【発明の詳細な説明】
（産業上の利用分野）
本発明は、整流子面を研磨してその被膜を除去し、凹凸
を修正するクリーニングブラシに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cleaning brush that polishes a commutator surface to remove its coating and correct irregularities.
（従来の技術）
回転電機では、整流子面が黒化したり整流子面の凹凸が
大きいと、整流性能を低下させ、ブラシ摩耗及び整流子
摩耗を大きくする。(Prior Art) In a rotating electrical machine, if the commutator surface becomes black or has large irregularities, the rectification performance will be reduced and brush wear and commutator wear will increase.
従来、整流子面の過剰被膜を除去する目的でシリカ等の
研磨性を有する微細な粉末を少量ブラシ中に分散させた
所謂クリーナーブラシが用いられていた。Conventionally, so-called cleaner brushes have been used in which a small amount of abrasive fine powder such as silica is dispersed in the brush for the purpose of removing excess coating on the commutator surface.
（発明が解決しようとする問題点）
しかし上記クリーナーブラシは、整流子面の凹凸を修正
するまでには至らず、又前記研磨性を有する粉末は微細
なため（ミクロン以下）に凝集シ易く均一分散が困難で
あるという欠点があった。(Problems to be Solved by the Invention) However, the above-mentioned cleaner brush does not correct the unevenness of the commutator surface, and since the abrasive powder is fine (micron or less), it easily aggregates and becomes uniform. The drawback was that it was difficult to disperse.
本発明は、上記欠点を解消し、整流子面の凹凸修正も可
能なりリーニングブラシを提供することを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide a leaning brush that eliminates the above-mentioned drawbacks and allows correction of irregularities on the commutator surface.
（問題点を解決するだめの手段）
本発明は、アルミナを主成分とする研磨粉を３０〜５０
重量％含有させてなるクリーニングブラシ（以下ブラシ
と呼ぶ）に関する。(Another means to solve the problem) The present invention uses polishing powder containing alumina as a main component at a polishing rate of 30 to 50%.
% by weight (hereinafter referred to as a brush).
本発明において、溶融アルミナからなる研磨粉及びその
粒度について特に制限はないが、ビトリファイド研削砥
石に使われる溶融アルミナ粉で。In the present invention, there are no particular restrictions on the polishing powder made of fused alumina and its particle size, but the fused alumina powder used in vitrified grinding wheels may be used.
粒度は１０００番程度が好ましい。The particle size is preferably about No. 1000.
ブラシ中の研磨粉の含有量が３０重量％未満では、整流
子面の凹凸を修正するためには不十分であり、５０重量
％を越えると整流子を削りすぎて好壕しくない。If the content of abrasive powder in the brush is less than 30% by weight, it is insufficient to correct irregularities on the commutator surface, and if it exceeds 50% by weight, the commutator will be ground too much, which is not desirable.
ブラシの材質に制限はない。本発明のブラシは例えば次
のような方法で製造される。天然黒鉛粉をフェノール樹
脂ワニスで混練し、乾燥して溶剤を除去し、粉砕後前記
研磨粉を加えて混合して成形粉とし、公知の方法で成形
し焼成する。There are no restrictions on the material of the brush. The brush of the present invention is manufactured, for example, by the following method. Natural graphite powder is kneaded with phenolic resin varnish, dried to remove the solvent, and after pulverization, the abrasive powder is added and mixed to form a molding powder, which is then molded and fired by a known method.
上記のようにして研磨粉が均一に分散したブラシ材が得
られる。As described above, a brush material in which polishing powder is uniformly dispersed can be obtained.

により取り付けた。Example 1 Ceylon scale graphite powder of 100 mesh or less refined to an ash content of 0.5% by weight and HP-607N (trade name of novolac type phenolic resin manufactured by Hitachi Chemical Co., Ltd.) were mixed and placed in a kneader. After adding methanol as a solvent and kneading, the solvent was removed using an infrared dryer.
Grind to 0 mesh or less. The powder obtained in this way has 9 particles of 1000 molten alumina powder (JISR6
Fused alumina powder for 210 vitrified grinding wheel)
was added to the brush so that it contained 40% by weight, and mixed in a type 2 mixer to obtain a molded powder. Put this molding powder into the mold of a powder molding press 1. After molding at a pressure of Of 2 /cm2, it was fired at 650°C in a nitrogen gas atmosphere, and then cut into the shape and dimensions of a brush, and lead wires were attached with copper powder fasteners.
