F系(xi)列(lie)減(jian)速(su)(su)電機(ji)齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)面(mian)(mian)損(sun)傷的(de)(de)研究。平行(xing)(xing)軸減(jian)速(su)(su)機(ji)在使(shi)用(yong)過程中(zhong)經常會(hui)出現齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)面(mian)(mian)各種(zhong)不(bu)同類型的(de)(de)損(sun)傷，而齒(chi)(chi)(chi)(chi)面(mian)(mian)的(de)(de)損(sun)傷會(hui)直接影響到F系(xi)列(lie)減(jian)速(su)(su)電機(ji)的(de)(de)正常使(shi)用(yong)，嚴重的(de)(de)齒(chi)(chi)(chi)(chi)面(mian)(mian)損(sun)傷將(jiang)會(hui)造成平行(xing)(xing)軸減(jian)速(su)(su)機(ji)整(zheng)體失效，長(chang)期(qi)以來，對(dui)(dui)于(yu)平行(xing)(xing)軸減(jian)速(su)(su)機(ji)齒(chi)(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)(chi)面(mian)(mian)損(sun)傷的(de)(de)分類和應對(dui)(dui)策略沒有統的(de)(de)說法(fa)。

經過長期對齒(chi)輪制造過程的(de)跟蹤和F系列齒(chi)輪減速機裝配、工作過程及維修(xiu)工作的(de)研(yan)究，我們認為(wei)根(gen)據(ju)齒(chi)面(mian)損(sun)傷(shang)(shang)程度和方式(shi)的(de)不同，可將(jiang)齒(chi)面(mian)損(sun)傷(shang)(shang)歸結為(wei)五類(lei)(lei)(lei)損(sun)傷(shang)(shang)型式(shi)，即(ji)齒(chi)面(mian)磨(mo)損(sun)類(lei)(lei)(lei)型損(sun)傷(shang)(shang)、齒(chi)面(mian)疲勞類(lei)(lei)(lei)型損(sun)傷(shang)(shang)、齒(chi)面(mian)滑移(yi)膠合類(lei)(lei)(lei)型損(sun)傷(shang)(shang)、齒(chi)面(mian)塑性變形類(lei)(lei)(lei)型損(sun)傷(shang)(shang)和齒(chi)面(mian)破壞性折(zhe)斷類(lei)(lei)(lei)型損(sun)傷(shang)(shang)。下(xia)面(mian)就大致講(jiang)下(xia)齒(chi)面(mian)磨(mo)損(sun)類(lei)(lei)(lei)型損(sun)傷(shang)(shang)的(de)特征。

磨(mo)損(sun)是指齒(chi)(chi)(chi)輪(lun)的(de)(de)(de)(de)(de)(de)(de)齒(chi)(chi)(chi)面(mian)(mian)(mian)在嚙合傳動過(guo)程(cheng)(cheng)中，齒(chi)(chi)(chi)表(biao)面(mian)(mian)(mian)的(de)(de)(de)(de)(de)(de)(de)材(cai)料(liao)經摩擦損(sun)耗(hao)的(de)(de)(de)(de)(de)(de)(de)現(xian)象，俗稱(cheng)齒(chi)(chi)(chi)面(mian)(mian)(mian)“磨(mo)薄(bo)了(le)”。此(ci)類磨(mo)損(sun)情況(kuang)多出(chu)現(xian)在粉塵較(jiao)多的(de)(de)(de)(de)(de)(de)(de)場合使用下的(de)(de)(de)(de)(de)(de)(de)平(ping)行軸減(jian)速機中，根據齒(chi)(chi)(chi)面(mian)(mian)(mian)的(de)(de)(de)(de)(de)(de)(de)磨(mo)損(sun)情況(kuang)，又可(ke)分(fen)為以下四類情況(kuang)：輕(qing)微磨(mo)損(sun)：是種相當緩慢的(de)(de)(de)(de)(de)(de)(de)磨(mo)損(sun)現(xian)象，磨(mo)損(sun)的(de)(de)(de)(de)(de)(de)(de)過(guo)程(cheng)(cheng)是將相互(hu)接(jie)觸(chu)齒(chi)(chi)(chi)面(mian)(mian)(mian)表(biao)面(mian)(mian)(mian)止的(de)(de)(de)(de)(de)(de)(de)微小凸面(mian)(mian)(mian)（或凸點）逐(zhu)漸磨(mo)平(ping)到(dao)非常(chang)(chang)光滑(hua)(hua)的(de)(de)(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)，齒(chi)(chi)(chi)面(mian)(mian)(mian)的(de)(de)(de)(de)(de)(de)(de)微凸在工作過(guo)程(cheng)(cheng)平(ping)衡且微量(liang)，實(shi)際(ji)起(qi)到(dao)相嚙合齒(chi)(chi)(chi)面(mian)(mian)(mian)在傳動過(guo)程(cheng)(cheng)中相互(hu)研齒(chi)(chi)(chi)與(yu)磨(mo)合作用。中等磨(mo)損(sun)是種經常(chang)(chang)發生的(de)(de)(de)(de)(de)(de)(de)磨(mo)損(sun)現(xian)象。在F系列減(jian)速電機齒(chi)(chi)(chi)輪(lun)接(jie)觸(chu)齒(chi)(chi)(chi)面(mian)(mian)(mian)的(de)(de)(de)(de)(de)(de)(de)全齒(chi)(chi)(chi)向范圍內，沿(yan)節(jie)線(xian)附近(jin)的(de)(de)(de)(de)(de)(de)(de)齒(chi)(chi)(chi)面(mian)(mian)(mian)的(de)(de)(de)(de)(de)(de)(de)材(cai)料(liao)有明顯的(de)(de)(de)(de)(de)(de)(de)流(liu)失(shi)，離節(jie)線(xian)愈遠(yuan)流(liu)失(shi)得(de)越(yue)多，即磨(mo)損(sun)量(liang)就越(yue)大，僅(jin)在節(jie)線(xian)處(chu)出(chu)現(xian)條較(jiao)明顯的(de)(de)(de)(de)(de)(de)(de)連續線(xian)條，原始(shi)齒(chi)(chi)(chi)廓變得(de)不規則(ze)了(le)，用眼睛直(zhi)接(jie)觀察到(dao)的(de)(de)(de)(de)(de)(de)(de)結果是齒(chi)(chi)(chi)面(mian)(mian)(mian)不同程(cheng)(cheng)度(du)地(di)減(jian)薄(bo)了(le)，造成(cheng)平(ping)行軸減(jian)速箱齒(chi)(chi)(chi)輪(lun)磨(mo)齒(chi)(chi)(chi)現(xian)象的(de)(de)(de)(de)(de)(de)(de)原因，是由于潤(run)(run)滑(hua)(hua)系統中進入了(le)磨(mo)粒雜質(zhi)或潤(run)(run)滑(hua)(hua)劑性能降低，致使齒(chi)(chi)(chi)面(mian)(mian)(mian)在遠(yuan)離節(jie)線(xian)處(chu)出(chu)現(xian)邊界臨界潤(run)(run)滑(hua)(hua)狀(zhuang)態，瞬時出(chu)現(xian)干接(jie)觸(chu)。

過渡磨(mo)損(sun)(sun)是F系(xi)列(lie)(lie)減(jian)(jian)速(su)電機齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪中常見(jian)的(de)(de)種(zhong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)面磨(mo)損(sun)(sun)，在接(jie)觸齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)面的(de)(de)全齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)向(xiang)范圍(wei)內，平(ping)(ping)行軸(zhou)減(jian)(jian)速(su)機齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)面材料大量(liang)流失，呈(cheng)現(xian)種(zhong)明顯的(de)(de)瘦身(shen)型齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓，原(yuan)(yuan)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)廓形(xing)狀被徹(che)底破壞，齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)厚(hou)減(jian)(jian)薄，同時在節(jie)線附近同時迸發點蝕(shi)現(xian)象，使平(ping)(ping)行軸(zhou)減(jian)(jian)速(su)機傳動噪聲增大，運動系(xi)統(tong)振(zhen)動強烈(lie)，運轉(zhuan)極(ji)不(bu)平(ping)(ping)衡，齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪副不(bu)能正常工(gong)作，降(jiang)低了F系(xi)列(lie)(lie)減(jian)(jian)速(su)電機的(de)(de)使用壽命，產生此現(xian)象的(de)(de)原(yuan)(yuan)因是潤滑系(xi)統(tong)和密封裝置不(bu)嚴(yan)實，齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)面油(you)膜難(nan)以形(xing)成(cheng)，磨(mo)粒雜質(zhi)大量(liang)進入嚙(nie)合區，在沖擊(ji)載荷和長期超負荷工(gong)況的(de)(de)同時作用下(xia)，加劇摩擦磨(mo)損(sun)(sun)。腐蝕(shi)磨(mo)損(sun)(sun)是由于某些帶腐蝕(shi)性(xing)活性(xing)成(cheng)份進入潤滑系(xi)統(tong)，齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)面接(jie)觸過程(cheng)中使齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)面材料產生化(hua)學反應(ying)和電化(hua)學反應(ying)，而引起齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)面局部破壞，沿齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)高方向(xiang)均勻(yun)分布(bu)的(de)(de)腐蝕(shi)磨(mo)坑，嚴(yan)重時可使齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)面齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)形(xing)發生改變。
