Claims (6)
- 異なる径(D)の段部(2)を順次設けた段付きシャフトとして構成されているシャフト(1)のシャフト段付部に圧縮残留応力を導入する方法であって、
前記シャフトは、それぞれ隣接し合う段部(2)の間に径移行部(3)が配設されており、前記径移行部(3)を、最後の焼き戻し処理を行なった後に、圧縮残留応力を導入することが可能な温度に制御しつつ急冷する方法において、
前記最後の焼き戻し処理を行なった後に加熱および急冷の別個の熱処理を行い、その熱処理温度は、前記最後の焼き戻し処理の温度以下に選定されることを特徴とする方法。 - 径移行部(3)に、急冷を行なうために、急冷媒体を噴霧する、請求項1に記載の方法。
- 径移行部(3)に、急冷を行なうために、浸漬工程によって冷却する、請求項1に記載の方法。
- 径移行部(3)が、仕上げの最終輪郭(7)を考慮して備えさせたゆとり(8)をもって形成されており、仕上げの最終輪郭(7)を形成する際に、急冷を行なった後に、熱処理輪郭(6)を除去する、請求項1から3のいずれか一つに記載の方法。
- シャフト(1)の仕上げの最終輪郭(7)を考慮したゆとり(8)が、仕上げ時に、最大で10ないし40mmの値を有する、請求項4に記載の方法。
- 径移行部(3)が、その熱処理輪郭(6)において、25ないし50mmの値(R)を持つ半径を有している、請求項4または5に記載の方法。
