Abstract
Description
【発明の詳細な説明】 本発明は、摺動＃点材料の改良に関する。[Detailed description of the invention] The present invention relates to improvements in sliding point materials.
従来よ〕小型モータの整流子外周の接点片を作る摺動接
点材料としては主としてＩｆｉＡｇが用いられてきたが
、ＡｇＦｉ軟化温度が低い為、整流子の回転摺動中凝着
現象が生じ易く、接触抵抗が高く且つ不安定であるとい
う欠点があった。Conventionally, IfiAg has been mainly used as a sliding contact material to make the contact pieces around the commutator of small motors, but because AgFi has a low softening temperature, it tends to cause adhesion during rotation and sliding of the commutator. The disadvantages were that the contact resistance was high and the contact resistance was unstable.
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 overcome these drawbacks, and aims to provide a sliding contact material that has a high softening temperature and a low and stable contact resistance.
本発明の摺動接点材料は、Ａｇ中に、Ｗ、Ｖ。The sliding contact material of the present invention contains W and V in Ag.

, V, Ta, Nb in total of 0, 5 to 10
- The purpose of this addition is to increase the softening temperature of Ag to prevent the skin contact pieces on the outer periphery from adhering during rotation of the commutator of a small motor.
This is to make the contact resistance low and stable with little variation, 0.5'W/.

ばらつきが大きくなって不安定となる亀のである。If it is less than 10%, the effect of increasing the softening temperature of FiAg is small and the adhesion phenomenon of the contact piece can be prevented. The tortoise becomes unstable as the dispersion increases.

記の表の右欄に示すような結果を得′た。As shown in the drawings, a small motor with a diameter of 10 M and a length of Au-Ag-Cu was prepared using the sliding contact material of the embodiment of the present invention and the conventional sliding contact material having the composition shown in the left column of the table below.
When the diameter and length were determined to be 0.3 m and the length was determined, the results shown in the right column of the table below were obtained.

るものである。Test conditions Voltage: 12V Current: 250mA DC Commutator rotation speed: 2000rl) mAs is clear from the table above, the life of the contact piece on the outer periphery of the commutator in the conventional example ≠ the amount of wear F
Since the sliding contact material of the present invention has a high softening temperature, the contact pieces on the outer periphery of the commutator of a small motor made by kneading may stick together during sliding. The contact resistance is low and stable with little variation.
