Description
Die Erfindung betrifft eine Vorrichtung zur Lagerung einer Spinn-, Zwirn- oder Umwindespindel nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for mounting a spinning, twisting or winding spindle according to the preamble of claim 1.
Solche Lagerungen sind beispielsweise in der CH-444 584 vorgeschlagen worden.Such bearings have been proposed, for example, in CH-444 584.
Die in dieser Druckschrift gezeigten Spindellagerungsvarianten weisen alle Kugel- oder Kugelkalottenlager zwischen einer Lagerhülse und einem Kragen bzw. einer Platte auf, die ihrerseits über Federn mit einem feststehenden Maschinenteil verbunden sind. Durch das Erfordernis zusätzlicher Federelemente sind diese bekannten Lagerungen jedoch relativ aufwendig in der Fertigung und damit teuer.The spindle bearing variants shown in this document all have ball or spherical cap bearings between a bearing sleeve and a collar or a plate, which in turn are connected to a stationary machine part via springs. Due to the requirement of additional spring elements, these known bearings are relatively complex to manufacture and therefore expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine mit geringem Fertigungsaufwand herzustellende zusätzliche elastische Lagerung für Spindeln zu schaffen, bei der das Hals- und das Fußlager für die Spindel in beliebiger Weise gefedert in einem Lagergehäuse angeordnet sein können.The invention has for its object to provide an additional elastic storage for spindles to be produced with little manufacturing effort, in which the neck and foot bearings for the spindle can be arranged in any manner spring-loaded in a bearing housing.
Die Aufgabe wird mit einer Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Der innere Aufbau der Spindellagerung innerhalb des Lagergehäuses ist bei der erfindungsgemäßen Vorrichtung völlig beliebig. Es können hierfür sämtliche konventionellen Spindellagerungen eingesetzt werden. Die gewünschte zusätzliche elastische Lagerung entsteht durch das Gelenk am Fußbereich des Lagergehäuses, das einen Drehpunkt für Schwenkbewegungen des Lagergehäuses innerhalb des Außengehäuses bildet, wobei die Auslenkungen des Lagergehäuses im oberen Bereich radial abgefedert werden. Das Gelenk ist als Federgelenk ausgebildet, bei dem der Fußbereich des Lagergehäuses mit einer für die Schwenkbewegung elastischen Membran im Außengehäuse zusammenwirkt. Zur radialen Federung kann zwischen dem oberen Bereich des Lagergehäuses und dem Außengehäuse zweckmäßigerweise ein radial federndes Element angeordnet sein. Dieses radial federnde Element kann aus Metall bestehen und beispielsweise eine Spiralfeder sein. Aber auch ein Element aus einem Elastomer oder dergleichen kann hierfür eingesetzt werden. Hierbei kann das Außengehäuse einen Flansch zur Befestigung in einer Spinnmaschine aufweisen, wobei im Flanschbereich ein Hohlraum zur Anordnung des radial federnden Elementes vorgesehen sein kann. Das federnde Element kann jedoch auch eine nur geringe radiale Erstreckung und dafür eine relativ große Länge in axialer Richtung aufweisen. Auch die Anordnung mehrerer federnder Elemente, die sich in ihrer Wirkung ergänzen, ist möglich. Zum Schutz des radial federnden Elementes vor Deformationen kann außerdem eine Auslenkungsbegrenzung vorgesehen sein. Dies ist insbesondere bei von einem Tangentialriemen angetriebenen Spindeln von Vorteil, bei der hohe radial wirkende Bremskräfte auftreten. Eine zusätzliche Dämpfung der Bewegung des Lagergehäuses im Außengehäuse kann durch das Vorsehen eines Dämpfungsmediums wie Fett, Öl oder Polymerschaum in einem Zwischenraum zwischen Lagergehäuse und Außengehäuse erzielt werden. Da der Raum zwischen Lagergehäuse und Außengehäuse nicht mit dem Inneren des Lagergehäuses verbunden ist, können andere Medien als das Schmier- und Dämpfungsmedium der Spindellagerung als Dämpfungsmedium eingesetzt werden. Bei einem genügend großen Zwischenraum zwischen Lagergehäuse und Außengehäuse kann dort auch ein spiralgewickeltes und öl- oder fettgefülltes Dämpfungselement, beispielsweise ein gewickelter Blechstreifen angeordnet sein.The object is achieved with a device having the features of claim 1. The internal structure of the spindle bearing within the bearing housing is completely arbitrary in the device according to the invention. All conventional spindle bearings can be used for this. The desired additional elastic mounting is created by the joint at the base of the bearing housing, which forms a fulcrum for pivoting movements of the bearing housing within the outer housing, the deflections of the bearing housing being radially cushioned in the upper region. The joint is designed as a spring joint in which the foot region of the bearing housing interacts with a membrane in the outer housing that is elastic for the pivoting movement. For radial suspension, a radially resilient element can expediently be arranged between the upper region of the bearing housing and the outer housing. This radially resilient element can consist of metal and can be, for example, a spiral spring. However, an element made of an elastomer or the like can also be used for this. Here, the outer housing can have a flange for fastening in a spinning machine, wherein a cavity can be provided in the flange area for the arrangement of the radially resilient element. The resilient element can, however, also have only a small radial extension and therefore a relatively large length in the axial direction. The arrangement of several resilient elements that complement each other in their effect is also possible. A deflection limit can also be used to protect the radially resilient element from deformation be provided. This is particularly advantageous in the case of spindles driven by a tangential belt, in which high radially acting braking forces occur. Additional damping of the movement of the bearing housing in the outer housing can be achieved by providing a damping medium such as grease, oil or polymer foam in an intermediate space between the bearing housing and the outer housing. Since the space between the bearing housing and the outer housing is not connected to the inside of the bearing housing, media other than the lubricating and damping medium of the spindle bearing can be used as the damping medium. If the space between the bearing housing and the outer housing is large enough, a spirally wound and oil or grease-filled damping element, for example a wound sheet metal strip, can also be arranged there.
Zur Geräuschentkopplung zwischen Lagergehäuse und Außengehäuse kann das Gelenk zwischen Lagergehäuse und Außengehäuse zweckmäßigerweise aus einem anderen Werkstoff als die Gehäuse gefertigt sein. Auch durch eine in Geometrie und Werkstoff abgestimmte Membran kann eine Geräuschminderung bewirkt werden. Häufig ist auch eine Einstellmöglichkeit der relativen Lage von Lagergehäuse und Außengehäuse zueinander beispielsweise als Vorhaltung bei einem Tangentialriemenantrieb oder zur Kompensation von Herstellungstoleranzen erwünscht. Hierzu können entsprechende Einrichtungen im Fußbereich und im oberen Bereich des Außengehäuses vorgesehen sein. So kann die Einstellung der relativen Lage von Lagergehäuse und Außengehäuse beispielsweise im Fußbereich mittels einer Schraub- oder Klemmverbindung zwischen Lagergehäuse und Außengehäuse erfolgen. Jedoch auch eine Einstellung durch plastische Deformation eines Verbindungselementes ist denkbar. Die Einstellung der relativen Lage im oberen Bereich kann beispielsweise durch Aufnahme des Federelementes in zwei ineinandergefügte Scheiben mit exzentrischer Bohrung erfolgen. Außerdem können Sicherungen beispielsweise in Form von Anschlägen gegen eine axiale Bewegung des Lagergehäuses gegenüber dem Außengehäuse vorgesehen sein. Eine solche Sicherung ist dabei in beiden Richtungen zweckmäßig. Beim Kopswechsel können große Dofferkräfte auftreten, die beispielsweise durch eine Scheibe unter dem Einpreßbund zwischen Lagergehäuse und Außengehäuse oder durch eine Abstützkappe unterhalb eines Membrangelenkes zwischen Lagergehäuse und Außengehäuse aufgefangen werden können. Durch eine Deckscheibe am oberen Ende des Außengehäuses kann verhindert werden, daß beim Abziehen der Kopse das Spindeloberteil zusammen mit dem Lagergehäuse aus dem Außengehäuse herausgezogen wird. Das Außengehäuse kann das Lagergehäuse in radialer Richtung und nach unten hin vollständig umschließen, so daß ein Einfüllen des Dämpfungsmediums wie Fett vor Einbau des Lagergehäuses in das Außengehäuse möglich ist, wodurch sich die Montage der Vorrichtung vereinfacht.For noise decoupling between the bearing housing and the outer housing, the joint between the bearing housing and the outer housing can expediently be made of a different material than the housing. Noise can also be reduced by using a membrane that is matched in geometry and material. Frequently, it is also desirable to be able to adjust the relative position of the bearing housing and the outer housing to one another, for example as a reserve in a tangential belt drive or to compensate for manufacturing tolerances. For this purpose, appropriate devices can be provided in the foot area and in the upper area of the outer housing. For example, the relative position of the bearing housing and the outer housing can be set in the foot area by means of a screw or clamp connection between the bearing housing and the outer housing. However, adjustment by plastic deformation of a connecting element is also conceivable. The relative position in the upper region can be set, for example, by accommodating the spring element in two interlocking disks with an eccentric bore. In addition, fuses can be provided, for example in the form of stops against axial movement of the bearing housing relative to the outer housing. Such a backup is useful in both directions. When changing the cops, large doffer forces can occur, which can be absorbed, for example, by a washer under the press-fit collar between the bearing housing and the outer housing or by a support cap below a diaphragm joint between the bearing housing and the outer housing. A cover plate at the upper end of the outer housing can prevent the upper spindle part from being pulled out of the outer housing together with the bearing housing when the cops are removed. The outer housing can completely enclose the bearing housing in the radial direction and downwards, so that it is possible to fill the damping medium such as grease into the outer housing before installing the bearing housing, which simplifies the assembly of the device.
Nachfolgend wird ein bevorzugtes Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung anhand der Zeichnung näher erläutert.A preferred embodiment of a device according to the invention is explained in more detail below with reference to the drawing.
Die einzige Figur zeigt einen zentralen Längsschnitt durch eine Spindellagerung.The only figure shows a central longitudinal section through a spindle bearing.
Die Spindellagerung besteht aus einem Lagergehäuse 30, in dem eine aus einem Halslager 11 sowie einem Fußlager 12 bestehende Spindellagerung angeordnet ist. Das Fußlager 12 ist in radialer Richtung begrenzt beweglich im Lagergehäuse 30 angeordnet. Das Halslager 11 ist fest über eine Preßverbindung mit dem Lagergehäuse 30 verbunden. Zur Dämpfung der Bewegung des Fußlagers 12 ist eine Dämpfungsspirale 13 zwischen dem Fußlager 12 und der Innenwandung des Lagergehäuses 30 vorgesehen. Das Lagergehäuse 30 schließt die eigentliche Spindelaufnahme vollständig nach außen hin ab. Der gezeigte innere Aufbau des Lagergehäuses 30 ist lediglich beispielhaft. Hier sind auch andere Anordnungen von Halslager 11 und Fußlager 12 möglich. Das Lagergehäuse 30 ist in ein Außengehäuse 32 eingesetzt und in seinem Fußbereich 30.1 über ein Federgelenk 15, das von einer Membran 31 eines Außengehäuses 32 gebildet ist, am Außengehäuse 32 gelagert. In einem oberen Bereich 30.2 ist das Lagergehäuse 30 über ein Federelement 18, das hier von mehreren übereinander angeordneten Spiralfedern gebildet wird, in radialer Richtung federnd im Außengehäuse 32 angeordnet. In einem Zwischenraum 19 zwischen Lagergehäuse 30 und Außengehäuse 32 ist Fett als Dämpfungsmedium eingefüllt. Durch die Füllstandshöhe des Fettes im Zwischenraum 19 und durch die Federkennlinie des Federelementes 18 können Rückwirkungen des Gelenkes 15 auf Dämpfung und Federung einfach kompensiert werden. In seinem oberen Bereich 30.2 ist das Lagergehäuse 30 mit einem Einpreßbund 20 zur axialen Abzugssicherung im Außengehäuse 32 versehen. Zusätzlich ist eine Deckscheibe 21 von oben auf das Außengehäuse 32 aufgesetzt, die sowohl eine Abdichtung des Innenraumes des Außengehäuses 32 als auch einen axialen und radialen Anschlag für das Innengehäuse 30 bildet. Am unteren Bereich des Außengehäuses 32 ist eine Zentriervorrichtung 33 für das Gelenk 15 vorgesehen. Mit ihrer Hilfe kann die relative Lage des Lagergehäuses 30 zum Außengehäuse 32 eingestellt werden.The spindle bearing consists of a bearing housing 30 in which a spindle bearing consisting of a neck bearing 11 and a foot bearing 12 is arranged. The foot bearing 12 is arranged to be movable in the radial direction in the bearing housing 30. The neck bearing 11 is firmly connected to the bearing housing 30 via a press connection. To dampen the movement of the foot bearing 12, a damping spiral 13 is provided between the foot bearing 12 and the inner wall of the bearing housing 30. The Bearing housing 30 completely closes off the actual spindle receptacle from the outside. The internal structure of the bearing housing 30 shown is only an example. Other arrangements of neck bearing 11 and foot bearing 12 are also possible here. The bearing housing 30 is inserted into an outer housing 32 and is mounted on the outer housing 32 in its foot region 30.1 via a spring joint 15, which is formed by a membrane 31 of an outer housing 32. In an upper area 30.2, the bearing housing 30 is resiliently arranged in the radial direction in the outer housing 32 via a spring element 18, which is formed here by a plurality of spiral springs arranged one above the other. In an intermediate space 19 between the bearing housing 30 and the outer housing 32, grease is filled in as a damping medium. The fill level of the grease in the intermediate space 19 and the spring characteristic of the spring element 18 can easily compensate for the effects of the joint 15 on damping and suspension. In its upper region 30.2, the bearing housing 30 is provided with a press-in collar 20 for axial pull-off protection in the outer housing 32. In addition, a cover plate 21 is placed on the outer housing 32 from above, which forms both a seal of the interior of the outer housing 32 and an axial and radial stop for the inner housing 30. A centering device 33 for the joint 15 is provided on the lower region of the outer housing 32. With their help, the relative position of the bearing housing 30 to the outer housing 32 can be adjusted.
