Describe

RSK fixed CV Joint (ball cage constant velocity joint) is a high-performance transmission component specially designed to meet the needs of harsh working conditions. Its structural design is precise and mainly consists of a ball cage outer ring, a star-shaped inner ring, a cage and a force-transmitting steel ball. The ball cage outer ring and the star-shaped inner ring are firmly connected to the driving and driven shafts respectively. The centers of the force-transmitting steel balls are located in the plane passing through the center of the coupling and are 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 spherical surfaces coincide with the center of the universal coupling, ensuring the accuracy and stability of the operation.

In terms of working principle, in order to ensure that the centers of all steel balls are always on the bisector of the angle between the two shaft axes, the steel balls are installed in the window of the cage. In this way, when the angle between the driving and driven shafts of the coupling changes, the force transmission point can continue to be on the bisector of the angle, so that the speed between the driving and driven shafts remains synchronized, achieving stable and efficient power transmission.

This product has excellent performance in wear resistance. Key components are made of high-strength wear-resistant steel, and are processed by advanced processes such as precision forging and cold extrusion to ensure the stability of the internal steel structure and greatly improve the wear resistance of the material. At the same time, the surface is specially treated with anti-corrosion to further enhance the product's ability to resist erosion in harsh environments and significantly extend its service life.

It has a wide range of application scenarios, especially in the automotive, metallurgical, light industry, heavy machinery and other industries, where shaft transmission under conditions of large inclination angles and restricted radial dimensions can provide reliable power connection and transmission guarantees for various types of mechanical equipment.
