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(you)于異形(xing)齒(chi)(chi)(chi)輪種類繁多，形(xing)狀復雜，給(gei)制造帶(dai)來一定(ding)的困(kun)難。加工(gong)異形(xing)齒(chi)(chi)(chi)輪有(you)很多方法。根據齒(chi)(chi)(chi)形(xing)形(xing)成的原理，有(you)成形(xing)法和生成法。從加工(gong)方法上分為銑(xian)齒(chi)(chi)(chi)、開槽(cao)齒(chi)(chi)(chi)、滾(gun)齒(chi)(chi)(chi)和線切割。當今運用(yong)最廣的是在數控(kong)(kong)機(ji)(ji)床插齒(chi)(chi)(chi)機(ji)(ji)上，用(yong)規范的傳動(dong)齒(chi)(chi)(chi)輪插刀生產加工(gong)，或在數控(kong)(kong)滾(gun)齒(chi)(chi)(chi)機(ji)(ji)上，用(yong)齒(chi)(chi)(chi)輪齒(chi)(chi)(chi)條形(xing)數控(kong)(kong)刀片或規范的傳動(dong)齒(chi)(chi)(chi)輪滾(gun)刀生產加工(gong)。
