Spindel, insbesondere für TextilmaschinenSpindles, in particular for textile machines
Gegenstand der Erfindung ist eine Hochgeschwindigkeitsspindel, welche besonders für Textilmaschinen geeignet ist. In der Arbeitsstellung wird die Spindel in einer bestimmten Axiallage gesichert, wobei es von Wichtigkeit ist, ein Durchdrehen der Buchse in radialer Richtung zu verhindern. Mit Rücksicht auf einen eventuellen mehrfachen Ausbau der Spindel während ihrer gesamten Lebensdauer, insbesondere während der Reinigung von Maschinenelementen, wählt man bei Textilmaschinen für Spindellagerungen den Schiebesitz, wobei das Durchdrehen der Spindel durch Druck einer einfachen Anpress-Scliraube ver-The subject of the invention is a high-speed spindle, which is particularly suitable for textile machines. In the working position, the spindle is in a certain axial position secured, whereby it is important to rotate the bushing in the radial direction impede. In consideration of a possible multiple dismantling of the spindle during its entire service life, Particularly during the cleaning of machine elements, spindle bearings are chosen for textile machines the sliding seat, whereby the turning of the spindle is prevented by pressing a simple pressure screw

hindert wird, die sich, gegen den Spindelkörper von außen stützt. Die richtige Funktionsweise der Spindel sowie ihre garantierte Lebensdauer wird durch diese Fixierungsart unkontrollierbar herabgesetzt, und zwar aufgrund der Verformung der Buchse durch Druck dieser Anpress-Schraube. Dies hat außer der Herabsetzung der Lebensdauer eine Geräuscherhöhung der Lagerung zur Folge, was bei einer großen Anzahl von Arbeitsplätzen, wie dies namentlich bei Textilmaschinen der Fall ist, die Arbeitsbedingungen erheblich verschlechtert.is prevented, which is against the spindle body from the outside supports. The correct functioning of the spindle as well as its guaranteed service life is uncontrollably reduced by this type of fixation, due to the Deformation of the bushing due to pressure from this pressure screw. In addition to reducing the service life, this results in an increase in the noise of the storage, which in a large number of jobs, as is the case in particular with textile machines, the working conditions considerably worsened.
Die Erfindung vermeidet diese Nachteile. Die Spindel besteht aus der Spindelbuchse, in welcher die" Welle in einem Lagerpaar gelagert ist. Das Prinzip der Erfindung beruht darauf, daß am umfang bzw. wenigstens an einem Teil des Umfangs der Spindelbuchse eine Nut für die Aufnahme eines geteilten kreis- bzw. segmentförmigen elastischen Spannelementes.ausgebildet ist, auf welchem von oben eine in den Halter der Spindelbuchse eingeschraubte Anpress-Sehraube aufsitzt. Auf den Seitenflächen des eingelegten Spannelementes sind wechselweise gegeneinander orientierte Durchbrüche und VorSprünge ausgebildet. Die Anpress-Schraube ist auf ihrer Abstützfläche mit einer scharfen Spitze versehen. Am Umfang der Spindelbuchse bzw. in der Bohrung des Halters dieser Buchse ist eine zweite Wut ausgebildet, ,in der ein elastischer Ring gelagert ist.The invention avoids these disadvantages. The spindle exists from the spindle bushing in which the "shaft" is mounted in a pair of bearings. The principle of the invention is based on the fact that on the circumference or at least on part of the circumference of the spindle bushing a groove for the recording a divided circular or segment-shaped elastic Spannelementes. Is formed on which from above a pressure viewing hood screwed into the holder of the spindle bushing sits on. On the side surfaces of the inserted clamping element are alternately against each other oriented breakthroughs and protrusions formed. The pressure screw is on its support surface with a sharp point. On the circumference of the spindle bushing or in the bore of the holder of this bushing is a second fury formed, in which an elastic ring is stored is.
Das Wesen der Erfindung ist anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:The essence of the invention is explained in more detail using an exemplary embodiment shown schematically in the drawing. Show it:

Die Spindel in Fig. 1a besteht aus der Spindelbuohse 1 · mit Laufbahnen 1a für den Kugelsatζ 1b, in welcher die Welle 1o gelagert ist. Auf der Spindelbuchse 1, welche in die Bohrung des Halters 2 geschoben ist, befindet sich eine geeignet ausgebildete Umfangsnut 3, in der ein elastisches Spannelement 3a eingesetzt ist, welches im Prinzip ein geteilter Ring aus Kunststoff bzw. aus sonstigem elastischem Werkstoff ist. Das Befestigen der Spindelbuchse 1 im Halter erfolgt mittels der Anpress-Schraube 4» welche an ihrem Ende mit einer scharfen Spitze 5 versehen ist. Durch Anziehen der Anpress-Schraube 4 dringt die Spitze mit minimaler Radialkraft in das Spannelement 3a ein und hält dieses in eingestellter Axiallage fest. Die einwirkende Radialkraft verursacht keine Verformung der Laufbahn 1a in der Spindelbuchse 1, Die Nut 5y deren Grund entweder flach, konkav oder anders ausgebildet ist, verläuft Über den ganzen Umfang der .33uchse 1 oder auf dessen einem Teil. ';.'"'■'■ The spindle in Fig. 1a consists of the spindle sleeve 1 · with raceways 1a for the Kugelsatζ 1b, in which the shaft 1o is mounted. On the spindle sleeve 1, which is pushed into the bore of the holder 2, there is a suitably designed circumferential groove 3 in which an elastic clamping element 3a is inserted, which is in principle a split ring made of plastic or other elastic material. The spindle bushing 1 is fastened in the holder by means of the pressure screw 4, which is provided with a sharp point 5 at its end. By tightening the pressure screw 4, the tip penetrates the clamping element 3a with minimal radial force and holds it in the set axial position. The acting radial force does not cause any deformation of the raceway 1a in the spindle bushing 1. The groove 5y, the base of which is either flat, concave or otherwise, runs over the entire circumference of the .33uchse 1 or on one part of it. ';.'"'■' ■
Das Spannelement 3a ist geschlitzt bzw. anders gestaltet und "ist in die Hut 3 geschoben. Pur die Behebung des Axialspiels ist dieses Spannelement zweckmäßig gestaltet und aus einem entsprechend elastischen Werkstoff hergestellt,The clamping element 3a is slotted or designed differently and "is pushed into the hat 3. Pur the elimination of the Axial play, this clamping element is designed appropriately and made of a correspondingly elastic material,

Auf den Seitenflächen des Spannelementes 3a, wie dies aus dem Detail in Fig. 1b zu entnehmen ist, sind Durchbräche 7 mit gegenüberliegenden Vorsprüngen 3 ausgebildet, die eine elastische Durchbiegung und somit eine !Behebung des Axialspiels des Spannelementes 3a in der Nut 3 der Buchse 1 gesta.tten.On the side surfaces of the tensioning element 3a, as can be seen from the detail in FIG. 1b, there are openings 7 formed with opposing projections 3, an elastic deflection and thus an elimination of the axial play of the clamping element 3a in the groove 3 of the Socket 1 allowed.
Die Spindel in Fig. 2'ist auf dieselbe Art gelöst wie die vorher beschriebene; sie ist jedoch mit einem Ring 6a aus elastischem Werkstoff versehen, welcher in der zweiten Nut 6, die an die Nut 3 für die Aufnahme des Spannelementes 3a grenzt, untergebracht ist. Dieser elastische Ring 6a sichert die Spindel im Halter gegen Drehung und Schwingungen. Er ermöglicht gleichzeitig eine gute Positionierung der Spindel während ihres Einbaues.The spindle in Fig. 2 'is solved in the same way as that previously described; However, it is provided with a ring 6 a made of elastic material, which in the second Groove 6, which is attached to the groove 3 for receiving the clamping element 3a borders, is housed. This elastic ring 6a secures the spindle in the holder against rotation and Vibrations. At the same time, it enables the spindle to be well positioned during installation.
