In order to implement the uniform load distribution of the gear train with dual power spliting

a pseudo-static model was built firstly.And then

according to the system power flow closed-loop feature

the torsional angle deformation compatibility conditions were deduced

the moment equilibrium conditions and elastic support conditions was established to calculate each gear pair transmission torque

and finally the system load sharing coefficient was obtained.Next

the relationship of the installation error and system load sharing characteristics was analyzed in the static research

and the floating pinion based on clearance floating played an important role in the system load sharing. The results show that the clearance of 0.8mm could meet the pinion to floating under the influence of the gear 2 with installation error of 0.03mm

obtain the load sharing coefficient of 1.0038

the floating pinion can improve the load sharing characteristics. Through theoretical data compared with the experimental data

in the same error conditions

power distribution is respectively 53.88% and 53.50%

which verifies the correctness of the method proposed.
