中文摘要：

为提高分插机构的设计效率,缩短设计开发周期,该文以偏心齿轮-非圆齿轮后插旋转式分插机构为基础,并以三维软件UG6.0为设计平台,利用可视化编程语言VB.NET定制用户界面,采用NX Open for.NET的UG二次开发技术,建立该分插机构的三维参数化设计系统。利用该系统,通过用户界面输入主要设计参数,即可快速生成偏心齿轮-非圆齿轮后插旋转式分插机构的零件（包括非圆齿轮）和装配三维模型,实现该分插机构的三维参数化设计。

英文摘要：

In order to improve the design efficiency and shorten development period of transplanting mechanism,3D parametric design system of the transplanting mechanism was built in this paper.Based on backward rotary transplanting mechanism with eccentric gears and non-circular gear,3D Software UG6.0 was chosen as design platform and UG secondary development technology of NX Open for.NET was adopted in the system.3D models of the parts and assembly of the transplanting mechanism,which includes 3D model of non-circular gear,can be easily created if users input the main design parameters of the transplanting mechanism by user interface of the system,and 3D parametric design of the transplanting mechanism can be realized.
