本発明は、小型モータの整流子外周に摺接する刷子接点
の刷子板材を作る摺動接点材料の改嵐に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to reforming a sliding contact material for making a brush plate material of a brush contact that slides on the outer periphery of a commutator of a small motor.

ある。In the sliding contact material of the present invention, the addition of at least one of Mu, Ag, Pt, Pd, Ru, and Rh in a total of 0.5 to 10 weights to the copper bronze causes oxidation. Nah @
The addition of these noble metals, which are resistant to oxidation, suppresses the oxidation of Cu during sliding, and the oxidized C prevents high contact resistance from becoming unstable, as well as improving wear resistance. If the weight is less than 0.5%, there is no effect, and if it exceeds 10%, the spring properties of the brush plate material will deteriorate.

After mK cutting, the brush plate material 2 of the brush contact 3, which is made by holding one brush plate material 2 as shown in the figure, is cut to a thickness of 12 m on the outer periphery.
Three IIa pieces 1a made of Ag-Cu1O wt. A commutator rotation test was conducted at , and the wear amount and contact resistance of the brush plate material 2 of the brush contact 3 were measured, and the results shown in the right column of the table below were obtained.

The wear amount of the brush plate material of the conventional example was 40 to 60 fi, while the wear amount of the brush plate material of the example was 20 to 25 μm, which was significantly reduced and showed excellent wear resistance. I understand. This is simply because the brush plate material of the example contains a precious metal that does not oxidize or does not oxidize, suppressing the oxidation of Cu during sliding, and reducing the amount of Cu oxide produced.

果がある。As detailed above, the sliding contact material of the present invention has Au, Ag, Pt, Pd, Ru, and Rh added to copper bronze to suppress oxidation and reduce the amount of Cu oxide produced. The brush plate material of the brush contact made from this K has the excellent effect that the sliding contact material is low and stable, and wear resistance is significantly improved.
