摘要
本文主要设计汽车减速器壳体。
汽车主减速器是驱动桥重要的组成部分,它的功用是将万向传动装置传来的发动机转矩传递给驱动车轮,是汽车传动系中减小转速、增大扭矩的重要部件。可以使主减速器前面的传动部件,如变速箱、万向传动装置等传递的扭矩变小,同时也减小了变速箱的尺寸和质量,使得操控灵敏省力。
通过了解减速器壳体的功用,技术特性,结合减速器壳体的制造过程,来确定参数;然后进行设计计算,并结合生产工艺过程,使之结构简单、合理,容易加工,工艺性能好。
该论文研究的是减速器壳体的工艺设计,其中包括零件的分析,零件的工艺规程设计,毛坯尺寸确定及加工余量的确定,加工工时和切削用量的计算等内容。
通过这个毕业设计,熟练运用CAD等软件,同时巩固以往所学的知识(汽车设计、汽车构造、机械设计等)。在设计上具有全面的思路,结合遇到的各种实际问题进行综合考虑,以求达到设计要求,提高自己分析问题与解决问题的能力。

Abstract
In this paper, design a car gearbox shell。
Automotive drive axle final drive is an important part of its function is universal gear came to pass to the drive wheels the engine torque is reduced speed auto transmission lines, increasing the torque of the important parts. Can make the front of the transmission main gear ponents, such as gearboxes, cardan drive torque transfer devices e smaller, but also reduces the transmission size and quality, making the manipulation of sensitive effort.
By understanding the function of the reducer housing, technical features, combined with the reduction gear housing of the manufacturing process, to determine the parameters; then design calculations, combined with the production process, so simple, reasonable, easy to process, process performance.
The thesis is the design process reducer housing, including parts of the analysis, part of the process planning, and allowances to determine the rough size determination, processing time and the calculation of cutting content.
With this graduation, skilled in using CAD and other software, while reinforcing previously learned knowledge (automotive design, automotive construction, mechanical design, etc.). Designed with a full line of thought, combined with a variety of practical problems encountered in the integrated
