摘要

In order to implement the uniform load distribution of the gear train with dual power split, first, a pseudo-static model is built. Next, according to the closed-loop characteristics of system power flow, the conditions for the deflection compatibility of torsional angle are proposed, which are then combined with the moment equilibrium conditions and the elastic support conditions to calculate the transmission torque of each gear pair with the help of the equivalent mesh error theory and the equivalent mesh stiffness theory. Finally, the load-sharing coefficient of the system is obtained and the influences of the installation and manufacturing errors of each component on the power split are analyzed based on the statics theory. The results show that the above-mentioned errors collectively influence the load-sharing characteristics, and that the reduction of a single error is ineffective in achieving perfect load-sharing characteristics.
