Cross axis universal joint is the most commonly used type of joint, which has the following main characteristics:
Large angle compensation capability: The cross axis universal joint can compensate for large axis angles, allowing two axes that are not on the same axis or have large axis angles to rotate continuously at equal angular velocities and reliably transmit torque and motion.
Compact and reasonable structure: The use of integral fork heads improves the reliability of transportation, while the compact structure is easy to install and maintain.
Large bearing capacity: Compared with other types of couplings with the same rotational diameter, the cross axis universal joint transmits greater torque, making it particularly suitable for mechanical equipment with limited rotational diameter.
High transmission efficiency: Its transmission efficiency reaches 98-99.8%, suitable for high-power transmission, and has a significant energy-saving effect.
Smooth transportation and low noise: The cross axis universal joint provides smooth transportation and low noise, providing a good working environment.
In addition, the calculated torque and allowable speed range of the cross axis universal joint are determined based on the allowable linear velocity of different materials of the universal joint and the difficulty of adjusting the alignment of the two shafts in large machinery and equipment, in order to absorb and reduce the fluctuation of the output torque of the diesel engine, reduce the impact on the gear surface during torque variation, and protect the normal operation of the mechanical equipment. The selection of cross axis universal joint also needs to consider its structural type. According to the magnitude of the transmitted torque, it is divided into heavy, medium, light and small types to meet the needs of different application scenarios
