What Is the Difference Between A Universal Shaft and A Universal Joint?

The universal shaft utilizes the characteristics of its mechanism to achieve continuous rotation of the connected two shafts and reliably transmit torque and motion when the two shafts are not on the same axis and there is an angle between the axes.

The characteristics of a universal joint shaft: its structure has a large angular compensation ability, a compact structure, and high transmission efficiency. Universal couplings with different structural types have different angles, typically between 5 and 45 degrees.

Universal joints refer to the use of spherical and other devices to achieve shaft power output in different directions, and are important components of automobiles.

The structure and function of a universal joint is somewhat similar to the joints of human limbs, which allows the angle between the connectors to change within a certain range.
