[4A] 这张齿轮图纸的技术说明，你能看出哪里需要完善？

十年一梦

大家讨论一下有什么需要完善之处。

机械神话

希望看到这张图，机械图纸是图文并存的，不可分离。

这是你自己出图纸给鬼佬加工的？

, \& x7 }6 G. W- n: B8 ?这里的轴可能用axis比较合适，因为这根轴线不是实际存在的东西，同轴度本身就是个跳动值所以不用TIR。更应该直接标在图上。

老兄的东西每次看都有新发现。但是如果是一个齿轮的note，好像该有的东西全部没有：

这些都应该有上下公差或者标准值

没有图纸怎么分析啊？楼上有图纸了？

楼主你这应该是单个零件的技术要求吧？我觉得第三条动平衡应该去掉，单个零件的在这没什么用；第五条磨削余量没必要写在这个里面吧，毕竟是工艺要求；另外，你要求表面刀纹看不出，那就直接定个粗糙度Ra1.6以下，这个可去参考粗糙度标准样块；第十条未注同心度0.254你有和第三条校核没？单位是英制还是公制？有必要到小数点后三位？还有最后那条不太清楚你要干什么。
