《GB/T 4686-2008插齿机 精度检验》由TC22(全国金属切削机床标准化技术委员会)归口,TC22SC4(全国金属切削机床标准化技术委员会齿轮机床分会)执行,主管部门为中国机械工业联合会。
本标准代替GB/T4686―1984《插齿机 精度》。 本标准规定了插齿机几何精度、传动精度和工作精度检验的要求及方法。
本标准适用于最大工件直径为125mm~3150mm 的插齿机。 本标准与GB/T4686―1984相比主要变化如下:
―――增加了标准的前言;
―――增加了标准的“范围”(见本版第1章);
―――增加了“规范性引用文件”(见本版第2章);
―――增加了“术语和定义”(见本版第3章);
―――对G1项的简图、检验方法作了修改;
―――对G2项的允差值用计算公式进行确立;
―――增加了尾架顶尖对工作台回转轴线的几何精度要求(本版的G10.1、G10.2、G10.3);
―――取消了原标准的附则,将其附则的内容纳入本标准的相应章节中,并对其进行了适当修改;
―――调整了传动精度检验的允差值(本版的K1);
―――调整了工作精度检验的允差值(本版的P1)。


Scope

This standard specifies the requirements and methods for the inspection of geometric accuracy, transmission accuracy and working accuracy of gear shaping machines.
