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(chuan)遞扭矩(ju)大(da)，使用壽(shou)命長(chang)，免維護，耐高溫(wen)，耐酸堿防(fang)腐蝕，適用于高溫(wen)高速及有腐蝕工況(kuang)環(huan)境的軸系(xi)傳(chuan)動(dong)。

膜片(pian)型聯軸(zhou)(zhou)器(qi)能(neng)補償主動機與從(cong)動機之間由于制造誤差、安裝誤差、承載變形以及溫升變化(hua)的(de)(de)影(ying)響等所(suo)引(yin)起的(de)(de)軸(zhou)(zhou)向、徑向和角向偏移。膜片(pian)彈(dan)(dan)性(xing)聯軸(zhou)(zhou)器(qi)屬(shu)金(jin)屬(shu)彈(dan)(dan)性(xing)元件撓性(xing)聯軸(zhou)(zhou)器(qi)，其依靠(kao)金(jin)屬(shu)聯軸(zhou)(zhou)器(qi)膜片(pian)來(lai)聯接主、從(cong)動機傳(chuan)遞扭矩，具有彈(dan)(dan)性(xing)減振、無(wu)噪聲、不需潤滑的(de)(de)優點。

膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)至少由(you)一(yi)個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)和(he)兩(liang)個(ge)(ge)軸(zhou)(zhou)套(tao)組成。膜(mo)片(pian)(pian)(pian)(pian)被(bei)用銷(xiao)釘緊固在軸(zhou)(zhou)套(tao)上一(yi)般不會(hui)松動或引起膜(mo)片(pian)(pian)(pian)(pian)和(he)軸(zhou)(zhou)套(tao)之(zhi)間的(de)反(fan)沖。有一(yi)些(xie)生產商提(ti)供兩(liang)個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的(de)，也有提(ti)供三個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的(de)，中間有一(yi)個(ge)(ge)或兩(liang)個(ge)(ge)剛性元件，兩(liang)邊 再連在軸(zhou)(zhou)套(tao)上。單(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)和(he)雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)的(de)不同(tong)之(zhi)處(chu)是處(chu)理(li)各種偏(pian)差能(neng)力的(de)不同(tong)，鑒于其需要膜(mo)片(pian)(pian)(pian)(pian)能(neng)復(fu)雜的(de)彎曲，所以單(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)不太適應偏(pian)心。而雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)可以同(tong)時曲向不同(tong)的(de)方向，以此(ci)來補(bu)償偏(pian)心。
