钢球煤磨机结构设计摘要钢球磨煤机用于干式粉磨各种硬度的煤炭之用，本机器用于热电厂加工固定燃料——煤粉，是热电厂制粉系统中主要设备，它只有借助于热风（热风温度不得超过300℃）的干燥和运输，才能良好的工作，当煤粉细度可磨性系数变化时，机器出粒相应修改。本次煤磨机的结构和原理设计来源于生产实际，因此，依照经济、高效、操作方便等原则，除对煤磨机的总体结构进行优化设计，主要包括传动装置和回转装置的设计。由于主要参数的设计和制定对机器本身的影响很大，所以在煤磨机原理设计方面，主要针对参数设计进行了探讨。在完成设计任务的同时，画出传动装置和回转装置的装配图、煤磨机总图、齿圈和端盖零件图。。关键词：轴承部传动部转速功率筒体应力IDesignofballcoalmillsectorABSTRACTBallmillfordrygrindingofcoaluseinavarietyofhardness,themachineusedforprocessingfixed-fuelthermalpowerplants-coalisthemajorthermalpowerplantequipment,millingsystem,itisonlybymeansofhotair(airtemperaturemustnotexceed300℃)dryandtransporttothegoodwork,whenthefinenessofgrindingcoefficientschange,themachineoutoftabletsamendedaccordingly.Thecoalmillstructureandprincipleofdesignfromproductionpractice,therefore,inaccordancewiththeeconomic,efficientandconvenientoperationprinciples,inadditiontotheoverallstructureofthecoalmilltooptimizethedesign,includinggearandtherotarydevice.Asthemainparametersofthedesignanddevelopmentofasignificantimpactonthemachineitself,soinprinciplethedesignofcoalmill,themaindesignfortheparametersdiscussed.Completethedesigntaskinthesametime,drawgear,androtatingequipmentassemblydrawings,generallayoutofcoalmill,ringgearandtheendcappartdrawing.KEYWORDS:BearingDivision，TransmissionDivision，Speed，Power，CylinderstressII目录前言...............................................................................................1第1章机器的概述..............................................................21.1工作原理........................................................................21.2磨煤机的结构..............................................................21.2.1料斗...............................................................................21.2.2轴承部........................................................................21.2.3传动部........................................................................41.2.4回转部........................................................................51.2.5电动机........................................................................61.2.6联轴器........................................................................61.2.7减速器........................................................................71.2.8地基部........................................................................71.2.9保温隔音罩...........................................................71.2.10辅机...........................................................................71.3机器的用途.....................................................................71.4煤磨机的主要技术参数....................................8第2章球磨机主要技术参数的计算.............102.1球磨机的转速...........................................................102.2球磨机的功率...........................................................102.3球磨机的生产能力..............................................102.4研磨体（介质填充率）..............................10第3章煤磨机主要零件强度计算....................113.1筒体强度计算...............................
