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(jie)構緊湊，傳遞扭矩大，使用壽命長(chang)，免維護，耐(nai)高(gao)溫，耐(nai)酸堿防(fang)腐蝕，適用于高(gao)溫高(gao)速(su)及有腐蝕工況環境的軸系傳動(dong)。

膜(mo)片型(xing)聯(lian)軸(zhou)(zhou)器能補償(chang)主動機(ji)(ji)與從動機(ji)(ji)之間由于(yu)制造誤(wu)差、安裝誤(wu)差、承載變形以及(ji)溫升變化的影響(xiang)等所引起的軸(zhou)(zhou)向(xiang)(xiang)、徑(jing)向(xiang)(xiang)和角向(xiang)(xiang)偏移。膜(mo)片彈(dan)性(xing)聯(lian)軸(zhou)(zhou)器屬金屬彈(dan)性(xing)元件撓性(xing)聯(lian)軸(zhou)(zhou)器，其依靠金屬聯(lian)軸(zhou)(zhou)器膜(mo)片來(lai)聯(lian)接主、從動機(ji)(ji)傳(chuan)遞(di)扭矩，具有彈(dan)性(xing)減振、無噪聲、不需潤滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)(qi)至少由一(yi)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和(he)兩(liang)個(ge)軸(zhou)(zhou)套組成(cheng)。膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被用銷釘(ding)緊(jin)固在(zai)軸(zhou)(zhou)套上一(yi)般(ban)不(bu)(bu)會(hui)松動或引起膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和(he)軸(zhou)(zhou)套之間的(de)反沖。有(you)一(yi)些生(sheng)產商(shang)提供(gong)兩(liang)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，也有(you)提供(gong)三(san)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，中間有(you)一(yi)個(ge)或兩(liang)個(ge)剛性元件(jian)，兩(liang)邊 再連(lian)在(zai)軸(zhou)(zhou)套上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)(qi)和(he)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)(qi)的(de)不(bu)(bu)同(tong)(tong)(tong)之處是(shi)處理(li)各(ge)種偏(pian)差(cha)能(neng)力的(de)不(bu)(bu)同(tong)(tong)(tong)，鑒(jian)于其(qi)需要(yao)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能(neng)復雜的(de)彎(wan)曲，所以(yi)單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)(qi)不(bu)(bu)太適應偏(pian)心。而(er)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)(qi)可(ke)以(yi)同(tong)(tong)(tong)時曲向(xiang)不(bu)(bu)同(tong)(tong)(tong)的(de)方向(xiang)，以(yi)此(ci)來補償偏(pian)心。
