Introduction of universal coupling
There are many types of universal coupling structure, such as: cross shaft type, ball cage type, ball fork type, bump type, ball pin type, ball hinge type, ball joint plunger type, three pin type, triple rod type, three ball pin type, hinge rod type, etc. The most commonly used type is the cross shaft type, followed by the ball cage type. The common feature of the universal coupling is that the angular compensation is large, and the angle between the two axes of the universal coupling with different structure types is not the same, generally ≤ 5 ° to 45 °. The universal coupling makes use of the characteristics of its mechanism, so that the two shafts are not in the same axis, and there is an angle between the axes, which can realize the continuous rotation of the two connected shafts and reliably transfer the torque and motion. The biggest characteristic of universal coupling is that it has larger angular compensation ability, compact structure and high transmission efficiency. In practical application, the torque can be divided into heavy, medium, light and small.
