膜片聯軸器在傳遞扭矩的同時通過彈性膜片的的變形來補償軸向和角向的位移，是一種高性能的金屬彈性撓性聯軸器。膜片式聯軸器結構緊(jin)湊，傳遞扭矩(ju)大，使用(yong)(yong)壽命長(chang)，免維護，耐高(gao)溫(wen)，耐酸堿防(fang)腐蝕，適用(yong)(yong)于高(gao)溫(wen)高(gao)速及有腐蝕工況環境的軸(zhou)系傳動。

膜片型聯(lian)(lian)(lian)(lian)軸器(qi)能補償(chang)主(zhu)動機(ji)與從(cong)動機(ji)之間由于制造誤差(cha)、安(an)裝誤差(cha)、承載變形以(yi)及(ji)溫(wen)升變化(hua)的影(ying)響等所引起的軸向(xiang)(xiang)、徑向(xiang)(xiang)和(he)角向(xiang)(xiang)偏(pian)移。膜片彈性聯(lian)(lian)(lian)(lian)軸器(qi)屬(shu)(shu)金屬(shu)(shu)彈性元件撓(nao)性聯(lian)(lian)(lian)(lian)軸器(qi)，其依靠金屬(shu)(shu)聯(lian)(lian)(lian)(lian)軸器(qi)膜片來聯(lian)(lian)(lian)(lian)接(jie)主(zhu)、從(cong)動機(ji)傳遞扭矩(ju)，具有彈性減振、無噪聲、不需潤滑(hua)的優點。

膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器至少由一(yi)個(ge)膜片(pian)(pian)(pian)(pian)和兩(liang)(liang)個(ge)軸套(tao)組(zu)成(cheng)。膜片(pian)(pian)(pian)(pian)被用(yong)銷釘緊固在(zai)軸套(tao)上(shang)(shang)一(yi)般不(bu)(bu)會松動或引起膜片(pian)(pian)(pian)(pian)和軸套(tao)之間的(de)反(fan)沖(chong)。有(you)一(yi)些生(sheng)產商提(ti)供(gong)兩(liang)(liang)個(ge)膜片(pian)(pian)(pian)(pian)的(de)，也有(you)提(ti)供(gong)三個(ge)膜片(pian)(pian)(pian)(pian)的(de)，中間有(you)一(yi)個(ge)或兩(liang)(liang)個(ge)剛性(xing)元(yuan)件，兩(liang)(liang)邊(bian) 再連在(zai)軸套(tao)上(shang)(shang)。單(dan)膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器和雙膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器的(de)不(bu)(bu)同之處是(shi)處理各種偏差能力的(de)不(bu)(bu)同，鑒于其需(xu)要膜片(pian)(pian)(pian)(pian)能復雜的(de)彎曲，所以單(dan)膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器不(bu)(bu)太適應偏心(xin)。而雙膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器可(ke)以同時曲向不(bu)(bu)同的(de)方向，以此來補償偏心(xin)。
