style="text-indent:25px">鏈傳動(dòng)的失效形式主要有以下幾種:(1)鏈板疲勞破壞鏈在松邊拉力和緊邊拉力的反復(fù)作用下，經(jīng)過一定的循環(huán)次數(shù)，鏈板會(huì)發(fā)生疲勞破壞。正常潤滑條件下，鏈板疲勞強(qiáng)度是限定鏈傳動(dòng)承載能力的主要因素。(2)滾子、套筒的沖擊疲勞破壞鏈傳動(dòng)的嚙入沖擊首先由滾子和套筒承受。在反復(fù)多次的沖擊下，經(jīng)過一定循環(huán)次數(shù)，滾子、套筒可能會(huì)發(fā)生沖擊疲勞破壞。這種失效形式多發(fā)生于中、高速閉式鏈傳動(dòng)中。(3)銷軸與套筒的膠合潤滑不當(dāng)或速度過高時(shí)，銷軸和套筒的工作表面會(huì)發(fā)生膠合。膠合限定了鏈傳動(dòng)的極限轉(zhuǎn)速。(4)鏈條鉸鏈磨損鉸鏈磨損后鏈節(jié)變長，容易引起跳齒或脫鏈。開式傳動(dòng)、環(huán)境條件惡劣或潤滑密封不良時(shí)，極易引起鉸鏈磨損，從而急劇降低鏈條的使用壽命。(5)過載拉斷這種拉斷常發(fā)生于低速重載的傳動(dòng)中。在一定的使用壽命下，從一種失效形式出發(fā)，可得出一個(gè)極限功率表達(dá)式。為了清楚，常用線圖表示。為在正常潤滑條件下，對(duì)應(yīng)各種失效形式的極限功率曲線。圖中陰影部分為實(shí)際上使用的區(qū)域。若潤滑密封不良及工況惡劣時(shí)，磨損將很嚴(yán)重，其極限功率會(huì)大幅度下降。鏈輪的好處您了解嗎？蘇州鏈條鏈輪銷售</p><p
