In order to ensure the sprag one-way clutch two shafts assembly have good dynamic performance, a four-degree of freedom lateral-torsional coupling dynamic model was established by the lumped parameter method.The method of Runge Kutta was used to solve the nonlinear dynamic system equations.The effect of the sprag one-way clutch torsional stiffness and torsional damping on the dynamic transmission error and dynamic load of the gear pair was studied.And the effect of the contact ratio of the gear pair on the dynamic windup angle, the maximum impact force and the steady contact force of the sprag one-way clutch was studied also.The results show that: ① The dynamic transmission error and the meshing force of the gear pair decreases with the sprag one-way clutch torsional stiffness at the lower range of excitation frequencies, and it is vice verse at the higher range of excitation frequencies.② The dynamic transmission error and the meshing force of the gear pair decreases with the sprag one-way clutch torsional damping.③ The dynamic windup angle, the maximum contact force, the steady contact force of the sprag one-way clutch increases the contact ratio of the gear pair.
