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添加さ

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, uses the generated oxide as a lubricant, and improves wear resistance. The present invention aims to provide a sliding contact material.
本発明の摺動接点材料の1つは、P d 87〜93重
量%、Ru7〜13重量%より成る合金材料にその組成

ある。The reason why at least one type of Cd is added in an amount of 0.5 to 15% by weight is to generate an appropriate amount of oxide that becomes a lubricant in order to improve the wear resistance of the alloy material, and if it is less than 0.5% by weight, If the amount of oxide generated is small, it cannot exhibit its effect as a lubricant, and if it exceeds 15% by weight, the amount of oxide generated increases, contact resistance becomes high, and it becomes unstable.

の障害となるものである。Furthermore, in addition to adding 0.5 to 15% by weight of at least one of Nb, In, Ba, and Cd to the alloy material, Fe
The reason for adding 0.01 to 0.5% by weight of group metals 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,
If it exceeds 0.5% by weight, it will interfere with the oxide acting as a lubricant.

うな結果を得た。Next, brush wires with a wire diameter of 0.1 m were made 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, and each wire was cut into 8 lengths. , two in parallel and one end with width IQw+, length 13fi, thickness 0.2
A brush contact was made by welding it to a crane base material and bending a 2R (3) arc-shaped contact part on 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.

0g Test time: 7 hours (blank below) (4) (S) As is clear from the table above, the brush contacts of Examples 1 to 5 had significantly less wear and contact resistance than the conventional brush contacts. It can be seen that it is low and stable.

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 5, is
This is because oxides of n, Ba, Cd, etc. are generated, and these oxides act as lubricants, improving wear resistance. Moreover, since the oxide is soft, it is easily removed by the sliding action, so the contact resistance remains unchanged. In particular, the reason why the amount of wear of the brush contact of Example 5 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 that constitutes the brush wire. This is because the crystal grains are fine and dispersed, further improving wear resistance.

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. .
