齒(chi)輪減(jian)速(su)(su)(su)(su)機通(tong)(tong)氣帽(mao)溢油的(de)(de)(de)結構改進JRTRX37減(jian)速(su)(su)(su)(su)機選(xuan)型樣本。齒(chi)輪減(jian)速(su)(su)(su)(su)機在相對油位(wei)(wei)(wei)較高的(de)(de)(de)部(bu)位(wei)(wei)(wei)設(she)(she)計通(tong)(tong)氣帽(mao)裝置(zhi)，其作用是(shi)(shi)維持(chi)(chi)齒(chi)輪減(jian)速(su)(su)(su)(su)電(dian)(dian)機內外(wai)部(bu)氣壓平衡，保持(chi)(chi)齒(chi)輪減(jian)速(su)(su)(su)(su)機各(ge)部(bu)位(wei)(wei)(wei)的(de)(de)(de)密封良好。但(dan)是(shi)(shi)齒(chi)輪減(jian)速(su)(su)(su)(su)機通(tong)(tong)氣帽(mao)部(bu)位(wei)(wei)(wei)經(jing)常發生溢油，而且(qie)這(zhe)種情況較難避免。為了查明通(tong)(tong)氣帽(mao)溢油的(de)(de)(de)真(zhen)正(zheng)原(yuan)因，專門(men)針對某臺(tai)齒(chi)輪減(jian)速(su)(su)(su)(su)機進行了改造，般將(jiang)通(tong)(tong)氣帽(mao)設(she)(she)計在齒(chi)輪減(jian)速(su)(su)(su)(su)電(dian)(dian)機機蓋上(shang)部(bu)的(de)(de)(de)視孔(kong)蓋上(shang)。為了方(fang)便觀(guan)察，就(jiu)將(jiang)齒(chi)輪減(jian)速(su)(su)(su)(su)機機蓋上(shang)的(de)(de)(de)視孔(kong)蓋改為有機玻璃(li)。

齒(chi)(chi)輪(lun)(lun)(lun)(lun)減(jian)(jian)速電機在正常運轉(zhuan)時，由于齒(chi)(chi)輪(lun)(lun)(lun)(lun)高(gao)速轉(zhuan)動，輪(lun)(lun)(lun)(lun)齒(chi)(chi)不(bu)斷從齒(chi)(chi)輪(lun)(lun)(lun)(lun)減(jian)(jian)速機箱體油(you)池內將潤(run)滑(hua)(hua)油(you)以(yi)油(you)流(liu)形式甩(shuai)到(dao)視孔蓋(gai)(gai)下的(de)(de)擋油(you)板(ban)(ban)上，進(jin)步通(tong)(tong)過通(tong)(tong)氣帽外(wai)溢(yi)。這(zhe)種潤(run)滑(hua)(hua)油(you)的(de)(de)外(wai)溢(yi)和齒(chi)(chi)輪(lun)(lun)(lun)(lun)減(jian)(jian)速機的(de)(de)正反向運轉(zhuan)、潤(run)滑(hua)(hua)油(you)的(de)(de)黏(nian)度(du)(du)(du)以(yi)及減(jian)(jian)速機運轉(zhuan)時間(jian)的(de)(de)長短等因素有關。查明原因后，對原來的(de)(de)通(tong)(tong)氣帽結(jie)構(gou)進(jin)行調整，為了不(bu)讓油(you)流(liu)甩(shuai)到(dao)通(tong)(tong)氣帽上，加大(da)了視孔蓋(gai)(gai)與下部擋油(you)板(ban)(ban)之間(jian)的(de)(de)高(gao)度(du)(du)(du)，同(tong)時加大(da)擋油(you)板(ban)(ban)的(de)(de)長度(du)(du)(du)和寬度(du)(du)(du)，擋油(you)板(ban)(ban)加高(gao)目(mu)的(de)(de)是讓甩(shuai)到(dao)擋油(you)板(ban)(ban)上部的(de)(de)油(you)流(liu)不(bu)聚集，可以(yi)隨時流(liu)走，就不(bu)會(hui)使(shi)油(you)流(liu)到(dao)達(da)齒(chi)(chi)輪(lun)(lun)(lun)(lun)減(jian)(jian)速電機通(tong)(tong)氣帽部位，也就不(bu)可能出現通(tong)(tong)氣帽溢(yi)油(you)現象(xiang)，加大(da)擋油(you)板(ban)(ban)的(de)(de)長度(du)(du)(du)和寬度(du)(du)(du)目(mu)的(de)(de)是減(jian)(jian)少被齒(chi)(chi)輪(lun)(lun)(lun)(lun)甩(shuai)上的(de)(de)油(you)流(liu)飛濺到(dao)通(tong)(tong)氣塞(sai)的(de)(de)可能性。改進(jin)完成(cheng)后繼續(xu)試驗，將潤(run)滑(hua)(hua)油(you)加到(dao)正常油(you)位，經過3小時正反向連(lian)續(xu)運轉(zhuan)，沒有出現溢(yi)油(you)現象(xiang)。

為了徹底(di)解決通氣(qi)(qi)帽溢(yi)(yi)油(you)(you)問題(ti)，模擬用(yong)(yong)戶(hu)使用(yong)(yong)現(xian)場將(jiang)(jiang)潤(run)滑(hua)油(you)(you)加(jia)多時(shi)會不(bu)會出現(xian)溢(yi)(yi)油(you)(you)現(xian)象(xiang)，將(jiang)(jiang)潤(run)滑(hua)油(you)(you)多加(jia)正(zheng)常值(zhi)的1/3，繼續試驗(yan)，運(yun)轉時(shi)間延長(chang)，通氣(qi)(qi)帽逐步出現(xian)溢(yi)(yi)油(you)(you)現(xian)象(xiang)，原因分(fen)析：齒輪減速馬達運(yun)轉時(shi)齒輪由于浸油(you)(you)深(shen)度的加(jia)大，所攜帶潤(run)滑(hua)油(you)(you)甩出的油(you)(you)流(liu)也(ye)變(bian)大，油(you)(you)流(liu)在(zai)齒輪減速電機(ji)內(nei)部的相互碰撞導致(zhi)潤(run)滑(hua)油(you)(you)飛(fei)濺(jian)也(ye)在(zai)加(jia)劇，此時(shi)擋油(you)(you)板已不(bu)能將(jiang)(jiang)全部油(you)(you)流(liu)擋住(zhu)。

考慮到實際(ji)用(yong)(yong)戶在(zai)(zai)使(shi)用(yong)(yong)中加(jia)(jia)油(you)(you)(you)(you)過(guo)(guo)量情(qing)況(kuang)不(bu)(bu)可能(neng)(neng)徹底避(bi)免，且加(jia)(jia)油(you)(you)(you)(you)量偏(pian)小將(jiang)會(hui)導(dao)致(zhi)齒(chi)(chi)輪(lun)和(he)(he)軸(zhou)(zhou)承(cheng)(cheng)潤滑(hua)不(bu)(bu)良，影響齒(chi)(chi)輪(lun)和(he)(he)軸(zhou)(zhou)承(cheng)(cheng)壽命，嚴(yan)重時造成齒(chi)(chi)輪(lun)和(he)(he)軸(zhou)(zhou)承(cheng)(cheng)的報廢，加(jia)(jia)之(zhi)用(yong)(yong)戶在(zai)(zai)使(shi)用(yong)(yong)過(guo)(guo)程(cheng)中又不(bu)(bu)定(ding)經常查看和(he)(he)補充油(you)(you)(you)(you)。所(suo)以齒(chi)(chi)輪(lun)減(jian)速機(ji)潤滑(hua)油(you)(you)(you)(you)少(shao)，雖然(ran)不(bu)(bu)會(hui)出(chu)現(xian)通(tong)氣(qi)帽(mao)(mao)溢(yi)油(you)(you)(you)(you)現(xian)象(xiang)(xiang)，但存在(zai)(zai)的潛在(zai)(zai)風(feng)險(xian)遠大(da)于適當的加(jia)(jia)油(you)(you)(you)(you)過(guo)(guo)量。加(jia)(jia)油(you)(you)(you)(you)適當過(guo)(guo)量就(jiu)會(hui)加(jia)(jia)大(da)了通(tong)氣(qi)帽(mao)(mao)溢(yi)油(you)(you)(you)(you)以及密封部位漏(lou)油(you)(you)(you)(you)的風(feng)險(xian)，增加(jia)(jia)了齒(chi)(chi)輪(lun)減(jian)速機(ji)內部齒(chi)(chi)輪(lun)的攪油(you)(you)(you)(you)能(neng)(neng)量損(sun)失，降低(di)了齒(chi)(chi)輪(lun)減(jian)速機(ji)的效率，但不(bu)(bu)會(hui)出(chu)現(xian)齒(chi)(chi)輪(lun)和(he)(he)軸(zhou)(zhou)承(cheng)(cheng)報廢的嚴(yan)重后果。為避(bi)免加(jia)(jia)油(you)(you)(you)(you)過(guo)(guo)少(shao)造成齒(chi)(chi)輪(lun)和(he)(he)軸(zhou)(zhou)承(cheng)(cheng)報廢，用(yong)(yong)戶在(zai)(zai)適當多加(jia)(jia)油(you)(you)(you)(you)的情(qing)況(kuang)下(xia)，仍能(neng)(neng)避(bi)免減(jian)速機(ji)通(tong)氣(qi)帽(mao)(mao)溢(yi)油(you)(you)(you)(you)，降低(di)油(you)(you)(you)(you)流的速度和(he)(he)流量，需在(zai)(zai)原來結構(gou)基礎上再(zai)增加(jia)(jia)個(ge)擋油(you)(you)(you)(you)板(ban)，相當于建(jian)立兩道防止油(you)(you)(you)(you)流的堤(di)壩。新(xin)結構(gou)完成后繼續試驗(yan)(yan)觀察，將(jiang)潤滑(hua)油(you)(you)(you)(you)多加(jia)(jia)正常值(zhi)的1/3繼續試驗(yan)(yan)，齒(chi)(chi)輪(lun)減(jian)速機(ji)正反向(xiang)各運(yun)轉3小時，沒有(you)(you)出(chu)現(xian)通(tong)氣(qi)帽(mao)(mao)溢(yi)油(you)(you)(you)(you)現(xian)象(xiang)(xiang)。齒(chi)(chi)輪(lun)減(jian)速機(ji)通(tong)氣(qi)帽(mao)(mao)結構(gou)調整后，沒有(you)(you)發現(xian)齒(chi)(chi)輪(lun)減(jian)速機(ji)在(zai)(zai)使(shi)用(yong)(yong)過(guo)(guo)程(cheng)中出(chu)現(xian)通(tong)氣(qi)帽(mao)(mao)有(you)(you)溢(yi)油(you)(you)(you)(you)情(qing)況(kuang)。
