辽宁科技大学本科生毕业设计辽宁科技大学本科生毕业设计PAGEV三辊卷板机设计摘要本设计是关于对称式三辊卷板机的设计，主要对卷板机上、下辊及减速器进行设计和计算。设计前部分详细阐述了卷板机上、下辊结构设计和受力分析。板机结构型式为三辊对称式,在该结构中上辊下压提供压力,两下辊做旋转运动,为卷制板材提供扭矩。它具有结构简单、体积小、重量轻、经济、等优点。动力源则选择了YZ系列YZ160L—6型电机，其工作特性优于Y系列电机，适用于有轻微震动，正反转且转速不高的场合。总体设计后部分所涉及的减速器采用了三级展开式圆柱齿轮结构。齿轮材料为40Cr，并经调质及表面淬火。校核齿轮、轴、键、轴承确保了设计的实际可行性。关键词:卷板机；电动机；减速器；键；齿轮ThreeRollerBendingMachineDesignAbstractThisdesignisaboutthethree-rollersymmwtryrollingmachine,mainlycalcatstheupanddownrollerandthedeceleratorDuringthefrontprocessofthedesign,therollingmachine`sstructucredesignandtheanalysisofstrengtharedescribed.Therollingmachine`structureisthree-rollersymmetry.Pressureprovidespressureunderowingstructuretheabove-averageroller,therollerdoesrevolutionsportundertwo,sheetmaterialprovidesmomentoftorsiontorollofsystem.Ithasaseriesofadvantagessuchassimplystructure,smallvolume,lightweight,economicalandsoon.YZtypeYZ-160L-6motorisselectedasthepowersource,whichadaptssituationsuchassliencequenchingandlightreversevelocity.Thelastpartofthepaperisahoutdeceleratorwhichischoosingtripleexpandingcolummgearconstiuction.Thematerialofgearis40Crwhichhasbeenhardeningsurface.Thegears,axes,keys,bearingsarechecked,sotoconfirmthisdesignispracticalKeywords:Rollingmachine；Motor；Decelerator；Key；Gear目录TOC\o"1-3"\h\z\uHYPERLINK\l_Toc196701绪论PAGEREF_Toc196701HYPERLINK\l_Toc209801.1概述PAGEREF_Toc209801HYPERLINK\l_Toc70151.2卷板机的发展趋势PAGEREF_Toc70153HYPERLINK\l_Toc123812般小型卷板机结构及特点分析PAGEREF_Toc123814HYPERLINK\l_Toc272622.1辊卷板机PAGEREF_Toc272624HYPERLINK\l_Toc108132.2三辊卷板机PAGEREF_Toc108135HYPERLINK\l_Toc217692.2.1对称式三棍卷板机结构及特点PAGEREF_Toc217695HYPERLINK\l_Toc146522.2.2不对称三辊卷板机特点PAGEREF_Toc146525HYPERLINK\l_Toc140342.3方案的确定PAGEREF_Toc140346HYPERLINK\l_Toc306393传动设计PAGEREF_Toc306397HYPERLINK\l_Toc81083.1传动方案的分析及确定PAGEREF_Toc81087HYPERLINK\l_Toc250033.2主传动系统的确定PAGEREF_Toc250038HYPERLINK\l_Toc165673.2.1副传动系统的确定PAGEREF_Toc165678HYPERLINK\l_Toc316594动力设计PAGEREF_Toc316
