本発明は高速精紡に於いて優れた機能を発揮す
る紡機用リングの構成に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the construction of a ring for a spinning machine that exhibits excellent functionality in high-speed spinning.
従来の紡機用リングは、一般に低炭素鋼が用い

出来ないという欠点があつた。
Conventional rings for spinning machines are generally made of low carbon steel, and are subjected to carburizing and quenching as a surface hardening process. However, with the above ring, the spindle rotation speed is over 20000rpm (current high speed rotation is
17,000r.pm to 18,000r.pm), the drawback was that the traveler would seize early and fly apart due to the increased frictional resistance between the ring and the traveler and the rapid rise in frictional heat, making continuous operation impossible.
この為、フランジの表面に硬質微粒子を共析物

しないといつた欠点があつた。 For this reason, composite plating using hard fine particles as a eutectoid material has been considered on the surface of the flange, but as the plating film thickness of the composite plating becomes thicker, the surface roughness of the plating surface becomes rougher, making it less effective. There was a drawback that I was unable to fully demonstrate my potential.

The present invention involves cutting carbon steel as a raw material to form a ring with a desired shape, then heat-treating the ring, and subjecting the ring to surface polishing, and then hard fine particles with a particle size of 0.2μ to 3μ are added to the surface of the ring as a eutectoid material. A composite plating layer with a nickel alloy containing nickel and phosphorous as a matrix is formed with a content in the range of 2 to 15% (wt%) to a thickness of 5μ to 30μ, and then At a temperature of 350℃ to 480℃ to 40~
The heat treatment takes 100 minutes to crystallize the nickel alloy that is the matrix of the composite plating layer, increasing the hardness of the coating to a high hardness of Hv800 to Hv1100, and at the same time improving the adhesion between the hard particles and the nickel alloy matrix. will be strengthened. Furthermore, by polishing the surface on which the traveler contacts and slides, it forms a mixture of three parts: nickel plating of the matrix, parts where hard particles protrude, and parts with micro holes where hard particles have fallen off. In addition, by setting the surface roughness to Ra0.2μ or less, the composite plating layer's good wear resistance, seizure resistance, and sliding properties can be fully demonstrated, making it possible to maintain the traveler's performance even under high-speed spindle rotation conditions. It becomes possible to sufficiently suppress the frictional resistance between the
上記マトリツクスとして用いるニツケル合金
は、ニツケル−リン合金、ニツケル−タングステ
ン−リン合金などがある。 Nickel alloys used as the matrix include nickel-phosphorus alloys and nickel-tungsten-phosphorus alloys.
上記硬質微粒子としては、炭化ケイ素、炭化タ
ングステン、炭化ホウ素、窒化ホウ素、酸化アル
ミニウムなどがある。 Examples of the hard particles include silicon carbide, tungsten carbide, boron carbide, boron nitride, and aluminum oxide.
硬質微粒子の大きさが3μを超えるとメツキ層
からの脱落が早くなり、0.2μ未満では耐摩性が劣
る。 If the size of the hard fine particles exceeds 3μ, they will fall off quickly from the plating layer, and if the size is less than 0.2μ, the wear resistance will be poor.
複合メツキ中の硬質微粒子の含有率を２〜15％
（重量％）としたが、２％未満では十分な耐摩性
が得られず、15％を超えると複合メツキ層の表面
における硬質微粒子の占める割合が大きくなり摺
動生に劣る。 The content of hard fine particles in the composite plating is 2 to 15%.
(% by weight), but if it is less than 2%, sufficient wear resistance cannot be obtained, and if it exceeds 15%, the proportion of hard fine particles on the surface of the composite plating layer becomes large, resulting in poor sliding performance.
複合メツキ層の厚さを５〜30μとしたが、5μ未
満では高速における耐摩耗性において不充分であ
り、30μを超えると処理時間が極めて長くなり、
コストアツプになるという欠点がある。 The thickness of the composite plating layer was set to 5 to 30 μm, but if it is less than 5 μm, the wear resistance at high speeds is insufficient, and if it exceeds 30 μm, the processing time will be extremely long.
The disadvantage is that it increases costs.
さらに、トラベラの接触、摺動する表面の表面

う欠点がある。 Furthermore, the surface roughness of the contact and sliding surface of the traveler was reduced to Ra0.2μ or less by polishing.
The surface roughness of composite plating without polishing is Ra
It has a surface of less than 0.2μ and has poor smoothness, which disturbs the running of the traveler and has the drawback of poor high-speed performance.

減させたものである。 By reducing the surface roughness to Ra0.2μ or less through polishing, it not only makes the traveler run smoother, but also
On the outermost surface of the composite plating, hard fine particles with high hardness and excellent wear resistance are exposed in the nickel alloy that has high hardness and good wear resistance, seizure resistance, and sliding properties, and the hard fine particles are further removed. By creating a mixed state of the three with minute parts, the frictional resistance with the traveler is reduced even in the high speed range of spindle rotation.

共析物質とする複合メツキ層４を形成する。 Particle size as hard fine particles on the surface of the ring 1 above.
Using 1μ of silicon carbide 2 as a eutectoid, electroless nickel was added so that its content was approximately 4% by weight.
Phosphorus composite plating is performed to form a composite plating layer 4 on the ring surface, using a nickel-phosphorus alloy 3 as a matrix and silicon carbide as a eutectoid.

が強化される。 Next, the material is heated in a heat treatment furnace at about 400°C for about 1 hour, and the nickel-phosphorus alloy of the matrix obtains a high hardness of about Hv1000 on the Vickers hardness as shown in Fig. 3 due to the crystallization of the nickel-phosphorus. At the same time, the adhesion between the eutectoid silicon carbide and the nickel-phosphorus alloy matrix is strengthened.

形成して本発明の紡機用リングを構成する。 Furthermore, the contact of the traveler, the sliding flange surface 5
Polishing processing such as wrapping is applied to the surface of the traveler, and the surface in contact with the traveler is formed in a mixed state of nickel plating of the matrix, areas where hard fine particles protrude, and minute holes where hard fine particles have fallen off, and the surface is rough. The ring for a spinning machine of the present invention is formed by forming a smooth surface with a Ra of 0.2μ or less.

ラ寿命を延長させる利点がある。 In addition, the best hard particles to be eutectoid in the composite plating layer are silicon carbide, which has high hardness, high chemical resistance, high wear resistance, and good thermal conductivity, and can dissipate the frictional heat generated when the traveler runs. This has the advantage of easily extending the life of the traveler.
