ある。In the sliding contact device of the present invention, the brush is made of 8 to 12% by weight of Au, 8 to 12% by weight of Pt, and 8 to 12% of Pd as the conventional brush.
33-37% by weight, Ag28-32% 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.

と加工が困難となるものである。In addition, in the composition of the commutator or slip ring material, the reason why 0.5 to 15% by weight of Cd oxide is uniformly and finely dispersed in Ag is to increase the lubricity and improve the wear resistance of Ag. If it is less than 0.5% by weight, it has no effect, and if it exceeds 15% by weight, the contact resistance becomes high and unstable. Furthermore, N b r I n l B
The reason for uniformly and finely dispersing at least one of the oxides of 0.5 to 10% by weight is to increase the softening temperature, suppress stickiness during the rubbing operation, and improve wear resistance.
If the amount is less than ii% by weight, the effect will be weak, and if it exceeds 10% by weight, processing will become difficult.

すような結果を得た。On the other hand, a thickness of 0.5 mm made of the materials of the example (by internal oxidation method) and the conventional example of the component composition shown in the left column of the table below.
A slip ring with a diameter of 50 m was made by punching out a crane board. 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 Near sliding time (blank below) As is clear from the table above, the brushes and slip rings of the sliding contact devices of Examples 1 to 4 are different from the brushes and slip rings of the sliding contact devices of Conventional Examples 1 and 2, respectively. It can be seen that the amount of wear is less and the contact resistance is equally low and stable. This is because the material constituting the slip ring of the sliding contact devices of Examples 1 to 4 has the lubricating effect of Cd oxide and the N

ならない。This is because the abrasion resistance is improved by suppressing adhesion by the Ba oxide, and since these oxides are uniformly and finely dispersed, they do not accumulate and the contact resistance is low and stable.
