摺動接点装置を提供せんとするものである。The present invention has been made to eliminate such drawbacks, and provides a sliding contact device that improves the wear resistance and contact resistance characteristics of brushes and improves the wear resistance of commutators or slip rings. It is something that I try to do.

At least one of Sn and Ti is added in an amount of 0.5 to 1. The reason why the alloy material is made of an alloy material with the addition of p d
0.5% by weight to prevent softening during sliding due to precipitates in order to improve the adhesion resistance of the -Ag -Cu alloy material.
If the amount is less than 1%, the effect cannot be exhibited, and if it exceeds 1%, the amount of oxides generated increases, the contact resistance becomes high, and the vertical stability becomes unstable.

The reason why the alloy material is made of 12% by weight or less than 3% to 12% by weight of Ag-Cu and 5% by weight of Cd is to suppress the stickiness when sliding with the brush and improve wear resistance.
If the content is less than 3% by weight, the effect cannot be obtained;
If the Cd content exceeds 5% by weight, the amount of oxide generated during sliding will be too large, resulting in high and unstable contact resistance.If the Cd content exceeds 5% by weight, when this becomes oxidized Cd, the contact resistance will increase. This increases the wear resistance and deteriorates the wear resistance. Therefore, the content of Cu is 3 to 12% by weight, and the content of Cd is not more than 5% by weight.
次に本発明による摺動接点装置の具体的な実施例と従来

果を得た。In the left column of Table 1 below, brush wire rods with a wire diameter of 0.7 mm made of alloy materials of the example and conventional example with the indicated compositions are each cut into lengths of 8 ml, two wires are placed in parallel, and one end is cut. Width 10m
Welded to a composite material of m, JFc size 13 + n, thickness 0.2 sheets □
Then, a 2R arc-shaped contact part was curved on the other end to make a brush. On the other hand, a sling ring with a diameter of 50 mm was made by punching out a 0.5 mm thick plate made of an alloy material having the composition shown in the right column of Table 1 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. The wear amount and contact resistance were measured, and the results shown in Table 2 below were obtained.

100g ・Sliding time near h (blank below) Table 2 As is clear from Table 2 above, the brushes and slip rings of the sliding contact devices of Examples 1 to 3 are the same as those of conventional examples 1 and 2, respectively. It can be seen that the amount of wear is significantly less than that of the contact brush and slip ring, and the contact resistance is much lower (and more stable). This is because the addition of at least one of Go, Sn, and Ti prevents the material from softening during sliding and improves adhesion resistance, and the slip ring of the sliding contact device of Examples 1 to 3 This is because the alloy material that makes up the material, Cu, suppresses the increase in tackiness during sliding and improves the abrasion resistance.

できる画期的なものと云える。As detailed above, the sliding contact device of the present invention has significantly superior wear resistance of the brush and commutator or slip ring compared to conventional sliding contact devices, generates extremely little wear powder, and has contact resistance. It is also much lower and more stable, so it can be said to be an epoch-making device that can replace conventional sliding contact devices.
