齿轮加工机床运动链误差频谱,包含低频和高频成份。每一误差成分在被加工零件上的遗传程度取决于工件一转中该种误差成分出现的相对频率。这就是为什么要尽量增加齿轮加工机床分度蜗轮齿数的原因。进一步增加分度蜗轮齿数,实际上不可能,因为这将减小模数和它的承载能力。目前出现了一种对机床和齿轮被加工齿面的误差周期进行误差配合的方法,即误差频率分割法。同时研究了此方法的发展前景。 Gear processing machine kinematic chain error spectrum, including low frequency and high frequency components. The degree of inheritance of each error component on the part being processed depends on the relative frequency at which the error component appears during one revolution of the workpiece. This is why you should try to increase the number of teeth of the gear processing machine indexing worm gear. It is virtually impossible to further increase the number of indexing worm gears as this will reduce the module and its load carrying capacity. At present, there is a method for error matching of the error cycle of the machined tooth surface of the machine tool and the gear, that is, the error frequency division method. At the same time, the development of this method is studied.
