Application of CAD Programs for a Gearing Geometric Model

Abstract

CAD programs are used in engineering environment on a daily basis, because of their wide use in designing, machining or evaluating process. This fact boosted the development and impact range of CAD software possibilities, but in the field of gears, there may be some shortcomings. These shortcomings are presented in a lack of gear generating tools or addons, and also in a possibilities these tools and addons provide. For uncommon geometries of gears, user may need to use other methods. Some of them are explained in this article. The advantages of explained methods are that they can be used for almost any gear wheel, or the modification of existing gear is quicker.
