Abstract
Description
그러나, 이러한 공지된 해결책은 특별히 각각의 평형추를 수용하도록 맞춰지는 풀리 및 플라이휠의 사용을 요구하며, 이로 인해 부품의 설계를 보다 복잡하게 하여 비용을 증가시키게 된다.
따라서, 본 발명의 목적은, 위에서 언급된 종래 기술보다 제조 비용이 낮고 보다 간단한 구조를 가지며, 축선 방향으로 최외각에 있는 저널의 외측에 배열되는 한 쌍의 평형추를 가지는 V형 내연기관용 크랭크샤프트를 제공하는 것이다.
Claims (5)
- 축선 방향으로 제 1 말단 경간을 한정하는 제 1 저널 쌍(21, 22),축선 방향으로 반대편 제 2 말단 경간을 한정하는 제 2 저널 쌍(23, 24),축선 방향으로 상기 제 1 및 제 2 말단 경간 사이에 위치되는 하나 이상의 중간 경간,각각 상기 제 1 저널 쌍(21, 22)의 최외각 저널(21) 및 상기 제 2 저널 쌍(23, 24)의 최외각 저널(24)에 결합되는 크랭크 암의 쌍(61, 69)으로서, 상기 크랭크 암의 쌍(61, 69)의 축선 방향 치수는 상기 말단 경간이 상기 하나 이상의 중간 경간의 길이와 실질적으로 동일한 길이(Y)를 갖도록 정해지는, 크랭크 암의 쌍(61, 69),크랭크샤프트(1)의 균형을 잡기 위해 각각 상기 크랭크 암의 쌍(61, 69)에 제공되는 제 1 및 제 2 평형추(61', 69'), 및상기 각각의 단부 저널(21, 24)의 외측에 배열되는 제 3 및 제 4 평형추(71, 72)를 포함하는, 내연기관용 크랭크샤프트(1)에 있어서,상기 제 3 및 제 4 평형추(71, 72) 중 하나(72)에 플라이휠을 직접 고정하도록 상기 평형추(72)에 고정부(80)가 형성되는 것을 특징으로 하는,크랭크샤프트.
- 제 1 항에 있어서,상기 제 3 및 제 4 평형추(71, 72)가 실질적으로 동일한 축선 방향 치수를 가지는,크랭크샤프트.
- 제 2 항에 있어서,상기 제 3 및 제 4 평형추(71, 72)의 축선 방향 치수가 상기 크랭크 암의 쌍(61, 69)의 치수와 실질적으로 동일한,크랭크샤프트.
