Abstract: Variable hyperbolic circular-arc-tooth-trace cylindrical gear with the features of small size, heavy load and high reliability and broad application prospects. The application of new type of transmission is to be extended. A modular design method for the mechanical system of the variable hyperbolic circular cylindrical gear special machine tools is developed. According to the functional requirements of this special machine tools, the comprehensive correlation matrix of system parts is obtained by taking the design concept as the main line and the function-principle-behavior-structure design process model as the principle of mapping and correlation analysis. On the basis of this, the system is divided into modules by the method of gap static and self-organizing map(SOM), and a variety of modules are divided. Finally, based on the technique for order preference by similarity to an ideal solution(TOPSIS) method, the modular partition solution is evaluated and the most suitable partition scheme is obtained. The rapid design and reconfiguration of the machine tools are realized by the research of modular partition method of the special machine tools for variable hyperbolic circular-arc-tooth-trace cylindrical gear.
