鏈條傳動

鏈傳(chuan)動(dong)(dong)(dong)是靠(kao)鏈條之間(jian)的(de)(de)嚙(nie)合(he)來傳(chuan)動(dong)(dong)(dong)兩平(ping)(ping)行軸(zhou)之間(jian)的(de)(de)運(yun)動(dong)(dong)(dong)和(he)動(dong)(dong)(dong)力，屬于(yu)具有(you)嚙(nie)合(he)性(xing)質的(de)(de)強迫傳(chuan)動(dong)(dong)(dong)。與帶傳(chuan)動(dong)(dong)(dong)、齒輪傳(chuan)動(dong)(dong)(dong)相比，鏈傳(chuan)動(dong)(dong)(dong)的(de)(de)主(zhu)要特點是：沒有(you)彈(dan)性(xing)滑(hua)動(dong)(dong)(dong)和(he)打滑(hua)，能保持準確(que)的(de)(de)平(ping)(ping)均(jun)傳(chuan)動(dong)(dong)(dong)比，傳(chuan)動(dong)(dong)(dong)的(de)(de)效率較高(gao)；鏈條不需要像帶傳(chuan)動(dong)(dong)(dong)那樣(yang)張(zhang)的(de)(de)很緊，所以壓軸(zhou)力較小；傳(chuan)遞功率大，過(guo)載(zai)能力強；能在低速重(zhong)載(zai)下(xia)較好工作，能適應惡劣(lie)環境如多塵、油污、腐蝕等(deng)場合(he)。鏈傳(chuan)動(dong)(dong)(dong)的(de)(de)缺點：瞬(shun)間(jian)鏈速和(he)瞬(shun)時(shi)傳(chuan)動(dong)(dong)(dong)比不為常數，工作中有(you)沖擊和(he)噪音，磨(mo)損后(hou)易(yi)發生跳(tiao)齒，不宜在載(zai)荷(he)變化(hua)很大和(he)急速反向(xiang)的(de)(de)傳(chuan)動(dong)(dong)(dong)中應用。
