A study of the mechanics of the South-Pointing Chariot with the bevel gear type differential gear train was conducted. Firstly the pattern of this South-Pointing Chariot is replaced with the combined planetary gear system in which two simple planetary gear trains are connected. Secondly, through theoretical analysis, it is confirmed that power circulation occurs in the system. Thus the principle that fulfills the fundamental function of the South-Pointing Chariot is explained. Thirdly, it is confirmed that this analyzing method could be applied to the mechanical variable-speed drive which uses the combined planetary gear system.
