武汉轻工大学毕业设计设计题目：基于外碾削的立式碾米机的创新设计姓名肖建平学号01051121院系机械工程系专业机械设计制造及其自动化指导教师李诗龙2005年6月摘要机械创新设计就是指利用移植、延伸、思维的扩展、仿生、专利利用、逆向思维等创新方法对机器的结构和原理进行创新。在全面了解现行的碾米机的结构和原理后，发现其存在的问题。为了解决这些问题，对碾米工艺、碾辊条、米刀的表面性状和组合参数等关键技术进行了解和分析研究，利用思维扩展和逆向思维等创新方法对立式碾米机的结构和原理上进行创新，并且成功设计出一种基于外碾削的立式碾米机。该碾米机主要有以下四个创新点：一、碾白原理采用外碾削原理；二、出米嘴可以沿方向任意定位；三、进料机构可实现粗调和微调；四、米糠罩采用的是有机玻璃，这样就很容易观察到碾米室内的情况。关键词：碾米机立式碾米机外碾削碾白原理创新设计0AbstractInnovatingdesignofthemachineisthatuseinnovatingmethods,suchasextend、condense、compoundtodesignorimprovethemachineagain.Afterwecomprehendtheconstructionandprincipleofthemodernwhiteningmachine,wefindoutthattherearesomedrawbacksofthemodernwhiteningmachine.Inordertosettlethedrawbacksofthemodernwhiteningmachine,wedependonthetypeofthericetoresearchthewhiteningtechnologyandmillingdiameter,afterthat,wedesigntoimprovetheconstructionandprincipleoftheverticalmillingmachineagain.Theoutsidewhitenerverticalwhiteningmachineusetheregressivethoughtandothermethodstoimprovetheusualverticalwhiteningmachine,andwedesignanewoutsidewhitenerverticalmachinebycombinetheusualverticalwhiteningmachine’sconstructionandmillingwhitening.Therearefourinnovatingpointsinnewdesignedmachine.Itisdifferencefromtheusual1verticalmillingmachine.Thefirstpointisthattheoutsidewhiteningprincipleisusedintoricewhitener.Thesecondpointisthattheoutletcanbeorientatedinanyangle.Thethirdpointisthattheinletcanberegulatedquicklyand/orslowly.ThefourthpointisthatthematerialofthehoodofthericebranisPlexiglassothatpeoplecaneasilyobservethecircumstanceofthewhitener.Key：RicemillingmachineVerticalwhiteningmachineOutsidewhiteningRicewhiteningprincipleInnovatingdesign目录第1章前言..........................................................４1.1课题的背景和意义.................................................４1.2碾米机的国内外发展状况...........................................５1.3本课题主要设计内容...............................................７第2章碾米原理分析、设计方案论证....................................７2.1碾米原理.........................................................７2.1.1擦离碾白.....................................................８2.1.2碾削碾白.....................................................９2.2设计方案论证及理论分析...........................................９2.2.1传统碾米机类型与碾米工艺特点分析.............................９2.2.2设计要求及方案选择.........................................１４2.3本新型米机的创新点和结构设计...................................１５2.3.1新型碾米机碾白室部分.......................................１５2.3.2排料机构部分...............................................１８2.3.3进料装置部分...............................................１９22.2.4碾白室外罩部分.............................................２０2.2.5总体结构...................................................２０第3章主要设计参数的计算............................................２１3.1碾白辊的设计计算...............................................２１3.1.1单位产量运动面积A和碾白辊筒参数的...
