摘要
针对目前传统的包络法加工平面二次包络环面蜗杆副在精度上的缺陷,探讨了其数控加工工艺。根据制定的加工工艺,提出通过控制步进电机的转角并将其应用到数控系统中的螺纹指令的原理来完成螺旋面加工,对原有的CA6140车床在结构上进行改造,通过对加工部件的选择、编程参数的计算、CNC程序的编制等来实现平面二次包络环面蜗杆副的数控加工。
Planar double-enveloping worm pair is an excellent transmission type. The shortages of traditional processing method were insurmountable and the CNC machining technique was researched. Then the common lathe-CA6140 was reshaped, the components were selected, the parameters were calculated and the NC Program of the planar double-enveloping worm was compiled, on base of these methods the CNC manufacturing of planar double-enveloping worm pair was complicated.
