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(da)，使用(yong)(yong)壽命長，免(mian)維護，耐高(gao)溫(wen)，耐酸堿防腐蝕，適用(yong)(yong)于高(gao)溫(wen)高(gao)速及有腐蝕工況環境的(de)軸系傳動。

膜片型聯軸器(qi)(qi)(qi)能補償主(zhu)動(dong)機與從(cong)動(dong)機之間由(you)于制造誤(wu)差、安裝誤(wu)差、承載變形以及溫升變化的影(ying)響等所引起的軸向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片彈(dan)性(xing)聯軸器(qi)(qi)(qi)屬金屬彈(dan)性(xing)元件撓性(xing)聯軸器(qi)(qi)(qi)，其依(yi)靠金屬聯軸器(qi)(qi)(qi)膜片來聯接主(zhu)、從(cong)動(dong)機傳遞扭矩(ju)，具(ju)有彈(dan)性(xing)減(jian)振、無噪聲、不需潤滑的優點。

膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器至少由一(yi)個(ge)(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)和(he)兩個(ge)(ge)(ge)軸(zhou)(zhou)套(tao)組成。膜(mo)片(pian)(pian)(pian)(pian)被用銷(xiao)釘緊(jin)固(gu)在軸(zhou)(zhou)套(tao)上一(yi)般不(bu)會(hui)松動(dong)或引起膜(mo)片(pian)(pian)(pian)(pian)和(he)軸(zhou)(zhou)套(tao)之間的(de)(de)(de)反沖。有(you)一(yi)些生產商提(ti)供兩個(ge)(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)，也有(you)提(ti)供三(san)個(ge)(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)，中間有(you)一(yi)個(ge)(ge)(ge)或兩個(ge)(ge)(ge)剛性(xing)元(yuan)件，兩邊 再連(lian)在軸(zhou)(zhou)套(tao)上。單(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器和(he)雙膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器的(de)(de)(de)不(bu)同(tong)(tong)之處(chu)是處(chu)理各種偏(pian)差能(neng)力的(de)(de)(de)不(bu)同(tong)(tong)，鑒于其需要膜(mo)片(pian)(pian)(pian)(pian)能(neng)復雜的(de)(de)(de)彎曲(qu)，所以(yi)單(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器不(bu)太適應(ying)偏(pian)心。而雙膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器可(ke)以(yi)同(tong)(tong)時曲(qu)向(xiang)(xiang)不(bu)同(tong)(tong)的(de)(de)(de)方向(xiang)(xiang)，以(yi)此來補償(chang)偏(pian)心。
