RV減速機和絲杠副組成的(de)傳動(dong)(dong)單元在各個行(xing)(xing)業應用(yong)廣泛。如機械行(xing)(xing)業的(de)傳動(dong)(dong)裝(zhuang)(zhuang)置、治金行(xing)(xing)業的(de)軋輥(gun)運動(dong)(dong)裝(zhuang)(zhuang)置、煉鋼廠鋼包提升(sheng)和翻轉裝(zhuang)(zhuang)置以及人不可(ke)及場所(suo)的(de)運動(dong)(dong)傳遞裝(zhuang)(zhuang)置；鐵(tie)路車(che)輛行(xing)(xing)業的(de)車(che)輛舉(ju)升(sheng)回，大(da)型(xing)柔性夾緊、轉位工(gong)裝(zhuang)(zhuang)、焊接(jie)機器人等；建(jian)筑行(xing)(xing)業的(de)舉(ju)升(sheng)裝(zhuang)(zhuang)置、大(da)型(xing)門窗自動(dong)(dong)或遙(yao)(yao)控(kong)開啟裝(zhuang)(zhuang)置；水利等行(xing)(xing)業用(yong)閘門的(de)開啟裝(zhuang)(zhuang)置、雷(lei)達及太陽能遙(yao)(yao)感裝(zhuang)(zhuang)置；醫療器械、升(sheng)降舞臺以及汽車(che)制造的(de)舉(ju)升(sheng)裝(zhuang)(zhuang)置等等。

工作原理(li)：升(sheng)降機構是用(yong)兩(liang)套蝸(gua)輪蝸(gua)桿NMRV150減(jian)速機和絲杠副(fu)組成(cheng)，通過傳動(dong)(dong)(dong)(dong)單元的(de)同(tong)步旋轉(zhuan)，使(shi)固(gu)定在(zai)升(sheng)降平臺(tai)(tai)上的(de)運動(dong)(dong)(dong)(dong)螺母沿(yan)絲杠作直線(xian)運動(dong)(dong)(dong)(dong)，帶(dai)動(dong)(dong)(dong)(dong)平臺(tai)(tai)升(sheng)降；輔以(yi)兩(liang)套導柱(zhu)以(yi)保證平臺(tai)(tai)運動(dong)(dong)(dong)(dong)的(de)平衡性，并在(zai)平臺(tai)(tai)上固(gu)定直線(xian)軸承以(yi)消除(chu)平臺(tai)(tai)給予導柱(zhu)的(de)徑向力及(ji)減(jian)小摩擦(ca)。由于(yu)它是用(yong)兩(liang)套傳動(dong)(dong)(dong)(dong)單元驅(qu)動(dong)(dong)(dong)(dong)同(tong)一(yi)平臺(tai)(tai)升(sheng)降，故(gu)將其(qi)稱為兩(liang)驅(qu)動(dong)(dong)(dong)(dong)升(sheng)降機構。

安全性(xing)設計：兩(liang)驅(qu)動(dong)(dong)升(sheng)(sheng)降機(ji)構(gou)的(de)(de)(de)(de)安全性(xing)主要從以下幾(ji)個方面(mian)考慮：在設計中，將RV減(jian)速機(ji)的(de)(de)(de)(de)蝸輪(lun)通過(guo)鍵與絲杠連(lian)接(jie)作同步轉動(dong)(dong)；在升(sheng)(sheng)降的(de)(de)(de)(de)高位(wei)(wei)和低(di)位(wei)(wei)各采(cai)(cai)用(yong)雙限(xian)位(wei)(wei)并聯實現升(sheng)(sheng)降機(ji)構(gou)的(de)(de)(de)(de)升(sheng)(sheng)降過(guo)程保護；在升(sheng)(sheng)降的(de)(de)(de)(de)高位(wei)(wei)和低(di)位(wei)(wei)各設置(zhi)兩(liang)套鎖緊位(wei)(wei)置(zhi)，利用(yong)蝸輪(lun)蝸桿減(jian)速器的(de)(de)(de)(de)自鎖性(xing)防止(zhi)絲杠的(de)(de)(de)(de)逆轉，以對絲杠進行(xing)保護和增加(jia)升(sheng)(sheng)降機(ji)構(gou)和艙體的(de)(de)(de)(de)連(lian)接(jie)剛性(xing)；在驅(qu)動(dong)(dong)電(dian)機(ji)輸出端加(jia)裝(zhuang)力(li)矩限(xian)制器，以防止(zhi)過(guo)載或傳(chuan)動(dong)(dong)鏈、絲杠出現卡滯；電(dian)氣控制系(xi)統采(cai)(cai)用(yong)線(xian)控方式，以便操作人員(yuan)在升(sheng)(sheng)降機(ji)構(gou)工作過(guo)程中能夠(gou)及時觀察設備出艙的(de)(de)(de)(de)情況。

注(zhu)意事項：以RV減速(su)機(ji)(ji)(ji)和(he)絲(si)杠(gang)副(fu)為(wei)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)元件(jian)的升降機(ji)(ji)(ji)構，必(bi)須注(zhu)意螺紋(wen)的長度，特(te)別對(dui)(dui)于垂直(zhi)安裝(zhuang)的絲(si)杠(gang)副(fu)，容易造成運動(dong)(dong)(dong)螺母(mu)越程(cheng)(cheng)。一(yi)般(ban)絲(si)杠(gang)螺紋(wen)設計長度為(wei)工作行(xing)程(cheng)(cheng)加上4-6倍的導程(cheng)(cheng)；盡量減少傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)鏈的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)部件(jian)和(he)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)距(ju)離(li)，以提高蝸輪蝸桿減速(su)機(ji)(ji)(ji)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)效率；傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)鏈布局合(he)理，明確各個絲(si)杠(gang)副(fu)的旋轉方向，避免RV減速(su)機(ji)(ji)(ji)或者絲(si)杠(gang)副(fu)承受過(guo)大的載荷。傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)鏈的對(dui)(dui)稱設計和(he)使(shi)用(yong)同一(yi)動(dong)(dong)(dong)力(li)裝(zhuang)置也(ye)使(shi)得各絲(si)杠(gang)副(fu)可獲(huo)得相同的轉速(su)，使(shi)平臺能夠穩定升降。
