蝸輪(lun)(lun)(lun)蝸桿的(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)(fang)(fang)法(fa)(fa)(fa) 蝸輪(lun)(lun)(lun)蝸桿的(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)(fang)(fang)法(fa)(fa)(fa)很多，如切(qie)(qie)削、鑄造、軋制、沖壓等，其(qi)中常用(yong)的(de)(de)是(shi)(shi)切(qie)(qie)削加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)(fang)(fang)法(fa)(fa)(fa)。切(qie)(qie)削加(jia)(jia)工(gong)(gong)(gong)(gong)方(fang)(fang)(fang)法(fa)(fa)(fa)分為成形(xing)法(fa)(fa)(fa)和范成法(fa)(fa)(fa)兩(liang)類。 1．成形(xing)法(fa)(fa)(fa) 成形(xing)法(fa)(fa)(fa)是(shi)(shi)在(zai)銑(xian)床上用(yong)具(ju)有漸開線齒(chi)(chi)(chi)(chi)形(xing)的(de)(de)成形(xing)銑(xian)刀直接切(qie)(qie)出齒(chi)(chi)(chi)(chi)形(xing)。常用(yong)的(de)(de)有圓(yuan)盤(pan)銑(xian)刀和指狀銑(xian)刀兩(liang)種。切(qie)(qie)齒(chi)(chi)(chi)(chi)加(jia)(jia)工(gong)(gong)(gong)(gong)時(shi)，銑(xian)刀旋轉，同時(shi)輪(lun)(lun)(lun)坯沿齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)軸線方(fang)(fang)(fang)向移動。銑(xian)出一(yi)個齒(chi)(chi)(chi)(chi)槽以(yi)后，將輪(lun)(lun)(lun)坯轉過(guo)360°/z，再銑(xian)第二(er)個齒(chi)(chi)(chi)(chi)槽。其(qi)余依(yi)此類推。 這(zhe)(zhe)種切(qie)(qie)齒(chi)(chi)(chi)(chi)方(fang)(fang)(fang)法(fa)(fa)(fa)簡單(dan)，不(bu)需要專(zhuan)用(yong)機床，但(dan)生產(chan)率(lv)低，精度(du)低，故僅適用(yong)單(dan)件或小批(pi)量生產(chan)及精度(du)要求不(bu)高的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)加(jia)(jia)工(gong)(gong)(gong)(gong)。 2．范成法(fa)(fa)(fa) 范成法(fa)(fa)(fa)是(shi)(shi)利(li)用(yong)齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)(de)嚙合(he)原(yuan)理進(jin)(jin)行加(jia)(jia)工(gong)(gong)(gong)(gong)齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)的(de)(de)一(yi)種方(fang)(fang)(fang)法(fa)(fa)(fa)。這(zhe)(zhe)種方(fang)(fang)(fang)法(fa)(fa)(fa)強(qiang)制刀具(ju)同工(gong)(gong)(gong)(gong)件（輪(lun)(lun)(lun)坯）相(xiang)對(dui)(dui)運(yun)動同時(shi)進(jin)(jin)行切(qie)(qie)削。它們之間的(de)(de)運(yun)動關系同一(yi)對(dui)(dui)齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)嚙合(he)一(yi)樣，以(yi)此來(lai)保(bao)證齒(chi)(chi)(chi)(chi)形(xing)的(de)(de)正(zheng)確(que)和分齒(chi)(chi)(chi)(chi)的(de)(de)均勻(yun)。對(dui)(dui)于模數m和壓力角a都(dou)相(xiang)同而齒(chi)(chi)(chi)(chi)數不(bu)同的(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)，可(ke)以(yi)用(yong)同一(yi)刀具(ju)進(jin)(jin)行加(jia)(jia)工(gong)(gong)(gong)(gong)。
