Ag8 Ni2wt%, Cu12-16wt%, Nt
The reason why it is made of an alloy material containing 01 to 2% by weight is to take advantage of its excellent spring properties.
また、コンミテータ又はスリップリング材の構成におい

及びＳｎを合計で０．５〜１０重量％添加した理由は、
ブラシとのすり動作時の耐摩耗性を向上すべく潤滑剤と

多くなり、接触抵抗が高くなり、その上不安定となるも
のである。In addition, the reason why 0.5 to 5% by weight of C was added to Ag in the composition of the commutator or slip ring material was as follows.
This is to suppress stickiness during scraping operations and improve wear resistance; if it is less than 0.5% by weight, this effect will not be apparent, and if it exceeds 5% by weight, processing will be difficult. Furthermore, In
The reason for adding 0.5 to 10% by weight of Sn in total is as follows:
This is to generate an appropriate amount of oxide that acts as a lubricant to improve the wear resistance during rubbing action with the brush. If it is less than 0.5% by weight, the amount of oxide generated is small and it cannot be effective as a WRHk agent. First, if it exceeds 10% by weight, the amount of oxides generated will increase, contact resistance will increase, and furthermore, it will become unstable.

-Brush wires made of an alloy material of 14% by weight of Cu and 1% by weight of Ni and each having a wire diameter of 0.7mm are cut into lengths of 8m,
A brush was made by arranging two brushes in parallel, welding one end to a composite material of width 10fi, length 13fi, and thickness 0.2cm, and bending a 2R arc-shaped contact part at the other end. On the other hand, a thickness of 0.5 mm made of the materials of the embodiments and conventional examples having the component compositions shown in the left column of the table below.
A slip ring with a diameter of 50 m was made by punching out a 5 fl plate. 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 Sliding time Near time As is clear from the table above, the brushes and slip rings of the sliding contact devices of Examples 1 to 3 have a greater amount of wear than the brushes and slip rings of the sliding contact devices of Conventional Examples 1 and 2, respectively. It can be seen that the contact resistance is low and stable. This is because the material constituting the slip ring of the sliding contact devices of Examples 1 to 3 has improved wear resistance due to the suppression of adhesion by C and the lubricating effect of In and Sn oxides generated during sliding operation. In addition, since the oxide is soft, it is easily removed by rubbing action, and the contact surface of the slip ring is always clean, resulting in low contact resistance.

It can be said that it can replace the sliding contact device.
