为支撑我国齿轮传动涡扇发动机研制,针对五路分流人字齿星型风扇驱动齿轮箱,对影响均载系数的各项加工及装配误差进行分析并建立了星型齿轮传动系统静态均载系数计算模型。计算并分析了某星型齿轮传动系统试验件静态均载系数,得到了各项加工及装配误差的敏感度分析结果,提出了通过调整行星轮偏心相位进而降低静态均载系数的方法,并以某星型齿轮传动系统试验件为例,对装配过程中如何进行行星轮偏心相位同步进行了说明。
In order to support the development of the Geared turbofan (GTF) engine in China, the five-branch-power-split herringbone star gearbox for Fan drive gear system(FDGS) is studied. The manufacturing and assembling errors that affects the load sharing coefficient of the star gear system are analyzed. The calculation model for static load sharing coefficient of the star gear system is established. By calculating and analyzing the static load sharing coefficient of a star gear system test piece, the sensitivity of the manufacturing and assembling errors is obtained, the method of reducing the static load sharing coefficient by adjusting offset phase of star gears is proposed, and how to synchronize the eccentricity phase of planetary gear during assembly process illustrated by a star gear system test piece.
