[Abstract]:Planetary gear transmission has been widely used because of its compact structure, strong bearing capacity, large transmission ratio, stable movement and high transmission efficiency. Kinematics analysis and the calculation of transmission efficiency are important contents in the design and analysis of planetary gear transmission mechanism. On the basis of deeply studying the kinematics analysis of planetary gear transmission and the calculation of transmission efficiency, this paper uses the method of dividing the basic circuit to systematize the configuration of planetary gear mechanism. Thus the topological relation of planetary gear mechanism is accurately expressed. Visual C 6.0 is selected as the development tool, according to the general process of software development, the software functions to be realized are determined. According to the design principle of the program interface and the actual situation of the project, the development of the software program interface is completed, and the design process of the kinematics analysis software for the planetary gear mechanism is realized. The analytic geometric kinematic equation expression of planetary gear mechanism kinematics is simplified by means of logical expression, and it is applied to the actual programming of software. Finally, the kinematics analysis software of planetary gear train and differential gear train that can operate independently is generated, and the function of numerical calculation module and loop relation diagram analysis module is used. The single degree of freedom planetary gear mechanism and the double degree of freedom differential planetary gear mechanism are calculated and analyzed. The kinematics values are obtained and the circuit diagram is drawn and analyzed, and the numerical results are compared with the theoretical formulas. The calculated results of the analytic geometry method are compared with each other, and the results are completely consistent, thus verifying the accuracy and reliability of the analytic geometry method and the software in solving the kinematics analysis of the planetary gear mechanism. The kinematics analysis of planetary gear mechanism is realized programmatically. In addition, the calculation of the efficiency of planetary gear transmission is also more complicated, which can be simplified by software. The software is applied to the design and analysis stage of three kinds of NGW,WW,NGWN mechanisms through examples. The kinematics analysis is carried out, and the numerical results are obtained. The evolution trend of the mechanism is investigated by using the function of software loop diagram analysis. And finally determine the configuration; At the same time, the transmission efficiency of the mechanism is calculated by combining the results with the analytic geometry method. The results show that the software can simplify the design and analysis process of the planetary gear mechanism. Finally, the kinematics analysis results of common planetary gear mechanism are discussed, which is convenient for designers to grasp the characteristics of different configurations as a whole. A practical feature.
