摘　　要：基于单滚子包络环面蜗杆传动,修改得到了一种新型蜗杆传动——并列倾斜式双滚子包络环面蜗杆传动。根据单滚子包络蜗杆传动原理以及空间齿轮啮合理论,构建了并列倾斜式双滚子包络环面蜗杆传动的基础数学模型;以建立的数学模型为基础,分析推导了该新型蜗杆传动的基本特性参数——诱导法曲率、润滑角、自转角以及啮合方程、齿面方程等;根据得到的基本特性参数,分析了该新型蜗杆传动的啮合性能。结果表明,该新型蜗杆传动具有良好的啮合性能。Based on the modification of single roller enveloping hourglass worm drive,a new type of worm drive,parallel inclined double roller enveloping hourglass worm drive is proposed.According to the principle of single roller enveloping worm drive and spatial meshing theory,the basic mathematical model of parallel in⁃clined double roller enveloping hourglass worm drive is constructed.Based on the established mathematical model,the basic characteristic parameters of the new type worm drive,such as induced normal curvature,lu⁃brication angle,self-rotation angle,meshing equation and tooth surface equation are analyzed and deduced.According to the obtained basic characteristic parameters,the meshing performance of the new worm drive is analyzed.The analysis results show that this new type of worm drive has good meshing performance.
