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，傳遞扭(niu)矩大，使用壽命(ming)長，免維護，耐高(gao)溫，耐酸堿防腐蝕，適(shi)用于高(gao)溫高(gao)速及有腐蝕工況(kuang)環境的軸系傳動。

膜片型聯(lian)軸(zhou)(zhou)器(qi)能補償主動機(ji)(ji)與從(cong)動機(ji)(ji)之間由于制(zhi)造誤(wu)差(cha)、安裝誤(wu)差(cha)、承載變形以(yi)及溫升變化(hua)的(de)影響等所引(yin)起的(de)軸(zhou)(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏(pian)移。膜片彈性聯(lian)軸(zhou)(zhou)器(qi)屬金屬彈性元件撓(nao)性聯(lian)軸(zhou)(zhou)器(qi)，其(qi)依靠金屬聯(lian)軸(zhou)(zhou)器(qi)膜片來聯(lian)接主、從(cong)動機(ji)(ji)傳(chuan)遞扭(niu)矩，具有(you)彈性減振、無噪聲、不(bu)需(xu)潤滑的(de)優點(dian)。

膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)至少由一(yi)個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和(he)兩個(ge)(ge)軸套組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被用銷釘(ding)緊固在軸套上(shang)一(yi)般不會松動或引(yin)起膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和(he)軸套之(zhi)間(jian)的反沖。有(you)一(yi)些生產商提(ti)供(gong)兩個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的，也有(you)提(ti)供(gong)三個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的，中間(jian)有(you)一(yi)個(ge)(ge)或兩個(ge)(ge)剛性元件，兩邊 再連在軸套上(shang)。單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)和(he)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)的不同(tong)之(zhi)處是(shi)處理各種偏(pian)差能力的不同(tong)，鑒于其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能復雜的彎(wan)曲(qu)，所(suo)以單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)不太適應偏(pian)心(xin)。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)可以同(tong)時曲(qu)向不同(tong)的方向，以此來補償偏(pian)心(xin)。
