Description
Die Erfindung betrifft einen Offenend-Spinnrotor mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to an open-end spinning rotor with the Features of the preamble of claim 1.
Die meisten der zur Zeit in der Textilindustrie eingesetzten Offenend-Rotorspinnmaschinen weisen Spinnrotoren auf, die mit ihrem Rotorschaft in den Lagerzwickeln einer sogenannten Stützscheibenlagerung gelagert sind und dabei über einen maschinenlangen Tangentialriemen angetrieben werden.Most of those currently used in the textile industry Open-end rotor spinning machines have spinning rotors that work with their rotor shaft in the bearing gussets a so-called Support disc storage are stored and over a machine-long tangential belts are driven.
Diese Spinnrotoren, bei denen der Rotorschaft und die Rotortasse üblicherweise über einen Preßsitz nahezu unlösbar verbunden sind, können bei Bedarf, zum Beispiel bei Verschleiß, von vorne durch das geöffnete Rotorgehäuse ein- bzw. ausgebaut werden.These spinning rotors, in which the rotor shaft and the Rotor cup usually almost insoluble via a press fit connected, if necessary, for example at Wear, from the front through the open rotor housing or be expanded.
Des weiteren sind, beispielsweise durch die EP 0 972 868 A2, einzelmotorisch angetriebene Spinnrotoren bekannt, die mit ihrem Rotorschaft in einer Magnetlageranordnung abgestützt sind.Furthermore, for example by EP 0 972 868 A2, single motor driven spinning rotors known with their rotor shaft supported in a magnetic bearing arrangement are.
Die Magnetlageranordnung besteht dabei aus einer vorderen und einer hinteren Lagerstelle, wobei diese Lagerstellen ihrerseits jeweils über sich axial gegenüberstehende Permanentmagnetringe verfügen. Einer dieser Permanentmagnetringe ist dabei jeweils am Stator festgelegt, während der andere Permanentmagnetring mit dem Rotorschaft umläuft. The magnetic bearing arrangement consists of a front and a rear bearing, these bearings for their part, axially opposite each other Have permanent magnet rings. One of these Permanent magnet rings are fixed on the stator, while the other permanent magnet ring with the rotor shaft circulates.
Da der Ein-oder Ausbau derartig gelagerter Spinnrotoren einen
nicht unerheblichen Montageaufwand erfordert, ist bei diesen
Spinnrotoren die Rotortasse jeweils lösbar mit dem Rotorschaft
verbunden.
Das heißt, die Rotortasse kann bei Bedarf, zum Beispiel bei
einem Verschleiß oder bei einem Partiewechsel, nach dem Lösen
einer Schraubverbindung ausgebaut bzw. ausgewechselt werden,
ohne daß dabei auch der Rotorschaft mitausgebaut werden muß.Since the installation or removal of such spinning rotors requires a not inconsiderable amount of assembly work, the rotor cup in these spinning rotors is detachably connected to the rotor shaft.
This means that the rotor cup can be removed or replaced after loosening a screw connection, for example in the event of wear or when changing a lot, without the rotor shaft also having to be removed.
Die lösbare Koppelung von Rotorschaft und Rotortasse mittels
einer Schraubverbindung konnte allerdings nicht restlos
befriedigen.
Bei solchen Schraubverbindungen war beispielsweise,
insbesondere bei längerer Laufzeiten, nicht immer zu
gewährleisten, daß Rotortasse und Rotorschaft zu jedem
Zeitpunkt ausreichend fest verbunden sind.
Außerdem erwies es sich als relativ umständlich und
zeitaufwendig, die Rotortasse am Rotorschaft festzuschrauben,
während dieser in der Magnetlagerung abgestützt bleibt.However, the detachable coupling of the rotor shaft and rotor cup by means of a screw connection was not entirely satisfactory.
In the case of such screw connections, it was not always possible, for example, in particular in the case of longer running times, to ensure that the rotor cup and rotor shaft are sufficiently firmly connected at all times.
In addition, it turned out to be relatively cumbersome and time-consuming to screw the rotor cup onto the rotor shaft, while it remains supported in the magnetic bearing.
Neben der vorbeschriebenen Schraubverbindung sind aus der Patentliteratur noch zahlreiche weitere Ausführungsformen für Kupplungseinrichtungen bekannt, die ein lösbares Anschließen einer Rotortasse an einen Rotorschaft ermöglichen.In addition to the screw connection described above, the Patent literature still numerous other embodiments for Coupling devices known that connect releasably allow a rotor cup to a rotor shaft.
In der DE 38 15 182 A1 sind beispielsweise verschiedene
kraft- oder formschlüssig arbeitende Kupplungsvarianten
beschrieben, die ein einwandfreies und leicht lösbares
Festlegen der Rotortasse am Rotorschaft gewährleisten sollen.
Die einzelnen Kupplungsvarianten sind dabei allerdings insgesamt recht aufwendig konstruiert und damit relativ kostenintensiv.The individual coupling variants are, however overall constructed quite complex and therefore relative expensive.
Eine vergleichbare, in ihrem konstruktiven Aufbau deutlich
einfachere Kupplungseinrichtung ist in der EP 0 808 923 A1
beschrieben.
Diese bekannte Kupplungseinrichtung ist nach Art einer
Klipsverbindung aufgebaut, wobei ein Teil der Klipsverbindung
an der Rotortasse und das andere Teil am Rotorschaft
angeordnet ist.
Wenigstens ein Teil der Klipsverbindung wird dabei durch ein
elastisches Element beaufschlagt.A comparable coupling device, which is significantly simpler in terms of its construction, is described in EP 0 808 923 A1.
This known coupling device is constructed in the manner of a clip connection, part of the clip connection being arranged on the rotor cup and the other part on the rotor shaft.
At least part of the clip connection is acted upon by an elastic element.
Auch bei der Kupplungseinrichtung gemäß EP 0 808 923 A1 gestaltet sich ein Wechsel der Rotortasse, insbesondere, wenn der Rotorschaft während dieses Wechsels in der Lagereinrichtung eingebaut bleibt, zumindest umständlich. Außerdem ist bei dieser Kupplungseinrichtung, vor allem nach mehrmaligem An- und Abbau der Rotortasse, nicht immer gewährleistet, daß eine sichere Arretierung der Rotortasse am Rotorschaft auch bei hohen Drehzahlen des Spinnrotors stets gegeben ist.This also applies to the coupling device according to EP 0 808 923 A1 the rotor cup changes, especially if the rotor shaft during this change in the Storage facility remains installed, at least cumbersome. In addition, this coupling device, especially after repeated installation and removal of the rotor cup, not always ensures that the rotor cup is securely locked on Rotor shaft always at high speeds of the spinning rotor given is.
Weitere Kupplungseinrichtungen sind durch die DE 38 35 037 A1
oder die DE 196 18 027 A1 bekannt.Further coupling devices are described in
Die DE 38 35 037 A1 betrifft dabei eine mechanischhydraulische Spanneinrichtung, mit einer dünnwandige, aufweitbaren Hülse, die zwischen Rotorschaft und Rotortasse verspannbar ist. DE 38 35 037 A1 relates to a mechanical-hydraulic Clamping device, with a thin-walled, expandable sleeve between the rotor shaft and rotor cup is braced.
Die DE 196 18 027 A1 beschreibt eine Fliehkraftkupplung.
Das heißt, ein spezielles Kupplungselement weist
federkraftbeaufschlagte Kugeln auf, die während des Betriebes
des Spinnrotors infolge der Zentrifugalkraft nach außen
gedrückt werden und dabei die Rotortasse am Rotorschaft
arretieren.DE 196 18 027 A1 describes a centrifugal clutch.
This means that a special coupling element has spring-loaded balls that are pressed outwards as a result of the centrifugal force during operation of the spinning rotor and thereby lock the rotor cup on the rotor shaft.
Auch die vorbeschriebenen Kupplungseinrichtungen sind konstruktiv recht aufwendig und erfordern zudem aufgrund der hohen Rotordrehzahlen eine hohe Auswuchtgenauigkeit, was die Fertigung solcher Einrichtungen recht kostspielig macht.The coupling devices described above are also constructively quite complex and also require due to high rotor speeds a high balancing accuracy what the Manufacturing such devices makes them quite expensive.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die bekannten Kupplungseinrichtungen zum lösbaren Festlegen einer Rotortasse an einem Rotorschaft zu vereinfachen und dabei sicherzustellen, daß sowohl während des Spinnbetriebes eine sichere Haftung der Teile gegeben ist, als auch zu gewährleisten, daß die Rotortasse im Bedarfsfall leicht auswechselbar ist.Based on the aforementioned prior art, the Invention based on the object, the known Coupling devices for releasably fixing a rotor cup on a rotor shaft and simplify it ensure that both during spinning safe adhesion of the parts is given as well ensure that the rotor cup is light when needed is interchangeable.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gelöst, wie sie im Anspruch 1 beschrieben ist.This object is achieved by a device solved, as described in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of Dependent claims.
Die erfindungsgemäße Kupplungsvorrichtung ist nicht nur in ihrem konstruktiven Aufbau relativ einfach und daher recht kostengünstig in der Fertigung, sondern auch während des Betriebes zu jeder Zeit sehr sicher. The coupling device according to the invention is not only in their constructive structure relatively simple and therefore quite inexpensive to manufacture, but also during Operation very safe at all times.
Das heißt, die Magneteinrichtung der Kupplungsvorrichtung
sorgt automatisch dafür, daß die Spinntasse in axialer
Richtung stets mit maximaler Haltekraft am Rotorschaft
arretiert ist, während die mechanische Verdrehsicherung über
Formschluß jede rotatorische Relativbewegung zwischen den
beiden Bauteilen verhindert. Ein in einer Aufnahmehülse
angeordnetes Formschlußelement bildet in Verbindung mit einem
korrespondierenden Formschlußelement am Ansatz der Rotortasse
eine mechanische Verdrehsicherung.
Das Formschlußelement in der Aufnahmehülse ist dabei in
bevorzugter Ausführungsform als Innenmehrkant, vorzugsweise
als Innensechskant, ausgebildet.
Im Einbauzustand greift in diesen Innensechskant ein
entsprechend ausgebildeter, an der Rotortasse angeordneter
Außenmehrkant ein.This means that the magnetic device of the coupling device automatically ensures that the spinning cup is always locked in the axial direction with maximum holding force on the rotor shaft, while the mechanical anti-rotation lock prevents any rotational relative movement between the two components by positive locking. A form-locking element arranged in a receiving sleeve forms a mechanical anti-rotation device in connection with a corresponding form-locking element at the base of the rotor cup.
In a preferred embodiment, the form-locking element in the receiving sleeve is designed as an internal polygon, preferably as an internal hexagon.
In the installed state, a correspondingly designed outer polygon, which is arranged on the rotor cup, engages in this hexagon socket.
Wie im Anspruch 2 dargelegt, ist in bevorzugter
Ausführungsform vorgesehen, daß die Magneteinrichtung durch
einen am Rotorschaft mittels einer Aufnahmehülse festgelegten
Permanentmagnet und einen ferromagnetischen Ansatz an der
Rotortasse gebildet wird.
Eine solche Ausbildung hat insbesondere den Vorteil, daß der
relativ teure Teil der Magneteinrichtung, nämlich der
Permanentmagnet, auch dann weiter benutzt werden kann, wenn
die dem Verschleiß unterworfene Rotortasse aufgrund
entsprechende Abnutzung unbrauchbar geworden ist und
ausgetauscht werden muß.As set out in
Such a design has the particular advantage that the relatively expensive part of the magnetic device, namely the permanent magnet, can continue to be used even if the rotor cup subject to wear has become unusable due to corresponding wear and must be replaced.
In vorteilhafter Ausführungsform ist der Permanentmagnet
dabei, wie im Anspruch 3 beschrieben, in einer
rotationssymmetrischen Aufnahmehülse angeordnet, die, wie im
Anspruch 4 dargelegt, über einen Preßsitz mit dem Rotorschaft
verbunden ist. Der Rotorschaft kann dabei rohrförmig
ausgebildet sein, wobei die Aufnahmehülse mit einem
entsprechende Ansatz in den Rotorschaft greift. In an advantageous embodiment, the permanent magnet
thereby, as described in
Das Festlegen der rotationssymmetrischen Aufnahmehülse am Rotorschaft mittels eines Preßsitzes stellt dabei ein bewährtes Fügeverfahren dar, das auf einfache Weise nicht nur ein sicheres Festlegen der Aufnahmehülse und damit des Permanentmagneten am Rotorschaft ermöglicht, sondern auch sicher stellt, daß in den Rotorschaft keine Unwucht kommt.The setting of the rotationally symmetrical receiving sleeve on The rotor shaft adjusts by means of a press fit proven joining process that is not only simple a secure setting of the receiving sleeve and thus the Permits permanent magnets on the rotor shaft, but also ensures that there is no imbalance in the rotor shaft.
In vorteilhafter Ausführungsform weist die Aufnahmehülse des
weiteren, wie im Anspruch 5 dargelegt, eine zylindrische
Bohrung auf, die mit einem entsprechenden Führungsansatz an
der Rotortasse korrespondiert.In an advantageous embodiment, the receiving sleeve of the
further, as set out in
Eine solche Ausbildung ergibt eine nahezu spielfreie, leicht lösbare Verdrehsicherung, die außerdem kostengünstig zu fertigen ist.Such training results in an almost play-free, easy Detachable anti-rotation lock, which is also inexpensive is finished.
Weitere Einzelheiten der Erfindung sind einem nachfolgend anhand der Zeichnungen erläuterten Ausführungsbeispiel entnehmbar.Further details of the invention are as follows exemplary embodiment explained with reference to the drawings removable.
