建立了十字轴设计计算时的力学模型，并进行了力学分析；

It founds an analysis model and then does the mechanics analysis while doing the design calculation of the cross-axle.

十字轴式万向节

Universal joint cardan universal joint

其主要部件包括十字轴 、 万向节叉以及滚针轴承等.

The main components of a spider cardan joint include the spider , yokes and quill bearings, etc.

最后将该方法用于RCCC空间机构以及进一步用于十字轴方向联轴器中，并取得了较为满意的结果。

At the end of this chapter this method is used in analysing RCCC space mechanism and further more in a cardon joint and the results are satisfactory.
