卷筒聯軸器是一種新(xin)型撓性聯(lian)(lian)(lian)(lian)軸(zhou)器，主要(yao)用(yong)(yong)于起(qi)重設備中起(qi)升機構的減(jian)速(su)器輸出軸(zhou)與鋼絲繩卷(juan)筒(tong)的聯(lian)(lian)(lian)(lian)接(jie)，也適用(yong)(yong)于其它類似的既傳(chuan)遞轉矩又(you)承受徑向(xiang)(xiang)載(zai)(zai)荷(he)的機械設備，但不能用(yong)(yong)作需(xu)承受軸(zhou)向(xiang)(xiang)載(zai)(zai)荷(he)的傳(chuan)動(dong)。卷(juan)筒(tong)工作時(shi)(shi)產生(sheng)的附加軸(zhou)向(xiang)(xiang)載(zai)(zai)荷(he)必須由卷(juan)筒(tong)固定(ding)支承座(zuo)承受，因(yin)此，聯(lian)(lian)(lian)(lian)軸(zhou)器安裝(zhuang)時(shi)(shi)必須保證軸(zhou)向(xiang)(xiang)定(ding)位(wei)正確(que)。否則卷(juan)筒(tong)工作時(shi)(shi)產生(sheng)的彈性水平位(wei)移(yi)可能會破(po)壞(huai)聯(lian)(lian)(lian)(lian)軸(zhou)器的軸(zhou)向(xiang)(xiang)限位(wei)，造成(cheng)聯(lian)(lian)(lian)(lian)接(jie)失效(xiao)，甚至釀(niang)成(cheng)嚴重事故。

卷筒聯軸器由(you)帶鼓形齒(chi)(chi)的(de)外(wai)(wai)(wai)(wai)齒(chi)(chi)軸套(tao)、帶聯接法蘭(lan)和(he)(he)內齒(chi)(chi)圈的(de)外(wai)(wai)(wai)(wai)套(tao)、帶外(wai)(wai)(wai)(wai)球(qiu)(qiu)面的(de)承(cheng)(cheng)(cheng)載環、端(duan)蓋和(he)(he)密(mi)封(feng)圈等組成(cheng)，并(bing)設有(you)定位磨損指針、潤(run)滑(hua)油孔和(he)(he)通氣孔等。外(wai)(wai)(wai)(wai)齒(chi)(chi)軸套(tao)和(he)(he)外(wai)(wai)(wai)(wai)套(tao)構成(cheng)的(de)鼓形齒(chi)(chi)式(shi)聯軸器(qi)傳遞(di)驅(qu)動功率, 而由(you)承(cheng)(cheng)(cheng)載環的(de)外(wai)(wai)(wai)(wai)球(qiu)(qiu)面和(he)(he)外(wai)(wai)(wai)(wai)套(tao)的(de)內承(cheng)(cheng)(cheng)載面形成(cheng)的(de)接觸副構成(cheng)自動調(diao)位的(de)球(qiu)(qiu)面軸承(cheng)(cheng)(cheng)，承(cheng)(cheng)(cheng)受徑向載荷。卷筒用聯軸器(qi)的(de)內、外(wai)(wai)(wai)(wai)齒(chi)(chi)嚙(nie)合在(zai)油浴中工作,通過(guo)內外(wai)(wai)(wai)(wai)端(duan)蓋、密(mi)封(feng)圈防止(zhi)潤(run)滑(hua)脂(zhi)泄漏(lou)。
