摘要：
Considering the support deformation of the casing, shafting and bearing, the equivalent misalignment of the spiral bevel gear was calculated under actual conditions. Firstly, the static analysis of the casing was carried out by commercial software ANSYS, and the axial equation of the input and output shafts under the loading condition was obtained by the least square optimization method. Then, the force analysis of the gears was performed, and the displacement of the shaft and bearing nodes was calculated by the one-dimensional finite element method. The equivalent misalignment amount was obtained by superposition of two groups of deformation. The tooth contact analysis (TCA) model considering the misalignment amount was established, and the optimized machining parameters were acquired by the redesign of the tooth surface. Result showed that under the condition of deformation forming equivalent misalignment, the contact patterns would get close to the center of the tooth surface when the gear was loaded, and the meshing quality can be improved. © 2018, Editorial Department of Journal of Aerospace Power.
