Abstract

본 발명은 아이들텐숀풀리(6)에 동력전달수단(10)에 의해 그 회전력이 전달되어 반추형의 바란스추(20)를 구동토록 설치되어, 크랭크샤프트의 양측에 나란히 샤프트등을 설치하지 않고 아이들텐숀폴리에 간단히 취부하여 소정의 2차진동 저감효과를 가질 수 있다.In the present invention, the rotational force is transmitted to the idle tension pulley (6) by the power transmission means (10) so as to drive the rumble type balance weight (20), and the shafts and the like are not provided on both sides of the crankshaft It can be easily attached to the tensile sheath to have a predetermined secondary vibration reduction effect.

따라서, 기존 유통된 엔진에도 개조업이 설치가 가능하고, 생산원가 및 공정수, 부품수가 크게 절감되어 제작자 및 그 사용자로 하여금 경제적인 이익을 줄 수 있다.Therefore, it is possible to install a new operation even in a conventional engine, and the production cost, the number of steps and the number of parts can be greatly reduced, thereby allowing the manufacturer and the user to economically benefit.

또, 엔진의 중량을 경감시킬 수도 있는 등의 매우 유용한 발명인 것이다.It is also a very useful invention that the weight of the engine can be reduced.
