Parametric gear wheel applications in computer aided design

In this study, a software has been developed to parametrically draw and model the gear wheels and gear wheel pairs in a CAD (Computer Aided Design) environment. In the software development, a hybrid programming structure using Visual BASIC and AutoLISP programming languages is used for the proposed software. The programming languages are easy and commonly used. In the software system, gear wheels or gear wheel pairs are sized by inputting parameters such as modules, transmission ratios, teeth numbers, etc. and then they are automatically drawn and modeled in CAD environment. This study presents an auxiliary program which is rapid and functional to the designer for drawing and modeling of gear wheels.
