摘要
本文通过对异响发动机零件的交叉验证,最先锁定导致发动机平衡轴异响的相关零件平衡轴和滚针轴承。146/160阶次啸叫跟随滚针轴承,212阶次啸叫跟随平衡轴平衡轴。然后通过鱼骨图分析方法和异响发动机、非异响发动机零件的差异对比找出平衡轴系统鬼阶啸叫的根本原因,平衡轴滚针轴颈波纹度差是引起174/212阶次啸叫的主要原因;滚针波纹度差引起146/160阶次啸叫的主要原因。最后提出解决措施即优化零件波纹度,优化后零件通过试验验证,平衡轴系统鬼阶啸叫消失,问题解决。
Through cross validation of engine components with abnormal noise,this article first identifies the relevant components that cause the engine balance shaft abnormal noise,including the balance shaft and needle roller bearings.The 146/160 order howling follows the needle roller bearing,and the 212 order howling follows the balance shaft balance shaft.Then,by using the fishbone diagram analysis method and comparing the differences between noisy and non noisy engine parts,the fundamental reason for the ghostly howling of the balance shaft system was identified.The difference in the waviness of the balance shaft needle roller neck was the main cause of the 174/212 order howling;The main reason for the 146/160 order whistling caused by the difference in needle roller ripple.Finally,a solution was proposed,which is to optimize the waviness of the parts.After optimization,the parts were verified through experiments,and the ghostly howling of the balance shaft system disappeared.The problem was solved.
