Description
最初に本発明の一実施の形態の動力伝達部品の構成について説明する。本発明の一実施の形態の動力伝達部品として、ギヤおよびカムが挙げられる。
図3を参照して、本発明の一実施の形態の動力伝達部品の製造方法においては、まず原料粉末準備工程(S10)が実施される。この工程(S10)では、動力伝達部品の材料として、鉄を主成分とする原料粉末が準備され、混合される。鉄を主成分とする原料粉末は、たとえばSUS316L(JIS規格)および2%Ni(ニッケル)含有鉄合金である。その他、必要に応じて銅や二硫化モリブデン、黒鉛などの粒子を配合することもできる。
粉末プレス焼結法で微細な原料粉末をそのままプレス成形すると、摩擦損失により成形性が悪化する。本発明の一実施の形態の動力伝達部品によれば、鉄を主成分とする原料微粉末を造粒した造粒粉がプレス成形され、かつ焼成された焼結材からなっている。粉末プレス焼結法で造粒粉をプレス成形することにより、金型内での原料粉末の流動性を向上することができるので成形性を向上することができる。よって、微細な原料粉末を用いることができるので、原料粉末の表面積の増加に伴って隣接粉との焼結性を向上することができる。これにより、高密度の焼結材を得ることができる。
表1に示す材料および試料作製条件において、本発明の実施例として実施例1の試料および実施例2の試料、従来例として従来例1の試料をそれぞれ複数作製した。
