摘要Pro/ENGIEER 提供了强大的三维几何造型功能，使它能够创建各种复杂的几何零件模型,但有时这些功能并不能满足我们的要求。例如标准零件系列，它们的结构都是相同的，区别只在与尺寸，如果标准零件系列通过三维建模的方式来实现，那么工作量将是非常巨大的。最有效的方法使利用标准零件的相似性，发挥Pro/ENGEER参数化建模的特长，使用二次开发工具，如族表工具、用户定义特征（UDF）、Pro/Program、J-link、Pro/Toolkit等来实现。48807

本课题针对直齿圆柱齿轮和斜齿圆柱齿轮，提出基于Pro/E平台进行二次开发的一种可行方案。并且成功开发设计出能满足用户要求的齿轮模型库。

本文首先简单介绍了与本课题相关的Pro/E二次开发功能，包括自定义菜单的设置、对话框的制作、Pro/TOOLKIT应用程序的执行。其次根据本课题的要求，分析了齿轮二次开发的整体设计思路。然后以直齿圆柱齿轮为例，较详细地说明了利用Pro/TOOLKIT及Microsoft Visual Studio 2005在Pro/E二次开发中的应用，最后对开发的三维建模程序进行测试。结果表明：基于PRO/E二次开发的参数化设计操作简便，建模较为迅速，一定程度上提升了这类通用件在Pro/E平台上的设计效率。

Abstract Pro/ENGIEER offers a powerful three geometric modeling function, so that it can create a variety of complex geometric model parts, but sometimes these functions do not meet our requirements. For example, standard parts series, their structure is the same, the only difference is size, if the standard parts series achieve by3D modeling method, so the workload is very large. The most effective way is making use of the similarity of standard parts, playing Pro/ENGEER parametric modeling expertise, the use of two development tool, such as a family table tool, user defined feature ( UDF ), Pro/Program, J-link, Pro/Toolkit etc.

This article introduces a feasible method of secondary development based on Pro/E against some kinds of gears. And the gear parts library is successfully designed meet to the user requirements.

Firstly, this article simply introduces the secondary development functions of Pro/E referring to this task which includes the creation of menu, the creation of the dialogue, the Pro/TOOLKIT procedure execution. Then the precept to the overall design way of gear secondary development is analyzed. With an example of a round cross-section helical compression gear in detail, it particularly describes the application of Pro/TOOLKIT and Microsoft Visual Studio 2005 in the secondary development base on Pro/E, and test examples. At last, the test of all process of three-dimension-part-model driven by database is performed indicates that he seconded development of parametric design Based on the PRO/E is simple ,relatively rapid modeling, and the mold can be set up quickly. The efficiency for the design of interchangeable part based on Pro/E can be increased.
