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(yu)異形(xing)(xing)齒(chi)(chi)(chi)(chi)輪(lun)(lun)種類繁(fan)多，形(xing)(xing)狀(zhuang)復(fu)雜(za)，給(gei)制造(zao)帶來一定的(de)困難。加(jia)(jia)(jia)工異形(xing)(xing)齒(chi)(chi)(chi)(chi)輪(lun)(lun)有很多方法。根據(ju)齒(chi)(chi)(chi)(chi)形(xing)(xing)形(xing)(xing)成(cheng)的(de)原理，有成(cheng)形(xing)(xing)法和生成(cheng)法。從(cong)加(jia)(jia)(jia)工方法上(shang)分為銑齒(chi)(chi)(chi)(chi)、開槽(cao)齒(chi)(chi)(chi)(chi)、滾(gun)齒(chi)(chi)(chi)(chi)和線(xian)切割(ge)。當今運用(yong)最廣的(de)是在數(shu)控(kong)(kong)機(ji)床插齒(chi)(chi)(chi)(chi)機(ji)上(shang)，用(yong)規范(fan)的(de)傳動(dong)齒(chi)(chi)(chi)(chi)輪(lun)(lun)插刀(dao)生產加(jia)(jia)(jia)工，或在數(shu)控(kong)(kong)滾(gun)齒(chi)(chi)(chi)(chi)機(ji)上(shang)，用(yong)齒(chi)(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)(chi)條形(xing)(xing)數(shu)控(kong)(kong)刀(dao)片(pian)或規范(fan)的(de)傳動(dong)齒(chi)(chi)(chi)(chi)輪(lun)(lun)滾(gun)刀(dao)生產加(jia)(jia)(jia)工。
