Description

Die Erfindung betrifft eine Einrichtung zum radial beweglichen Befestigen eines Spindellagergehäuses einer Spinnoder Zwirnspindel an einer Spindelbank gemäss dem Oberbegriff des Patentanspruches 1.The invention relates to a device for the radially movable fastening of a spindle bearing housing of a spinning or twisting spindle to a spindle bench according to the preamble of patent claim 1.

Solche Einrichtungen sind bekannt. Beispielsweise ist bei der aus der CH-PS 509.430 bekannten Einrichtung das elastische Element eine im wesentlichen ringförmige Schichtfeder mit einem elastomeren Federkörper. Diese Schichtfeder umgibt mit Spiel das Spindellagergehäuse und ist zwischen einer auf der Oberseite der Spindelbank verankerten und das Spindellagergehäuse mit Spiel umgebenden Platte und einer ringförmigen, auf dem Spindellagergehäuse selbst aufgeschraubten Flanschhülse eingeklemmt. Das Spindellagergehäuse durchsetzt dabei mit Spiel eine in der Spindelbank ausgebildete Bohrung und auf seinem unter der Spindelbank befindlichen, mit einem Aussengewinde versehenen Teil ist eine eine Schulter aufweisende Mutter aufgeschraubt. Auf dieser Schulter ist das eine Ende einer kräftigen, das Spindellagergehäuse umgebende Druckfeder abgestützt, deren anderes Ende entweder an der Unterseite der genannten Platte oder an der Spindelbank selbst abgestützt ist. Diese Druckfeder soll die Schichtfeder in axialer Richtung vorkomprimieren und somit die axiale Beweglichkeit des Spindellagergehäuses auf einstellbare Weise stärker hemmen als dessen radiale Beweglichkeit. Wenn nun aber auf den riemengetriebenen Wirtel, der auf der Spindel sitzt, die ihrerseits in im Spindellagergehäuse angeordneten Lagern gelagert ist, die einseitig wirkende Zugkraft des Antriebsriemens einwirkt, dann wird die Schichtfeder zusätzlich einseitig auf Druck belastet mit der Folge, dass das ganze Spindellagergehäuse bezüglich der Spindelbank eine Schräglage einnimmt, was bei den überkritischen Drehzahlen, mit denen die Spindel angetrieben wird, und bei den unvermeidlichen Unwuchten des auf der Spindel sitzenden Garnkörpers zumindest unerwünscht ist.Such devices are known. For example, in the device known from CH-PS 509.430, the elastic element is an essentially annular layer spring with an elastomeric spring body. This layer spring surrounds the spindle bearing housing with play and is clamped between a plate anchored on the top of the spindle bank and the spindle bearing housing with play surrounding it and an annular flange sleeve screwed onto the spindle bearing housing itself. The spindle bearing housing penetrates with play a bore formed in the spindle bank and a nut having a shoulder is screwed onto its part, which is provided under the spindle bank and is provided with an external thread. On this shoulder is supported one end of a strong compression spring surrounding the spindle bearing housing, the other end of which is supported either on the underside of the plate mentioned or on the spindle bench itself. This compression spring is intended to pre-compress the layer spring in the axial direction and thus inhibit the axial mobility of the spindle bearing housing in an adjustable manner more than its radial mobility. However, if the belt-driven whorl that sits on the spindle, which in turn is mounted in bearings arranged in the spindle bearing housing, acts on the one-sided tensile force of the drive belt, then the layer spring is additionally loaded on one side with pressure, with the result that the entire spindle bearing housing is affected the spindle bank assumes an inclined position, which is at least undesirable given the supercritical speeds at which the spindle is driven and the unavoidable unbalance of the package sitting on the spindle.

Aehnliches gilt auch für die aus der DE-AS 1.685.971 vorbekannte Spindellagergehäusebefestigung, wenn bei dieser die (für niedrige Drehzahlen geeignete) feste Einspannung an der Spindelbank gelöst ist und die elastische Einlage zum Zuge kommt, wenn die Spindel mit höheren Drehzahlen anzutreiben ist. Bei dieser Befestigung hat das elastische, ebenfalls aus einem Elastomer bestehende Element die Form eines dickwandigen, hohlen, nach oben divergierenden Kegelstumpfes, dessen äussere Mantelfläche unmittelbar an der gegengleich geformten Innenseite eines auf der Spindelbank festgeschraubten ringförmigen Elementes aufvulkanisiert ist, während dessen innere Mantelfläche an der gegengleich geformten Aussenfläche einer auf dem Spindellagergehäuse verspannten Hülse aufvulkanisiert ist. Auch hier bewirkt der Riemenzug auf den Wirtel unweigerlich eine Schrägstellung des Spindellagergehäuses, die nur behoben werden kann, wenn dieses wieder fest mit der Spindelbank verspannt ist, was aber beim Betrieb mit überkritischen Drehzahlen zu unerwünschten Vibrationen der Spindelbank führt.The same applies to the spindle bearing housing fastening known from DE-AS 1.685.971, if the fixed clamping (suitable for low speeds) on the spindle bench is released and the elastic insert comes into play when the spindle is to be driven at higher speeds. With this attachment, the elastic element, which also consists of an elastomer, has the shape of a thick-walled, hollow, upwardly diverging truncated cone, the outer surface of which is vulcanized directly onto the opposite-shaped inside of an annular element which is screwed onto the spindle bench, while the inner surface of which is vulcanized is vulcanized on the outer surface of a sleeve clamped on the spindle bearing housing. Here, too, the belt tension on the whorl inevitably causes the spindle bearing housing to be tilted, which can only be remedied if it is firmly clamped to the spindle bench again, but this leads to undesirable vibrations of the spindle bench when operating at supercritical speeds.

Was für die Einrichtung gemäss der CH-PS 509.430 gesagt wurde, gilt im wesentlichen auch für die aus der DE-OS 2.211.488 bekannte Textilspindellagerung. Hier ist eine dreieckige, obere Platte auf dem Spindellagergehäuse und eine ähnlich geformte untere Platte fest auf der Spindelbank aufgeschraubt, wobei sich das Spindellagergehäuse mit Spiel durch eine zentrale Oeffnung der unteren Platte erstreckt. Die beiden Platten sind an ihren Ecken mit Bolzen und Muttern unter Zwischenlage einer Gummitülle miteinander verbunden. Auch hier bewirkt der Riemenzug auf den Wirtel eine Schrägstellung der oberen Platte und mithin eine Schrägstellung des Spindellagergehäuses, wobei zu dieser . Schrägstellung nicht nur die vom Riemenzug herrührende ungleichmässige Druckbelastung der Gummitüllen, sondern möglicherweise auch eine federnde Auswölbung der relativ dünnen oberen Platte beiträgt.What was said for the device according to CH-PS 509.430 also essentially applies to the textile spindle bearing known from DE-OS 2,211,488. Here, a triangular, upper plate is screwed onto the spindle bearing housing and a similarly shaped lower plate is firmly screwed onto the spindle bench, the spindle bearing housing extending with play through a central opening in the lower plate. The corners of the two plates are connected by bolts and nuts with the interposition of a rubber grommet. Here, too, the belt tension on the whorl causes the upper plate to be inclined, and thus causes the spindle bearing housing to be inclined, with respect to this. Inclination not only contributes to the uneven pressure loading of the rubber grommets resulting from the belt pull, but possibly also a resilient bulging of the relatively thin upper plate.

Schliesslich ist auch noch die aus der CH-PS 528.028 bekannte Lagervorrichtung zu erwähnen, für die im wesentlichen dasselbe gilt, wie für die Einrichtung gemäss der CH-PS 509.430. Der wesentliche Unterschied besteht bei dieser Lagervorrichtung, dass das elastische Element keine Schichtfeder ist, sondern ein Gummiring, der unterhalb der Spindelbank angeordnet ist und mit seiner unteren Flachseite auf der oberen Seite des unteren Endflansches einer fest mit der Spindelbank verspannten Hülse und an seiner oberen Flachseite auf einem nach innen ragenden Endflansch eines auf dem Spindellagergehäuse aufgeschraubten und den Gummiring übergreifenden weiteren Gehäuseteiles aufliegt.Finally, the storage device known from CH-PS 528.028 should also be mentioned, for which essentially the same applies as for the device according to CH-PS 509.430. The main difference in this bearing device is that the elastic element is not a layer spring, but a rubber ring, which is arranged below the spindle bench and with its lower flat side on the upper side of the lower end flange of a sleeve firmly clamped to the spindle bench and on its upper flat side rests on an inwardly projecting end flange of a further housing part screwed onto the spindle bearing housing and overlapping the rubber ring.

Bei diesem Stand der Technik ist es ein Zweck der Erfindung, eine Einrichtung der eingangs genannten Art zu schaffen, die dem Spindellagergehäuse im wesentlichen nur eine radiale Ausweichmöglichkeit bietet, wobei aber die Achse des Spindellagergehäuses selbst bei einer radialen Verschiebung desselben praktisch keine Neigung erfährt.In this prior art, it is a purpose of the invention to provide a device of the type mentioned which essentially only offers the spindle bearing housing a radial alternative, but the axis of the spindle bearing housing experiences practically no inclination even when the same is radially displaced.

Dieser Zweck wird mit der vorgeschlagenen Einrichtung dadurch erreicht, dass sie die Merkmale des Kennzeichens des Patentanspruches 1 aufweist.This purpose is achieved with the proposed device in that it has the features of the characterizing part of patent claim 1.

Der Kranz der Biegefederstäbe zusammen mit den Halterungshülsen bildet somit eine Art « räumliches Parallelogramm », das eine Verschiebung der anderen Halterungshülse praktisch nur rechtwinklig zu deren Achse zulässt. Da diese andere Halterungshülse aber fest mit dem Spindellagergehäuse verbunden ist, wird sich dieses ohne Schrägstellung nur radial gegen die Wirkung der Biegefederstäbe auslenken lassen.The wreath of the flexible spring bars together with the mounting sleeves thus forms a kind of «spatial parallelogram», which practically only allows the other mounting sleeve to be displaced at right angles to its axis. However, since this other mounting sleeve is firmly connected to the spindle bearing housing, this can only be deflected radially against the action of the spiral spring bars without inclination.

Bevorzugte Ausführungsformen der Einrichtung weisen die in den abhängigen Ansprüchen angegebenen Merkmale auf.Preferred embodiments of the device tion have the features specified in the dependent claims.

Die erfindungsgemässe Einrichtung ist nachstehend rein beispielsweise anhand der Zeichnung näher beschrieben. Es zeigt :

  • Fig. 1 eine Einrichtung im Längsschnitt etwa längs der Linie I-I der Fig. 3, wobei das Spindellagergehäuse ungeschnitten in Ansicht dargestellt ist.
  • Fig. 2 eine Ansicht des federelastischen Elementes,
  • Fig. 3 einen Schnitt längs der Linie 111-111 der Fig. 2, und
  • Fig. 4 einen Schnitt ähnlich wie Fig. 3 durch eine Ausführungsvariante.
The device according to the invention is described below purely by way of example with reference to the drawing. It shows :
  • Fig. 1 shows a device in longitudinal section approximately along the line II of Fig. 3, the spindle bearing housing is shown uncut in view.
  • 2 is a view of the resilient element,
  • Fig. 3 is a section along the line 111-111 of Fig. 2, and
  • Fig. 4 shows a section similar to Fig. 3 through an embodiment.

Bei der in Fig. 1 dargestellten Einrichtung 10 erkennt man im Schnitt einen Teil einer Spindelbank 11, die Bestandteil einer Spinn- oder Zwirnmaschine mit einer Mehrzahl von unter sich gleichen Spindeln ist. Die Spindelbank 11 weist für jede Spindel eine durchgehende Bohrung 12 auf. Die Spindel besteht aus einem Spindellagergehäuse 13, in dem eine Lagerhülse (nicht dargestellt) angeordnet ist. Ein Spindelschaft 14 erstreckt sich in diese Lagerhülse hinein und ist dort in der Regel mittels eines Halslagers 15 und eines Fusslagers 16 (in Fig. 1 gestrichelt angedeutet) drehbar derart gelagert, dass der Spindelschaft 14 zusätzlich zu seiner Drehbewegung auch noch Taumelbewegungen um ein etwa auf der Höhe des Halslagers 15 befindliches Zentrum ausführen kann, wobei diese Taumelbewegungen gegen die Wirkung einer zentrierenden Dämpfungseinrichtung (nicht dargestellt) erfolgt, die ebenfalls im Spindellagergehäuse 13 untergebracht ist.In the device 10 shown in FIG. 1, part of a spindle bank 11 can be seen in section, which is part of a spinning or twisting machine with a plurality of identical spindles. The spindle bank 11 has a through bore 12 for each spindle. The spindle consists of a spindle bearing housing 13, in which a bearing sleeve (not shown) is arranged. A spindle shaft 14 extends into this bearing sleeve and is rotatably supported there as a rule by means of a neck bearing 15 and a foot bearing 16 (indicated by dashed lines in FIG. 1) in such a way that the spindle shaft 14, in addition to its rotary movement, also wobbles by approximately the height of the neck bearing 15 can perform center, this wobble against the action of a centering damping device (not shown), which is also housed in the spindle bearing housing 13.

Auf dem aus dem Spindellagergehäuse 13 heraus sich erstreckenden Teil des Spindelschaftes 14 sitzt ein Spulendorn 17 mit einem angeformten Antriebswirtel 18, der das obere Ende des Spindellagergehäuses 13 umgibt.On the part of the spindle shaft 14 which extends out of the spindle bearing housing 13 there is a coil mandrel 17 with an integrally formed drive whorl 18 which surrounds the upper end of the spindle bearing housing 13.

Das Spindellagergehäuse 13 ist nur über das mit der Bezugsziffer 19 bezeichnete federelastische Element an der Spindelbank 11 befestigt. Diesesfederelastische Element weist in dem in Fig. 1-3 gezeigten Beispiel einen Kranz von vier Biegefederstäben (20) auf, die (unausgelenkt) parallel zur Achse 21 des Spindellagergehäuses 13 verlaufen und in regelmässigen Winkelabständen voneinander angeordnet sind. Diese Biegefederstäbe 20 haben einen rechteckigen Querschnitt (Fig. 3), dessen Schmalseiten etwa radial gerichtet sind. Die Biegefederstäbe 20 gehen an ihrem oberen Ende von einer Halterungshülse 22 mit einem Flansch 23 aus, der mittels Bolzen 24 auf der Oberseite der Spindelbank 11 festgeschraubt ist. Sodann erstrecken sich die Biegefederstäbe 20 mit radialem Spiel sowohl gegenüber der Innenwand der Bohrung 12 (Spalt 24') als auch gegenüber der Aussenwand des Spindellagergehäuses 13 (Spalt 25) nach unten, um sodann in eine andere Halterungshülse 26 überzugehen, in der das untere Ende des Spindellagergehäuses 13 im Pressitz, gegebenenfalls unter Zuhilfenahme weiterer Befestigungsmittel, beispielsweise einer Verklebung, festsitzt. Wie aus der Zeichnung ersichtlich, sind die Biegefederstäbe 20 mit den Halterungshülsen 22, 26 einstückig ausgeführt, wobei die Biegefederstäbe 20 in ihren Uebergangsbereichen in die Halterungshülse 22, 26 einen zunehmenden Querschnitt und damit eine zunehmende Steifigkeit aufweisen. Durch diesen Aufbau lässt sich die untere, fest mit dem Spindellagergehäuse 13 verbundene Halterungshülse 26 zwar quer zu der Achse 21 verschieben, aber sie wird keinesfalls verkippt, denn die Biegefederstäbe 20 lassen sich nur ausbiegen, während ihre allfällige Dehnung im Vergleich zum Mass der Ausbiegung vernachlässigbar ist.The spindle bearing housing 13 is fastened to the spindle bench 11 only via the spring-elastic element designated by the reference number 19. In the example shown in FIGS. 1-3, this spring-elastic element has a ring of four spiral spring bars (20) which (undeflected) run parallel to the axis 21 of the spindle bearing housing 13 and are arranged at regular angular intervals from one another. These spiral spring bars 20 have a rectangular cross section (FIG. 3), the narrow sides of which are directed approximately radially. The bending spring rods 20 start at their upper end from a mounting sleeve 22 with a flange 23 which is screwed onto the top of the spindle bench 11 by means of bolts 24. The spiral spring bars 20 then extend with radial play downward both with respect to the inner wall of the bore 12 (gap 24 ') and with respect to the outer wall of the spindle bearing housing 13 (gap 25), in order to then pass into another holding sleeve 26 in which the lower end of the spindle bearing housing 13 in the press fit, optionally with the aid of further fastening means, for example an adhesive, stuck. As can be seen from the drawing, the bending spring bars 20 are made in one piece with the mounting sleeves 22, 26, the bending spring bars 20 having an increasing cross section and thus increasing rigidity in their transition regions into the mounting sleeve 22, 26. With this construction, the lower mounting sleeve 26, which is firmly connected to the spindle bearing housing 13, can be moved transversely to the axis 21, but it is not tilted in any way, because the spiral spring bars 20 can only be bent out, while their possible expansion is negligible in comparison to the extent of the bending is.

Das Mass, um welches das Spindellagergehäuse 13 sich radial und parallel zu sich selbst verschieben lässt, ist im wesentlichen durch die Breite des Spaltes 25 gegeben.The extent to which the spindle bearing housing 13 can be moved radially and parallel to itself is essentially given by the width of the gap 25.

Die Fig. 2 lässt auch erkennen, dass sich das einstückige Element 19 leicht herstellen lässt. Entweder geschieht dies spanabhebend, indem zur Bildung der Biegefederstäbe 20 ovale, langgestreckte Durchbrechungen 27 in ein rohrförmiges Ausgangsteil gefräst werden, oder aber das Element 19 kann auch als Druckgussteil aus einer Legierung hergestellt werden, die ausreichend elastische Eigenschaften aüfweist, welche die geringen, möglichen Ausbiegungen der Biegefederstäbe 20 gewährleisten.2 also shows that the one-piece element 19 can be easily manufactured. Either this is done by machining, in order to form the flexible spring bars 20, oval, elongated openings 27 are milled into a tubular starting part, or the element 19 can also be produced as a die-cast part from an alloy which has sufficient elastic properties, which the small, possible bends ensure the bending spring bars 20.

In Fig. 4 ist eine Ausführungsvariante des Elementes 19 dargestellt, das fünf Biegefederstäbe 20' mit rundem Querschnitt aufweist.FIG. 4 shows an embodiment variant of the element 19 which has five spiral spring bars 20 'with a round cross section.

Das Element 19 braucht nicht einstückig zu sein. Es können auch Biegefederstäbe (beispielsweise aus glasfaserverstärktem Kunststoff) verwendet werden, die beiderends in einer gesonderten Halterungshülse verankert sind. Ebenso ist es nicht zwingend notwendig, die Halterungshülse 22, die an der Spindelbank 11 befestigt ist, an deren Oberseite zu verankern.The element 19 need not be in one piece. Bending spring bars (for example made of glass fiber reinforced plastic) can also be used, which are anchored at both ends in a separate mounting sleeve. Likewise, it is not absolutely necessary to anchor the mounting sleeve 22, which is fastened to the spindle bench 11, on the upper side thereof.

Ein weiterer Vorteil der beschriebenen Einrichtung besteht darin, dass sie sich ohne grosse Umbauarbeiten auch auf bestehenden Spinnmaschinen anwenden lässt, denn sie bedingt weder am Spindellagergehäuse noch an der Spindelbank eine besondere Formgebung. Ausserdem ist die Einrichtung absolut alterungsbeständig im Gegensatz zu jenen Lagerbefestigungen in denen Gummi als Federungs- oder Dämpfungselement herbeigezogen ist.Another advantage of the described device is that it can also be used on existing spinning machines without major modifications, because it does not require a special shape either on the spindle bearing housing or on the spindle bench. In addition, the device is absolutely aging-resistant in contrast to those bearing attachments in which rubber is used as a suspension or damping element.
