Universal couplings have a variety of structural types, such as: cross shaft type, ball cage type, ball fork type, bump type, ball pin type, ball hinge type, ball hinge plunger type, three pin type, three fork rod type , Three ball pin type, hinge type, etc., the most commonly used is the cross shaft type, followed by the ball cage type. In actual applications, it is divided into heavy, medium, light and small according to the transmitted torque.
The cross-shaft universal coupling is a large-scale universal coupling, and the bearing is a vulnerable part of the cross-shaft universal coupling.Several large cross-shaft universal couplings are mainly different from the changes in the bearing housing and cross fork, and form different structural forms. In order to ensure the synchronization of the main and driven shafts, the double type is adopted in actual applications. The connection method of the joint is nothing more than welding or flange connection by bolts, and there are many forms of changes in the length of the middle.
