blocking element (76) on the one side and the locking member (46) on the other side are relatively moved toward each other.

摘要： A rotor body (3) for a laboratory centrifuge includes a rotor hub (14) which is inserted in a central opening and on the outside of which, at least one helically curve continuous groove (27) runs so as to form a transport facility for cooling air. The cooling air is effective in the direction of the axis (2) of the rotor hub (14) between the upper side (23) and the underside (22) of the rotor (1). In this manner, a cooling airstream which runs axially through the rotor (1) and undergoes direct thermal exchange with the rotor (1) and the mixtures to be treated in the laboratory centrifuge can be realized. No additional installation volume is required for this measure and equalization of the temperature of the rotor and the housing accommodating the rotor can be achieved.

摘要： The invention relates to a centrifuge with a drive head which can be connected with a drive, a rotor which can detachably be mounted on the drive head, at least one connection element with which the drive head can be connected in a torsion-proof manner with the rotor, and at least one coupling element which is attached to the drive head and is able to exert an axial force on the rotor in such a way that the rotor can be fixed axially, with the axial force increasing with the rising rotational speed of the drive head, with the coupling element on the rotor transmitting the axial force by means of a ramp surface which is inclined at an angle (α) relative to the horizontal line in a range of more than 0° to 15°. Secure locking of the rotor during standstill and high speeds can thus be achieved.
