Development of 3-D Parameterized Design System for Involute Gear Parts
Taking the three-dimensional CAD software Solidworks as developing platform and with the help of its powerful OLE technical support offered, the mathematical model of involute curved surface of bevel gear is established and the 3-D parameterized design and analyzing system for involute gear parts is developed in the paper. By inputting necessary variables on the interface of the gear design system an accurate 3-D parameterized geometric entity of involute gear can be automatically created. In the design system a kind of method called template technique is developed to realize the conversion of a gear part from 3-D geometric entity to corresponding 2-D standard engineering drawing and the marking of necessary design technical requests and parameters on the engineering drawing automatically, which offsets the lack that current three-dimensional CAD software can not automatically create standard two-dimensional CAD engineering drawing. Also the gear strength checkout program module is developed which is helpful to greatly improve design efficiency of involute gear parts.
