Description
【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
わけ刷子接点用の材料としては、Ｐ ｄ ８７〜９３重
量％、Ｒｕ７〜１３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, alloy materials consisting of 87 to 93% by weight of P d and 7 to 13% by weight of Ru have been widely used as materials for brush contacts.
然し乍ら、この合金材料で製作した刷子接点で（１）
は、整流子との摺動時の耐摩耗性が劣り、摩耗粉が生じ
易くノイズ発生の原因となっていた。However, the brush contacts (1) made of this alloy material had poor abrasion resistance when sliding with the commutator, and were prone to generate abrasion powder, causing noise.
本発明は、斯かる欠点を解消すべくなされたものであり
、前記合金材料を基材としてこれに特定の材料を僅かに
添加させて、耐摩耗性を向上させた摺動接点材料を提供
せんとするものである。The present invention has been made to eliminate such drawbacks, and provides a sliding contact material with improved wear resistance by using the above-mentioned alloy material as a base material and adding a small amount of a specific material thereto. That is.

3% by weight of Sn and 7-13% by weight of Ru without changing the composition ratio.
It is made by adding 0.5 to 3% by weight of at least one of e, Sr, and Zr, and further adding 0.01 to 0.5% by weight of Fe group metal.

その効果を十分発揮できず、Ｓｎが１０重量％を超える
かＴｅ、Ｓｒ。In the sliding contact material of the present invention, 1 to 10% by weight of Sn is added to the alloy material consisting of 87 to 93% by weight of P d and 7 to 13% by weight of Ru without changing the composition ratio (2). The reason for adding 0.5 to 3% by weight of at least one of Te, Sr, and Zr is that in order to improve the wear resistance of the alloy material, the dispersion of the intermetallic compounds of Sn, Te, Sr, and Zr makes it hard. This is because Sn is less than 1% by weight or Te
If at least one of , Sr, and Zr is less than 0.5% by weight, the effect cannot be fully exhibited, and if Sn exceeds 10% by weight, Te or Sr.
Ｚｒの少なくとも一種が３重量％を超えると酸化物の発
生量が多くなり、接触抵抗が高くなり、その上不安定と
なるものである。If at least one type of Zr exceeds 3% by weight, the amount of oxides generated will increase, contact resistance will increase, and furthermore, it will become unstable.

微細化の効果が現われず、０．５重量％を超えてもそれ
以上の効果が得られないものである。In addition, 1 to 10% by weight of Sn and TeSr are added to the alloy material.
, Zr in an amount of 0.5 to 3% by weight, and 0.5% to 3% by weight of at least one of Zr and 0.5% to 3% by weight of at least one of Zr. RitL+ added at 0.5% by weight is intended to refine the crystal grains and further improve the wear resistance, and if it is less than 0.01% by weight, the effect of grain refinement will not appear, and 0. Even if it exceeds .5% by weight, no further effect can be obtained.

ような結果を得た。Next, brush wire rods each having a wire diameter of 0.7 mm were made 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. Cut into dragon shapes, place two pieces in parallel, and one end is 10 mm wide and 1 long.
It was welded to a base material of 31F+ and 0.2mm thick, and a brush contact was made by bending the arc-shaped contact part of 2) at the other end. Then, each brush contact was brought into contact with a disk-shaped commutator, and the commutator was rotated in forward and reverse directions to perform a sliding test under the following test conditions, and the wear amount and contact resistance were measured. The results shown in the column were obtained.

上記の表で明らかなように実施例１〜４の刷子接点は従
来例の刷子接点に比し摩耗量が著しく少なく、接触抵抗

= 130 to 120 rn/min Contact crab 100g Test time: 7 hours (blank below) (4) (5) As is clear from the table above, the brush contacts of Examples 1 to 4 are superior to the conventional brush contacts. It can be seen that the amount of wear is extremely small and the contact resistance is low and stable.
これはひとえに実施例１〜４の刷子接点の刷子線材を構

に他ならない。This is because the sliding contact material of the present invention constituting the brush wire of the brush contacts of Examples 1 to 4 is Sn, Te, and Sr.
This is because it becomes hard due to the dispersion of Zr intermetallic compounds and has good wear resistance. In particular, the reason why the amount of wear of the brush contact of Example 4 is even smaller than that of the brush contacts of Examples 1 to 3 is that Fe group metal is added to the sliding contact material of the present invention that constitutes the brush wire. This is because the crystal grains have become finer and more dispersed, further improving wear resistance.

従来の摺動接点材料に比べ著しく耐摩耗性に優れ、摩耗
粉の発生量が極めて少なく、また接触抵抗が低く安定し
ノイズの発生の殆んど無い刷子接点を得ることができる
という効果がある。As detailed above, according to the sliding contact material according to the present invention,
Compared to conventional sliding contact materials, it has significantly superior wear resistance, generates extremely little abrasion powder, and has the effect of providing a brush contact with low and stable contact resistance and almost no noise. .
