Abstract

PURPOSE:To improve the wear resistance of the resulting sliding contact material by adding small amounts of In and >=1 kind among Te, Ti, Li and Mg to an alloy material having a specified composition consisting of Pd, Ag and Cu. CONSTITUTION:This sliding contact material is obtd. by adding, by weight, 1- 10% In and 0.5-3% >=1 kind among Te, Ti, Li and Mg to an alloy material consisting of 30-50% Pd, 20-40% Ag and 20-40% Cu without changing the ratio in the composition. To the alloy material may be further added 0.01-0.5% Fe group metal. This sliding contact material can give a brush contact which causes a smaller extent of wear than a brush contact made of a conventional sliding contact material, has low and stable contact resistance, and hardly generates noise.

The present invention aims to provide a sliding contact material with improved wear resistance by adding a small amount of a specific material to the alloy material as a base material.

合金材料に、その組成比に変更を加えずに、Ｉｎを１〜
１０重量％とＴｅ、Ｔｉ、Ｌｉ、Ｍｇの少なくとも一種
を０．５〜３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ＩｎとＴｅ。In the sliding contact material of the present invention, Pd is 30 to 50% by weight.
, Ag2O ~ 40% by weight, Cu2O ~ 40% by weight, without changing the composition ratio, In is added 1 ~ 40% by weight.
The reason for adding 10% by weight of In and Te and 0.5 to 3% by weight of at least one of Te, Ti, Li, and Mg is to improve the wear resistance of the alloy material.

Ｔｉ、Ｌｉ、Ｍｇの金属間化合物を分散させて硬くする
為で、Ｉｎが１重量％あるいばＴｅ、Ｔｉ。This is to disperse intermetallic compounds of Ti, Li, and Mg to make them hard, and if In is present at 1% by weight, Te or Ti is used.

Ｌｉ、Ｍｇの少なくとも一種が０．５重量％未満ではそ
の効果を十分発揮できず、Ｉｎが１０重量％あるいはＴ
ｅ、Ｔｉ、Ｌｉ、Ｍｇ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 of Li and Mg is less than 0.5% by weight, the effect cannot be fully exhibited, and if In is 10% by weight or T
If at least one of Ti, Li, and Mg exceeds 3% by weight, the amount of oxides generated will increase, contact resistance will increase, and furthermore, it will become unstable.

また、前記合金材料にＩｎを１〜１０重量％とＴｅ５Ｔ
ｉ、Ｌｉ、Ｍｇの少なくとも一種を０．５〜３重量％添
加した他に、更にＦｅ族金属を０，０１〜０．５重量％
添加した理由は、結晶粒を微細化し、更に一段と耐摩耗
性を向上させる為で０．０１重量％未満では結晶粒微細
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からである。In addition, 1 to 10% by weight of In and Te5T are added to the alloy material.
In addition to adding 0.5 to 3% by weight of at least one of i, Li, and Mg, 0.01 to 0.5% by weight of Fe group metal is added.
The reason for adding it is to refine the crystal grains and further improve wear resistance.If it is less than 0.01% by weight, the effect of grain refinement will not appear, and if it exceeds 0.5% by weight, it will not be effective. This is because no effect can be obtained.

処、下記の表の右欄に示すような結果を得た。Next, using the sliding contact material according to the present invention and the conventional sliding contact material having the composition shown in the left column below, brush wire rods each having a wire diameter of 0.7 tsuru were made, and each brush wire was cut into 8 tsuru lengths. Then, two of them were placed in parallel and one end was welded to a base material of width 10-2 length 13u and thickness 0.2 Tsuru, and a 2R arc-shaped contact part was bent at the other end to make a brush contact. . 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.

Speed: 130-120 m/min Contact crab 100 g Test time = 7 hours As is clear from the table above, the brush contacts of Examples 1-6 had significantly less wear and contact resistance than the conventional brush contacts. It can be seen that it is low and stable.

に他ならない。This is simply due to the fact that the sliding contact material of the present invention constituting the brush wire of the brush contacts of Examples 1 to 6 contains In, Te, and Ti.
, Li, Mg become hard due to dispersion of intermetallic compounds,
This is because the wear resistance is improved. Especially Example 5
．． The reason why the amount of wear of the brush contact of No. 6 is even smaller than that of the brush contacts of Examples 1 to 4 is that the Fe group metal is added to the sliding contact material of the present invention constituting the brush wire and the crystal grains are fine. This is due to the fact that it has been further improved in 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. .
