【摘要】：本文建立了双圆环面二次包络环面蜗杆副(双圆环面二包副)传动啮合分析的数学模型;结合啮合原理、数值运算,分别得出了第一次和第二次啮合过程中的啮合函数、蜗杆螺旋面和蜗轮齿面方程、以及包括啮合界限函数在内的一些列啮合特性参数。通过算例,基本搞清楚了双圆环面二次包络环面蜗杆的啮合特性,以及设计参数对啮合质量的影响。结果显示,双圆环面二次包络环面蜗杆传动具备一系列优良的啮合特性,例如,蜗轮齿面上存在宽阔的接触区,较长的蜗杆双线工作长度,尤其是双圆环面二次包络环面蜗杆能够有效地避免根切和边齿顶变尖。另外,平面产形砂轮、锥面产形砂轮、双锥面产形砂轮及球面产形砂轮,都可看成是双圆环面产形砂轮的特例。而且双圆环面产形砂轮的可调参数较多,这为进一步改善双圆环面二次包络环面蜗杆的根切特性,提供了广阔的空间。
[Abstract]:In this paper, the mathematical model of meshing analysis of double ring surface double enveloping worm gearing is established, and the meshing functions in the first and second meshing processes are obtained by combining the meshing principle and numerical calculation, respectively.The equations of worm helical surface and worm gear tooth surface, as well as some meshing characteristic parameters including meshing boundary function.The meshing characteristics of double ring double enveloping worm and the influence of design parameters on the meshing quality are studied by numerical examples.The results show that the double ring double enveloping worm drive has a series of excellent meshing characteristics. For example, there is a wide contact area on the tooth surface of the worm gear, and a long double line working length of the worm.Especially the double ring double enveloping worm can effectively avoid root cutting and edge tooth tip sharpening.In addition, the plane shaped grinding wheel, the cone shape producing wheel, the double cone shape producing wheel and the spherical producing shape grinding wheel can all be regarded as the special cases of the double ring surface producing grinding wheel.Moreover, there are many adjustable parameters of the grinding wheel with double ring surface, which provides a wide space for further improvement of the root tangent characteristics of the double ring surface double enveloping toroidal worm.
