8图样标注 8.1在齿轮工作图上,应标注齿轮的精度等级和侧隙种类。 8.2标注示例 8.2.1齿轮的三个公差组精度指标,采用相同的精度等级时,标注为:
例:齿轮的Ⅰ、Ⅱ、Ⅲ公差组精度等级同为7级,侧隙种类为g,标注为:
7 g GB 2363—90
8.2.2齿轮的三个公差组精度指标,采用不同的精度等级时,标注为:
例:齿轮的Ⅰ公差组精度等级为7级,Ⅱ公差组精度等级为7级,Ⅲ公差组精度等级为6级,侧隙种类为f标注为:
7—7—6 f GB2363—90
8.2.3当自行规定齿轮传动侧隙时,侧隙种类不标注。此时可在相应侧隙指标的公称尺寸上标注其上下下偏差。
例:齿轮的Ⅰ、Ⅱ、Ⅲ公差组精度等级同为7级,侧隙上偏差为-0.008、下偏差-0.050,标注为:
