摘　　要：为了提高齿轮建模的准确性和效率,解决齿数多于41个齿时的齿廓自动生成问题,文章对渐开线齿轮全齿廓进行精确计算,编制软件自动生成齿轮全齿廓,并在CATIA软件中建立参数化的齿轮模型。最后给出普通建模方法与文中所提方法的模型的齿轮弯曲强度对比计算分析,证明了文中所述方法的有效性。另外,文中将编程软件和三维软件有机结合,提供了一种三维软件二次开发之外的零件建模的新思路。In order to improve the accuracy of gear modeling and resolve the question of automatically generating the whole tooth profile when the numbers of teeth exceed 41, the acticle gives a way of calculating the whole tooth profile of involute gear, supplies a software to automatically generate all datas of gear entire profile, and creates a parameterized model of the gear in CATIA. Finally,the comparison analysis of gear bending strength between the ways of the general modeling approach and the article＇ s is supplied,and the effectiveness of the method is proved.In addition, through organicly combining the programming software and three-dimensional software, new ideas for modeling parts are provided outside of the secondary development on three-dimensional software.
