Description
本発明は、前記課題にかんがみてなされたもので、軟質層から基層内まで疲労破壊が伝播することを防止できる技術を提供することを目的とする。
(1)第1実施形態:
(1−1)摺動部材の構成:
(1−2)計測方法:
(1−3)摺動部材の製造方法:
(2)他の実施形態:
(1−1)摺動部材の構成:
図1は、本発明の一実施形態にかかる摺動部材1の斜視図である。摺動部材1は、裏金10とライニング11とオーバーレイ12とを含む。摺動部材1は、中空状の円筒を直径方向に2等分した半割形状の金属部材であり、断面が半円弧状となっている。2個の摺動部材1が円筒状になるように組み合わせることにより、すべり軸受Aが形成される。すべり軸受Aは内部に形成される中空部分にて円柱状の相手軸2(エンジンのクランクシャフト)を軸受けする。相手軸2の外径はすべり軸受Aの内径よりもわずかに小さく形成されている。相手軸2の外周面と、すべり軸受Aの内周面との間に形成される隙間に潤滑油(エンジンオイル)が供給される。その際に、すべり軸受Aの内周面上を相手軸2の外周面が摺動する。
(1−2)計測方法:
上述した実施形態において示した各数値を以下の手法によって計測した。
摺動部材1の各層を構成する元素の質量は、ICP発光分光分析装置(島津社製ICPS−8100)によって計測した。
まず、裏金10と同じ厚みを有する低炭素鋼の平面板を用意した。
次に、低炭素鋼で形成された平面板上に、ライニング11を構成する材料の粉末を散布する。具体的に、上述したライニング11における各成分の質量比となるように、Cuの粉末とBiの粉末とSnの粉末とを低炭素鋼の平面板上に散布した。ライニング11における各成分の質量比が満足できればよく、Cu−Bi,Cu−Sn等の合金粉末を低炭素鋼の平面板上に散布してもよい。粉末の粒径は、試験用ふるい(JIS Z8801)によって150μm以下に調整した。
次に、中空状の円筒を直径方向に2等分した形状となるように、Cu合金層が形成された低炭素鋼をプレス加工した。このとき、低炭素鋼の外径が摺動部材1の外径と一致するようにプレス加工した。
前記実施形態においては、エンジンのクランクシャフトを軸受けするすべり軸受Aを構成する摺動部材1を例示したが、本発明の摺動部材1によって他の用途のすべり軸受Aを形成してもよい。例えば、本発明の摺動部材1によってトランスミッション用のギヤブシュやピストンピンブシュ・ボスブシュ等を形成してもよい。むろん、摺動部材1は、軸以外の相手材が摺動する部材であってもよい。また、ライニング11のマトリクスはCu合金に限られず、相手軸2の硬さに応じてマトリクスの材料が選択されればよい。また、軟質材料はマトリクスよりも軟らかく、かつ、マトリクス中に析出可能な材料であればよく、例えばPb,Sn,Inであってもよい。また、界面Xに必ずしもBiの酸化膜が形成されなくてもよく、例えばオーバーレイ12を電気めっきする際の印加電圧を大きく設定することにより、ライニング11のBi粒子11bからBiがエピタキシャル成長することを防止してもよい。
