摘　　要：为了优化圆弧端齿装配工艺,对圆弧端齿齿面加工偏差对齿面配合状态的影响机理进行了研究。根据圆弧端齿加工原理,研究了关键成型参数对齿面偏差的影响规律,建立了圆弧端齿装配初始齿面间隙模型,研究了齿面偏差对端齿盘装配初始齿面间隙的影响规律。理论研究和试验研究表明:齿面偏差是导致装配初始齿面间隙的直接原因。通过优化安装相位能使装配初始齿面间隙的均值减小18%,方差减小25%。为圆弧端齿连接结构装配精度形成原理与装配工艺优化研究提供基础,对于提高圆弧端齿连接的航空发动机转子装配品质具有重要的意义。In order to optimize curvic couplings assembly process,the influence of machining deviation of curvic couplings tooth surface on fitting state was theoretically studied.Based on the curvic coupling machining theory,the effect of key machining parameters on surface deviation was investigated.An assembly initial tooth surface clearance model of the curvic couplings was built.The effect of surface deviation on assembly initial tooth surface clearance of the curvic couplings was analyzed.According to theoretical and experimental study,tooth surface deviation directly caused the assembly initial tooth surface clearance.By optimizing the installation phase,the mean and variance of assembly initial tooth surface clearance can be reduced by 18%,and the variance can be reduced by 25%. The work provides afoundation for the principle of the assembly accuracy formation and parameter optimization of curviccouplings, contributing to assembly quality improvement of aero-engine rotors connected by curviccouplings.
