蝸輪(lun)蝸桿的(de)(de)加(jia)工(gong)(gong)(gong)方(fang)法(fa)(fa)(fa)(fa) 蝸輪(lun)蝸桿的(de)(de)加(jia)工(gong)(gong)(gong)方(fang)法(fa)(fa)(fa)(fa)很多，如切削(xue)、鑄造、軋制、沖壓(ya)等，其中常用的(de)(de)是(shi)切削(xue)加(jia)工(gong)(gong)(gong)方(fang)法(fa)(fa)(fa)(fa)。切削(xue)加(jia)工(gong)(gong)(gong)方(fang)法(fa)(fa)(fa)(fa)分為成形(xing)(xing)法(fa)(fa)(fa)(fa)和范成法(fa)(fa)(fa)(fa)兩(liang)類。 1．成形(xing)(xing)法(fa)(fa)(fa)(fa) 成形(xing)(xing)法(fa)(fa)(fa)(fa)是(shi)在銑(xian)床上用具有(you)漸開線齒(chi)(chi)(chi)(chi)形(xing)(xing)的(de)(de)成形(xing)(xing)銑(xian)刀(dao)(dao)直接切出(chu)齒(chi)(chi)(chi)(chi)形(xing)(xing)。常用的(de)(de)有(you)圓盤銑(xian)刀(dao)(dao)和指狀銑(xian)刀(dao)(dao)兩(liang)種(zhong)(zhong)。切齒(chi)(chi)(chi)(chi)加(jia)工(gong)(gong)(gong)時，銑(xian)刀(dao)(dao)旋轉(zhuan)，同(tong)時輪(lun)坯(pi)(pi)沿(yan)齒(chi)(chi)(chi)(chi)輪(lun)軸(zhou)線方(fang)向(xiang)移動。銑(xian)出(chu)一(yi)個(ge)齒(chi)(chi)(chi)(chi)槽(cao)以(yi)(yi)后，將輪(lun)坯(pi)(pi)轉(zhuan)過360°/z，再銑(xian)第二個(ge)齒(chi)(chi)(chi)(chi)槽(cao)。其余依此類推。 這(zhe)種(zhong)(zhong)切齒(chi)(chi)(chi)(chi)方(fang)法(fa)(fa)(fa)(fa)簡單(dan)，不(bu)需(xu)要(yao)專用機床，但生(sheng)產率低(di)，精度(du)(du)低(di)，故僅適用單(dan)件或小批量生(sheng)產及精度(du)(du)要(yao)求不(bu)高(gao)的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)加(jia)工(gong)(gong)(gong)。 2．范成法(fa)(fa)(fa)(fa) 范成法(fa)(fa)(fa)(fa)是(shi)利用齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)嚙合原理進行(xing)加(jia)工(gong)(gong)(gong)齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)一(yi)種(zhong)(zhong)方(fang)法(fa)(fa)(fa)(fa)。這(zhe)種(zhong)(zhong)方(fang)法(fa)(fa)(fa)(fa)強制刀(dao)(dao)具同(tong)工(gong)(gong)(gong)件（輪(lun)坯(pi)(pi)）相(xiang)對(dui)運(yun)動同(tong)時進行(xing)切削(xue)。它們之(zhi)間的(de)(de)運(yun)動關系同(tong)一(yi)對(dui)齒(chi)(chi)(chi)(chi)輪(lun)嚙合一(yi)樣(yang)，以(yi)(yi)此來(lai)保證齒(chi)(chi)(chi)(chi)形(xing)(xing)的(de)(de)正確和分齒(chi)(chi)(chi)(chi)的(de)(de)均勻。對(dui)于模數(shu)m和壓(ya)力角(jiao)a都(dou)相(xiang)同(tong)而齒(chi)(chi)(chi)(chi)數(shu)不(bu)同(tong)的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)，可(ke)以(yi)(yi)用同(tong)一(yi)刀(dao)(dao)具進行(xing)加(jia)工(gong)(gong)(gong)。
