Claims (6)
- 소재 준비 단계와, 소재에 치형을 절삭하여 복수의 기어치(21)를 가지는 기어 반제품을 제조하는 단계(ST-110, 치형 절삭 단계)와, 치형 절삭된 기어 반제품을 열처리하는 단계(ST-120, 열처리 단계)와, 열처리 된 기어 반제품을 전조하는 단계(ST-130, 전조 단계)로 이루어지며; 상기 치형 절삭된 기어 반제품(20)의 기어치(21)에는 원주 방향 양측으로 여유살부(28)가 구비되며, 상기 전조 단계(ST-130)에서는 전조 다이에 의하여 여유살부(28)가 가압되어 기어 반제품이 기어로 제조되며; 상기 여유살부(28)의 두께(t)는 피치원에서 최대가 되도록 형성되는 것을 특징으로 하는 기어 제조 방법.
- 제1 항에 있어서, 상기 여유살부(28)의 두께(t)는 피치원에서 이끝원과 이뿌리원으로 갈수록 감소하는 것을 특징으로 하는 기어 제조 방법.
- 제1 항에 있어서, 제조되는 기어는 인버류트 기어이고, 상기 여유살부(28)는 이끝원에서 기초원까지의 범위에서 구비되는 것을 특징으로 하는 기어 제조 방법.
- 제1 항에 있어서, 상기 여유살부(28)의 두께(t)는 피치원에서 100∼200㎛ 범위로 형성되는 것을 특징으로 하는 기어 제조 방법.
- 제1 항에 있어서, 상기 여유살부(28)의 두께(t)와 열처리 단계 후의 경도는 반비례 관계를 가지도록, 기어 반제품에 여유살부(28)가 형성되는 것을 특징으로 하는 기어 제조 방법.
- 제1 항 또는 제4 항에 있어서, 상기 열처리 단계(ST-120)에서는 열처리 단계(ST-120) 후의 기어 반제품의 여유살부(28)의 표면 경도가 기어 최종 경도의 70∼85% 범위가 되도록 열처리되는 것을 특징으로 하는 기어 제조 방법.
