如何分析聯軸器故障？

聯軸器的選擇首先要看材質,一般有硬質鋁合金.工程塑料,鋼性這三類.

聯lian軸zhou器qi的de選xuan擇ze首shou先xian要yao看kan材cai質zhi
，一yi般ban有you硬ying質zhi鋁lv合he金jin，工gong程cheng塑su料liao，鋼gang性xing這zhe三san類lei。其qi次ci要yao看kan聯lian軸zhou器qi兩liang端duan孔kong徑jing的de大da小xiao，聯lian軸zhou器qi的de外wai徑jing和he長chang度du。最zui主zhu要yao是shi根gen據ju電dian機ji或huo絲si杠gang的de實shi際ji使shi用yong扭niu矩ju來lai選xuan擇ze額e度du扭niu矩ju相xiang當dang的de聯lian軸zhou器qi。如ru果guo您nin選xuan的de聯lian軸zhou器qi扭niu矩ju過guo小xiao，超chao過guo它ta的de額e度du範fan圍wei
，很hen容rong易yi斷duan裂lie。

齒輪聯軸器的故障分析: 起重配件聯軸器的故障：①齒麵磨損嚴重。②內齒圈產生軸向位移量較大

，甚至不能齧合。③發生斷齒現象。④聯軸器對口螺栓折斷。 

上述故障的原因主要有以下幾個方麵： 

第(di)一(yi)
，起(qi)重(zhong)配(pei)件(jian)聯(lian)軸(zhou)器(qi)油(you)量(liang)不(bu)足(zu)或(huo)缺(que)油(you)。或(huo)油(you)脂(zhi)使(shi)用(yong)不(bu)當(dang)，造(zao)成(cheng)油(you)脂(zhi)鈣(gai)化(hua)
，致(zhi)使(shi)齒(chi)麵(mian)間(jian)無(wu)法(fa)潤(run)滑(hua)
，或(huo)潤(run)滑(hua)不(bu)好(hao)產(chan)生(sheng)齒(chi)麵(mian)磨(mo)損(sun)嚴(yan)重(zhong)，這(zhe)種(zhong)情(qing)況(kuang)隻(zhi)要(yao)更(geng)換(huan)新(xin)潤(run)滑(hua)脂(zhi)
，定(ding)期(qi)注(zhu)入(ru)合(he)格(ge)的(de)潤(run)滑(hua)脂(zhi)油(you)，防(fang)止(zhi)漏(lou)油(you)

，油(you)量(liang)充(chong)足(zu)，便(bian)可(ke)避(bi)免(mian)。 

第di二er，兩liang軸zhou水shui平ping度du及ji同tong軸zhou度du誤wu差cha太tai大da，超chao過guo了le聯lian軸zhou器qi所suo能neng補bu償chang的de範fan圍wei，使shi得de軸zhou齒chi與yu內nei齒chi齧nie合he不bu正zheng確que，造zao成cheng局ju部bu接jie觸chu
，而er出chu現xian了le附fu加jia力li矩ju。而er這zhe個ge附fu加jia力li矩ju可ke以yi分fen解jie為wei軸zhou向xiang力li。作zuo用yong於yu內nei齒chi圈quan上shang，這zhe個ge力li的de大da小xiao視shi偏pian差cha的de大da小xiao而er定ding，與yu偏pian差cha成cheng正zheng比bi，偏pian差cha愈yu大da，力li愈yu大da
，導dao致zhi起qi重zhong配pei件jian聯lian軸zhou器qi內nei齒chi圈quan產chan生sheng軸zhou向xiang位wei移yi。如ru果guo位wei移yi量liang偏pian大da將jiang無wu法fa控kong製zhi，致zhi使shi齒chi輪lun磨mo損sun嚴yan重zhong，甚shen至zhi斷duan齒chi，內nei外wai齒chi無wu法fa齧nie合he，直zhi至zhi不bu能neng傳chuan動dong。這zhe種zhong故gu障zhang處chu理li比bi較jiao困kun難nan，需xu停ting產chan處chu理li。即ji重zhong新xin找zhao正zheng，或huo把ba減jian速su器qi側ce重zhong新xin找zhao正zheng，或huo將jiang卷juan筒tong側ce重zhong新xin找zhao正zheng。首shou先xian查zha找zhao出chu偏pian移yi誤wu差cha較jiao大da的de部bu位wei，這zhe樣yang先xian要yao測ce量liang聯lian軸zhou器qi是shi向xiang那na側ce偏pian移yi，即ji測ce量liang主zhu軸zhou的de水shui平ping度du與yu同tong軸zhou度du和he減jian速su器qi主zhu軸zhou的de水shui平ping度du與yu同tong軸zhou度du，重zhong新xin按an質zhi量liang標biao準zhun抄chao平ping找zhao正zheng，即ji可ke消xiao除chu故gu障zhang。另ling外wai，兩liang軸zhou的de水shui平ping度du、tongxinduwuchada，zaochenglianzhouqizhuandongshibiejin。heshangshuqizhongpeijianlianzhouqichilunmosundeyuanyinjibenxiangsi，lianjieluoshuanchushoudaozhengchangzuoyongliwai
