起重機主要機構和零部件如何檢查

    1. 檢查減速器主要看其是否漏油。運行時箱體內有異響，就要打開箱蓋檢查。一般是因軸承損壞或齒輪齧合側隙過大
、齒麵磨損嚴重等原因所致。

　2. 檢查製動器的性能
、狀zhuang況kuang。製zhi動dong器qi是shi起qi重zhong機ji上shang重zhong要yao的de部bu件jian，直zhi接jie影ying響xiang各ge機ji構gou運yun動dong的de準zhun確que性xing和he可ke靠kao性xing。因yin此ci，要yao認ren真zhen檢jian查zha起qi升sheng與yu變bian幅fu兩liang機ji構gou製zhi動dong器qi的de狀zhuang況kuang，觀guan察cha製zhi動dong閘zha瓦wa的de開kai度du及ji摩mo擦ca元yuan件jian刹sha車che皮pi的de磨mo損sun情qing況kuang。帶dai式shi製zhi動dong器qi要yao注zhu意yi檢jian查zha其qi製zhi動dong帶dai的de鋼gang背bei襯chen有you無wu裂lie紋wen，製zhi動dong器qi的de傳chuan動dong是shi否fou靈ling活huo，刹sha車che架jia是shi否fou完wan好hao和he主zhu彈dan簧huang和he輔fu助zhu彈dan簧huang的de彈dan性xing是shi否fou符fu合he要yao求qiu。

　3. 鋼絲繩的檢查。檢查鋼絲繩應著重觀察斷絲

、磨損、扭結
、鏽蝕等情況，對某些磨損、斷duan絲si較jiao為wei嚴yan重zhong但dan尚shang未wei超chao標biao的de位wei置zhi

，要yao做zuo上shang記ji號hao，以yi便bian重zhong點dian跟gen蹤zong複fu檢jian。要yao注zhu意yi檢jian查zha鋼gang絲si繩sheng在zai卷juan筒tong中zhong的de安an全quan限xian位wei器qi是shi否fou有you效xiao，卷juan筒tong上shang的de鋼gang絲si繩sheng壓ya板ban是shi否fou壓ya緊jin及ji壓ya板ban數shu量liang是shi否fou合he適shi。

　5. 檢查各聯軸節有無鬆動甚至"滾鍵"。著(zhe)重(zhong)檢(jian)查(zha)彈(dan)性(xing)柱(zhu)銷(xiao)聯(lian)軸(zhou)節(jie)的(de)彈(dan)性(xing)橡(xiang)膠(jiao)圈(quan)有(you)無(wu)異(yi)常(chang)磨(mo)損(sun)
，對(dui)齒(chi)形(xing)聯(lian)軸(zhou)節(jie)要(yao)特(te)別(bie)注(zhu)意(yi)其(qi)齒(chi)輪(lun)齒(chi)圈(quan)磨(mo)損(sun)狀(zhuang)況(kuang)。因(yin)安(an)裝(zhuang)精(jing)度(du)差(cha)，在(zai)兩(liang)軸(zhou)之(zhi)間(jian)有(you)較(jiao)大(da)偏(pian)移(yi)量(liang)的(de)情(qing)況(kuang)下(xia)
，表(biao)現(xian)為(wei)短(duan)時(shi)間(jian)內(nei)整(zheng)個(ge)齒(chi)圈(quan)很(hen)快(kuai)會(hui)磨(mo)禿(tu)。在(zai)起(qi)升(sheng)機(ji)構(gou)中(zhong)如(ru)有(you)此(ci)種(zhong)情(qing)形(xing)，易(yi)發(fa)生(sheng)嚴(yan)重(zhong)事(shi)故(gu)。
