摘　　要：在无侧隙双滚子包络环面蜗杆传动和滚锥包络环面蜗杆传动研究基础上,提出倾斜式双滚子包络环面蜗杆传动,分析了该传动的工作原理,建立了蜗轮、蜗杆的动静坐标系及滚子的活动坐标系,并进行了相关的坐标变换,依据空间啮合原理推导出了齿面接触线及齿面螺旋线所表示的蜗杆齿面方程,最后运用MATLAB软件对蜗杆进行了数值仿真。该蜗杆的建模分析为倾斜式双滚子包络环面蜗杆传动进一步的研究提供了理论参考。Non-parallel double-roller enveloping hourglass worm gearing was proposed based on the research of non-backlash double-roller enveloping hourglass worm gearing and rolling cone enveloping hourglass worm gearing.By analyzing the working theory of gearing,the dynamic and static coordinate system based on worm gear pair and the moving coordinate system based on the roller were established.The relevant coordinate transformations were deduced,the contacting line and spiral line equations of tooth surface were attained according to space engagement theory.The simulation was conducted using software MATLAB.The study provided an important theoretical basis for the next research of non-parallel double-roller enveloping hourglass worm gearing.
