摘　　要：建立了锥面二次包络环面蜗杆传动啮合分析的数学模型，引入了生产中便于实现的各种修形参数，总结出确定修形类型的规则，编制了啮合分析软件包，提出求解齿面实际接触区域的方法，并根据相位分析法研究了各种类型传动的齿面结构，分析了蝇杆边齿变尖和根切的影响因素。对标准传动进行了全面的啮合分析，首次对△b修形传动进行了研究，并对Ⅰ型和Ⅱ型修形传动进行了啮合分析。理论计算的齿面接触区域与实验获得的齿面接触印痕相符。A mathematical model about gear meshing analysis of cone-generated double enveloping worm gearing is built and various modification parameters available in manufacturing are introduced. The rule identifying modification type is advanced and worm gear pairs are classified as standard worm, △b modification worm and comprehensive modification worm (including type Ⅰ and type Ⅱ ). A computer software package is developed successfully. The tooth contact pattern is calculated and a method determining structure of worm gear tooth flank on the basis of phase analysis is proposed for all worm types. The factors which affect worm tooth top thickness and tooth undercut are also analyzed. Gear meshing analysis on standard worm and comprehensive modification worm are completed. △b modification worm and its meshing feature are studied for the first tirne. Theoretical tooth contact pattern is well con formed with experimental tooth bearing.
