Abstract
【解決手段】 リング状素材の内径に転動部品が転動する転動部6を有する転動部品である機械部品7の製造において、転動部6を形成しようとするリング状素材の内径2aの面に素材の降伏応力の1.5倍以上の圧縮の静水圧応力を付与し、かつ、機械部品7である転動部品の転動方向への塑性ひずみが圧縮となる鍛造加工を行うことにより、リング状素材の内径2aの面に転動部品が転動する転動部6を形成することからなる転動疲労寿命に優れた転動部6を有するリング状の機械部品7の製造方法である。
【選択図】 図1
Description
すなわち、この転動部を形成しようとするリング状素材内径面に、圧縮の静水圧応力を付与して鍛造加工することにより、鋼中の非金属介在物と母相である鋼との界面に存在する空隙が閉鎖する方向へ向かうこととなり、転動疲労寿命に優れた機械部品を製造することができる。
鍛造加工時に少なくとも素材の降伏応力の1.5倍の圧縮の静水圧応力を付与させて転動面を形成することで、鋼中に含有する非金属介在物を母相である鋼との界面に存在する空隙を閉鎖して、転動疲労寿命に優れた機械部品を製造することができる。
