The large torque fixed ball cage synchronous constant velocity universal coupling is a precision component that plays a key role in the field of modern industrial transmission. With its excellent performance and reliable quality, it has become an ideal choice for many high-demand application scenarios. ​

The coupling is mainly composed of core components such as the ball cage outer ring, the star-shaped inner ring, the cage and the force transmission steel ball. The ball cage outer ring and the star-shaped inner ring are firmly connected to the master and slave shafts respectively. The center of the force transmission steel ball is located in the plane passing through the center of the coupling and is placed in the raceway composed of the outer spherical grooves of the spherical outer ring and the outer spherical grooves of the star-shaped inner ring. The centers of the two spheres coincide precisely with the center of the universal coupling, and the steel balls are installed in the window of the cage. Such an exquisite structural design ensures that when the angle between the master and slave shafts of the coupling changes, the force transmission point is always on the bisector of the angle, thereby realizing the synchronization of the speed between the master and slave shafts, which is also the fundamental reason why it is called a synchronous constant velocity universal coupling. ​

In terms of performance, this coupling has many highlights. Its synchronization is excellent, which effectively avoids the problem of unstable equipment operation caused by speed difference. It has strong buffering and vibration reduction performance, which can significantly reduce the noise during the transmission process and create a quieter environment for equipment operation. Moreover, under the same rotation diameter and inclination angle, its load-bearing capacity can be increased by 0.5-1 times compared with similar products, which is fully capable of transmitting large torque. In both axial and radial directions, it has a large compensation amount, especially in the axial direction, which can be achieved without external splines, greatly simplifying the overall structure of the equipment. In addition, the coupling also has the advantages of novel structure, light weight, good processability, etc., which is convenient for mass production and helps to reduce costs. At the same time, it is reliable in operation, easy to assemble and disassemble, easy to maintain daily, and has a long service life. Whether it is low-speed heavy load or high-speed transmission conditions, it can easily cope with it. ​

High-torque fixed ball cage type synchronous constant velocity universal coupling is widely used in many industries such as metallurgy, mining, engineering machinery, petrochemicals, etc. In large-scale steel rolling equipment in the metallurgical industry, it can stably transmit large torque to ensure the efficiency and accuracy of the steel rolling process; in the excavation and transportation equipment of mining machinery, it can adapt to complex working conditions to ensure stable and reliable power transmission; in the lifting and excavation operations of engineering machinery, it provides strong support for the strong power output of the equipment; in large-scale mixing and conveying equipment in the petrochemical industry, it plays a vital transmission role.
