Reasonable design and decorate transmission can make the engine power to get the most reasonable use of, so as to improve the dynamic performance and fuel economy cars. Variable speed transmission39;s main function is to change the torque and speed of numerical and direction; Operation is the main purpose of control transmission mechanism, realize the transmission ratio of the gearbox change, which realize the shift, in order to achieve the change from the speed.br/This article refer to the domestic and foreign many papers, and first simply describes the mechanical transmission of the history, the status and effect of the transmission, and discussed its present situation and future development trend. And then we study the basic structure of the mechanical transmission and variable speed principle, which focus on the transmission mechanism mainly shaft and gear the basic structure, characteristic and work principle, mechanical transmission of each block transmission line are briefly analyzed. The articles included a large amount of calculation process, and the specific contents the layout of transmission analysis, the transmission structure paramete nbsp;determination of turning a synchronizer, the structure and the working principle, each block of the gear axis strength check, the intensity, the service life of the bearings calculations, etc.br/Keywords nbsp;Gear, Shaft, Synchronizer, Three axis five gear/ppbr//ppbr//pp目 nbsp;录br/摘 nbsp;要 Ibr/Abstract IIbr/第1章 nbsp;绪论 1br/1.1 本设计的目的和意义 1br/1.2 变速器的发展 1br/1.3变速器的设计要求 3br/1.4设计内容与思路 3br/1.4.1设计内容 3br/1.4.2设计思路 4br/1.5本章小结 4br/第2章 nbsp;变速器的整体结构方案设计 5br/2.1变速器传动机构的型式选择与结构分析 5br/2.1.1变速器传动方案的比较 5br/2.1.2倒档的布置方案 6br/2.2本章小结 7br/第3章 变速器主要参数的选择与齿轮设计 9br/3.1变速器主要参数的选择 9br/3.1.1档位数和传动比 9br/3.1.2中心距 10br/3.1.3齿轮模数 11br/3.1.4压力角α、螺旋角β和齿宽b 12br/3.1.5齿轮的变位系数 13br/3.2各档传动比及其齿轮齿数的确定 13br/3.2.1确定一档齿轮的齿数 13br/3.2.2确定常啮合齿轮副的齿数 14br/3.2.3确定其他档位的齿数 15br/3.2.4确定倒档齿轮的齿数 15br/3.2.5确定齿轮轮齿尺寸 15br/3.3本章小结 16br/第4章 变速器齿轮的强度计算与材料选择 17br/4.1齿轮的主要失效形式 17br/4.2齿轮的强度计算及材料接触应力 17br/4.2.1齿轮弯曲强度计算 17br/4.2.2齿轮材料接触应力 19br/4.3本章小结 21br/第5章 变速器轴的设计与校核 22br/5.1变速器轴的结构和尺寸 22br/5.1.1轴的结构 22br/5.1.2轴的尺寸 22br/5.2轴的校核 23br/5.2.1第一轴的强度与刚度校核 23br/5.2.2第二轴的强度与刚度校核 24br/5.3本章小结 26br/第6章 变速器同步器与操纵机构的设计 27br/6.1同步器设计 27br/6.1.1同步器的工作原理 27br/6.1.2同步环主要参数的确定 28br/6.2变速器的操纵机构 30br/6.2.1操纵机构的功用 30br/6.2.2操纵机构的设计要求 31br/6.2.3变速器的换档位置 32br/6.3本章小结 32br/第7章 轴承的选用与寿命计算 33br/7.1 第一轴轴承选用与计算 33br/7.2第二轴轴承选用与计算 33br/7.3本章小结 34br/第8章 35br/8.1 CATIA软件简介 35br/8.2变速器的软件设计 35br/8.2.1齿轮的建模 35br/8.2.2变速器的装配 38br/8.2.3变速器的仿真 38br/8.3本章小结 40br/结 nbsp;论 41br/致 nbsp;谢 42br/参考文献 43/ppbr//ppbr//ppbr//pp第1章 nbsp;绪论br/1.1 本设计的目的和意义br/随着我国汽车工业不断的壮大，以/ppimg stylefloatnone; title全部文件.jpg src/ueditor/net/upload/2014-09-25/5840e491-de5e-4a61-b7e8-1a6b4aa9ec43.jpg//ppimg stylefloatnone; title变速器操纵机构.jpg src/ueditor/net/upload/2014-09-25/57cb419f-a823-4ca2-9cd3-d24430fd2096.jpg//ppimg stylefloatnone; title三轴五档变速器装配图.jpg src/ueditor/net/upload/2014-09-25/235d7d54-d4d7-41b4-b36c-1be65c9fb1fe.jpg//ppbr//ppbr//ppimg srchttp//www.renrendoc.com/ueditor_s/net/upload/2018-01-26/bc1c06b9-1181-488d-9f07-a80fa916ed9f.jpg stylefloatnone; titleQQ图片20160420144853.jpg//ppimg srchttp//www.renrendoc.com/ueditor_s/net/upload/2018-01-26/245f59b3-b40c-4043-85da-83df87b21689.jpg stylefloatnone; titleQQ图片20160420144913.jpg//ppimg stylefloatnone; title字数统计.jpg src/ueditor/net/upload/2014-09-25/04194b4f-68cc-4e73-b2db-b714f50ecf49.jpg//ppbr//p
