The present invention relates to a sliding contact device, and particularly to improvements in the materials of the brush, commutator, or slip ring that constitute the sliding contact device. Conventional sliding contact device is made of Au8~12wt%, Pt8
A brush composed of an alloy material of ~12% by weight, Pd33-37% by weight, Ag28-32% by weight, Cu12-16% by weight, Zn0.1-2% by weight, and Ag-Cd0.5-15% by weight.
This is a combination of a commutator or a slip ring made of an alloy material. By the way, since the brush of this sliding contact device is made of the above-mentioned alloy material, when it slides with the commutator or the slip ring, it tends to generate abrasion powder, making the contact resistance unstable. On the other hand, the commutator or slip spring is
It was composed of an alloy material containing 0.5 to 15% by weight of Ag-Cd, and had high adhesiveness and poor abrasion resistance when sliding with a brush. The present invention has been made in order to eliminate such drawbacks, and provides a sliding contact device in which the wear resistance and contact resistance characteristics of the brush are improved, and the wear resistance of the commutator or spring is improved. It is something to do. The sliding contact device of the present invention has a composition ratio of Au8 to 12% by weight, Pt8 to 12% by weight, Pd33 to 37% by weight, Ag28
~32wt%, Cu12~16wt%, Zn0.1~2wt%
Au-Pt-Pd-Ag-Cu-Zn is 95-99.5% by weight
and the balance is composed of an alloy material containing at least one of Al, Ga, Mn, and Ni in a total of 0.5 to 5.0% by weight, and Ag-Cu3 to 12% by weight or Ag-Cu3.
It is a combination of a commutator or a slip ring made of an alloy material containing up to 12% by weight and up to 5% by weight of Cd. In the sliding contact device of the present invention, the composition ratio of the brush is 8 to 12% by weight of Au, 8 to 12% by weight of Pt, and 33 to 37% by weight of Pd.
Weight%, Ag28~32wt%, Cu12~16wt%,
Au-Pt-Pd-Ag-Cu-Zn with Zn0.1~2wt%
The reason why the alloy material is composed of 95 to 99.5% by weight and the balance of at least one of Al, Ga, Mn, and Ni in a total of 0.5 to 5.0% by weight is that the Au-Pt-Pd-Ag
-To improve adhesion resistance in order to improve contact resistance characteristics and wear resistance of Cu-Zn alloy materials, Al,
If the total amount of at least one of Ga, Mn, and Ni is less than 0.5% by weight, the effect cannot be exhibited, and if it exceeds 5% by weight, the amount of oxides generated increases, contact resistance becomes high, and it becomes unstable. It is something. Ag-
The reason why it is made of an alloy material of 3 to 12% by weight of Cu or 3 to 12% of Ag-Cu to 5% by weight of Cd is to suppress the stickiness when sliding with the brush and improve wear resistance. If the Cd content is less than 3% by weight, the effect cannot be obtained, and if it exceeds 12% by weight, the amount of oxide generated during sliding becomes too large, resulting in high contact resistance and instability. If it exceeds % by weight, when it becomes oxidized Cd, the contact resistance increases,
Abrasion resistance deteriorates. Therefore, the content of Cu is 3 to 12% by weight, and the content of Cd is 5% by weight.
It was designed not to exceed. Next, specific embodiments and conventional examples of the sliding contact device according to the present invention will be described. Brush wire rods with a wire diameter of 0.7 mm made of alloy materials of the example and conventional example shown in the left column of Table 1 below were each cut into lengths of 8 mm, and two wire rods were placed in parallel with one end having a width of 10 mm and a length of 8 mm. A brush was made by welding it to a base material with a length of 13 mm and a thickness of 0.2 mm, and bending a 2R arc-shaped contact part on the other end. On the other hand, slip rings with a diameter of 50 mm were made by punching out 0.5 mm thick plates made of alloy materials having the compositions shown in the right column of Table 1 below. Therefore, a sliding contact device was made by combining these brushes and slip rings, respectively.
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 of the brush and slip ring were measured, and the results are shown in Table 2 below. We obtained the results shown below. Test conditions Current: DC 0.6A Voltage: 12V Load: Resistance load Rotation speed: 1000 rotations/divided speed: 130 to 120m/min Contact pressure: 100g Contact time: 7 hours

的なものと云える。[Table] As is clear from Table 2 above, the brushes and slip rings of the sliding contact devices of Examples 1 to 13 have a greater amount of wear than the brushes and slip rings of the sliding contacts of Conventional Examples 1 and 2, respectively. It can be seen that the contact resistance is much lower and more stable. This is because the alloy material constituting the brushes of the sliding contact devices of Examples 1 to 13 is suppressed from softening during sliding by Al, Ga, Mn, Ni, etc., and its adhesion resistance is improved. As a result, wear resistance is improved. In addition, since the slip rings of the sliding contact devices of Examples 1 to 13 are made of Cu, which is an alloy material, the increase in stickiness during sliding is suppressed and the wear resistance is improved. No. 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.
