基于对球面蜗杆副形成原理的分析和研究,给出了为满足加工球面蜗杆齿形要求的滚齿机的改进方法,提出了为保证蜗杆各项精度所要采取安装、找正、切齿加工等有效的工艺措施。通过实际切齿的验证,证明了在没有专用的加工设备、单件小批量时该方法可行有效。 Based on the analysis and research on the forming principle of the spherical worm pair, an improved method of hobbing machine to meet the requirement of the profile of the spherical worm is presented. The effective techniques such as installation, alignment and cutting are put forward to ensure the accuracy of the worm. Measures. The actual cutting teeth proved that the method is feasible and effective in the absence of special processing equipment and single small lot.
