Abstract
Description
【発明の詳細な説明】 本発明番戴すり接点材料の改良に関する。[Detailed description of the invention] The present invention relates to improvements in contact materials.
従来より小型モータの整流子外周の接点片を作るすり接
点材料としては主としてＣｕが用いられてきたが、Ｃｕ
は軟化温度が低い為、整流子の回転すり接触中凝着現象
が生じ易く、接触抵抗が高く且つ不安定でノイズが発生
するという欠点があった。Traditionally, Cu has been mainly used as a sliding contact material for making contact pieces around the commutator of small motors, but Cu
Since the softening temperature is low, adhesion tends to occur during rolling contact of the commutator, and the contact resistance is high and unstable, resulting in noise generation.
本発明はかかる欠点を解消すべくなされたもので、軟化
温度を高（して接触抵抗を低く安定させたすり接点材料
を提供せんとするものである。The present invention has been made in order to eliminate such drawbacks, and aims to provide a sliding contact material that has a high softening temperature and has a low and stable contact resistance.
本発明のすり接点材料は、Ｃｕ中に、Ａｕ。The sliding contact material of the present invention contains Au in Cu.
Ａｇ、Ｐｄ、Ｐｔ、Ｒｕ、Ｒｈの少くとも一種を（１）
合計で０．５〜１０ｗ７ｉ量％添加して成るものである
。At least one of Ag, Pd, Pt, Ru, and Rh (1) is added in a total amount of 0.5 to 10% by weight.

凝着防止効果が変らないものである。In the sliding contact material of the present invention, Au is contained in Cu.
, Ag, Pd, Pt, Ru, and Rh at a total of 0.5 to 10% in total are added to increase the softening temperature of Cu to form a contact piece on the outer periphery of a commutator of a small motor during rotation. This is to prevent Cu from adhering and to make the contact resistance low and stable with little variation.
The effect of increasing the softening temperature is small, and the adhesion phenomenon of the contact piece cannot be prevented, and if it exceeds 10% by weight, the cost will increase and the anti-adhesion effect will not change.
次に本発明によるすり接点材料と従来のすり接点材料に
て作った小型モータの整流子外周の接点片について説明
する。Next, a contact piece for the outer periphery of a commutator of a small motor made of a sliding contact material according to the present invention and a conventional sliding contact material will be explained.

後記の表の右欄に示すような結果を得た。A contact piece with a thickness of 0.2 mm was made using the sliding contact material according to the embodiment of the present invention and the conventional sliding contact material having the composition shown on the left side of the table below, and this contact piece was made as shown in the drawing. 3 on the outer circumference
On the top and bottom of the outer circumferential surface of a commutator L with a diameter of 10 mm and a length of 6 mm, there are 1.0 mm in diameter made of Ag-Cu alloy and 0.0 mm in thickness.
On the 2nd, a brush with a length of 10 cranes (2) A brush contact 3 having one child plate 2 was brought into sliding contact so as to face each other, and a rotation test was performed on the commutator 1 under the test conditions described later. When the consumption amount and contact resistance of 1a were measured,
The results shown in the right column of the table below were obtained.

It can be seen that the contact piece of the example has a contact resistance of 1 to 2 Ω, whereas the contact piece of the example has a contact resistance of 0.2 to 0.3 Ω, which is extremely low and stable with little variation.

ものである。As detailed above, the sliding contact material of the present invention has a high softening temperature, so the contact pieces around the commutator of a small motor made using this material do not stick together during sliding contact, and the contact resistance is low and stable. It does not generate noise (and has excellent wear resistance).
