卷筒聯軸器是一種(zhong)新型撓性聯(lian)軸(zhou)器(qi)(qi)，主要用(yong)(yong)于(yu)起重(zhong)設備中起升機構(gou)的(de)減速器(qi)(qi)輸出軸(zhou)與鋼絲繩卷筒(tong)的(de)聯(lian)接，也適用(yong)(yong)于(yu)其(qi)它類似的(de)既傳(chuan)遞(di)轉矩又承(cheng)(cheng)受徑向載荷(he)的(de)機械設備，但不能(neng)用(yong)(yong)作需承(cheng)(cheng)受軸(zhou)向載荷(he)的(de)傳(chuan)動。卷筒(tong)工(gong)作時(shi)產生的(de)附加軸(zhou)向載荷(he)必(bi)須(xu)由卷筒(tong)固定(ding)支(zhi)承(cheng)(cheng)座承(cheng)(cheng)受，因此，聯(lian)軸(zhou)器(qi)(qi)安裝(zhuang)時(shi)必(bi)須(xu)保證軸(zhou)向定(ding)位(wei)正確。否則卷筒(tong)工(gong)作時(shi)產生的(de)彈性水平位(wei)移可能(neng)會破壞聯(lian)軸(zhou)器(qi)(qi)的(de)軸(zhou)向限位(wei)，造成聯(lian)接失效，甚至釀(niang)成嚴重(zhong)事故。

卷筒聯軸器由(you)帶鼓形(xing)齒(chi)(chi)(chi)的(de)外(wai)(wai)(wai)齒(chi)(chi)(chi)軸(zhou)套、帶聯接(jie)法蘭和內(nei)齒(chi)(chi)(chi)圈(quan)的(de)外(wai)(wai)(wai)套、帶外(wai)(wai)(wai)球(qiu)面(mian)的(de)承(cheng)載(zai)(zai)環、端(duan)蓋和密(mi)封圈(quan)等(deng)組成，并設(she)有定位(wei)磨損指針、潤(run)(run)滑(hua)油孔(kong)(kong)和通氣孔(kong)(kong)等(deng)。外(wai)(wai)(wai)齒(chi)(chi)(chi)軸(zhou)套和外(wai)(wai)(wai)套構(gou)成的(de)鼓形(xing)齒(chi)(chi)(chi)式聯軸(zhou)器傳遞(di)驅(qu)動功率, 而由(you)承(cheng)載(zai)(zai)環的(de)外(wai)(wai)(wai)球(qiu)面(mian)和外(wai)(wai)(wai)套的(de)內(nei)承(cheng)載(zai)(zai)面(mian)形(xing)成的(de)接(jie)觸副構(gou)成自(zi)動調位(wei)的(de)球(qiu)面(mian)軸(zhou)承(cheng)，承(cheng)受徑(jing)向載(zai)(zai)荷。卷筒用聯軸(zhou)器的(de)內(nei)、外(wai)(wai)(wai)齒(chi)(chi)(chi)嚙合(he)在油浴中(zhong)工作,通過內(nei)外(wai)(wai)(wai)端(duan)蓋、密(mi)封圈(quan)防止(zhi)潤(run)(run)滑(hua)脂泄漏。
