Analysis of Static Load Sharing in Planetary Gearing

A calculative model for single stage planetary gear (type 2K-H) is presented and the analysis of the mechanism of load balance is given. In consideration of the parts′ manufacturing error and assembly error, the load sharing coefficient of each planetary gear is calculated by using the theory of equivalent mesh error and equivalent mesh stiffness, then the relationship between error and load sharing is analyzed. This analysis is helpful for the design of planetary gearing.
