Zusammenfassung: | The present invention relates to a cooling device for a crank shaft, which comprises: a base frame (100); a rotation support block (200) rotatably coupled to the base frame (100) and in which an insertion groove (210) is formed at a point spaced apart from the center of rotation (o) of an upper surface by the distance (r) between shafts of a crankshaft (3a) and a crankpin (3b) of the crankshaft (3); a rotation driving unit (300) for rotating the rotation support block (200); and a proximity injection unit (400) coupled to one side of the base frame (100) to enable a grip operation that abuts against each other and surrounds an outer circumferential surface of the crankpin (3b), and injects a cooling medium to the outer circumferential surface of the crankpin (3b).
본 발명은 크랭크 샤프트용 냉각장치로서, 베이스프레임(100); 상기 베이스프레임(100) 상에 회전 가능하게 결합되고, 상기 크랭크 샤프트(3)의 크랭크축(3a)과 크랭크핀(3b)의 축간 거리(r)만큼 상면의 회전중심(o)에서 이격된 지점에 삽입홈(210)이 형성되는 회전지지블록(200); 상기 회전지지블록(200)을 회전시키는 회전구동부(300); 및 서로 맞닿아 상기 크랭크핀(3b)의 외주면을 감싸는 그립 동작이 가능하도록 상기 베이스프레임(100)의 일측에 결합되고, 상기 크랭크핀(3b)의 외주면에 냉각매체를 분사하는 근접분사부(400);를 포함한다. |
