聯軸器有很多的種類，凸緣聯軸器就是其中一種，下面就來一起看看凸緣聯軸器特點。
凸(tu)緣(yuan)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)是(shi)一(yi)種(zhong)結構(gou)非常簡單的(de)(de)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)，主要由兩半(ban)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)和聯(lian)(lian)(lian)接螺栓組成(cheng)。凸(tu)緣(yuan)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)的(de)(de)主要加(jia)工(gong)工(gong)序有聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)軸(zhou)(zhou)(zhou)(zhou)(zhou)套(tao)孔(kong)(kong)裝配前的(de)(de)鏜削、切割和鍵槽的(de)(de)修整(zheng)、聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)端面和其它表面的(de)(de)加(jia)工(gong)等。半(ban)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)的(de)(de)軸(zhou)(zhou)(zhou)(zhou)(zhou)套(tao)孔(kong)(kong)有圓錐孔(kong)(kong)和圓柱孔(kong)(kong)兩種(zhong)形式，圓錐孔(kong)(kong)比圓柱孔(kong)(kong)在工(gong)藝(yi)特性(xing)上(shang)(shang)有較多(duo)的(de)(de)優點.聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)的(de)(de)端面加(jia)工(gong)經(jing)常是(shi)套(tao)裝在軸(zhou)(zhou)(zhou)(zhou)(zhou)上(shang)(shang)進行的(de)(de)，這是(shi)為了使聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)端面上(shang)(shang)的(de)(de)榫能(neng)準確地與軸(zhou)(zhou)(zhou)(zhou)(zhou)中(zhong)(zhong)心(xin)線同心(xin)，在這一(yi)加(jia)工(gong)工(gong)序中(zhong)(zhong)特別要注(zhu)意保(bao)證聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)端面與轉子(zi)軸(zhou)(zhou)(zhou)(zhou)(zhou)的(de)(de)垂(chui)直，同時(shi)應注(zhu)意對中(zhong)(zhong)榫的(de)(de)相互配合(he)是(shi)否符(fu)合(he)要求。對于無對中(zhong)(zhong)榫的(de)(de)凸(tu)緣(yuan)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)，在鉆孔(kong)(kong)后還應該(gai)將兩個半(ban)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)套(tao)合(he)在一(yi)起進行鉸孔(kong)(kong)加(jia)工(gong)。
圓(yuan)錐形軸(zhou)(zhou)(zhou)(zhou)套(tao)孔(kong)(kong)(kong)(kong)容易獲得相(xiang)(xiang)配(pei)(pei)(pei)(pei)合(he)(he)部件(jian)(jian)(jian)之間的(de)(de)同心，聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)與軸(zhou)(zhou)(zhou)(zhou)相(xiang)(xiang)配(pei)(pei)(pei)(pei)合(he)(he)面(mian)的(de)(de)接觸(chu)能達到較(jiao)好的(de)(de)配(pei)(pei)(pei)(pei)合(he)(he)，檢驗(yan)也比較(jiao)方(fang)便(bian)，因此采用(yong)(yong)圓(yuan)錐孔(kong)(kong)(kong)(kong)比較(jiao)普(pu)遍。半聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)一(yi)般由鍛件(jian)(jian)(jian)制成(cheng)，粗加(jia)(jia)工時(shi)每(mei)面(mian)留2-3mm的(de)(de)余量，并(bing)要(yao)(yao)進行(xing)消除(chu)殘余應力的(de)(de)熱處理才能進行(xing)鏜孔(kong)(kong)(kong)(kong)工序(xu)。聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)的(de)(de)鏜孔(kong)(kong)(kong)(kong)通(tong)常在(zai)車床(chuang)上進行(xing)，因為對(dui)(dui)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)軸(zhou)(zhou)(zhou)(zhou)套(tao)孔(kong)(kong)(kong)(kong)加(jia)(jia)工 度要(yao)(yao)求(qiu)很(hen)高，因此孔(kong)(kong)(kong)(kong)的(de)(de)精加(jia)(jia)工通(tong)常用(yong)(yong)磨(mo)削的(de)(de)方(fang)法。聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)外(wai)表面(mian)的(de)(de)精加(jia)(jia)工在(zai)進行(xing)鏜孔(kong)(kong)(kong)(kong)的(de)(de)同一(yi)裝夾中(zhong)進行(xing)。加(jia)(jia)工后的(de)(de)孔(kong)(kong)(kong)(kong)的(de)(de)尺(chi)寸(cun)以及孔(kong)(kong)(kong)(kong)與軸(zhou)(zhou)(zhou)(zhou)配(pei)(pei)(pei)(pei)合(he)(he)表面(mian)的(de)(de)接觸(chu)情(qing)況需要(yao)(yao)檢驗(yan)，對(dui)(dui)于成(cheng)批(pi)生產(chan)的(de)(de)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)，一(yi)般可用(yong)(yong)錐度樣(yang)柱進行(xing)，這可保(bao)證零件(jian)(jian)(jian)的(de)(de)互換性。單(dan)件(jian)(jian)(jian)生產(chan)的(de)(de)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)可將辦(ban)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)套(tao)合(he)(he)在(zai)軸(zhou)(zhou)(zhou)(zhou)端上來(lai)檢驗(yan)。如(ru)果(guo)軸(zhou)(zhou)(zhou)(zhou)與孔(kong)(kong)(kong)(kong)的(de)(de)配(pei)(pei)(pei)(pei)合(he)(he)不(bu)合(he)(he)要(yao)(yao)求(qiu)時(shi)，可以修刮(gua)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)的(de)(de)孔(kong)(kong)(kong)(kong)。
