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。期中φ13孔是将轴承座固定的作用孔。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轴承座的设计，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。 【关键词】轴承座工艺规格设计夹具设计工序工艺性 Abstract is used to support beari
