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(gou)緊湊，傳(chuan)遞扭矩大，使用(yong)壽命(ming)長，免維護，耐(nai)高溫，耐(nai)酸堿(jian)防(fang)腐(fu)蝕，適用(yong)于高溫高速及(ji)有腐(fu)蝕工況環(huan)境的(de)軸(zhou)系傳(chuan)動。

膜片(pian)型(xing)聯(lian)(lian)(lian)軸(zhou)器(qi)能補償主動(dong)機(ji)(ji)與從動(dong)機(ji)(ji)之間由于制造(zao)誤(wu)差(cha)、安裝誤(wu)差(cha)、承載變形以及(ji)溫升變化的(de)影(ying)響(xiang)等所引起(qi)的(de)軸(zhou)向、徑(jing)向和角向偏移。膜片(pian)彈(dan)性聯(lian)(lian)(lian)軸(zhou)器(qi)屬(shu)金屬(shu)彈(dan)性元件撓性聯(lian)(lian)(lian)軸(zhou)器(qi)，其依靠金屬(shu)聯(lian)(lian)(lian)軸(zhou)器(qi)膜片(pian)來(lai)聯(lian)(lian)(lian)接主、從動(dong)機(ji)(ji)傳遞(di)扭矩，具有彈(dan)性減振、無噪(zao)聲、不需潤滑的(de)優點(dian)。

膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)至少由一(yi)個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)和(he)(he)兩(liang)個(ge)(ge)軸(zhou)(zhou)套(tao)組(zu)成。膜(mo)(mo)(mo)片(pian)(pian)(pian)被(bei)用(yong)銷釘緊固(gu)在(zai)軸(zhou)(zhou)套(tao)上一(yi)般不(bu)(bu)會(hui)松動(dong)或引起膜(mo)(mo)(mo)片(pian)(pian)(pian)和(he)(he)軸(zhou)(zhou)套(tao)之間(jian)(jian)的(de)(de)反(fan)沖。有(you)(you)(you)一(yi)些生產商提供兩(liang)個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)的(de)(de)，也(ye)有(you)(you)(you)提供三個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)的(de)(de)，中間(jian)(jian)有(you)(you)(you)一(yi)個(ge)(ge)或兩(liang)個(ge)(ge)剛性元(yuan)件，兩(liang)邊 再(zai)連在(zai)軸(zhou)(zhou)套(tao)上。單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)和(he)(he)雙膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)的(de)(de)不(bu)(bu)同(tong)(tong)之處是(shi)處理各種偏差能(neng)力(li)的(de)(de)不(bu)(bu)同(tong)(tong)，鑒于其需要(yao)膜(mo)(mo)(mo)片(pian)(pian)(pian)能(neng)復雜的(de)(de)彎(wan)曲，所(suo)以(yi)單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)不(bu)(bu)太適應偏心。而(er)雙膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)可以(yi)同(tong)(tong)時(shi)曲向不(bu)(bu)同(tong)(tong)的(de)(de)方向，以(yi)此來補償偏心。
