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)構緊湊(cou)，傳遞扭(niu)矩大，使用(yong)壽(shou)命長，免(mian)維護，耐(nai)高溫(wen)，耐(nai)酸堿(jian)防腐(fu)蝕，適用(yong)于高溫(wen)高速及(ji)有腐(fu)蝕工況(kuang)環境的軸(zhou)系傳動。

膜(mo)片(pian)型聯軸(zhou)器能(neng)補償主動機(ji)與從(cong)動機(ji)之間(jian)由于制造誤(wu)差、安裝誤(wu)差、承載(zai)變形以及溫升變化的影響(xiang)等所引起(qi)的軸(zhou)向、徑向和角向偏移。膜(mo)片(pian)彈性(xing)(xing)聯軸(zhou)器屬金屬彈性(xing)(xing)元件撓性(xing)(xing)聯軸(zhou)器，其依(yi)靠金屬聯軸(zhou)器膜(mo)片(pian)來聯接(jie)主、從(cong)動機(ji)傳遞扭矩，具有(you)彈性(xing)(xing)減振(zhen)、無噪(zao)聲、不(bu)需潤滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器(qi)(qi)(qi)至少由(you)一個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和(he)(he)兩(liang)(liang)個(ge)軸套組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被(bei)用(yong)銷釘緊固在軸套上(shang)一般不(bu)會松動(dong)或(huo)引起膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和(he)(he)軸套之(zhi)間的(de)反(fan)沖。有(you)一些生產商(shang)提(ti)(ti)供兩(liang)(liang)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，也有(you)提(ti)(ti)供三個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，中間有(you)一個(ge)或(huo)兩(liang)(liang)個(ge)剛性元件，兩(liang)(liang)邊 再連在軸套上(shang)。單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器(qi)(qi)(qi)和(he)(he)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器(qi)(qi)(qi)的(de)不(bu)同(tong)(tong)之(zhi)處(chu)是(shi)處(chu)理各種(zhong)偏差能(neng)力(li)的(de)不(bu)同(tong)(tong)，鑒于(yu)其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能(neng)復雜的(de)彎曲，所以單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器(qi)(qi)(qi)不(bu)太適應偏心(xin)。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器(qi)(qi)(qi)可以同(tong)(tong)時曲向不(bu)同(tong)(tong)的(de)方向，以此來補償偏心(xin)。
