齒式聯軸器主要件互換性值得我們注意，在國外齒式聯軸器每個規格的零(ling)件都可(ke)以互換，如果其(qi)中(zhong)一(yi)件損壞，可(ke)以用(yong)其(qi)備件單件換，不需整體(ti)換，這就節約了維修(xiu)時間，方便用(yong)戶。齒式(shi)聯軸器的熱(re)處理和機械加工(gong)要求(qiu)，鍛件鍛后應(ying)進行(xing)預熱(re)處理，以改善組織和可(ke)加工(gong)性(xing)(xing)。鍛件性(xing)(xing)能熱(re)處理前應(ying)進行(xing)粗加工(gong)，留些(xie)加工(gong)余(yu)量。

齒式聯軸器性能熱處理，鍛件應進行淬火和回火，以達所要求的性能。性能熱處理后的機加工，機械性能合格后，鍛件加工到需方提供的圖樣所規定的尺寸和表面粗糙度。聯軸器允許倍尺鍛造，一般應作分離熱處理。齒式聯軸器徑向尺寸小，承載能力大，常用于低速重載工況條件的軸系傳動，高精度并經動平衡的齒式聯軸器可用于高速傳動，如燃汽輪機的軸系傳動，鍵在槽內要松緊適度，太緊或太松都會傷鍵和傷槽，太松還會使皮帶打滑或振動。鼓形齒式聯軸器承(cheng)載(zai)能(neng)力和壽命取決(jue)于接(jie)(jie)觸強(qiang)(qiang)度(du)，而齒(chi)面曲率半徑和齒(chi)嚙合角則(ze)直接(jie)(jie)影響接(jie)(jie)觸強(qiang)(qiang)度(du)。

當兩(liang)軸(zhou)(zhou)無(wu)角(jiao)向(xiang)位(wei)移時，聯(lian)(lian)軸(zhou)(zhou)器(qi)的(de)(de)選用(yong)(yong)(yong)補(bu)償(chang)(chang)量(liang)(liang)，許(xu)用(yong)(yong)(yong)徑(jing)向(xiang)補(bu)償(chang)(chang)量(liang)(liang)，兩(liang)軸(zhou)(zhou)端軸(zhou)(zhou)線偏角(jiao)、安(an)裝(zhuang)、裝(zhuang)配(pei)，允許(xu)誤(wu)差為5。由于鼓(gu)形(xing)齒式(shi)(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)角(jiao)向(xiang)補(bu)償(chang)(chang)大(da)于直齒式(shi)(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)，國內外(wai)均廣泛采用(yong)(yong)(yong)鼓(gu)形(xing)齒式(shi)(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)，直齒式(shi)(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)屬(shu)于被淘汰的(de)(de)產品，選用(yong)(yong)(yong)者(zhe)應盡(jin)量(liang)(liang)不選用(yong)(yong)(yong)。齒式(shi)(shi)(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)的(de)(de)潤(run)(run)(run)滑(hua)(hua)方式(shi)(shi)(shi)是強力潤(run)(run)(run)滑(hua)(hua)，潤(run)(run)(run)滑(hua)(hua)油從輪齒底部各個小孔噴入，油受(shou)離心(xin)力作用(yong)(yong)(yong)進入嚙合(he)面，起潤(run)(run)(run)滑(hua)(hua)與冷(leng)卻作用(yong)(yong)(yong)。油經嚙合(he)面后(hou)由齒的(de)(de)兩(liang)側(ce)流出(chu)。這種型式(shi)(shi)(shi)潤(run)(run)(run)滑(hua)(hua)，油流循(xun)環不斷，雜(za)志隨之流出(chu)，且噴入的(de)(de)潤(run)(run)(run)滑(hua)(hua)油在離心(xin)力作用(yong)(yong)(yong)下造(zao)成的(de)(de)壓力進入輪齒嚙合(he)面，所以有較好的(de)(de)潤(run)(run)(run)滑(hua)(hua)冷(leng)卻效果(guo)，適用(yong)(yong)(yong)于高速重(zhong)載的(de)(de)場(chang)合(he)。
