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(cou)，傳(chuan)(chuan)遞扭矩大，使用壽命長，免維護(hu)，耐高溫，耐酸堿防腐蝕(shi)，適(shi)用于高溫高速及有腐蝕(shi)工況環(huan)境的軸系傳(chuan)(chuan)動。

膜片(pian)型聯(lian)軸器(qi)能補(bu)償主(zhu)動機(ji)(ji)與從動機(ji)(ji)之(zhi)間由(you)于(yu)制(zhi)造誤差、安裝誤差、承載變形以(yi)及溫(wen)升變化(hua)的影響等(deng)所引(yin)起的軸向、徑向和角向偏(pian)移。膜片(pian)彈(dan)(dan)性(xing)(xing)聯(lian)軸器(qi)屬(shu)金屬(shu)彈(dan)(dan)性(xing)(xing)元件撓性(xing)(xing)聯(lian)軸器(qi)，其依(yi)靠(kao)金屬(shu)聯(lian)軸器(qi)膜片(pian)來聯(lian)接(jie)主(zhu)、從動機(ji)(ji)傳遞扭(niu)矩，具有(you)彈(dan)(dan)性(xing)(xing)減振、無噪聲、不(bu)需潤滑(hua)的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)至少由一(yi)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)兩個(ge)軸(zhou)(zhou)套(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被(bei)用銷(xiao)釘(ding)緊固在(zai)軸(zhou)(zhou)套(tao)上一(yi)般不(bu)會松動或引起膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)軸(zhou)(zhou)套(tao)之間(jian)的(de)反沖。有(you)一(yi)些生產(chan)商提供(gong)兩個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，也(ye)有(you)提供(gong)三個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，中(zhong)間(jian)有(you)一(yi)個(ge)或兩個(ge)剛性元件，兩邊 再連在(zai)軸(zhou)(zhou)套(tao)上。單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)和(he)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)的(de)不(bu)同之處是處理各種偏(pian)(pian)差能力的(de)不(bu)同，鑒于其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的(de)彎(wan)曲(qu)(qu)，所以單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)不(bu)太適應偏(pian)(pian)心(xin)。而(er)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)可以同時曲(qu)(qu)向(xiang)(xiang)不(bu)同的(de)方向(xiang)(xiang)，以此來補償偏(pian)(pian)心(xin)。
