滾針軸承(needle bearing)是帶圓(yuan)柱滾(gun)(gun)子(zi)(zi)(zi)的滾(gun)(gun)子(zi)(zi)(zi)軸(zhou)(zhou)承(cheng),相對其(qi)直徑(jing)(jing)(jing),滾(gun)(gun)子(zi)(zi)(zi)既細又(you)長。這(zhe)種滾(gun)(gun)子(zi)(zi)(zi)稱為滾(gun)(gun)針。盡管具(ju)有較(jiao)小(xiao)(xiao)的截(jie)面,軸(zhou)(zhou)承(cheng)仍具(ju)有較(jiao)高的負(fu)荷承(cheng)受(shou)(shou)能力,滾(gun)(gun)針軸(zhou)(zhou)承(cheng)裝(zhuang)有細而長的滾(gun)(gun)子(zi)(zi)(zi)(滾(gun)(gun)子(zi)(zi)(zi)直徑(jing)(jing)(jing)D≤5mm,L/D≥2.5,L為滾(gun)(gun)子(zi)(zi)(zi)長度),因此徑(jing)(jing)(jing)向結(jie)構(gou)緊湊,其(qi)內(nei)徑(jing)(jing)(jing)尺(chi)寸和載荷能力與其(qi)它類型軸(zhou)(zhou)承(cheng)相同時,外(wai)徑(jing)(jing)(jing)最(zui)小(xiao)(xiao),特別適(shi)用(yong)于(yu)徑(jing)(jing)(jing)向安(an)裝(zhuang)尺(chi)寸受(shou)(shou)限制(zhi)的支承(cheng)結(jie)構(gou)。
根據(ju)使用場合不同(tong),可選用無內圈的(de)(de)軸(zhou)承或(huo)滾(gun)(gun)針(zhen)和(he)保持架組件,此時與(yu)軸(zhou)承相配的(de)(de)軸(zhou)頸表(biao)(biao)面(mian)(mian)和(he)外(wai)殼孔(kong)表(biao)(biao)面(mian)(mian)直接(jie)作為(wei)軸(zhou)承的(de)(de)內、外(wai)滾(gun)(gun)動(dong)表(biao)(biao)面(mian)(mian),為(wei)保證載荷能力和(he)運轉性能與(yu)有(you)套(tao)圈軸(zhou)承相同(tong),軸(zhou)或(huo)外(wai)殼孔(kong)滾(gun)(gun)道表(biao)(biao)面(mian)(mian)的(de)(de)硬度,加工精度和(he)表(biao)(biao)面(mian)(mian)質量應(ying)與(yu)軸(zhou)承套(tao)圈的(de)(de)滾(gun)(gun)道相仿。此種軸(zhou)承僅(jin)能承受徑(jing)向載荷。
滾針軸(zhou)承(cheng)(cheng)裝(zhuang)有細而長(chang)的(de)滾子(zi)(滾子(zi)直(zhi)徑(jing)(jing)D≤5mm,L/D≥2.5,L為(wei)(wei)滾子(zi)長(chang)度),因此徑(jing)(jing)向(xiang)結構緊湊,其內(nei)徑(jing)(jing)尺寸和載(zai)荷能(neng)(neng)力與(yu)其它類型(xing)軸(zhou)承(cheng)(cheng)相(xiang)(xiang)(xiang)同(tong)時(shi)(shi),外徑(jing)(jing)最小,特別適(shi)用(yong)(yong)于徑(jing)(jing)向(xiang)安裝(zhuang)尺寸受(shou)限(xian)制的(de)支承(cheng)(cheng)結果。根據(ju)使用(yong)(yong)場(chang)合不同(tong),可(ke)選用(yong)(yong)無內(nei)圈(quan)的(de)軸(zhou)承(cheng)(cheng)或滾針和保(bao)持架(jia)組件,此時(shi)(shi)與(yu)軸(zhou)承(cheng)(cheng)相(xiang)(xiang)(xiang)配的(de)軸(zhou)頸表(biao)面(mian)(mian)和外殼孔表(biao)面(mian)(mian)直(zhi)接作為(wei)(wei)軸(zhou)承(cheng)(cheng)的(de)內(nei)、外滾動(dong)表(biao)面(mian)(mian),為(wei)(wei)保(bao)證載(zai)荷能(neng)(neng)力和運轉性能(neng)(neng)與(yu)有套圈(quan)軸(zhou)承(cheng)(cheng)相(xiang)(xiang)(xiang)同(tong),軸(zhou)或外殼孔滾道(dao)表(biao)面(mian)(mian)的(de)硬度,加工精(jing)度和表(biao)面(mian)(mian)質量應與(yu)軸(zhou)承(cheng)(cheng)套圈(quan)的(de)滾道(dao)相(xiang)(xiang)(xiang)仿。此種(zhong)軸(zhou)承(cheng)(cheng)僅能(neng)(neng)承(cheng)(cheng)受(shou)徑(jing)(jing)向(xiang)載(zai)荷。
