In this study, the establishment of optimal objective function of wheel edges gear reducer mainly aims at reducing the structure＇s volume. According to the structural characteristics of wheel edges gear reducer, the design variables and constraint conditions of the model were determined and an optimal mathematical model of the wheel edges gear reducer was also set up. The structural optimization was carried out by GA （genetic algorithm） based on MATLAB software. Taking a type of wheel edges gear reducer as an example, the results have shown that this method can obtain a better optimal structural scheme, and could effectively reduce the wheel edges gear reducer＇ s dimensions. The feasibility and validity of this method have been proved and it has important theoretical basis.
