摘要
轴承座是用来支撑轴承的，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；轴承座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，尤其是在机械领域。本次毕业设计设计的课题就是轴承座的设计；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。

    Bearing is used to support bearings, bearing outer ring, just let the inner ring rotation, keeping outer ring, always keep up with the direction of transmission (such as motor running direction), and keep balance;And the concept of the bearing is bearing and the housing assembly so that the application of such benefits is can have a better cooperate with the use of more convenient to reduce the cost of using the manufacturer as to shape a variety is usually a bearing box can be installed in it. With the constant progress of science and technology, it occupies more and more important position in national economy, the development prospect is very broad, especially in cars and with rapid development of electronic appliances and other fields. The subject of this course design of design is the design of the bearing, after learning the auto manufacturing technology is a teaching link; Under the guidance of the teacher, the requirement in the design preliminary learn to the integrated use of previously learned all courses, basic training and independently of a project.
