In this paper, the kinematic characteristic model of parallel shaft gear train is established, the comprehensive solution method of parallel shaft gear train motion scheme is discussed, and the software for solving parallel shaft gear train motion scheme is developed preliminarily. Firstly, the characteristic model of basic unit motion of parallel shaft gear train is established. Taking the basic unit as the basic research object for solving the motion scheme of complex gear train, the motion function features of the basic unit are extracted, and the basic unit motion feature model is established to describe the transformation of the basic unit motion feature state. The basic unit motion feature vector and motion characteristic equation are established, and the motion feature matrix is extracted, and a relatively complete basic unit library is preliminarily established by summarizing the common basic units. Secondly, the kinematic characteristic model of parallel shaft gear train is established. Analyzing the combination form of basic unit, generalizing the common combination form of basic unit, that is, series type, feedback type, parallel type and compound type, etc. The process of determining the combination of elements is the process of introducing constraints. The component connection constraint equation is established to describe the combination process of the basic unit. According to the combination form of the basic unit, the characteristic model of the combined motion of the unit is established, and the composite element is defined. Together with the basic unit, it is used as the unit mechanism for the analysis and synthesis of the gear train motion scheme, and the motion characteristic model of the composite unit is established, and the composite unit library is established. The basic unit library and the composite unit library are called the unit library. Then, the method of solving the motion scheme of parallel shaft gear train is discussed preliminarily. The transmission ratio range of the unit in the unit library is deduced, and the relationship between the transmission ratio of the unit and the element of the motion characteristic matrix is obtained, and the decomposition rules of the motion characteristic matrix are established according to the combination form of the unit. It provides the possibility for the realization of computer-aided motion scheme design, establishes the steps of motion scheme design, analyzes the combination constraints of units and establishes the synthesis process. Finally, the software for solving the motion scheme of parallel shaft gear train is developed preliminarily. Analyzing the function requirement, establishing the system structure of the motion scheme solution software, developing the motion scheme solution software of gear train, and validating the feasibility and correctness of the motion scheme solving method of the paper through the design example.
