tgl型鼓形(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)式聯軸(zhou)(zhou)器(qi)是(shi)由齒(chi)(chi)(chi)(chi)(chi)數相同的(de)(de)內齒(chi)(chi)(chi)(chi)(chi)圈(quan)和帶外齒(chi)(chi)(chi)(chi)(chi)的(de)(de)凸緣(yuan)半聯軸(zhou)(zhou)器(qi)等零件組(zu)成。外齒(chi)(chi)(chi)(chi)(chi)分(fen)為直齒(chi)(chi)(chi)(chi)(chi)和鼓形(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)兩(liang)種齒(chi)(chi)(chi)(chi)(chi)形(xing)(xing)(xing)，所謂鼓形(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)即為將外齒(chi)(chi)(chi)(chi)(chi)制成球(qiu)面(mian)，球(qiu)面(mian)中心(xin)在齒(chi)(chi)(chi)(chi)(chi)輪(lun)軸(zhou)(zhou)線上，齒(chi)(chi)(chi)(chi)(chi)側間隙較(jiao)一般(ban)齒(chi)(chi)(chi)(chi)(chi)輪(lun)大(da)，鼓形(xing)(xing)(xing)齒(chi)(chi)(chi)(chi)(chi)聯軸(zhou)(zhou)器(qi)可(ke)允許較(jiao)大(da)的(de)(de)角(jiao)位移(相對于(yu)直齒(chi)(chi)(chi)(chi)(chi)聯軸(zhou)(zhou)器(qi))，可(ke)改善齒(chi)(chi)(chi)(chi)(chi)的(de)(de)接觸條(tiao)件，提高(gao)傳遞轉矩(ju)的(de)(de)能力，延長使用壽命(ming)。

tgl型(xing)鼓(gu)形(xing)齒(chi)(chi)式(shi)(shi)聯軸(zhou)(zhou)器(qi)在(zai)工作(zuo)時，兩軸(zhou)(zhou)產生相對位移，內(nei)外(wai)齒(chi)(chi)的齒(chi)(chi)面(mian)周期(qi)性(xing)作(zuo)軸(zhou)(zhou)向相對滑(hua)動(dong)，必然形(xing)成齒(chi)(chi)面(mian)磨損(sun)和功率損(sun)耗(hao)，因此齒(chi)(chi)式(shi)(shi)聯軸(zhou)(zhou)器(qi)需在(zai)良好(hao)潤滑(hua)和密封(feng)的狀態(tai)下工作(zuo)。

tgl型鼓形(xing)齒(chi)式聯軸(zhou)器徑向尺寸(cun)小，承載(zai)能力大(da)，常用于(yu)低速重載(zai)工(gong)況(kuang)條件(jian)的(de)(de)(de)軸(zhou)系傳(chuan)(chuan)動(dong)(dong)(dong)，如(ru)冶金、礦山、起重運輸行(xing)業，也適用于(yu)石油、化工(gong)、通用機械等行(xing)業。高精度(du)并經動(dong)(dong)(dong)平衡的(de)(de)(de)齒(chi)式聯軸(zhou)器可用于(yu)高速傳(chuan)(chuan)動(dong)(dong)(dong)，如(ru)燃汽輪機的(de)(de)(de)軸(zhou)系傳(chuan)(chuan)動(dong)(dong)(dong)。由于(yu)鼓形(xing)齒(chi)式聯軸(zhou)器的(de)(de)(de)角向補償大(da)于(yu)直齒(chi)式聯軸(zhou)器，國內外均廣泛采(cai)用鼓形(xing)齒(chi)式聯軸(zhou)器。
