[4A] 這張齒輪圖紙的技術(shù)說(shuō)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。

樓主你這應(yīng)該是單個(gè)零件的技術(shù)要求吧？我覺(jué)得第三條動(dòng)平衡應(yīng)該去掉,，單個(gè)零件的在這沒(méi)什么用,；第五條磨削余量沒(méi)必要寫(xiě)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(méi)？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。
