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は、整流
子との摺動時に凝着して耐摩耗性が劣り、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添加さ
せて、摺動時に発生する酸化物に（１）
より凝着を防止し、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 uses the above-mentioned alloy material as a base material and adds a specific material to it to prevent adhesion of oxides generated during sliding (1). The present invention aims to provide a sliding contact material with improved wear resistance.
本発明の摺動接点材料は、Ｐ ｄ ８７〜９３重量％１

更を加えずに、Ａ Ｉ ＋ Ｇ ａ １Ｍ ｎ ＋
Ｎ ｉ ＋ Ｇ ｅ 。The sliding contact material of the present invention has a P d of 87 to 93% by weight 1
A I + Ga 1M n + without changing the composition ratio of an alloy material consisting of 7 to 13% by weight of Ru
N i + G e.
Ｓｔの少なくとも一種を０．５〜１５重量％添加して成
るものである。At least one type of St is added in an amount of 0.5 to 15% by weight.
本発明の摺動接点材料に於いて、Ｐ ｄ ８７〜９３重

組成比に変更を加えずに、ＡＩ、Ｇａ、Ｍｎ。In the sliding contact material of the present invention, AI, Ga, and Mn are added to the alloy material consisting of 87 to 93% by weight of P d + 7 to 13% by weight of Ru without changing the composition ratio.
Ｎ ＋ ＋ Ｇ ｅ ＋ Ｓ ｉの少なくとも一種
を０．５〜１５重量％添加している理由は、前記合金材
料の耐摩耗性を向上すべく凝着を防止する酸化物を適量
発生させる為で、０．５重量％未満では酸化物の発生量
が少なくて凝着を防止する効果を発揮できず、１５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。The reason why 0.5 to 15% by weight of at least one of N + + Ge + Si is added is to generate an appropriate amount of oxide that prevents adhesion in order to improve the wear resistance of the alloy material. If the amount is less than 0.5% by weight, the amount of oxides generated is small and the effect of preventing adhesion cannot be exhibited, and if it exceeds 15% by weight, the amount of oxides generated is large, resulting in high contact resistance. This is unstable.

な結果を得た。Next, (2) brush wires with a wire diameter of 0.7 tm were made using the sliding contact material according to the present invention and the conventional sliding contact material having the component compositions shown in the left column below, and each of these brush wires had a length of 8 tm.
Cut into 1 piece, put 2 pieces in parallel and make one end width] 0+n, length 1
A brush contact was made by welding to a composite material of 3N and 0.2fi thickness, and a 2R arc-shaped contact portion was bent 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.

ない。This is simply due to the fact that the sliding contact material of the present invention, which constitutes the brush wire of the brush contacts of Examples 1 to 6, has an AI and a G when sliding.
Oxides such as a, Mn, Ni, Ge, and St are generated, and these oxides prevent adhesion and improve wear resistance, and the amount of generated oxides is balanced with the amount of wear. Nothing but.

粉の発生量が極めて少なく、また接触抵抗が低く安定し
ノイズの発生が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. .
