Abstract
In order to reveal the mechanism of loading sharing among star gears of star gear trains in geared turbofan (GTF) engine, a meshing error analysis was conducted on the eccentricity error, gear thickness error, base pitch error, assembly error, and bearing manufacturing error of gear components of the star gear trains respectively, and the floating meshing error resulting from meshing clearance variation caused by the simultaneous floating of sun gear and annular gear was considered. A refined mathematical model of loading sharing coefficient calculation was established in consideration of displacement compatibility, the calculated load sharing coefficient of two condition was 1.0505 and 1.0452, and the characteristic curve of load sharing was obtained, providing a scientific theory evidence for proper tolerance distribution and control in design and process.
