【発明の詳細な説明】 本発明は、摺動接点材料の改良に関する。[Detailed description of the invention] The present invention relates to improvements in sliding contact materials.
従来、摺動接点材料としては各種材料が用いられ、とり

9〜31重量%、Cu13〜15重景%、ZnO,5〜
1.5重量%より成る合金材料が広く用いられていた。Conventionally, various materials have been used as sliding contact materials, and in particular, as materials for brush contacts, Au9 to 11% by weight,
Pt9-11ni amount%, Pd34-36% by weight, Ag2
9-31% by weight, Cu13-15% by weight, ZnO, 5-
Alloy materials consisting of 1.5% by weight were widely used.
然し乍ら、この合金材料で製作した刷子接点では、整流
子との摺動時の凝着しやすいため耐摩耗性が劣り、摩耗
粉が生じ易く、ノイズ発生の原因となっていた。However, brush contacts made of this alloy material tend to adhere to each other when sliding with the commutator, resulting in poor wear resistance and a tendency to generate abrasion powder, causing noise.
本発明は、斯かる欠点を解消すべくなされものであり、
前記合金材料を基材としてこれに特定の元素を僅かに添

料を提供せんとするものである。The present invention has been made to eliminate such drawbacks,
The present invention aims to provide a sliding contact material with improved adhesion resistance and wear resistance by adding a small amount of a specific element to the alloy material as a base material.
本発明の摺動接点材料の1つは、Au9〜11重量%、

1) t9-11% by weight, I) d34-36% by weight, Ag
29-31% by weight, Cu13-15% by weight, ZnO

It is made by adding.

29-31% by weight, Cu13-15% by weight, Zn0.
Adding a total of 0.5 to 5 weight % of Si and Zr to an alloy material consisting of 5 to 1.5 weight % without changing the composition ratio, and further adding 0.01 to 1 weight % of Fe group metal. %.
本発明の摺動接点材料に於いて、Au9〜11重量%、
Pt9〜11重量%、Pd34〜36重量%、Ag29

いる理由は、前記合金材料の耐凝着性を向上させる為で
、0.5重量%未満では共晶反応による分散強化効果を
発揮できず、5重量%を超えると加工困難となるだけで
なく、機械的、電気的腐食により酸化物の発生量が多く

ある。In the sliding contact material of the present invention, Au9 to 11% by weight,
Pt9-11% by weight, Pd34-36% by weight, Ag29
~31% by weight, Cu13-15% by weight, Zn0.5-1
.. The reason why a total of 0.5 to 5% by weight of Si and Zr is added to the alloy material consisting of 5% by weight without changing the composition ratio is to improve the adhesion resistance of the alloy material. If it is less than 0.5% by weight, the dispersion strengthening effect due to the eutectic reaction cannot be achieved, and if it exceeds 5% by weight, it not only becomes difficult to process, but also generates a large amount of oxides due to mechanical and electrical corrosion. This results in high contact resistance and instability.

して作用する酸化物の障害となるものである。In addition to adding a total of 0.5 to 5% by weight of Si and Zr to the alloy material, the reason for adding 0.01 to 1% by weight of Fe group metal is to refine the crystal grains and further improve the durability. If the amount is less than 0.01% by weight, the effect of grain refinement will not appear, and if it exceeds 1% by weight, it will be a hindrance to the oxide that acts as a lubricant.
次に下記の左欄に示す成分組成の本発明による摺動接点
材料と従来の摺動接点材料を用いて夫々線径0.7mm
の刷子線材を作り、これを各々長さ8龍に切断し、2本
並列させて一端を幅1(1+m、長さ13mm、厚さ0
.2mmの台材に溶接し、他端に2Rの円弧状の接触部
を曲成して刷子接点を作った。Next, using the sliding contact material according to the present invention and the conventional sliding contact material having the compositions shown in the left column below, each wire diameter was 0.7 mm.
Make a brush wire rod, cut each into 8 lengths, put two of them in parallel, and one end has a width of 1 (1+m, length 13mm, thickness 0).
.. A brush contact was made by welding to a 2 mm base material and bending a 2R arc-shaped contact part at the other end.
そして夫々の刷子接点を円盤状の整流子に接触させ、整
流子を正逆回転させて下記の試験条件にて摺動試験を行

に不ずような結果を得た。Then, each brush contact was brought into contact with a disk-shaped commutator, the commutator was rotated forward and backward, and a sliding test was conducted under the following test conditions, and the wear amount and contact resistance were measured. I got similar results in the column.

Min contact pressure: 100g (blank below) As is clear from the table above, the brush contacts of Examples 1 to 4 have significantly less wear than the conventional brush contacts, and the contact resistance is equally low and stable. I understand that. This is simply because the sliding contact material of the present invention, which constitutes the brush wire of the brush contacts of Examples 1 to 4, has improved adhesion resistance during sliding due to dispersion reinforcement of Si and Zr. . In particular, the reason why the amount of wear of the brush contacts of Example 3.4 is even smaller than that of the brush contacts of Examples 1 and 2 is that Fe group metal is added to the sliding contact material of the present invention constituting the brush wire. This is because the crystal grains have become finer and more dispersed, further improving wear resistance.
以上詳記した通り本発明による摺動接点材料によれば、
従来の摺動接点材料に比べ着しく耐摩耗性に優れ、摩耗
粉の発生量が極めて少なく、ノイズの発生が殆んど無く
、また従来の摺動接点材料による場合と同等の接触抵抗

。As detailed above, according to the sliding contact material according to the present invention,
Compared to conventional sliding contact materials, it is more comfortable and has excellent wear resistance, generates extremely little abrasion powder, generates almost no noise, and has contact resistance equivalent to that of conventional sliding contact materials. This has the effect of providing a brush contact point.
