A systematic designing procedure to determine the gearing configuration arrangement of epicyclic gear transmissions for given speed ratios is presented. Vertices with symmetric dependency can be chosen from links by topological characteristics. Typical mode sets which are simplified from numerous modes can be established by substituting the symmetric dependency. By identifying the distribution of links, modes can be classified into different types of gain by sketching Kinematic Flow Diagram. In order to find the relations between each mode, the description of gain relations can be established by Rules which can substitute a gain by equations. According to the equations of relations, the sign relations of each mode are determined, and signs are substituted into the modes of typical mode sets. Admissible sign relations are chosen by the constraints of Rules, and inadmissible sign relations are deleted. Admissible configuration arrangements are established by choosing proper gain ranges, and the number of teeth of gear pairs is obtained by calculating teeth ratios.
