The definition and structure of universal coupling

Publication time: November 2016, 03【L Small

  The universal coupling utilizes the characteristics of its mechanism, so that the two shafts are not on the same axis and can realize the continuous rotation of the connected two shafts under the condition of the axis included angle, and reliably transmit torque and movement.The big feature of universal coupling is: its structure has a large angular compensation ability, compact structure and high transmission efficiency.The angle between the two axes of universal joints of different structures is different, generally between 5°-45°.

  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 commonly used is the cross shaft type, followed by the ball cage type.In practical applications, according to the size of the transmitted torque, it is divided into heavy, medium, light and small.
