Dec 10, 2018

For many years, there have been frequent purchases of universal joints, which are confused with couplings. What is the difference between a universal joint and a coupling:

The universal joint is a type of coupling for the mechanical transmission member, and it can be said that the universal joint belongs to the coupling.

There are many types of couplings, such as plum coupling, expansion sleeve coupling, elastic coupling, parallel coupling, diaphragm coupling, universal coupling, etc., all of which are couplings, type Different, the selection and use conditions are also different.

Universal joints are also called universal joints, and universal joints are often used in applications where the torque is large and the two shafts are poorly concentric.
