摘   要

曲轴是用来支撑轴承的，固定轴承的外圈，仅仅 让内圈转动，外圈保持不动，始终与传动的方向保持一致（比如电机运转方向），并且保持平衡；,曲轴的概念就是轴承和箱体的集合体,以便于应用,这样的好处是可以有更好的配合,更方便的使用,减少了使用厂家的成本.至于形状,多种多样,通常是一个箱体,轴承可以安装在其中。随着科学技术的不断进步，它在国民经济中占有越来越重要的地位，发展前景十分广阔，尤其是在汽车和电子电器等高速发展的领域。本次课程设计设计的课题就是曲轴的设计，是在学完汽车制造工艺学后进行的一项教学环节；在老师的指导下，要求在设计中能初步学会综合运用以前所学过的全部课程，并且独立完成的一项工程基本训练。

Abstract

The Crankshaft seat is used to support the Crankshaft outer ring, inner ring for fixing the Crankshaft outer ring rotation, let alone, keep still, always keep consistent with the direction of transmission (such as motor rotation direction), and keep the balance; and aggregate concept is Crankshaft and the Crankshaft seat, in order to facilitate the application, so that the benefits of cooperation can be better, more convenient to use, to reduce the use of cost for manufacturers. As for the shape, variety, is usually a box can be installed in the Crankshaft. With the continuous progress of science and technology, it plays a more and more important role in the national economy, the development prospect is very wide, especially in the automotive and electronic appliances such as the rapid development of the field. The course design is the subject of the Crankshaft seat design, is a teaching link in the completion of the manufacturing technology of automobile; under the guidance of the teacher, to a full course of primary learn the integrated use of previously learned in the design, the basic training and independence completion of an engineering.
