滾針軸承(needle bearing)是帶(dai)圓柱(zhu)滾(gun)子(zi)的滾(gun)子(zi)軸承(cheng)(cheng)(cheng)(cheng),相對(dui)其(qi)直徑(jing)(jing),滾(gun)子(zi)既細又長。這種滾(gun)子(zi)稱為滾(gun)針(zhen)。盡管具有(you)較小的截面(mian),軸承(cheng)(cheng)(cheng)(cheng)仍(reng)具有(you)較高的負荷承(cheng)(cheng)(cheng)(cheng)受(shou)能(neng)力(li),滾(gun)針(zhen)軸承(cheng)(cheng)(cheng)(cheng)裝有(you)細而長的滾(gun)子(zi)(滾(gun)子(zi)直徑(jing)(jing)D≤5mm,L/D≥2.5,L為滾(gun)子(zi)長度),因(yin)此徑(jing)(jing)向結構緊湊(cou),其(qi)內徑(jing)(jing)尺(chi)寸(cun)和載(zai)荷能(neng)力(li)與其(qi)它類型軸承(cheng)(cheng)(cheng)(cheng)相同時,外徑(jing)(jing)最小,特別適(shi)用(yong)于(yu)徑(jing)(jing)向安裝尺(chi)寸(cun)受(shou)限制的支承(cheng)(cheng)(cheng)(cheng)結構。
根據使用場合不同,可選用無內圈的軸(zhou)承(cheng)(cheng)或(huo)滾(gun)針和(he)保持架組件,此時與(yu)軸(zhou)承(cheng)(cheng)相(xiang)配的軸(zhou)頸(jing)表(biao)面(mian)(mian)和(he)外(wai)殼孔(kong)表(biao)面(mian)(mian)直接作(zuo)為軸(zhou)承(cheng)(cheng)的內、外(wai)滾(gun)動表(biao)面(mian)(mian),為保證載荷能(neng)力和(he)運轉性能(neng)與(yu)有套圈軸(zhou)承(cheng)(cheng)相(xiang)同,軸(zhou)或(huo)外(wai)殼孔(kong)滾(gun)道表(biao)面(mian)(mian)的硬度,加工(gong)精度和(he)表(biao)面(mian)(mian)質(zhi)量應與(yu)軸(zhou)承(cheng)(cheng)套圈的滾(gun)道相(xiang)仿。此種(zhong)軸(zhou)承(cheng)(cheng)僅(jin)能(neng)承(cheng)(cheng)受徑向(xiang)載荷。
滾(gun)(gun)針軸承(cheng)(cheng)裝有細而長(chang)的滾(gun)(gun)子(滾(gun)(gun)子直徑(jing)(jing)D≤5mm,L/D≥2.5,L為滾(gun)(gun)子長(chang)度(du)),因此徑(jing)(jing)向結構(gou)緊(jin)湊,其內(nei)徑(jing)(jing)尺(chi)寸和(he)載(zai)荷能(neng)力與(yu)其它類(lei)型軸承(cheng)(cheng)相(xiang)(xiang)同(tong)時,外(wai)徑(jing)(jing)最小,特別(bie)適用(yong)于徑(jing)(jing)向安裝尺(chi)寸受限制的支(zhi)承(cheng)(cheng)結果。根據使用(yong)場合不同(tong),可選用(yong)無內(nei)圈的軸承(cheng)(cheng)或滾(gun)(gun)針和(he)保持(chi)架組件,此時與(yu)軸承(cheng)(cheng)相(xiang)(xiang)配的軸頸表面(mian)和(he)外(wai)殼(ke)孔表面(mian)直接作為軸承(cheng)(cheng)的內(nei)、外(wai)滾(gun)(gun)動表面(mian),為保證載(zai)荷能(neng)力和(he)運轉(zhuan)性(xing)能(neng)與(yu)有套圈軸承(cheng)(cheng)相(xiang)(xiang)同(tong),軸或外(wai)殼(ke)孔滾(gun)(gun)道(dao)表面(mian)的硬度(du),加工精度(du)和(he)表面(mian)質量應(ying)與(yu)軸承(cheng)(cheng)套圈的滾(gun)(gun)道(dao)相(xiang)(xiang)仿。此種軸承(cheng)(cheng)僅能(neng)承(cheng)(cheng)受徑(jing)(jing)向載(zai)荷。
