Classification and Synthesis of Epicyclic Gear Trains

Topological graph was applied to analyze and synthesize epicyclic gear trains(EGTs) and three topological graphs of basic structure of gear transmission and four fundamental units of EGTs were established firstly.Then the structure of topological units was defined based on stratification.Topological characteristics,combinational regularity and evolutionary mode of different EGTs were described by topological unit graphs.And the principles and specific methods of criterion isomorphic topological diagram were presented with an example.Lastly the formula of combination quantity of complicated EGTs was created based on four basic gear train units.Composition axiom,classification and synthesis methods were also put forward according to the loop features in topological graphs.
