Abstract

[목적] 3기통 엔진용의 크랭크 샤프트와 같이, 적절한 균형을 남기는 것을 필요로 하는 피시험체용의 균형시험기에 있어서, 복수종의 불균형을 간단한 조작에 의해 설정할 수 있는 시험기를 제공하는 것에 있다.[Objective] A balance tester for a test object, such as a crankshaft for a three-cylinder engine, that requires proper balance to be provided, wherein a tester capable of setting a plurality of types of imbalances by simple operation is provided.

[구성] 시험기의 기틀(10)에 스프링(8)에 의해 걸린 주형 진동대(4)에 크랭크 샤프트(1)의 외에, 제1불균형 부재로서의 중추(11a)를 구비한 제1더미 축(11)과 제2불균형 부재로서의 중추(12a)를 구비한 제2더미 축(12)을 회전가능하게 부착하고, 원 포지션 클러치(14)를 해체하여 제1더미 축(11)만을 회전시키는 제1종류의 불균형과, 원 포지션 클러치(14)를 접촉하여 양 더미 축(11), (12)을 함께 회전시키는 제2종류의 불균형을 간단한 조작으로 설정할 수 있도록 하였다.[Configuration] A first pile shaft 11 having a pivot 11a as a first unbalanced member, in addition to the crankshaft 1, on a mold shake table 4 fastened to the base 10 of the testing machine by a spring 8. And a second dummy shaft 12 having a pivot 12a as a second unbalanced member rotatably, and dismounting the one position clutch 14 to rotate only the first dummy shaft 11. The imbalance and the second kind of imbalance in which both the dummy shafts 11 and 12 are rotated together by contacting the one-position clutch 14 can be set by a simple operation.
