Die vorliegende Erfindung betrifft einen Zwirnflügel gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a twisting wing according to the preamble of claim 1.

Als nachteilig erweist sich, dass die gemäß dem Stand der Technik befestigte ferromagnetische Scheibe beziehungsweise Magnetscheibe zu Wartungszwecken nicht zerstörungsfrei vom Spindelschaft beziehungsweise von der Trägerplatte lösbar ist.A disadvantage proves that the fixed according to the prior art ferromagnetic disk or Magnetic disk for maintenance purposes not destructive from the spindle shaft or from the support plate is solvable.
Der Erfindung liegt somit die Aufgabe zugrunde, einen Zwirnflügel bereitzustellen, der wartungsfreundlicher ist.The invention is therefore based on the object to provide a twisting wing, which is easier to maintain.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Gemäß Anspruch 1 wird vorgeschlagen, dass die Verbindungselemente als Schnappelemente ausgeführt sind. Dies hat den Vorteil, dass die Hysteresescheibe auf einfache Weise durch Fügen zu montieren ist, wobei auf Grund des zwischen den Schnappelementen und der Hysteresescheibe bestehenden Kraftformschlusses diese gegen ein unbeabsichtigtes Herausfallen aus der Drehbuchse gesichert ist. Die erfindungemäß verwendete Schnappverbindung ist eine äußerst werkstoffgerechte, montage- und demontagefreundliche Verbindungsart, sodass die Montage und Demontage der Zwirnspindel zu Wartungszwecken vereinfacht wird. Insbesondere ermöglicht die Schnappverbindung ein zerstörungsfreies Ablösen der Hysteresescheibe von der Drehbuchse. Durch die Ausgestaltung der Schnappelemente als integrierte Bestandteile der Drehbuchse wird deren Herstellung vereinfacht und somit kostengünstiger. Die Integration der Schnappelemente als Bestandteil der Drehbuchse erfolgt durch Spritzgießen als kostengünstiges und geeignetes Herstellungsverfahren.According to claim 1, it is proposed that the connecting elements are designed as snap elements. This has the advantage that the hysteresis disc is easy to assemble by joining, which is secured against accidental falling out of the rotary bushing due to the existing between the snap elements and the hysteresis force-fit. The snap connection used in accordance with the invention is an extremely material-compatible, easy to assemble and disassemble connection, so that the assembly and disassembly of the twisting spindle is simplified for maintenance purposes. In particular, the snap connection allows a non-destructive detachment of the hysteresis disc from the rotary sleeve. Due to the design of the snap elements as integrated components of the rotary socket whose production is simplified and thus more cost effective. The integration of the snap elements as part of the rotary socket is carried out by injection molding as a cost effective and suitable manufacturing process.
Insbesondere können die Schnappelemente geschlitzt ausgebildet sind, einen im Wesentlichen ringförmigen Querschnitt aufweisen und mit endseitig sich radial nach außen erstreckenden Vorsprüngen versehen sein, die die Hysteresescheibe abschnittsweise hintergreifen. Dabei wird durch die die Öffnungen der Hysteresescheibe in axialer Richtung durchdringenden Schnappelemente eine radiale Fixierung der Hysteresescheibe bewirkt. Mittels der die Hysteresescheibe abschnittsweise hintergreifenden Vorsprünge, die als für die Schnappverbindung erforderlichen Hinterschneidungen der Schnappelemente ausgebildet sind, wird außerdem eine axiale Fixierung der Hysteresescheibe erreicht. Ein weiterer Vorteil besteht darin, dass im Gegensatz zur Verwendung von metallischen Schrauben, die beispielsweise zur lösbaren Verbindung der Hysteresescheibe mit der Drehbuchse verwendet werden könnten, die erfindungsgemäße Verbindungsart keinen Einfluss auf das Magnetfeld ausübt.In particular, the snap elements may be formed slotted, have a substantially annular cross-section and be provided with end radially outwardly extending projections, which are the hysteresis disc engage in sections. In this case, a radial fixation of the hysteresis disc is effected by the openings of the hysteresis disc in the axial direction penetrating snap elements. By means of the hysteresis disc sections engaging behind projections which are formed as required for the snap connection undercuts of the snap elements, also an axial fixation of the hysteresis disc is achieved. Another advantage is that, in contrast to the use of metallic screws, which could be used for example for releasably connecting the hysteresis disc with the rotary sleeve, the compound according to the invention has no influence on the magnetic field.
Vorteilhafterweise können die Vorsprünge sich in axialer Richtung verjüngend ausgebildet sein. Die sich verjüngende Ausbildung der an den Schnappelementen endseitig angeordneten Vorsprünge in Richtung des von der Drehbuchse abgewandten Endes der Schnappelemente hat den Vorteil, dass die Schnappelemente bei der Anordnung der Hysteresescheibe an der Drehbuchse leichter durch die Durchbohrungen auf der Hysteresescheibe hindurchgeführt werden können.Advantageously, the projections may be tapered in the axial direction. The tapered design of the end elements arranged on the snap elements projections in the direction of the end facing away from the rotary sleeve end of the snap elements has the advantage that the snap elements can be easily passed through the holes on the hysteresis disc in the arrangement of the hysteresis disc on the rotary sleeve.
Des Weiteren können die Schnappelemente um einen Winkel zwischen 30° und 120° versetzt zueinander in Umfangsrichtung der Drehbuchse angeordnet sein. Vorzugsweise kann eine um 90° zueinander versetzte Anordnung der Schnappelemente vorgesehen sein.Furthermore, the snap elements can be arranged offset by an angle between 30 ° and 120 ° to each other in the circumferential direction of the rotary bushing. Preferably, a mutually offset by 90 ° arrangement of the snap elements may be provided.
Insbesondere kann auf der Traghülse ein Wälzlager angeordnet sein, an dessen Außenring die Drehbuchse durch eine Schnappverbindung kraftformschlüssig angeordnet ist und an dessen Innenring eine Einstellbuchse kraftschlüssig mit dem Wälzlager verbunden ist. Des Weiteren kann die Einstellbuchse einen Nocken aufweisen, der in einer auf der Traghülse in Umfangsrichtung verlaufenden, ansteigenden Nut geführt wird. Die Einstellbuchse dient dabei der Einstellbarkeit eines zu übertragenden Bremsmomentes, dessen Größe stufenweise innerhalb eines definierten Bereiches einstellbar ist. Dabei können zur Sicherung einer Raststellung eine an der Trägerhülse angeordnete Stellungsverzahnung sowie ein an der Drehbuchse angeordneter Rastnocken vorgesehen sein. Durch das formschlüssige in Eingriff bringen der Stellungsverzahnung und des Rastnocken wird das voreingestellte Bremsmoment festgelegt.In particular, can be arranged on the support sleeve, a rolling bearing, on the outer ring, the rotary sleeve is frictionally arranged by a snap-fit connection and on the inner ring a setting bush is non-positively connected to the rolling bearing. Furthermore, the adjusting bushing have a cam which is guided in a running on the support sleeve in the circumferential direction, rising groove. The adjusting bush serves for the adjustability of a braking torque to be transmitted, the size of which is adjustable stepwise within a defined range. It can be provided to secure a detent position arranged on the support sleeve positional teeth and arranged on the rotary bushing locking cam. The pre-set braking torque is determined by the positive engagement of the positional toothing and the locking cam.

Die Einstellbuchse 9 wird auf der Traghülse 3 mittels eines Nocken 11 geführt, der in einer um die Traghülse 3 umlaufend angeordneten Nut 12 eingreift. Dies dient der Einstellbarkeit des zu übertragenden Bremsmomentes. Die Einstellbarkeit des Bremsmomentes wird dadurch erreicht, dass ein zwischen der Hysteresescheibe 7 und den Polmagneten 5 befindlicher Luftspalt 15 durch das Drehen der Einstellbuchse 9 in seiner Größe variiert wird. Hierzu weist die Nut 12 einen in Umfangsrichtung der Traghülse 13 ansteigenden Verlauf auf, sodass die Polmagnete 5 und die Hysteresescheibe 7 aufeinander zu oder von einander weg bewegt werden können. Die Sicherung der Raststellung wird durch eine an der Trägerhülse 3 angeordnete Stellverzahnung 14 in Verbindung mit einem an der Drehbuchse 6 angeordneten Rastnocken 13 erreicht.The adjusting bushing 9 is guided on the
Um eine sichere Befestigung der Hysteresescheibe 7 an der Drehbuchse 6 zu erreichen, wird die Hysteresescheibe 7 durch eine Schnappverbindung mit der Drehbuchse 6 verbunden. Hierzu sind an der Drehbuchse 6 sich koaxial zur Längsachse des Fadeneinlaufrohres 2 erstreckende, zylindrische, geschlitzte Schnappelemente 10 angeordnet, die der Aufnahme der Hysteresescheibe 7 dienen, wie in
Die Schnappelemente 10 sind gleichmäßig in Umfangsrichtung der Drehbuchse 6 auf der der Hysteresescheibe 7 zugewandten Seite unter einem Winkel von 30° bis 120°, vorzugsweise 90°, versetzt zueinander angeordnet. Die Hysteresescheibe 7 weist der Anordnung der Schnappelemente 10 entsprechende Durchbohrungen 16 auf, die der formschlüssigen Aufnahme der Schnappelemente 10 beim Aufclipsen der Hysteresescheibe 7 auf die Drehbuchse 6 dienen.The
Durch die Schnappelemente 10 wird eine zusätzliche radiale Fixierung in aufgeclipster Position der Hysteresescheibe 7 erreicht. Zur axialen Fixierung weisen die Schnappelemente 10 endseitig sich in radialer Richtung nach außen ersteckende Vorsprünge 17 auf, die die Hysteresescheibe 7 in auf die Drehbuchse 6 aufgebrachter Position abschnittsweise hintergreifen.By the
Bei Schnappverbindungen ist es erforderlich, während des Fügevorganges einen Hinterschnitt zu überwinden. Vorliegend handelt es sich dabei um die Vorsprünge 17. Zur Aufbringung der Hysteresescheibe auf die Drehbuchse 6 weisen die geschlitzten Schnappelemente 10 jeweils im Winkel von cirka 90° versetzt zueinander angeordnete Längsschlitze 18 auf, die die Schnappelemente 10 segmentieren. Beim Aufdrücken der Hysteresescheibe 7 auf die Drehbuchse 6 werden die segmentierten Schnappelemente 10 jeweils zusammengepresst, um mit Erreichen einer Endposition, in der die Hysteresescheibe 7 an der Drehbuchse 6 flächig anliegt, wieder auseinander zu spreizen, sodass die Vorsprünge 17 der Schnappelemente 10 die Hysteresescheibe 7 abschnittsweise hintergreifen.With snap connections, it is necessary to overcome an undercut during the joining process. In the present case, these are the
