Abstract
Description
Die Erfindung betrifft eine für Textilmaschinen, insbesondere Texturiermaschinen, geeignete Andruckrolle. Eine derartige Andruckrolle weist einen elastischen Bezug auf, der in einer Textilmaschine gegen eine angetriebene Walze gedrückt wird, wobei zwischen dieser Walze und dem Bezug ein Faden oder ein Faserstrang hindurchgeführt wird. Dieser wird damit entweder lediglich transportiert oder, wie in Spinn- oder Texturiermaschinen, auch verzogen.The invention relates to a textile machine, in particular texturing machines, suitable pressure roller. Such a pressure roller has an elastic cover, which is pressed in a textile machine against a driven roller, wherein between this roller and the cover, a thread or a fiber strand is passed. This is thus either merely transported or warped, as in spinning or texturing machines.
Eine Andruckrolle der eingangs genannten Art ist beispielsweise aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Andruckrolle für Textilmaschinen bei uneingeschränkter Funktionalität konstruktiv zu vereinfachen.The invention has for its object to simplify constructively a pinch roller for textile machines with full functionality.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Andruckrolle mit den Merkmalen des Anspruchs 1. Die zur Verwendung in Textilmaschinen, insbesondere Texturiermaschinen, vorgesehene Andruckrolle weist einen elastischen Bezug auf, der mittels eines Wälzlagers rotierbar auf einer Tragachse gelagert ist. Zum Ausgleich von Kippbewegungen des Innenrings des Wälzlagers relativ zur Tragachse ist zwischen der Tragachse und dem Innenring mindestens ein elastischer Ring, insbesondere aus einem Polymermaterial, angeordnet. Damit ist auf einfache und zuverlässige Weise eine Schwenkbeweglichkeit des Wälzlager-Innenrings um vorzugsweise 1,5° bis 5° gegeben.This object is achieved by a pinch roller having the features of
Gemäß einer ersten Variante sind mehrere elastische Ringe direkt oder indirekt zwischen der Tragachse und dem Innenring angeordnet. Hierbei sind die elastischen Ringe vorzugsweise als O-Ringe ausgebildet, wobei mindestens ein Ring in einer Nut an der Oberfläche der Tragachse einliegt. Im Gegensatz zur Tragachse weist der Innenring des Wälzlagers in vorteilhafter Ausgestaltung keine Nut auf, so dass hier keine Sonderkonstruktionen erforderlich sind. Zur Erzeugung von auf den Innenring wirkenden Axialkräften sind vorzugsweise gesonderte O-Ringe vorgesehen, welche - dem Innenring axial benachbart oder zumindest teilweise in Axialrichtung über den Innenring hinausragend - zwischen dem Innenring und jeweils einem auf der Tragachse gehaltenen Stützring angeordnet sind.According to a first variant, a plurality of elastic rings are arranged directly or indirectly between the support shaft and the inner ring. Here, the elastic rings are preferably formed as O-rings, wherein at least one ring rests in a groove on the surface of the support shaft. In contrast to the support shaft, the inner ring of the rolling bearing in an advantageous embodiment, no groove, so that no special constructions are required here. To generate axial forces acting on the inner ring, separate O-rings are preferably provided which are arranged axially adjacent to the inner ring or at least partially projecting beyond the inner ring in the axial direction between the inner ring and in each case one support ring held on the support shaft.
Der Stützring ist beispielsweise als auf die Tragachse aufgepresster Winkelring gestaltet. Ein derartiger Ring ist rationell alls spanlos umgeformtes Blechteil herstellbar. Alternativ kann der Stützring beispielsweise als spanend bearbeitetes Teil und/oder als integraler Bestandteil der Tragachse ausgebildet sein. Unabhängig vom Fertigungsverfahren weist nach einer besonders vorteilhaften Ausgestaltung eine einen elastischen Ring kontaktierende, dem Innenring zugewandte Oberfläche des Stützrings in Umfangsrichtung eine Wellenform mit zwei Wellenbergen und zwei Wellentälern auf. Damit ist eine Vorzugsrichtung gegeben, um welche der Innenring am leichtesten kippen kann.The support ring is designed, for example, as pressed onto the support shaft angle ring. Such a ring is rationally alls spanless transformed sheet metal part produced. Alternatively, the support ring may be formed, for example, as a machined part and / or as an integral part of the support shaft. Regardless of the manufacturing method, according to a particularly advantageous embodiment, an elastic ring contacting, the inner ring facing surface of the support ring in the circumferential direction has a waveform with two wave crests and two wave troughs. This is a preferred direction given by which the inner ring can tilt the easiest.
Nach einer zweiten Variante ist zwischen der Tragachse und dem Innenring lediglich ein einziger elastischer Ring angeordnet. Dieser ist jedoch nicht als O-Ring, sondern als komplexer geformtes Teil, welches in Axialrichtung breiter als der Innenring des Wälzlagers ist, ausgebildet. Die Oberfläche des elastischen Rings, auf welcher der Innenring aufliegt, beschreibt eine Sattelform, so dass auch in dieser Variante unter relativ geringer Krafteinwirkung ein Kippen des Wälzlagers um eine bestimmte, virtuelle Achse möglich ist, während das Wälzlager um eine hierzu orthogonale Achse nur unter wesentlich höherer Krafteinwirkung und/oder in geringerem Umfang kippbar ist.According to a second variant, only a single elastic ring is arranged between the support shaft and the inner ring. However, this is not as an O-ring, but as a complex shaped part, which is wider in the axial direction as the inner ring of the rolling bearing is formed. The surface of the elastic ring on which rests the inner ring, describes a saddle shape, so that in this variant under relatively little force tilting of the bearing about a specific, virtual axis is possible, while the roller bearing to an orthogonal axis only substantially below higher force and / or tilting to a lesser extent.
In jeder Variante ist mindestens ein elastischer Ring radial zwischen der Tragachse und dem Innenring angeordnet. Sofern diesem Ring weitere Ringe axial benachbart sind, welche ebenfalls der in radialer Richtung elastisch nachgiebigen Halterung des Innenrings auf der Tragachse dienen, wird die Kippbarkeit des Innenrings des Wälzlagers um die Tragachse dadurch begünstigt, dass der mittlere dieser drei Ringe den größten Querschnitt und/oder die größte Vorspannung aufweist. Eine weitere Verbesserung der Kippfunktion ist mit geölten oder befetteten O-Ringen erreichbar. In jedem Fall erfüllen die elastischen Ringe sowohl bei Belastungen in axialer Richtung als auch bei Belastungen in radialer Richtung eine Dämpfungsfunktion, die die maximale Gebrauchsdauer des Wälzlagers verlängert. Dies gilt auch für Ausführungsformen mit nur einem elastischen Ring.In each variant, at least one elastic ring is arranged radially between the support shaft and the inner ring. If this ring further axially adjacent rings, which also serve the elastically yielding support of the inner ring on the support shaft in the radial direction, the tiltability of the inner ring of the bearing about the support shaft is favored by the fact that the middle of these three rings the largest cross-section and / or has the largest bias. A further improvement of the tilting function can be achieved with oiled or greased O-rings. In any case, meet the elastic rings both under loads in the axial direction as well as loads in the radial direction of a damping function that extends the maximum service life of the bearing. This also applies to embodiments with only one elastic ring.
Nach einer vorteilhaften Weiterbildung ist das Wälzlager radial innerhalb eines Hülsenabschnitts eines Grundkörpers angeordnet, wobei der elastische Bezug der Andruckrolle auf dem Hülsenabschnitt des Grundkörpers gehalten ist. Radial zwischen dem Hülsenabschnitt und dem elastischen Bezug kann hierbei eine weitere, im Vergleich zum Bezug dünnwandige Hülse als Zwischenhülse vorgesehen sein. Letztgenannte Hülse sowie der Grundkörper sind bevorzugt als spanlos umgeformte Blechteile hergestellt. Ein Teil des Hülsenabschnitts ist vorzugsweise derart doppelwandig ausgebildet, dass ein Axialanschlag für den Außenring des Wälzlagers gebildet ist. Ausgehend vom Axialanschlag erstreckt sich in bevorzugter Ausgestaltung ein einstückig mit dem Hülsenabschnitt ausgebildeter Ringabschnitt des Grundkörpers konisch zum Ende der Tragachse zulaufend nach innen. Die vom Ringabschnitt begrenzte Öffnung im Grundkörper ist mit einer stirnseitig der Tragachse angeordneten Kappe verschließbar. Die mit dem elastischen Bezug rotierende Kappe ist soweit von der Stirnfläche der Tragachse beabstandet, dass eine Verkippung des gesamten Wälzlagers um eine gedachte Kippachse, welche orthogonal zur Tragachse verläuft, im erforderlichen Umfang, das heißt bis ca. 5°, möglich ist. Ebenso ist berücksichtigt, dass mittels des mindestens einen direkt oder indirekt auf der Tragachse angeordneten elastischen Rings auch eine zumindest geringfügige elastische Nachgiebigkeit des Wälzlagers und damit auch des Grundkörpers einschließlich des Hülsenabschnitts in axialer Richtung der Tragachse gegeben ist.According to an advantageous embodiment, the rolling bearing is arranged radially within a sleeve portion of a base body, wherein the elastic reference of the pressure roller is held on the sleeve portion of the base body. Radially between the sleeve portion and the elastic cover in this case a further, compared to the reference thin-walled sleeve can be provided as an intermediate sleeve. The latter sleeve and the base body are preferably produced as non-cutting formed sheet metal parts. A part of the sleeve portion is preferably formed double-walled such that an axial stop for the outer ring of the rolling bearing is formed. Starting from the axial stop extends in a preferred embodiment, an integrally formed with the sleeve portion ring portion of the body conically to the end of the support shaft tapering inward. The limited opening of the annular portion in the base body is closed with a front side of the support shaft arranged cap. The cap rotating with the elastic cover is far enough away from the end face of the carrying axle that a tilting of the entire rolling bearing about an imaginary tilting axis, which is orthogonal to the carrying axle, is possible to the required extent, that is to say approximately 5 °. Likewise, it is considered that by means of at least one elastic ring arranged directly or indirectly on the support axle, there is also given at least slight elastic compliance of the roller bearing and thus also of the base body including the sleeve portion in the axial direction of the support shaft.

Das Wälzlager 3 ist als Radialrillenkugellager ausgebildet und weist einen Innenring 6 sowie einen Außenring 7 auf, zwischen welchen Kugeln 8 als Wälzkörper abrollen. Der Innenring 6 ist, wie im Folgenden näher beschrieben, mit Hilfe von fünf O-Ringen elastisch nachgiebig, insbesondere kippbar, auf der Tragsachse 2 gehalten.The rolling
In einer mittig durch die Wälzkörper 8 verlaufenden Ebene E, das heißt in der normal zur Tragachse 2 angeordneten Symmetrieebene des Wälzlagers 3, befindet sich radial zwischen der Tragachse 2 und dem Innenring 6 ein zentraler O-Ring 9 aus einem elastischen Polymermaterial. Axial neben dem zentralen elastischen Ring 9 ist spiegelsymmetrisch zur Ebene E jeweils ein elastischer Ring 10 angeordnet, welcher ebenfalls den Innenring 6 in radialer Richtung abstützt. Zusammenfassend werden die sich im selben axialen Bauraum wie der Innenring 6 befindenden elastischen Ringe 9, 10 auch als Radialringe bezeichnet. Die äußeren Radialringe 10 weisen einen geringeren Querschnitt als der zentrale Radialring 9 auf und liegen jeweils in einer an der Oberfläche der Tragachse 2 gebildeten Nut 11 ein. Der zentrale O-Ring 9 liegt in einer Nut 12 ein, welche in Anpassung an den größeren Querschnitt des zentralen O-Rings 9 tiefer als die Nuten 11 ist. Die Radialringe 9,10 sowie die Nuten 11,12 sind derart bemessen, dass die über den zentralen O-Ring 9 auf den Innenring 6 übertragenen Radialkräfte, zumindest so lange - wie in
Um dem Innenring 6 die erforderliche Stabilität in Axialrichtung bei gleichzeitiger Erhaltung der Kippfähigkeit zu geben, sind zwei als Axialringe bezeichnete elastische Ringe 13 vorgesehen, die jeweils einerseits den Innenring 6 in dessen radial innerem Bereich an einer Stirnseite 14 und andererseits einen Winkelring 15, 16 kontaktieren. Der erste Winkelring 15 umgibt eine Stirnfläche 17 der Tragachse 2, während der zweite Winkelring 16 auf der einem abgeflachten Befestigungsende 18 zugewandten Seite des Wälzlagers 3 angeordnet ist. Im Gegensatz zum stirnseitigen Winkelring 15, welcher in radialer Richtung nicht über den Innenring 6 hinausragt, erstreckt sich der so genannte anschlussseitige Winkelring 16 radial bis zum Außenring 7.In order to give the
Der Außenring 7 ist in einen Hülsenabschnitt 19 des als Umformteil aus Blech gefertigten Grundkörpers 4 eingepresst. Der Hülsenabschnitt 19, auf welchem unter Zwischenschaltung einer Hülse 20 der elastische Bezug 5 der Andruckrolle 1 angeordnet ist, weist einen dem Befestigungsende 18 zugewandten einlagigen Abschnitt 21 sowie einen daran anschließenden doppelwandigen Abschnitt 22 auf. Am Übergang zwischen den Abschnitten 21, 22 ist ein Axialanschlag 23 für den Außenring 7 gebildet. An dieser Stelle geht der Hülsenabschnitt 19 in einen radial schräg nach innen verlaufenden Ringabschnitt 24 über. Die verbleibende zentrale Öffnung im Grundkörper 4 ist mit einem auf den Ringabschnitt 24 aufgeschnappten Deckel 25 auf Kunststoff verschlossen. Das Wälzlager 3 ist damit zur Stirnfläche 17 hin abgedichtet. Auf der gegenüberliegenden, dem Befestigungsende 18 zugewandten Seite ist ein Dichtring 26 zwischen dem Innenring 6 und dem Außenring 7 angeordnet. Eine zusätzliche Schutzfunktion ist durch den anschlussseitigen Winkelring 16 gegeben. Es ist damit keine Abdichtung erforderlich, welche die Verkippung zwischen dem Außenring 7 und Hülsenabschnitt 19 einerseits und der Tragachse 2 andererseits ausgleicht. Die Andruckrolle 1 nach den
