阐述了以滚齿机为代表的按范成法工作的齿轮机床分度链运动误差与切齿周节误差的关系;从滚齿机分度链运动误差与被加工齿数的函数式,绘成滚齿机运动精度状况特征图,能直观地反映在机床任何切齿齿数情况下的运动误差状况;比较了滚齿机在空载和切齿两种状态下运动误差及其影响因素;提出了根据机床运动误差曲线求切齿周节误差的图解方法;指出切齿周节误差不能反映分度链中刀具轴至差动轴的运动误差;最后简述了在我国贯彻执行ISO-6545标准K1项运动精度检测的必要性和现实性。
The relationship between the motion error of gear machine indexing chain and the pitch error of cutting gear, which is represented by gear hobbing machine, according to the normalized method is expounded. The motion accuracy of gear hobbing machine is plotted from the function of motion error and number of teeth to be machined, Which can directly reflect the motion error condition of any gear teeth in the machine tool. The error of the gear hobbing machine under no-load and gear-cutting conditions and its influencing factors are compared. A graphical method of calculating the error of the pitch circle of the gear according to the motion error curve of the machine tool It is pointed out that the error of the cutting edge pitch can not reflect the movement error between the tool axis and the differential axis in the indexing chain. Finally, the necessity and reality of carrying out the motion accuracy detection of K1 in ISO-6545 standard are briefly described.
