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(gou)緊湊(cou)，傳遞扭(niu)矩(ju)大，使(shi)用壽(shou)命(ming)長，免維護(hu)，耐高溫(wen)(wen)，耐酸堿防(fang)腐蝕，適(shi)用于(yu)高溫(wen)(wen)高速及有(you)腐蝕工況(kuang)環境(jing)的(de)軸系傳動。

膜片(pian)(pian)型(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)能補償主動機(ji)與從動機(ji)之間由(you)于制造(zao)誤差、安(an)裝誤差、承載變形(xing)以及溫升(sheng)變化的影(ying)響等(deng)所引起(qi)的軸(zhou)向(xiang)、徑向(xiang)和(he)角向(xiang)偏移(yi)。膜片(pian)(pian)彈(dan)性(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)屬金屬彈(dan)性(xing)元件撓性(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)，其依靠金屬聯(lian)(lian)軸(zhou)器(qi)(qi)膜片(pian)(pian)來聯(lian)(lian)接主、從動機(ji)傳遞(di)扭矩，具有彈(dan)性(xing)減振(zhen)、無噪聲、不需潤滑(hua)的優點。

膜(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸器(qi)至少由(you)一(yi)個膜(mo)(mo)(mo)(mo)片(pian)(pian)和兩(liang)個軸套組成。膜(mo)(mo)(mo)(mo)片(pian)(pian)被用銷釘緊(jin)固在軸套上一(yi)般(ban)不(bu)(bu)會松動或引起膜(mo)(mo)(mo)(mo)片(pian)(pian)和軸套之(zhi)間的(de)(de)反沖。有(you)一(yi)些生產(chan)商提供兩(liang)個膜(mo)(mo)(mo)(mo)片(pian)(pian)的(de)(de)，也有(you)提供三個膜(mo)(mo)(mo)(mo)片(pian)(pian)的(de)(de)，中間有(you)一(yi)個或兩(liang)個剛性(xing)元(yuan)件(jian)，兩(liang)邊 再連(lian)在軸套上。單膜(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸器(qi)和雙膜(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸器(qi)的(de)(de)不(bu)(bu)同(tong)(tong)之(zhi)處是(shi)處理各種偏(pian)差(cha)能(neng)力的(de)(de)不(bu)(bu)同(tong)(tong)，鑒于其需(xu)要膜(mo)(mo)(mo)(mo)片(pian)(pian)能(neng)復雜的(de)(de)彎曲，所以單膜(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸器(qi)不(bu)(bu)太適(shi)應偏(pian)心。而雙膜(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸器(qi)可以同(tong)(tong)時(shi)曲向(xiang)不(bu)(bu)同(tong)(tong)的(de)(de)方向(xiang)，以此來補償偏(pian)心。
