Details Description

In mechanical transmission, torque is transmitted between the shaft and the shaft. In the master-slave drive, the torque must be transmitted by a coupling or other transmission method, and with the improvement of the degree of mechanical automation and machining accuracy, especially for the use of servo motors, stepper motors, encoders, and other high-precision automation. In the case of precision machinery, the coupling becomes an indispensable coupling. The reason for this is that the coupling has its own unique advantages.

In addition to the most direct transmission of the torque generated by the torque source, the coupling can absorb the radial deviation, the angular deviation, and the composite deviation when the two shafts are connected, effectively ensuring the mechanical Normal operation, thereby extending the life of the machine. At the same time, it can also attenuate the vibration generated by the torque source to ensure smooth transmission of torque.

Characteristics:

The common feature of the universal coupling is that the angular compensation amount is large, and the angles of the two axes of different structural types of the universal coupling are different, generally between ≤5°-45°.
The universal coupling makes use of the characteristics of its mechanism, so that the two shafts are not in the same axis, and can realize the continuous rotation of the connected two shafts when there is an angle between the axes, and reliably transfer the torque and movement.
Cardan shaft has compact structure, large transmission torque, long service life, and long-term use under severe working conditions.

Cardan Shaft Drawing

The universal joint can be widely used to transfer torque in mechanical shafting of metallurgy, lifting, engineering, mining, petroleum, marine, coal, rubber, paper machinery, and other heavy machinery industries. We can supply the customized cardan shaft according to your requested specifications and sizes.

Universal Joint

The universal joint is a joint that connects two levers. The joint consists of a pair of ordinary hinges with a relative orientation of 90°. The lever can be turned in any direction and is still widely used in the transmission of steel rolling mills. The structure and function of the universal joint are somewhat like the joint on the limbs of the human body, which allows the angle between the connected parts to vary within a certain range.
