摘　　要：珩齿后齿轮有着齿面纹理优良、传动噪声较小、残余压应力高、使用寿命长等优点。在珩齿加工中,珩磨轮与被加工齿面的相对速度决定了珩磨加工量和纹理。从渐开螺旋面的理论模型入手,推导在蜗杆状珩磨轮和被加工齿轮啮合时接触点上的相对速度公式。并分析各接触点处的相对速度变化趋势,找出与速度变化相关的蜗杆状珩磨轮参数。根据珩磨轮头数和其分度圆直径的调整,分析其对相对速度产生的影响,对蜗杆状珩磨轮进行优化设计。The gear after honing has many advantages,such as good tooth surface texture,smaller noise in transmission,high residual compressive stress and long lifetime etc. In the gear honing process,the relative speed which is between honing wheel and processing tooth surface determines honing process capacity and tooth texture. From the theory model of involute helicoid,the relative velocity formula at contact points when worm honing wheel and work piece are engaging is derived. By analyzing the change trend of relative velocity at contact points,the parameters of worm honing wheel which related to the change of velocity are found. According to adjustment of the parameters of number of thread and reference circle,the influence on the relative velocity is analyzed,then optimizing design of worm honing wheel is carried out.
