[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？

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,。
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,。

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。
