?滑動(dòng)軸承可以用來(lái)密封不同直徑與工作壓力的油,但是如果滑動(dòng)軸承工作不穩(wěn)定,則油將會(huì)變得不穩(wěn)定,而油流量也會(huì)減少因此滑道可能會(huì)逐漸變得狹窄或嚴(yán)重磨損,但隨著時(shí)間的推移,球鉸將逐漸被磨平,使其不能很好地密封。
滑動(dòng)軸承通過(guò)旋轉(zhuǎn),使得滑環(huán)與缸體的間隙不斷減小而滑動(dòng)軸承的滑動(dòng)間隙必須小于等于柱塞泵的油封間隙柱塞泵在使用過(guò)程中,滑環(huán)和缸體之間沒(méi)有間隙當(dāng)滑環(huán)中的滑動(dòng)間隙小于等于0.5mm時(shí),由于受到外力作用,油封之間會(huì)發(fā)生劇烈的摩擦,從而引起缸體漏油。
當(dāng)軸向力大于油封內(nèi)的軸向力時(shí),這種摩擦引起密封件受損此時(shí),滑動(dòng)間隙必須在一定的范圍內(nèi)或稍大于油封本身的間隙如果超過(guò)了這個(gè)范圍,密封就會(huì)出現(xiàn)問(wèn)題因此不能使用滑動(dòng)間隙太小造成泄漏因此只有保證滑環(huán)旋轉(zhuǎn)良好即可,一般將滑環(huán)和油封之間的間隙保持在0.5mm~0.5mm之間。
只有這樣,當(dāng)軸向力超過(guò)油封表面后,滑動(dòng)間隙才能減小,因此安裝滑動(dòng)滾動(dòng)軸承時(shí)一定要保證滑環(huán)和柱塞泵工作時(shí)與油封之間距離至少在1~2mm或者更大 滑動(dòng)軸承可以在缸上安裝一個(gè)滑座當(dāng)滑座固定時(shí),球鉸就成了靜止不動(dòng)的軸承,直到球鉸和油封在同一個(gè)平面上。
球鉸上還有一個(gè)滑動(dòng)軸承,并將其固定在滑座上部和下部這個(gè)滑動(dòng)軸承可以保持滑座內(nèi)部壓力均勻,使系統(tǒng)不會(huì)因液體壓力而發(fā)生不正常變形當(dāng)流體壓力過(guò)大時(shí),它可以阻止液體通過(guò),以防止液體向油封泄漏和磨損滑座滾動(dòng)軸承還可以保持滑座在旋轉(zhuǎn)過(guò)程中不發(fā)生轉(zhuǎn)動(dòng);當(dāng)滑動(dòng)軸承從油封內(nèi)泄漏出來(lái)時(shí),可以防止液體在兩個(gè)油封間流入并進(jìn)入球鉸中,因此它對(duì)流體沒(méi)有任何影響。
