为解决由于发动机机匣同轴度不合格引起发动机转、静子碰摩而发生的振动问题,阐述了某型航空发动机机匣同轴度的测量原理和方法,提出了相应的不合格机匣同轴度调整办法和解决措施。多次排故结果表明:车削安装边、选配偏心环等方法对于解决不同轴引起的发动机偏摩问题有重要作用。
In order to solve the vibration problem caused by the engine rotation and stator rubbing due to the unacceptable coaxiality of the engine casing, the measuring principle and method of the coaxiality of a certain aero-engine casing are expounded. The corresponding unqualified casing Axis adjustment methods and solutions. Repeated troubleshooting results show that: turning the edge of the installation, optional eccentric ring and other methods for solving the problem of eccentric shaft engine caused by the partial friction plays an important role.
