CL型(xing)齒(chi)(chi)(chi)(chi)式聯(lian)軸器是(shi)由齒(chi)(chi)(chi)(chi)數相同的內齒(chi)(chi)(chi)(chi)圈和(he)帶外齒(chi)(chi)(chi)(chi)的凸(tu)緣半聯(lian)軸器等零件組(zu)成。外齒(chi)(chi)(chi)(chi)分為(wei)直(zhi)齒(chi)(chi)(chi)(chi)和(he)鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)兩種齒(chi)(chi)(chi)(chi)形(xing)(xing)，所(suo)謂(wei)鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)即為(wei)將外齒(chi)(chi)(chi)(chi)制成球(qiu)面，球(qiu)面中(zhong)心在齒(chi)(chi)(chi)(chi)輪(lun)軸線上，齒(chi)(chi)(chi)(chi)側間隙較一般齒(chi)(chi)(chi)(chi)輪(lun)大(da)，鼓形(xing)(xing)齒(chi)(chi)(chi)(chi)聯(lian)軸器可(ke)允許較大(da)的角位移(相對于直(zhi)齒(chi)(chi)(chi)(chi)聯(lian)軸器)，可(ke)改善(shan)齒(chi)(chi)(chi)(chi)的接觸條件，提(ti)高傳(chuan)遞(di)轉矩的能(neng)力，延長使用壽(shou)命。

CL型(xing)齒式(shi)聯軸器在工(gong)(gong)作(zuo)(zuo)時，兩軸產生相對位移，內外齒的(de)齒面周(zhou)期性(xing)作(zuo)(zuo)軸向(xiang)相對滑(hua)動，必然形成齒面磨損和功率損耗，因此齒式(shi)聯軸器需在良好潤滑(hua)和密封的(de)狀態(tai)下工(gong)(gong)作(zuo)(zuo)。

CL型(xing)齒式(shi)(shi)聯(lian)(lian)軸器(qi)徑(jing)向尺寸小(xiao)，承載能(neng)力大(da)，常用(yong)于(yu)低速(su)重(zhong)載工況條件的(de)(de)軸系(xi)(xi)傳(chuan)動，如冶金、礦山、起重(zhong)運(yun)輸行業，也適用(yong)于(yu)石(shi)油、化工、通用(yong)機械等行業。高精度并經動平(ping)衡的(de)(de)齒式(shi)(shi)聯(lian)(lian)軸器(qi)可(ke)用(yong)于(yu)高速(su)傳(chuan)動，如燃汽輪機的(de)(de)軸系(xi)(xi)傳(chuan)動。由(you)于(yu)鼓形齒式(shi)(shi)聯(lian)(lian)軸器(qi)的(de)(de)角向補(bu)償大(da)于(yu)直齒式(shi)(shi)聯(lian)(lian)軸器(qi)，國內外均廣泛采用(yong)鼓形齒式(shi)(shi)聯(lian)(lian)軸器(qi)。
