Abstract: Based on the transmission characteristics of non-circular gear, the tooth location on the non-circular pitch curve and the formula of gears transmission relationship are determined. A design method of three-dimensional modeling for non-circular gear is given. Using Visual Basic language to carries on re-development of Solid edge, the parametric design and motion simulation of the ellipse gear pairs are achieved under three-dimensional environment. The gear teeth’s meshing situation can be observed visually. Systematic working effect is fine. A three-dimensional design method of non-circular gear transmission is provided.

Key words: computer application, motion simulation, parameterized design, ellipse gear
