尼龍柱銷齒(chi)(chi)(chi)(chi)式聯軸(zhou)(zhou)器(qi)(qi)是由齒(chi)(chi)(chi)(chi)數相同的內齒(chi)(chi)(chi)(chi)圈和帶外(wai)齒(chi)(chi)(chi)(chi)的凸(tu)緣半聯軸(zhou)(zhou)器(qi)(qi)等零件組成。外(wai)齒(chi)(chi)(chi)(chi)分為直齒(chi)(chi)(chi)(chi)和鼓形(xing)齒(chi)(chi)(chi)(chi)兩種齒(chi)(chi)(chi)(chi)形(xing)，所謂鼓形(xing)齒(chi)(chi)(chi)(chi)即為將外(wai)齒(chi)(chi)(chi)(chi)制成球(qiu)面，球(qiu)面中(zhong)心在齒(chi)(chi)(chi)(chi)輪軸(zhou)(zhou)線上，齒(chi)(chi)(chi)(chi)側間隙(xi)較(jiao)一般(ban)齒(chi)(chi)(chi)(chi)輪大，鼓形(xing)齒(chi)(chi)(chi)(chi)聯軸(zhou)(zhou)器(qi)(qi)可允許較(jiao)大的角位移(相對于直齒(chi)(chi)(chi)(chi)聯軸(zhou)(zhou)器(qi)(qi))，可改善齒(chi)(chi)(chi)(chi)的接觸條件，提高傳遞轉矩的能力，延長使用壽(shou)命。

尼龍柱銷齒式(shi)聯軸(zhou)器在工作(zuo)時，兩(liang)軸(zhou)產生(sheng)相(xiang)對位移，內(nei)外齒的(de)齒面周(zhou)期性作(zuo)軸(zhou)向相(xiang)對滑(hua)動，必然形成齒面磨損(sun)和(he)功率(lv)損(sun)耗，因此齒式(shi)聯軸(zhou)器需在良(liang)好潤滑(hua)和(he)密封的(de)狀態下工作(zuo)。

尼龍(long)柱銷齒(chi)式(shi)聯(lian)(lian)軸(zhou)器(qi)徑(jing)向(xiang)尺寸小，承載(zai)能力大(da)，常用(yong)于(yu)低(di)速重載(zai)工(gong)況條件的(de)軸(zhou)系傳(chuan)動，如(ru)冶(ye)金、礦(kuang)山(shan)、起重運(yun)輸(shu)行(xing)業，也適用(yong)于(yu)石油、化工(gong)、通用(yong)機(ji)械等(deng)行(xing)業。高精度并經動平衡的(de)齒(chi)式(shi)聯(lian)(lian)軸(zhou)器(qi)可用(yong)于(yu)高速傳(chuan)動，如(ru)燃汽輪機(ji)的(de)軸(zhou)系傳(chuan)動。由(you)于(yu)鼓(gu)形(xing)齒(chi)式(shi)聯(lian)(lian)軸(zhou)器(qi)的(de)角(jiao)向(xiang)補償大(da)于(yu)直齒(chi)式(shi)聯(lian)(lian)軸(zhou)器(qi)，國內外均廣泛采用(yong)鼓(gu)形(xing)齒(chi)式(shi)聯(lian)(lian)軸(zhou)器(qi)。
