The deformation compatibility equations and the torque balance equations of star gearing with three branches have been found based on the characteristic that the system composes a closed-loop of power flow. In consideration of the parts manufacturing errors,assembly errors,bearing stiffness and float,the power splitting rate of each star gear and the system were calculated by using the theory of equivalent mesh error. The effects of the errors,float and the bearing stiffness on power splitting were studied. The study provides a useful theoretical guideline for the design of star gearing.
Key words:    star gearing    deformation compatibility    power splitting    errors    float
