理由は、優れた耐食性を活かすためである。In the sliding contact device of the present invention, the reason why the brush is made of the same alloy material as conventional brushes, which is 30 to 50% by weight of Au, 20 to 40% by weight of Ag, and 20 to 40% by weight of Pd, is because of its superior properties. This is to take advantage of its corrosion resistance.

In addition to adding 0.5 to 5 weight % of Cu and 0.5 to 5 weight % of Cd, 0.1 to 2 weight % of at least one of W, V, and Mo is added.
The reason why it is composed of an alloy material made of additives is to increase the softening temperature when sliding with the brush and improve wear resistance.
If it is less than 0.1% by weight, the effect cannot be exhibited, and if it is less than 2% by weight.
If it exceeds this, the amount of oxides generated will increase, the contact resistance will increase, and furthermore, it will become unstable.

If it is less than 0.01% by weight, the effect of grain refinement will not appear, and if it is more than 0.5% by weight, the effect of grain refinement will not appear. However, no further effect can be obtained.

た。On the other hand, a slip ring with a diameter of 50 tm was made by punching out a 0.5 mm thick plate made of an alloy material having the composition shown in the left hand side of the table below. Therefore, a sliding contact device was made by combining these brushes and slip rings, and a sliding test was conducted under the following test conditions by bringing each brush into contact with the slip ring and rotating the slip ring in forward and reverse directions. When we measured the amount of wear and contact resistance, we obtained the results shown in the right column of the table below.

100g Sliding time Near 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 the same as 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 than that of a ring, and the contact resistance is equally low and stable. This is because the softening temperature of the alloy material constituting the slip ring of the sliding contact devices of Examples 1 to 4 is increased by the addition of at least one of W, V, and Mo, and stickiness during sliding is suppressed. This is because the wear resistance is improved and the amount of oxides generated during sliding is balanced with the amount of wear. In particular, the reason why the slip ring of the sliding contact device of Example 4 has even less wear than the slip rings of other sliding contact devices is because the material composing the slip ring has F.
This is simply because the e-group element is added and its crystal grains are finely dispersed, resulting in improved wear resistance.
