Based on the method of least squarest the datasheets and charts which were used in designing involute worm gearing were formulated , then designed the predigested computer aided design program 摘要运用最小二乘法对渐开线蜗杆传动设计计算的有关数表和线图进行了公式化处理,进而研制了这种传动的简化计算机辅助设计程序。
The involute cylinder worm gear is one of the ordinary cylinder worm gears . because of the specificity of the machine tool for this worm gear , its machine tool is not extensively developed in our country . the deep research on the involute worm gear is lack in our country 渐开线圆柱蜗杆是普通圆柱蜗杆中的其中一种,但由于加工这种蜗杆的机床的专用性太强,我国没有广泛发展这种机床,因此我国对渐开线蜗杆的研究还不够深入。
Tooth surface equations and contact line equations of the involute worm gearing are established according to its machining methodology . meshing characteristics in rigidity condition are studied . these characters include the inductive normal curvature along the contact line on the worm surface , the first and the second limit lines during the engage of the worm gear , and the influence of the intersect angle between the contact line the relative velocity of the worm and the gear on transmission performance 根据渐开线圆柱蜗杆传动的创成方法,建立了渐开线圆柱蜗杆和蜗轮的接触线方程式、齿面方程式,分析了渐开线圆柱蜗杆传动的刚性啮合特性,如蜗杆与蜗轮啮合时的诱导法曲率、一类界限曲线、二类界限曲线和蜗杆与蜗轮间相对速度方向和接触线方向的夹角对传动性能的影响; 2
Solid model of the involute worm gearing solid model with drive ratio 1 / 50 is built by using ideas - 5 . 0 , then the elastic contact analysis is proceeded on the basis of contact fem . the dynamic evolution image of the area of the contact zone , the load sharing among instantaneous meshing tooth pairs , the distribution of the contact force , and tooth stress are obtained . 3 通过渐开线圆柱蜗杆、蜗轮的齿面方程式,利用ideas - 5 . 0软件建立了传动比为1 / 50的渐开线圆柱蜗杆传动的实体几何模型,在此基础上应用接触有限元方法对该传动进行了弹性接触分析,包括接触区的形状、位置、载荷在瞬时啮合齿对的分配状况; 3
