改進(jin)措施(shi)：為(wei)(wei)了確保RV減(jian)(jian)速箱(xiang)正常運行，根據(ju)其結構(gou),決(jue)定(ding)(ding)重(zhong)新(xin)(xin)加(jia)工(gong)蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)軸(zhou),并把蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)軸(zhou)下(xia)(xia)端加(jia)長,其余尺寸不變,同時增(zeng)(zeng)(zeng)加(jia)個軸(zhou)承(cheng)底(di)(di)座,固定(ding)(ding)到蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)蝸(gua)(gua)(gua)(gua)桿(gan)減(jian)(jian)速機(ji)底(di)(di)部(bu)。蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)軸(zhou)材質選(xuan)用(yong)40Cr，調質處理(li)后(hou)HB值為(wei)(wei)250-280。根據(ju)箱(xiang)體(ti)實際尺寸,新(xin)(xin)加(jia)工(gong)的(de)蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)軸(zhou)長度在(zai)原(yuan)來軸(zhou)的(de)下(xia)(xia)部(bu)增(zeng)(zeng)(zeng)加(jia)40mm，并把加(jia)長后(hou)的(de)蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)軸(zhou)和(he)新(xin)(xin)增(zeng)(zeng)(zeng)軸(zhou)承(cheng)座起與RV減(jian)(jian)速機(ji)箱(xiang)體(ti)上殼(ke)(ke)體(ti)整(zheng)體(ti)裝配好，以(yi)其下(xia)(xia)殼(ke)(ke)體(ti)結合面(mian)為(wei)(wei)基(ji)(ji)準(zhun)，并將蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)蝸(gua)(gua)(gua)(gua)桿(gan)減(jian)(jian)速機(ji)箱(xiang)體(ti)下(xia)(xia)殼(ke)(ke)體(ti)內(nei)(nei)(nei)底(di)(di)面(mian)的(de)有效安裝面(mian)加(jia)工(gong)成平面(mian)。以(yi)上蓋(gai)軸(zhou)承(cheng)孔(kong)中(zhong)心線為(wei)(wei)基(ji)(ji)準(zhun),把RV伺服減(jian)(jian)速機(ji)的(de)上殼(ke)(ke)體(ti)和(he)蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)軸(zhou)與下(xia)(xia)殼(ke)(ke)體(ti)整(zheng)體(ti)裝配固定(ding)(ding)。蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)蝸(gua)(gua)(gua)(gua)桿(gan)減(jian)(jian)速機(ji)的(de)下(xia)(xia)殼(ke)(ke)體(ti)與新(xin)(xin)增(zeng)(zeng)(zeng)軸(zhou)承(cheng)座用(yong)螺栓連(lian)接，將新(xin)(xin)增(zeng)(zeng)(zeng)軸(zhou)承(cheng)座固定(ding)(ding)在(zai)蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)蝸(gua)(gua)(gua)(gua)桿(gan)減(jian)(jian)速機(ji)的(de)內(nei)(nei)(nei)底(di)(di)面(mian)。RV減(jian)(jian)速機(ji)的(de)軸(zhou)承(cheng)座采用(yong)45鋼,淬火后(hou)HRC值為(wei)(wei)40,軸(zhou)承(cheng)內(nei)(nei)(nei)孔(kong)尺寸精(jing)度為(wei)(wei)0-0.02mm,內(nei)(nei)(nei)孔(kong)表面(mian)光(guang)潔度為(wei)(wei)8。需要注意(yi)的(de)是:由于新(xin)(xin)增(zeng)(zeng)(zeng)軸(zhou)承(cheng)座用(yong)螺栓固定(ding)(ding)在(zai)RV減(jian)(jian)速機(ji)箱(xiang)體(ti)的(de)內(nei)(nei)(nei)底(di)(di)面(mian)上,在(zai)安裝新(xin)(xin)增(zeng)(zeng)(zeng)軸(zhou)承(cheng)座時必須(xu)對螺栓及底(di)(di)部(bu)加(jia)工(gong)孔(kong)等(deng)處進(jin)行密(mi)封(feng)處理(li),以(yi)確保蝸(gua)(gua)(gua)(gua)輪(lun)(lun)(lun)(lun)蝸(gua)(gua)(gua)(gua)桿(gan)減(jian)(jian)速機(ji)在(zai)運行時不發生漏油。

改(gai)進后(hou)的(de)效果：改(gai)進后(hou)的(de)NMRV040減(jian)速機(ji)(ji)，在原來懸空的(de)蝸(gua)輪(lun)(lun)軸(zhou)底部增加(jia)了(le)個支(zhi)撐點，蝸(gua)輪(lun)(lun)軸(zhou)的(de)剛(gang)度大大增加(jia)，蝸(gua)輪(lun)(lun)副運行(xing)平穩，避免了(le)抖動，軸(zhou)承運行(xing)壽命(ming)大大提(ti)高，減(jian)少維(wei)(wei)修停機(ji)(ji)時(shi)(shi)間(jian)，提(ti)高了(le)生產效率，同時(shi)(shi)節約(yue)大量的(de)維(wei)(wei)修費用。
