cl鼓型齒(chi)(chi)式聯(lian)軸器(qi)(qi)是由齒(chi)(chi)數相同的(de)(de)(de)內齒(chi)(chi)圈和帶外(wai)齒(chi)(chi)的(de)(de)(de)凸緣(yuan)半聯(lian)軸器(qi)(qi)等零(ling)件(jian)(jian)組成。外(wai)齒(chi)(chi)分為(wei)直齒(chi)(chi)和鼓形齒(chi)(chi)兩(liang)種齒(chi)(chi)形，所謂鼓形齒(chi)(chi)即為(wei)將外(wai)齒(chi)(chi)制成球面，球面中心在齒(chi)(chi)輪軸線上，齒(chi)(chi)側間(jian)隙較(jiao)一般齒(chi)(chi)輪大，鼓形齒(chi)(chi)聯(lian)軸器(qi)(qi)可允許較(jiao)大的(de)(de)(de)角位移(yi)(相對于直齒(chi)(chi)聯(lian)軸器(qi)(qi))，可改善齒(chi)(chi)的(de)(de)(de)接觸條(tiao)件(jian)(jian)，提(ti)高傳遞轉矩的(de)(de)(de)能力，延長使用壽命。

cl鼓型齒式(shi)聯軸(zhou)器在工作(zuo)時，兩(liang)軸(zhou)產生相(xiang)對(dui)位移，內外齒的齒面周期性作(zuo)軸(zhou)向相(xiang)對(dui)滑(hua)(hua)動，必然形成齒面磨損和功(gong)率損耗，因此齒式(shi)聯軸(zhou)器需在良好潤滑(hua)(hua)和密封的狀態下工作(zuo)。

cl鼓型齒(chi)(chi)式(shi)(shi)(shi)(shi)聯(lian)(lian)(lian)軸器徑向尺寸小，承載能力大，常用(yong)(yong)(yong)于(yu)低速(su)重載工況條(tiao)件的(de)軸系傳動，如(ru)冶金、礦山、起重運輸行業，也適用(yong)(yong)(yong)于(yu)石油、化工、通用(yong)(yong)(yong)機械等行業。高(gao)精度并(bing)經(jing)動平衡的(de)齒(chi)(chi)式(shi)(shi)(shi)(shi)聯(lian)(lian)(lian)軸器可用(yong)(yong)(yong)于(yu)高(gao)速(su)傳動，如(ru)燃汽輪(lun)機的(de)軸系傳動。由于(yu)鼓形齒(chi)(chi)式(shi)(shi)(shi)(shi)聯(lian)(lian)(lian)軸器的(de)角向補償大于(yu)直齒(chi)(chi)式(shi)(shi)(shi)(shi)聯(lian)(lian)(lian)軸器，國內外均廣泛采用(yong)(yong)(yong)鼓形齒(chi)(chi)式(shi)(shi)(shi)(shi)聯(lian)(lian)(lian)軸器。
