从RB211-535E4发动机高压定位轴承传动轴组件的结构特点出发,重点研究了装配时经常出现跳动量测试不合格的原因,提出了自主创新的排故方案,该方案已在实际排故中得到应用,不仅可以挽救变形的零件,节约维修成本,还能显著缩短修理周期,成为解决N3振动和防止周期延误的有效措施之一。
Starting from the structural characteristics of RB211-535E4 engine high-pressure positioning bearing shaft assembly, this paper focuses on the reasons of unbearable jerk test during assembly, and puts forward an independent innovation troubleshooting plan, which has been applied in the actual troubleshooting , Not only can save the deformation of the parts, saving maintenance costs, but also significantly reduce the repair cycle, as a solution to N3 vibration and prevent cycle delays, one of the effective measures.
