Abstract

PURPOSE:To obtain a material for a brush contact having superior wear resistance and generating little noise by adding restricted amounts of In and other specified element such as Te to an Au-Pt-Pd-Ag-Cu-Zn material for a brush contact as a base material. CONSTITUTION:An alloy material consisting of, by weight, 9-11% Au, 9-11% Pt, 34-36% Pd, 29-31% Ag, 13-15% Cu and 0.5-1.5% Zn is used as a base material. A material for a brush contact is obtd. by adding 1-10wt% In and 0.5-3wt% one or more among Te, Ti, Li and Mg to the base material without changing the ratio in the composition. To the base material may be further added 0.01-0.5wt% Fe group metal.

量％を超えると酸化物の発生量が多くなり、接触抵抗か
高くなり、その上不安定となるものである。The reason why 0.5 to 3% by weight of at least one type of Mg is added is that In and T are added to improve the wear resistance of the alloy material.
This is to disperse and harden intermetallic compounds with e, Ti, Li, and Mg, and 1% by weight of In or Te, Ti, Li,
If at least one type of Mg is less than 0.5% by weight, the effect cannot be sufficiently obtained, and if In is 10% by weight or "I"e,
If at least one of I, Li, and Mg exceeds 3% by weight, the amount of oxides generated increases, the contact resistance becomes high, and the contact resistance becomes unstable.

In addition to adding 0.5 to 3% by weight of at least one of Ti, Li, and Mg, 0.01 to 0.5% of p6 group metal was added.
The reason for adding 0.3% by weight is to refine the crystal grains and further improve wear resistance.If it is less than 0.01% by weight, the effects of crystal grain refinement will not appear. This is because even if you exceed it, you will not get any better effect.

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飼料を用いて夫々線径０．７ｍＩ
Ｎの刷子線材を作り、これを各々長さ８能に切断し、２

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 having the composition shown in the left column below and the conventional sliding contact feed, each wire diameter was 0.7 mI.
Make N brush wire rods, cut each into 8 lengths, and
These are lined up and one end has a width of 10 pieces and a length of 1311++n.
A brush contact was made by welding to a composite material with a thickness of 0.2 mm and bending a 2R arc-shaped contact portion at the other end.

そして夫々の刷子接点を円盤状の整流子うこ接触させ、
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
行い、摩耗量及び接触抵抗を測定した処、下記の表の右
欄に示すような結果をｆｆ４た。Then, each brush contact point is brought into contact with the disk-shaped commutator scale,
A sliding test was conducted under the following test conditions by rotating the commutator in forward and reverse directions, and the wear amount and contact resistance were measured, and the results were as shown in the right column of the table below.

=130-120 m/min contact crab 10
0g Test time: 7 hours (J22 bottom margin) As is clear from the table above, the brush contacts of Examples 1 to 7 have significantly less wear compared to the conventional brush contacts, and the contact resistance is low and stable. I understand that.

耗性か一段と向上しているからに他ならない。This is simply the sliding contact material of the present invention constituting the brush wire of the brush contacts of Examples 1 to 7, or In, Te, and Ti.
This is because the dispersion of intermetallic compounds with , Li, and Mg hardens and improves wear resistance. Especially Example 2.
6.7 brush contacts or Example 1. 3. 4. The reason why the amount of wear is even smaller than that of the brush contact in No. 5 is that Fe group metal is added to the sliding contact material of the present invention that makes up the brush wire, and the crystal grains thereof are refined and dispersed. This is because the wear resistance has further improved.

以上詳記した通り本発明による摺動接点飼料によれは、
従来の摺動接点材料に比へ著しく耐摩耗性に優れ、摩耗
粉の発生量か極めて少なく、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よりも低く安定し

効果かある。As detailed above, the sliding contact feed according to the present invention has the following features:
It has significantly superior wear resistance compared to conventional sliding contact materials, generates extremely little wear powder, generates almost no noise, and has a lower and more stable contact resistance than conventional sliding contact materials. This has the advantage that it is possible to obtain a brush contact having the following characteristics.
