A study on vibration characteristics caused by backlash of gear-box in escalator with chain-sprocket drive mechanism

체인-스프라켓 메커니즘을 갖는 에스컬레이터에서 기어박스 백래시로 인한 이상진동에 관한 연구

This paper presents an improved escalator dynamic model so as to reflect the experimental observation on the pseudo-resonance affected by load applied. The experimental evidence reveals that backlash of gearbox as well as sag of driving chain are most critical factors to the pseudo-resonance in escalators. The dynamic model effectively reflects vibration characteristics measured in real escalators with respect to different conditions of driving chain and the number of passengers. (omitted)
