在市場上比較常見的齒式聯軸器有普通構造齒式聯軸器，鼓形齒式聯軸器，尼龍(long)齒式(shi)聯軸(zhou)器等。其中，鼓型齒式(shi)聯軸(zhou)器型號眾多，應用普(pu)遍。

按其外齒(chi)軸(zhou)(zhou)套軸(zhou)(zhou)向齒(chi)形(xing)的不同，可(ke)分紅三(san)種方式(shi)(shi)(shi)，即直齒(chi)齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)、鼓(gu)形(xing)齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)和特殊鼓(gu)齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)內外齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)。齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)徑向尺寸小(xiao)，承載才能(neng)大，長用于低速(su)重載工況條(tiao)件的軸(zhou)(zhou)系(xi)(xi)傳動(dong)，高精度并經動(dong)均衡的齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)可(ke)用于高速(su)傳動(dong)，如(ru)燃汽(qi)輪機的軸(zhou)(zhou)系(xi)(xi)傳動(dong)。由于鼓(gu)形(xing)齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)的角向補償大于直齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)，均普遍采用鼓(gu)形(xing)齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)，直齒(chi)式(shi)(shi)(shi)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)(qi)屬于被淘(tao)汰的產(chan)品，選(xuan)用者應盡(jin)量不選(xuan)用。

無論那一(yi)(yi)種(zhong)，其(qi)(qi)內(nei)(nei)齒(chi)(chi)(chi)圈(quan)與漸開線(xian)直(zhi)(zhi)齒(chi)(chi)(chi)內(nei)(nei)齒(chi)(chi)(chi)輪除在輪齒(chi)(chi)(chi)的頂隙系數選取上(shang)有所(suo)區別外(wai)(wai)，其(qi)(qi)它都一(yi)(yi)樣。直(zhi)(zhi)齒(chi)(chi)(chi)齒(chi)(chi)(chi)式聯(lian)(lian)(lian)軸器(qi)(qi)的外(wai)(wai)齒(chi)(chi)(chi)軸套的軸向齒(chi)(chi)(chi)坯可加(jia)工成直(zhi)(zhi)線(xian)和圓(yuan)(yuan)(yuan)弧形(xing)兩種(zhong)，而分度圓(yuan)(yuan)(yuan)和齒(chi)(chi)(chi)根圓(yuan)(yuan)(yuan)都為直(zhi)(zhi)線(xian)，這種(zhong)聯(lian)(lian)(lian)軸器(qi)(qi)的嚙合方(fang)式和漸開線(xian)圓(yuan)(yuan)(yuan)柱齒(chi)(chi)(chi)輪內(nei)(nei)外(wai)(wai)齒(chi)(chi)(chi)嚙合完整一(yi)(yi)樣。經過增大內(nei)(nei)外(wai)(wai)齒(chi)(chi)(chi)的齒(chi)(chi)(chi)側間(jian)隙，來補償兩軸間(jian)的相(xiang)對位移，但補償量有限。 鼓形(xing)齒(chi)(chi)(chi)式聯(lian)(lian)(lian)軸器(qi)(qi)外(wai)(wai)齒(chi)(chi)(chi)軸套的齒(chi)(chi)(chi)頂加(jia)工成圓(yuan)(yuan)(yuan)弧，即(ji)齒(chi)(chi)(chi)坯加(jia)工成球(qiu)面(mian)，在齒(chi)(chi)(chi)中心平面(mian)且(qie)與節圓(yuan)(yuan)(yuan)柱面(mian)相(xiang)切的截面(mian)內(nei)(nei)，齒(chi)(chi)(chi)構成鼓形(xing)，即(ji)所(suo)謂的鼓方(fang)式聯(lian)(lian)(lian)軸器(qi)(qi)。其(qi)(qi)特性是：承載才能高，以(yi)彎曲強度計算，在相(xiang)同條件下(xia)，比直(zhi)(zhi)齒(chi)(chi)(chi)齒(chi)(chi)(chi)式聯(lian)(lian)(lian)軸器(qi)(qi)傳送的扭矩進(jin)步15~30%;構造合理，性能牢靠，由(you)于齒(chi)(chi)(chi)側呈鼓形(xing)，使(shi)軸線(xian)在的角度條件下(xia)，其(qi)(qi)接觸狀況得到(dao)，從而降低了(le)接觸應力，消弭了(le)直(zhi)(zhi)齒(chi)(chi)(chi)聯(lian)(lian)(lian)軸器(qi)(qi)齒(chi)(chi)(chi)端部載荷(he)集(ji)中，即(ji)消弭了(le)棱邊擠壓(ya)，了(le)工作性能。
