For planetary gears in factory-automation use, compact size, high torque capacity, high precision rotation, and small backlash become required conditions. These requirements bring difficulties to reasonable estimations of influences of geometrical errors to important characteristics; load distribution, transmission error, and sun gear radial displacement. This is considered to be the unsolved subject in the accuracy precision design in this field. This paper deals with static modeling, simulations with a composed model and relating experiments to clarify the subject mentioned above. The model is formulated by regarding eccentricities of axes, cumulative pitch errors of gears, positional deviations of planet gears' axes, stiffness in gearing contacts and loading torque as parameterS. The simulations, under practical conditions, are carried out with regard to load distribution, transmission error, and sun gear radial displacement. Good agreements are obtained between the experiments and the simulated data.
