異型齒輪也稱為非圓齒輪。分度曲面是非旋轉曲面的齒輪，與另一個齒輪組成齒輪對后，在嚙合過程中瞬時角速度比以一定的運動規則變化。iHF合發齒輪加工廠家加工生產定做異型齒輪，精度高、價格低、交期快。

由于異(yi)形(xing)(xing)(xing)(xing)齒(chi)(chi)輪(lun)種(zhong)類(lei)繁多，形(xing)(xing)(xing)(xing)狀復雜，給(gei)制造帶來一定的困難。加工(gong)(gong)異(yi)形(xing)(xing)(xing)(xing)齒(chi)(chi)輪(lun)有(you)很多方法。根據齒(chi)(chi)形(xing)(xing)(xing)(xing)形(xing)(xing)(xing)(xing)成(cheng)的原理，有(you)成(cheng)形(xing)(xing)(xing)(xing)法和生成(cheng)法。從加工(gong)(gong)方法上(shang)分為銑(xian)齒(chi)(chi)、開槽(cao)齒(chi)(chi)、滾齒(chi)(chi)和線切割。當今運用最廣(guang)的是在數(shu)控(kong)機床插(cha)(cha)齒(chi)(chi)機上(shang)，用規范的傳(chuan)動齒(chi)(chi)輪(lun)插(cha)(cha)刀(dao)生產加工(gong)(gong)，或(huo)(huo)在數(shu)控(kong)滾齒(chi)(chi)機上(shang)，用齒(chi)(chi)輪(lun)齒(chi)(chi)條形(xing)(xing)(xing)(xing)數(shu)控(kong)刀(dao)片或(huo)(huo)規范的傳(chuan)動齒(chi)(chi)輪(lun)滾刀(dao)生產加工(gong)(gong)。
