[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？
1. MATERIAL: ALLOY STEEL 9310H-NORMALIZED & TEMPERED TP HRc 32-40.(AIR CRAFT QUALITY FORGING).
材质应写入材质栏，这里只要写热处理方式和最终硬度
2. CENTERS ARE MANDATORY ON BOTH ENDS OF SHAFT. ALL DIAMETERS MUST BE MACHINED USING THESE CENTERS AND -A- & -B- DIAMETERS MUST BE CONCENTRIC TO THESE CENTERS WITHIN 0.005 TIR.
! T, D9 S: ?% g" K. O' S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。
3.DYNAMICALLY BALANCE WITHING 0.26 OZ-IN AT PLANES INDICATED INSTALL HALF-KEY IN THE KEYWAY DURING BALANCING.
8 s$ r$ ^& n" N9 Y7 d4 ?; x半键连接？动平衡因该在整根轴带齿轮的装配体完成后整体做的，把这个要求写在这里应该要REF一个装配图要求。
4. PROTECT THESE SURFACES FROM SCRATCHES AND TOOL MARKS.
4 s2 B5 ~  W" k4 m; x保护刮伤正常，保护刀痕不正常。刀痕都是加工出来的，不存在保护就会消失。

？这是客户对供应商的产品需求吗？怎么看起来像打工做工艺分析的？
6. CASE CARBURISE AREA MARKED (**) AND HARDEN TO RC 58-64. FINISHED CASE DEPTH TO BE RC 50 AT 0.4-0.6 DEEP. REMAINDER TO BE RC 32-40
7. GRIND THE TEETH PER GEAR DATA AFTER HARDENING
' R5 _9 Q3 \: t8. DO NOT GRIND ROOT OF GEAR TOOTH. USE PROTUBERANT HOB.
这是不是滚压齿底的意思？用roll
9. ALL FILLET RADII TO BE CAREFULLY BLENDED, POLISHED AND FREE OF TOOL MARKS.
倒角处订个1.6的光洁度就行
10.UNLESS OTHERWISE SPECIFIED, CONCENTRICITY, SQUARENESS & PARALLELISM TO BE WITHIN 0.254 TIR
同轴度，垂直度，平行度都要有参照标准的，哪有可能没有specified啊？而且本身这3个值本身就是TIR，不需要说明
12.MAGNETIC PARTICLE TEST AND INSTPECT.
探伤之后要说哪些区域有伤可接受或者全部不接受
13.AFTER FINAL GRINDING, BLEND ALL SHARP EDGES, REMOVE ALL BURRS.
5 |. v) o9 n! R; ?: @我通常会用Break all burr. Sharp edge本身在机械零件里不是缺陷，该有的地方是你设计成它有。要是日用品就不能存在sharp edge。

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：

没有图纸怎么分析啊？楼上有图纸了？

无图无真相另，另外还要说一下功用。

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。
