[4A] 這張齒輪圖紙的技術(shù)說明，你能看出哪里需要完善？

十年一夢(mèng)

大家討論一下有什么需要完善之處。

機(jī)械神話

希望看到這張圖，機(jī)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？
1. MATERIAL: ALLOY STEEL 9310H-NORMALIZED & TEMPERED TP HRc 32-40.(AIR CRAFT QUALITY FORGING).
材質(zhì)應(yīng)寫入材質(zhì)欄，這里只要寫熱處理方式和最終硬度
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.
這里的軸可能用axis比較合適，因?yàn)檫@根軸線不是實(shí)際存在的東西，同軸度本身就是個(gè)跳動(dòng)值所以不用TIR。更應(yīng)該直接標(biāo)在圖上。
( b0 m2 |$ Y& }" f3 `3.DYNAMICALLY BALANCE WITHING 0.26 OZ-IN AT PLANES INDICATED INSTALL HALF-KEY IN THE KEYWAY DURING BALANCING.
半鍵連接？動(dòng)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(gè)要求寫在這里應(yīng)該要REF一個(gè)裝配圖要求。
4. PROTECT THESE SURFACES FROM SCRATCHES AND TOOL MARKS.
保護(hù)刮傷正常，保護(hù)刀痕不正常。刀痕都是加工出來的，不存在保護(hù)就會(huì)消失。
5. WHILE HOBBING LEAVE .29-.30 GRINDING STOCK TO FINISH THE GEAR.
？這是客戶對(duì)供應(yīng)商的產(chǎn)品需求嗎？怎么看起來像打工做工藝分析的？

高手啊，三樓

樓主你這應(yīng)該是單個(gè)零件的技術(shù)要求吧？我覺得第三條動(dòng)平衡應(yīng)該去掉，單個(gè)零件的在這沒什么用；第五條磨削余量沒必要寫在這個(gè)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(gè)粗糙度Ra1.6以下，這個(gè)可去參考粗糙度標(biāo)準(zhǔn)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(diǎn)后三位？還有最后那條不太清楚你要干什么。
