滾針軸承(needle bearing)是帶圓柱滾(gun)(gun)子(zi)的滾(gun)(gun)子(zi)軸承(cheng)(cheng),相(xiang)對其(qi)直徑(jing)(jing)(jing),滾(gun)(gun)子(zi)既細又長。這(zhe)種滾(gun)(gun)子(zi)稱為滾(gun)(gun)針(zhen)。盡(jin)管具有(you)較小的截面,軸承(cheng)(cheng)仍(reng)具有(you)較高的負(fu)荷承(cheng)(cheng)受能力,滾(gun)(gun)針(zhen)軸承(cheng)(cheng)裝(zhuang)有(you)細而長的滾(gun)(gun)子(zi)(滾(gun)(gun)子(zi)直徑(jing)(jing)(jing)D≤5mm,L/D≥2.5,L為滾(gun)(gun)子(zi)長度),因(yin)此徑(jing)(jing)(jing)向結(jie)構緊湊,其(qi)內徑(jing)(jing)(jing)尺寸和載荷能力與其(qi)它(ta)類型軸承(cheng)(cheng)相(xiang)同時,外徑(jing)(jing)(jing)最小,特別適用于(yu)徑(jing)(jing)(jing)向安裝(zhuang)尺寸受限制的支承(cheng)(cheng)結(jie)構。
根據使(shi)用(yong)場合不同,可選用(yong)無內(nei)圈(quan)的軸(zhou)承(cheng)(cheng)或滾(gun)(gun)(gun)針和(he)保(bao)持架組件,此(ci)(ci)時(shi)與軸(zhou)承(cheng)(cheng)相(xiang)配的軸(zhou)頸表(biao)面(mian)(mian)和(he)外殼(ke)孔(kong)(kong)表(biao)面(mian)(mian)直接作為(wei)軸(zhou)承(cheng)(cheng)的內(nei)、外滾(gun)(gun)(gun)動表(biao)面(mian)(mian),為(wei)保(bao)證載(zai)荷能(neng)力和(he)運轉性能(neng)與有套圈(quan)軸(zhou)承(cheng)(cheng)相(xiang)同,軸(zhou)或外殼(ke)孔(kong)(kong)滾(gun)(gun)(gun)道(dao)表(biao)面(mian)(mian)的硬度(du),加(jia)工精度(du)和(he)表(biao)面(mian)(mian)質量應與軸(zhou)承(cheng)(cheng)套圈(quan)的滾(gun)(gun)(gun)道(dao)相(xiang)仿。此(ci)(ci)種軸(zhou)承(cheng)(cheng)僅能(neng)承(cheng)(cheng)受徑向(xiang)載(zai)荷。
滾(gun)針軸(zhou)承(cheng)(cheng)(cheng)裝(zhuang)有細而長(chang)的(de)滾(gun)子(滾(gun)子直(zhi)徑D≤5mm,L/D≥2.5,L為(wei)滾(gun)子長(chang)度),因此徑向結構緊湊,其內徑尺寸和(he)載荷(he)(he)能(neng)力(li)(li)與(yu)其它類型軸(zhou)承(cheng)(cheng)(cheng)相同時(shi),外(wai)(wai)徑最小,特別適用(yong)于徑向安(an)裝(zhuang)尺寸受限制(zhi)的(de)支承(cheng)(cheng)(cheng)結果。根據使用(yong)場(chang)合不(bu)同,可選用(yong)無內圈(quan)(quan)的(de)軸(zhou)承(cheng)(cheng)(cheng)或滾(gun)針和(he)保(bao)持(chi)架組件,此時(shi)與(yu)軸(zhou)承(cheng)(cheng)(cheng)相配的(de)軸(zhou)頸表(biao)面和(he)外(wai)(wai)殼孔(kong)表(biao)面直(zhi)接作為(wei)軸(zhou)承(cheng)(cheng)(cheng)的(de)內、外(wai)(wai)滾(gun)動表(biao)面,為(wei)保(bao)證載荷(he)(he)能(neng)力(li)(li)和(he)運轉性能(neng)與(yu)有套圈(quan)(quan)軸(zhou)承(cheng)(cheng)(cheng)相同,軸(zhou)或外(wai)(wai)殼孔(kong)滾(gun)道表(biao)面的(de)硬(ying)度,加工(gong)精度和(he)表(biao)面質量應與(yu)軸(zhou)承(cheng)(cheng)(cheng)套圈(quan)(quan)的(de)滾(gun)道相仿。此種(zhong)軸(zhou)承(cheng)(cheng)(cheng)僅能(neng)承(cheng)(cheng)(cheng)受徑向載荷(he)(he)。
