Definitions

  • the present invention relates to a connecting structure between a centrifuge rotor and a drive shaft of a centrifuge motor according to the preamble of claim 1.
  • Centrifuge rotors are used in centrifuges, particularly laboratory centrifuges, to separate the components of samples centrifuged therein by utilizing mass inertia. Increasingly higher rotation speeds are used to achieve high demixing rates.
  • Laboratory centrifuges are centrifuges whose centrifuge rotors preferably operate at at least 3,000, preferably at least 10,000, in particular at least 15,000 revolutions per minute and are usually placed on tables. In order to be able to place them on a work table, they have a form factor of less than 1 m x 1 m x 1 m, so their installation space is limited. The device depth is preferably limited to a maximum of 70 cm.
  • laboratory centrifuges are also known that are designed as floor-standing centrifuges, i.e. have a height in the range of 1 m to 1.5 m, so that they can be placed on the floor of a room.
  • centrifuges are used in the fields of medicine, pharmacy, biology and chemistry.
  • the samples to be centrifuged are stored in sample containers and these sample containers are rotated by the centrifuge rotor.
  • the centrifuge rotors are usually set in rotation by means of a vertical drive shaft that is driven by an electric motor.
  • the coupling between the centrifuge rotor and the drive shaft is usually made by means of the hub of the centrifuge rotor.
  • centrifuge rotors there are various centrifuge rotors that are used depending on the application.
  • the sample containers can contain the samples directly or the sample containers can have their own sample containers that contain the sample, so that a large number of samples can be centrifuged simultaneously in one sample container.
  • centrifuge rotors are known in the form of fixed-angle rotors and swing-out rotors and others.
  • the connecting structure between these centrifuge rotors and the drive shafts of the centrifuge motors which ensures the locking of the respective centrifuge rotor on the drive shaft during operation of the centrifuge, is usually designed universally, regardless of the type of centrifuge rotor, so that different types of centrifuge rotors can be used without any problems in the same centrifuge.
  • connection structures are usually designed in such a way that there is a screw connection between the centrifuge rotor and the shaft, which makes it possible to create a very secure and durable connection.
  • a key is required to operate the screw connection.
  • the disadvantage of this connection structure is that the key requires additional elements that can be misplaced, and one-handed operation is not possible.
  • the object of the present invention to at least partially overcome the disadvantages of the known constructions.
  • one-handed operation should be enabled, for which no additional tools are required.
  • the connecting structure should be designed in such a way that locking is always ensured, whereby jamming or blocking of locking elements cannot occur.
  • the connecting structure according to the invention is designed in such a way that an actuating means is provided on one of the drive shaft and centrifuge rotor elements, which makes the locking releasable, because this enables genuine one-handed operation and the actuating means also effectively prevent jamming or the like of the locking elements.
  • connection structure between a centrifuge rotor and a drive shaft of a centrifuge motor extending along a shaft axis, wherein a first locking element is arranged on one of the elements centrifuge rotor and drive shaft and a second locking element is arranged on the other of the elements centrifuge rotor and drive shaft, wherein the first locking element is in engagement with the second locking element in the locked state of the connection and is not in engagement in the unlocked state, is thus designed such that an actuating means is present on one of the elements centrifuge rotor and drive shaft, the actuation of which causes the first locking element to disengage from the second locking element, whereby the centrifuge rotor can be removed from the drive shaft.
  • the first locking element is a lever.
  • the term "lever arm” is understood to mean the part of the lever that locks with the second locking element.
  • the lever is mounted so that it can pivot around an axis. This makes the lever function particularly easy to implement.
  • the first connecting means has at least one bevel that serves as a locking aid, wherein the bevel preferably lies parallel to the longitudinal extension of the lever. This makes it particularly easy to lock the connecting structure because the first locking means does not represent an obstacle when the centrifuge rotor is attached to the drive shaft.
  • the first locking element is designed in such a way that it engages with the second locking element due to centrifugal force. This means that locking takes place automatically when the centrifuge is operating.
  • the first locking element is pre-tensioned in the direction of engagement with the second locking element.
  • the pre-tension can also serve as a pre-tension for the actuating means, although a separate pre-tension is preferably provided for the actuating means. If the pre-tension is used in addition to the centrifugal force, then the rotation of the centrifuge rotor reinforces the locking by the centrifugal force.
  • the first locking element is arranged on the centrifuge rotor. This allows the essential elements to be arranged in the centrifuge rotor, preferably its hub, which improves durability because the drive shaft itself does not have to have any moving parts for the connecting structure. It is then advantageously provided that there are at least two first locking elements, preferably three first locking elements. This makes the locking particularly secure.
  • the second locking element is a projection of the drive shaft, which the first locking element engages behind in the locked state. This makes the connecting structure particularly simple.
  • the actuating means has a contact surface for a counter-contact surface of the first locking element, wherein the contact surface has an inclined course in the actuating direction of the actuating means, at least in the locked state of the connecting structure, such that actuation of the actuating means causes pivoting of the first locking element.
  • the invention provides that the contact surface runs at an angle in the axial direction of the shaft axis. This means that, for example, levers arranged to pivot about an axis can be unlocked very easily.
  • the counter-contact surface will then ideally run straight in the direction of the shaft axis, but can also have an incline, which must, however, be dimensioned such that an unlocking force is exerted on the first locking element when the actuating means is moved in the actuating direction.
  • the actuating means is designed as a push button that is pre-tensioned against the actuating direction. This makes unlocking particularly easy and ergonomic.
  • the actuating means is located on the centrifuge rotor. This allows the drive shaft to be made compact. Alternatively, however, the actuating means could also be located on the drive shaft.
  • the connecting structure provides a snap-in connection, with the locking being carried out as part of a clip connection that is designed to be detachable. This makes the locking particularly secure and the user can easily understand the security that has been achieved by means of the snap-in sound.
  • the first connecting element would preferably be pre-tensioned in the direction of engagement with the second locking element.
  • the center of gravity of the first locking element could be arranged in such a way that the snap-in occurs automatically when the centrifuge rotor is placed on the drive shaft.
  • FIG. 1 to 6 the connecting structure 100 according to the invention is shown in a preferred embodiment in various views.
  • the connecting structure 100 between a centrifuge rotor 102 (only partially shown) and a drive shaft 104 (only partially shown) of a centrifuge motor (not shown) has three levers 106 as first locking elements 106, each of which is pivotably mounted about axes 108.
  • axes 108 are arranged in the hub 110 of the centrifuge rotor 102 such that the levers 106 extend concentrically around a receiving space 112 for the drive shaft 104, with an angular distance of 120° each.
  • the levers 106 each have a first lever arm 114 and a second lever arm 116, which are arranged opposite the axis 108, wherein a hook 118 pointing towards the shaft axis W is arranged on the first lever arm 114.
  • the receiving space 112 for the drive shaft 104 has an incorporated hexagon socket 120, which corresponds to a corresponding hexagon socket 122 of the drive shaft 104 and serves to transmit torque.
  • This hexagon socket 120 is preferably made of a harder material than the hub 110 and is fixed in this hub 110, for example screwed in or shrunk in.
  • the transmission of the torque from the drive shaft 104 to the centrifuge rotor 102 thus takes place via a positive connection 120, 122.
  • a positive connection 120, 122 As an alternative to the hexagonal design shown, another polygonal design, for example an octagonal design, could also exist, or the positive connection could be made by a spring-groove connection or a driving pin-groove connection or other positive connections that allow torque transmission.
  • the hub 110 has an inner cone 124 that corresponds to a conical section 126 of the drive shaft 104 and serves to ensure the perfectly aligned seat of the centrifuge rotor 102 on the drive shaft 104 and to provide a frictional connection.
  • This inner cone 124 merges into an inner cylinder 128 that is formed by a bearing block 130 that is screwed to the hub 110 and has arms 131 on which the axes 108 are arranged.
  • This bearing block 130 could also have preloading means, for example in the form of springs (not shown), that cause the first lever arms 114 with the hooks 118 to be preloaded toward the shaft axis W. However, in the embodiment shown, such separate preloading means are not provided.
  • the drive shaft 104 has a groove 132 with an upper projection 134 above the conical section 126, with a chamfer 136 extending above the upper projection 134. This projection 134 forms the second locking element.
  • the groove 132 has a peripheral design in the form of an external hexagon 137, which is aligned parallel to the external hexagon 122. As a result, each hook 118 is always parallel to a surface of the external hexagon 137 assigned to it.
  • the hooks 118 have bevels 138 that are oriented toward the inner cone 124. In the locked state, the hooks 118 engage in the groove 132 and engage behind the upper projection 134.
  • the hub 110 has a cylindrical cavity 140 above the bearing block 130, which is limited at the top by a cover-shaped closure element 142.
  • this closure element 142 which can be screwed 143 into the hub 110, for example, there is an opening 144 in which the actuating element 146 is received in a slidingly displaceable manner.
  • the actuating element 146 has a body 148 designed as a push button 148, which has a collar 150 in its lower section, which projects radially outward and rests against the closure element 142 when the actuating element 146 is not pressed in.
  • a projection 152 is arranged below the collar 150, wherein at the transition between the body 148 and the projection 152, opposite the collar 150, there is a section 154 with a conical inner contour, which acts as a contact surface that corresponds to a counter contact surface 156 of the lever 106.
  • the bearing block 130 has an elevation 158 through the outriggers 131 to form a recess 160 (cf. Fig. 2 ).
  • a spiral spring 162 is arranged in this recess 160 on the one hand and between the projection 152 and the outer circumference of the cavity 140 on the other hand and biases the actuating element 146 in an upward direction, i.e. opposite to the actuating direction B of the actuating element 146.
  • the spiral spring 162 thus provides an automatic return of the actuating element 146 from the actuated to the non-actuated state.
  • the opening 144 has a section 164 with a conical inclination, which corresponds to a conical counter-section 166 of the actuating element 146. This effectively prevents the actuating element 146 from tilting when it is moved by the spiral spring 162 against the actuating direction B.
  • connection structure 100 now works as follows: In in Fig. 1 In the state shown, the centrifuge rotor 102 is placed with its hub 110 onto the drive shaft 104 of the centrifuge motor. The hooks 118 with their bevels 138 come into contact with the bevel 136 of the drive shaft 104, whereby the first lever arm 114 is deflected outwards relative to the shaft axis W until the hooks 118 engage in the groove 132 and thereby engage behind the upper projection 134 (cf. Fig. 2 ). The two bevels 136, 138 thus provide a locking aid by preventing the hooks 118 from jamming or snagging on the drive shaft 104.
  • the center of mass M of the levers 106 is located outside and above in relation to the axes 108, whereby gravity causes the hooks 118 to engage in the groove 132.
  • the initial position of the levers 106 is limited by the conical inner surface 154 of the actuating element 146.
  • the second lever arms 116 cannot tilt outwards and prevent the centrifuge rotor 102 from being placed on the surface. Tilting inwards is also not a problem, since the drive shaft 104 pushes these levers 106 back into the correct position when the centrifuge rotor 102 is placed on the surface. However, tilting inwards could also be prevented by designing appropriate contact points in the bearing block 130 (not shown).
  • the push button 148 To release the lock, the push button 148 must be moved in the actuation direction B, i.e. downwards. This causes the contact surface 154 to contact the counter-contact surface 156, which runs parallel to the shaft axis W in the unswiveled state.
  • levers 106 pivotable about an axis 108 were used, levers pivotable about an axis and arranged on the drive shaft can also be used.
  • actuating element 146 does not necessarily have to be arranged on the hub 110 of the centrifuge rotor 102, it can also be arranged on the drive shaft.
  • Fig. 7 a laboratory centrifuge 200 is shown which is equipped with the connecting structure 10 according to the invention.
  • this laboratory centrifuge 200 is designed in a conventional manner and has a housing 202 with a control panel 206 arranged on its front side 204 and a lid 208 which is provided for closing the centrifuge container 210.
  • a fixed-angle rotor 12 is arranged in the centrifuge container 210 as a centrifuge rotor, which can be driven by the drive shaft of a centrifuge motor (neither shown).
  • the present invention provides a connecting structure 100 between centrifuge rotor 102 and drive shaft 104 of a laboratory centrifuge 200, by means of which one-hand operation is possible for which no additional tools are required.
  • the connecting structure 100 is designed in such a way that the locking 118, 132, 134 is always ensured, whereby jamming or blocking of locking elements 118, 132, 134 cannot occur.
