设计（论文）用纸第页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ABSTRACTThisdesignisaboutthethree-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"1-2"\h\z\uHYPERLINK\l"_Toc200201144"摘要PAGEREF_Toc200201144\h1HYPERLINK\l"_Toc200201145"ABSTRACTPAGEREF_Toc200201145\h2HYPERLINK\l"_Toc200201146"HYPERLINK\l"_Toc200201147"绪论PAGEREF_Toc200201147\h4HYPERLINK\l"_Toc200201148"第1章卷板机的原理PAGEREF_Toc200201148\h6HYPERLINK\l"_Toc200201149"1.1卷板机的运动形式PAGEREF_Toc200201149\h6HYPERLINK\l"_Toc200201150"1.2弯曲成型的加工方式PAGEREF_Toc200201150\h6HYPERLINK\l"_Toc200201151"第2章方案的论证及确定PAGEREF_Toc200201151\h8HYPERLINK\l"_Toc200201152"2.1方案的论证PAGEREF_Toc200201152\h8HYPERLINK\l"_Toc200201153"2.2方案的确定PAGEREF_Toc200201153\h10HYPERLINK\l"_Toc200201154"第3章传动设计PAGEREF_Toc200201154\h11HYPERLINK\l"_Toc200201155"3.1传动方案的分析PAGEREF_Toc200201155\h11HYPERLINK\l"_T
