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，傳遞扭(niu)矩大，使(shi)用(yong)壽命長(chang)，免維護(hu)，耐高(gao)溫(wen)，耐酸堿防(fang)腐蝕，適用(yong)于高(gao)溫(wen)高(gao)速及(ji)有腐蝕工況環境(jing)的軸系傳動。

膜(mo)片型聯(lian)(lian)(lian)軸(zhou)器(qi)能補償主動機(ji)(ji)與從(cong)(cong)動機(ji)(ji)之間由于制造誤差、安裝誤差、承載變形以及(ji)溫升變化的影響等(deng)所引起的軸(zhou)向(xiang)、徑向(xiang)和(he)角向(xiang)偏(pian)移。膜(mo)片彈性聯(lian)(lian)(lian)軸(zhou)器(qi)屬(shu)金(jin)屬(shu)彈性元件撓(nao)性聯(lian)(lian)(lian)軸(zhou)器(qi)，其依靠金(jin)屬(shu)聯(lian)(lian)(lian)軸(zhou)器(qi)膜(mo)片來聯(lian)(lian)(lian)接主、從(cong)(cong)動機(ji)(ji)傳遞扭矩，具有彈性減振、無噪聲、不需(xu)潤滑的優點(dian)。

膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)至少(shao)由一(yi)(yi)個(ge)(ge)膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)和(he)(he)兩(liang)個(ge)(ge)軸(zhou)套(tao)組成(cheng)。膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)被(bei)用銷(xiao)釘緊固在軸(zhou)套(tao)上(shang)一(yi)(yi)般不會(hui)松動或引起膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)和(he)(he)軸(zhou)套(tao)之(zhi)間的反沖。有(you)一(yi)(yi)些生產商提(ti)供(gong)(gong)兩(liang)個(ge)(ge)膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)的，也有(you)提(ti)供(gong)(gong)三個(ge)(ge)膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)的，中間有(you)一(yi)(yi)個(ge)(ge)或兩(liang)個(ge)(ge)剛性(xing)元件，兩(liang)邊 再連(lian)在軸(zhou)套(tao)上(shang)。單膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)和(he)(he)雙膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)的不同(tong)之(zhi)處是處理各種偏(pian)差能(neng)力的不同(tong)，鑒于其需要膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)能(neng)復雜的彎曲，所以單膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)不太適應偏(pian)心(xin)。而雙膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)可以同(tong)時曲向(xiang)(xiang)不同(tong)的方向(xiang)(xiang)，以此來補償(chang)偏(pian)心(xin)。
