 管件的经验鉴(jian)定技术
⑴向心(xin)球管(guan)(guan)件(jian)(jian)的(de)鉴定 技术状(zhuang)态(tai)正常(chang)的(de)向心(xin)球管(guan)(guan)件(jian)(jian),其(qi)内、外圈(quan)滚道(dao)应无(wu)剥(bo)落(luo)和严(yan)重磨痕,并呈(cheng)光亮的(de)一(yi)(yi)条圆(yuan)弧(hu)沟槽;所有(you)(you)的(de)滚珠应保持圆(yuan)形,表面(mian)无(wu)斑点、裂(lie)纹和剥(bo)落(luo);保持架不松散、不破碎、未磨穿。当(dang)(dang)用一(yi)(yi)只(zhi)手(shou)(shou)持内圈(quan),另一(yi)(yi)只(zhi)手(shou)(shou)迅速(su)轻(qing)推外圈(quan)旋(xuan)转时(shi)(shi),要求旋(xuan)转平稳,只(zhi)听到滚珠在(zai)滚道(dao)上滚动(dong)(dong)(dong)的(de)轻(qing)微声响,无(wu)振动(dong)(dong)(dong);停(ting)止时(shi)(shi)应逐渐减速(su),停(ting)后无(wu)倒退(tui)现象,正常(chang)的(de)向心(xin)心(xin)球管(guan)(guan)件(jian)(jian),其(qi)内、外圈(quan)与滚动(dong)(dong)(dong)体(ti)(ti)之间(jian)(jian)的(de)间(jian)(jian)隙(xi)为0.005-0.010mm,当(dang)(dang)沿径向晃动(dong)(dong)(dong)内外圈(quan)时(shi)(shi),应感觉无(wu)间(jian)(jian)隙(xi)。使用过的(de)管(guan)(guan)件(jian)(jian),可以用手(shou)(shou)拿着内圈(quan)沿轴(zhou)向晃动(dong)(dong)(dong)几下(xia),当(dang)(dang)外圈(quan)和滚珠有(you)(you)明(ming)显声响时(shi)(shi),说(shuo)明(ming)其(qi)配(pei)合间(jian)(jian)隙(xi)超过了0.03mm,不应再继续使用。   
    ⑵圆锥滚(gun)子管(guan)件的鉴(jian)定 管(guan)件使用后(hou),应(ying)检查滚(gun)动(dong)体与内(nei)(nei)圈(quan)(quan)(quan)滚(gun)道(dao)(dao)是(shi)否有(you)剥落,保持架是(shi)否过于松旷(kuang),内(nei)(nei)圈(quan)(quan)(quan)前(qian)后(hou)边缘是(shi)否完整,外(wai)圈(quan)(quan)(quan)滚(gun)道(dao)(dao)是(shi)否有(you)裂痕。内(nei)(nei)圈(quan)(quan)(quan)和滚(gun)子组合体装入外(wai)圈(quan)(quan)(quan)后(hou),滚(gun)子应(ying)落入滚(gun)道(dao)(dao)中(zhong)间,前(qian)移(yi)量不(bu)(bu)超过1.5mm。其中(zhong)有(you)一项不(bu)(bu)合格,即不(bu)(bu)能(neng)使用。   
  
    ⑶调心滚(gun)子(zi)(zi)(zi)管(guan)(guan)件(jian)(jian)和短(duan)圆(yuan)柱滚(gun)子(zi)(zi)(zi)管(guan)(guan)件(jian)(jian)的鉴定 这类管(guan)(guan)件(jian)(jian)的外圈是可分离的。正常(chang)状(zhuang)态时,内(nei)(nei)、外圈滚(gun)道(dao)和滚(gun)子(zi)(zi)(zi)应(ying)无(wu)破(po)碎、麻(ma)点和较深的磨痕(hen);保(bao)持架应(ying)无(wu)变形并(bing)能将滚(gun)子(zi)(zi)(zi)收拢在内(nei)(nei)圈上;内(nei)(nei)、外圈滚(gun)道(dao)与(yu)滚(gun)子(zi)(zi)(zi)的配合(he)间隙不应(ying)超过0.06mm。   
    ⑷推力球管件(jian)鉴(jian)定 正常状态时,两滚(gun)(gun)道应(ying)无剥(bo)落伤和严重(zhong)磨(mo)损,滚(gun)(gun)珠(zhu)应(ying)无破(po)碎和麻(ma)点;保持架应(ying)无变(bian)形,不(bu)与两个(ge)滚(gun)(gun)道垫圈相(xiang)碰,并将(jiang)滚(gun)(gun)珠(zhu)牢(lao)固地收拢(long)在一起。
