Abstract

In a spindle having an individual electromotive drive for a spinning machine, the drive (8, 10) is located at the lower spindle end and the bearing (3) is located in the middle portion. The bearing is held on the spindle rail (7), with damping elements (20, 21) being interposed, the stator (10) of the drive preferably being fastened to the housing of the bearing (1). This arrangement reduces resonances and natural vibrations of the spindle (1) by shifting these phenomena towards higher speeds outside the normal operating-speed range. <IMAGE>

Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung bezieht sich auf eine Spindel mit elektromoto­rischem Einzelantrieb für eine Spinnereimaschine, die an ei­ner Spindelbank anbringbar ist und die einen in einem Lager­gehäuse gelagerten Schaft aufweist, der drehfest mit einem Rotor verbunden ist, dessen zugehöriger Stator drehfest mit dem an der Spindelbank gehaltenen Lagergehäuse verbunden ist. Mit diesem Oberbegriff nimmt die Erfindung Bezug auf einen Stand der Technik, wie er sich beispielsweise aus der EP-An­meldung 0 304 869 ergibt.The invention relates to a spindle with a single electric motor drive for a spinning machine, which can be attached to a spindle bench and which has a shaft mounted in a bearing housing, which is connected in a rotationally fixed manner to a rotor, the associated stator of which is connected in a rotationally fixed manner to the bearing housing held on the spindle bench is. With this preamble, the invention relates to a state of the art, as it results for example from EP application 0 304 869.

TECHNOLOGISCHER HINTERGRUND UND STAND DER TECHNIKTECHNOLOGICAL BACKGROUND AND PRIOR ART

Spindeln von modernen Ringspinnmaschinen mit elektromotori­schem Einzelantrieb sind in schwingungstechnischer Hinsicht komplexe Gebilde. Bedingt durch den Kopsaufbau ändert sich die schwingfähige Masse und damit die kritische Drehzahl der Spindel. Umwuchten treten auf. Diese führen zu erhöhten La­gerbelastungen und auch zu vertikalen Schwingbewegungen (Spindelhüpfen), wodurch insbesondere beim Ringspinnen der Kopsaufbau gestört werden kann.Spindles of modern ring spinning machines with single electric motor drives are complex structures in terms of vibration technology. Due to the structure of the cops, the vibratable mass changes and thus the critical speed of the spindle. Balancing occurs. These lead to increased bearing loads and also to vertical swinging movements (spindle hopping), which can interfere with the build-up of the cops, especially during ring spinning.

Um derartige Schwingbewegungen zu eliminieren, wird in der EP-Anmeldung 0 304 869 vorgeschlagen, auf die Spindel einen in Richtung des Fusslagers wirkenden Zug auszuüben, z.B. durch axiale Versetzung des Stators gegenüber dem Rotor in Richtung des Fusslagers. Das Problem der kritischen Drehzah­len wird damit jedoch nicht gelöst.In order to eliminate such oscillating movements, it is proposed in EP application 0 304 869 to exert a tension on the spindle in the direction of the foot bearing, for example by axially displacing the stator with respect to the rotor in the direction of the foot bearing. However, this does not solve the problem of critical speeds.

KURZE DARSTELLUNG DER ERFINDUNGSUMMARY OF THE INVENTION

Ausgehend vom Stand der Technik liegt der Erfindung die Auf­gabe zugrunde, eine Spindel mit elektromotorischem Einzelan­trieb mit verminderten Resonanzen und Eigenschwingungen zu schaffen.Starting from the prior art, the invention has for its object to provide a spindle with a single electric motor drive with reduced resonances and natural vibrations.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass Spindelschaft im wesentlichen nur zwischen dem Rotor und dem oberen freien Ende des Spindelschafts gelagert ist und das Lagergehäuse über Dämpfungselemente an der Spindelbank gehal­ten ist.
Bei einer ansonsten baugrössengleichen Spindel ändert sich die Massenverteilung des Rotationskörpers so grundlegend, dass die biegekritische Drehzahl hin zu höheren Drehzahlen steigt und weit über der normalen Betriebsdrehzahl liegt.This object is achieved according to the invention in that the spindle shaft is mounted essentially only between the rotor and the upper free end of the spindle shaft and the bearing housing is held on the spindle bench by means of damping elements.
With an otherwise identical-sized spindle, the mass distribution of the rotating body changes so fundamentally that the bending-critical speed increases towards higher speeds and is far above the normal operating speed.

Das vorzugsweise als kombiniertes Radial- und Axiallager aus­gebildete Lager ist vorzugsweise in eine Ausnehmung in der Spindelbank angeordnet, der Stator samt seinem Gehäuse von unten über den (drehfest mit dem unteren Spindelende verbun­denen) Rotor gestülpt und an einen Flansch oder Bund am La­gergehäuse geschraubt. Wesentlich bei beiden Varianten ist die Zwischenschaltung gummielastischer Dämpfungselemente zwi­schen feststehendem Lagerteil und Lagergehäuse.The bearing, which is preferably designed as a combined radial and axial bearing, is preferably arranged in a recess in the spindle bank, the stator and its housing are placed from below over the rotor (connected to the lower spindle end in a rotationally fixed manner) and screwed to a flange or collar on the bearing housing. It is essential in both variants to interpose rubber-elastic damping elements between the fixed bearing part and the bearing housing.

Weitere Einzelheiten der Erfindung und die daraus resultie­renden Vorteile ergeben sich aus den in der Zeichnung darge­stellten Ausführungsbeispielen.Further details of the invention and the resulting advantages result from the exemplary embodiments shown in the drawing.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

Die Spindel mit elektromotorischem Einzelantrieb gemäss Fig. 1 umfasst im wesentlichen einen Schaft 1, der in seinem mit­tigen Abschnitt in einem kombinierten Axial-/Radiallager 2 gelagert ist. Das Lager 2 ist von einem zweiteiligen Lagerge­häuse (innere 16 und äussere Lageraufnahmehülse 17) umgeben, das an beiden Enden Flansche 4 und 5 aufweist. Das Lagerge­häuse ist mittels Schrauben 6 an einer Spindelbank 7 befe­stigt.1 essentially comprises a shaft 1, which is mounted in its central section in a combined axial / radial bearing 2. The bearing 2 is surrounded by a two-part bearing housing (inner 16 and outer bearing receiving sleeve 17) which has flanges 4 and 5 at both ends. The bearing housing is fastened to a spindle bench 7 by means of screws 6.

Am unteren Ende der Spindel 1 ist drehfest ein Asynchronrotor 8 angebracht, der in üblicher Weise aufgebaut ist, d.h. ein Blechpaket mit einem aus Stäben und Kurzschlussringen gebil­deten Käfig aufweist, das als ganzes von einer Ankerhülse 9 getragen ist, die auf das untere Ende der Spindel 1 aufge­presst ist. Anstelle eines Asynchronmotors kann selbstver­ständlich auch ein anderer Motortyp verwendet werden.At the lower end of the spindle 1, an asynchronous rotor 8 is rotatably attached, which is constructed in the usual way, i.e. has a laminated core with a cage formed from rods and short-circuit rings, which is supported as a whole by an anchor sleeve 9 which is pressed onto the lower end of the spindle 1. Instead of an asynchronous motor, another type of motor can of course also be used.

Der zugehörige Stator 10 besitzt ein Blechpaket 11 und eine Wicklung 12, die in Nuten des Blechpakets 11 eingelegt ist.The associated stator 10 has a laminated core 11 and a winding 12 which is inserted into the slots in the laminated core 11.

Der Stator 10 ist in ein topfförmiges Statorgehäuse 13 einge­schoben, vorzugsweise eingepresst. Die Befestigung des Sta­torgehäuses 13 und damit des Stators 10 am unteren Flansch 5 des Lagergehäuses 3 erfolgt mittels Schrauben 14.The stator 10 is inserted, preferably pressed, into a pot-shaped stator housing 13. The stator housing 13 and thus the stator 10 are fastened to the lower flange 5 of the bearing housing 3 by means of screws 14.

Die lichte Weite der Bohrung 15 in der Spindelbank 7 ist nur wenig grösser bemessen als der maximale Aussendurchmesser des Statorgehäuses 13. Dies erlaubt die Montage der Spindel 1 einschliesslich aller ihrer Bestandteile von oben her.The clear width of the bore 15 in the spindle bank 7 is dimensioned only a little larger than the maximum outer diameter of the stator housing 13. This allows the spindle 1, including all of its components, to be mounted from above.

Zur schwingungsmässigen Entkopplung der Spindel 1 von der Spindelbank 7 ist das Lagergehäuse 3 im wesentlichen zweitei­lig ausgebildet und beteht aus einer inneren Lageraufnahme­hülse 16, die am unteren Ende mit dem unteren Flansch 5 ein­stückig verbunden ist, und einer von der Lageraufnahmehülse radial beabstandeten äusseren Lageraufnahmehülse 17, die am oberen Ende den oberen Flansch 4 trägt. Die äussere Lagerauf­nahmehülse 17 ist an beiden Enden mit Eindrehungen 18, 19 versehen, deren eine Wand achsparallel ist, während die an­dere Wand etwa 60° gegenüber der Spindelachse geneigt ist. In die durch die innere Hülse 16 und die beiden Eindrehungen 18, 19 gebildete Räume sind O-Ringe 20, 21 aus gummielastischem Material eingelegt. Die gegenseitige Verspannung der äusseren 17 und inneren Lageraufnahmehülse 16 erfolgt durch einen Druckring 22, der entweder auf die innere Lageraufnahmehülse geschraubt oder, wie im Beispielsfall durch einen Sicherungs­ring 23, der in eine Ringnut 24 an der inneren Lageraufnahme­hülse 16 eingreift.For the vibration decoupling of the spindle 1 from the spindle bank 7, the bearing housing 3 is essentially formed in two parts and consists of an inner bearing receiving sleeve 16, which is integrally connected at the lower end to the lower flange 5, and an outer bearing receiving sleeve 17 radially spaced from the bearing receiving sleeve. which carries the upper flange 4 at the upper end. The outer bearing receiving sleeve 17 is provided at both ends with recesses 18, 19, one wall of which is axially parallel, while the other wall is inclined approximately 60 ° with respect to the spindle axis. In the spaces formed by the inner sleeve 16 and the two recesses 18, 19, O-rings 20, 21 made of rubber-elastic material are inserted. The mutual bracing of the outer 17 and inner bearing receiving sleeve 16 takes place by means of a pressure ring 22, which is either screwed onto the inner bearing receiving sleeve or, as in the example by a locking ring 23, which engages in an annular groove 24 on the inner bearing receiving sleeve 16.

Auf diese Weise sind neben allen rotierenden Teilen auch der Stator 10 samt Gehäuse 13 von der Spindelbank 7 entkoppelt. Dabei erfüllen neben der Dämpfung die O-Ringe 20, 21 auch Di­stanzierungsfunktion.In this way, in addition to all rotating parts, the stator 10 together with the housing 13 are decoupled from the spindle bench 7. In addition to the damping, the O-rings 20, 21 also perform a spacing function.

Die Befestigung des Stators 10 an der inneren Lageraufnahme­hülse 16 hat den zusätzlichen Vorteil, dass Ungenauigkeiten bei der Spindelmontage die Zentrierung zwischen Rotor 8 und Stator 10 nicht beeinflusssen. Auch tritt kein Streifen des Rotors 8 am Stator beim Hochfahren des Spindelantriebs auf.The attachment of the stator 10 to the inner bearing receiving sleeve 16 has the additional advantage that inaccuracies in the spindle assembly do not influence the centering between the rotor 8 and the stator 10. There is also no streaking of the rotor 8 on the stator when the spindle drive is started up.

Ein weiterer Vorteil ist darin zu sehen, dass die gesamte Spindel von oben in die Spindelbank eingesetzt werden kann. Der prinzipielle Aufbau des Lagers 2 geht im wesentlichen aus den Figuren 2 und 3 hervor. Derartige Lager sind bekannt und können von Kugellagerherstellern z.T. schon mit Spindel bezo­gen werden (vgl. z.B. DE-Zeitschrift "mittex" 4/88, S. 67, Bild 2 und 3).Another advantage is that the entire spindle can be inserted into the spindle bank from above. The basic structure of the bearing 2 can be seen essentially from FIGS. 2 and 3. Such bearings are known and can already be obtained from ball bearing manufacturers with a spindle (cf. eg DE magazine "mittex" 4/88, p. 67, fig. 2 and 3).

Nicht katalogmäsig lieferbar sind hingegen Lageranordnungen, wie sie in Fig. 2 und 3 beispielsweise verdeutlicht sind. Hier bildet die äussere, als langgestreckter Zylinder 25 aus­gebildete Lagerschale gleichzeitig die innere Lageraufnahme­hülse (Pos. 16 in Fig.1). Diese ist am unteren Ende mit einem Flansch 5′ versehen, an welchem das Statorgehäuse 13 und da­mit der Stator 10 angeschraubt ist. Die äussere Lageraufnah­mehülse 17, ihre Befestigung auf der Spindelbank 7 und ihre gummieleastische Abstützung auf dem Zylinder 25 über O-Ringe 20, 21 entspricht ansonsten der Fig. 1.However, bearing arrangements such as those illustrated in FIGS. 2 and 3 are not available in the catalog. Here the outer bearing shell, which is designed as an elongated cylinder 25, simultaneously forms the inner bearing receiving sleeve (item 16 in FIG. 1). This is provided at the lower end with a flange 5 'to which the stator housing 13 and thus the stator 10 is screwed. The outer bearing receiving sleeve 17, its fastening on the spindle bench 7 and its rubber-elastic support on the cylinder 25 via O-rings 20, 21 otherwise correspond to FIG. 1.

Bei der in Fig. 3 dargestellten Variante ist anstelle der äusseren Lageraufnahmehülse 17 ein Rohrstück 26 an der Spin­delbank 7 befestigt, welches die Funktion der Lageraufnahme­hülse 17 gemäss Fig. 1 oder 2 erfüllt. Es weist demgemäss an beiden Enden Eindrehungen 18, 19 auf, deren Geometrie in Zu­sammenhang mit Fig. 1 beschrieben wurde.In the variant shown in FIG. 3, instead of the outer bearing receiving sleeve 17, a tube piece 26 is fastened to the spindle bench 7 and fulfills the function of the bearing receiving sleeve 17 according to FIG. 1 or 2. Accordingly, it has indentations 18, 19 at both ends, the geometry of which was described in connection with FIG. 1.

Die Variante gemäss Fig. 3 ist den Ausführungen nach Fig. 1 und 2 funktionell gleichwertig; lediglich die Montage ist un­terschiedlich:The variant according to FIG. 3 is functionally equivalent to the versions according to FIGS. 1 and 2; only the assembly is different:

Die Spindel 1 incl. angeflanschtem Statorgehäuse 13 wird bei eingelegtem unterem O-Ring 20 von unten her in die Bohrung des Rohrstückes 26 eingefahren, der obere O-Ring aufgezo­gen.Mittels Druckring 22 werden die O-Ringe 20 und 21 gleichmässig verspannt.With the lower O-ring 20 inserted, the spindle 1 including the flanged stator housing 13 is inserted from below into the bore of the pipe section 26, the upper O-ring is pulled in. The O-rings 20 and 21 are clamped evenly by means of the pressure ring 22.

Es versteht sich von selbst, dass diese Variante auch bei ei­ner Spindel nach Fig. 1 angewandt werden kann. Bei der Spin­del mit elektromotorischem Einzelantrieb nach Fig. 4 im Ge­gensatz zu den bisher beschriebenen Ausführungsformen im we­sentlichen nur der rotierende Teil (im wesentlichen Spindel 1 und Rotor 8) gummielastisch gegenüber der Spindelbank 7 abge­stützt und entkoppelt. In Fig. 4 ist das kombinierte Radial­/Axiallager 2 von einer Hülse 27 mit einem nach aussen wei­ senden Vorsprung 27a am unteren Ende umgeben, auf die an bei­den Enden Gummiringe 28, 29 aufvulkanisiert sind. Diese Gum­miringe sind ihrerseits in die Innenbohrung 30 eines Doppel­flanschrohres 31 mit Flanschen 4˝ und 5˝ einvulkanisiert. Das Doppelflanschrohr 31 endet am oberen Ende in einem der Boh­rung 15 in der Spindelbank 7 angepassten zylindrischen Fort­satz 32.It goes without saying that this variant can also be used with a spindle according to FIG. 1. 4, in contrast to the previously described embodiments, essentially only the rotating part (essentially spindle 1 and rotor 8) is elastically supported and decoupled from the spindle bench 7. In Fig. 4, the combined radial / axial bearing 2 of a sleeve 27 with an outward white Send projection 27a surrounded at the lower end, on which rubber rings 28, 29 are vulcanized at both ends. These rubber rings are in turn vulcanized into the inner bore 30 of a double flange tube 31 with flanges 4˝ and 5˝. The double flange tube 31 ends at the upper end in a cylindrical extension 32 which is adapted to the bore 15 in the spindle bank 7.

Der Stator 10 samt Gehäuse 13 ist am unteren Flansch 5˝ mit­tels Schrauben 14, das Doppelflanschrohr selbst am oberen Flansch 4˝ mittels Schrauben 6 an der Spindelbank 7 befe­stigt.The stator 10 together with the housing 13 is attached to the lower flange 5˝ by means of screws 14, the double flange tube itself to the upper flange 4˝ by means of screws 6 on the spindle bench 7.

Ein Sicherungsring 33, der in eine Nut 34 in der Innenwandung des Doppelflanschrohres eingreift und mit dem Vorsprung 27a der Hülse 27 zusammenwirkt, sichert die gegenseitige axiale Lage von Lager 2 (und damit Spindel 1 und Rotor 8) und Dop­pelflanschrohr 31.A locking ring 33, which engages in a groove 34 in the inner wall of the double flange tube and interacts with the projection 27a of the sleeve 27, secures the mutual axial position of bearing 2 (and thus spindle 1 and rotor 8) and double flange tube 31.

In Analogie zur Ausführungsform nach Fig. 3 kann das Doppel­flanschrohr 31 auch fest mit der Spindelbank 7 verbunden sein. Der obere Flansch 4˝ entfällt dann. Um ein Auswechseln der Gummiringe 28, 29 zu gewährleisten, sind diese nicht di­rekt auf der Innenbohrung 30 des Doppelflanschrohres 31 auf­vulkanisiert, sondern auf die Innenwandung einer Buchse.In analogy to the embodiment according to FIG. 3, the double flange tube 31 can also be firmly connected to the spindle bench 7. The upper flange 4˝ is then omitted. In order to ensure replacement of the rubber rings 28, 29, they are not vulcanized directly onto the inner bore 30 of the double flange tube 31, but rather onto the inner wall of a bushing.
