Abstract

Using a one-way clutch has been reported to be very effective in reducing the vibration of gear pairs. However, study on the effect of using a one-way clutch has been based on numerical analysis only, and no experimental study has yet been executed. Hence, in this study, experiments to verify the effectiveness of using a one-way clutch to reduce the torsional vibration have been executed. Dynamic responses over a wide range of speeds have been compared for various numbers and positions of the clutch. The results of the experiments verified that a one-way clutch is effective in reducing the vibration by decreasing the tooth mesh vibration as well as the vibration transmitted from the input shaft.

기어열의 입력축이나 출력축에 원웨이클러치를 설치하면 기어열의 진동을 효과적으로 감소 시킬 수 있다고 보고된 바 있으나, 아직까지 수치적 해석만이 행하여졌고 실험에 의한 검증이 이루어지지 않았다. 따라서 본 연구에서는 원웨이클러치를 가지는 기어열을 대상으로 동특성 실험을 수행하여, 원웨이클러치가 진동 감소에 효과적인지 여부의 타당성을 검증하였다. 클러치 설치 유무와 설치 위치에 따른 차이를 비교하기 위하여, 입력축과 출력축에 각각 클러치 설치 조건을 달리하면서 넓은 속도 범위에 걸쳐서 동특성을 측정 비교하였다. 실험 결과에 의해, 클러치가 기어물림 진동뿐만 아니라 입력축에서 전달되는 진동을 감소 시킴으로써, 기어열의 비틀림 진동 감소에 효과적임을 확인하였다.
