Definitions
- the invention relates to a centrifuge according to the type specified in the preamble of claim 1.
- Centrifuges with a removable rotor are already known, which have a device for axial
- a generic centrifuge is known from DE 10 2014 112 501 A1, which has a drive shaft and a rotor mounted on the drive shaft and axially removable in a removal direction.
- a quick-release fastener integrated in the rotor and the drive shaft is provided, by means of which the rotor can be fixed in relation to the drive shaft in the removal direction.
- the quick release includes an abutment in the drive shaft, in which the rotor with a
- Interlocking part engages, and at least one locking element which, when activated, fixes the rotor relative to the drive shaft.
- the locking element acts between the locking part of the rotor and the abutment of the drive shaft.
- the quick release has a power transmission element.
- the locking element is in via the force transmission element with an actuating element
- the locking element is elastic via its solid body joint pivoted. As a result, an axial force component must be generated when the rotor is introduced. In order to have to generate the lowest possible force, either the spring travel on the locking element must be increased, which entails a larger installation space, or the
- Material thickness of the locking element can be reduced, with the result that the clamping area is smaller. As a result, the holding force and operational safety of the quick-release fastener are reduced, especially taking into account manufacturing tolerances.
- One way to counteract this would be to thicken the material in the clamping area of the locking element. In practice, however, it has been shown that these areas can break in continuous operation.
- centrifuges Another problem with the known centrifuges is that rotors with a low mass cannot lock due to their own weight, since the axial force required to deflect the locking elements is too great, which can lead to incorrect operation.
- a centrifuge is known from DE 698 10 060 T2, in which, however, the locking elements can be pivoted about joints having vertically aligned pivot axes and the
- Locking mechanism is different. This construction has proven to be very stiff and prone to errors.
- the invention is therefore based on the object of developing a centrifuge in accordance with the type specified in the preamble of claim 1 in such a way that it is permanently reliable
- the invention is based on the finding that this object can be achieved simply if the locking element without elastic deformation from the locking division into one
- Unlocking position and vice versa can be pivoted and this is most easily implemented by a normal joint effective around a horizontal swivel axis, that is to say precisely no solid-state joint, in particular by a hinge joint.
- the pivot axis of the locking joint is therefore aligned perpendicular to a straight line parallel to the longitudinal axis of the drive shaft and the locking element with one around
- Swivel axis provided rotatable propeller shaft or bearing, the propeller shaft in a bearing engages or the bearing comprises a propeller shaft.
- the locking element is thus easily supported by a hinge bearing. In this way, the force to be applied can be reduced in a simple manner, since, compared to a solid-state joint, there is no longer any elastic deformation, but only the friction of the propeller shaft in the bearing has to be overcome.
- a pivoting movement about a horizontally oriented pivot axis makes pivoting considerably easier compared to a vertically oriented pivot axis. This makes it possible to connect the rotor to the drive shaft purely by gravity, without the need for additional force.
- the constructive design options increase.
- the drive shaft extends transversely to the longitudinal extent of the locking element and along the pivot axis of the locking element, about which the locking element is pivotally connected to the bearing.
- a relative movement takes place between the locking element with its cardan shaft and the bearing. In this way, an elastic deformation of the locking element is avoided in a simple manner.
- the bearing is preferably part of a force transmission element which is operatively connected to the actuating element.
- the bearing can be designed as a radial bearing in order to enable simple manufacture and to achieve high fatigue strength.
- the locking element perpendicular to its longitudinal extent has two cardan shaft areas extending laterally to the longitudinal extent, each of which is assigned to an area of the bearing. This prevents jamming due to one-sided mounting.
- the locking element has a locking area on one side with respect to the drive shaft area and a locking mass on the other side.
- the blocking mass is preferably heavier than the blocking area. It is thereby achieved that the locking mass is pressed outwards during operation of the centrifuge and at the same time the locking area of the locking element is pressed inwards and thus into the locking division. This increases the security of the quick-release fastener.
- the center of gravity of the locking element lies in the locking mass and there so outside the intersection of an axis along the longitudinal extent through the pivot axis that when Unlocking a torque acts on the locking area of the locking element in the direction of unlocking position.
- the blocking region of the blocking element is preferably curved and / or adapted in terms of shape to the abutment and / or locking bearing. This enables a compact connection that is small in size.
- the locking element on its side remote from the free end has a guide recess, in particular a U-shaped design. Especially when there are load changes in the centrifuge, loads on the bearing are reduced.
- the force transmission element preferably has a guide which engages in the recess.
- the blocking element is by powder injection molding, in particular metal powder injection molding - MIM -, by precision casting, by die casting
- Cold forming manufactured by plastic injection molding or by sintering. This allows both light and permanent load-resistant locking elements to be manufactured.
- each locking element is designed the same as the other and arranged at a uniform distance from the respectively adjacent locking element. This ensures that the quick-release fastener does not form an imbalance with the drive shaft and the rotor.
- the force transmission element is preferably spring-loaded in the direction of the locking position.
- the force transmission element can be designed as a cylindrical piston which is guided in a cylinder.
- the cylindrical piston can consist of several piston segments which are mounted so as to be movable relative to one another in relation to a cylinder axis.
- a spring is preferably provided which acts on the cylindrical piston.
- several springs are provided, one spring acting on a piston segment.
- manufacturing tolerances can be compensated and a flat contact of the locking element with the abutment and locking bearing can be guaranteed.
- the cylinder can be connected to the drive shaft so that the force transmission element is mounted on the drive shaft side. If the cylinder is connected to the rotor, it is
- Power transmission element mounted on the rotor side.
- a movement of the actuating element in the direction of the drive shaft toward or away from the drive shaft preferably takes place during the unlocking.

- the inner profile of the rotor hub 18 extends beyond the free end of the cylindrical part of the outer contour 16b of the adapter 16 and then merges into a central rotor area 22, which is connected to the rotor hub 18 in a rotationally fixed manner.
- the rotor central area 22 has a locking part 24 protruding into the adapter 16
- Outer contour the diameter of which, contrary to the removal direction 26, first increases to a widest point 24a and then decreases.
- the area of the outer contour in which the circumference decreases counter to the removal direction 26 forms a control surface 24b, the function of which will be explained later.
- the locking part 24 is spaced from the inner contour of the adapter 16.
- a bore 24c which is concentric with a drive axis 28 is made.
- the adapter 16 is provided centrally with a first cylindrical recess 30 and a second cylindrical recess 30 which immediately adjoins at the top and has a wider diameter, which results in an inner contour 32.
- the inner contour 32 is provided with a longer, higher section 32a, at the rotor-side end of which a shoulder 32b is connected. This shoulder 32b is in turn followed by a shorter, lower section 32c with an inner diameter that is widened compared to the longer section 32a.

- the abutment insert 44 has a bore 44a, which is dimensioned at the upper end so that the locking part 24 can pass with its widest point 24a.
- the bore 44a widens conically downward and forms an abutment surface 44b, the function of which will be explained later.
- the inner contour 32a, 32b, 32c of the adapter 16 forms, together with the abutment surface 44b of the abutment insert 44 and, when the rotor 14 is placed on the drive shaft 12, the outer contour of the locking part 24, the delimitation of a locking space in which the locking or

- the rotor-side part of the quick release fastener 20 is arranged essentially in the interior of the handle 48. It comprises an actuating pin 52, the length of which is greater than the axial extent of the handle 48 and which extends through the locking part 24 in the bore 24c on the shaft side and comes into contact with a bottom region 36a of the locking unit 36.
- the free end of the operating pin 52 has an operating button 52a. The unlocking takes place in the interaction of the handle 48 and the actuating button 52a.
- the actuation button 52a must be pressed, the handle 48 serving as a counter bearing for the user, then the rotor 14 can be removed, in particular, via the handle 48.

- the actuating pin 52 is pressed.
- the piston-shaped locking unit 36 with the bottom area of which the actuating pin 52 is in abutment on the shaft side, is displaced in the locking space against the action of the spring 42 against the removal direction 26, which runs parallel to the longitudinal axis of the drive shaft 12.

- the rotor 14 is brought into the locked position.
- the weight of the rotor 14 can be sufficient to introduce the rotor 14 and the locking position.
- the rotor may have to be pressed somewhat into the locking position.

- the locking elements 38 slide along the control surface 24b of the locking part 24 of the rotor 14, past the widest point 24a into their locking position between the
- FIG. 8 shows a section of a cross section along the central axis of the centrifuge 10 of FIG. 1 of the quick-release fastener 20 in the locked state.
- the actuating pin 52 is here in the position into which it is caused by the indirect one
- Actuation is brought automatically by the spring 42 when no pressure is exerted on it from the outside in the direction of the longitudinal axis of the drive shaft 12.
- the locking unit 36 and the locking elements 38 mounted on the locking unit 36 are, due to the action of the spring 42 and the lack of pressure exerted by the actuating pin 52 in the direction of the drive shaft 12, in the area of the locking space near the rotor.
