The present invention aims to provide a sliding contact material with improved properties.

Cu 15.5〜17.5重量%より成る合金材料に、
その組成比に変更を加えずに、B、Si、Ge、TIの
少なくとも一種を0.5〜10M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潤滑剤となる
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潤滑剤としての効果を発揮でき
ず、10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。An alloy material consisting of 15.5 to 17.5% by weight of Cu,
The reason why at least one of B, Si, Ge, and TI is added in an amount of 0.5 to 10 M% without changing the composition ratio is that it acts as a lubricant to improve the wear resistance of the alloy material. This is to generate an appropriate amount of oxides; if it is less than 0.5% by weight, the amount of oxides generated is too small to be effective as a lubricant, and if it exceeds 10% by weight, the amount of oxides generated increases.
The contact resistance becomes high and, moreover, it becomes unstable.

If it is less than 0.01% by weight, the effect of crystal grain refinement will not appear;
.. If the amount exceeds 5% by weight, the oxide acting as a lubricant (3) becomes a hindrance.
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0.7 t
mの刷子線材を作り、これを各々長さ8鶴に切断し、2

測定した処、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 compositions shown in the left column below, each wire diameter was 0.7 t.
Make a brush wire of m length, cut it into 8 cranes each, and make 2
These are lined up and one end has a width of 10fi, a length of 131mm, and a thickness of 0.
A brush contact was made by welding to a 2U+ base material and bending a 2R arc-shaped contact portion 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.

100g Test time: 7 hours (4) (5) As is clear from the table above, the brush contacts of Examples 1 to 7 had significantly less wear than the conventional brush contacts, and the contact resistance was low and stable. I know that there is.

発明の摺動接点材料にFe族金属が添加されて、その結
晶粒が微細化して分散していて、耐摩耗性が一段と向上
しているからに他ならない。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 7,
This is because oxides such as i, Ge, and TI are generated, and these oxides act as lubricants and improve wear resistance. Moreover, since the oxide is soft, it is easily removed by the sliding action, so the contact resistance remains unchanged. Especially Example 5
The reason why the amount of wear of the brush contacts of Examples 1 to 7 is even smaller than that of the brush contacts of Examples 1 to 4 is that Fe group metal is added to the sliding contact material of the present invention constituting the brush wire, and the crystals of the Fe group metal are This is because the grains are finer and more dispersed, further improving wear resistance.

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,
It has significantly better wear resistance than 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. (6) There is an effect that a brush contact point can be obtained.
