所谓十字轴万向节，就是在万向节中间存在一个十字形状的零件，两边的轴叉则都在绕着这个十字旋转。因为它们之间存在相对的运动，所以，十字轴万向节也就实现了万向传动的功能目标。十字轴万向节在机械领域内的用途十分广泛，比如维修工具。
The so-called cross universal joint is that there is a cross shaped part in the middle of the universal joint, and the shaft forks on both sides are rotating around the cross. Because of the relative motion between them, the universal joint of the cross shaft also realizes the function target of the universal drive. The cross universal joint is widely used in the field of machinery, such as maintenance tools.
