The reason why the alloy material is made of an alloy material in which 0.5 to 10 weight % of at least one of Sn and Ti is added in addition to adding 0.5 to 5 weight % of Cu and 0.5 to 5 weight % of Cd is that The purpose is to increase the softening temperature during sliding to suppress stickiness and improve abrasion resistance. If it is less than 0.5% by weight, it cannot exhibit this effect, and if it exceeds 10% by weight, a large amount of oxides will be generated. , the contact resistance becomes high and it becomes unstable.

欄に示すような結果を得た。(Example and Conventional Example) Brush wires with a wire diameter of 0.7 mm made of an alloy material of A u 70% by weight - Pt 5% by weight - A g 10% by weight - Cu 14% by weight - Ni 1% by weight were each made into lengths of 8 cranes. Cut two pieces in parallel, and one end has a width of 10 m, a length of 13 N, and a thickness of 0.
．． A brush was made by welding two cranes to a composite material and bending a 2R arc-shaped contact part on the other end. On the other hand, the thickness 0 is made of the alloy materials of the embodiments and conventional examples of the composition shown in the left column of the table below.
．． A slip ring with a diameter of 50 cranes was made by punching out a 5 mm plate. 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 As is clear from the table above, the brushes and slip rings of the sliding contact devices of Examples 1 and 2 are better than the brush and slip ring of the sliding contact devices of Conventional Examples 1 and 2, respectively. It can be seen that the amount of wear is small 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 device of Example 1.2 is increased by adding at least one of Sn and Ti, 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.

ることのできる画期的なものと云える。(Effects of the Invention) As detailed above, the sliding contact device of the present invention has less wear on the brush, commutator, or slip ring than conventional sliding contact devices, and the contact resistance is equally low and stable. Therefore, it can be said to be an epoch-making device that can replace conventional sliding contact devices.
