Description
Die Erfindung betrifft einen Spinnring für eine Ringspinnmaschine, in der eine Anzahl von Spinnringen mit Läufern zum Aufwickeln von Fäden verwendet wird.
Bei der Entwicklung von Spinnringen geht es neben der Verbesserung der Form um eine Steigerung der Verschleissfestigkeit der Oberfläche, eine Verkürzung der Einlaufzeit und Verbilligung des Produkts durch Wahl von preiswertem Grundmaterial und/oder durch kostengünstige Herstellung. Üblicherweise wird heute gehärteter Kugellagerstahl oder einsatzgehärteter Stahl als Grundmaterial eingesetzt. Kostengünstiger wären andere Legierungen wie zum Beispiel auf Aluminium-, Magnesium- oder Zink-Basis. Besonders preiswert ist die Herstellung aus Kunststoff, wobei letzterer mit Füllstoffen oder Fasern verstärkt sein kann.
Der Verschleissmechanismus hängt u.a. vom Wechselspiel zwischen Spinnring und dem von ihm geführten Läufer ab. Wenn die Oberfläche des Spinnrings einmal Schädigungen aufweist, führt dies zu einer Beeinträchtigung der Stabilität des Läufers auf seiner Bahn und zu einer erhöhten Flächenbelastung an der Kontaktstelle Ring-Läufer, wodurch es punktuell zu Spitzenbeanspruchungen am Spinnring mit verstärktem Verschleiss kommt. Andererseits wird der Läufer dabei rasch soweit geschädigt, dass er durch einen neuen ersetzt werden muss.
Bei der Oberflächenbehandlung des Spinnrings bietet sich die Beschichtungstechnik an, wobei Nikkel-Phosphor-Legierungen, vorzugsweise in Bädern, auf die Lauffläche des Spinnrings aufgebracht werden.
Das Problem einer solchen Nickel-Phosphor-Schicht, zum Beispiel Nickel-Phosphor mit 8-10% Phosphor, liegt darin, dass sie zur Erzielung einer ausreichend hohen Härte bei mindestens 300-400 DEG C angelassen werden muss (Fig. 1). Diese hohe Anlasstemperatur liegt für zahlreiche Grundwerkstoffe auf Aluminium-, Magnesium- oder Zinkbasis oder aus Kunststoff zu hoch, da Verzunderung, Verzug oder Anschmelzen die Folge sein können.
Es ist Ziel der vorliegenden Erfindung, die Beschichtung so zu verbessern, dass auch auf preiswerten Grundwerkstoffen wie Aluminium-, Magnesium- und Zink-Legierungen oder Kunststoffen eine gute Abrasionsfestigkeit der Schicht bei tiefer Anlasstemperatur oder ohne Anlassen erreicht wird.
Diese Aufgabe wird durch eine Metall-Phosphor-Schicht zumindest an der Lauffläche des Spinnringes gelöst, die mit dem Läufer in Berührung kommt, mit einem Anteil von 1-4% Phosphor oder 0.5-4% Bor. Eine Anlasstemperatur im Bereich unter 250 DEG C genügt bei Metall-Phosphor-Legierungen, um eine hohe Schichthärte über 750 HV zu erhalten. Bei Metall-Bor-Legierungen kann auf ein Anlassen u.U. völlig verzichtet werden. Als Metall kommen Nickel, Kobalt, Eisen oder Kombinationen der erwähnten Metalle, also Nickel-Kobalt, Kobalt-Eisen, Nickel-Eisen, oder eine Legierung aus allen drei Metallen in Frage, wobei der erwähnte Gehalt an Phosphor oder Bor mit 1% bzw. 0.5% im Minimum vorhanden sein muss. Die Schicht auf dem Spinnring kann durch elektrolytische oder nichtelektrolytische Verfahren abgeschieden werden.
Aus wirtschaftlichen, ökologischen und medizinischen Gründen sind Metall-Phosphor- oder Metall-Bor-Legierungen mit überwiegendem Eisenanteil als Metall besonders interessant. Eisen ist kostengünstig, kann problemlos entsorgt und wiederverwertet werden und weist keine gesundheitlichen Ne benwirkungen auf, wie zum Beispiel das Auslösen von Allergien. Der Eisenanteil der Oberflächenschicht des Spinnrings soll bevorzugt zwischen 20 und 99 Massenprozent betragen. In den Fig. 1 und 2 ist der Härteverlauf HV über der Temperatur der Wärmebehandlung während einer Stunde für Nickel-Phosphor bzw. Nickel-Bor aufgetragen, und zwar für Verbindungen mit 2.5% Massenanteil Phosphor, bzw. 8.5% und 11% in Fig. 1, und 0.5% Bor bzw. 2.5% Bor in Fig. 2.
Die Metall-Phosphor-Beschichtung oder Metall-Bor-Beschichtung kann durch ein feinkeramisches Korn, bevorzugt Silizium-Karbid, verstärkt werden. Zur Verstärkung kommen keramische oder metallische Dispersionen in Frage.
Als Grundmaterial des Ringes werden preiswerte bzw. kostengünstig zu verarbeitende Werkstoffe wie zum Beispiel Aluminium-, Magnesium- und Zinklegierungen oder Kunststoffe verwendet, wobei die Herstellung durch Zerspanung, durch Umformung oder im Giessverfahren möglich ist.
The invention relates to a spinning ring for a ring spinning machine in which a number of spinning rings with runners are used for winding threads.
In addition to improving the shape, the development of spinning rings involves increasing the wear resistance of the surface, reducing the running-in time and making the product cheaper by choosing inexpensive base material and / or by cost-effective production. Today hardened ball bearing steel or case hardened steel is commonly used as the base material. Other alloys, such as those based on aluminum, magnesium or zinc, would be less expensive. Production from plastic is particularly inexpensive, the latter being able to be reinforced with fillers or fibers.
The wear mechanism depends, among other things. on the interplay between the spinning ring and the runner led by him. If the surface of the spinning ring is damaged, this leads to an impairment of the stability of the runner on its path and to an increased surface load at the ring-runner contact point, which leads to selective stresses on the spinning ring with increased wear. On the other hand, the runner is quickly damaged enough to have to be replaced by a new one.
Coating technology lends itself to the surface treatment of the spinning ring, with nickel-phosphorus alloys, preferably in baths, being applied to the running surface of the spinning ring.
The problem with such a nickel-phosphorus layer, for example nickel-phosphorus with 8-10% phosphorus, is that it has to be tempered at at least 300-400 ° C. in order to achieve a sufficiently high hardness (FIG. 1). This high tempering temperature is too high for numerous base materials based on aluminum, magnesium or zinc or made of plastic, as scaling, warping or melting may result.
The aim of the present invention is to improve the coating in such a way that good abrasion resistance of the layer is achieved at low tempering temperatures or without tempering, even on inexpensive base materials such as aluminum, magnesium and zinc alloys or plastics.
This object is achieved by a metal-phosphor layer, at least on the running surface of the spinning ring, which comes into contact with the rotor, with a proportion of 1-4% phosphorus or 0.5-4% boron. A tempering temperature in the range below 250 ° C. With metal-phosphorus alloys it is sufficient to obtain a high layer hardness above 750 HV. In the case of metal-boron alloys, tempering may to be completely dispensed with. Suitable metals are nickel, cobalt, iron or combinations of the metals mentioned, ie nickel-cobalt, cobalt-iron, nickel-iron, or an alloy of all three metals, the phosphorus or boron content mentioned being 1% or 0.5% minimum must be present. The layer on the spinning ring can be deposited by electrolytic or non-electrolytic processes.
For economic, ecological and medical reasons, metal-phosphorus or metal-boron alloys with a predominant iron content are particularly interesting as metal. Iron is inexpensive, can be easily disposed of and reused, and has no side effects, such as triggering allergies. The iron content of the surface layer of the spinning ring should preferably be between 20 and 99 percent by mass. 1 and 2, the hardness curve HV is plotted against the temperature of the heat treatment for one hour for nickel-phosphorus or nickel-boron, specifically for compounds with 2.5% by mass of phosphorus, or 8.5% and 11% in FIG. 1, and 0.5% boron and 2.5% boron in Fig. 2.
The metal-phosphor coating or metal-boron coating can be reinforced by a fine ceramic grain, preferably silicon carbide. Ceramic or metallic dispersions can be used for reinforcement.
Inexpensive or inexpensive materials such as aluminum, magnesium and zinc alloys or plastics are used as the base material of the ring, the production being possible by machining, shaping or casting.
