u8-12% by weight, Ag27-33% by weight, Cu1
The reason why it is made of an alloy material containing 2 to 16% by weight and 0.1 to 2% by weight of Zn is to take advantage of its excellent spring properties.

る。In addition, in the composition of the commutator or slip ring material, the reason for adding 0.1 to 5% by weight of C to Ag is as follows.
This is to improve wear resistance by suppressing adhesion during scraping operations, and if it is less than 0.1% by weight, this effect will not be apparent, and if it exceeds 5% by weight, processing will become difficult. Furthermore, Si
The reason for adding 0.5 to 10% by weight of Zr in total is as follows.
The purpose is to increase the softening temperature during the rubbing action with the brush and improve wear resistance, and if it is less than 0.5% by weight, the effect cannot be achieved, and if it exceeds 10% by weight, the amount of oxides generated increases. The contact resistance becomes high and, moreover, it becomes unstable.

２Ｒの円弧状の接触部を曲成してブラシを作った。A brush was made by welding a composite material with a length of 13 m and a thickness of 0.2 tm, and bending a 2R arc-shaped contact portion at the other end.

定した処、下記の表の右欄に示すような結果を得た。On the other hand, a slip ring with a diameter of 50 m was made by punching out a plate material of 0.5 fi thickness made of the materials of the example and conventional example having the compositions shown in the left column of the table below. Therefore, a sliding contact device was made by combining these brushes and slip rings, each brush was brought into contact with the slip ring, and the slip ring was rotated in forward and reverse directions to conduct a friction test under the following test conditions to determine the wear of the brushes and slip rings. When the amount and contact resistance were measured, the results shown in the right column of the table below were obtained.

100g Sliding operation time = 7 hours As is clear from the table above, the brushes and slip rings of the sliding contact devices of Examples 1 to 3 are different from the brushes and slip rings of conventional examples 1 and 2, respectively. It can be seen that the amount of wear is small and the contact resistance is low and stable. This is because the material constituting the slip ring of the sliding contact devices of Examples 1 to 3 has improved wear resistance due to the suppression of adhesion by C and the increase in softening temperature by adding Si and Zr. This is because the amount of oxide generated during the sliding operation is in balance with the amount of wear.

It can be said that it can replace the sliding contact device.
