Abstract

PURPOSE:To obtain a material for a brush contact having superior wear resistance and generating little noise by adding restricted amounts of Sn and other specified element to an Au-Pt-Pd-Ag-Cu-Zn material for a brush contact as a base material. CONSTITUTION:An alloy material consisting of, by weight, 9-11% Au, 9-11% Pt, 34-36% Pd, 29-31% Ag, 13-15% Cu and 0.5-1.5% Zn is used as a base material. A material for a brush contact is obtd. by adding 1-10wt% Sn and 0.5-3wt% one or more among Te, Sr and Zr to the base material without changing the ratio in the composition. To the base material may be further added 0.01-0.5wt% Fe group metal.

This caused noise.

The present invention aims to provide a sliding contact material with improved wear resistance by using the alloy material as a base material and adding a small amount of a specific element to the alloy material.

~31% by weight, Cu13~15%, Zn0.5
~1.5% by weight of Sn and Te, Sr, Zr without changing the composition ratio.
The reason why 0.5 to 3% by weight of at least one of Sn and Te is added is to improve the wear resistance of the alloy material.
This is to disperse and harden intermetallic compounds with Sr and Zr.
1% by weight of Sn or Te, Sr.

Ｚ、ｒの少なくとも一種が０．５重量％未満ではその効

Ｓｒ、Ｚｒの少なくとも一種が３重量％を超えると酸化

安定となるものである。If at least one of Sr and Zr exceeds 3% by weight, the amount of oxides generated will increase, contact resistance will increase, and furthermore, it will become unstable.

また、前記合金材料にＳｎを１り１０重量％とＴｅ。Further, the alloy material contains 1% Sn, 10% by weight of Te, and 10% by weight of Te.

れ以上の効果が得られないからである。The reason for adding 0.5 to 3% by weight of at least one of Sr and Zr and further adding 0.01 to 0.5% by weight of PC group metal is to refine the crystal grains and further improve wear resistance. This is because if the content is less than 0.01% by weight, the effect of grain refinement will not be obtained, and if it exceeds 0.5% by weight, no further effect will be obtained.

次に下記の左欄に示す成分組成の本発明による摺動接点

接触部を曲成して刷子接点を作った。Next, using the sliding contact material according to the present invention and the conventional sliding contact material having the compositions shown in the left column below, each wire diameter was 0.7 mm.
Brush wire rods were made and cut into lengths of 8 ml+ each.
Two brush contacts were made by arranging them in parallel and welding one end to a composite material with a width of 10 mm, a length of 13 mm, and a thickness of 0.2 m + i, and bending an arc-shaped contact portion of 2 R on the other end to make a brush contact.

The results shown in the column were obtained.

0g Test time: 7 hours (blank below) As is clear from the table above, the brush contacts of Examples 1 to 6 had significantly less wear than the conventional brush contacts, and the contact resistance was low and stable. I understand.

上してい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 G is Sn, Tc, and Sr.
This is because the dispersion of the intermetallic compound with Zr hardens and improves wear resistance. Especially Examples 2, 5.6
The reason why the amount of wear of the brush contact of Embodiment 1゜3.4 is even smaller than that of the brush contact of Example 1゜3.4 is that Fe group metal is added to the sliding contact material of the present invention constituting the brush wire. This is because the crystal grains have become finer and more dispersed, further improving wear resistance.

The amount of abrasion powder generated is extremely small, there is almost no noise generated, and it is possible to obtain a brush contact having a lower (stable) contact resistance than when using conventional sliding contact materials.
