兆威介紹蝸桿狀珩磨輪對珩齒速度的影響研究
隨(sui)著(zhu)科(ke)學(xue)技術(shu)的(de)(de)(de)發展,珩(heng)(heng)齒(chi)(chi)(chi)已經(jing)由一種附加(jia)的(de)(de)(de)非必須的(de)(de)(de)齒(chi)(chi)(chi)輪精加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝,發展為可(ke)以改善齒(chi)(chi)(chi)面幾何形(xing)狀,具有(you)(you)立加(jia)工(gong)(gong)(gong)能力的(de)(de)(de)強力珩(heng)(heng)工(gong)(gong)(gong)藝。這使(shi)得珩(heng)(heng)齒(chi)(chi)(chi)工(gong)(gong)(gong)藝逐漸和(he)(he)磨齒(chi)(chi)(chi)一起成為齒(chi)(chi)(chi)輪加(jia)工(gong)(gong)(gong)整套工(gong)(gong)(gong)藝流程中終也關鍵的(de)(de)(de)步驟(zou)。但珩(heng)(heng)齒(chi)(chi)(chi)和(he)(he)磨齒(chi)(chi)(chi)在加(jia)工(gong)(gong)(gong)不(bu)同需求的(de)(de)(de)齒(chi)(chi)(chi)輪上,有(you)(you)著(zhu)不(bu)同的(de)(de)(de)適(shi)用(yong)條件和(he)(he)范圍。根據加(jia)工(gong)(gong)(gong)方式,珩(heng)(heng)齒(chi)(chi)(chi)工(gong)(gong)(gong)藝分為:外嚙(nie)合(he)珩(heng)(heng)齒(chi)(chi)(chi)、內嚙(nie)合(he)珩(heng)(heng)齒(chi)(chi)(chi)和(he)(he)蝸桿式珩(heng)(heng)齒(chi)(chi)(chi)3種。其中,蝸桿珩(heng)(heng)齒(chi)(chi)(chi)具有(you)(you)切削速度(du)較、修(xiu)正(zheng)輪齒(chi)(chi)(chi)誤差能力強、生產(chan)成本(ben)低等特點,蝸桿珩(heng)(heng)輪磨損(sun)后還可(ke)進行多次修(xiu)整使(shi)用(yong)。
珩(heng)(heng)齒(chi)(chi)是在加(jia)工過程(cheng)中,借(jie)助珩(heng)(heng)磨輪(lun)和工件(jian)(jian)齒(chi)(chi)輪(lun)的(de)(de)(de)(de)(de)齒(chi)(chi)面(mian)相對(dui)(dui)滑動(dong)(dong)進(jin)行加(jia)工作業。加(jia)工齒(chi)(chi)面(mian)上(shang)接(jie)觸點(dian)的(de)(de)(de)(de)(de)相對(dui)(dui)速度(du)運動(dong)(dong)方(fang)向(xiang)(xiang)取決于珩(heng)(heng)磨輪(lun)和工件(jian)(jian)的(de)(de)(de)(de)(de)軸線的(de)(de)(de)(de)(de)夾角。沿(yan)著工件(jian)(jian)齒(chi)(chi)向(xiang)(xiang)方(fang)向(xiang)(xiang)的(de)(de)(de)(de)(de)相對(dui)(dui)滑動(dong)(dong),與(yu)沿(yan)齒(chi)(chi)形方(fang)向(xiang)(xiang)的(de)(de)(de)(de)(de)展成(cheng)(cheng)運動(dong)(dong)結合起來,形成(cheng)(cheng)了接(jie)觸點(dian)處的(de)(de)(de)(de)(de)相對(dui)(dui)運動(dong)(dong)。兩個方(fang)向(xiang)(xiang)的(de)(de)(de)(de)(de)滑動(dong)(dong)運動(dong)(dong)的(de)(de)(de)(de)(de)疊力,終(zhong)在齒(chi)(chi)面(mian)上(shang)產生的(de)(de)(de)(de)(de)加(jia)工弧線紋理。
加(jia)工(gong)時相(xiang)對(dui)速度的(de)控制對(dui)齒面(mian)表面(mian)特征的(de)形成(cheng)有著決定(ding)性(xing)作用。為揭(jie)示(shi)其內在聯(lian)系(xi),我們從(cong)漸開過程中(zhong),齒面(mian)接(jie)觸位置與加(jia)工(gong)相(xiang)對(dui)速度的(de)關系(xi),并以加(jia)工(gong)固定(ding)參數的(de)齒輪(lun)為條件,研究影(ying)響相(xiang)對(dui)速度的(de)珩(heng)磨輪(lun)參數,并進(jin)行珩(heng)磨輪(lun)優(you)化設計。
