摘　　要：从接触线和啮合界限线的角度对二次包络TI蜗杆传动进行了接触性能分析。分析表明,只有当蜗轮齿面上的啮合界限线为一条或两条且这两条线不重合时,才能在二次包络TI蜗杆传动副的蜗轮齿面上得到二次接触线;在加工允许的范围内,螺旋角取较大的数值,能够较好地改善啮合性能,从而发挥二次包络TI蜗杆传动的优势。研究对合理选择设计参数具有指导意义。From the point of view of the contact line and the meshing limit line, the contact performance of double enveloping TI (Torioidal Involute) worm gearing is analysed. The results show that only when there is one meshing limit line on the worm tooth flank or two lines which are not coincide with each other can the second contact line be seen on the worm tooth flank of double enveloping TI worm gearing. Within the range of machining, if the helix angle adopts a bigger value, it may improve the meshing performance and develop the advantages of double enveloping TI worm gearing. The studies are practicably instructive for selecting reasonable design parameters.
