PAGEI摘要电动滚筒作为一种新型的驱动装置，已经广泛的应用于各行各业作为输送机械等设备的驱动装置。电动滚筒的主要优点是结构紧凑、传动效率高、噪声低、使用寿命长、运转平稳、工作可靠、密封性能好、占据空间小、安装维修方便，适合在各种恶劣的环境条件下工作。它将电动机和减速器共同置于滚筒体内部，从而提高了滚筒传动的效率。在滚筒体设计中我选用了薄形筒体的经验公式，在传动设计中我选择的是NGW型行星齿轮传动，第一级采用内齿圈固定，行星架输出，第二级采用行星架固定，内齿圈输出。行星齿轮传动中行星轮可以分担负荷，传动结构更为紧凑。为了充分发挥行星齿轮传动的优点，采用了均载机构使各个行星齿轮都能够分担载荷，以补偿不可避免的误差，降低了不均匀系数，提高承载能力。关键字：电动滚筒行星齿轮传动传动比ABSTRACTAsanewtypeofdrivingdevices,ElectricRollerhasbeenwidelyappliedastransportationequipmentsuchasmechanicaldevicesdriventothevarioussectors.ThemainadvantageoftherollerisCohesive,efficienttransmissionandlownoise,longlifeandsmoothoperation,working,reliable,goodperformancesealed,asmallspace,installationmaintenanceconvenience,andSuitablefortheharshenvironmentinavarietyofconditions.Reducercommonelectricmotorsandmachineswillbeplacedwithinthebody,Thusenhancingtheefficiencyofrollermill.InrollerIchooseathin-shapeddesignexperiencecylinderformula,intransmissiondesignIchoseNGW-planetarygeartransmission.First-classIuseoffixedgear,andthePlanet-export.Second-classIUsingplanetaryfixed,andofgearexport.Planetarygeartransmissioncansharetheloadofplanetaryround,sotransmissionstructuremorecompact.Tobringintofullplaytheadvantagesofplanetarygeartransmissionandareusedtosetthevariousagenciescansharetheloadplanetarygeartocompensatetheinevitableerrorsandreducingunevenfactorincreasecarryingcapacitytogether.Keywords:ElectricRoller,Planetarygeartransmission,Velocityratio.目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc388600298"1绪论PAGEREF_Toc388600298\h1HYPERLINK\l"_Toc388600299"1.1电动滚筒行业与产品介绍PAGEREF_Toc388600299\h1HYPERLINK\l"_Toc388600300"1.2电动滚筒的发展PAGEREF_Toc388600300\h3HYPERLINK\l"_Toc388600301"1.3设计参数及要求PAGEREF_Toc388600301\h4HYPERLINK\l"_Toc388600302"1.4方案确定PAGEREF_Toc388600302\h4HYPERLINK\l"_Toc388600303"2电动机的选择PAGEREF_Toc388600303\h6HYPERLINK\l"_Toc388600304"3行星齿轮传动设计与校核PAGEREF_Toc388600304\h7HYPERLINK\l"_Toc388600305"3.1传动方案PAGEREF_Toc388600305\h7HYPERLINK\l"_Toc388600
