内蒙古科技大学本科生毕业设计说明题目：φ35m环形加热炉炉底机械设计学生姓名：学号：200540401337专业：机械设计制造及其自动化班级：机械2005—3班指导教师：内蒙古科技大学毕业设计说明书（毕业论文）IΦ35m环形加热炉炉底机械设计摘要本次设计是关于环形加热炉炉底机械的设计，主要对炉底的内外支承辊的结构进行设计和受力分析，对传动系统的选型及设计进行设计计算。前半部分主要是传动系统的选型及炉底的中心定位，该加热炉的加热形式主要是通过炉底的转动对钢坯进行分段加热。在该结构中通过液压马达提供动力，销齿轮进行传动，为加热炉加热钢坯提供转矩。该结构具有对钢坯加热均匀、可以根据要求调节钢坯的布料方式、产量大等优点。主传动系统选用液压马达、三级减速器、末级销齿轮带动炉底进行转动。并精确校核销齿轮、轴承确保设计的实用性。下半部分详细细阐了炉底机械的传动系统的设计。驱动系统选用A2F125W3S3液压传动，这样可以保证传动的稳定性。关键词：加热炉；受力分析；支承辊；传动系统内蒙古科技大学毕业设计说明书（毕业论文）IIFurnacebottomringΦ35mmechanicaldesignAbstractThefurnacedesignisonthebottomringofthemechanicaldesign,mainlyonthebottomofthestructurebothinsideandoutsidetherollerbearingdesignandstressanalysisoftheselectionanddesignoftransmissionsystemdesigncalculation.Mainlythefirsthalfofthedrivesystemandtheselectionofthecenterofthebottomposition,theheatingfurnaceismainlymadethroughthebottomoftherotationtosub-slabheating.Inthestructureofpowerthroughthehydraulicmotor,todrivesalesofgearforthebilletheatingfurnacetoprovidetorque.Thestructureofuniformheatingofthebillet,steelbilletinaccordancewiththerequirementsofthefabric-conditioningmethods,yieldadvantages.Hydraulicmotormaindrivesystemofchoice,three-speedreducer,geardrivesalesattheendofclasstorotatethebottom.Andaccuratetowriteofftheschoolgears,bearingstoensurethepracticalityofthedesign.Detailthesecondhalfofthebottomillustratesthedesignofmechanicaldrivesystem.A2F125W3S3optionalhydraulicdrivesystemdrive,thiscanguaranteethestabilityoftransmission.Keywords:Furnace;stressanalysis;bearingroller;transmission内蒙古科技大学毕业设计说明书（毕业论文）III目录Φ35m环形加热炉炉底机械设计..............................................................................................I第一章概述..............................................................................................................................11.1加热炉简介.................................................................................................................11.1.1环型加热炉的结构..........................................................................................21.1.2环型加热炉的工作过程..................................................................................21.2钢钢加热炉的发展趋势.............................................................................................31.3钢管加热的目的.........................................................................................................51.4钢管的生产工艺.........................................................................................................61.5本次设计的专题部分.................................................................................................7第二章炉底机械的总体设计..................................................................................................82.1概述.............................................................................................................................82.2炉底机械的主要技术要求.........................................................................................82.3炉底机械的机构的设计.............................................................................................82.3.1炉底钢结构......................................................................................................92.3.2支承辊的设计................................................................................................102.3.3定心辊的设计................................................................................................102.3.4传动机构的设计............................................................................................11第三章总体方案设计及优选................................................................................................123.1方案简述...................................................................................................................123.2方案的确定...............................................................................................................143.3本章小结...................................................................................................................15内蒙古科技大学毕业设计说明书（毕业论文）IV第四章传动装置的选择........................................................................................................164.1驱动装置的选择.......................................................................................................164.2传动方案的分析.......................................................................................................174.2.1带、链传动....................................................................................................174.2.2齿轮传动........................................................................................................174.3本章小结...................................................................................................................18第五章炉底中心定位............................................................................................................195.1主要设计参数的设计计算.......................................................................................195.1.1给定参数：....................................................................................................195.1.2初设出料频率.....................
