滾針軸承(needle bearing)是(shi)帶(dai)圓柱(zhu)滾(gun)子(zi)(zi)(zi)的滾(gun)子(zi)(zi)(zi)軸(zhou)承(cheng),相對其直(zhi)(zhi)徑(jing),滾(gun)子(zi)(zi)(zi)既細(xi)又長。這種滾(gun)子(zi)(zi)(zi)稱(cheng)為滾(gun)針。盡管具有較小的截面,軸(zhou)承(cheng)仍具有較高的負(fu)荷(he)承(cheng)受能(neng)力,滾(gun)針軸(zhou)承(cheng)裝有細(xi)而(er)長的滾(gun)子(zi)(zi)(zi)(滾(gun)子(zi)(zi)(zi)直(zhi)(zhi)徑(jing)D≤5mm,L/D≥2.5,L為滾(gun)子(zi)(zi)(zi)長度),因(yin)此徑(jing)向結(jie)構(gou)緊湊,其內(nei)徑(jing)尺(chi)寸和(he)載荷(he)能(neng)力與其它類(lei)型(xing)軸(zhou)承(cheng)相同時,外徑(jing)最(zui)小,特(te)別適用(yong)于徑(jing)向安(an)裝尺(chi)寸受限(xian)制的支承(cheng)結(jie)構(gou)。
根據(ju)使用場(chang)合不同(tong),可選用無內(nei)圈(quan)的軸(zhou)承(cheng)(cheng)或滾(gun)(gun)針和(he)保持架組件(jian),此時與(yu)(yu)軸(zhou)承(cheng)(cheng)相(xiang)配(pei)的軸(zhou)頸表面(mian)(mian)(mian)(mian)和(he)外(wai)殼(ke)孔表面(mian)(mian)(mian)(mian)直接作為(wei)軸(zhou)承(cheng)(cheng)的內(nei)、外(wai)滾(gun)(gun)動表面(mian)(mian)(mian)(mian),為(wei)保證(zheng)載荷能(neng)力(li)和(he)運轉(zhuan)性能(neng)與(yu)(yu)有套(tao)圈(quan)軸(zhou)承(cheng)(cheng)相(xiang)同(tong),軸(zhou)或外(wai)殼(ke)孔滾(gun)(gun)道(dao)表面(mian)(mian)(mian)(mian)的硬度,加工精度和(he)表面(mian)(mian)(mian)(mian)質量應與(yu)(yu)軸(zhou)承(cheng)(cheng)套(tao)圈(quan)的滾(gun)(gun)道(dao)相(xiang)仿(fang)。此種軸(zhou)承(cheng)(cheng)僅(jin)能(neng)承(cheng)(cheng)受徑向(xiang)載荷。
滾(gun)(gun)(gun)針軸(zhou)(zhou)承(cheng)(cheng)(cheng)裝有細而(er)長的(de)(de)滾(gun)(gun)(gun)子(滾(gun)(gun)(gun)子直徑D≤5mm,L/D≥2.5,L為滾(gun)(gun)(gun)子長度(du)(du)),因此徑向(xiang)結構(gou)緊湊,其內徑尺(chi)寸(cun)和載(zai)荷(he)能(neng)力(li)與其它類型軸(zhou)(zhou)承(cheng)(cheng)(cheng)相(xiang)(xiang)(xiang)同(tong)(tong)(tong)時(shi),外(wai)(wai)(wai)徑最小(xiao),特(te)別適用于(yu)徑向(xiang)安裝尺(chi)寸(cun)受限制的(de)(de)支承(cheng)(cheng)(cheng)結果。根(gen)據使(shi)用場(chang)合不(bu)同(tong)(tong)(tong),可選用無(wu)內圈(quan)的(de)(de)軸(zhou)(zhou)承(cheng)(cheng)(cheng)或滾(gun)(gun)(gun)針和保持(chi)架組件,此時(shi)與軸(zhou)(zhou)承(cheng)(cheng)(cheng)相(xiang)(xiang)(xiang)配的(de)(de)軸(zhou)(zhou)頸表(biao)(biao)面(mian)和外(wai)(wai)(wai)殼(ke)孔表(biao)(biao)面(mian)直接(jie)作為軸(zhou)(zhou)承(cheng)(cheng)(cheng)的(de)(de)內、外(wai)(wai)(wai)滾(gun)(gun)(gun)動表(biao)(biao)面(mian),為保證載(zai)荷(he)能(neng)力(li)和運轉性能(neng)與有套圈(quan)軸(zhou)(zhou)承(cheng)(cheng)(cheng)相(xiang)(xiang)(xiang)同(tong)(tong)(tong),軸(zhou)(zhou)或外(wai)(wai)(wai)殼(ke)孔滾(gun)(gun)(gun)道表(biao)(biao)面(mian)的(de)(de)硬(ying)度(du)(du),加工精度(du)(du)和表(biao)(biao)面(mian)質量應(ying)與軸(zhou)(zhou)承(cheng)(cheng)(cheng)套圈(quan)的(de)(de)滾(gun)(gun)(gun)道相(xiang)(xiang)(xiang)仿。此種軸(zhou)(zhou)承(cheng)(cheng)(cheng)僅(jin)能(neng)承(cheng)(cheng)(cheng)受徑向(xiang)載(zai)荷(he)。
