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湊，傳(chuan)遞扭矩(ju)大，使用壽命(ming)長，免維護，耐高溫，耐酸(suan)堿防腐(fu)蝕，適用于高溫高速(su)及有(you)腐(fu)蝕工況(kuang)環境的軸系(xi)傳(chuan)動。

膜(mo)(mo)片(pian)型(xing)聯軸(zhou)(zhou)器(qi)(qi)能(neng)補償主動(dong)(dong)機(ji)與從動(dong)(dong)機(ji)之間由于制(zhi)造誤差、安裝誤差、承載(zai)變形以及溫升變化(hua)的影響等所引起的軸(zhou)(zhou)向(xiang)(xiang)、徑向(xiang)(xiang)和(he)角向(xiang)(xiang)偏移。膜(mo)(mo)片(pian)彈(dan)(dan)性聯軸(zhou)(zhou)器(qi)(qi)屬金屬彈(dan)(dan)性元件撓(nao)性聯軸(zhou)(zhou)器(qi)(qi)，其(qi)依靠金屬聯軸(zhou)(zhou)器(qi)(qi)膜(mo)(mo)片(pian)來(lai)聯接主、從動(dong)(dong)機(ji)傳(chuan)遞扭矩，具(ju)有彈(dan)(dan)性減振、無噪(zao)聲、不需潤滑的優(you)點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器至(zhi)少由一(yi)個(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和兩個(ge)(ge)(ge)軸(zhou)(zhou)套組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被用銷(xiao)釘緊(jin)固在軸(zhou)(zhou)套上一(yi)般不(bu)會(hui)松動或引(yin)起膜(mo)(mo)片(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套之間的反沖。有一(yi)些生產(chan)商提供(gong)兩個(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的，也(ye)有提供(gong)三個(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的，中間有一(yi)個(ge)(ge)(ge)或兩個(ge)(ge)(ge)剛(gang)性元件，兩邊 再連在軸(zhou)(zhou)套上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器和雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器的不(bu)同(tong)之處(chu)是(shi)處(chu)理(li)各(ge)種偏(pian)差能(neng)力的不(bu)同(tong)，鑒于其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)能(neng)復雜的彎曲(qu)(qu)，所(suo)以單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器不(bu)太適(shi)應偏(pian)心(xin)。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器可以同(tong)時(shi)曲(qu)(qu)向不(bu)同(tong)的方向，以此來補(bu)償偏(pian)心(xin)。
