Die Erfindung betrifft ein Verfahren zur Herstellung eines Ringläufers für Ringspinn- oder Ringzwirnmaschinen sowie sowie einen Ringläufer nach Anspruch 1 bzw. 7.The invention relates to a method for manufacturing a ring traveler for ring spinning or ring twisting machines as well as a ring traveler according to claim 1 or 7.

Ringläufer von Ringspinn- und Ringzwirnmaschinen werden mit hoher Umlaufgeschwindigkeit (30m/s bis 50m/s) auf Ringen der entsprechenden Ringspinn- oder Ringzwirnmaschinen bewegt. Sowohl die Kontaktfläche zwischen Ringläufer und Ring als auch die Kontaktfläche zwischen Ringläufer und Faden sind einem hohen Verschleiss unterworfen. Zur Produktionssteigerung werden jedoch zunehmend höhere Laufgeschwindigkeiten der Ringläufer gefordert. Durch Erreichen höherer Standzeiten sollen gleichzeitig die Kosten gesenkt werden.Ring travelers of ring spinning and ring twisting machines with high circulation speed (30m / s to 50m / s) Wrestling of the corresponding ring spinning or ring twisting machines emotional. Both the contact area between Ring traveler and ring as well as the contact area between Ring traveler and thread are subject to high wear subjected. However, to increase production increasingly higher speeds of the ring travelers required. By achieving a longer service life at the same time the costs are reduced.

Durch Beschichtung der Ringläufer mit entsprechenden Materialien konnten deren Lauf- und Betriebseigenschaften in den letzten Jahren deutlich verbessert werden. Die Verschleissfestigkeit am Fadendurchgang konnte bisher jedoch nicht verbessert werden.By coating the ring traveler with appropriate Materials could change their running and operating properties have improved significantly in recent years. The So far, wear resistance at the thread passage could however, cannot be improved.

Aus U.S. Patent 4,677,817 ist ein Ringläufer bekannt, der eine Keramikschicht aufweist, die dem Ringläufer eine höhere Härte sowie verbesserte Wärme- und Korrosionsresistenz verleiht. Dieser bekannte Ringläufer weist aufgrund der verbesserten Lauf- und Betriebseigenschaften deutlich reduzierte Betriebskosten auf. Negativ beeinflusst wird die Kostenrechnung jedoch durch den relativ hohen Herstellungsaufwand.From U.S. Patent 4,677,817 a ring traveler is known which has a ceramic layer that the ring traveler higher hardness and improved heat and corrosion resistance gives. This well-known ring traveler has due to the improved running and operating characteristics significantly reduced operating costs. Negatively influenced However, the cost accounting is relative high manufacturing costs.

Aufgabe der vorliegenden Erfindung ist es daher, einen Ringläufer für Ringspinn- oder Ringzwirnmaschinen zu schaffen, der einerseits weiter verbesserte Lauf- und Betriebseigenschaften aufweist und andererseits mit reduziertem Aufwand herstellbar ist. Ferner ist ein Verfahren zur Herstellung dieses Ringläufers anzugeben. The object of the present invention is therefore a Ring traveler for ring spinning or ring twisting machines create the one hand further improved running and Has operating properties and on the other hand with reduced Effort can be produced. It is also a procedure to specify for the production of this ring traveler.

Die Lösung dieser Aufgabe gelingt mit einem Verfahren und einem Ringläufer, welche die in Anspruch 1 bzw. Anspruch 7 angegebenen Merkmale aufweisen.This problem can be solved with a method and a ring traveler, which in claim 1 or claim 7 specified features.

Ein erfindungsgemässer Ringläufer weist einen aus Eisenwerkstoff bestehenden, nicht beschichteten Kern auf, der zumindest im Bereich der Laufflächen, mit denen er auf einem Ring einer Ringspinn- oder Ringzwirnmaschine gleitet oder in denen der Faden geführt ist, eine gegebenenfalls mehrteilige nitrierte Randschicht aufweist.A ring traveler according to the invention has one made of iron material existing, uncoated core on the at least in the area of the treads with which he is on a ring of a ring spinning or ring twisting machine slides or in which the thread is guided, one if necessary has multi-part nitrided surface layer.

Anstatt mit erheblichem Aufwand eine Schicht, z.B. eine Keramik- oder Phosphatschicht, auf den Kern aufzubringen und gegebenenfalls nachzubearbeiten, wird dieser zumindest teilweise einer Nitrierbehandlung unterworfen, während der dem Kern Wärmeenergie sowie ein Nitriermittel als Wirkmedium zugeführt wird.Instead of one shift with considerable effort, e.g. a Ceramic or phosphate layer to apply to the core and postprocessing if necessary, this will at least partially subjected to nitriding treatment, while the core has thermal energy as well as a nitrating agent is supplied as the active medium.

Bei einer Nitrierbehandlung kann bekanntlich eine Versprödung sowie eine erhebliche Reduktion der Elastizität des behandelten Materials auftreten. Durch erfindungsgemässe Steuerung der Zusammensetzung des Nitriermittels und entsprechend gewählte Behandlungszeit kann die Elastizität des Ringläufers erhalten werden, die erforderlich ist, um diesen verformungsfrei auf Spinnringe aufsetzen zu können.In the case of a nitriding treatment, it is known that one Embrittlement as well as a significant reduction in Elasticity of the treated material occur. By control of the composition of the Nitrating agent and the chosen treatment time can be obtained the elasticity of the ring traveler, the is necessary to keep this on deformation-free To be able to put on spinning rings.

Der Kern wird auf eine Temperatur im Bereich von 450°C - 600°C, vorzugsweise auf eine Temperatur nahe 550°C erwärmt und während 3 - 60 Stunden, vorzugsweise während etwa 24 Stunden, in dem genannten Temperaturbereich gehalten. Das Nitriermittel kann in Form eines vorzugsweise aus NH3- und N2-Teilen bestehenden Gases, einer Flüssigkeit oder eines Plasmas zugeführt werden. Bereiche, in denen keine Nitrierbehandlung erfolgen soll, werden z.B. abgedeckt.The core is heated to a temperature in the range from 450.degree. C. to 600.degree. C., preferably to a temperature close to 550.degree. C., and is kept in the temperature range mentioned for 3 to 60 hours, preferably for about 24 hours. The nitrating agent can be supplied in the form of a gas, a liquid or a plasma, preferably consisting of NH 3 and N 2 parts. Areas in which no nitriding treatment should take place are covered, for example.

Die nitrierte Randschicht des Ringläuferkerns besteht aus einer Verbindungsschicht ohne zusätzliche Diffusionsschicht, aus einer Verbindungsschicht mit zusätzlicher, radial innen liegender Diffusionsschicht oder nur aus einer Diffusionsschicht. Die Verbindungsschicht weist vorzugsweise eine Dicke von 0,1 µm - 30 µm und die Diffusionsschicht eine Dicke von 1 µm - 2000 µm auf.The nitrided edge layer of the ring rotor core consists of a connection layer without an additional diffusion layer, from a connection layer with additional, radially inner diffusion layer or only a diffusion layer. The connection layer points preferably a thickness of 0.1 microns - 30 microns and the Diffusion layer to a thickness of 1 µm - 2000 µm.

Vorzugsweise weist das Wirkmedium, zusätzlich zu den Stickstoffteilen, Schwefel- und/oder Kohlenstoffteile auf. Durch Beimischung von Schwefel- und/oder Kohlenstoffteilen kann der Reibwert reduziert werden. Gleichzeitig können die Dicken der Verbindungsschicht und der Diffusionsschicht nach Bedarf abgestimmt werden.The active medium preferably has, in addition to Nitrogen parts, sulfur and / or carbon parts on. By adding sulfur and / or carbon parts the coefficient of friction can be reduced. At the same time, the thicknesses of the connection layer and the diffusion layer can be matched as required.

Bei der Wahl von geringen Dicken der Verbindungsschicht ergeben sich nur geringe Veränderungen der Rauheit der Kernoberfläche.When choosing small thicknesses of the connection layer there are only slight changes in the roughness of the Core surface.

In vorzugsweisen Ausgestaltungen der Erfindung wird die Oberfläche des Ringläufers vor und/oder nach der Nitrierbehandlung zusätzlich poliert. Ringläufer, die einer hohen chemischen Beanspruchung ausgesetzt sind, werden vorzugsweise nachoxydiert.In preferred embodiments of the invention, the Surface of the ring traveler before and / or after the Nitriding treatment additionally polished. Ring traveler that are exposed to high chemical stress, are preferably post-oxidized.

Sofern ein Kern aus einem vergüteten Stahl verwendet wird, entstehen während der Nitrierbehandlung nur vernachlässigbar kleine Massänderungen.If a core made of tempered steel is used will only arise during the nitriding treatment negligible small size changes.

Die erfindungsgemässen Ringläufer weisen wesentlich verbesserte Betriebseigenschaften, insbesondere eine erhöhte Läuferstandzeit sowie eine erhöhte Einschneideresistenz an der Fadenpassage auf. Die funktionell sehr wichtige Einschneideresistenz im Fadendurchgang bei mechanischer und/oder chemischer Belastung wurde um 50% - 200% verbessert, woraus ein Verbesserung der Qualität des verarbeiteten Garns resultiert. Aufgrund der erhöhten chemischen Resistenz werden ferner Garnverschmutzungen durch Korrosionsprodukte vermieden, die bei der Verarbeitung avivierter und chlorhaltiger Fasern bisher auftraten. Aufgrund der guten Gleiteigenschaften wird zudem keine oder nur eine geringe Faserschmierung benötigt. The ring travelers according to the invention have significantly improved Operating characteristics, especially an increased one Runner service life and increased resistance to cutting at the thread passage. The functionally very important Resistance to cutting in the thread passage with mechanical and / or chemical exposure was increased by 50% - 200% improved, resulting in an improvement in the quality of the processed yarn results. Because of the increased chemical resistance will also contaminate yarn avoided by corrosion products during processing previously developed and chlorine-containing fibers have so far occurred. Due to the good sliding properties, it is also little or no fiber lubrication required.

Die Ringläufer können zudem mit geringerem Aufwand hergestellt und gegebenenfalls vorhandenen individuellen Anforderungen angepasst werden.The ring traveler can also be done with less effort manufactured and possibly existing individual Requirements are adjusted.

Erfindungsgemässe Ringläufer können sowohl in Spinnereien als auch in Zwirnereien verwendet werden. Ihre guten Laufeigenschaften, wie z.B. gutes Gleiten und geringer Verschleiss, kommen besonders vorteilhaft im Zusammenwirken mit Stahlringen zur Geltung, sie können aber auch auf anderen Ringen, wie z.B. auf gesinterten, brünierten oder beschichteten Ringen verwendet werden.Ring travelers according to the invention can be used in spinning mills as well as used in twisting factories.

Fig. 4 zeigt einen Schnitt durch den Kern 20b eines intensiver behandelten Ringläufers 10, der eine Verbindungsschicht 23 und darunter eine weitere aus nitriertem Grundwerkstoff bestehende Schicht aufweist, die als Diffusionsschicht 24 bezeichnet wird. In der Diffusionsschicht 24 sind stickstoffangereicherte Mischkristalle und ausgeschiedene Nitride enthalten.Fig. 4 shows a section through the core 20b intensively treated ring traveler 10, which is a connection layer 23 and another one made of nitrided Base material existing layer, which as Diffusion layer 24 is referred to. In the diffusion layer 24 are nitrogen-enriched mixed crystals and contain excreted nitrides.

Fig. 5 zeigt einen Schnitt durch den Kern 20c eines behandelten Ringläufers 10 der lediglich eine Diffusionsschicht 24 und keine Verbindungsschicht 23 aufweisen.Fig. 5 shows a section through the core 20c treated ring traveler 10 of only one diffusion layer 24 and have no connection layer 23.

Die Wahl des Schichtaufbaus erfolgt nach Anforderungsprofil für den Ringläufer 10. Für Ringläufer 10 mit hohen Laufgeschwindigkeiten wird vorzugsweise eine harte Verbindungsschicht vorgesehen. Für Ringläufer 10, die relativ hohen Kräften ausgesetzt sind, wird, unter Vermeidung einer Verbindungsschicht, vorzugsweise nur eine zähere und trotzdem relativ harte Diffusionsschicht 24 gewählt.The choice of layer structure is made according to the requirement profile for ring traveler 10. For ring traveler 10 with high Running speeds will preferably be a hard tie layer intended. For ring travelers 10 who are subjected to relatively high forces, under Avoiding a connection layer, preferably only a tougher, yet relatively hard diffusion layer 24 chosen.

Die Verbindungsschicht weist vorzugsweise eine Dicke von 0,1 µm - 30 µm und die Diffusionsschicht eine Dicke von 1 µm - 2'000 µm auf. Besonders vorteilhaft ist die Verwendung einer Verbindungsschicht mit einer Dicke von 8 µm - 12 µm und eine Diffusionsschicht mit einer Dicke von 100 µm - 200 µm. Durch die Wahl einer geringen Dicke oder der gänzlichen Vermeidung der Verbindungsschicht können Materialbrüche verhindert werden, die bisher den Einsatz dieser Technologie in diesem Bereich unmöglich gemacht haben.The connecting layer preferably has a thickness of 0.1 µm - 30 µm and the diffusion layer has a thickness of 1 µm - 2,000 µm. This is particularly advantageous Use a tie layer with a thickness of 8 µm - 12 µm and a diffusion layer with a thickness of 100 µm - 200 µm. By choosing a small thickness or completely avoiding the connection layer Material breaks can be prevented, which have been used so far made this technology impossible in this area to have.

Die durch die Nitrierbehandlung entstehenden Schichtdicken sind stark von der Stahlzusammensetzung und vom Oberflächenzustand der unbehandelten Ringläufer 10 abhängig. Grundsätzlich wird bei hohem Stickstoffangebot und hohen Temperaturen eine grosse Verbindungsschicht und bei niedrigem Stickstoffangebot und tiefen Temperaturen eine dünne Verbindungsschicht erzielt. Die Schichtdicken bzw. die Diffusionstiefen sind dabei abhängig von der Behandlungsdauer.The layer thicknesses resulting from the nitriding treatment are strong in steel composition and Surface condition of the untreated ring travelers 10 dependent. Basically, when there is a high nitrogen supply and high temperatures a large connection layer and with low nitrogen supply and low temperatures achieved a thin connection layer. The layer thicknesses or the diffusion depths depend on the Treatment duration.

Feine, leichte Ringläufer 10 werden zudem während einer kürzeren Dauer behandelt als grobe, schwere Ringläufer 10.Fine, light ring travelers 10 are also during a shorter duration treated as coarse, heavy ring travelers 10th

Durch Beimischung von Schwefel- und/oder Kohlenstoffteilen kann der Reibwert reduziert werden. Gleichzeitig können die Dicken der Verbindungsschicht und der Diffusionsschicht nach Bedarf abgestimmt werden.By adding sulfur and / or carbon parts the coefficient of friction can be reduced. simultaneously can the thickness of the tie layer and the Diffusion layer can be tailored as needed.

Bei der Wahl von geringen Dicken der Verbindungsschicht ergeben sich nur geringe Veränderungen der Rauheit der Kernoberfläche 22a, so dass ein anschliessendes Polieren der Laufflächen vermieden werden kann. Ferner wird eine Versprödung des Kernwerkstoffes vermieden.When choosing small thicknesses of the connection layer there are only slight changes in the roughness of the Core surface 22a, so that a subsequent polishing the treads can be avoided. Furthermore, a Embrittlement of the core material avoided.

Zur Optimierung des Ringläufers 10 wird in vorzugsweisen Ausgestaltungen der Erfindung die Oberfläche 22; 22a des Kerns 20; 20a vor und/oder nach der Nitrierbehandlung poliert.To optimize the ring traveler 10 is preferred Embodiments of the invention, the surface 22; 22a of the Core 20; 20a before and / or after the nitriding treatment polished.

Ringläufer 10, die einer hohen chemischen Beanspruchung ausgesetzt sind, werden vorzugsweise nachoxydiert.Ring traveler 10, which has a high chemical stress are preferably post-oxidized.

Im Bereich der Lauffläche 1 muss natürlich vornehmlich eine mit 3 bezeichnete Innenseite des Ringläufers 10 verschleissfest und mit guten Gleiteigenschaften ausgestattet sein und daher eine nitrierte Schicht 23; 24 aufweisen. Bei entsprechender Fadenspannung kann es sich ergeben, dass der Ringläufer 10 seitlich verkippt auf einem Ring entlang läuft, so dass es sich als vorteilhaft erweisen kann, auch die beiden Stirnseiten 2 mit einer nitrierten Schicht 23; 24 zu versehen.In the area of the tread 1, of course, primarily an inside of the ring traveler 10 designated by 3 wear-resistant and equipped with good sliding properties be and therefore a nitrided layer 23; 24 exhibit. With appropriate thread tension, it can reveal that the ring traveler 10 tilts laterally runs along a ring, so it turns out to be beneficial can also prove the two end faces 2 with one nitrided layer 23; 24 to be provided.

Die Nitrierbehandlung erfolgt vorzugsweise für den gesamten Ringläufer 10, obwohl es auch möglich ist, nur die mechanisch und/oder chemisch stark beanspruchten Bereiche mit einer nitrierten Randzone zu versehen.The nitriding treatment is preferably carried out for the entire ring traveler 10, although it is also possible, only the mechanically and / or chemically stressed To provide areas with a nitrided edge zone.
