In this study, a gearbox and blade were modeled in the MASTA program, and the housing and carrier components were modeledusing a finite element method. Using substructure synthesis, all the components were combined and used to establish a vibration model of a2.5-MW wind turbine gearbox. In addition, the safety displacement factor was evaluated using an AGMA data sheet about bearing’s outer race forthe input shaft and output shaft. As a result, the bearing’s outer race for the input shaft, and the radial and axial responses were satisfied by the1st and 2nd planetary gears and the 3nd helical gear transmission error(TE), respectively. However, theoutput shaft support bearing’s outer raceresponses were not satisfied with the radial response by the 2nd TE and axial response by the 3rd TE. To reduce the vibration, tooth modificationwas needed. After profile tooth modification, at the outer race of the output shaft support bearing, the radial response was reduced by approximately20μm, and the axial response was reduced by approximately 6μm.
