As a type of coupling, the cross shaft universal shaft uses the characteristics of its mechanism to make the driving shaft and the driven shaft not on the same axis, and realize the continuous rotation of the two connected shafts under the angle of the axis, and can transfer the rotation. Moments and movements.
Compared with ordinary couplings, the important feature of cross shaft universal shaft is that the structure of universal couplings has greater angular compensation capability, compact structure, and good transmission efficiency. Generally, cars will use ball cage universal shaft. For agricultural machinery, industrial machinery and other sports machinery will use cross shaft universal coupling.
The surface of the cross universal coupling should be carburized and quenched or tempered. The hardness of the surface obtained is different depending on the method. Gas carburizing The workpiece is loaded into a closed carburizing furnace, and a high-carbon surface layer is obtained by gas or liquid carburizing agent.
cross shaft universal shaft is a universal component of mechanical foundation, which is suitable for two axes with skewed axis and relative position often changing. The advantage of the cross shaft type universal coupling is that it transmits large torque, has angle compensation capability, and has a compact structure.
