The universal joint is also the universal joint. I believe that everyone should not be too unfamiliar with it, and there should be some understanding of the corresponding. Then you must have heard of the universal joint cross , which is the cross shaft.

The cross shaft, also known as ten bytes, is the universal joint. It is a part that realizes variable-angle power transmission. It is used to change the position of the transmission axis. It is the "joint" part of the universal transmission of the automobile drive system. The cross-shaft rigid universal joint is a variable speed universal joint widely used in automobiles, and the maximum angle of intersection between two adjacent shafts is allowed to be 15゜～20゜. The cross shaft is one of the key parts of the cross shaft rigid universal joint.

With the development and progress of science and technology, there are more and more types and models of universal joints, but like most parts, most universal joints still need to be repaired and maintained. Of course, with the rapid development of science and technology, there are now maintenance-free bearings on the market, which are convenient for people to use in their daily lives, so it has to be said that technology has given humans great convenience.
