本発明は、電機用ブラシの整流性能及び耐摩耗性の改良
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improving the rectifying performance and wear resistance of brushes for electrical machinery.
最近の車両用主電動機は、チョッパー制御回生制動等に
より電動機の整流条件が著しく苛酷になっている。その
ため整流子のブラックバー、段摩耗等の損傷が発生し、
ブラシの摩耗を大きくしている。これらの整流子の損傷
、ブラシ摩耗の増大等の問題はブラシの整流性能の違い
によっても大きく左右される。In recent vehicle traction motors, commutation conditions for the motor have become extremely severe due to chopper control regenerative braking and the like. As a result, damage such as black bars and step wear on the commutator occurs.
This increases brush wear. These problems such as commutator damage and increased brush wear are largely influenced by differences in the commutating performance of the brushes.
本発明は、このような問題点を解決し、整流子の損傷、
ブラシ摩耗の少ない電機用ブラシを提供 □することを
目的とする。The present invention solves these problems and prevents commutator damage,
The purpose is to provide electrical brushes with less brush wear.

存させた電機用ブラシに関する。The present invention relates to a brush for electrical machinery in which a thermosetting resin and an organic lubricant coexist in the pores.
本発明において熱硬化性樹脂はフェノール樹脂。In the present invention, the thermosetting resin is a phenolic resin.
−フラン樹脂等であるが耐熱性の点でフラン樹脂が好ま
しい。有機質潤滑剤としてはヤシ油、鯨油。-Furan resin etc., but furan resin is preferable in terms of heat resistance. Coconut oil and whale oil are organic lubricants.
桐油等の油脂、ハラフィン、ワックス、パルミチン酸ナ
トリウム等の高級脂肪酸塩などが好ましい。Preferred are fats and oils such as tung oil, halafine, wax, and higher fatty acid salts such as sodium palmitate.
ブラシ素材としては電気黒鉛質のものが潤滑性。The brush material is made of electrographite, which has good lubricity.
純、度等を加味また整流性能の点で好ましい。It is preferable in terms of purity, degree, etc., and rectification performance.

5 as a thermosetting resin, furan resin (trade name VF-302, manufactured by Hitachi Chemical), and coconut oil as an organic lubricant. Put the carbon brush material into the impregnating pot, and add it to the impregnating pot.
The pressure was reduced to 11TllHg, and in this state, the above furan resin was poured into the impregnation pot.

The pressure was reduced to about 1.5 g, and a 2% by weight toluene solution of coconut oil was injected into the solution to impregnate it. Remove this from the impregnation pot and bring it to 110℃.
Drying was carried out for 3 hours. In this way, a brush with the desired furan resin and coconut oil coexisting in its pores was manufactured.

ラシは従来品に比較して著しく小さいことがわかった。Table 1 shows the measurement results of rectification performance and brush wear using a practical machine. Figure 1 shows the brushes of the conventional product and the example.
This is rectification band data obtained using a 0KW vehicle traction motor. It can be seen that the rectifying zone of the electric brush 2 of the present invention is wider than the rectifying zone 1 of the conventional non-impregnated product.1 The electric brush of the present invention has a high rectifying ability and produces fewer black bars on the commutator. Figure 2 shows the results of a brush abrasion test using a 100-seat main motor, and it was found that the amount of abrasion of the electric brush of the present invention was significantly smaller than that of conventional products.
