滾針軸承(needle bearing)是(shi)帶(dai)圓(yuan)柱滾(gun)(gun)子(zi)(zi)(zi)的滾(gun)(gun)子(zi)(zi)(zi)軸承(cheng),相對其直(zhi)徑,滾(gun)(gun)子(zi)(zi)(zi)既細又長。這(zhe)種滾(gun)(gun)子(zi)(zi)(zi)稱(cheng)為(wei)滾(gun)(gun)針。盡(jin)管具有(you)較小(xiao)的截面,軸承(cheng)仍具有(you)較高的負荷承(cheng)受能(neng)(neng)力(li),滾(gun)(gun)針軸承(cheng)裝有(you)細而長的滾(gun)(gun)子(zi)(zi)(zi)(滾(gun)(gun)子(zi)(zi)(zi)直(zhi)徑D≤5mm,L/D≥2.5,L為(wei)滾(gun)(gun)子(zi)(zi)(zi)長度),因此(ci)徑向結(jie)構緊湊,其內(nei)徑尺寸(cun)和(he)載(zai)荷能(neng)(neng)力(li)與其它類型軸承(cheng)相同時,外(wai)徑最小(xiao),特別適用于徑向安裝尺寸(cun)受限制的支承(cheng)結(jie)構。
根(gen)據使用(yong)場合不同(tong),可選用(yong)無內圈的軸承(cheng)(cheng)或滾針和(he)保持(chi)架組件,此時(shi)與軸承(cheng)(cheng)相配的軸頸表(biao)面(mian)和(he)外殼(ke)孔(kong)表(biao)面(mian)直接作為軸承(cheng)(cheng)的內、外滾動表(biao)面(mian),為保證載荷能力和(he)運轉性能與有套圈軸承(cheng)(cheng)相同(tong),軸或外殼(ke)孔(kong)滾道表(biao)面(mian)的硬度,加工精度和(he)表(biao)面(mian)質量(liang)應與軸承(cheng)(cheng)套圈的滾道相仿。此種(zhong)軸承(cheng)(cheng)僅能承(cheng)(cheng)受徑向載荷。
滾(gun)針軸(zhou)(zhou)承(cheng)(cheng)(cheng)裝(zhuang)有細而長的滾(gun)子(zi)(滾(gun)子(zi)直徑D≤5mm,L/D≥2.5,L為(wei)(wei)滾(gun)子(zi)長度),因此(ci)(ci)徑向結(jie)構緊湊,其內徑尺(chi)寸和載(zai)荷(he)能(neng)力與(yu)其它類型(xing)軸(zhou)(zhou)承(cheng)(cheng)(cheng)相同時(shi),外(wai)(wai)(wai)徑最小,特別適用(yong)于徑向安裝(zhuang)尺(chi)寸受限制的支承(cheng)(cheng)(cheng)結(jie)果。根據使用(yong)場合不(bu)同,可選用(yong)無內圈(quan)的軸(zhou)(zhou)承(cheng)(cheng)(cheng)或滾(gun)針和保持架組件,此(ci)(ci)時(shi)與(yu)軸(zhou)(zhou)承(cheng)(cheng)(cheng)相配的軸(zhou)(zhou)頸(jing)表面(mian)(mian)(mian)和外(wai)(wai)(wai)殼(ke)孔表面(mian)(mian)(mian)直接作為(wei)(wei)軸(zhou)(zhou)承(cheng)(cheng)(cheng)的內、外(wai)(wai)(wai)滾(gun)動表面(mian)(mian)(mian),為(wei)(wei)保證載(zai)荷(he)能(neng)力和運轉性(xing)能(neng)與(yu)有套圈(quan)軸(zhou)(zhou)承(cheng)(cheng)(cheng)相同,軸(zhou)(zhou)或外(wai)(wai)(wai)殼(ke)孔滾(gun)道(dao)表面(mian)(mian)(mian)的硬度,加(jia)工(gong)精(jing)度和表面(mian)(mian)(mian)質量(liang)應與(yu)軸(zhou)(zhou)承(cheng)(cheng)(cheng)套圈(quan)的滾(gun)道(dao)相仿。此(ci)(ci)種軸(zhou)(zhou)承(cheng)(cheng)(cheng)僅能(neng)承(cheng)(cheng)(cheng)受徑向載(zai)荷(he)。
