Description
【発明の詳細な説明】 本発明は、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 sliding contact materials.
従来より／１１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、Ｃ
ｕ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。Conventionally, Cu has been mainly used as the sliding contact material for making contact pieces around the commutator of /11 motors, but Cu
Since u has a low softening temperature, it tends to cause adhesion during rotating contact with the commutator, and has the drawbacks of high contact resistance, instability, and 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
温度を高く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 a low and stable contact resistance.
本発明のすり接点材料は、Ｃｕ中に、Ｃｒ、 ｐ。The sliding contact material of the present invention contains Cr and p in Cu.

るものである。In the sliding contact material of the present invention, Cr is contained in Cu.
, P, Zr, Mg in total of 0.5 to 15
The purpose of adding % by weight is to increase the softening temperature of Cu by forming a peritectic alloy or precipitation, thereby preventing the contact pieces on the outer periphery from adhering during the rotation of the commutator of a small motor, and making contact. This is to make the resistance low and stable with little variation. If it is less than 0.5% by weight, the effect of increasing the softening temperature of Cu is small and the adhesion phenomenon of the contact piece cannot be prevented, and if it exceeds 15% by weight, The amount of oxide produced increases, and the contact resistance of the contact piece becomes high and varies widely, making it unstable.
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.

表の右１１ｓこ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 in the left column of the table below, and this contact piece was made as shown in the drawing. 3 on the outer circumference
The commutator has a diameter of 10fl and a length of 6 (2).The upper and lower sides of the outer surface of the commutator 1 are made of an Ag-Cu alloy. A rotation test was carried out on the commutator l under the test conditions described below, with the stinging contacts 3 having one brush plate material 2 having a thickness of 0.2 cm and a length of lO cm being brought into sliding contact so as to face each other. When the wear amount and contact resistance of the contact piece 1a were measured, the results shown in the table 11s on the right below were obtained.

Further, it can be seen that the contact resistance of the contact piece of the conventional example is 1 to 2 Ω, whereas the contact resistance of the contact piece of the embodiment is 0.2 to 0.4 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.
