摘　　要：根据齿轮误差理论,对滚齿加工的圆齿轮大、小周期误差进行研究。研究表明,对于滚齿加工来说几何偏心对左、右齿面产生的啮合线误差等于该齿面上的径向与切向之和,运动偏心对左右齿面产生了一个大小相等且方向相反的误差,滚刀轴向跳动对工件的齿形精度的影响比径向跳动的影响大。According to the theory of gear errors, the large and minor periodic errors in the non-circular gears are researched in this paper. The study shows that for gear hobbing, the meshing line error of the left or the right tooth surface which is gener-ated by the geometrical offset is equal to its sum in the left or the right tooth surface on the radial and tangent directions. An error which is equal and opposite in direction is generated when the motion eccentricity affects the left and the right tooth sur-faces, and the axial shifting of hobbing cutter has much impact on the accuracy of tooth shape than the radial pulsation.
