A new design method of the combined planetary gears capable of achieving high-reduction ratio while relaxing the contraint for correct gear teeth assembly was proposed and examined. In case non-isogonic allocation of planetary gears was allowed, assembly constraint would be relaxed and the freedom in planetary gear design was significantly expanded. This expansion enables to configure high-reduction combined planetary gears that was not feasible in conventional design allowing only isogonic allocation. However, the non-isogonic structure would not result in dynamic unbalance that causes noise and vibration through proper mechanical design.
