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(jin)湊，傳(chuan)遞扭矩大(da)，使用壽命長，免(mian)維護(hu)，耐(nai)高(gao)溫(wen)，耐(nai)酸堿防腐蝕，適用于高(gao)溫(wen)高(gao)速及有腐蝕工況環境的軸系傳(chuan)動。

膜片(pian)型聯(lian)軸(zhou)器(qi)(qi)能補(bu)償主動機(ji)(ji)與從動機(ji)(ji)之(zhi)間由(you)于制造誤(wu)差、安裝誤(wu)差、承載變形以及溫升(sheng)變化(hua)的影(ying)響等(deng)所引(yin)起的軸(zhou)向、徑向和(he)角向偏(pian)移。膜片(pian)彈性(xing)聯(lian)軸(zhou)器(qi)(qi)屬金(jin)屬彈性(xing)元件撓(nao)性(xing)聯(lian)軸(zhou)器(qi)(qi)，其依靠金(jin)屬聯(lian)軸(zhou)器(qi)(qi)膜片(pian)來聯(lian)接主、從動機(ji)(ji)傳遞扭(niu)矩(ju)，具有彈性(xing)減振、無(wu)噪聲、不(bu)需潤(run)滑的優點。

膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)至少由一(yi)個(ge)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和(he)(he)(he)兩個(ge)軸套組成。膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)被用銷釘緊固(gu)在(zai)軸套上(shang)一(yi)般不(bu)會松動或引起膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和(he)(he)(he)軸套之間(jian)的(de)反(fan)沖。有一(yi)些生產商提供兩個(ge)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)，也有提供三個(ge)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)，中間(jian)有一(yi)個(ge)或兩個(ge)剛性元(yuan)件，兩邊 再連在(zai)軸套上(shang)。單膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)和(he)(he)(he)雙膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)的(de)不(bu)同(tong)之處是處理各(ge)種偏差能(neng)力的(de)不(bu)同(tong)，鑒于其需要(yao)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)能(neng)復雜的(de)彎曲，所(suo)以單膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)不(bu)太適(shi)應(ying)偏心。而雙膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)可(ke)以同(tong)時曲向不(bu)同(tong)的(de)方向，以此來補償偏心。
