摘　　要：小模数精密锥面包络圆柱蜗杆(ZK蜗杆)是一种非线性螺旋曲面蜗杆,传统的车削加工方法难以保证其加工精度,现多采用由锥形铣刀(或砂轮)包络而成的铣削加工方式。针对ZK蜗杆的特点,在分析影响ZK蜗杆传动性能的误差基础上,对铣削加工过程中如何控制齿形、齿厚、螺旋线误差和齿面粗糙度进行了阐述。结合生产实际经验,提出了行之有效的精度控制方法和检测措施,对提高ZK蜗杆以及同类型的蜗杆的设计水平和制造精度具有现实的指导意义。Fine-pitch precision cylindrical worm of cone envelope （ZK worm） is a nonlinear spiral surface worm. The traditional method of machining technology is lathe. It is difficult to guarantee the precisions of ZK worm. At present,the milling method is increasingly adopted. Aiming at the characters of ZK worm,the errors of affecting ZK worm drive performance are discussed in this paper. Focusing on how to control the tooth shape,tooth thickness,spiral line errors and worm surface roughness are described in milling progress. Combined with practical experience in production,effective control methods and measures of checking the accuracy are put forward. It has a practical significance for guiding for the production of the same type of worm.
