| 万向节是实现转轴之间变角度传递动力的部件。 The universal joint is a component which can transfer power from one shaft to another. 如果万向节在扭转方向没有弹性、动力靠零件的铰链式连接传递，是刚性万向节，刚性万向节又分为不等速万向节（如十字轴式万向节）、准等速万向节（如双联式、三销轴式等）和等速万向节（如球叉式、球笼式等）。 If the universal joint has no elasticity in the torsion direction, and the power is transmitted by the hinge connection of the parts, it is a rigid universal joint. The rigid universal joint can be divided into non constant velocity universal joint (such as cross shaft universal joint), quasi constant velocity universal joint (such as double joint, triple pin shaft type, etc.) and constant velocity universal joint (such as ball fork type, ball cage type, etc.). 如果万向节在扭转方向有一定弹性、动力靠弹性零件传递、且有缓冲减振作用，是弹性万向节。 If the universal joint has a certain elasticity in the torsion direction, the power is transmitted by the elastic parts, and the damping effect is buffered, it is an elastic universal joint. 汽车上应用较多的是刚性万向节。 Rigid universal joint is widely used in automobiles. 一、十字轴式刚性万向节 1、 Cross shaft type rigid universal joint 十字轴式刚性万向节结构简单、工作可靠、且允许所连接的两轴之间有较大交角，在汽车上应用最为普遍。 The cross axle type rigid universal joint has the advantages of simple structure, reliable operation and large angle of intersection between the two connected shafts, so it is widely used in automobiles. 1．构造及润滑 1.
