摘　　要：根据齿轮传动的啮合原理和UG软件所提供的规律曲线,首先建立了形成困油区截面的封闭曲线及对应的“面”特征;接着运用“相交”的特征操作,创建出卸荷口截面的“面”特征;最后利用UG特征的面积属性,将提取出的这2类面积的变化值,传递给外啮合齿轮泵困油仿真的二次开发主程序,该过程是全自动的和参数化的,所得结果经实例验证是正确而可靠的。Based on the engagement principle of gear transmission and the function of rule curve supplied by UG software, the following problems were studied. Firstly, the variation mechanism of the closed curves that shaped the section outline of close cubage in an engagement periods was found and their corresponding face feature was created. Secondly, using the “and” feature operation to create the unloaded face feature. Thirdly, solid attribute and API development under UG software could acquire the two dynamic are...
