摘要： A laboratory centrifuge includes elements (10) for the locking of a lid in a closed position, which locking elements (10) include at least one strike (11) and at least one bolt (12) mobile between a locking position and an unlocking position. These locking elements (10) also include operating elements (15) including a motor shaft (16) that is coupled to the bolt (12) through transmission elements (17). The transmission elements (17) include a crank (18), extending the motor shaft (16), which carries an actuating member (19) bearing on a contact surface (12c1, 12c2) formed on the bolt (12), so that the driving into eccentric rotation of the actuating member (19) about the motor axis of rotation (16′) causes its circulation and bearing along the contact surface (12c1, 12c2) and the rotational control of the bolt (12) between its locking and unlocking positions.

摘要： An assembly for transferring rotation from a centrifuge drive system to a centrifuge rotor includes a hub that is connected to the drive system for rotation about an axis. A sleeve member is attached to the hub in a position to support the centrifuge rotor. The sleeve member is formed of a material having a low coefficient of friction and is positioned to reduce the likelihood of rotor-to-hub lock. The resistance of the sleeve member to wear and to the absorption of foreign matter are also important in the selection of a material for forming the sleeve member. An acetal-based compound is preferred. By connecting the sleeve member to the hub such that the exterior surface of the sleeve member is raised relative to the surface of the hub, rotor-to-hub contact is reduced, thereby further reducing the risk that the rotor and the hub will become locked to one another.

摘要： Centrifuges are known which have a working head placed on a shaft driven by a motor, and in which a longitudinally slotted sleeve is disposed between the shaft and a central bore in the working head. This sleeve is expanded against the bore by a conical spreader driven by a threaded element screwed onto the end of the drive shaft. To create a tight and wobble-free coupling between the working head and the drive shaft of the centrifuge which will be secure even after long use and frequently changing torque, but which will assure easy release, the shaft has a tapered end and on this end, which reaches into the central bore of the working head, is seated the spreader, which is in the form of a bushing with a tapering bore, and the threaded element has on its outer circumference projections which engage indentations in the spreader.

摘要： The invention relates to a modified bayonet type mounting for use in a centrifuge. The mounting is characterized by having the trailing wall of the socket inclined at an obtuse angle, whereby relative rotation of the drive shaft and rotor during start-up causes the pin of the bayonet mounting to move deeper into the socket.

摘要： A flexible shaft transmitting the rotational motion of a motor shaft to a rotor adapter is protected from deformation by a shaft protector which connects the flexible shaft to the motor shaft. The shaft protector is concentric about and completely protects the flexible shaft as it extends from the motor shaft to the rotor adapter. The end of the flexible shaft connected to the rotor adapter and the rotor adapter itself are free to move within the lumen defined by the shaft protector. The shaft protector, however, prevents permanent deformation of the flexible shaft by preventing the flexible shaft from bending to a point at which permanent deformation would occur.In one important embodiment of the invention, a rotor adapter is provided with a plurality of grooves which prevent the rotor from jamming on to the rotor adapter.
