蝸(gua)輪蝸(gua)桿減(jian)(jian)速(su)(su)機(ji)(ji)軸端(duan)裝(zhuang)置的(de)改進。蝸(gua)輪蝸(gua)桿減(jian)(jian)速(su)(su)機(ji)(ji)是(shi)種具有結構(gou)緊(jin)湊，傳動比大，并且在定條件(jian)下(xia)具有自鎖功能的(de)傳動機(ji)(ji)械，是(shi)常見的(de)RV減(jian)(jian)速(su)(su)機(ji)(ji)之(zhi)，而且安裝(zhuang)方便，結構(gou)合理，越(yue)來越(yue)得到客戶的(de)青睞(lai)。與常用的(de)RV減(jian)(jian)速(su)(su)機(ji)(ji)樣，蝸(gua)輪蝸(gua)桿減(jian)(jian)速(su)(su)機(ji)(ji)也存在漏(lou)油、軸承、軸瓦損壞等問題。

蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)蝸(gua)(gua)(gua)(gua)桿減(jian)(jian)速(su)箱填(tian)料倉容積小，內部(bu)只裝(zhuang)填(tian)層25X25mm的(de)(de)(de)(de)油浸線盤根，因為油浸線盤要裝(zhuang)得(de)少，所以回彈(dan)性(xing)差，使(shi)(shi)用(yong)不長時(shi)(shi)(shi)間就會(hui)失去密封功(gong)能，導(dao)致潤滑油滲漏。日常運轉時(shi)(shi)(shi)，每(mei)天(tian)漏油量(liang)般在2-3千克(ke)左(zuo)右(you)，嚴重(zhong)時(shi)(shi)(shi)達到5千克(ke)之多，兩天(tian)就得(de)補次(ci)油料。另外，如果(guo)蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)蝸(gua)(gua)(gua)(gua)桿減(jian)(jian)速(su)機(ji)所處的(de)(de)(de)(de)環境溫度(du)(du)過(guo)(guo)(guo)高(gao)，夏(xia)季機(ji)體溫度(du)(du)達到80攝(she)氏度(du)(du)左(zuo)右(you)，超過(guo)(guo)(guo)了油浸線盤根的(de)(de)(de)(de)工作溫度(du)(du)，因此(ci)，盤根彈(dan)塑(su)性(xing)變形能力降低，使(shi)(shi)用(yong)壽命縮短，基本是1至(zhi)2個月更(geng)換次(ci)。由(you)于(yu)漏油較多較快，蝸(gua)(gua)(gua)(gua)桿腔(qiang)內的(de)(de)(de)(de)油位始終較低，蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)蝸(gua)(gua)(gua)(gua)桿間的(de)(de)(de)(de)潤滑效果(guo)較差，摩(mo)擦增大(da)，加重(zhong)了齒面(mian)(mian)(mian)的(de)(de)(de)(de)磨損程度(du)(du)，使(shi)(shi)RV減(jian)(jian)速(su)機(ji)齒面(mian)(mian)(mian)點(dian)蝕嚴重(zhong)。同(tong)時(shi)(shi)(shi)，也因為摩(mo)擦嚴重(zhong)產生(sheng)了過(guo)(guo)(guo)多的(de)(de)(de)(de)熱量(liang)，導(dao)致蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)蝸(gua)(gua)(gua)(gua)桿減(jian)(jian)速(su)機(ji)體溫度(du)(du)過(guo)(guo)(guo)高(gao)，使(shi)(shi)得(de)齒面(mian)(mian)(mian)間油膜(mo)過(guo)(guo)(guo)薄，進(jin)步惡化了其工作條件。由(you)于(yu)蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)、蝸(gua)(gua)(gua)(gua)桿齒面(mian)(mian)(mian)變壞(huai)，在RV減(jian)(jian)速(su)機(ji)運行(xing)時(shi)(shi)(shi)會(hui)產生(sheng)較大(da)的(de)(de)(de)(de)沖擊載荷，因此(ci)，軸瓦和軸承(cheng)易損壞(huai)。

改(gai)進(jin)方法：重(zhong)新制作(zuo)主動端(duan)端(duan)蓋，內徑尺寸(cun)為直徑為115毫(hao)米，摒棄油(you)(you)浸(jin)線盤(pan)根，采用(yong)(yong)(yong)(yong)了4套骨(gu)架式(shi)(shi)(shi)橡膠(jiao)油(you)(you)封(feng)(feng)(feng)，因為骨(gu)架式(shi)(shi)(shi)橡膠(jiao)油(you)(you)封(feng)(feng)(feng)的(de)工(gong)作(zuo)溫度(du)是(shi)110-130攝氏(shi)度(du)，回彈性(xing)(xing)較好，并且可(ke)又承(cheng)受較大(da)的(de)摩擦扭矩，因此(ci)，骨(gu)架式(shi)(shi)(shi)油(you)(you)封(feng)(feng)(feng)從耐用(yong)(yong)(yong)(yong)性(xing)(xing)、密封(feng)(feng)(feng)性(xing)(xing)等(deng)方面均優于油(you)(you)浸(jin)線盤(pan)根。更換(huan)RV減(jian)(jian)(jian)速(su)器蝸桿被動端(duan)止(zhi)(zhi)推(tui)軸(zhou)承(cheng)，用(yong)(yong)(yong)(yong)48324軸(zhou)承(cheng)取代原來8324軸(zhou)承(cheng)，這樣可(ke)以有(you)效(xiao)克服軸(zhou)向力(li)，防止(zhi)(zhi)RV減(jian)(jian)(jian)速(su)機(ji)(ji)蝸桿竄(cuan)動，提高軸(zhou)承(cheng)的(de)使用(yong)(yong)(yong)(yong)壽(shou)命，減(jian)(jian)(jian)輕(qing)了維護的(de)工(gong)作(zuo)量。當環(huan)境溫度(du)過高時，尤(you)其是(shi)在炎熱的(de)夏季，在斜齒輪減(jian)(jian)(jian)速(su)機(ji)(ji)旁(pang)設(she)置1-2臺軸(zhou)流風機(ji)(ji)對其進(jin)行(xing)降溫。潤(run)滑油(you)(you)中(zhong)可(ke)適量加(jia)入(ru)抗磨(mo)節能劑(ji)，在齒面形成牢固、柔韌的(de)保護膜，從而可(ke)以減(jian)(jian)(jian)輕(qing)摩擦。有(you)客戶反映(ying)，改(gai)進(jin)后(hou)，RV減(jian)(jian)(jian)速(su)機(ji)(ji)蝸桿兩端(duan)的(de)漏油(you)(you)問題得到了有(you)效(xiao)控(kong)制，基本上3個月補次(ci)油(you)(you)料就可(ke)以。由(you)于骨(gu)架式(shi)(shi)(shi)橡膠(jiao)油(you)(you)封(feng)(feng)(feng)耐用(yong)(yong)(yong)(yong)性(xing)(xing)好，使用(yong)(yong)(yong)(yong)壽(shou)命長，1-2年換(huan)次(ci)。蝸輪蝸桿減(jian)(jian)(jian)速(su)機(ji)(ji)運行(xing)平(ping)穩，軸(zhou)承(cheng)和軸(zhou)瓦的(de)使用(yong)(yong)(yong)(yong)壽(shou)命都(dou)得到了延長
