Constant Velocity Joint (CV Joint) Bearing Cage

Design Principle The annular symmetric structure contains 6-8 ball cavities, and guides the ball rolling trajectory through arc-shaped guide grooves; the multi-directional adaptive geometric design ensures constant velocity transmission at a maximum swing angle of 47°, and integrated machining reduces assembly errors. Performance Characteristics Constant Velocity Transmission: The trajectory optimization design makes the speed fluctuation ≤ 2% and improves the power transmission efficiency by 15%. Multi-directional Adaptation: The maximum swing angle is 47°, meeting the needs of steering and suspension movement. Low Vibration: The symmetric structure combined with vibration-damping materials reduces operating noise by 50% compared with traditional designs. Long Service Life: Precision cavity machining reduces ball wear, with a service life of 150,000 - 300,000 kilometers.

The core structural design of the CV joint bearing cage adopts an annular symmetric structure with 6-8 ball cavities, which are integrally formed through precision injection molding or forging processes. This ensures that the ball spacing error is ≤ 0.02mm, and the fitting degree between the arc-shaped guide grooves and the ball contact surfaces reaches over 95%, which can reduce contact stress. In terms of its lubrication and wear resistance mechanism, it stores lubricating grease through the oil storage structure of the cavity, and the guide grooves guide the lubricating grease to evenly adhere to the surface of the steel balls to reduce rolling wear. At the same time, wear-resistant fibers are added to reinforced nylon, and the surface of bronze parts is plated, which doubles the wear resistance. For stability guarantee, materials such as PEEK used to replace steel can reduce weight by 30% while maintaining structural strength. The symmetric geometric design can balance centrifugal force, ensuring that the radial runout is ≤ 0.04mm at a rotating speed of 3500-5000rpm. The coordination of materials and processes is reflected in that the reinforced nylon injection molding process can form complex cavities to meet vibration reduction requirements; the precision forging of phosphor bronze combined with plating treatment can improve fatigue resistance and corrosion resistance; the combination of PEEK composite materials and guide groove design can achieve self-lubrication and extend the maintenance cycle.
