A high order elliptic gear parametric modeling system based on MATLAB and SolidWorks

The design and modeling of high order elliptical gears have been studied.According to the gear fitting transmission characteristics,a mathematical model of the section curve was derived,and a mathematical model of the gear tooth profile was deduced according to the machining principle.Using MATLAB to simulate the pitch curve and gear tooth profile,the simulation results were used for program parameter calibration to ensure that the gear design parameters meet the meshing requirements.Using component object model (COM) technology for the subsequent development of SolidWorks,the program can automatically draw the gear three-dimensional model according to the simulation results.The design of an interactive interface through GUI enables the program to drive SolidWorks and MATLAB independently.When employed in practical engineering problems,for example,calculation and drawing of the fitting of a high order elliptic gear three-dimensional model,the new program can greatly save time,and improve the efficiency of the mechanical design of high order elliptic gear systems.
