【摘要】 对用蜗杆砂轮磨齿机加工高精度渐开线圆柱齿轮齿廓时节点附近出现凹下的齿形误差现象应用网格法进行了分析研究,得到了避免由于与刀具啮合齿数的变化所引起的齿形误差的齿轮变位系数选择方法,并通过实验进行了验证。更多还原

【Abstract】 By means of grid method,this paper analyzes and studies the gear tooth shape concave error appeared near the pitch point during the machining process of high precision cylindrical involute gears with the worm grinding machine.The selecting method for the gear modification factors to avoid tooth shape error caused by variation of the number of engaged teeth of cutting tools is obtained.The result has been verified by experiment.更多还原
