本文详细的介绍了计算机辅助设计在设计齿轮传动中的应用。随着现代工业的发展，生产的提高，工业生产对齿轮的要求也越来越高。所以齿轮传动的设计就显得尤为重要了。而从事机械齿轮设计的人员常常因为烦琐的计算公式和齿轮各种参数选择而头痛不已，针对这种情况，本文采用了以VB为开发平台的齿轮传动设计系统，对齿轮传动进行设计。 本文先对计算机辅助设计的定义及应用作了简单介绍，突出了其应用优点，而后简单概括了一下本设计所需要的Access数据库，接着，比较全面地介绍了齿轮设计的定义，设计齿轮应满足的基本要求，设计的基本过程，以及设计齿轮所要考虑的各项参数，如在不同工作环境下所要考虑的齿轮材料，热处理的方法，精度选择等等因素，然后特别的比较详细的介绍了最常见常用的圆柱齿轮设计过程。在接下来，简单的介绍了一下齿轮的结构设计。由于VB的编程需要数据库的支持，本设计所采用的是Access数据库。本文紧接着便介绍了Access数据库的基本知识及如何建立本设计所需要的数据库。 在文章的最后，介绍了VB的基本知识，然后详细的介绍了本软件编制的过程,如窗体的制作，数据库的调用等等。经过调试，可以进行简单的齿轮设计计算。关键词（本论文范文的主要论点）：VB，ACCESS数据库，齿轮传动 AbstractThis paper introduced the computer aided design, CAD detailedly in design wheel gear spread move of application.Along with the modern industrial development, the exaltation of the production, the industry produces is too more and more high to the request of the wheel gear.So the wheel gear spread the dynamic design and then seem to be particularly for importance.But usually be engaged in the personnel of the machine wheel gear design the headache is without stop because the trivial calculation formula chooses with wheel gear every kind of parameter, aiming at this kind of circumstance, this literary grace used with VB for wheel gear that develop the terrace to spread to move to design the system, spreading to move the proceeding design to the wheel gear. This text made the simple introduction to definition and applications of the computer aided design, CAD first, outstanding its applied advantage, generalized and then and in brief once the data base, DB of Access that this need when designing, immediately after, compared to introduce the definition of the wheel gear design completely, design the wheel gear at the request of satisfy basic, the basic process that design, and design various parameters of the consideration that wheel gear want, such as wheel gear in different the consideration wanted in work environment material, hot processed of method, accuracy choice etc. factor, then specially of detailed introduction the most familiar and in common use cylinder wheel gear design process. At connect the introduction that come down, in brief once the construction design of the wheel gear. Because of VB plait distance demand data base, DB support, this design what adopt is t Access. This paper was close behind to introduce the data base, DB of Access basic knowledge then and how to establish the data base, DB that this need when designing. In the article finally, introduced the VB basic knowledge, then introduced the process of this software establishment detailedly, such as the creation of the window, the data base, DB adjusts to use the etc..Passes by to adjust to try, can proceed the simple wheel gear design calculation.Key words:VB, the data of ACCESS, gear-driven
