编辑推荐《机械设计基础—理论、方法与标准(第2版)》的*特色是将《机械设计基础》和《机械设计基础课程设计》两个关系密切的教学内容安排在一本教材之中。经多年教学实践表明,一般的课堂教学和课程设计都是由同一教师,并在同一学期完成的,因此将《机械设计基础》和《机械设计基础课程设计》两本教材合并是可行的,方便教师和学生使用。另外,现在一般图书馆无法提供大量的《机械设计手册》,因此许多学生只能依赖目前《机械设计课程设计》教材中提供的少量数据表格和图线,不仅会导致设计时选择范围大大压缩,学生无法得到较好的训练,甚至有时会选择一些并不适合的数据进行设计,导致设计不合理问题出现。

内容简介
《机械设计基础—理论、方法与标准(第2版)》是根据机械设计基础课程教学基本要求和“高等教育面向21世纪教学内容和课程体系教学改革计划” 文件有关精神,为适应教学改革而编写的。《机械设计基础—理论、方法与标准(第2版)》包含三部分内容,*篇基础理论篇(第1~16章)包括:绪论、平面机构运动简图及机构自由度的计算、平面连杆机构、凸轮机构与其他常用机构、机械调速与平衡、齿轮与蜗杆传动、轮系与传动比、带传动、链传动、螺纹连接与螺旋传动、键连接与销连接及其他常用连接、滑动轴承、滚动轴承、联轴器与离合器、轴、弹簧。各章附有一定数量的思考题和习题。 第二篇设计方法(第17~19章),包括:机械传动装置设计总论、结构设计、课程设计参考图例及设计题目。《机械设计基础—理论、方法与标准(第2版)》还包括了机械设计常用国家标准和设计规范、试题与解答以及常用词汇的中英文对照等13个附录。 《机械设计基础—理论、方法与标准(第2版)》可以作为高等学校近机械类专业机械设计基础与课程设计教材,也可作为有关工程技术人员参考书籍。
目  录
第1篇基础理论篇

第1章绪论

1.1机械的组成

1.2机械零件常用材料及其选用

1.3机械零件的失效形式及设计准则

1.4机械设计的基本要求及程序

1.5机械传动系统的传动方案设计
前  言
教师和学生在多年教学实践过程中,对本书第1版提出了很多修改建议,在此基础上,本版对第1版进行了较大幅度的改版和修订。主要修改的内容如下:
(1) 本版保留了前版的基本构架,将原书的理论、方法与标准三篇中的前两篇保留在纸版图书中,而把原版附录的国家标准列表放入二维码中,从而通过二维码扫描查询,以精简全书的篇幅。
(2) 增加了理论教学部分的全部章节的慕课视频二维码和部分教学内容的动画二维码,以方便学生学习时对所学内容更深入理解和课后复习时参考使用。
(3) 调整了本书的部分章节和内容的顺序,如将原第5章的轮系调整到原第7章齿轮传动与蜗杆传动的后面,以便在讲解完齿轮后,读者具有一定齿轮知识之后再介绍轮系的传动比计算。同时,对相应的必做题的顺序也做了调整。
(4) 实践中,我们感觉到系列类的题目具有较好的连贯性和系统性,因此本版在原来只有一组减速器设计系列题的基础上,增加了一组关于内燃机设计的系列题。其内容包含机构简图绘制、机构运动分析和平面连杆机构设计等内容,这些内容分别安排在第2、3章和第6章中。
(5) 对原版的错误进行较为详细的勘正。

第3章平面连杆机构
连杆机构是各构件之间用低副连接而成的机构,故又称为低副机构。它分为平面连杆机构和空间连杆机构两大类,本章只讨论平面连杆机构,它的应用非常广泛,而且是组成多杆机构的基础。
3.1平面四杆机构的基本形式和特性
MOOC
连杆机构中全部用回转副组成的平面四杆机构称为铰链四杆机构,如图3.1所示。机构的固定件杆AD称为机架; 与机架用回转副相连接的杆AB和杆CD称为连架杆; 不与机架直接连接的杆BC称为连杆。能作整周转动的连架杆称为曲柄,仅能在某一角度摆动的连架杆称为摇杆。对于铰链四杆机构来说,机架和连杆总是存在的,因此可按照连架杆是曲柄还是摇杆,将铰链四杆机构分为三种基本形式: 曲柄摇杆机构、双曲柄机构和双摇杆机构。3.1.1曲柄摇杆机构在铰链四杆机构中,若两个连架杆中一个为曲柄,另一个为摇杆,则此铰链四杆机构称为曲柄摇杆机构。图3.2所示为调整雷达天线俯仰角的曲柄摇杆机构。曲柄1缓慢地匀速转动,通过连杆2使摇杆3在一定的角度范围内摇动,从而调整天线俯仰角的大小。
