Elliptical Gears Parametric Design and Motion Simulation

摘要

Based on the design theory of non-circular gears, using Visual Basic 6.0 Programming language secondary developed SolidWorks software, a system of elliptical gears parametric design and motion simulation was developed. 3D parametric modeling and motion simulation of elliptical gears can be achieved by this system. The development process of system is introduced in detail, and an example which designed a transmission with two identical three rank elliptical gears was given to illustrate the system operation process in detail. Using elliptical gears pair ratio cyclical curves acquired, compared with theoretical transmission ratio can verify design whether meet the requirements. Complex design and calculation and difficult 3D modeling problems of elliptical gears are solved, and this system can also improve design precision, shorten the development cycle, and guarantee the quality of products.
