A hybrid gear aligning mechanism was designed to solve the problem of aligning rotation of spatial hexagonal structure using the gear drive configuration design method. The functional structure of this mechanism was analyzed to realize the spherical rotation of spatial polygon structure. The multi-body dynamics model of gear aligning mechanism was established by dynamical simulation software ADAMS. The transmission process of hybrid gear aligning mechanism was simulated to obtain the stress curves of movement characteristic. The simulation results showed that the spherical bodies output met the needs of rotational movement of spatial hexagonal structure. A prototype of gear aligning mechanism was developed. It was able to guarantee the spherical rotation accuracy of spatial polygon structure, and verified the design rationality of the gear aligning mechanism.
