GCLD型電動機軸伸鼓形齒式聯軸器在工作時，兩軸產生相對角位移，內外齒的齒面周期性作軸向相對滑動，必然形成齒面磨損和功率消耗，因此，GCLD型電動機軸伸鼓形齒式聯軸器需在有良好和密封的狀態下工作。GCLD型電動機軸伸鼓形齒式聯軸器徑向尺寸(cun)小，承載(zai)(zai)能力大(da)，常(chang)用于(yu)低速重載(zai)(zai)工況條(tiao)件的(de)(de)軸(zhou)(zhou)系(xi)傳(chuan)動(dong)，高精度并經(jing)動(dong)平衡的(de)(de)GCLD型電(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)軸(zhou)(zhou)伸(shen)鼓(gu)(gu)形齒式(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器可用于(yu)高速傳(chuan)動(dong)，如燃汽輪機(ji)(ji)(ji)(ji)的(de)(de)軸(zhou)(zhou)系(xi)傳(chuan)動(dong)。由于(yu)鼓(gu)(gu)形GCLD型電(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)軸(zhou)(zhou)伸(shen)鼓(gu)(gu)形齒式(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器角向補償大(da)于(yu)直GCLD型電(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)軸(zhou)(zhou)伸(shen)鼓(gu)(gu)形齒式(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器，國內(nei)外均廣泛采用鼓(gu)(gu)形GCLD型電(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)軸(zhou)(zhou)伸(shen)鼓(gu)(gu)形齒式(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器，直GCLD型電(dian)(dian)動(dong)機(ji)(ji)(ji)(ji)軸(zhou)(zhou)伸(shen)鼓(gu)(gu)形齒式(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器屬于(yu)被淘汰的(de)(de)產品，選用者(zhe)應盡量不選用。

齒機加工鼓型齒，齒坯只作回轉運動，滾刀中心作圓弧運動，完成對齒坯的垂直進給與水平進給，滾齒機附帶加工鼓型齒的滾刀進給機構時采用此法，此種方法目前較常用。鼓形GCLD型電動機軸伸鼓形齒式聯軸器屬于剛撓性聯軸器，GCLD型電動機軸伸鼓形齒式聯軸器是由齒數相同的內齒圈和帶外齒的凸緣半聯軸器等零件組成。外齒分為直齒和鼓形齒兩種齒形，所謂鼓形齒即為將外齒制成球面，球面中心在齒輪軸線上，齒側間隙較一般齒輪大，鼓形齒聯軸器可(ke)允許(xu)較(jiao)大的(de)角位移（相對于(yu)直齒(chi)聯軸器），可(ke)改善齒(chi)的(de)接觸條件，提高傳遞轉矩的(de)能力，延長使(shi)用壽命。
