矩形花鍵軸 　　

矩形花(hua)鍵(jian)軸應(ying)用(yong)(yong)廣泛(fan)，如(ru)飛機、汽車(che)、拖拉機、機床制造(zao)業、農業機械及一(yi)般機械傳動(dong)(dong)裝置等。 其特(te)點：多齒(chi)(chi)工(gong)(gong)(gong)(gong)(gong)作，承載能(neng)力(li)(li)高，對中(zhong)性(xing)好，導向(xiang)性(xing)好，齒(chi)(chi)根較(jiao)淺，應(ying)力(li)(li)集(ji)中(zhong)小，軸與(yu)轂強度削(xue)弱小，加(jia)工(gong)(gong)(gong)(gong)(gong)方(fang)便(bian)，能(neng)用(yong)(yong)磨削(xue)方(fang)法獲得(de)較(jiao)高的(de)精(jing)度。標準(zhun)中(zhong)有(you)兩個(ge)系列（輕系列和(he)中(zhong)系列）。 　　漸開線花(hua)鍵(jian)軸 　　漸開線花(hua)鍵(jian)軸用(yong)(yong)于載荷較(jiao)大(da)，定心精(jing)度要(yao)求高，以及尺寸較(jiao)大(da)的(de)鏈接。 　　其特(te)點：齒(chi)(chi)廓為漸開線，受載時齒(chi)(chi)上有(you)徑向(xiang)力(li)(li)，能(neng)起自(zi)動(dong)(dong)定心作用(yong)(yong)，使(shi)各齒(chi)(chi)受力(li)(li)均勻，強度高壽命長，加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)與(yu)齒(chi)(chi)輪相同，易獲得(de)較(jiao)高精(jing)度和(he)互換性(xing)。 花(hua)鍵(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)方(fang)法 　　　一(yi)般情況下(xia)，采(cai)用(yong)(yong)線切割加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)。
