摘　　要：对某型号发动机用圆柱滚子主轴承在安装内圈组件时,运转出现卡滞的问题进行了分析。通过建立模型、仿真分析和试验验证,指出了轴承运转出现卡滞是由轴承内圈退刀槽尺寸设计不合理以及制造精度超差所造成的。对该轴承结构退刀槽尺寸进行设计改进,改进后轴承再生产时,严格控制退刀槽加工尺寸和精度,装机后再没有出现滚子与滚道卡滞,运转不灵活的问题。It takes the analysis of seizing up of cylindrical roller master bearing which used for fitting engine inner ring assembly during running.By building up model,simulating analysis,testing and verifying,it indicats that seizing up of bearing during running is caused by unreasonable dimension design of inner ring escape and out-of-tolerance of manufacturing precision.The design improvement for dimension of bearing structure escape has been made.After improvement,machining dimension of escape and precision for the newly manufactured bearing has been strictly under control.After installation on engine,the seizing up between roller and roll-away nest as well as inflexible turn have not been occurred anymore.
