摘　　要：变齿厚平面蜗轮传动的全称为“侧隙可调式变齿厚平面蜗轮包络环面蜗杆传动”,它是介于传统“运动传动”和“动力传动”之间的一种新型精密动力传动.利用啮合原理的知识,笔者推导出变齿厚平面蜗轮传动副的齿面方程.在此基础上,又用I-DEAS8.0软件建立了具有精确齿廓形状的变齿厚平面蜗轮传动副的实体模型,并对变齿厚平面蜗轮传动副进行了有限元分析,求解出了该传动副的主应力分布、齿间载荷分配等情况,为这种蜗杆传动的强度和性能分析提供了一定的依据.The full name of variable tooth thickness plane worm gear transmission is. Backlash adjustable plane worm gear with variable tooth thickness enveloping worm transmission, which is a new kind of accurate power transmission that is intervenient between traditional motion transmission and power transmission. Tooth surface equations of the variable tooth thickness plane worm gear transmission are deduced based on the theory of engagement. Basing on the result, the authors create a finite analysis model of backlash adjustable variable tooth thickness plane enveloping worm with perfect tooth shape by using I-DEAS software, and then has done finite element analysis of backlash adjustable variable tooth thickness plane enveloping worm transmission. Finally, the author drew a conclusion about distribution of principal stress and load distribution between teeth, which offer some references for strength and performance analysis of worm transmission.
