1、帶式輸送機輸送帶跑偏原因
1.1滾筒在加工過程中有錐度，形成了“yitoudayitouxiao，shiguntongzaigudongzhong，liangduandexiansudubuyizhi，congerdaozhiyuqimocaerchuandongdeshusongdailiangcesuduyikuaiyiman，jiaodaijiupaopian。zhegewentibujinshishengchanchangjiayaobaguan，yonghuzaiweixiugenghuanyeyaozhuyibimiancileiguntongdeanzhuangshiyong。

1.3安(an)裝(zhuang)中(zhong)或(huo)使(shi)用(yong)一(yi)段(duan)時(shi)間(jian)後(hou)，滾(gun)筒(tong)中(zhong)心(xin)線(xian)與(yu)輸(shu)送(song)帶(dai)的(de)中(zhong)心(xin)線(xian)不(bu)垂(chui)直(zhi)，膠(jiao)帶(dai)就(jiu)會(hui)跑(pao)向(xiang)一(yi)邊(bian)，此(ci)時(shi)，應(ying)調(tiao)整(zheng)滾(gun)筒(tong)位(wei)置(zhi)，使(shi)其(qi)中(zhong)心(xin)線(xian)盡(jin)可(ke)能(neng)與(yu)輸(shu)送(song)帶(dai)的(de)中(zhong)心(xin)線(xian)垂(chui)直(zhi)。
1.4由you於yu輸shu送song物wu料liao向xiang輸shu送song帶dai拋pao放fang時shi不bu均jun勻yun，即ji輸shu送song帶dai上shang承cheng載zai的de物wu料liao在zai寬kuan度du方fang向xiang一yi邊bian重zhong一yi邊bian輕qing，導dao致zhi膠jiao帶dai在zai承cheng載zai段duan跑pao偏pian。對dui此ci應ying采cai用yong前qian傾qing托tuo輥gun組zu，使shi膠jiao帶dai產chan生sheng向xiang中zhong心xin的de回hui複fu力li，實shi施shi糾jiu偏pian。如ru果guo采cai用yong結jie構gou相xiang對dui完wan善shan，費fei用yong也ye相xiang對dui較jiao高gao的de調tiao心xin托tuo輥gun組zu，效xiao果guo更geng佳jia。
2、運輸帶的自動糾偏或調節糾偏的改進措施

2.2改進托輥支架設計 實shi施shi單dan個ge托tuo輥gun前qian傾qing或huo後hou傾qing調tiao節jie糾jiu偏pian。托tuo輥gun的de前qian傾qing或huo後hou傾qing調tiao節jie已yi被bei實shi踐jian證zheng明ming是shi有you效xiao糾jiu偏pian調tiao節jie手shou段duan。以yi往wang是shi托tuo輥gun成cheng組zu前qian傾qing安an裝zhuang來lai實shi施shi整zheng體ti膠jiao帶dai跑pao偏pian的de糾jiu正zheng，現xian單dan個ge托tuo輥gun調tiao節jie，可ke不bu停ting機ji操cao作zuo，提ti高gao效xiao率lv。
2.3適當調節槽型托架的槽型角 目前最常用的槽型角為35°，較大的槽型角既可加大載料的橫端麵，並能在一定程度上防止膠帶跑偏。
2.4在下部加反壓托輥反壓托輥相當於普通槽型托輥倒置，即所謂“反V型托輥”。當膠帶發生偏移時，兩側托輥即在膠帶上造成側向壓力，從而引導膠帶回到中間位置。
輸送帶糾偏總的思路是促使輸送帶在寬度方向所受合力為零，使膠帶工作中拉應力能在寬度方向均勻分布或對稱分布。這個問題在上料、承載、傳動、拉緊、回程、清掃、gaixiangdenggegehuanjiedouyouyingxiangyinshu。zaigaishanshusongdaipaopiandetongshi，wangwanghuizengtianfujiademocagonghao，yehuizengjiayixiezhizaochengben，zhexiezhichuxiangduiyushengchanlvgao、輸送距離長、工作平穩、能量消耗低、使用日益廣泛的帶式輸送機如何取舍，有待於相關方綜合平衡。
