彈性柱銷聯軸器傳遞轉矩大，在相同轉矩時回轉直徑大多數比齒式聯軸器小，體積小，質量輕，可部分代替齒式聯軸器，與(yu)齒(chi)式(shi)聯軸器(qi)相比，結構(gou)簡(jian)單，組成零件(jian)較(jiao)少，制(zhi)造較(jiao)方便(bian)，不用齒(chi)輪加工機床。彈性柱(zhu)銷聯軸器(qi)維修方便(bian)，壽命較(jiao)長(chang)，拆下檔(dang)板即可更(geng)換(huan)尼(ni)龍(long)柱(zhu)銷，尼(ni)龍(long)柱(zhu)銷為自潤(run)(run)材料，不需(xu)潤(run)(run)滑，不僅節省潤(run)(run)滑油，而且凈化工作環境(jing)。彈性柱(zhu)銷聯軸器(qi)不足之處是減振動能差，噪(zao)聲較(jiao)大(da)，但成本低，價格便(bian)宜，所以在輸送(song)機械、冶金機械應用很廣泛。

彈性(xing)(xing)柱(zhu)銷(xiao)(xiao)聯(lian)軸(zhou)(zhou)器(qi)(qi)是用(yong)來(lai)帶動(dong)(dong)(dong)(dong)啟動(dong)(dong)(dong)(dong)變(bian)速(su)箱與(yu)起動(dong)(dong)(dong)(dong)發(fa)電機和(he)勵磁機的，柱(zhu)銷(xiao)(xiao)聯(lian)軸(zhou)(zhou)節(jie)主(zhu)要(yao)由主(zhu)動(dong)(dong)(dong)(dong)法蘭(lan)、從動(dong)(dong)(dong)(dong)法蘭(lan)、柱(zhu)銷(xiao)(xiao)及彈性(xing)(xing)橡膠圈等組成(cheng)。彈性(xing)(xing)柱(zhu)銷(xiao)(xiao)聯(lian)軸(zhou)(zhou)器(qi)(qi)具有特(te)定補償兩軸(zhou)(zhou)相對(dui)偏移的性(xing)(xing)能，適用(yong)于中等和(he)較大功率(lv)傳動(dong)(dong)(dong)(dong)，不(bu)適用(yong)于對(dui)減振有特(te)定要(yao)求(qiu)和(he)噪聲需要(yao)嚴加控制的工(gong)作(zuo)部位。彈性(xing)(xing)柱(zhu)銷(xiao)(xiao)聯(lian)軸(zhou)(zhou)器(qi)(qi)是利用(yong)若干非金(jin)屬材料制成(cheng)的柱(zhu)銷(xiao)(xiao)，置于兩半聯(lian)軸(zhou)(zhou)器(qi)(qi)與(yu)外環內表面之間的對(dui)合孔中，通過柱(zhu)銷(xiao)(xiao)傳遞轉矩實現兩半聯(lian)軸(zhou)(zhou)器(qi)(qi)聯(lian)接。

在柱銷和從動法蘭間采用的圓錐面配合，組裝時主、從動法蘭間留有一定的間隙，給工作中橡膠圈的變形留有一定的余地。柱銷聯軸節工作時，通過柱銷和橡膠圈來傳遞力矩，因此使其具有較好的減振和吸振作用，并且允許用一定的同軸度，組裝時其兩軸間的同軸度控制在0.3mm之內。否則容易引起橡膠圈嚴重磨損，縮短其使用壽命而且會引起震動，失去原有的作用及時檢修換，否則將會引起劇烈的振動，影響機車正常的運用。
