毕业论文传动轴的工艺设计.doc

摘 要

传动轴是组成机器零件的主要零件之，一切做回转运动的传动零件（例如：齿轮，蜗轮等）都必须安装在传动轴上才能进行运动及动力的传动，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，只腀@惺芘ぞ囟怀惺芡渚亍ＳΩ檬勾峋哂凶愎坏母斩群透吡俳缱伲岬纳杓品椒ㄊ且圆牧狭ρ。葜岬那慷燃扑愠醵ㄆ渫饩叮萜渌惺艿脑睾扇范ㄈ却砉ひ眨缓笮：肆俳缱俸团ぷ榷ㄐ浴Ｔ谇慷燃扑阒校捎谒〉陌踩凳洗螅佣怪岬某叽绻螅疚奶致鄣拇峁ひ丈杓品椒ǎ⒏菹中泄娣对鎏砹诵┍砻娲淼姆绞奖热绫砻娣⒗肌Ⅻbr>

ABSTRACT

Shaft is composed of the main parts of the machine parts, all made rotary motion transmission parts (such as: gears, worm, etc.) must be installed on the transmission shaft to carry out the movement and force transmission, drive shaft commonly used in the transmission and drive axle the connection between. This axis generally longer, and high speed, can not bear to withstand torque moment. Should be sufficient to drive shaft stiffness and high critical speed, the drive shaft of the design method is based on mechanics of materials, according to the intensity calculated initially for the shaft diameter, determined according to the load they bear the heat treatment process, and then check the critical speed and torsion stability. In the strength calculation,
Given the large safety factor taken, so that shaft size is too large, the paper discusses the shaft design process, and in accordance with existing norms of surface treatment to add some way of example, the surface of flange.





Keywords：Shaft, parts, stiffness, strength, surface flange
