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，傳遞扭矩大，使(shi)用(yong)壽命(ming)長，免維護，耐高溫，耐酸堿防腐(fu)蝕，適用(yong)于高溫高速及有腐(fu)蝕工況環境的軸系傳動。

膜(mo)片(pian)型聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)能補償主(zhu)動(dong)(dong)機與從動(dong)(dong)機之間(jian)由于制(zhi)造誤差(cha)、安(an)裝誤差(cha)、承載變形以及溫升變化的(de)影(ying)響等所引起(qi)的(de)軸(zhou)向(xiang)、徑向(xiang)和(he)角(jiao)向(xiang)偏(pian)移(yi)。膜(mo)片(pian)彈(dan)性(xing)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)屬金(jin)屬彈(dan)性(xing)元件撓性(xing)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)，其依靠金(jin)屬聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)膜(mo)片(pian)來聯(lian)(lian)(lian)接主(zhu)、從動(dong)(dong)機傳遞扭矩，具有(you)彈(dan)性(xing)減(jian)振、無噪聲、不(bu)需(xu)潤滑的(de)優點(dian)。

膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)(zhou)器至少(shao)由一個(ge)(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)和兩(liang)個(ge)(ge)(ge)軸(zhou)(zhou)(zhou)套組成。膜(mo)(mo)(mo)片(pian)(pian)(pian)被用銷釘緊(jin)固在軸(zhou)(zhou)(zhou)套上一般不(bu)會松動(dong)或引起膜(mo)(mo)(mo)片(pian)(pian)(pian)和軸(zhou)(zhou)(zhou)套之(zhi)間的(de)反沖(chong)。有一些生產商提供兩(liang)個(ge)(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)的(de)，也有提供三個(ge)(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)的(de)，中(zhong)間有一個(ge)(ge)(ge)或兩(liang)個(ge)(ge)(ge)剛性元件，兩(liang)邊(bian) 再連在軸(zhou)(zhou)(zhou)套上。單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)(zhou)器和雙膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)(zhou)器的(de)不(bu)同(tong)(tong)之(zhi)處是處理各種偏(pian)(pian)差能(neng)力的(de)不(bu)同(tong)(tong)，鑒(jian)于(yu)其需要膜(mo)(mo)(mo)片(pian)(pian)(pian)能(neng)復雜(za)的(de)彎曲，所以單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)(zhou)器不(bu)太(tai)適應偏(pian)(pian)心。而雙膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)(zhou)器可以同(tong)(tong)時曲向不(bu)同(tong)(tong)的(de)方向，以此來(lai)補(bu)償(chang)偏(pian)(pian)心。
