Description
このような焼結含油軸受については、低摩擦係数を長期にわたって維持することが求められ、金属マトリックス(特許文献1等)、もしくは潤滑油(特許文献2等)について様々な提案が為されている。また近年では、いずれか一方の改良のみならず、金属マトリックスの組成と、このマトリックスに好適な潤滑剤の組み合わせにまで踏み込んだ提案(特許文献3等)がなされている。
原料粉末として、粒度100メッシュ以下のアトマイズ銅粉、P含有量が0.5質量%で残部がCuおよび不可避不純物である粒度100メッシュ以下のアトマイズ銅燐合金粉、粒度200メッシュ以下のアトマイズ錫粉、平均粒径10μmのニッケル粉末および黒鉛粉末を用意した。これらの原料粉末を表1に示す比率で配合し、混合した各粉末を成形圧力200MPaで内径φ10mm、外径φ16mm、全長10mmの円筒形状に圧粉成形した。得られた圧粉体はアンモニア分解ガス雰囲気中において780℃で焼結を行った。焼結を行った後に再圧を行い、軸受試験試料とした。試料にはパーフルオロポリエーテルを含浸した。使用した含浸油のパーフルオロポリエーテルは、エヌ・オー・ケー・クリューバー(株)製のKF1391(商品名)である。
平均粒径が2〜100μmのニッケル粉末を用意した。また第1実施例で用いたアトマイズ銅粉、アトマイズ錫粉を用意した。用意したアトマイズ銅粉末にアトマイズ錫粉末:10質量%、平均粒径の異なるニッケル粉末:6質量%を配合し、混合した各粉末を用い、第1実施例と同じ条件で成形、焼結、再圧、含浸工程を行い軸受試験試料を作製した。
第1実施例で作製した試料番号07の試料と同じ粉末、添加量、試料作製条件で軸受試料を作製し、環境温度を変えて軸受試験を行い軸受摩耗量を測定した。この結果を表3に示す。
