蝸輪蝸桿
雙導程(cheng)蝸(gua)桿(gan)的加(jia)工(gong)(gong)方法(fa)(fa):雙導程(cheng)蝸(gua)桿(gan)的加(jia)工(gong)(gong)方法(fa)(fa)很多(duo),如切(qie)(qie)削、鑄造(zao)、軋制、沖壓等(deng),其中常(chang)用(yong)的是(shi)(shi)切(qie)(qie)削加(jia)工(gong)(gong)方法(fa)(fa)。切(qie)(qie)削加(jia)工(gong)(gong)方法(fa)(fa)分為(wei)成形(xing)(xing)法(fa)(fa)和(he)范(fan)成法(fa)(fa)兩類(lei)。 1.成形(xing)(xing)法(fa)(fa) 成形(xing)(xing)法(fa)(fa)是(shi)(shi)在銑床上用(yong)具(ju)有(you)漸開線齒(chi)(chi)(chi)形(xing)(xing)的成形(xing)(xing)銑刀(dao)(dao)(dao)直(zhi)接切(qie)(qie)出齒(chi)(chi)(chi)形(xing)(xing)。常(chang)用(yong)的有(you)圓盤銑刀(dao)(dao)(dao)和(he)指狀銑刀(dao)(dao)(dao)兩種(zhong)。切(qie)(qie)齒(chi)(chi)(chi)加(jia)工(gong)(gong)時,銑刀(dao)(dao)(dao)旋(xuan)轉(zhuan),同(tong)時輪(lun)(lun)(lun)坯(pi)沿齒(chi)(chi)(chi)輪(lun)(lun)(lun)軸線方向移動。銑出一(yi)個齒(chi)(chi)(chi)槽(cao)以(yi)(yi)后(hou),將輪(lun)(lun)(lun)坯(pi)轉(zhuan)過360°/z,再(zai)銑第二個齒(chi)(chi)(chi)槽(cao)。其余依此(ci)類(lei)推。 這種(zhong)切(qie)(qie)齒(chi)(chi)(chi)方法(fa)(fa)簡單,不(bu)(bu)需要(yao)專用(yong)機床,但(dan)生產率低(di),精(jing)度低(di),故(gu)僅適用(yong)單件或小(xiao)批量生產及(ji)精(jing)度要(yao)求(qiu)不(bu)(bu)高的齒(chi)(chi)(chi)輪(lun)(lun)(lun)加(jia)工(gong)(gong)。 2.范(fan)成法(fa)(fa) 范(fan)成法(fa)(fa)是(shi)(shi)利(li)用(yong)齒(chi)(chi)(chi)輪(lun)(lun)(lun)的嚙合(he)原(yuan)理進行加(jia)工(gong)(gong)齒(chi)(chi)(chi)輪(lun)(lun)(lun)的一(yi)種(zhong)方法(fa)(fa)。這種(zhong)方法(fa)(fa)強制刀(dao)(dao)(dao)具(ju)同(tong)工(gong)(gong)件(輪(lun)(lun)(lun)坯(pi))相對運(yun)動同(tong)時進行切(qie)(qie)削。它們(men)之間(jian)的運(yun)動關(guan)系同(tong)一(yi)對齒(chi)(chi)(chi)輪(lun)(lun)(lun)嚙合(he)一(yi)樣,以(yi)(yi)此(ci)來保證(zheng)齒(chi)(chi)(chi)形(xing)(xing)的正確和(he)分齒(chi)(chi)(chi)的均勻(yun)。對于模數m和(he)壓力角a都相同(tong)而齒(chi)(chi)(chi)數不(bu)(bu)同(tong)的齒(chi)(chi)(chi)輪(lun)(lun)(lun),可以(yi)(yi)用(yong)同(tong)一(yi)刀(dao)(dao)(dao)具(ju)進行加(jia)工(gong)(gong)。
