中文摘要本文主要介绍了斜皮带输送机的构造、特点、应用及布置形式，并详细介绍了其主要零部件，即输送带、支承装置、驱动装置和驱动原理、张紧装置、装载和卸载装置以及清理装置。其中常用的支承装置为托辊，驱动装置为电动滚筒，驱动原理为传动滚筒利用摩擦作用带动输送带运行。张紧装置主要介绍了螺旋式张紧装置、车式张紧装置以及垂直式张紧装置三种，此次设计采用了螺旋式张紧装置。由于被输送的物料为砂子和碎石，设计中装载装置采用导料槽，卸载装置采用护罩，清理装置采用清扫器。同时，本文还详细介绍了该设计中各零部件的一系列选型计算，其中包括了带宽、带速、运行阻力和张力、清扫器阻力、导料槽阻力、进料口物料加速阻力、输送带张力、驱动功率以及制动力矩的计算。最后，还简单介绍了斜皮带输送机的运输安全及设备安全，为我们能更好地、更安全地利用斜皮带输送机提供了必要的保障。关键词：输送带支承装置驱动装置和驱动原理张紧装置带宽驱动功率ABSTRACTThistextmainlyintroducesthestructure,characteristics,appliesandtheformoftheinclinedleatherbeltconveyer,andalsointroducesitsmainassemblyunitsindetail,namelybeltconveyer,supportingdevices,drivingdevicesandthedrivingprinciple,thestretchdevices,theloadingandunloadingdevicesandthecleaningdevices.Amongthemsupportingdevicesusedincommonaretrays,drivingdevicesarethedynamoelectricrollers,thedrivingprincipleisthattherollerdrivesthebeltconveyerbythefrictionfunction.Itmainlyintroducedthreekindsofstretchdevices.Theyarespiraltypestretchdevice,thecartypestretchdevice,andtheperpendiculartypestretchdevice,andthisdesignadoptsthespiraltypestretchdevice.Becausethetransportedmaterialsarethesandandcrushedstones,inthedesignitsloadingdevicesadoptstheguidingslot,theunloadingdevicesadoptstheprotectingcover,cleaningdevicesadoptsthecleaningmachine.Inthemeantime,thistextalsointroducesthecalculationsofeachmainassemblyunitindetailincludingthebeltwidth,thebeltspeed,thecirculateresistanceandthetension,thecleaningmachineresistance,theguidingslotresistance,theaccelerationresistanceatthematerialentry,thebeltconveyertension,thedrivingpowerandthepreventtortion.Attheend,italsointroducestheconveyancesafetyandtheequipmentssafetyofthemachineinbrief,whichprovidesusanecessaryguaranteeinusingtheinclinedleatherbeltconveyermuchbetterandmoresafely.KEYWORDS：thebeltconveyersupportingdevicesdrivingdevicesandthedrivingprinciplestretchdevicesthebeltwidththedrivingpower-ii--PAGEi-目录MACROBUTTONInsertCrossReferenceMACROBUTTONInsertCrossReference第一章斜皮带输送机的构造、特点、应用及布置形式………………………11.
