[4A] 這張齒輪圖紙的技術說明，你能看出哪里需要完善？

十年一夢

大家討論一下有什么需要完善之處。

機械神話

希望看到這張圖，機械圖紙是圖文并存的，不可分離。

這是你自己出圖紙給鬼佬加工的？

% s, d0 j7 ~, w) d材質(zhì)應寫入材質(zhì)欄，這里只要寫熱處理方式和最終硬度

這里的軸可能用axis比較合適，因為這根軸線不是實際存在的東西，同軸度本身就是個跳動值所以不用TIR。更應該直接標在圖上。
3.DYNAMICALLY BALANCE WITHING 0.26 OZ-IN AT PLANES INDICATED INSTALL HALF-KEY IN THE KEYWAY DURING BALANCING.
半鍵連接？動平衡因該在整根軸帶齒輪的裝配體完成后整體做的，把這個要求寫在這里應該要REF一個裝配圖要求。
4. PROTECT THESE SURFACES FROM SCRATCHES AND TOOL MARKS.
' r, x' z7 U0 Y: D' u, @; ]保護刮傷正常，保護刀痕不正常。刀痕都是加工出來的，不存在保護就會消失。
5. WHILE HOBBING LEAVE .29-.30 GRINDING STOCK TO FINISH THE GEAR.

這是不是滾壓齒底的意思？用roll
9. ALL FILLET RADII TO BE CAREFULLY BLENDED, POLISHED AND FREE OF TOOL MARKS.
1 t+ u& j2 E7 Q, \$ h倒角處訂個1.6的光潔度就行

. G& S+ ~! v9 b! k% E7 F同軸度，垂直度，平行度都要有參照標準的，哪有可能沒有specified啊？而且本身這3個值本身就是TIR，不需要說明
12.MAGNETIC PARTICLE TEST AND INSTPECT.
探傷之后要說哪些區(qū)域有傷可接受或者全部不接受

14.BURNISH MARKED AREA WITH (*).

老兄的東西每次看都有新發(fā)現(xiàn)。但是如果是一個齒輪的note，好像該有的東西全部沒有：

沒有圖紙怎么分析啊？樓上有圖紙了？

無圖無真相另，另外還要說一下功用。

高手啊，三樓

樓主你這應該是單個零件的技術要求吧？我覺得第三條動平衡應該去掉，單個零件的在這沒什么用；第五條磨削余量沒必要寫在這個里面吧，畢竟是工藝要求；另外，你要求表面刀紋看不出，那就直接定個粗糙度Ra1.6以下，這個可去參考粗糙度標準樣塊；第十條未注同心度0.254你有和第三條校核沒？單位是英制還是公制？有必要到小數(shù)點后三位？還有最后那條不太清楚你要干什么。
