If a sintered bearing can be used instead of an expensive ball bearing, the ABS system can be constructed at a lower cost, but the load applied to the bearing of the automobile ABS system exceeds the load range of the conventional sintered bearing. In some cases, it is difficult to use.
- Fe-Cu based sintered bearings are used for the motor system bearings of automobile wipers. This is because the bearings used have become smaller and the load received by the bearings has increased due to the miniaturization of the motor system of automobile wipers.

Abstract
Description
Niは、Pと合金相を形成し、耐摩耗性向上や摩擦係数を低減させる作用がある。また、NiはCu、Sn、Pと素地の固溶体を形成し、軸受の強度を向上させ、時効硬化によりさらに軸受の強度を向上させることもでき、もって軸受の耐摩耗性向上に寄与する。
Snは、Cu、Ni、Pと素地の固溶体を形成し、軸受の強度を向上させ、時効硬化によりさらに軸受の強度を向上させることもでき、もって軸受の耐摩耗性向上に寄与する。Snの含有量が3%未満では所望の効果が得られず、一方その含有量が15%をこえても強度向上に効果がなく、かえって寸法精度が低下するので好ましくない。
Pは、Niと合金相を形成し、耐摩耗性向上や摩擦係数を低減させる作用がある。P含有量が0.5%未満では所望の効果が得られず、一方その添加量4.0%を超えても所望の効果向上が無く、かえって原料コストが高くなるので好ましくない。
固体潤滑剤は、軸受に優れた潤滑性を付与し、軸受の耐摩耗性の向上に寄与する。固体潤滑剤として、黒鉛、フッ化黒鉛、二硫化モリブデン、窒化ホウ素、フッ化カルシウム、タルク(Mg3Si4O10(OH)2)のうち少なくとも1種類以上を含有する。なお、タルクは焼結後にエンスタタイト(MgSiO3)となる。
Cu-Ni-Sn合金粉末に、Ni-P合金粉末又はCu-P合金粉末のいずれか一方、或いはNi-P合金粉末とCu-P合金粉末の両方を添加し、720~900℃範囲内の温度で焼結することにより、素地中にNiとPを主成分とした相が分散した金属組織を有するCu基焼結含油軸受が得られる。この金属組織は、素地の部分よりも硬度が高く、軸受の耐摩耗性に寄与する。
原料粉末として、粒径-100メッシュ以下のCu-Ni-Sn合金粉末(Ni及びSnの含有割合は表1に表示)、粒径-200メッシュのCu-8質量%P合金粉末、粒径-350メッシュのNi-11質量%P合金粉末、粒径200メッシュのSn粉末、及び平均粒径20μmの黒鉛粉末等の固体潤滑剤を用意した。これらの原料粉末を表2及び表3に示される成分組成となるように配合し、ステアリン酸亜鉛を0.5%加えてV型混合機で20分間混合し、200~700MPaの範囲内の所定の圧力でプレス成形してリング形状の圧粉体を製作した。この圧粉体を、天然ガスと空気を混合し、加熱した触媒に通すことで分解変成させたエンドサーミックガス(吸熱型ガス)雰囲気中で、720~900℃範囲内の所定の温度で焼結し、続いてサイジングを行い、Cu基焼結合金を得た。なお、得られたCu基焼結合金のうちのいくつかについては、続いて350℃×1時間の条件で時効処理を行った。そして、Cu基焼結合金中に潤滑油を含浸せしめた。以上の工程により、いずれも外径:18mm×内径:8mm×高さ:4mmの寸法のリング形状を有し、表2及び表3に示される組成成分のCu基焼結含油軸受を製作した。
得られた上記のリング形状のCu基焼結含油軸受(以下、リング状軸受という。)について耐摩耗試験を行った。それぞれのリング状軸受にS45Cのシャフトを挿入した。そして、リング状軸受の外側から、リング状軸受の半径方向(シャフトの軸方向に対して直角方向)に向けて面圧1.5MPaの荷重をかけながら、シャフトを100m/分で1,000時間回転させた。その後、リング状軸受の摺動面の最大摩耗深さとS45Cシャフトの摺動面の最大摩耗深さを測定し、耐摩耗性を評価した。
上記の方法で製作された本発明例のリング状軸受の断面について、電子線マイクロアナライザー(EPMA)を用いて、Sn、Ni、P、Cuの分布について分析を行った。分析条件は、加速電圧15kVに設定した。その結果を図1~3に示した。図1は、原料粉末にCu-Ni-Sn粉末、Cu-P粉末、黒鉛粉末を用いたときの断面組織、図2は、原料粉末にNi-P粉末を用いた本発明例20の断面組織、図3は、原料粉末にCu-Pを用いた本発明例4の断面組織である。図4は、原料粉末にCu-P粉末を用い、図3の場合と比較してPの含有量のみを減少させたときの断面組織である。図中、「SEI」と示したのは二次電子像、「COMPO」と示したのは反射電子組成像である。原料粉末にCu-P粉末を用いた場合、Ni-P粉末を用いた場合のいずれにおいても、素地中にNiとPを主成分とした相が分散した金属組織が存在することが確認された。なお、図4に示すように、Pが0%の場合には、上記金属組織は確認されなかった。
