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 at the outset are known in a variety of configurations from the prior art.

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.To mount the spindle units on the spindle bench, it is necessary to arrange the individual spindle units in a stationary manner on the spindle bench via their housing, for which purpose appropriately trained fastening means must be used.

Overall, the known spinning machines therefore require a large amount of space due to the space-intensive construction of the spindle units, which consequently results in spindle banks which take up space. The large number of components of known spindle units also results in high manufacturing costs.

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. Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung können das obere und untere Lager auf einer gleichen Seite des Stators, insbesondere zueinander unmittelbar benachbart, angeordnet sein. 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. Alternativ dazu können das obere und untere Lager auf unterschiedlichen Seiten des Stators angeordnet sein. Der dadurch bedingte vergrößerte Lagerabstand zwischen dem oberen und unteren Lager wirkt sich positiv auf die Lagerstabilität des zu lagernden Spindelschaftes aus. 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 bank has a receiving opening which is designed to position both the stator and the leading bearing. In the context of the invention, positioning is understood to mean an at least torsion-resistant connection of the leading bearing and the stator. A leading bearing is to be understood as such a bearing which is suitable for guiding the rotational movement of the spindle shaft about its longitudinal axis without tilting and also for storing it. The leading bearing preferably has a first upper bearing and a second lower bearing. The direction "above" or "below" is selected with a view to the receiving section for releasable connection to the spinning sleeve. A bearing near the receiving section forms an upper bearing in the sense of the present invention. The further bearing, which is at a greater distance from the receiving section than the upper bearing, consequently forms the lower bearing. According to a preferred embodiment of the present invention, the upper and lower bearings can be arranged on the same side of the stator, in particular directly adjacent to one another. For example, the upper and lower bearings can be arranged on a side of the stator facing the receiving section or on a side of the stator facing away from the receiving section. This allows a compact design of the leading warehouse. Alternatively, the upper and lower bearings can be arranged on different sides of the stator. The resulting increased bearing distance between the upper and lower bearings has a positive effect on the storage stability of the spindle shaft to be supported. For the axial mounting of the spindle, depending on the design of the mounting, the leading bearing or the upper and / or lower bearing can preferably also be fixed in one or both axial directions of the spindle. In the following, the term "leading bearing" is to be understood synonymously as the leading bearing itself and also 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 embodiment according to the invention, according to which the spindle unit does not have a housing separate from the spindle bench, but rather is formed by the receiving opening of the spindle bench, leads to a more compact construction of the spinning machine. In addition, the spinning machine can be produced inexpensively, since, compared to known spindle units, the cost-causing components for forming a housing and the necessary fastening means for fastening the housing to the spindle bench can be dispensed with. The individual drives can also be made more compact due to the omission of a housing which takes up space, so that the spindle unit on the spindle bench takes up only a small 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 kann grundsätzlich direkt in Kontakt mit der Aufnahmeöffnung und/oder einen die Aufnahmeöffnung begrenzenden Abschnitt stehen oder aber bspw. an einem Lagerträger angeordnet sein, der in oder an der Aufnahmeöffnung positionierbar ist. Ein solcher Lagerträger kann beispielsweise eine Flanscheinheit sein, welche das führende Lager oder einen Bestandteil des führenden Lagers umfasst und in die Aufnahmeöffnung, insbesondere 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 desired manner. The leading bearing can in principle be in direct contact with the receiving opening and / or a section delimiting the receiving opening or, for example, can be arranged on a bearing bracket which can be positioned in or on the receiving opening. Such a bearing bracket can be, for example, a flange unit, which comprises the leading bearing or a component of the leading bearing and can be inserted, in particular exchangeably, into the receiving opening. The flange unit has a passage for the spindle shaft to be supported. In the event of a defect or wear of the leading bearing or of its component part included in the flange unit, this can be exchanged in a simple manner with replaceable fastening. Interchangeable here is to be understood as non-destructive dismantling of the bearing bracket, in particular the flange unit. The flange unit preferably has a cross-sectionally cylindrical shape with an end collar, which is provided for resting on the spindle bench or against the spindle bench, the cylindrical section being insertable into the receiving opening. As a result, an exact positioning of the leading bearing within the receiving opening in combination with an attachment thereof to the spindle bench can be achieved in a simple manner.
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 bracket can preferably be an element that crosses the receiving opening and is arranged in a stationary manner in the receiving opening such that the bearing can be supported on the bearing bracket.
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 mounting of the bearing bracket on the spindle bench can be done as required from the conventional Possibilities of positive, non-positive and / or material fastening can be selected. A preferred backlash-free fastening within the receiving opening, which is designed as an oversize or transition fit, can be carried out, for example, by means of a press fit, which is particularly suitable for the configuration of the bearing bracket as a crossing element and for fastening the stator within the receiving opening. Assembly can preferably be carried out 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.Alternatively, the bearing bracket, in particular the flange unit, can be designed so that it can be replaced so that it can be fitted with a clearance fit.
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 design 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 on the spindle bench. In addition to the reduction in component and installation space already mentioned, 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, a positioning unit is provided according to a preferred development of the invention which fixes the stator and / or the leading bearing in the longitudinal axis direction of the spindle shaft at a distance from one another. The positioning unit forms an assembly unit which, as an assembly aid, fixes the leading bearing or the stator in the longitudinal axis direction of the spindle shaft to one another. However, the positioning unit does not offer any support for the leading bearing or the stator, but simply facilitates the assembly of the spindle unit in the receiving opening. The positioning unit can be, for example, support rods which extend in the longitudinal axis direction of the spindle shaft and are connected on the outside to the leading bearing or to the bearing support or the stator carrying the leading bearing. The support rods can, for example, in order to ensure a flat contact of the leading bearing or bearing bracket and / or the stator in the receiving opening, in appropriately designed grooves extending in the longitudinal axis direction of the spindle shaft in the receiving opening or the leading bearing / bearing bracket and / or the stator run. The use of positioning aids designed as support rods, for example three or four support rods arranged at a uniform spacing over the circumference, improve the axial position of the leading bearing and the stator to each other and facilitates the 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 area between the leading bearing and the receiving opening and / or 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 with respect 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 energy conversion capacity 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 resetting 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 design 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, 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 of being elastic relative to the receiving opening to support.
Die Abstützung der Spindel in axialer Richtung kann grundsätzlich in beliebiger Weise erfolgen. 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.The spindle can be supported in the axial direction in principle in any manner. Thus, according to a preferred possible embodiment of the invention, the leading bearing for receiving the forces acting axially on the spindle can be designed as a fixed bearing. To transmit the axial forces to the spindle bench, according to a preferred embodiment of the invention, it is provided that the leading bearing rests in the longitudinal axis direction of the spindle shaft on a support surface which at least partially overlaps the receiving opening. The support surface can be, for example, a cover that closes the receiving opening, through which the spindle shaft projects in a preferred embodiment or which surrounds the spindle shaft. 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 bench, integrally formed on or fastened to the spindle bench. For example, the support surface can be a floor that delimits 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 bench. The support of the leading bearing, for example on a cover or base which closes the receiving opening on one side, also enables the spindle to be mounted in a damping manner in the receiving opening in a particularly simple manner, with damping means being arranged between the leading bearing and the cover or the base for this purpose .
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 manner. For example, these can be routed to a supply and / or control unit on the outside of the spindle bench. According to an advantageous embodiment of the invention, however, it is provided that the spindle bank has at least one connection line integrated in the spindle bank and connected to the spindle unit, which are preferably connected to a connection point arranged on an outside, in particular an end face, of the spindle bank.
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 within the spindle bank in such a way that it is protected against 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 front, of the spindle bank. This particularly preferred embodiment enables the spindle bench as a spindle bench section to be connected in a particularly simple and cost-effective manner to further spindle bench sections adjoining at the end, the common connecting 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 simply coupling several spindle banks, which then form individual spindle bench sections of a common spindle bench. An outside arrangement of a connection point can also be provided on the spindle bench in a preferred manner in such a way that corresponding current collectors can be easily supplied with electricity. An outside arrangement means all accessible side walls of the spindle bench, which physically limit the spindle bench. For example, the side walls of the spindle bench accessible within a receiving opening also form an outside for the arrangement of such a connection point.
Nach einem weiteren Aspekt der vorliegenden Erfindung wird eine Spindelbank zur Aufnahme einer Spindeleinheit für eine Spinnmaschine vorgeschlagen, wobei die Spindeleinheit 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. Erfindungsgemäß ist die Aufnahmeöffnung zur gehäuselosen Festlegung wenigstens eines, den Spindelschaft führenden Lagers und des Stators in der Aufnahmeöffnung ausgebildet.According to a further aspect of the present invention, a spindle bench for receiving a spindle unit for a spinning machine is proposed, the spindle unit having a spindle with a receiving section for detachable connection to a spinning sleeve and an electric motor with a rotor which is non-rotatably connected to a spindle shaft of the spindle. According to the invention, the receiving opening for housing-less fixing of at least one bearing guiding the spindle shaft and the stator is formed in the receiving opening.
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 pot-shaped. In other words, the receiving opening has a U-shaped or similar, for example V-shaped, cross-sectional shape in a cross-sectional plane that runs parallel to the direction of insertion of the spindle unit. This facilitates exact positioning of a lower bearing, for example directly on the floor or in the area of the bottom 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.Alternatively, the receiving opening in this cross-sectional plane can preferably have a cylindrical cross-sectional shape. In other words, the receiving opening 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 or the insertion direction to be received in the receiving opening, is open and thus accessible from the outside from both longitudinal axis directions. As a result, the spindle unit or individual components can be used in a simplified manner in the receiving opening and, if necessary, serviced, 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 that is transverse, in particular perpendicular, to the longitudinal axis direction, 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, quadrangle, etc.).
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 bench 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 bank and of 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, in order to reduce the manufacturing costs, the spindle bench can preferably be made from at least one lasered, punched or deep-drawn sheet-metal material.
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 else separate components which are arranged on the cover closing the receiving opening. The sealing unit is designed to prevent dirt from entering the receiving opening, which can lead to faults 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 bench allows the spindle unit to be designed without a bearing and / or an outer housing. The receiving opening is designed in such a way that the leading bearing is arranged directly or indirectly, for example via a bearing carrier receiving the leading bearing, and the stator is arranged in the receiving opening in a rotationally fixed manner and in the required manner in the axial direction. The possibility of arranging the spindle unit on the spindle bench without a housing allows the spindle bench to be designed in a particularly compact and cost-effective manner, since the housing surrounding the spindle unit can be dispensed with.
