改gai換huan鏈lian要yao齒chi盤pan時shi，誤wu將jiang失shi園yuan公gong平ping的de齒chi盤pan裝zhuang到dao摩mo托tuo車che上shang

，致zhi使shi鏈lian條tiao忽hu緊jin忽hu鬆song，檢jian驗yan與yu調tiao節jie時shi
，巧qiao遇yu鬆song的de一yi端duan，另ling一yi端duan則ze過guo緊jin。不bu論lun以yi上shang哪na種zhong緣yuan由you致zhi鏈lian條tiao調tiao節jie過guo緊jin，都dou會hui因yin而er而er大da大da降jiang低di鏈lian條tiao和he齒chi盤pan的de運yun用yong壽shou命ming。當dang鏈lian條tiao調tiao節jie過guo緊jin時shi，因yin與yu齒chi盤pan的de接jie觸chu壓ya力li增zeng大da
，鏈lian條tiao易yi拉la長chang，鏈lian節jie板ban易yi變bian形xing或huo拉la斷duan，鏈lian條tiao滾gun柱zhu也ye會hui因yin而er而er破po碎sui。除chu此ci之zhi外wai
，齒chi盤pan也ye會hui因yin而er磨mo損sun而er過guo早zao地di使shi齒chi形xing變bian尖jian，嚴yan重zhong時shi呈cheng鋸ju齒chi狀zhuang。
