Abstract
Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、摺動接点材料の改良に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to improvements in sliding contact materials.
（従来の技術）
従来より自動車用燃料ポンプ等の小型モータの摺動接点
材料の一つとして、潤滑性に優れたＣｕ−Ａｇ合金が用
いられてきたが、Ｃｕ−Ａｇ合金の摺動接点材料は消耗
し易いという欠点があり、従ってこの摺動接点材料で小
型モータの整流子の外周の接点片を製作して使用した場
合には寿命が短かかったり、整流子の回転速度が大きく
ばらついて不安定なものとなっていた。(Prior art) Cu-Ag alloy with excellent lubricity has been used as one of the sliding contact materials of small motors such as automobile fuel pumps, but the sliding contact material of Cu-Ag alloy has the disadvantage that it is easily worn out, so if this sliding contact material is used to manufacture and use contact pieces around the commutator of a small motor, the service life will be short and the rotation speed of the commutator will vary widely. It had become unstable.
（発明の目的）
本発明は、かかる欠点を解消すべくなされたものであり
、Ｃｕ−Ａｇ合金の潤滑性を維持しつつ耐消耗性を向上
させた摺動接点材料を提供せんとするものである。(Object of the Invention) The present invention was made in order to eliminate such drawbacks, and aims to provide a sliding contact material that maintains the lubricity of the Cu-Ag alloy and has improved wear resistance. be.
（課題を解決するための手段）
本発明の摺動接点材料は、Ｃｕ中に、Ａｇ０．１〜１５
ｗｔ％とＳｎＯ，１〜１０ｗｔ％添加して成るものであ
る。(Means for Solving the Problems) The sliding contact material of the present invention contains 0.1 to 15 Ag in Cu.
It is made by adding 1 to 10 wt% of SnO and 1 to 10 wt% of SnO.
かかる本発明の摺動接点材料に於いて、Ｃｕ中に０．１
〜１５ｗｔ％のＡｇを添加した以外にＳｎを０．１〜１
０ｗｔ％添加するのは、Ｓｎを添加すると硬さが高くな

し、表面に若干の酸素膜が生成するので接触抵抗は、若
干高目になるが、整流子の回転速度には、悪影響を及ぼ
さない。In the sliding contact material of the present invention, 0.1
In addition to adding ~15 wt% of Ag, Sn was added from 0.1 to 1
The reason why 0wt% is added is that adding Sn increases the hardness and that a slight oxide film is formed on the surface of Cu-A.
In addition to g-alloys, lubricity is improved and wear is suppressed. However, since a slight oxygen film is formed on the surface, the contact resistance becomes a little high, but it does not adversely affect the rotation speed of the commutator.
Ｓｎ０．１％以下では、硬さの上昇および、表面に生じ
る酸化膜が、僅かであり、消耗に及ぼす効果が得られず
、５ｎｌＯ％を超えると、硬さの上昇は十分であるが、
表面酸化膜が厚くなり、接触抵抗が急激に増大するため
に、整流子の回転速度−に悪影響を及ぼすようになる。If Sn is 0.1% or less, the increase in hardness and the formation of an oxide film on the surface are slight, and no effect on wear can be obtained; if it exceeds 5nlO%, the increase in hardness is sufficient, but
The surface oxide film becomes thicker and the contact resistance increases rapidly, which adversely affects the rotational speed of the commutator.

。Using the sliding contact material according to the embodiment of the present invention and the conventional sliding contact material having the composition shown in the right column of the table below, a commutator 1 of a small motor with a diameter of 6 fflf 111 and a length of 9 as shown in the drawings is used. A contact piece 1a with a thickness of 0.2 mm is formed on the outer periphery of the
Brush contacts 2 made of C-Cu with a diameter of 5 mm and a length of 10 mm are brought into sliding contact with the upper and lower surfaces of the outer peripheral surface of the contact piece 1a so as to face each other, and the commutator 1 is rotated under the test conditions described later. A test was conducted, and the amount of wear of the contact piece 1a and the variation in the rotational speed of the commutator 1 were measured, and the results shown in the right column of the table below were obtained.

: Rotation speed of DC5A commutator'
Rotation time of 3000 rpm commutator = 500 hours Contact force of brush contact: 10 g As is clear from the table above, the amount of wear of the contact piece of the conventional example is 3
~6μ, whereas the amount of wear of the contact piece in the example was 2μ.
It can be seen that the wear resistance is excellent as it decreases to ~3.5μ. Furthermore, while the variation in the rotational speed of the commutator with the contact piece of the conventional example was 8 to 11%, the variation in the rotational speed of the commutator with the contact piece of the example was significantly reduced to 3 to 5%. It can be seen that This is simply because the contact piece of the example is made of a Cu-Ag-Sn alloy and has high hardness, and a small amount of tin oxide is generated on the surface, resulting in a low amount of wear.
