Describe

The retractable fixed ball cage type synchronous universal drive shaft coupling is a transmission component that combines innovative design and excellent performance. Its exquisite structure is composed of a star sleeve (inner raceway), a ball shell (outer raceway), a steel ball, a clamp, a dust cover and a cage. On the inner wall of the cylindrical shell and the outside of the star sleeve, the unique cylindrical straight groove design, with the steel balls precisely placed therein, combined with the stable positioning of the steel balls by the cage, and the six well-lubricated transmission steel ball raceways on the inner and outer ball seats, ensure stable and efficient power transmission.

When working, the power starts from the transmission shaft and reaches the output end smoothly through the conduction of the steel balls and the spherical shell. No matter how the angle between the shafts changes under complex working conditions, the coupling can ensure the synchronization of the input shaft and the output shaft speed with its ingenious structure to achieve smooth and accurate power transmission.

In terms of performance, it has all the advantages. High transmission efficiency is its significant highlight. The power loss changes almost linearly in the range of shaft inclination. Under normal working conditions, the transmission efficiency can reach 0.98. With excellent angular compensation capability, the angle between the two shafts can be flexibly changed from 0° to 45°, and it can cope with various installation and operation environments. At the same time, it also has good telescopic performance, which can effectively absorb the vibration and impact during the operation of the equipment and reduce system losses. In addition, the coupling rotation channel is processed with high precision, and each component is a uniform rotating body. After strict dynamic balancing experiments, high dynamic balancing accuracy is guaranteed, and the operation is stable and reliable.

In the automotive field, it is used for front-wheel drive vehicle half-axles and four-wheel drive vehicle drive shafts to ensure smooth power output; in industrial machinery, such as machine tools, heavy machinery, etc., it provides solid support for the stable operation of equipment. With its compact structure, easy installation, good sealing, and long life, the retractable fixed ball cage type synchronous universal drive shaft coupling has become an ideal choice for power transmission in many industries.
