鵠興NMRV蝸輪蝸桿減速機選型

原鑿井絞(jiao)車采用(yong)(yong)球面(mian)(mian)(mian)蝸(gua)(gua)(gua)輪(lun)(lun)蝸(gua)(gua)(gua)桿(gan)(gan)(gan)(gan)(gan)減速(su)(su)箱為第(di)傳動，設(she)計選型是(shi)(shi)正(zheng)確的(de)，由于受球面(mian)(mian)(mian)蝸(gua)(gua)(gua)輪(lun)(lun)蝸(gua)(gua)(gua)桿(gan)(gan)(gan)(gan)(gan)加(jia)工(gong)(gong)(gong)(gong)技術的(de)限制，目前(qian)還(huan)加(jia)工(gong)(gong)(gong)(gong)不(bu)出合(he)乎設(she)計要求(qiu)的(de)的(de)，影響了使用(yong)(yong)。目前(qian)，內球面(mian)(mian)(mian)蝸(gua)(gua)(gua)桿(gan)(gan)(gan)(gan)(gan)加(jia)工(gong)(gong)(gong)(gong)主要采用(yong)(yong)移(yi)位倒坡和(he)(he)對稱修(xiu)(xiu)型的(de)工(gong)(gong)(gong)(gong)藝方法，加(jia)工(gong)(gong)(gong)(gong)不(bu)出全修(xiu)(xiu)形蝸(gua)(gua)(gua)桿(gan)(gan)(gan)(gan)(gan)，同時(shi)，RV減速(su)(su)機(ji)(ji)蝸(gua)(gua)(gua)輪(lun)(lun)的(de)齒形采用(yong)(yong)軸向雙飛刀加(jia)工(gong)(gong)(gong)(gong)，形成不(bu)了凹(ao)面(mian)(mian)(mian)精確齒形，蝸(gua)(gua)(gua)桿(gan)(gan)(gan)(gan)(gan)和(he)(he)蝸(gua)(gua)(gua)輪(lun)(lun)跌倒時(shi)不(bu)易(yi)貼合(he)，達(da)不(bu)到理想共(gong)軛，裝配(pei)時(shi)鉗(qian)工(gong)(gong)(gong)(gong)修(xiu)(xiu)刮量大，調(diao)試和(he)(he)跑合(he)時(shi)間(jian)長，既(ji)花費勞(lao)力，又浪費工(gong)(gong)(gong)(gong)時(shi)。另外，這種蝸(gua)(gua)(gua)輪(lun)(lun)蝸(gua)(gua)(gua)桿(gan)(gan)(gan)(gan)(gan)減速(su)(su)機(ji)(ji)的(de)蝸(gua)(gua)(gua)桿(gan)(gan)(gan)(gan)(gan)多數是(shi)(shi)做成調(diao)質的(de)軟齒面(mian)(mian)(mian)，蝸(gua)(gua)(gua)桿(gan)(gan)(gan)(gan)(gan)齒面(mian)(mian)(mian)光潔度低、致使絞(jiao)車在(zai)運轉過程(cheng)中(zhong)(zhong)齒面(mian)(mian)(mian)容易(yi)膠合(he)，造成停工(gong)(gong)(gong)(gong)事故。上述情況表明，選用(yong)(yong)球面(mian)(mian)(mian)RV減速(su)(su)機(ji)(ji)作(zuo)為第(di)傳動，其(qi)球面(mian)(mian)(mian)蝸(gua)(gua)(gua)輪(lun)(lun)蝸(gua)(gua)(gua)桿(gan)(gan)(gan)(gan)(gan)的(de)加(jia)工(gong)(gong)(gong)(gong)已(yi)經成為各制造廠(chang)家在(zai)絞(jiao)車生產(chan)中(zhong)(zhong)不(bu)易(yi)解(jie)決的(de)個(ge)重(zhong)要關鍵(jian)和(he)(he)難題，它是(shi)(shi)影響絞(jiao)車質量的(de)主要方面(mian)(mian)(mian)。

新絞車采用(yong)了環面(mian)蝸(gua)(gua)(gua)(gua)(gua)桿(gan)傳(chuan)動(dong)(dong)——平面(mian)二(er)(er)次包(bao)絡環面(mian)蝸(gua)(gua)(gua)(gua)(gua)桿(gan)傳(chuan)動(dong)(dong)。在設計(ji)RV減(jian)速機的蝸(gua)(gua)(gua)(gua)(gua)桿(gan)和(he)蝸(gua)(gua)(gua)(gua)(gua)輪(lun)(lun)齒(chi)形(xing)部(bu)分時(shi)，有意保留了原球副的基本參數，按“二(er)(er)包(bao)”進(jin)行(xing)佳參數選(xuan)擇和(he)比較，以8o、8o30’、 9o 、9o30’ 、10o五種不同(tong)的角度進(jin)行(xing)了嚙合性(xing)(xing)(xing)(xing)能(neng)計(ji)算和(he)分析，從嚙合性(xing)(xing)(xing)(xing)能(neng)好(hao)和(he)工(gong)藝性(xing)(xing)(xing)(xing)能(neng)好(hao)兩大指標進(jin)行(xing)優(you)選(xuan)，后(hou)確(que)定選(xuan)取砂輪(lun)(lun)傾角等(deng)于8o30’的典型傳(chuan)動(dong)(dong)。RV減(jian)速器的蝸(gua)(gua)(gua)(gua)(gua)桿(gan)材質用(yong)40Cr, 蝸(gua)(gua)(gua)(gua)(gua)桿(gan)粗車齒(chi)溝(gou)后(hou)調質HB229-269。蝸(gua)(gua)(gua)(gua)(gua)桿(gan)齒(chi)面(mian)高(gao)頻(pin)淬火，齒(chi)面(mian)硬度可達RC55-60, 深度為(wei)0.5-2毫米，精(jing)磨蝸(gua)(gua)(gua)(gua)(gua)桿(gan)齒(chi)形(xing)。蝸(gua)(gua)(gua)(gua)(gua)輪(lun)(lun)蝸(gua)(gua)(gua)(gua)(gua)桿(gan)減(jian)速機中蝸(gua)(gua)(gua)(gua)(gua)輪(lun)(lun)材質原來采用(yong)無錫青銅(tong)，更改為(wei)新材料(liao)重稀土銅(tong)合金。該材料(liao)具有高(gao)強度，又(you)有良好(hao)的延伸率和(he)沖(chong)擊值，并且有熱變形(xing)小，切削(xue)性(xing)(xing)(xing)(xing)能(neng)好(hao)的優(you)點。RV減(jian)速機蝸(gua)(gua)(gua)(gua)(gua)輪(lun)(lun)的加(jia)工(gong)用(yong)新型單(dan)線布齒(chi)蝸(gua)(gua)(gua)(gua)(gua)輪(lun)(lun)滾刀，切出(chu)的蝸(gua)(gua)(gua)(gua)(gua)輪(lun)(lun)齒(chi)面(mian)殘留金屬少，制造精(jing)度高(gao)。

上(shang)述(shu)過(guo)程(cheng)做完后(hou)的(de)(de)(de)(de)綜(zong)合(he)(he)(he)優(you)點是，使(shi)蝸(gua)(gua)輪(lun)蝸(gua)(gua)桿伺(si)服減(jian)速機既能保證嚙(nie)合(he)(he)(he)性能好(hao)，又有(you)良好(hao)的(de)(de)(de)(de)工(gong)(gong)(gong)藝(yi)性，即在設(she)計(ji)時就將蝸(gua)(gua)輪(lun)蝸(gua)(gua)桿的(de)(de)(de)(de)嚙(nie)合(he)(he)(he)性能結合(he)(he)(he)工(gong)(gong)(gong)藝(yi)條件(jian)作(zuo)了(le)佳參(can)數選擇(ze)，其結果(guo)所(suo)得參(can)數必然是佳的(de)(de)(de)(de)，所(suo)要求的(de)(de)(de)(de)加工(gong)(gong)(gong)手段也是可行(xing)的(de)(de)(de)(de)。所(suo)以，按我(wo)們設(she)計(ji)、制(zhi)造的(de)(de)(de)(de)平(ping)面(mian)二次(ci)包(bao)絡環面(mian)蝸(gua)(gua)桿副(fu)，在跑合(he)(he)(he)過(guo)程(cheng)中，很容易接理論(lun)嚙(nie)合(he)(he)(he)區貼合(he)(he)(he)，共(gong)軛狀態(tai)較為理想，承載(zai)能力高(gao)。

該鑿井絞(jiao)車RV減速機設計(ji)合理，經久耐用(yong)，運(yun)轉(zhuan)噪聲小，維護方便(bian)，長期以(yi)(yi)來沒有(you)出現過(guo)故障(zhang)，是很理想(xiang)和受(shou)歡迎(ying)的機構(gou)，所(suo)以(yi)(yi)，對較車作改型設計(ji)，具有(you)重大的技(ji)術效果(guo)和經濟價值。
