轮缘(又称加强环或轮箍)是航空发动机薄壁壳体组件所不可缺少的零件,主要起支撑、加强等作用(参看图7)。轮缘加工质量的好坏,直接影响到与简体的组装、焊接等工序的进行。如何保证轮缘加工质量、与简体组合达到最佳的装配状态、寻求一种既合理可靠又简便 Rims (also known as reinforcement rings or wheel hubs) are indispensable components for aero-engine thin-walled housing components that primarily support, reinforce, etc. (see Figure 7). Rim processing quality is good or bad, a direct impact on the simplified assembly, welding and other processes. How to ensure the quality of rim processing, and simplified combination to achieve the best assembly state, to seek a kind of reasonable and reliable and easy
