本発明は金属黒鉛質電刷子成形用組成物に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metal graphite electric brush forming composition.
金属黒鉛質電刷子は耐摩耗性、耐衝撃性、耐蝕性、低電
気損失等が要求され、従来までは銅を主体として黒鉛５
〜１５重量％、潤滑剤として鉛を５〜１０重量％、機械
的強度を高めるために錫を５〜１０重量％、他に亜鉛等
の添加物を少量添加した高金属黒鉛質電刷子が使用され
てきた。Metal-graphite electric brushes are required to have abrasion resistance, impact resistance, corrosion resistance, and low electrical loss.
~15% by weight, 5-10% by weight of lead as a lubricant, 5-10% by weight of tin to increase mechanical strength, and a small amount of other additives such as zinc. It has been.
しかし近年鉛は公害の問題より使用できない機種があら
れれ、しか敏集電環の高周速化、大電流化が進み従来の
電刷子では大電流による発熱、また発熱による潤滑不足
および電刷子本体の集電環面への溶着によって電刷子摩
耗が増大する欠点があった。However, in recent years, lead cannot be used in some models due to pollution problems, and as the speed of the sensitive current collection ring increases and the current increases, conventional electric brushes generate heat due to large currents, and lack of lubrication due to the heat generation. There was a drawback that the wear of the electric brush increased due to welding of the electric brush to the current collecting ring surface.
本発明はかかる欠点の々い金属黒鉛質電刷子を提供する
ことにある。The object of the present invention is to provide a metal graphite electric brush which is free from such drawbacks.
本発明は燐成分が０．１〜０．５重量％になるように燐
化合物、二硫化モリブデンまたは二硫化タング７テンＯ
１・５〜３重量％、錫５重量％以下、残部黒鉛および銅
からなる金属黒鉛質電刷子成形用組成物に関する。The present invention uses a phosphorus compound, molybdenum disulfide or tungsten disulfide so that the phosphorus content is 0.1 to 0.5% by weight.
The present invention relates to a metal-graphite electric brush forming composition comprising 1.5 to 3% by weight of tin, 5% by weight or less of tin, and the balance graphite and copper.
さらに詳しくは本発明は公害の問題のある鉛含有を皆無
にし、これに伴う潤滑効果の低下を黒鉛の増量、二硫化
モリブデンまたは二硫化タング７テンの添加で補おうと
するものである。More specifically, the present invention attempts to completely eliminate the presence of lead, which poses a pollution problem, and to compensate for the resulting decrease in lubricating effect by increasing the amount of graphite and adding molybdenum disulfide or tungsten disulfide.
なお本発明において二硫化モリブデンまたは二硫化タン
グ７テンの添加量は０．５〜３重量％とされる。In the present invention, the amount of molybdenum disulfide or tungsten disulfide added is 0.5 to 3% by weight.
０．５重量％未溝の場合は効果が表われず、また３重量
％を越えると集電環面に傷が発生する。If the amount is 0.5% by weight without grooves, no effect will be exhibited, and if it exceeds 3% by weight, scratches will occur on the current collecting ring surface.
また錫は機械的強度の向上には有効であるが３０Ａ／ｃ
ｒ１１以上になると電刷子本体が集電環面に溶着するだ
め５重量％以下とされる。Also, tin is effective in improving mechanical strength, but at 30A/c
If it exceeds r11, the electric brush body will be welded to the current collecting ring surface, so the amount should be 5% by weight or less.
錫の減量による機械的強度の補充として燐成分が０．１
〜０．５重量％になるような燐化合物を添加し、焼結時
の脱酸効果によって機械的強度を向上させる。The phosphorus content is 0.1 to supplement the mechanical strength due to the reduction of tin.
A phosphorus compound is added in an amount of ~0.5% by weight to improve mechanical strength through deoxidizing effect during sintering.
燐化合物としてはＣｕ３ Ｐｅ ５ｎＰｔ ＡｇＰ等が
使用され特に制限はたい。As the phosphorus compound, Cu3Pe5nPtAgP, etc. can be used, and there are no particular restrictions.
以下本発明の詳細な説明する。The present invention will be explained in detail below.

その結果も合わせて第１表に示す。The results are also shown in Table 1.
なお摩耗量は１００時間当りの摩耗を示し、集電環面は
試験終了後の観察結果を示す。Note that the amount of wear indicates the wear per 100 hours, and the current collecting ring surface indicates the observation results after the end of the test.

面に溶着したり集電環面に傷がつく等の欠点が生じた。On the other hand, the electric brushes obtained using the conventional material compositions shown as comparative examples had a large amount of wear, and samples A1 and A1
Those other than No. 5 had low mechanical strength, and some of them had drawbacks such as welding to the current collecting ring surface or scratches on the current collecting ring surface.
また試料Ａ１の従来材と試料ＡＩ ２の本発明の組成物

係について検討を行なった。Further, the relationship between the current density and the wear amount of the electric brushes obtained using the conventional material as Sample A1 and the composition of the present invention as Sample AI2 was investigated.
その試験結果を第１図に示す。The test results are shown in Figure 1.

刷子摩耗量もほとんど変化がなかった。As a result, in the electric brush obtained using the composition of the present invention of sample AI2, no welding phenomenon was observed even under high current density, and the amount of wear of the electric brush was almost unchanged.
これに対し試料Ａ１の従来材の組成物を用いて得られた
電刷子は大電流密度下で溶着現象が発生し、電刷子摩耗
量が増大する欠点が生じた。On the other hand, the electric brush obtained using the conventional material composition of Sample A1 had the disadvantage that a welding phenomenon occurred under a large current density and the amount of wear of the electric brush increased.
