航空发动机机匣同轴度的测量与调整

为排除航空发动机振动故障,从某型航空发动机机匣同轴度检测原理入手,研究机匣同轴度的检测机理,针对机匣同轴度不合格故障提出调整与解决措施。制定出选配偏心环、机匣安装边位移铰孔及车削机匣安装边等多种故障修复方法,通过机匣位移铰孔、调整选配偏心环、增设自动化电动测具等改进措施,达到提高机匣同轴度测量精度,保证发动机装配质量要求。

Measurement and Adjustment of Aeroengine Casing Concentricity

In order to exclude an aeroengine vibration failure, the mechanism of casing concentricity was investigated. Focus on the failure of the casing concentricity, many methods were proposed to eliminate the failure, such as matching eccentric ring, edge displacement reaming casing installation and turning casing installation side. The measurement precision are improved and the quality of engine assembly are ensued by reaming displacement, adjusting the matching eccentric ring and adding an electric automated measurement tool.
