摘　　要：针对采油单螺杆泵转子的数控加工,求解出了转子的法截面廓型坐标,提出了一种从转子法截面进行插补计算的新型加工方法,并通过与传统加工方法的理论计算对比、实际加工样品对比,得出了这种新型的加工方法具有加工精度高、加工速度快的优点。为采油单螺杆泵转子乃至定子模芯的实际加工提供一定的理论参考。In allusion to the numerical control machining of rotor in single-screw pumps for oil production,the coordinate of the rot normal section configuration was derived,a new machining method for run-in calculation from the normal section of rotor was proposed.Compared with the theoretical calculation of traditional machining and as well as compared with actual machining samples,the results show that the new method has the advantages of high accuracy and rapid machining.It provides theoretical reference for machining the rotors and cores of single-screw pumps.
