英文摘要： According to the significant demands of precision transmission device for developing high-end equipment in the area of aerospace and national defense weapons, this project focus on the commonality and challenge issues of traditional precise gear transmission system on the manufacturing precision and service reliability under the extremely conditions, introducing the concept of integration of drive, transmission, sensor and control system to realize precision transmission. Based on the deflection compatibility design method, a rigidity-flexibility gear transmission system is proposed by introducing the rubber into traditional rigid gear as a flexible part, in order to realize high reliability and precision transmission. The dynamic friction model and the global coupled dynamical model are conducted to evaluate the regulating-controlling principles of force, displacement and movement performance in the rigidity-flexibility gear transmission system, in order to develop a theoretical basis for its intelligent control method. Therefore, this research will reveal an innovative thought and method for solving the commonality and challenge issues of high reliability and precision transmission device, which has scientific significance and practical values for advancing the technical level of the precision transmission device.
