I摘要随着现代科学技术的日益发展，螺旋输送机的应用也越来越广泛。物料从进料口加入，当转轴转动时，物料受到螺旋叶片法向推力的作用。该推力的径向分力和叶片对物料的摩擦力，有可能带着物料绕轴转动，但由于物料本身的重力和料槽对物料的摩擦力的缘故，才不与螺旋叶片一起旋转，而在叶片法向推力的轴向分力作用下，沿着料槽轴向移动。本设计以建筑业为背景，对此工况下所要求的螺旋输送机结构进行设计与计算，对整个装置中的传动系统进行了运动力学分析及结构设计，对其驱动装置做了深入设计，并着重对其主要零部件进行了具体设计，包括螺旋输送机的螺旋直径，螺距，轴径进出料口，叶片形式，中间悬挂轴承，槽体，螺旋轴的计算选型。电动机是通过螺旋输送机的功率来计算选型。减速器中齿轮通过齿面接触疲劳强度来计算，通过齿根弯曲疲劳强度验算；轴按许用弯曲应力计算法校核轴径。关键词电动机；减速器；螺旋叶片；螺旋轴IIAbstractWiththegrowingofmodernscienceandtechnologydevelopment,applicationofthescrewconveyorismoreandmorewidely.Whenthematerialwasaddedtotheinletorifice,andtheshaftrotated,thematerialswasgiventhethrustbythehelicallobe.Thethrustoftheradialcontributetothematerialandbladethefriction,itispossiblethatthematerialscouldrotatearoundtheaxis,butbecauseofthegravityofthematerialandthefrictionwhichthesiloacted,thematerialdonotrotatewiththehelicallobe,itmovealongtheaxisofthesilobythethrustofthespiralblade.Fortheconstructionindustrybackground,whichisrequiredbythescrewconveyordesignandstructureinthisdesign.Theentiredeviceinthetransmissionsystemforthemovementofmechanicalandstructuralwasdesigned.Thedesignofitsdrivingsystemandthespecificdesignofitsmainparts,whichisincludingthescrewconveyorspiraldiameter,pitch,theshaftdiameterofinletorifice,thecalculationandselectionoftheshafts,themiddlehoistandthespiralaxiswerecarriedout.Indetal,motoristhroughthepowerofthescrewconveyortocalculateandselect.Thegearsinthereduceriscalculatedbythegearsurfacecontactfatiguestrengthandcheckedbythegearbottombendfatiguestrength,IcheckthediameterofaxlethroughthepermissiblebendingstressKeywordsmotorreducerhelicallobespiralaxisI目录1绪论.............................................................................................................................................11.1螺旋输送机产品概述..........................................................................................................11.2螺旋输送机应用范围..........................................................................................................11.3螺旋输送机主要特点..........................................................................................................21.4螺旋输送机工作原理..........................................................................................................21.5螺旋输送机整机布置形式..................................................................................................21.6螺旋输送机规格、技术参数..............................................................................................62.电动机的计算选型.....................................................................................................................92.1电动机的选择......................................................................................................................92.2传动装置的运动和动力参数的计算................................................................................103.减速器设计计算.......................................................................................................................133.1齿轮设计............................................................................................................................133.3减速器结构设计................................................................................................................193.3轴设计................................................................................................................................203.4轴承的选型........................................................................................................................253.5键的选型............................................................................................................................264.螺旋输送机机体的设计...........................................................................................................304.1机体主要部件的介绍........................................................................................................304.2机体主要部件的选择计算................................................................................................395.螺旋输送机机体的安装条件、使用及维护...........................................................................455.1螺旋输送机机体的安装条件............................................................................................455.2螺旋输送机机体的使用及维护........................................................................................47结论...............................................................................................................................................49致谢...............................................................................................................................................50参考文献.......................................................................................................................................51附录...............................................................................................................................................52附录一........................................................................................................................................52英文资料......................................
