接不同机构中的两根轴(主动轴和从动轴)使之共同旋转以传递扭矩的机械零件。一般动力机大都借助于联轴器与工作机相联接,是机械产品轴系传动最常用的联接部件。万向联轴器用于两轴有较大偏斜角或在工作中有较大角位移的地方,它有多种结构型式,例如:十字轴式、球笼式、球叉式、凸块式、球销式、球铰式、球铰柱塞式、三销式等。其中,十字轴式万向联轴器是应用量较大的万向联轴器。
十字轴式万向联轴器是一类容许两轴间具有较大的角位移的联轴器,适用于有较大角位移的两轴之间的连接,一般两轴的轴间角最大可达
35°~45°,而且在运转过程可以随时改变两轴的轴间角,其最大特点是:具有较大的角向补偿能力,结构紧凑,传动效率高。
但在生产和应用的过程中,十字轴式万向联轴器存在着一系列的的问题,如轴承座螺栓断裂、十字轴断裂等。此次设计的目的是为了对这些问题进行深入的分析,并进行合理的改进,以避免其再次出现。

Abstract
I graduated ponents for the cross shaft universal coupling. Common areas of mechanical ponents used to connect two different agencies in the shaft (driving shaft - 1 -

and driven shaft) to make it to transfer mon rotating mechanical parts. Most of the general power machine with the help of coupling links the machine work; mechanical products monly used drive shaft connection parts. Universal coupling for the two-axis deflection angle or greater have a greater angular displacement of the work place, it has a variety of structural types, such as: cross-axis, ball cage, ball fork, bump-type, -ball type, ball and socket type, plunger type ball joints, three pin type and so on. Among them, the cross-axis is the application of universal coupling
universal coupling a large amount.
Cross-axis is a type of universal coupling between the two axes to allow a larger angular
displacement of the coupling for a larger angular displacement of the connection between the two axes, the general two-axis angle between the axis up to 35 ° ~ 45 °, but also in the running process can be changed at any time between the two axes of the shaft angle, and its most important feature:
a large angle pensate for capacity, compact, high transmission efficiency.
But in the process of production and application, cross shaft universal coupling
