Abstract

PURPOSE:To obtain a sliding contact material with a raised softening temp., improved wear resistance and contact resistance characteristics by adding a specified percentage of one or more among Co, Sn and Ti to an Au alloy material contg. a prescribed percentage each of Pt, Ag, Cu and Ni. CONSTITUTION:A sliding contact material is obtd. by adding 0.5-15wt% one or more among Co, Sn and Ti to an Au alloy material consisting of, by weight, 69-71% Au, 4-6% Pt, 9-11% Ag, 13-15% Cu and 0.5-1.5% Ni without changing the ratio in the composition. The sliding contact material is much superior to a conventional sliding contact material in wear resistance, and it produces a very small amount of powder owing to wear and generates hardly noise. The sliding contact material gives a brush contact having more stable contact resistance than a brush contact made of the conventional sliding contact material.

温度が低いため整流子との摺動時に凝着しやすく、摩耗
性が生じ易く、接触抵抗の不安定の原因となっていた。However, brush contacts made of this alloy material have a low softening temperature, so they tend to stick together when sliding with the commutator, causing abrasion and causing instability in contact resistance.

The present invention aims to provide a sliding contact material with improved wear resistance and contact resistance characteristics by adding a specific material to the alloy material as a base material to increase the softening temperature.

る。The sliding contact material of the present invention contains 69 to 71% by weight of Au, Pt
An alloy material consisting of 4 to 6% by weight, 9 to 11% by weight of Ag, 13 to 15% by weight of Cu, and 0.5 to 1.5% by weight of Ni,
It is made by adding 0.5 to 10% by weight of at least one of Co, Sn, and Ti without changing the composition ratio.

, Pt4-6% by weight, Ag9-11% by weight, Cu13-
15% by weight of Co, Sn, and Ti without changing the composition ratio.
The reason for adding 0.5 to 15% by weight of at least one of the following is to increase the softening temperature in order to improve the wear resistance and contact resistance stability of the alloy material, and if it is less than 0.5% by weight, It is not effective in preventing adhesion by increasing the softening temperature,
If it exceeds 15% by weight, the amount of oxides generated will increase, contact resistance will increase, and furthermore, it will become unstable.

。Next, using the sliding contact material according to the present invention and the conventional sliding contact material having the compositions shown in the left space below, a diameter of 0.7 mm was obtained, respectively.
Brush wire rods were made, each cut into 8 mm lengths, and 2
These are lined up and one end has a width of 10 mm, a length of 13 mm, and a thickness of 0.
．． A brush contact was made by welding to a 2 mm base material and bending a 2R arc-shaped contact part at the other end. Then, each brush contact was brought into contact with a disc-shaped commutator, and the commutator was rotated in forward and reverse directions to conduct a sliding test under the following test conditions, and the amount of friction and contact resistance were measured. We obtained the results shown in the figure.

試験条件 電流：０．６Ａ 電圧：１２Ｖ 負荷：抵抗負荷 回転速度：１０００ｒｐｍ 周速：１３０〜１２０ｍ／ｍｉｎ 接触力：１００ｇ 試験時間：７時間 上記の表で明らかなように実施例１〜３の刷子接点は従

耗性、接触抵抗の安定性を向上するからに他ならない。This is because the sliding contact material of the present invention constituting the brush wire of the brush contacts of Examples 1 to 4 is made of Co, Sn, and Ti.
The reason for this is that the addition of 20% prevents adhesion due to softening during sliding and improves wear resistance and stability of contact resistance.
