According to the lumped mass method, this study presents a bending axial–torsional coupled dynamic model of a dual-branch transmission system with offset nonorthogonal spur (ONS) face gear pairs. The common form and force of the ONS face gear pair, the layout form of the dual-branch transmission system, and meshing phase differences are investigated in detail. The dynamic model considers factors, such as meshing phase differences, meshing stiffness, installation errors, damping, and elastic deformations. Results show that the dynamic uneven load of the system is affected by the meshing phase differences and gear vibrations when no installation error occurs. The input load and torsional stiffness have a crucial effect on the dynamic load sharing coefficients when installation errors exist. Moreover, the support stiffness of the spur cylindrical pinion 1 and the meshing stiffness fluctuation amplitude of each gear pair should be smaller.
