- Radially front and rear recesses lying one behind the other in the radial direction are incorporated in the rotor, which is essentially designed as a horizontal disk, and are intended to enable the swivel cup to pivot into these recesses when the swivel cup swings out.
- the known swivel cups When swinging out, the known swivel cups rest with their bottom regions on a circumferential, radially outer flange of the rotor, the handle-like legs serving as swivel bearings, which engage in the associated recesses in the disk, no longer being supposed to have a load-transmitting effect.

- the legs are preferably inclined and are dimensioned (length, width and thickness, as well as angular position to the longitudinal axis of the sleeve of the swivel cup), that in a first preferred embodiment there is an approximate weight compensation for the swivel cup when the target speed of the rotor is reached.
- the length of the leg is chosen so that the free lower end of the leg approximately ends with the bottom region of the sleeve of the swivel cup, so that the swivel cup can be set up freely on an installation level and the leg thus serves as a supporting foot.
- the leg is bent, preferably an approximately Z-shaped shape is preferred, so that the free, bent end of the leg rests on certain stop surfaces of the disk-shaped rotor when the swivel cup swings out.
- the leg is bent so that in the rest position of the hanger, i.e. when the rotor is at a standstill, the free outer end of the leg bears against the rotor head so as to define the pivoting position of the swivel cup when the rotor is at a standstill.
- the rotor 1 according to Figures 1 and 2 consists essentially of a disc 2, which is preferably made of a high-strength, rustproof metal material, for. B. consists of a nickel-chromium alloy.

Abstract
Description
Die Erfindung betrifft einen Rotor für eine Schwenkbecherzentrifuge nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a rotor for a swivel cup centrifuge according to the preamble of patent claim 1.
Ein derartiger Rotor ist mit dem auf den gleichen Anmelder Zurückgehenden DE 89 03 511 U1 bekannt geworden. Bei diesem Rotor sind die Schwenkbecher als Probenröhrchen ausgebildet, so daß diese unmittelbar mit einer Probeflüssigkeit gefüllt sind und im übrigen aus Kunststoff bestehen. Es sind radial vordere und hintere in radialer Richtung hintereinander liegende Ausnehmungen in dem im wesentlichen als horizontale Scheibe ausgebildeten Rotor eingearbeitet, die ein Einschwenken des Schwenkbechers in diese Ausnehmungen beim Ausschwingen der Schwenkbecher ermöglichen sollen. Beim Ausschwingen legen sich die bekannten Schwenkbecher mit ihren Bodenbereichen an einem umlaufenden radial äußeren Flansch des Rotors an, wobei die als Schwenklager dienenden, henkelartigen Schenkel, die in zugeordnete Ausnehmungen der Scheibe eingreifen, nicht lastübertragend mehr wirken sollen. Es handelt sich also um Schwenklager, die lediglich der Lagensicherung und der Drehsicherung der ausschwingenden Schwenkbecher dienen und die mindestens bei Erreichen der Solldrehzahl keine weitere Zentrifugalkraft mehr übertragen sollen, weil diese über den Bodenbereich des Schwenkbechers auf den radial außen liegenden, umlaufenden Flansch des Rotors übertragen wird.Such a rotor has become known from DE 89 03 511 U1, which goes back to the same applicant. In this rotor, the swivel cups are designed as sample tubes so that they are filled directly with a sample liquid and, moreover, consist of plastic. Radially front and rear recesses lying one behind the other in the radial direction are incorporated in the rotor, which is essentially designed as a horizontal disk, and are intended to enable the swivel cup to pivot into these recesses when the swivel cup swings out. When swinging out, the known swivel cups rest with their bottom regions on a circumferential, radially outer flange of the rotor, the handle-like legs serving as swivel bearings, which engage in the associated recesses in the disk, no longer being supposed to have a load-transmitting effect. These are swivel bearings that only serve to secure the position and the rotation of the swinging out swivel cups and that should no longer transmit any centrifugal force at least when the setpoint speed is reached, because they transfer to the radially outer circumferential flange of the rotor via the bottom area of the swivel cup becomes.
Mit dem bekannten Rotor bestand also der Vorteil, daß man relativ kostengünstige Probengefäße verwenden konnte, die mit ihren henkelartigen, freien Schenkeln ohne weitere Hilfsmittel in den Rotor eingehängt werden konnten.The known rotor therefore had the advantage that relatively inexpensive sample vessels could be used, which could be hooked into the rotor with their handle-like, free legs without any additional aids.
Wegen der Notwendigkeit der Lastübertragung der auf die Schwenkbecher wirkenden Zentrifugalkraft über den radial außen liegenden Flansch des Rotors ergab sich jedoch ein erhöhter Herstellungsaufwand für den Rotor.Because of the necessity of the load transmission of the centrifugal force acting on the swivel cups via the radially outer flange of the rotor, however, there was an increased manufacturing outlay for the rotor.
Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Rotor der eingangs genannten Art so weiterzubilden, daß der Rotor selbst einfach ausgebildet sein kann und trotzdem hohe Zentrifugalkräfte von den Schwenkbechern auf den Rotor übertragbar sind.The invention is therefore based on the object of developing a rotor of the type mentioned in such a way that the rotor itself can be of simple construction and nevertheless high centrifugal forces can be transmitted from the swivel cups to the rotor.
Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruches 1 gekennzeichnet.To achieve the object, the invention is characterized by the technical teaching of claim 1.
Wesentliches Merkmal der Erfindung ist, daß nun der Rotor im wesentlichen als Scheibe ausgebildet ist, die eine Reihe in Umfangsrichtung verteilt angeordneter Schlitze trägt. Es entfällt nun die Notwendigkeit, am Außenumfang des Rotors einen lastübertragenden, radialen, abgekröpften Flansch vorzusehen, welcher die Zentrifugalkraft der Schwenkbecher aufnimmt, wie dies bei dem DE 89 03 511 U1 gefordert war.An essential feature of the invention is that the rotor is now essentially in the form of a disk which bears a series of slots distributed in the circumferential direction. There is now no need to provide a load-transmitting, radial, cranked flange on the outer circumference of the rotor, which absorbs the centrifugal force of the swivel cup, as was required in DE 89 03 511 U1.
Erfindungsgemäß wird die Zentrifugalkraft, welche auf die Schwenkbecher wird, direkt von den Schwenkbechern auf das jedem Schwenkbecher zugeordnete Trägerteil übertragen, welches Trägerteil im wesentlichen aus einem ringförmigen Metallteil besteht, welches in der Hülse des Schwenkbechers eingebettet ist, wobei an diesem Ringteil - bevorzugt werkstoffeinstückig - mindestens ein Schenkel angeformt ist, mit dem dieses Trägerteil durch den Schlitz im Rotor hindurchgreift und dort schwenkbar gelagert ist.According to the invention, the centrifugal force which is exerted on the swivel cups is transmitted directly from the swivel cups to the support part assigned to each swivel cup, which support part essentially consists of an annular metal part which is embedded in the sleeve of the swivel cup, with this ring part - preferably made of one piece of material - at least one leg is formed, with which this carrier part engages through the slot in the rotor and is pivotably mounted there.
Damit ergibt sich ein extrem einfacher Aufbau des Rotors, weil lediglich eine Scheibe mit Schlitzen vorgesehen werden muß, durch welche die einzelnen Schenkel der Trägerteile der jeweiligen Schwenkbecher hindurchgreifen.This results in an extremely simple construction of the rotor, because only a disk with slots has to be provided, through which the individual legs of the carrier parts of the respective swivel cups pass.
Die genannten Schenkel greifen also kraftschlüssig und lastübertragend in die zugeordneten Schlitze der Scheibe des Rotors ein, während dies bei der älteren Druckschrift vermieden werden sollte.The legs mentioned thus engage in a force-locking and load-transmitting manner in the associated slots in the rotor disk, while this should be avoided in the older publication.
Die Schenkel sind bevorzugt schräg gestellt und sind so dimensioniert (Länge, Breite und Dicke, sowie Winkelstellung zur Längsachse der Hülse des Schwenkbechers), daß sich in einem ersten bevorzugten Ausführungsbeispiel ein annähernder Gewichtsausgleich für den Schwenkbecher bei Erreichen der Solldrehzahl des Rotors ergibt. Das heißt, die vom Schenkel ausgeübte Zentrifugalkraft und die von der Hülse des Schwenkbechers auf den Schlitz des Rotors ausgeübte Zentrifugalkraft soll bei Erreichen der Solldrehzahl der Zentrifuge etwa gleich sein, so daß sich der Schwenkbecher in einer horizontalen Schwenklage einstellt.The legs are preferably inclined and are dimensioned (length, width and thickness, as well as angular position to the longitudinal axis of the sleeve of the swivel cup), that in a first preferred embodiment there is an approximate weight compensation for the swivel cup when the target speed of the rotor is reached. This means that the centrifugal force exerted by the leg and the centrifugal force exerted by the sleeve of the swivel cup on the slot of the rotor should be approximately the same when the desired speed of the centrifuge is reached, so that the swivel cup is set in a horizontal swivel position.
In einem zweiten Ausführungsbeispiel ist es vorgesehen, daß ein beabsichtigtes Ungleichgewicht zwischen der vom Schenkel auf den Schlitz ausgeübten Zentrifugalkraft im Vergleich zu der von der Hülse auf den Schlitz ausgeübten Zentrifugalkraft ergibt, so daß eine beabsichtigte Schrägstellung des gesamten Schwenkbechers bei Erreichen der Solldrehzahl des Rotors gegeben ist.In a second embodiment it is provided that there is an intended imbalance between the centrifugal force exerted by the leg on the slot in comparison with the centrifugal force exerted by the sleeve on the slot, so that there is an intended inclination of the entire swivel cup when the target speed of the rotor is reached is.
In einem Ausführungsbeispiel ist die Länge des Schenkels so gewählt, daß das freie untere Ende des Schenkels etwa mit dem Bodenbereich der Hülse des Schwenkbechers abschließt, so daß der Schwenkbecher frei auf einer Aufstellebene aufgestellt werden kann und der Schenkel somit als Stützfuß dient.In one embodiment, the length of the leg is chosen so that the free lower end of the leg approximately ends with the bottom region of the sleeve of the swivel cup, so that the swivel cup can be set up freely on an installation level and the leg thus serves as a supporting foot.
In einer anderen Ausgestaltung ist es vorgesehen, daß der Schenkel abgekröpft ausgebildet ist, wobei bevorzugt eine etwa Z-förmige Formgebung bevorzugt wird, so daß sich das freie, abgekröpfte Ende des Schenkels bei ausschwingendem Schwenkbecher an bestimmten Anschlagflächen des scheibenförmigen Rotors anlegt.In another embodiment it is provided that the leg is bent, preferably an approximately Z-shaped shape is preferred, so that the free, bent end of the leg rests on certain stop surfaces of the disk-shaped rotor when the swivel cup swings out.
Damit kann die Winkellage des ausschwingenden Schwenkbechers begrenzt werden.This allows the angular position of the swinging swing cup to be limited.
In einer anderen Ausgestaltung der Erfindung ist es vorgesehen, daß der Schenkel so abgekröpft ist, daß sich in der Ruhelage des Gehänges, d.h. bei stillstehendem Rotor, sich das freie äußere Ende des Schenkels an dem Rotorkopf anlegt, um so die Schwenkstellung des Schwenkbechers bei stillstehendem Rotor zu definieren.In another embodiment of the invention it is provided that the leg is bent so that in the rest position of the hanger, i.e. when the rotor is at a standstill, the free outer end of the leg bears against the rotor head so as to define the pivoting position of the swivel cup when the rotor is at a standstill.

Der Rotor 1 nach Figur 1 und 2 besteht im wesentlichen aus einer Scheibe 2, die bevorzugt aus einem hochfesten, nicht rostenden Metallmaterial, z. B. einer Nickel-Chrom-Legierung besteht.The rotor 1 according to Figures 1 and 2 consists essentially of a

In einem bevorzugten Ausführungsbeispiel gemäß den Figuren 5 bis 7 ist das freie Ende des Schenkels 12 so lang gewählt, daß es etwa eine Linie 17 mit dem Bodenbereich der Hülse 7 bildet, wobei am Bodenbereich der Hülse noch zusätzlich eine Rippe 16 angeformt sein kann. Auf diese Weise dient der Schenkel 12 als Stützfuß für den Schwenkbecher 6, der damit frei auf einer Aufstellfläche aufgestellt werden kann.In a preferred exemplary embodiment according to FIGS. 5 to 7, the free end of the

Bei Erreichen der Nenndrehzahl des Rotors verschwenken die Schwenkbecher 6 nach außen, wie dies in Figur 1,2 auf der linken Seite dargestellt ist. Hierbei dienen die Kanten 10 der Schlitze 9 als Schwenklager und das Ausschwingen erfolgt im Übergangsbereich zwischen dem geraden Teil 13 und dem nach unten abgebogenen Schenkel 12 des Trägerteils 11.When the nominal speed of the rotor is reached, the swivel cups 6 pivot outwards, as shown in FIG. 1, 2 on the left side. Here, the
Bei der Erfindung ist demzufolge wichtig, daß das Trägerteil 11 lastübertragend die Zentrifugalkraft auf den Schlitz 9 über die Kante 10 auf die Scheibe 2 überträgt. Der Rotor kann somit einfachst ausgebildet sein und es bedarf keiner aufwendigen Anlageflächen am Rotor, um Zentrifugalkräfte aufzunehmen.It is therefore important in the invention that the
