目的 针对展成磨齿过程中，螺旋线修形引起的左右齿面螺旋线倾斜偏差问题。方法 提出一种基于虚拟Y轴运动的斜齿轮螺旋线偏差补偿策略。建立蜗杆砂轮磨齿数学模型，通过求解啮合方程得到了左右齿面瞬时接触迹线。构建通用高阶多项式螺旋线修形曲线，分析了砂轮与左右齿面接触位置不同导致的齿面偏差量，通过Y轴与虚拟Y轴的叠加运动进行齿面偏差补偿，并开发了相应的数控补偿程序，将补偿运动与磨齿机床的数控联动关系进行集成。结果 通过磨齿加工试验进行了验证。结果表明：补偿后的左右齿面螺旋线非对称偏差量较补偿前降低了69%。结论 该补偿策略可有效降低螺旋线修形引起的螺旋线倾斜偏差。
Abstract：Objectives For the problem of left and right flank helix slope deviation induced by helix modification during generating gear grinding. Methods A helical gear helix deviation compensation strategy based on virtual Y-axis motion is proposed. Firstly, a mathematical model for worm wheel grinding is established, and the instantaneous contact lines of the left and right tooth flanks are obtained by solving the meshing equation. A universal high-order polynomial helix modification curve is constructed, and the tooth surface deviation caused by the different contact positions between the grinding wheel and the left and right tooth flanks is analyzed. Tooth surface deviation compensation is achieved through the superimposed motion of the Y-axis and the virtual Y-axis, and a corresponding CNC compensation program is developed to integrate the compensation motion with the CNC linkage relationship of the grinding machine. Results Verification through grinding experiments shows that the asymmetric helix deviation of the left and right tooth flanks after compensation is reduced by 69% compared to that before compensation. Conclusions The proposed compensation strategy can effectively reduce the helix slope deviation caused by helix modification.
