Description
dm:パイプ素材の外径
ds:絞り成形後の外径
一般に、ロータリースウェージングやリンクタイプスウェージング(絞り率の大きな中空軸製品に適した加工法である。)の場合、絞り率δが一工程で50%以上の絞りが可能であると言われているが、実際には、絞り率δが60%を越えると、材料コストや熱処理コスト(焼鈍等の前処理が必要になる。)が高くなり、また、加工性を過度に優先させると製品機能を満足できない可能性が有る。一方、絞り率δを低くおさえ、かつ、必要な軸剛性を確保するために、等速自在継手のサイズを必要以上に大きくしなければならない場合もあり、装着スペース、重量の増大となって、設計上不利な点が出てくる。
