隨(sui)著科學技術(shu)的(de)發展，珩(heng)齒(chi)(chi)(chi)(chi)已經由一種附加(jia)的(de)非必須的(de)齒(chi)(chi)(chi)(chi)輪(lun)精加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)，發展為可以(yi)改(gai)善齒(chi)(chi)(chi)(chi)面幾何形狀(zhuang)，具(ju)有(you)立(li)加(jia)工(gong)(gong)(gong)能力(li)的(de)強(qiang)力(li)珩(heng)工(gong)(gong)(gong)藝(yi)。這使得珩(heng)齒(chi)(chi)(chi)(chi)工(gong)(gong)(gong)藝(yi)逐漸和(he)磨齒(chi)(chi)(chi)(chi)一起成為齒(chi)(chi)(chi)(chi)輪(lun)加(jia)工(gong)(gong)(gong)整套工(gong)(gong)(gong)藝(yi)流程(cheng)中(zhong)(zhong)終也關鍵的(de)步驟。但(dan)珩(heng)齒(chi)(chi)(chi)(chi)和(he)磨齒(chi)(chi)(chi)(chi)在加(jia)工(gong)(gong)(gong)不(bu)同需求的(de)齒(chi)(chi)(chi)(chi)輪(lun)上(shang)，有(you)著不(bu)同的(de)適用條件和(he)范圍。根據加(jia)工(gong)(gong)(gong)方式(shi)(shi)，珩(heng)齒(chi)(chi)(chi)(chi)工(gong)(gong)(gong)藝(yi)分為：外嚙(nie)合珩(heng)齒(chi)(chi)(chi)(chi)、內(nei)嚙(nie)合珩(heng)齒(chi)(chi)(chi)(chi)和(he)蝸桿(gan)式(shi)(shi)珩(heng)齒(chi)(chi)(chi)(chi)3種。其(qi)中(zhong)(zhong)，蝸桿(gan)珩(heng)齒(chi)(chi)(chi)(chi)具(ju)有(you)切(qie)削(xue)速度較、修(xiu)(xiu)正輪(lun)齒(chi)(chi)(chi)(chi)誤差能力(li)強(qiang)、生產成本低(di)等特點，蝸桿(gan)珩(heng)輪(lun)磨損后還可進行(xing)多次修(xiu)(xiu)整使用。

 珩(heng)(heng)齒(chi)(chi)是在(zai)(zai)加(jia)(jia)工過程中，借助珩(heng)(heng)磨輪和工件(jian)齒(chi)(chi)輪的(de)(de)(de)(de)齒(chi)(chi)面相(xiang)對滑動(dong)(dong)進(jin)行加(jia)(jia)工作業。加(jia)(jia)工齒(chi)(chi)面上(shang)接觸點的(de)(de)(de)(de)相(xiang)對速度運(yun)動(dong)(dong)方(fang)向取(qu)決(jue)于珩(heng)(heng)磨輪和工件(jian)的(de)(de)(de)(de)軸(zhou)線的(de)(de)(de)(de)夾(jia)角。沿(yan)著工件(jian)齒(chi)(chi)向方(fang)向的(de)(de)(de)(de)相(xiang)對滑動(dong)(dong)，與沿(yan)齒(chi)(chi)形方(fang)向的(de)(de)(de)(de)展成運(yun)動(dong)(dong)結合起(qi)來，形成了(le)接觸點處的(de)(de)(de)(de)相(xiang)對運(yun)動(dong)(dong)。兩個(ge)方(fang)向的(de)(de)(de)(de)滑動(dong)(dong)運(yun)動(dong)(dong)的(de)(de)(de)(de)疊力，終在(zai)(zai)齒(chi)(chi)面上(shang)產(chan)生的(de)(de)(de)(de)加(jia)(jia)工弧線紋理。

 加工時相(xiang)對速度(du)的控制對齒(chi)面(mian)(mian)表面(mian)(mian)特(te)征的形(xing)成(cheng)有著決(jue)定(ding)性作用。為揭示(shi)其內在聯系，我們從漸開過程中，齒(chi)面(mian)(mian)接觸位置(zhi)與加工相(xiang)對速度(du)的關系，并(bing)以(yi)加工固定(ding)參(can)(can)數的齒(chi)輪為條件，研究影響相(xiang)對速度(du)的珩磨(mo)輪參(can)(can)數，并(bing)進行珩磨(mo)輪優化設計。
