毕业设计（论文）-减速器传动轴加工工艺及夹具设计.docVIP

 摘 要 通过在校期间对传动轴的学习和认识对传动轴进行一下系统的分析和设计，支承传动件的零件称为轴。轴类零件毕业设计是机械工程类专业学生完成本专业教学计划的最后一个极为重要的实践性教学环节，是使学生综合运用所学过的基本理论、基本知识与基本技能去解决专业范围内的工程技术问题而进行的一次基本训练。这对学生即将从事的相关技术工作和未来事业的开拓都具有一定意义传动轴常用于变速箱与驱动桥之间的连接。这种轴一般较长，且转速高使传动轴具有足够的刚度和高临界转速，强度计算中，由于所取的安全系数较大，从而使轴的尺寸过大，本文讨论的传动轴设计方法强度 ABSTRACT Through the study of shaft during school and transmission of the system are analyzed and design. Supporting transmission parts called shaft. Axial parts of graduation design is mechanical engineering specialty students complete the teaching plan last a very important practical teaching link is to make the students comprehensive use of basic theory, we learned the basic knowledge and skills to solve major problems within the scope of the engineering technology and a basic training. The student is engaged in technical work related to the development and future career has certain Shaft is composed of the main parts of the machine parts, all of the transmission parts motion (for example: gear, gear, etc.) must be installed in the transmission of power to exercise and shaft transmission, often used in the connection between the transmission and drive. The shaft generally is long, and the high speed, can withstand torque not inherit the moment. Should make the shaft has enough rigidity and high speed, strength calculation, because of the large safety factor, thus make shaft dimension, this paper discusses the transmission technology design methods, and according to the current standard added some way of surface treatment Keywords：Shaft, parts, stiffness, strength, surface flange 目 录 中文摘要 Ⅰ 英文摘要 Ⅱ 1概述 1 1.1 问题的提出及研究意向 1 1.2 本文研究的目的和研究内容 2 2零件的分析 1 2.1生产纲领 2.2零件的作用 2.3零件的工艺分析 2.4零件表面加工方法 3加工方案的选择 3.1方案选择 3.2加工的技术要求 4确定毛坯 4.1传动轴毛坯 4.2传动轴材料 4.3确定锻件加工余量 5工艺规程设计 5.1定位基准的选择 5.2热处理方法 5.3拟定工艺规程 5.4加工顺序安排 5.5制定工艺路线 6夹具的设计 6.1夹具的作用 6.2铣床夹具的设计特点 6.3定位原理的几种情况 6.4 6.5 6心得体会 7致谢 8参考文献   1 概述 1.1
