蝸輪(lun)蝸桿減(jian)(jian)(jian)速機(ji)采用特殊結構的箱體(ti)，變(bian)(bian)滾動軸(zhou)承(cheng)(cheng)為滑(hua)動軸(zhou)承(cheng)(cheng)，建立液(ye)(ye)體(ti)摩擦(ca)潤(run)滑(hua)，改變(bian)(bian)軸(zhou)承(cheng)(cheng)潤(run)滑(hua)狀態。滑(hua)動軸(zhou)承(cheng)(cheng)，尤其是液(ye)(ye)體(ti)摩擦(ca)滑(hua)動軸(zhou)承(cheng)(cheng)具有回(hui)轉精度高、壽(shou)命(ming)長、摩阻低、耐沖擊和低噪(zao)聲等優點，用于蝸輪(lun)蝸桿減(jian)(jian)(jian)速機(ji)可(ke)大(da)大(da)提(ti)高傳動的平(ping)穩(wen)性并降低噪(zao)聲，為了探(tan)索RV減(jian)(jian)(jian)速機(ji)中(zhong)形成液(ye)(ye)體(ti)摩擦(ca)潤(run)滑(hua)的具體(ti)條件(jian)，本(ben)文就RV減(jian)(jian)(jian)速機(ji)中(zhong)蝸輪(lun)軸(zhou)止推滑(hua)動軸(zhou)承(cheng)(cheng)潤(run)滑(hua)狀態進行(xing)了測試和分(fen)析,并提(ti)出(chu)了結構設(she)計改善措施。

止(zhi)推(tui)(tui)滑(hua)(hua)動(dong)(dong)(dong)(dong)軸承(cheng)(cheng)(cheng)(cheng)的(de)結構型式(shi)：是(shi)利(li)用蝸輪(lun)輪(lun)轂端面(mian)(mian)(mian)（圓環面(mian)(mian)(mian)）與箱(xiang)體(ti)(ti)接(jie)觸面(mian)(mian)(mian)間(jian)形(xing)成(cheng)階梯面(mian)(mian)(mian)油契止(zhi)推(tui)(tui)滑(hua)(hua)動(dong)(dong)(dong)(dong)軸承(cheng)(cheng)(cheng)(cheng)。階梯面(mian)(mian)(mian)瓦(wa)用于軸線(xian)垂(chui)直放(fang)置(zhi)(zhi)的(de)止(zhi)推(tui)(tui)滑(hua)(hua)動(dong)(dong)(dong)(dong)軸承(cheng)(cheng)(cheng)(cheng)中，在(zai)滿(man)足(zu)定的(de)條件的(de)要求時，可以形(xing)成(cheng)液體(ti)(ti)動(dong)(dong)(dong)(dong)壓潤(run)(run)(run)滑(hua)(hua)，壓力(li)分(fen)(fen)布呈三角(jiao)形(xing)，其(qi)大(da)壓力(li)在(zai)階梯變化(hua)處，階梯面(mian)(mian)(mian)與軸承(cheng)(cheng)(cheng)(cheng)載能(neng)力(li)較大(da)，是(shi)蝸輪(lun)蝸桿減速機止(zhi)推(tui)(tui)滑(hua)(hua)動(dong)(dong)(dong)(dong)的(de)佳油膜形(xing)狀，然而(er)在(zai)軸線(xian)水平(ping)放(fang)置(zhi)(zhi)時，由(you)于RV減速箱(xiang)止(zhi)推(tui)(tui)滑(hua)(hua)動(dong)(dong)(dong)(dong)軸承(cheng)(cheng)(cheng)(cheng)潤(run)(run)(run)滑(hua)(hua)面(mian)(mian)(mian)處于鉛垂(chui)位置(zhi)(zhi)，軸承(cheng)(cheng)(cheng)(cheng)中潤(run)(run)(run)滑(hua)(hua)油不(bu)(bu)易存(cun)儲(chu)，很(hen)難保(bao)證供油充分(fen)(fen)，加之(zhi)本(ben)(ben)裝置(zhi)(zhi)蝸輪(lun)軸轉速很(hen)低，又(you)只(zhi)有(you)個(ge)油契，這都不(bu)(bu)能(neng)滿(man)足(zu)液體(ti)(ti)動(dong)(dong)(dong)(dong)力(li)潤(run)(run)(run)滑(hua)(hua)的(de)基本(ben)(ben)要求，因此(ci)(ci)不(bu)(bu)能(neng)形(xing)成(cheng)液體(ti)(ti)摩擦潤(run)(run)(run)滑(hua)(hua)，而(er)只(zhi)能(neng)形(xing)成(cheng)混(hun)合摩擦潤(run)(run)(run)滑(hua)(hua)。經拆卸軸承(cheng)(cheng)(cheng)(cheng)，觀(guan)察軸承(cheng)(cheng)(cheng)(cheng)端面(mian)(mian)(mian)實際磨(mo)損情(qing)況可知，靠(kao)近軸承(cheng)(cheng)(cheng)(cheng)外(wai)環有(you)明顯的(de)磨(mo)亮區，此(ci)(ci)外(wai)，這種單油契容易引起軸承(cheng)(cheng)(cheng)(cheng)的(de)偏(pian)斜，般不(bu)(bu)宜(yi)采(cai)用。

為(wei)了改變RV減速機軸(zhou)承(cheng)的潤滑(hua)狀態(tai)，可采取如下措(cuo)施：在軸(zhou)承(cheng)的接(jie)(jie)觸(chu)面(mian)上加工多(duo)個階梯面(mian)油契，般不少于(yu)3個，以(yi)使載荷(he)均布(bu)，避免軸(zhou)偏斜，而且利于(yu)油模穩定；增設供油裝(zhuang)置和(he)阻油邊(bian)，保(bao)證止推滑(hua)動軸(zhou)承(cheng)供油充分(fen)；提高蝸輪蝸桿減速機軸(zhou)承(cheng)接(jie)(jie)觸(chu)面(mian)的加工精度，這樣(yang)可以(yi)通(tong)過改變箱體結構來實現，以(yi)便于(yu)軸(zhou)承(cheng)接(jie)(jie)觸(chu)面(mian)的磨(mo)削。此外，將(jiang)液體摩(mo)擦潤滑(hua)的滑(hua)動軸(zhou)承(cheng)應用于(yu)斜齒輪減速機蝸桿的止推軸(zhou)承(cheng)中，還必須要作(zuo)進步(bu)的理論分(fen)析(xi)和(he)優化設計(ji)
