Die Erfindung betrifft eine Spindelbank für eine Spinnmaschine mit einer an der Spindelbank angeordneten Spindeleinheit, die eine Spindel mit einem Aufnahmeabschnitt zur lösbaren Verbindung mit einer Spinnhülse sowie einen Elektromotor mit einem verdrehfest mit einem Spindelschaft der Spindel verbundenen Rotor aufweist. Die Erfindung betrifft außerdem eine Spinnmaschine mit einer Spindelbank.The invention relates to a spindle rail for a spinning machine with a spindle unit arranged on the spindle rail, which has a spindle with a receiving section for detachable connection to a spinning tube and an electric motor with a rotor connected non-rotatably to a spindle shaft of the spindle. The invention also relates to a spinning machine with a spindle rail.

Spinnmaschinen der eingangs genannten Art sind in vielfältigen Ausgestaltungen aus dem Stand der Technik bekannt. Diese weisen wenigstens eine Spindel mit jeweils einem Aufnahmeabschnitt als Träger für eine Spinnhülse auf. Der Antrieb der Spindel wird bevorzugt über einen Einzelantrieb bewirkt, der durch einen einen Rotor und einen Stator aufweisenden Elektromotor gebildet ist. Der verdrehfest mit dem Spindelschaft verbundene Rotor ist dabei mit einem zugehörigen Stator gekoppelt, welcher - ebenso wie die Spindellager - in einem geeigneten Lagergehäuse der Spindeleinheit verdrehfest angeordnet ist.Spinning machines of the type mentioned are known in a variety of configurations from the prior art. These have at least one spindle, each with a receiving section as a support for a spinning tube. The spindle is preferably driven via a single drive, which is formed by an electric motor having a rotor and a stator. The rotor, which is non-rotatably connected to the spindle shaft, is coupled to an associated stator, which—like the spindle bearing—is arranged non-rotatably in a suitable bearing housing of the spindle unit.

Die Verwendung von Einzelantrieben für die einzelnen Spindeln ist als Alternative zu einem Bandantrieb bekannt, wobei eine Vielzahl unterschiedlicher Ausführungsformen zu der Art und Anordnung der Spindeleinheiten an der diese aufnehmenden Spindelbanken existieren. Die EP 1 927 689 A1 offenbart ein solches Konzept, bei dem die Einzelantriebe jeweils ein Gehäuse aufweisen, in welchem sowohl die Lager als auch der Rotor und der Stator des Elektromotors angeordnet sind.The use of individual drives for the individual spindles is known as an alternative to a belt drive, with a large number of different embodiments relating to the type and arrangement of the spindle units on the spindle banks receiving them. the EP 1 927 689 A1 discloses such a concept in which the individual drives each have a housing in which both the bearings and the rotor and the stator of the electric motor are arranged.

Zur Montage der Spindeleinheiten an der Spindelbank ist es erforderlich, die einzelnen Spindeleinheiten über ihre Gehäuse ortsfest an der Spindelbank anzuordnen, wofür entsprechend ausgebildete Befestigungsmittel verwendet werden müssen. Neben den eigentlichen Lagergehäusen weisen solche Spindeleinheiten Außengehäuse auf, welche das Lagergehäuse umgeben. Insgesamt weisen die bekannten Spinnmaschinen daher aufgrund des bauraumintensiven Aufbaus der Spindeleinheiten einen hohen Platzbedarf auf, was entsprechend bauraumbeanspruchende Spindelbänke zur Folge hat. Die Vielzahl der Bauteile bekannter Spindeleinheiten hat ferner hohe Fertigungskosten zur Folge.In order to mount the spindle units on the spindle rail, it is necessary to position the individual spindle units in a stationary manner on the spindle rail via their housing, for which purpose appropriately designed fastening means must be used. In addition to the actual bearing housings, such spindle units have outer housings which surround the bearing housing. Overall, the known spinning machines therefore require a lot of space due to the space-intensive design of the spindle units, which results in spindle banks that take up a lot of space. The large number of components of known spindle units also results in high production costs.

Die DE 41 06 953 A1 und die DE 39 42 914 A1 offenbaren jeweils eine Spindelbank mit einer Aufnahmeöffnung, in der ein den Spindelschaft führendes Lager und ein Stator eines Elektromotors ohne ein separates Gehäuse positioniert sind.the DE 41 06 953 A1 and the DE 39 42 914 A1 each disclose a spindle rail with a receiving opening in which a bearing guiding the spindle shaft and a stator of an electric motor are positioned without a separate housing.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, die Auswechselbarkeit des führenden Lagers zu vereinfachen.Proceeding from this, the object of the invention is to simplify the exchangeability of the leading bearing.

Die Erfindung löst die Aufgabe durch eine Spindelbank mit den Merkmalen des Anspruchs 1 sowie eine Spinnmaschine mit einer Spindelbank mit den Merkmalen des Anspruchs 10. Vorteilhafte Weiterbildungen der Spindelbank sind in den abhängigen Ansprüchen angegeben.The invention solves the problem by a spindle rail with the features of claim 1 and a spinning machine with a spindle rail with the features of claim 10. Advantageous developments of the spindle rail are specified in the dependent claims.

Die Aufgabe wird durch eine Spindelbank zur Aufnahme einer Spindeleinheit für eine Spinnmaschine gelöst. Die Spindeleinheit weist eine Spindel mit einem Aufnahmeabschnitt zur lösbaren Verbindung mit einer Spinnhülse sowie einen Elektromotor mit einem verdrehfest mit einem Spindelschaft der Spindel verbundenen Rotor auf. Die Spindelbank weist eine Aufnahmeöffnung auf. Die Spindeleinheit weist kein zu der Spindelbank separates Gehäuse auf, sondern dieses wird durch die Aufnahmeöffnung der Spindelbank gebildet. Ein den Spindelschaft führendes Lager und ein Stator des Elektromotors sind in der Aufnahmeöffnung positioniert. Erfindungsgemäß ist das führende Lager in einer Flanscheinheit mit einem Durchgang für den zu lagernden Spindelschaft integriert. Die Flanscheinheit ist in die Aufnahmeöffnung auswechselbar eingesetzt und das führende Lager umfasst ein oberes Lager und ein unteres Lager umfasst, welche in Längsachsenrichtung des Spindelschafts auf einer gleichen Seite des Stators angeordnet sind.The task is solved by a spindle rail for accommodating a spindle unit for a spinning machine. The spindle unit has a spindle with a receiving section for detachable connection to a spinning tube and an electric motor with a rotor connected to a spindle shaft of the spindle in a rotationally fixed manner. The spindle rail has a receiving opening. The spindle unit does not have a housing that is separate from the spindle rail, but this is formed by the receiving opening of the spindle rail. A bearing guiding the spindle shaft and a stator of the electric motor are positioned in the receiving opening. According to the invention, the leading bearing is integrated in a flange unit with a passage for the spindle shaft to be supported. The flange unit is interchangeably fitted into the receiving hole, and the leading bearing includes an upper bearing and a lower bearing which are arranged on a same side of the stator in the longitudinal axis direction of the spindle shaft.

Gemäß der Erfindung weist die Spindelbank eine Aufnahmeöffnung auf, die zur Positionierung sowohl des Stators als auch des führenden Lagers ausgebildet ist. Unter einer Positionierung wird dabei im Rahmen der Erfindung eine zumindest verdrehfeste Verbindung des führenden Lagers sowie des Stators verstanden. Unter einem führenden Lager ist dabei ein solches Lager zu verstehen, welches geeignet ist, die Rotationsbewegung des Spindelschafts um ihre Längsachse kippfrei zu führen als auch zu lagern. Erfindungsgemäß weist das führende Lager ein erstes oberes Lager und ein zweites unteres Lager auf. Die Richtungsangabe "oben" bzw. "unten" ist dabei mit Blick auf den Aufnahmeabschnitt zur lösbaren Verbindung mit der Spinnhülse gewählt. Ein dem Aufnahmeabschnitt nahes Lager bildet im Sinne der vorliegenden Erfindung ein oberes Lager. Das weitere Lager, welches zu dem Aufnahmeabschnitt einen größeren Abstand als das obere Lager hat, bildet folglich das untere Lager. Erfindungsgemäß ist das obere und untere Lager auf einer gleichen Seite des Stators, insbesondere zueinander unmittelbar benachbart, angeordnet. Beispielsweise können das obere und untere Lager auf einer dem Aufnahmeabschnitt zugewandten Seite oder auf einer dem Aufnahmeabschnitt abgewandten Seite des Stators angeordnet sein. Dies erlaubt eine kompakte Ausgestaltung des führenden Lagers. Zur axialen Lagerung der Spindel kann in Abhängigkeit von der Ausgestaltung der Lagerung das führende Lager bzw. das obere und/oder untere Lager vorzugsweise ferner in eine oder beide axiale Richtungen der Spindel festgelegt sein. Im Folgenden ist mit dem Begriff "führendes Lager" synonym das führende Lager an sich als auch das obere und/oder untere Lager der bevorzugten Ausgestaltung des führenden Lagers zu verstehen.According to the invention, the spindle rail has a receiving opening designed for positioning both the stator and the leading bearing. Within the scope of the invention, positioning is understood to mean an at least non-rotatable connection of the leading bearing and of the stator. A leading bearing is to be understood as meaning a bearing that is suitable for guiding and supporting the rotational movement of the spindle shaft about its longitudinal axis without tilting. According to the invention, the leading bearing has a first upper bearing and a second lower bearing. The indication of the direction "up" or "down" is selected with a view to the receiving section for the detachable connection to the spinning tube. A bearing close to the receiving section forms an upper bearing in the sense of the present invention. The other bearing, which is at a greater distance from the receiving section than the upper bearing, consequently forms the lower bearing. According to the invention, the upper and lower bearings are on the same side of the stator, in particular with respect to one another immediately adjacent, arranged. For example, the upper and lower bearings can be arranged on a side of the stator facing away from the receiving section or on a side of the stator facing away from the receiving section. This allows a compact design of the leading bearing. Depending on the design of the bearing, the leading bearing or the upper and/or lower bearing can preferably also be fixed in one or both axial directions of the spindle for the axial bearing of the spindle. In the following, the term "leading bearing" is synonymous with the leading bearing itself and the upper and/or lower bearing of the preferred embodiment of the leading bearing.

Die erfindungsgemäße Ausgestaltung, wonach die Spindeleinheit kein zu der Spindelbank separates Gehäuse aufweist, sondern dieses durch die Aufnahmeöffnung der Spindelbank gebildet ist, führt zu einer kompakteren Bauweise der Spinnmaschine. Darüber hinaus lässt sich die Spinnmaschine, nachdem gegenüber bekannten Spindeleinheiten auf die kostenverursachenden Bauteile zur Bildung eines Gehäuses und notwendige Befestigungsmittel zur Befestigung der Gehäuse an der Spindelbank verzichtet werden kann, günstig herstellen. Auch lassen sich die Einzelantriebe aufgrund des Wegfalls eines bauraumbeanspruchenden Gehäuses kompakter ausführen, sodass die Spindeleinheit an der Spindelbank einen nur geringen Bauraum beansprucht.The configuration according to the invention, according to which the spindle unit does not have a housing that is separate from the spindle rail, but rather this is formed by the receiving opening of the spindle rail, leads to a more compact construction of the spinning machine. In addition, the spinning machine can be inexpensively manufactured since, compared to known spindle units, the costly components for forming a housing and the necessary fastening means for fastening the housing to the spindle rail can be dispensed with. The individual drives can also be made more compact due to the omission of a housing that takes up space, so that the spindle unit on the spindle rail takes up only a small amount of space.

Die Anordnung der Spindeleinheit in der gehäusebildenden Aufnahmeöffnung durch eine bestimmungsgemäße Positionierung des Stators und des führenden Lagers kann dabei in beliebiger Weise erfolgen. Das führende Lager ist erfindungsgemäß an einem Lagerträger angeordnet, der in oder an der Aufnahmeöffnung positionierbar ist. Der Lagerträger ist erfindungsgemäß eine Flanscheinheit, welche das führende Lager oder einen Bestandteil des führenden Lagers umfasst und in die Aufnahmeöffnung auswechselbar einsetzbar ist. Die Flanscheinheit weist dabei einen Durchgang für den zu lagernden Spindelschaft auf. Im Falle eines Defekts oder Verschleiß des führenden Lagers oder seines von der Flanscheinheit umfassten Bestandteils kann dieses bei auswechselbarer Befestigung auf einfache Weise ausgetauscht werden. Unter auswechselbar ist hierbei eine zerstörungsfreie Demontage des Lagerträgers, insbesondere der Flanscheinheit, zu verstehen. Die Flanscheinheit weist in bevorzugter Weise querschnittlich eine Zylinderform mit einem stirnseitigen Kragen auf, welcher zur Auflage auf der Spindelbank oder Anlage an der Spindelbank vorgesehen ist, wobei der zylinderförmige Abschnitt in die Aufnahmeöffnung einsetzbar ist. Dadurch kann auf einfache Weise eine exakte Positionierung des führenden Lagers innerhalb der Aufnahmeöffnung in Kombination mit einer Befestigung desselbigen an der Spindelbank erreicht werden.The spindle unit can be arranged in the housing-forming receiving opening by positioning the stator and the leading bearing as intended in any way. According to the invention, the leading bearing is arranged on a bearing carrier which can be positioned in or on the receiving opening. According to the invention, the bearing support is a flange unit which comprises the leading bearing or a component part of the leading bearing and can be inserted into the receiving opening in an exchangeable manner. The flange unit has a passage for the spindle shaft to be stored. In the event of a defect or wear of the leading bearing or its component part comprised by the flange unit, this can be easily replaced with an exchangeable attachment. In this context, interchangeable means non-destructive dismantling of the bearing support, in particular of the flange unit. The flange unit preferably has a cylindrical shape in cross section with a front collar which is provided for resting on the spindle rail or abutting against the spindle rail, the cylindrical section being insertable into the receiving opening. This enables the leading bearing to be positioned precisely within the receiving opening in a simple manner Combination with an attachment of the same can be achieved on the spindle bank.

Der Lagerträger kann alternativ dazu vorzugsweise ein die Aufnahmeöffnung querendes Element sein, welches ortsfest in der Aufnahmeöffnung derart angeordnet ist, dass sich das Lager an dem Lagerträger abstützen kann.As an alternative to this, the bearing support can preferably be an element which traverses the receiving opening and which is arranged stationarily in the receiving opening in such a way that the bearing can be supported on the bearing support.

Die Befestigung des Lagerträgers an der Spindelbank kann bedarfsgerecht aus den herkömmlichen Möglichkeiten der form-, kraft- und/oder stoffschlüssigen Befestigung ausgewählt sein. Eine bevorzugte spielfreie, als Übermaß- oder Übergangspassung ausgeführte Befestigung innerhalb der Aufnahmeöffnung kann bspw. mittels eines Presssitzes ausgeführt sein, welche sich im Besonderen für die Ausgestaltung des Lagerträgeres als querendes Element sowie für die Befestigung des Stators innerhalb der Aufnahmeöffnung eignet. Eine Montage kann dabei vorzugsweise in einer für den Fachmann bekannten Weise, beispielsweise durch die Ausnutzung thermischer Effekte beim Erhitzen oder Abkühlen der entsprechenden Komponenten erfolgen.The attachment of the bearing carrier to the spindle rail can be selected as required from the conventional possibilities of form-fitting, non-positive and/or material-locking attachment. A preferred backlash-free fastening within the receiving opening designed as an oversize or transition fit can be carried out, for example, by means of a press fit, which is particularly suitable for designing the bearing carrier as a crossing element and for fastening the stator within the receiving opening. In this case, assembly can preferably take place in a manner known to those skilled in the art, for example by utilizing thermal effects when heating or cooling the corresponding components.

Alternativ bevorzugt kann der Lagerträger, insbesondere die Flanscheinheit, zur Auswechselbarkeit desselbigen derart ausgestaltet sein, dass dieser mit einer Spielpassung montierbar ist.As an alternative, the bearing support, in particular the flange unit, can preferably be designed in such a way that it can be fitted with a clearance fit so that it can be replaced.

Die erfindungsgemäße Ausgestaltung der Spinnmaschine ermöglicht es insbesondere, auf aufwendige Mittel zur Befestigung der jeweiligen Einzelantriebe über deren Gehäuse an der Spindelbank zu verzichten. Neben der bereits erwähnten Bauteil- und Bauraumreduzierung bietet die erfindungsgemäße Spinnmaschine ferner den Vorteil, dass die Spindeleinheit gegenüber bekannten Spindeleinheiten ein geringeres Eigengewicht besitzt.The configuration of the spinning machine according to the invention makes it possible, in particular, to dispense with complex means for fastening the respective individual drives via their housing to the spindle rail. In addition to the already mentioned reduction in components and installation space, the spinning machine according to the invention also offers the advantage that the spindle unit has a lower weight than known spindle units.

Zur Erleichterung der Montage ist nach einer bevorzugten Weiterbildung der Erfindung eine Positionierungseinheit vorgesehen, welche den Stator und/oder das führende Lager in Längsachsenrichtung des Spindelschafts im Abstand zueinander festlegt. Die Positionierungseinheit bildet eine Montageeinheit, welche als Montagehilfe das führende Lager bzw. den Stator in Längsachsenrichtung des Spindelschafts zueinander festlegt. Die Positionierungseinheit bietet darüber hinaus jedoch keine Abstützung für das führende Lager oder den Stator, sondern erleichtert allein die Montage der Spindeleinheit in der Aufnahmeöffnung. Bei der Positionierungseinheit kann es sich beispielsweise um sich in Längsachsenrichtung des Spindelschafts erstreckende Stützstäbe handeln, die außenseitig mit dem führenden Lager oder mit dem das führende Lager tragenden Lagerträger bzw. dem Stator verbunden sind. Die Stützstäbe können beispielsweise, um eine flächige Anlage des führenden Lagers oder Lagerträger und/oder des Stators in der Aufnahmeöffnung zu gewährleisten, in entsprechend ausgebildeten, sich in Längsachsenrichtung des Spindelschafts erstreckenden Nuten in der Aufnahmeöffnung oder dem führenden Lager/Lagerträger und/oder dem Stator verlaufen. Die Verwendung von als Stützstäben ausgebildete Positionierungshilfen, beispielsweise drei oder vier im gleichmäßigen Abstand über den Umfang verteilt angeordneter Stützstäbe verbessern die axiale Position des führenden Lagers und des Stators zueinander und erleichtert die Montage der Spindeleinheit in der Aufnahmeöffnung.To facilitate assembly, according to a preferred development of the invention, a positioning unit is provided which fixes the stator and/or the leading bearing at a distance from one another in the direction of the longitudinal axis of the spindle shaft. The positioning unit forms an assembly unit which, as an assembly aid, fixes the leading bearing or the stator to one another in the direction of the longitudinal axis of the spindle shaft. In addition, however, the positioning unit does not offer any support for the leading bearing or the stator, but merely facilitates the assembly of the spindle unit in the receiving opening. The positioning unit can, for example, be support rods that extend in the direction of the longitudinal axis of the spindle shaft and are connected on the outside to the leading bearing or to the are connected to leading bearing supporting bearing bracket or the stator. The support rods can, for example, in order to ensure that the leading bearing or bearing carrier and/or the stator rests flat in the receiving opening, in correspondingly designed grooves in the receiving opening or in the leading bearing/bearing carrier and/or the stator, extending in the direction of the longitudinal axis of the spindle shaft get lost. The use of positioning aids in the form of support rods, for example three or four support rods arranged at equal intervals around the circumference, improves the axial position of the leading bearing and the stator relative to one another and facilitates assembly of the spindle unit in the receiving opening.

Nach einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass im Bereich zwischen dem führenden Lager und der Aufnahmeöffnung und/oder dem Stator und der Aufnahmeöffnung Dämpfungsmittel angeordnet sind. Bei dem Dämpfungsmittel kann es sich beispielsweise um federelastische Elemente, Elastomere, ein Fluid oder eine Kombination daraus handeln, welche sowohl in radialer als auch in axialer Richtung das führende Lager bzw. den Stator gegenüber der Aufnahmeöffnung abstützen. Insbesondere sind für die Dämpfung Elastomere oder Fluide oder eine Kombination daraus wegen einer damit einhergehenden größeren Energieumwandlungsfähigkeit und damit Dämpfung als die federelastischen Elemente bevorzugt. Die Dämpfungsmittel dienen dazu, die Präzisionsbewegungen der Spindel zu dämpfen. Die Dämpfungsmittel sind besonders bevorzugt ringförmig ausgebildet und besitzen ein bleibendes Rückstellverhalten, sodass sich das Spindelzentrum und die senkrechte Spindelstellung über die Zeit nicht verändert.According to a further preferred embodiment of the invention, it is provided that damping means are arranged in the region between the leading bearing and the receiving opening and/or between the stator and the receiving opening. The damping means can be, for example, spring-elastic elements, elastomers, a fluid or a combination thereof, which support the leading bearing or the stator in relation to the receiving opening both in the radial and in the axial direction. In particular, elastomers or fluids or a combination thereof are preferred for the damping because of the associated greater ability to convert energy and thus damping than the spring-elastic elements. The damping means serve to dampen the precision movements of the spindle. The damping means are particularly preferably ring-shaped and have a permanent restoring behavior, so that the spindle center and the vertical spindle position do not change over time.

Nach einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die vorgesehene Positionierungseinheit ein Dämpfungsmittel aufweist oder als kombinierte Positionierungs- und Dämpfungseinheit ausgebildet ist. Die Ausgestaltung der Positionierungseinheit mit Dämpfungsmitteln erlaubt es, auf eine Anordnung separater Dämpfungsmittel zu verzichten. Insbesondere die Ausgestaltung der Positionierungseinheit mit den Eigenschaften einer Dämpfungseinheit erlaubt es, auf zusätzliche Bauteile zu verzichten, wobei die kombinierte Positionierungs- und Dämpfungseinheit dabei sowohl die Möglichkeit bietet, das führende Lager und den Stator in axialer Richtung des Spindelschafts auszurichten als auch gegenüber der Aufnahmeöffnung elastisch abzustützen.According to a further preferred embodiment of the invention, it is provided that the positioning unit provided has a damping means or is designed as a combined positioning and damping unit. The configuration of the positioning unit with damping means makes it possible to dispense with an arrangement of separate damping means. In particular, the design of the positioning unit with the properties of a damping unit makes it possible to dispense with additional components, with the combined positioning and damping unit offering both the possibility of aligning the leading bearing and the stator in the axial direction of the spindle shaft and in relation to the receiving opening elastically to support.

Die Abstützung der Spindel in axialer Richtung kann grundsätzlich in beliebiger Weise erfolgen.In principle, the spindle can be supported in the axial direction in any desired manner.

So kann gemäß einer bevorzugten möglichen Ausgestaltung der Erfindung das führende Lager zur Aufnahme der axial auf die Spindel wirkenden Kräfte als Festlager ausgebildet sein. Zur Übertragung der Axialkräfte auf die Spindelbank ist nach einer bevorzugten Ausgestaltung der Erfindung vorgesehen, dass das führende Lager in Längsachsenrichtung des Spindelschafts an einer die Aufnahmeöffnung wenigstens teilweise überlappende Stützfläche anliegt. Bei der Stützfläche kann es sich beispielsweise um eine die Aufnahmeöffnung verschließende Abdeckung handeln, durch welche in bevorzugter Ausgestaltung der Spindelschaft hindurchragt bzw. welche den Spindelschaft einfasst. Die Stützfläche kann in besonders bevorzugter Weise durch den Lagerträger ausgebildet sein. Alternativ oder zusätzlich kann die Stützfläche in oder an der Aufnahmeöffnung angeordnet sein. Die Stützfläche kann vorzugsweise einstückig mit der Spindelbank ausgebildet, an der Spindelbank angeformt oder befestigt sein. Beispielsweise kann es sich bei der Stützfläche um einen die Aufnahmeöffnung begrenzenden Boden handeln.Thus, according to a preferred possible embodiment of the invention, the leading bearing for absorbing the forces acting axially on the spindle can be designed as a fixed bearing. In order to transmit the axial forces to the spindle rail, according to a preferred embodiment of the invention, the leading bearing rests against a support surface that at least partially overlaps the receiving opening in the direction of the longitudinal axis of the spindle shank. The support surface can be, for example, a cover that closes the receiving opening and through which the spindle shank protrudes or which encloses the spindle shank in a preferred embodiment. The support surface can be formed in a particularly preferred manner by the bearing bracket. Alternatively or additionally, the support surface can be arranged in or on the receiving opening. The support surface can preferably be formed in one piece with the spindle rail, molded onto or attached to the spindle rail. For example, the support surface can be a floor delimiting the receiving opening.

Die Abstützung ermöglicht in besonders einfacher Weise, axial auf die Spindel wirkende Kräfte zuverlässig auf die Spindelbank zu übertragen. Die Abstützung des führenden Lagers, bspw. an einer die Aufnahmeöffnung einseitig verschließende Abdeckung oder Boden ermöglicht es zudem, die Spindel in besonders einfacher Weise dämpfend in der Aufnahmeöffnung zu lagern, wobei hierzu zwischen dem führenden Lager und der Abdeckung bzw. dem Boden Dämpfungsmittel angeordnet sind.The support makes it possible in a particularly simple manner to reliably transmit forces acting axially on the spindle to the spindle rail. The support of the leading bearing, e.g. on a cover or base that closes the receiving opening on one side, also makes it possible to mount the spindle in a particularly simple manner in a damping manner in the receiving opening, damping means being arranged for this purpose between the leading bearing and the cover or the base .

Der Anschluss des Elektromotors an eine Versorgungs- und/oder Steuerungsleitung kann grundsätzlich in beliebiger Weise erfolgen. So können diese beispielsweise außenseitig an der Spindelbank zu einer Versorgungs- und/oder Steuerungseinheit geführt werden. Nach einer vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass die Spindelbank wenigstens eine in die Spindelbank integrierte, mit der Spindeleinheit verbundene Anschlussleitung aufweist, die bevorzugt mit einer an einer Außenseite, insbesondere einer Stirnseite der Spindelbank angeordneten Anschlussstelle verbunden sind.In principle, the electric motor can be connected to a supply and/or control line in any desired manner. For example, they can be routed to a supply and/or control unit on the outside of the spindle rail. According to an advantageous embodiment of the invention, however, it is provided that the spindle rail has at least one connecting line integrated into the spindle rail and connected to the spindle unit, which is preferably connected to a connection point arranged on an outside, in particular an end face of the spindle rail.

Gemäß dieser bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die wenigstens eine Anschlussleitung, beispielsweise eine Steuer- und Versorgungsleitung, innerhalb der Spindelbank derart verläuft, dass diese vor äußeren Einflüssen geschützt ist. In Abhängigkeit von der Anzahl der Spindeleinheiten verläuft die Versorgungsleitung dann zu einer außenseitig, insbesondere stirnseitig an der Spindelbank angeordneten Anschlussstelle. Diese insbesondere bevorzugte Ausführungsform ermöglicht es in besonders einfacher und kostengünstiger Weise die Spindelbank als Spindelbanksektion mit weiteren sich stirnseitig anschließenden Spindelbanksektionen zu verbinden, wobei deren gemeinsame Anschlussleitungen dann zu einer zentralen Versorgungs- und/oder Steuerungseinrichtung geführt werden. Die stirnseitig angeordneten Anschlussstellen bieten somit die Möglichkeit der einfachen Kopplung mehrerer Spindelbänke, die dann einzelne Spindelbanksektionen einer gemeinsamen Spindelbank bilden. Eine außenseitige Anordnung einer Anschlussstelle kann in bevorzugter Weise bedarfsgerecht ferner derart an der Spindelbank vorgesehen werden, dass entsprechende Stromabnehmer auf einfache Weise mit Strom versorgt werden können. Unter einer außenseitigen Anordnung sind sämtliche zugängliche Seitenwandungen der Spindelbank zu verstehen, welche die Spindelbank körperlich begrenzen. So bilden beispielsweise auch die innerhalb einer Aufnahmeöffnung zugänglichen Seitenwandungen der Spindelbank eine Außenseite für die Anordnung einer solchen Anschlussstelle ab.According to this preferred development of the invention, it is provided that the at least one connection line, for example a control and supply line, runs inside the spindle bank in such a way that it is protected from external influences. Depending on the number of spindle units, the supply line then runs to a connection point arranged on the outside, in particular on the face side, on the spindle rail. This particularly preferred embodiment makes it possible in a particularly simple and cost-effective manner to connect the spindle rail as a spindle rail section with other spindle rail sections adjoining at the front, with their common connection lines then being routed to a central supply and/or control device. The connection points arranged on the face side thus offer the possibility of a simple coupling of several spindle rails, which then form individual spindle rail sections of a common spindle rail. An external arrangement of a connection point can also be provided on the spindle rail in a preferred manner, as required, in such a way that corresponding current collectors can be supplied with electricity in a simple manner. An external arrangement means all accessible side walls of the spindle rail that physically delimit the spindle rail. For example, the side walls of the spindle rail that are accessible within a receiving opening also form an outside for the arrangement of such a connection point.

Gemäß einer bevorzugten Ausführungsform ist die Aufnahmeöffnung topfartig ausgebildet. Mit anderen Worten weist die Aufnahmeöffnung in einer Querschnittsebene, welche parallel zur Einsetzrichtung der Spindeleinheit verläuft, eine U-förmige oder ähnliche wie bspw. V-förmige Querschnittsgestalt auf. Dies erleichtert eine exakte Positionierung eines unteren Lagers, beispielsweise direkt auf dem Boden oder im Bereich des Bodens der topfartigen Aufnahmeöffnung.According to a preferred embodiment, the receiving opening is cup-shaped. In other words, in a cross-sectional plane which runs parallel to the direction of insertion of the spindle unit, the receiving opening has a U-shaped or similar, for example V-shaped, cross-sectional shape. This facilitates exact positioning of a lower bearing, for example directly on the floor or in the area of the floor of the pot-like receiving opening.

Alternativ dazu kann die Aufnahmeöffnung in dieser Querschnittsebene vorzugsweise eine zylinderförmige Querschnittsform aufweisen. Mit anderen Worten ist die Aufnahmeöffnung in Längsachsenrichtung der Zylinderform, welche parallel zu der Längsachsenrichtung des in der Aufnahmeöffnung aufzunehmenden Spindelschafts der Spindeleinheit bzw. der Einsetzrichtung ist, offen ausgestaltet und somit von außen aus beiden Längsachsenrichtungen zugänglich. Dadurch kann die Spindeleinheit bzw. einzelne Komponenten in der Aufnahmeöffnung vereinfacht eingesetzt und im Bedarfsfall gewartet, instandgesetzt oder ausgetauscht werden.As an alternative to this, the receiving opening can preferably have a cylindrical cross-sectional shape in this cross-sectional plane. In other words, the receiving opening is open in the longitudinal axis direction of the cylindrical shape, which is parallel to the longitudinal axis direction of the spindle shaft of the spindle unit to be received in the receiving opening or the insertion direction and is therefore accessible from the outside from both longitudinal axis directions. As a result, the spindle unit or individual components can be inserted in the receiving opening in a simplified manner and, if necessary, maintained, repaired or replaced.

In einer zu der Längsachsenrichtung quer, insbesondere senkrecht verlaufenden Querschnittsebene kann die Aufnahmeöffnung in bevorzugter Weise bedarfsgerecht ausgewählt jegliche zur Aufnahme der Spindeleinheit geeignete Querschnittsform wie eine Kreisform oder eine Vieleckform (Dreieck, Viereck, etc.) aufweisen.In a cross-sectional plane running transversely, in particular perpendicularly, to the direction of the longitudinal axis, the receiving opening can preferably have any cross-sectional shape suitable for receiving the spindle unit, such as a circular shape or a polygonal shape (triangle, square, etc.) as required.

Nach einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Spindelbank aus einem Aluminiumwerkstoff gebildet ist. Die Verwendung eines Aluminiumwerkstoffs erlaubt den Aufbau einer besonders gewichtsarmen Spinnmaschine, wobei die Verwendung eines Aluminiumwerkstoffs zudem die Einbringung der Aufnahmeöffnungen in die Spindelbank sowie der Spindeleinheit in die Aufnahmeöffnung erleichtert.According to a further preferred embodiment of the invention, it is provided that the spindle rail is formed from an aluminum material. The use of an aluminum material allows the construction of a particularly low-weight spinning machine, the use of an aluminum material also facilitating the introduction of the receiving openings into the spindle rail and the spindle unit into the receiving opening.

Alternativ kann die Spindelbank in bevorzugter Weise zur Reduzierung der Herstellkosten aus wenigstens einem gelaserten, gestanzten oder tiefgezogenen blechförmigen Material ausgebildet sein.Alternatively, the spindle rail can preferably be formed from at least one lasered, stamped or deep-drawn sheet metal material in order to reduce the production costs.

Die Aufnahmeöffnung ist nach einer bevorzugten Ausgestaltung der Erfindung durch eine Dichtungseinheit abgedichtet, wobei es sich bei einer Dichtungseinheit beispielsweise auch um einen die Aufnahmeöffnung verschließende Abdeckung oder aber auch um separate Bauteile handeln kann, welche an der die Aufnahmeöffnung verschließende Abdeckung angeordnet sind. Die Dichtungseinheit ist ausgebildet, Eintritt von Verschmutzung in die Aufnahmeöffnung, welche zu Störungen der Spindeleinheit führen können, zu verhindern.According to a preferred embodiment of the invention, the receiving opening is sealed by a sealing unit, wherein a sealing unit can also be, for example, a cover closing the receiving opening or separate components which are arranged on the cover closing the receiving opening. The sealing unit is designed to prevent contamination from entering the receiving opening, which could lead to malfunctions in the spindle unit.

Die Ausgestaltung der Aufnahmeöffnung der Spindelbank erlaubt es, die Spindeleinheit ohne Lager und/oder Außengehäuse auszuführen. Die Aufnahmeöffnung ist dabei derart ausgestaltet, dass das führende Lager direkt oder indirekt, bspw. über einen das führende Lager aufnehmenden Lagerträger, und der Stator sowohl verdrehfest als auch in geforderter Weise in axialer Richtung ortsfest in der Aufnahmeöffnung angeordnet sind. Die Möglichkeit zur gehäuselosen Anordnung der Spindeleinheit an der Spindelbank erlaubt es, die Spindelbank besonders kompakt und kostengünstig auszuführen, da auf die die Spindeleinheit umgebenden Gehäuse verzichtet werden kann.The design of the receiving opening of the spindle rail allows the spindle unit to be designed without a bearing and/or outer housing. The receiving opening is designed in such a way that the leading bearing is arranged directly or indirectly, e.g. via a bearing support receiving the leading bearing, and the stator is arranged in the receiving opening both torsionally and in the required manner stationary in the axial direction. The possibility of arranging the spindle unit on the spindle rail without a housing makes it possible to design the spindle rail in a particularly compact and cost-effective manner, since the housing surrounding the spindle unit can be dispensed with.

Die Erfindung betrifft außerdem eine Spinnmaschine mit einer an einer Spindelbank angeordneten Spindeleinheit, die eine Spindel mit einem Aufnahmeabschnitt zur lösbaren Verbindung mit einer Spinnhülse sowie einen Elektromotor mit einem verdrehfest mit einem Spindelschaft der Spindel verbundenen Rotor aufweist. Der Spindelschaft ist in einer Aufnahmeöffnung der Spindelbank gelagert, die Spindeleinheit weist kein zu der Spindelbank separates Gehäuse auf, sondern dieses wird durch die Aufnahmeöffnung der Spindelbank gebildet. Ein Stator des Elektromotors sowie ein den Spindelschaft führendes Lager sind in der Aufnahmeöffnung positioniert. Erfindungsgemäß ist das führende Lager in einer Flanscheinheit mit einem Durchgang für den zu lagernden Spindelschaft integriert, wobei die Flanscheinheit in die Aufnahmeöffnung auswechselbar eingesetzt ist und das führende Lager umfasst ein oberes Lager und ein unteres Lager, welche in Längsachsenrichtung des Spindelschafts auf einer gleichen Seite des Stators angeordnet sind.The invention also relates to a spinning machine with a spindle unit arranged on a spindle rail, which has a spindle with a receiving section for detachable connection to a spinning tube and an electric motor with a rotor connected non-rotatably to a spindle shaft of the spindle. The spindle shank is mounted in a receiving opening of the spindle rail, the spindle unit does not have a separate housing from the spindle rail, but this is formed by the receiving opening of the spindle rail. A stator of the electric motor and a bearing guiding the spindle shaft are positioned in the receiving opening. According to the invention, the leading bearing is in a single bore flange unit for the spindle shaft to be supported, the flange unit is interchangeably fitted into the receiving hole, and the leading bearing includes an upper bearing and a lower bearing which are arranged on a same side of the stator in the longitudinal axis direction of the spindle shaft.

Figur 1 zeigt in einer reinen schematischen Darstellung einen Querschnitt einer nicht erfindungsgemäßen Ausführungsform einer in einer Aufnahmeöffnung 16 einer Spindelbank 2 angeordneten Spindeleinheit 3. figure 1 shows in a purely schematic representation a cross section of an embodiment not according to the invention of a spindle unit 3 arranged in a receiving opening 16 of a spindle rail 2.

Eine Spindel 4 der Spindeleinheit 3 ist im Bereich ihres Spindeloberteils 14, welche eine herkömmliche Klemmkrone 23 umfasst, lösbar mit einer Spinnhülse 5 zur Ausbildung eines Kopses verbunden. Unterhalb des Spindeloberteils 14 ist ein Elektromotor 6 mit einem verdrehfest an einem Spindelschaft 7 angeordneten Rotor 8 und einem drehfest sowie in Aufnahmerichtung der Spindeleinheit 3 axialfest in der Aufnahmeöffnung 16 angeordneten Stator 9 angeordnet. Oberhalb des Rotors 8 und unterhalb des Spindeloberteils 14 ist ein als Wälzlager ausgebildetes oberes Lager 13 an einem in der Aufnahmeöffnung 16 abgestützten Lagerträger 18 angeordnet. Unterhalb des Rotors 8 ist ebenfalls ein Wälzlager 15 in einem Lagerträger 19 angeordnet, wobei der Lagerträger 19 stirnseitig an einem Boden 17 der Aufnahmeöffnung 16 und umlaufend an einer Innenwand der Aufnahmeöffnung 16 abgestützt ist. Unterhalb des Spindeloberteils 14 ist die Aufnahmeöffnung 16 durch eine Abdeckung 20 verschlossen, wobei die Abdeckung 20 an auf dem Lagerträger 18 aufliegenden Abstandshaltern 21 anliegt.A spindle 4 of the spindle unit 3 is in the region of its upper spindle part 14, which is a conventional one Clamping crown 23 includes detachably connected to a spinning tube 5 to form a cop. Below the upper spindle part 14 there is an electric motor 6 with a rotor 8 arranged in a rotationally fixed manner on a spindle shaft 7 and a stator 9 arranged in a rotationally fixed manner and axially fixed in the receiving opening 16 in the receiving direction of the spindle unit 3 . Above the rotor 8 and below the upper part 14 of the spindle, an upper bearing 13 designed as a roller bearing is arranged on a bearing carrier 18 supported in the receiving opening 16 . A roller bearing 15 is also arranged below the rotor 8 in a bearing bracket 19 , the bearing bracket 19 being supported at the end face on a base 17 of the receiving opening 16 and circumferentially on an inner wall of the receiving opening 16 . Below the upper part 14 of the spindle, the receiving opening 16 is closed by a cover 20 , the cover 20 resting against spacers 21 resting on the bearing carrier 18 .

In einer zweiten in Figur 2 rein schematisch dargestellten, nicht erfindungsgemäßen Ausführungsform der Spinnmaschine 1 ist die Spindeleinheit 3 entsprechend der in Figur 1 dargestellten Spindeleinheit 3 aufgebaut. Jedoch unterscheidet sich die Anordnung der Spindeleinheit 3 mit dem Elektromotor 6 und den Lagern 13, 15 in der Aufnahmeöffnung 16 von der in Figur 1 dargestellten Anordnung der Spindeleinheit 3. So ist im Bereich zwischen den Lagerträgern 18, 19 und der Aufnahmeöffnung 16 sowie dem Stator 9 und der Aufnahmeöffnung 16 ein dünnwandiges Dämpfungsmittel 22 angeordnet. Im Bereich des unteren Lagers 15 verläuft das Dämpfungsmittel 22 zwischen dem Boden 17 und der Innenwand der Aufnahmeöffnung 16. Im Bereich des Stators 9 sowie des oberen Lagers 18 verläuft das Dämpfungsmittel 22 im Bereich zwischen der Innenwand der Aufnahmeöffnung 16. Das Dämpfungsmittel 22 bewirkt eine Dämpfung der Rotationsbewegung der Spindel 4.In a second in figure 2 The embodiment of the spinning machine 1 shown purely schematically and not according to the invention is the spindle unit 3 according to the figure 1 spindle unit 3 shown constructed. However, the arrangement of the spindle unit 3 with the electric motor 6 and the bearings 13, 15 in the receiving opening 16 differs from that in figure 1 illustrated arrangement of the spindle unit 3. Thus, in the area between the bearing supports 18, 19 and the receiving opening 16 and the stator 9 and the receiving opening 16, a thin-walled damping means 22 is arranged. In the area of the lower bearing 15, the damping means 22 runs between the base 17 and the inner wall of the receiving opening 16. In the area of the stator 9 and the upper bearing 18, the damping means 22 runs in the area between the inner wall of the receiving opening 16. The damping means 22 causes damping the rotation of the spindle 4.

Figur 3 zeigt in schematischer Darstellung eine erfindungsgemäße Ausführungsform einer Spindeleinheit 3' in einer Aufnahmeöffnung 16 einer Spindelbank 2' nach einer weiteren Ausführungsform. Im Unterschied zu der Spindelbank 2 nach den Figuren 1 und 2 ist die Spindelbank 2' querschnittlich annähernd T-förmig mit einer innerhalb und entlang des vertikalen Stegs der T-Form verlaufenden Aufnahmeöffnung 16, welche an ihren längsseitigen Enden offen bzw. zugänglich ausgebildet ist. Des Weiteren unterscheidet sich die Spindeleinheit 3' von der mit den Figuren 1 und 2 gezeigten Spindeleinheiten 3 dadurch, dass das obere Lager 13 und das untere Lager 15 von einer Flanscheinheit 10 auf einer gleichen Seite des Stators 9 umfasst sind, wobei der Spindelschaft 7 wirkverbunden mit dem oberen Lager 13 und dem unteren Lager 15 durch die Flanscheinheit 10 hindurchragt. Die Flanscheinheit 10 weist einen Kragen 11 zur Auflage und Positionierung der Flanscheinheit 10 auf der Spindelbank 2' auf. Die Flanscheinheit 10 ist vorzugsweise mit einer spielbehafteten Passung versehen sein, wobei die Flanscheinheit 10 beispielsweise mittels einer nicht dargestellten Schraub- und/oder Rastverbindung an der Spindelbank festgelegt ist. Diese Art der Montage ist im Besonderen für die Auswechselbarkeit des von der Flanscheinheit 10 getragenen oberen 13 und unteren Lagers 15 vorteilhaft. Im Defektfall können diese ohne größeren Aufwand ersetzt werden. figure 3 shows a schematic representation of an embodiment according to the invention of a spindle unit 3' in a receiving opening 16 of a spindle rail 2' according to a further embodiment. In contrast to the spindle bank 2 after the figures 1 and 2 the spindle rail 2' is approximately T-shaped in cross-section with a receiving opening 16 running inside and along the vertical web of the T-shape, which opening is designed to be open or accessible at its longitudinal ends. Furthermore, the spindle unit 3 'differs from that with the figures 1 and 2 spindle units 3 shown in that the upper bearing 13 and the lower bearing 15 are surrounded by a flange unit 10 on the same side of the stator 9, the spindle shaft 7 being operatively connected to the upper bearing 13 and the lower bearing 15 and protruding through the flange unit 10. The flange unit 10 has a collar 11 for supporting and positioning the flange unit 10 on the spindle rail 2'. The flange unit 10 is preferably provided with a fit that is subject to play, the flange unit 10 being fixed to the spindle rail, for example by means of a screw and/or snap-in connection (not shown). This type of assembly is particularly advantageous for the interchangeability of the upper 13 and lower 15 bearings carried by the flange unit 10 . In the event of a defect, these can be replaced without much effort.

Figur 4 zeigt in schematischer Darstellung eine nicht erfindungsgemäßen Ausführungsform einer Spindeleinheit 3" in einer Aufnahmeöffnung 16 einer Spindelbank 2" nach einer weiteren Ausführungsform. Die Spindelbank 2" ist wie diejenige aus Figur 1 topfförmig ausgeformt, wobei im Boden 17 eine Ausnehmung zur Aufnahme der Dämpfungsmittel 22" vorgesehen ist. Die Dämpfungsmittel 22" umfassen ein in einem Dämpfungsfluid 22"a gelagertes Dämpfungselement 22"b, welches mit einem Ende des Spindelschafts 7 zur Dämpfung desselbigen zusammenwirkt. Der Stator 9 ist verdreh- und axialfest innerhalb der Aufnahmeöffnung 16 angeordnet. Die Anordnung des Stators 9 nach einem der Ausführungsformen kann beispielsweise mittels eines Presssitzes erfolgen. Der Rotor 8 ist verdrehfest an dem Spindelschaft 7 dem Stator 9 gegenüberliegend angeordnet. Die Spindeleinheit 3" weist wie diejenige aus Figur 3 eine als Lagergehäuse ausgebildete Flanscheinheit 10" mit einem oberen 13 und unteren Laer 15 auf, durch welche der Spindelschaft 7 drehbar gelagert hindurchragt. Im Unterschied zur Flanscheinheit 10 nach der Ausführungsform gemäß Figur 3 umfasst die Flanscheinheit 10" nach dieser Ausführungsform einen mit geringem Spiel behafteten Zentriersitz 12a, um die Flanscheinheit 10" im Bedarfsfall ohne größeren Aufwand auswechseln zu können. figure 4 shows a schematic representation of an embodiment of a spindle unit 3" not according to the invention in a receiving opening 16 of a spindle rail 2" according to a further embodiment. The spindle rail 2" is like the one from figure 1 pot-shaped, with a recess for receiving the damping means 22" being provided in the base 17. The damping means 22" comprise a damping element 22"b mounted in a damping fluid 22"a, which interacts with one end of the spindle shaft 7 for damping the same. The stator 9 is arranged inside the receiving opening 16 in a torsionally and axially fixed manner. The arrangement of the stator 9 according to one of the embodiments can take place, for example, by means of a press fit. The rotor 8 is arranged on the spindle shaft 7 opposite the stator 9 so that it cannot rotate. The spindle unit 3" shows the same as that figure 3 a flange unit 10" designed as a bearing housing with an upper 13 and a lower bearing 15, through which the spindle shaft 7 protrudes in a rotatably mounted manner. In contrast to the flange unit 10 according to the embodiment according to FIG figure 3 according to this embodiment, the flange unit 10" includes a centering seat 12a with little play, in order to be able to exchange the flange unit 10" without great effort if necessary.

Die Flanscheinheiten 10, 10" nach den Ausführungsformen der Figuren 3 und 4 fungieren als Lagerträger für das untere 15 und obere Lager 13 auf einer gleichen Seite des Stators 9. Die Flanscheinheit 10, 10" nach einem der Ausführungsformen ist besonders bevorzugt verdrehfest in der Aufnahmeöffnung angeordnet. Die Verdrehsicherung kann im Allgemeinen durch den vorstehend ausgeführten Presssitz nach der Ausführungsform gemäß Figur 3 erfolgen. Zusätzlich, sofern realisierbar, oder alternativ dazu, insbesondere im Falle eines wie mit der Ausführungsform nach Figur 4 vorgesehenen Zentriersitzes, kann die Verdrehsicherung durch andere, einem Fachmann allgemein bekannte Maßnahmen zur Verdrehsicherung realisiert sein. Insbesondere werden, jedoch nicht abschließend, und rein beispielhaft folgende Möglichkeiten aufgeführt: a) Befestigung des Kragens 11 an der Spindelbank 2" über nicht dargestellte Schraub- oder Rastverbindungen, b) querschnittlich dreieck- oder rechteckförmige Ausgestaltung des Zentriersitzes einhergehend mit einer dazu kongruenten Ausgestaltung des dazu korrespondierenden Abschnitts der Aufnahmeöffnung 16, c) Vorsehen eines Bajonettverschlusses beispielsweise ausgebildet durch den Zentriersitz 12a und den dazu korrespondierenden Abschnitt der Aufnahmeöffnung 16, d) Vorsehen eines Eingriffs und einer den Eingriff aufnehmenden Aufnahme, welche an dem Zentriersitz 12a und dem dazu korrespondieren Abschnitt der Aufnahmeöffnung 16 derart ausgebildet sind, dass im montierten Zustand eine Verdrehung der Flanscheinheit 10" relativ zu der Aufnahmeöffnung 16 unterbindbar ist, e) Ausbilden des Zentriersitzes 12a und des dazu korrespondierenden Abschnitts der Aufnahmeöffnung 16 als Schraubbefestigung über Vorsehen eines entsprechenden Gewindes und Gewindeganges. Bei der letztgenannten Alternative e) wäre es zudem möglich, auf den Kragen 11 zu verzichten. Die Flanscheinheit 10, 10" bildet demnach eine Gewindehülse umfassend das untere 15 und obere Lager 13 aus. Zur Vermeidung eines unbeabsichtigten Lösens dieser letztgenannten Alternative e) könnte zudem eine Sicherung vorgesehen sein. Diese Sicherung könnte beispielsweise ein Rastmittel sein, welches im Bereich der die Aufnahmeöffnung 16 einfassenden Oberfläche der Spindelbank 2, 2', 2" anordbar wäre.The flange units 10, 10 "according to the embodiments of Figures 3 and 4 act as a bearing support for the lower 15 and upper bearing 13 on the same side of the stator 9. The flange unit 10, 10" according to one of the embodiments is particularly preferably arranged in the receiving opening in a torsion-proof manner embodiment according to figure 3 take place. Additionally, if feasible, or alternatively, particularly in the case of an embodiment as per figure 4 provided centering seat, the anti-rotation device can be implemented by other anti-rotation measures generally known to a person skilled in the art. In particular, but not exhaustively, and purely by way of example, the following options are listed: a) attachment of the collar 11 to the spindle rail 2" via screw or snap-in connections, not shown, b) cross-sectionally triangular or rectangular configuration of the centering seat together with a congruent configuration of the section of the receiving opening 16 that corresponds thereto, c) provision of a bayonet catch, for example formed by the centering seat 12a and the section of the receiving opening 16 that corresponds thereto, d) provision of an engagement and a receptacle receiving the engagement, which the centering seat 12a and the corresponding section of the receiving opening 16 are designed in such a way that in the mounted state a rotation of the flange unit 10" relative to the receiving opening 16 can be prevented, e) forming the centering seat 12a and the corresponding section of the receiving opening 16 as a screw fastening Provision of a corresponding thread and thread pitch. In the case of the latter alternative e), it would also be possible to dispense with the collar 11. The flange unit 10, 10" accordingly forms a threaded sleeve comprising the lower 15 and upper bearing 13. In order to avoid an unintentional loosening of this latter alternative e), a safety device could also be provided. This safeguard could be, for example, a latching means which could be arranged in the area of the surface of the spindle rail 2, 2', 2'' enclosing the receiving opening 16.

Die beispielsweise aus einem Aluminiumwerkstoff hergestellte Spindelbank 2, 2', 2" ist in einer schematischen Darstellung in einer Draufsicht in Figur 5 dargestellt. Die benachbart zueinander angeordneten Aufnahmeöffnungen 16 der Spindelbank 2, 2', 2" dienen zur Aufnahme der Spindeleinheiten 3, 3', 3", die dann, wie auch aus den Figuren 6 und 7 ersichtlich, benachbart zueinander angeordnet sind. Die einzelnen Spindeleinheiten 3, 3', 3" können über eine gemeinsame, hier nicht dargestellte Versorgungs- und Antriebsleitung, welche bevorzugt in die Spindelbank 2, 2', 2" integriert oder an dieser angeordnet ist, mit einer geeigneten Steuerungseinheit verbunden werden.The spindle rail 2, 2', 2" made, for example, from an aluminum material is shown in a schematic plan view in FIG figure 5 shown. The adjacently arranged receiving openings 16 of the spindle rail 2, 2 ', 2 "are used to accommodate the spindle units 3, 3', 3", which then, as well as from the Figures 6 and 7 visible, are arranged adjacent to each other. The individual spindle units 3, 3′, 3″ can be connected to a suitable control unit via a common supply and drive line, not shown here, which is preferably integrated into the spindle rail 2, 2′, 2″ or arranged on it.

Nach einer alternativen, nicht dargestellten Ausführungsform ist die Spindelbank aus einem gelaserten, gestanzten oder tiefgezogenen blechförmigen Material ausgebildet. Eine solch ausgebildete Spindelbank ist insbesondere kostengünstig herstellbar.According to an alternative embodiment, not shown, the spindle rail is made of a lasered, stamped or deep-drawn sheet metal material. A spindle bank designed in this way can be produced particularly cost-effectively.
