起重配件聯軸器的故障

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.

　　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。如ru曾zeng發fa現xian過guo此ci類lei故gu障zhang
，提ti升sheng機ji為weiJK一2．5／11．5單繩纏繞式提升機，當時測得聯軸器的同心度偏差2n
