The universal joint drive shaft is generally composed of a universal joint, a drive shaft, and intermediate support. It is mainly used to transmit torque and rotational motion between two shafts whose relative positions are constantly changing during the working process. However, there are many types of universal joints, roughly divided into three categories, unequal velocity universal joints, quasi-constant velocity universal joints, and constant velocity universal joints. Under these three categories, there are other categories, one of which is the precision universal joint .

The precision universal joint is suitable for transmission occasions with two shafts β≤45º on the same plane of the connection space, and transmits the nominal torque of 11.2-1120N.m. It has the advantage of allowing the angle between the two shafts to be changed within a limited range according to the needs of the work. It is widely used in steel rolling machinery, leveling machinery, roll machinery, printing machinery, packaging machinery, woodworking machinery, automobile industry, automation equipment, and other industries.

The classification of universal joints is far more than that, and the universal joint manufacturer is constantly improving the quality of universal joints.
