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(di)扭矩大(da)，使用壽命長，免(mian)維(wei)護，耐(nai)高溫(wen)(wen)，耐(nai)酸堿防腐蝕，適用于(yu)高溫(wen)(wen)高速(su)及有腐蝕工況(kuang)環境的(de)軸(zhou)系傳動。

膜片(pian)(pian)(pian)型聯(lian)軸器能(neng)補償主動機與從動機之間由于制造誤(wu)差(cha)、安(an)裝誤(wu)差(cha)、承載變形以及溫升變化的(de)影響等所引起的(de)軸向、徑向和角向偏(pian)移。膜片(pian)(pian)(pian)彈性聯(lian)軸器屬金(jin)屬彈性元件撓性聯(lian)軸器，其依(yi)靠金(jin)屬聯(lian)軸器膜片(pian)(pian)(pian)來聯(lian)接主、從動機傳遞扭矩，具有彈性減振、無噪聲、不需潤滑的(de)優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)(qi)至少由一(yi)個(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)(he)兩個(ge)(ge)(ge)軸(zhou)套(tao)(tao)(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被用銷釘緊固在(zai)軸(zhou)套(tao)(tao)(tao)上一(yi)般不(bu)會松動或引起(qi)膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)(he)軸(zhou)套(tao)(tao)(tao)之間的(de)反沖。有一(yi)些生產(chan)商提供兩個(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，也有提供三(san)個(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，中間有一(yi)個(ge)(ge)(ge)或兩個(ge)(ge)(ge)剛性元(yuan)件，兩邊 再連在(zai)軸(zhou)套(tao)(tao)(tao)上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)(qi)和(he)(he)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)(qi)的(de)不(bu)同(tong)(tong)之處(chu)是處(chu)理各種偏(pian)差能(neng)力的(de)不(bu)同(tong)(tong)，鑒于其需要膜(mo)(mo)片(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)聯軸(zhou)器(qi)(qi)(qi)不(bu)太適應偏(pian)心。而(er)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)(qi)可以(yi)同(tong)(tong)時曲向(xiang)不(bu)同(tong)(tong)的(de)方向(xiang)，以(yi)此來補償偏(pian)心。
