Application of Symmetrical Equations in Parametric Design of Involute Gear

Article Preview

Abstract:

Parametric design based on feature is the main method in parametric modeling of involute gear. In this paper, symmetric equations of the involute and the fillet curve are established according to the coordinates of points symmetrical about a straight line. And the tooth profile or alveolar profile of involute gear is generated accurately through controlling parameter of equations quantitatively. The problem of generating tooth profile accurately can be solved. Then the correctness of gear’s parametric design is ensured. The accuracy and efficiency of the gear’s engineering design are all improved.
