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)輪(lun)種類繁多，形(xing)(xing)狀復雜(za)，給制造帶來一(yi)定的困難。加(jia)工(gong)異形(xing)(xing)齒(chi)(chi)(chi)輪(lun)有很(hen)多方(fang)法。根據齒(chi)(chi)(chi)形(xing)(xing)形(xing)(xing)成(cheng)的原(yuan)理，有成(cheng)形(xing)(xing)法和(he)生(sheng)成(cheng)法。從加(jia)工(gong)方(fang)法上分(fen)為銑齒(chi)(chi)(chi)、開槽齒(chi)(chi)(chi)、滾(gun)齒(chi)(chi)(chi)和(he)線(xian)切割。當今運用最廣(guang)的是在數控(kong)(kong)(kong)機床插(cha)齒(chi)(chi)(chi)機上，用規(gui)范的傳動齒(chi)(chi)(chi)輪(lun)插(cha)刀(dao)生(sheng)產加(jia)工(gong)，或(huo)在數控(kong)(kong)(kong)滾(gun)齒(chi)(chi)(chi)機上，用齒(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)條形(xing)(xing)數控(kong)(kong)(kong)刀(dao)片或(huo)規(gui)范的傳動齒(chi)(chi)(chi)輪(lun)滾(gun)刀(dao)生(sheng)產加(jia)工(gong)。
