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。
Honing gears with excellent tooth surface texture, transmission noise is small, residual compressive stress, long life and other advantages. In the honing process, the relative speed of the honing wheel and the machined tooth surface determines the honing throughput and texture. Starting from the theoretical model of involute helicoid, the formula of relative velocity at the contact point between the worm-shaped honing wheel and the machined gear is deduced. The change trend of relative speed at each contact point was analyzed to find out the worm-shaped honing wheel parameters related to the speed change. According to the adjustment of honing wheel number and its subdivision circle diameter, the influence on the relative speed is analyzed, and the worm honing wheel is optimized.
