Description
【発明の詳細な説明】 この発明は平板型整流子装置に関するものである。[Detailed description of the invention] The present invention relates to a flat plate commutator device.
従来の平板型整流子装置の平面図を第１図に示し、その
断面図を第２図に示す。A plan view of a conventional flat plate commutator device is shown in FIG. 1, and a sectional view thereof is shown in FIG.
これらの図において、合成樹脂製の絶縁体１上に、銅箔
の上に貴金属めっきをして構成されるセグメント２がス
リット３により３分割されて貼着されている。In these figures, a segment 2 made of precious metal plating on copper foil is adhered to an insulator 1 made of synthetic resin, divided into three by slits 3.
このセグメント２上を刷子４の分岐刷子片４ａ、４ｂが
摺動するようになっている。Branched brush pieces 4a and 4b of the brush 4 are configured to slide on this segment 2.
このようにして構成される従来の整流子は、第３図に示
すように、合成樹脂製の絶縁体１に銅箔２ａを貼着した
のち、分岐刷子片４ ａ 、４ ｂが摺動するセグメン
ト２上に、第４図のように、貴金属めっき（Ｐｄまたは
Ｒｈめっき）２ｂをして耐アーク性および耐摩耗性を高
めていた。In the conventional commutator constructed in this way, as shown in Fig. 3, after a copper foil 2a is attached to a synthetic resin insulator 1, branched brush pieces 4a and 4b are slid. As shown in FIG. 4, noble metal plating (Pd or Rh plating) 2b was applied to the segments 2 to enhance arc resistance and wear resistance.
また、第５図に示すように、刷子４についても同様にリ
ン青銅またはベリリウム銅製のばね材５の摺動面に貴金
属（ＲｈまたはＰｄ）６をクラッドして用いていた。Further, as shown in FIG. 5, the brush 4 was similarly used by cladding the sliding surface of a spring material 5 made of phosphor bronze or beryllium copper with noble metal (Rh or Pd) 6.
そのため、コストが高くなるという問題があった。Therefore, there was a problem that the cost was high.
ところで、このような構造の平板型整流子装置は、外周
側に位置する分岐刷子片４ａの摺動距離が内周側の分岐
刷子片４ｂの摺動距離よりも大きいため、外周側の分岐
刷子片４ａおよび外周側のセグメント２０部分の摩耗が
激しく内周側の摩耗が少ない。By the way, in the flat plate type commutator device having such a structure, since the sliding distance of the branched brush pieces 4a located on the outer circumferential side is larger than the sliding distance of the branched brush pieces 4b on the inner circumferential side, the sliding distance of the branched brush pieces 4a on the outer circumferential side The piece 4a and the segment 20 portion on the outer circumferential side have severe wear, and the inner circumferential side has less wear.
したがって、この発明の目的は、セグメントトよび刷子
の外周側摺動面の硬度のみを高めることによりコストの
安い平板型整流子装置を提供することである。Therefore, an object of the present invention is to provide a flat plate type commutator device that is inexpensive by increasing the hardness of only the outer peripheral sliding surfaces of the segments and brushes.
この発明による平板型整流子装置の一実施例の要部、す
なわち、整流子ブロックの平面図を第６図に示す。FIG. 6 shows a plan view of a main part of an embodiment of a flat plate type commutator device according to the present invention, that is, a commutator block.
図において、整流子ブロック７のセグメント８の外周側
部分８ａにＰｄまたはＲｈのような高価なめっきをして
硬度を高め、内側部分８ｂにはＡｇのような受画なめっ
きをしている。In the figure, the outer peripheral side portion 8a of the segment 8 of the commutator block 7 is plated with expensive material such as Pd or Rh to increase hardness, and the inner portion 8b is plated with a non-reflective material such as Ag.
そのほかの部分は第１図のものと同じである。Other parts are the same as those in Figure 1.
また、刷子についても、第７図に示すように、ばね材９
の一部分にＲｈまたはＰｄのような貴金属１０をクラッ

１１ｂをもつ刷子１１を形成している。Also, regarding the brush, as shown in FIG.
A part of the branched brush piece 11a as shown in FIG. 8 is clad with a noble metal 10 such as Rh or Pd.
11b is formed.
この分岐刷子片１１ａの摺動面は貴金属１０によって構
成されている。The sliding surface of this branched brush piece 11a is made of noble metal 10.
そして、この分岐刷子片１１ａが第６図のセグメント８
の外周側部分を摺動するように、刷子１１を整流子ブロ
ック７に配設して平板型整流子装置が構成される。This branched brush piece 11a is the segment 8 in FIG.
A flat plate commutator device is constructed by disposing the brush 11 on the commutator block 7 so as to slide on the outer peripheral side of the brush 11 .
このように、セグメント８釦よび刷子１１の外周側部分
８ａ、１１ａのみに高価な貴金属めっきまたは貴金属１
０をクラッドして硬度を高めその摩耗度が内周側摺動面
とほぼ同一になるように構成するため、従来例に比べて
コストが安くなる。In this way, expensive precious metal plating or precious metal 1 is applied only to the outer circumferential portions 8a and 11a of the segment 8 button and the brush 11.
0 is clad to increase the hardness so that the degree of wear is almost the same as that of the inner sliding surface, so the cost is lower than that of the conventional example.
以上のように、この発明の平板型整流子装置は、セグメ

動面と内周側摺動面とほぼ同一になるようにするため、
コストが安くなる。As described above, in the flat plate type commutator device of the present invention, the hardness of the outer sliding surfaces of at least one of the segments and brushes is increased by 1 the hardness of the inner sliding surfaces, so that the degree of wear is lower than that of the outer sliding surfaces. In order to make the surface almost the same as the inner sliding surface,
Cost is lower.
