Static Load Sharing in Power-Split Planetary Gear Trains

Abstract:

Based on analyzing the mechanism of load sharing of power-split planetary gear trains, equivalent mesh errors are defined and introduced in this paper to take the deformations and manufacturing and assembling errors into account. The static equilibrium equation of planetary gear trains is established. Then the load sharing coefficients of a power-split planetary gear system are calculated. The results indicate that the load sharing of power input stage is worse than that of the power output stage in the power-split planetary gear system.
